CHAPTER I INTRODUCTION

1.1. Background Flood in DKI Jakarta is the result of a natural condition and it is due to human activities as

well. The area of DKI Jakarta is approximately 650 km2 and about 40% of its area is in

lowland, which is below the maximum tidal elevation. The intensity and rainfall in Jakarta is

relatively high, ranging from 2,000 to 4,000 mm/year. The rainfall is streamed from upstream

to downstream/sea through 13 rivers that divides Jakarta, where it has a limited capacity of

stream, therefore when the full sea tide, the flows of river water to the sea is blocked at the

same time.

Several community activities which cause impact are deteriorating the flood problem.

Changes on land-use and open areas into built-up areas are also resulting in the erosion

increment. The eroded materials are carried away into the water channels and rivers,

resulting in shallowing the riverbed, therefore those thirteen rivers experience rapid

degradation. This phenomenon gives a negative impact to the streaming capacity which

flows in gravity. This occurs due to the river tilt is becoming more inclined.

In the event of flood management, the government has built facilities and infrastructure of

flood control which include pump, floodgate, river/channel embankment, sheet pile and the

retention basin. There are many flood control buildings which are constructed with significant

costs but they are in poor condition before they reach their technical life. Their functions are

decreasing and neglected due to lack of operational and maintenance works of the flood

control buildings.

The operational and maintenance works are two different activities, but they are inseparable

since it reciprocally affects one another. The drainage system operation means it utilizes the

drainage infrastructure optimally. Meanwhile, the maintenance activity is an effort to maintain

the drainage infrastructure to be always functioning properly for as long as possible,

throughout the planned term of service.

In the event of flood mitigation at DKI Jakarta Province, which is served as the capital city of

the nation, the Government of Indonesia, in this case is Ministry of Public Works of Republic

of Indonesia and the Provincial Government of DKI Jakarta have taken concrete steps. One

of those steps is to take efforts in flood mitigation by dredging the national drains of Cideng-

Introduction


Thamrin which is a part of activities of Jakarta Emergency Dredging Initiative (JEDI) phase II

that is included in the Jakarta Flood Mitigation Project (Jakarta Urgent Flood Mitigation

Project/JUFMP). The project aims to reduce sediment deposits in floodways due to the

sediment and several others factors have reduced the capacity of flood drainage in

floodways significantly.

The implementing agency for dredging the drainage structure of Cideng-Thamrin drains is

Directorate General of Human Settlements (Cipta Karya) of the Ministry of Public Works.

The EIA implementation of dredging of Cideng-Thamrin is performed simultaneously with the

EIA implementation of other dredging activities in JEDI project phase II. Meanwhile, the EIA

works of JEDI phase I has been completed, therefore the implementation of dredging

activities of JEDI phase I will be served as the analogy for dredging of Cideng-Thamrin

drains (JEDI phase II). This EIA study is performed simultaneously with the activities of

Technical Planning Study of Dredging, therefore between EIA Study and Technical Planning

Study, both can reciprocally give feedback related to these dredging activities.

The dredged materials will be used as reclamation material, in the disposal site location,

which is the eastern side of Ancol Barat. This disposal site location has been completed with

the updating study of EIA Reclamation of Ancol Timur Beach in 2009 and has received the

recommendations from BPLHD DKI Jakarta on March 30th, 2009 No. 02/AMDAL/1.-774.151.

Cideng-Thamrin drains which would be dredged in 2010 is included in the territory of

Kecamatan Tanah Abang (Kelurahan Kebon Kacang, Kelurahan Kebon Melati, Kelurahan

Kampung Bali), Kecamatan Menteng (Kelurahan Kebon Sirih) and Kecamatan Gambir

(Kelurahan Petojo Selatan, Kelurahan Cideng).

In accordance with the Law Number 32/2009 on the Environment Protection and

Management, Government Regulation Number 27/1999 on Environmental Impact

Assessment, Decree of Minister of Environment (MoE) Number 11/2006 on Type of

Businesses or Activities which must be prepared with Environmental Impact Assessment

along with its attachments, and Governor of DKI Jakarta Province Stipulation Number

2863/2001 on Type of Business Plan and/or Activities which must be prepared with

Environmental Impact Assessment at the DKI Jakarta Province, therefore these activities

must be prepared with Document of Environmental Impact Assessment, as the water

dredging with volume of ≥ 50,000 m3 must be prepared with EIA document. In order to meet

that regulation, DG of Human Settlements of Ministry of Public Works will conduct an EIA

study on Dredging of Cideng-Thamrin Drains.

Introduction


The writing of this EIA document refers to the Decree of State Minister of Environment

Number 8/2006 on Guidance on the EIA.

1.2. Purpose and Benefit of the Activity

1.2.1. Purpose of the Activity

The purposes of JEDI phase 2 including the dredging of Cideng-Thamrin drains are:

(i) To alleviate the impacts of annual flood in DKI through the priority of rehabilitation and

dredging of existing floodways, drains and retention basins.

(ii) To provide technical expertise through the on-the-job training to strengthen the

capacity of DKI and Ministry of Public Works (MoPW) to operate and maintain the flood

control system in accordance with international standards.

The dredging activities of JEDI Phase 2 is intended to begin the project implementation, and

enable to test the engineering concept of dredging sediment, transport and disposal, as well

as monitoring and managing possible environmental impacts.

1.2.2. Benefit of the Activity

The main benefit of JEDI Phase 2 dredging activities is to reduce the extent of loss caused

by annual floods in the most highly populated areas in Central Jakarta. Other benefit is the

rehabilitation of overall drainage system function

1.3. Regulations and Legislations

The implementation of EIA Study of Dredging of Cideng-Thamrin Drains by DG of Human

Settlements of Ministry of Public Works of RI is implemented based on legislations which

has been established by the government. Some relevant legislations in the effort to manage

natural resources and environment as the legal basis and reference for the DG of Human

2.2. Description of Business and/or Activities Plan

In order to conduct flood mitigation in Province of DKI Jakarta, the Government of Republic of

Indonesia, in this case is the Ministry of Public Works of Republic of Indonesia and the

Provincial Government of DKI Jakarta had taken concrete steps of flood mitigation. One of the

steps is by dredging the national drains, that is Cideng-Thamrin which is a part of the Jakarta

Emergency Dredging Initiative (JEDI) phase II, included in the Jakarta Flood Mitigation Project

(Jakarta Urgent Flood Mitigation Project/JUFMP). This project aims to reduce the sediment in

floodways. Those deposits and several other factors have reduced the capacity of flood

drainage in floodways significantly.

The implementing agency for the dredging activities of Cideng-Thamrin drains is Directorate

General of Human Settlements, Ministry of Public Works. This EIA study is conducted

simultaneously with the activities of Technical Planning Study of Dredging , therefore between

EIA Study and Technical Planning Study, both can reciprocally give feedback related to these

dredging activities.

The dredged materials will be used as reclamation material, in the disposal site location, which

is the eastern side of Ancol Barat. This disposal site location has been completed with the

updating study of EIA Reclamation of Ancol Timur Beach in 2009 and has received the

recommendations from BPLHD DKI Jakarta on March 30th, 2009 No. 02/AMDAL/1.-774.151.

Cideng-Thamrin drains that will be dredged is administratively located in three kecamatan

(district) and five kelurahan (village). Below are the names of kelurahan that are passed by

Cideng-Thamrin Drains:

their own homes to project location. Meanwhile, to meet the needs of meal and drink,

workers will buy from surrounding merchants. In addition, sanitation facilities will be

provided too by the implementing contractor in the form of portable toilets. Water

needs for dredging workers are:

Domestic : 95 persons* x 50 liter/day = 4,750 liters/day

Cleanliness** : 2,000 liters/day

TOTAL : 6,750 liters = 6.75m3/day

Notes: * Only calculated 95 people, as 3 people, i.e. head of project (1 person) and finance administration (2 persons) are working outside the dredging location (project’s office)

** Data from DED

(2) Implementation

(i) Dredging It is planned that dredging activities of Cideng-Thamrin Drain will dredge

materials approximately 300-500 m3/day, therefore the estimated time required

is approximately 10-12 months. It is planned that dredging activities will be

performed by using floating excavator or land excavator for open drains (Kebon

Kacang Raya Bridge - United Nations Building and BPPT Building – Jl. Siantar)



and by manual or using a water jet for closed drains (UN Building - BPPT

Building).

The dredging implementation procedure by using a floating excavator is as

follows:

a) Installation of signs during implementation;

b) Vehicles and dredging equipments are placed at the end of the road of

dredging location;

c) Dredging excavator and pontoon are lowered into the river by using crane

from the bridge or by using ramp. First, pontoon is lowered into the river,

then once it is stabled, the dredging excavator will follow;

d) Excavator (which is now on top of pontoon) and mud pontoon move

towards the starting dredging point which prioritizes the location where

sediment and waste have been accumulated;

e) Excavator starts to dredge from the starting dredging point to the next point.

The procedure by using a land excavator is as follows:


b) Vehicles and dredging equipments are placed at the end of the road of

dredging location;

c) Service excavator starts to dredge from the starting dredging point (which

prioritizes the location where sediment and waste have been accumulated)

to the next point.

The procedure for manual is as follows:


b) Manual workers start to dredge the bottom of drains under the parking

building.

The procedure for Water Jet is as follows:


b) Setting up equipments: pumps, hoses and water jets;



c) Pumps pull out the water from Cideng-Thamrin drains and discharge it to

the water jet;

d) Workers spray the water from water jet to mud that is located in parking

building so the mud will move to the other side of the parking building.

e) Mud that has moved to the other side will be lifted by excavator to dump

truck.

Following is the map of segments and dredging equipments that will be used:

(ii) Temporary Placement of Dredged material

Dredged material, in the form of mud is placed in Temporary Placement Area of

Mud (TPS Lumpur), which is a container that can drain water out of mud and

dry the mud through evaporation process. Container is placed on the drains so

that it can avoid the environmental pollution on the street or the negative

perception from surrounding community. During rainy day or when it creates

sharp odor, the mud pile in the container will be closed. The temporary mud pile

will not be higher than 2 m and the placement time is only for one day.

(iii) Waste Sorting

Before mud is transported to the disposal site at the eastern side of Ancol Barat,

first of all, huge size waste will be sorted/separated by the local community.

These sorted wastes will be transported by truck (in collaboration with

Sanitation Office of DKI Jakarta in technical matters of transportation or the

appointment of the waste operator) to the landfill. The volume of waste is

estimated to be 20% of the volume of mud dredged, which is 33,600 m3.

(iv) Transportation of Dredged material

Transportation of dredged material will be done by a carrier truck which capacity

is 25 m3 and equipped with seal to prevent scattered mud spills. Moreover, it

also organizes trucks transportation routes that transports dredged material for

32 vehicles/day with their own rotation, where each truck has 3 rotations (the

same route is also used for an empty truck). Each day, truck can transport mud

for 2,400 m3. . Dump truck which contains dredged material will go to disposal

site location starting from 22:00 to 05:00 WIB. The transportation routes of

dredged material are as follow:

Alternative 1: Jl. Cideng Barat/Timur Jl. Balikpapan Jl. Suryapranoto Jl. Ir. H Juanda Jl.

Pos Jl. Dr Soetomo Jl. Gunung Sahari Jl. RE Martadinata.

Alternative 2:

Jl. MH Thamrin Jl. Kebon Sirih Raya Jl. Prapatan Jl. Senen Raya Jl.

Gunung Sahari Jl. RE Martadinata.



Meanwhile, waste transportation will be served by 2 units of truck which capacity is 18

m3 with two rotations per day. Waste will be transported to Bantar Gebang Landfill.

The transportation routes of dredged material are as follows:

(v) Placement of Dredged materials

Placement of dredged materials will be done at the disposal site, which is the

eastern side of Ancol Barat that will be used as reclamation materials. The

disposal site management is a separate management with the dredging

management. The management for disposal site will be performed by PT

Pembangunan Jaya Ancol in accordance with the updating study of EIA of

Eastern side of Ancol Barat, while the dredging management is performed by

JEDI Management which overall includes the dredging location and roads which

are passed by dredged materials truck. In accordance with the updating study of

EIA Reclamation of Ancol Timur Beach in 2009, therefore PT Pembangunan

Jaya Ancol does not receive mud which contains hazardous and poisonous

waste (B3).

To identify whether there is the B3 waste in dredged mud, the Directorate

General of Human Settlements of Ministry of Public Works of RI will monitor the

quality of these sediments prior to dredging. Should there be B3 waste, dredged

material will not be transported to and disposed at Ancol Timur, but instead, it

will be handed over to the third party which has Environmental Ministry (KLH)

license.

2.2.1.3. Post-Operational Stage

Upon the completion of operational stage, series of activities at a post-operational stage will

follow which consists of:

(1) Land Clearing

At post-operational stage, the temporary placement area of mud and location

around drains will be cleaned from the scraps of dredging activities. Public

facilities such as traffic signs, fences, plants and parks will be restore to the

original condition.

(2) Demobilization of Vehicles and Equipments

Demobilization of vehicles and equipments is conducted gradually from the

dredging location to the implementing contractor office.

(3) Demobilization of Manpower

Demobilization of manpower will be done after all workers have performed their

duty and accept their rights. Prior to the termination of employment, the



contractor will provide information about it, so workers can prepare themselves

for termination.

(4) Maintenance

The maintenance activities of drainage is performed to maintain the carrying

capacity of drainage which will be done gradually. The work performed is

regular dredging (maintenance dredging), adding pump and improvement of the

embankment;

1. Sheet piling: 470 m

2. Parapet stone masonry wall: 1,100 m

Figure.3.1. Graph of Average Rainfall 1999-2008

The rainfall situation in DKI Jakarta and surrounding areas in average is 146 mm with

the largest monthly rainfall in January for 390 mm, and the smallest monthly rainfall is

in September with the average of 37 mm. Total annual average rainfall is 1,755 mm.

According to Schmidt and Ferguson, a wet month is a month with average rainfall >

100 mm and dry month is a month with the average monthly rainfall < 60 mm, while

the average monthly rainfall between 60 mm-100 mm is categorized as a humid

month.

The study area of rainfall, based on the above theory includes:

%100xetMonthAverageofW

ryMonthAverageofDQ

= 193.13 / 52.15 = 3.7

Based on Schmidt and Ferguson (1951), the value of 3.7 is included in the climate




type class A (0% - 14.3%), therefore generally, the study area is a very wet area

(tropic).

From the outlook of maximum daily rain at 4 observation stations for 14 years (1994-

2007), rain is generally increasing. From this point, it is understandable that the peak

flood which will caused by rain will also be increasing. Due to the peak flood is

increasing, then there should be anticipation by expanding the drainage capacity and

river capacities.

The following tables and figures are the return period of the maximum daily rain in

several areas in Jakarta in 2, 5, 10, 25, 50, 100 and 200 years, and the observation

results of the maximum daily rainfall and its trends from 4 rain stations in Jakarta, as

the reference for drainage planning of Jakarta and surrounding areas.

b. Air Temperature

The annual average of air temperature according to Halim Perdana Kusumah

Geophysics Station for period 1999 - 2008 Jakarta area is 31.6oC where the highest

monthly average is in September with 32.5oC and the lowest monthly average of air

temperature for 30.1oC is in February. Based on rainfall data and monthly air

temperature, we can determine the local climate type according to Köppen climate

type classification, i.e. classified as climate type A, the type of tropical rain climate. In

detail, the air temperature data from Halim Perdana Kusumah Geophysics Station for

period 1999 - 2008 can be seen in Table. 3.4

d. Wind Direction and Speed

The research of wind speed and direction is intended to identify the dominance

pattern of the wind direction and its speed. It is important as it is related to the impact

towards the spread of gas pollutant and particulates which will be generated by the

dredging of Cideng-Thamrin Drain. The wind condition that was monitored during the

period 1998 - 2007 by Halim Perdana Kusumah Geophysics Station showed that




from December to March, wind tended to be from the west, in April and May, it

tended from the east, while from October to November, the wind blew from the north,

wind speed ranged between 1-4 knots. Wind direction and speed can be seen in

3.1.2. Hydrology

Topography of this area is relatively flat, the area that is traversed according to the

district area is; Kecamatan Tanah Abang: Kebon Kacang, Kebun Melati, Kampung

Bali; Kecamatan Menteng: Kebun Sirih; and Kecamatan Gambir;:Cideng. Cideng-

Thamrin is the downstream of Cideng River, as the original catchment area of Cideng

River and the upstream of Cideng River consists of urban villages; Duren Tiga,

Mampang Prapatan, Pancoran, Kuningan Timur, Menteng Atas, Menteng Dalam,

Karet, Guntur, Setiabudi, Kebun Melati, Kebon Kacang, then goes to Kali Krukut. The

length of Cideng River from upstream to the joining with Kali Krukut is 14.50 km, with

catchment area of Watershed (DAS) I = 17.4 km2 or 1740 ha. Ever since the

existence of West Banjir Canal (WBC), Cideng River is divided into two streams;

upstream of Cideng River (before WBC), length of 10.8 km (CA = 1,200 ha) and

downstream of Cideng River (after WBC), length of 4.5 km (referred to as Cideng-

Thamrin Drain) with CA = 540 ha. Near Wisma Nusantara/Kebon Kacang, Surabaya

River is joining with Cideng River. The length of Surabaya River is approximately 5

km, and the catchment area is approximately 200 ha. Therefore, the catchment area

of Cideng-Thamrin drain = 600 ha. Cideng-Thamrin Drain starts from Jl. Raya Kebun

Kacang up to Balikpapan Bridge. This drain length is 3.825 km with average width

river is 15 m and the average water depth is 1 m. Cideng-Thamrin is a creek that also




serves as a drainage surrounds Jl. Thamrin-Kebun Sirih, then joining with Krukut

River (Cideng is tributaries of Krukut river), flows to the north, and finally joining with

Kali Besar and Ciliwung River, flow to Sunda Kelapa Harbour.

Cideng-Thamrin Drain is planned to serve the surrounding area. The width area of

current drain condition is approximately 15 m. The problem encountered is

shallowing due to sedimentation, therefore in rainy season, those drains are quickly

filled and overflowed. To get through the drainage discharge from Thamrin-Kebun

Sirih, it is required to conduct excavation and dimensional adjustment. The flood

height in Thamrin-Kebun Sirih area is around 50-30 cm, especially in environmental

streets and settlements, the flooded area is approximately 6.50 ha along the drains.

Here are pictures of the resulting flood.

Figure 3.12 2002 Flood at Bundaran HI, Jl. Teluk Betung and Kebun Kacang




Figure 3.13 Flood and Drain Condition at Bundaran HI, Jl. Teluk Betung and Kebun Kacang

For drainage planning, it uses the daily rain intensity for 27.07 mm/hour (the same as

Krukut River design) with a return period of 25 years. The concept of how to

overcome/reduce flood is when rain comes as that planning assumption, all water

can be accommodated in the drains (without creating any flood). Therefore, it

requires the excavation of existing drains and normalizes the dimension as maximum

as possible for the flow needs. The Profile of Cideng - Thamrin Drains before

dredging is as follows:




Figure 3.14 Profile of Cideng- Thamrin Drains

Figure 3.15 Cross Section of Cideng- Thamrin Drain Before Dredging

In the figure 3.15., it is shown that at 2.2 km to 2.7 km (around Jatibaru Bridge), the

channel capacity is lower than the incoming water, so the area is flooded.

Meanwhile, the picture of drains that is included in Cideng -Thamrin Drains are as

follows:

Figure 3.16 Profile of Cideng- Thamrin Drains

Drains that are included in Cideng -Thamrin Drains are drains originating from Jl.

Sunda and Jl. Wahid Hasyim. Problems that occurred in drains from Jl. Sunda and Jl.

Wahid Hasyim are:




1. Lack of drainage capacity from drains that flow into the Cideng-Thamrin

Drains (the amount of sediment);

2. Lack of pump capacity (current pump capacity is 0.2 m³/second);

3. There is a bottle neck at location around Jatibaru Bridge.

a. Volume of runoff water

By calculating coefficient, catchment area, and rain intensity, the discharge of runoff

water is follows:

It is identified:

Ti : 0.08 hour

W : 3,825 meter

V : 1.2 m/second

I : 27.07 mm/ hours

A : 600 Ha

C : 0.9

As = 37.5 meter2

Tt = W/V = 1.56 hours

Tc = Ti + Tt = 1.6 hours

Cs = 2Tc/(2Tc+Tt) = 0.68




Q = 0.00278. Cs.C.I.A = 27.89 m3/

hours

Qs = As x V = 30.2 m3/ hours

Q > Qs = Drain is overflowing

Figure 3.21 Catchment Area of Cideng-Thamrin Drains

Overall, Cideng-Thamrin Drain still can accommodate the incoming water, however

there are several locations which their capacity cannot accommodate runoff water.

With the dredging of drains, there will be changes to the water flow rate which can

result in increasing the water volume that can be accommodated thereby it reduces

the occurrence of the water puddle or local flooding during rainy season.

3.1.3. Air Quality

The dredging activities of Cideng Thamrin Drains are activities which can create the

impact towards the air quality, especially during the sediment/mud drying and

mobilization of sediment transportation. It serves as a benchmark that there has been

degradation of air quality in the activities location, an analysis towards air quality is

conducted and compared with the quality standards to identify the impact. The air

analyzed component is the ambient air around drainage. The tested parameters are

SO2, CO, NO2, Oxidant (O3), Hydrocarbon, PM10, Plumbum, and dust (TSP).

Regarding the air quality condition around activities location, it is identified that the

content of the tested parameters is relatively small and none exceeds the quality




standards of ambient air according to the Stipulation Letter of Governor of DKI

Jakarta No. 551/2001. The air quality condition is shown in detail in Table 3.7.

3.1.5. Odor

The dredging activities of Cideng Thamrin Drain are activities which can create the

impact towards air quality, especially during the sediment/mud drying and

mobilization of sediment transportation. It serves as a benchmark that there has been

increasing odor at the site, an analysis towards odor is conducted and compared with

the quality standards to determine the impact. Regarding the odor condition at the

activities location, it is identified that the content of tested parameters is relatively

small and none exceeds the odor quality standards according to Decree of MoE No.

The result of laboratory analysis towards surface water samples at the measurement

location showed varying results. The high value of BOD and COD in all measurement

locations showed a high domestic waste pollution. This gives the assumption that all

Cideng-Thamrin drains become the landfill of domestic activities such as settlement

and office buildings in surrounding. This assumption is supported by high organic

chemicals which exceed the quality standards in all measurement locations.




To see the similarities between the characteristic of water quality between upstream

and downstream, it can use Canberra Index (Numerical Ecology, Legendre and

Legendre 1981) as follows:

jj

jj

YY

YYS

21

21

Description:

S = Similarity Index

Y1j and Y2 j = number of jth parameter at two different stations

N = number of compared parameters

By using Canberra Similarity Index, there is the similarity percentage of 94%, so it

can be said that the characteristic of upstream and downstream is the same.

3.1.7 Solid Waste

The volume of waste carried by the river stream in DKI Jakarta is quite astonishing.

In the last five years, at least 76.385 m³ of waste transported from the automatic filter

machine in 14 rivers in Jakarta (source: www.kompas.com August 25th, 2009).

Several river flow in Jakarta carry waste in a fantastic volume, among others is

Cideng River for approximately 3,098 m³/ month (source: PT Asiana Technologies

Lestary Dohar).

A data released in http://www.dml.or.id/dml5/content/view/124/2/ indicates that about

40 percent of Jakarta’s population, or four million people, dispose their domestic

waste directly into rivers, which empties into Jakarta Bay. According to Gempur

Adnan, the Deputy Minister of Environment in Environmental Pollution Control, 60-70

percent of the total pollution volume that goes into rivers in Jakarta are caused by

domestic waste, household waste, while the remaining 30 percent is generated by

other sources, especially the industrial sector.

In Jakarta, there are 13 rivers with the total average discharge is 112.7 m³/sec,

stream into Jakarta Bay. The waste volume that goes into river in DKI Jakarta is

mentioned in http://metro.vivanews.com/news/read/7651-

sehari_sampah_setara_192_truk_masuk_sungai, where a day it can reach to 768

m³/day or equivalent to 192 units of Fuso truck. Head of Data Collection and

Processing (Pulhata) of DKI Jakarta Provincial Government, Nurjanah, said that

midden in Jakarta’s rivers are very alarming. Waste is derived from the waste

http://www.dml.or.id/dml5/content/view/124/2/

http://metro.vivanews.com/news/read/7651-sehari_sampah_setara_192_truk_masuk_sungai

http://metro.vivanews.com/news/read/7651-sehari_sampah_setara_192_truk_masuk_sungai




production of DKI Jakarta which in one day, it can reach to 6 thousand tons or 27

thousand cubic meters. In percentage, the waste amount in Jakarta’s rivers is about

2.8 percent of all production waste of Jakarta’s population.

According to the field survey results conducted by the Sea Waste Management and

Jakarta Bay Pilot Project, 2006, the waste density in 11 rivers that were surveyed is

ranging from 0.22 kg/liter to 0.42 kg/liter. From that survey, it also obtained the waste

composition data in estuaries which is dominated by plastic waste with figures

ranging from 50.3% to 66.3%. Another waste composition material is waste

wood/leaves/twigs with percentage from 32.69% to 46.84%.

From the visual observation towards the waste existence in Cideng-Thamrin Drain,

generally, the existence of floating waste is not dominant. The floating waste is still

found in not so many numbers around the floodgate of Kebon Kacang. Meanwhile,

the floating waste appears to be carried by the stream in the drain. The following

table is the result of collecting waste samples from Cideng Thamrin Drain.

3.1.8 Sediment

The 1998 FAO Data indicated that the average concentration of heavy metal (mg/kg)

in the form of mercury (Hg) in sediment at Jakarta Bay is 0.6 while the natural

concentration and maximum quality standards is 0.5. The result of TCLP metal

analysis at Cideng-Thamrin Drains recorded that there were no metal detected

except Cadmium, Copper, Chromium, Nickel, Lead and Zinc with concentrations far

below the TCLP standard which has been stipulated in Government Regulation No.

85/1999. On the Measurement of organic TCLP and inorganic TCLP, there is no

parameter that exceeds the quality standards as well. Meanwhile, from the physical

observations result of sediment at Cideng-Thamrin drains, sand is the dominant

parameter. The following table is the TLCP result and sediment textures which are

comparable to 2008 data;

3.2. Components of Environmental Biology

3.2.1. Terrestrial Biota

From the preliminary results of the survey, it is identified that the existing ecosystem

at the activities location is a built ecosystem. Built ecosystem is an ecosystem that

has been developed by the human. On the surrounding of the activities location,

there is a vegetation cultivation consists of garden plants that are dominated by

ornamental plants, such as flowers. From the preliminary survey results, the types of

animal at the activities location found were in the avis class (sparrow and finch),

mammals (rat, cat and dog) and reptiles (chameleon). Animals living in the location of

activities are relatively small number of type.

3.2.2. Aquatic Biota

Water is the resource for the life of animals, plants and humans. One of the biological

parameters that can be used to identify a characteristic of waters is by analyzing its

aquatic biota such as plankton, benthos and nekton contained in drainage channels.

a. Plankton

Plankton, especially phytoplankton are an important organism in waters, namely as

the main chain in the food chain (primary producer). The existence and abundance of

phytoplankton will determine the existence and abundance of zooplankton which is

the first level of consumer in these waters. As the first level of consumer that

connects producer and higher consumer such as fish, the existence and abundance

of zooplankton will determine fish biomass, especially juvenile fish. Moreover,

according to J.W. Nybakken (1982), plankton also can serve as the environmental

quality indicator, particularly waters quality. The observation result in the laboratory is

as follows:

Source: Consultant Analysis Result, 2010

Based on the above Table 3.19, the diversity index in all locations was low. This

index shows the contaminated water quality. In phytoplankton, Chrysophyceae Class

was more dominant in waters than Cyanophyta Class, this is due to Chrysophyceae

Class can adapt with the waters which is relatively contaminated with organic

substances by fixating the oxygen directly from free air. This activities took place in

the morning and afternoon, which causing the diurnal migration for that class. In

zooplankton, the Protozoa Class (adaptation with cilia), Anthropoid (adaptation with




shell), and Rotarian (adaptation with the "rotary" movement) indicate that these

waters have been contaminated with organic substances.

b. Benthos

Benthos, in this case is macrozoobenthos, an organism that is commonly living in the

bottom of waters as detritus feeders or suspension feeders. The existence of benthos

is strongly influenced by substrate condition and physical-chemical characteristic of

waters. Benthos is often used for assessing the contamination status of waters

because of its sessile characteristic, not difficult in collecting them, and still can be

identified even it has been preserved in a long time (Leppäkoski, 1975). According to

APHA (1992), the response of macrozoobenthos community towards the

environmental changes can affect the quality of water bodies, therefore it can be

used to forecast the effect of various activities, such as industrial, petroleum,

agriculture and other land use.

Only gastropod that is found in the waters due to there is the ecological pressure at

the bottom of waters, therefore only Gastropod class that has shell. Based on the

above Table 3.20, the diversity index in all location was low. This index describes the

contaminated water quality.

c. Nekton

Nekton that is found in waters such as drains that will be the dredging location is

typically the nekton organism that has good resistance to adverse environmental

conditions. Based on direct observation in the field, nekton organisms found on these




drains are such as: Sapu-sapu Fish (Hypostomus Plecoptamus) and Cere-cere Fish

(Aphlocheilusi, sp)

3.3. Component of Social, Economic and Cultural

3.3.1. Administration

DKI Jakarta is a lowland area, and half of its territory is below the sea level. With this

condition, it causes several locations become a flood-prone area. In some cases,

flood in DKI Jakarta is categorized in the hazardous level. Flood that occurred in

2007 and 2008 had caused fatalities and several public service offices were not

functioning for several days.

Since few years ago, the DKI Jakarta Government had built canals, in order to

control floods in DKI Jakarta. One of them is Cideng-Thamrin Drain, which connects

Waduk Melati and several drains with Kali Krukut. This canal traverses several

villages including Kelurahan Kebon Kacang, Kelurahan Kampung Bali and Kelurahan

Kebon Melati in Kecamatan Tanah Abang, Central Jakarta which is dense with

permanent buildings, such as Government Offices, Private Offices, Hotels and

Shopping Complexes and settlements. The affect of the management activities of

Cideng-Thamrin Drain has also reached Kecamatan Menteng in Kelurahan Kebon

Sirih and Kecamatan Gambir in Kelurahan Cideng. Cideng-Thamrin Drain has a very

vital function as it is expected to be able to control flooding in Kebon Sirih, National

Monument and the Presidential Palace Complex area.

2005. Some respondents claimed that the water level at that time reached > 100 cm and only

3.4. Components of Built Environment

3.4.1. Public Health

a. Patterns of disease.

As we all know, the dredging project of Cideng-Thamrin Drain is located at Kelurahan Kebon

Melati, Kebon Kacang, Kebon Sirih, Kampung Bali, Cideng and Petojo Selatan. Those villages

are in the district area of Tanah Abang, Menteng, and Gambir. The overview of public health

rate from the incidence of disease in those districts can be assessed from the data obtained

from the district Puskesmas. When the circumstance is understood correctly, not all sick

people seek for treatment place in Puskesmas. Most people based on their personal

experience and other considerations will use other health care facilities such as doctor,

midwife, polyclinic and other type of service. However, considering the data availability and the

role of Puskesmas as the center for community activities and government in health efforts, the

overview of public health rate with treatment data in Puskesmas is reliable.

. Overview of disease incidents in the Kecamatan Tanah Abang and Gambir (Kecamatan

Menteng is not/less urgent, as it only touches the circle at the intersection of Jl. Kebon Sirih

and Thamrin that is included in the area of Kelurahan Kebon Sirih) can be reflected from the

List of Top 10 Diseases with the highest number of patients.

It appears that disease which is associated with environmental health condition still holds

major position. This indicates that it requires awareness on environmental health condition so

that it will not be worsening in time and after the dredging project activities. Such interests are

not just associated with disease and injury prevention efforts, but also the consideration that

every citizen is entitled to have the environment that ensures the people to have a healthy live

as stipulated in laws and regulations. Meanwhile, from the survey conducted, it shows that the

prominent incidence of diseases is influenza and cough.

b. Environmental Health

b.1. Infrastructure of water supply and sanitation

In general, Kecamatan Tanah Abang and Gambir which are located in current city center are

an established area with relatively complete urban facilities. Kelurahan Kebon Melati, Kebon

Kacang, Kampung Bali and Cideng are settlements that had been organized for a long time,

as they are close to the modern city center which is located near National Monument field.

Most of residents have been supplied by drinking water company (PDAM); PDAM installation

for water purification is located in Pejompongan, the administrative area of Kecamatan Tanah

Abang; but small population, due to certain considerations, they are still using groundwater as

their source for drinking/clean water.




For sanitation infrastructure, usually every residential building already has a toilet and there is

no latrine over the river or water channel. Even at the edge of the drains, it has been installed

embankment from concrete pole so it will be neater and more orderly. Recently, with the

growth of office buildings and international commercial buildings, it causes the administrative

area getting wider. Tanah Abang Market, Grand Indonesia, Thamrin City are all located in

Kelurahan Kebon Melati, Kebon Kacang and Kampung Bali in Kecamatan Tanah Abang.

b.2. Healthy Behavior

At the last few years, a campaign to prevent the occurrence of disease diarrhea by a method

to wash hand with soap is being promoted. This method is reportedly very effective. Together

with the method of defecating in latrines for all members of the community, it will give a

significant impact in the prevention of diarrhea and environmental sanitation. Subsequently,

the waste disposal in relation to not causing a brood for flies that becomes the conductor

microorganisms which cause alimentary tract disease. In a brief statement, it is to maintain

and improve personal and environmental hygiene. Matter that is associated with dredging

activities is when the dredging activities deteriorate the quality of environmental health, and

this should be counter-productive to the mentioned efforts. The potential which is likely to

occur is dredged material spills during transportation process from the dredging location to the

disposal site/landfill at the eastern side of Ancol Barat. Spilled dredged materials can create

dust on a hot day and a slippery road during rainy days. Further cause is the impact on the

incidence of respiratory disease when dust flies, and the traffic accidents when the roads

slippery.

3.3.2. Surrounding Environmental Condition

Activities around Cideng-Thamrin Drain are:

1. Offices; Embassy of Democratic Republic of Timor-Leste (RDTL), Surya

Building, United Nations Building, Jaya Building, Menara Thamrin, BPPT

Building, Ministry of Religious Affairs Building, and Bank Indonesia Complex.

2. Settlement; Settlements of Kelurahan Kebon Kacang, Kebon Kacang Flats, and

Settlements of Kebon Sirih.

3. Shopping Mall; Sogo/ Plaza Indonesia and Thamrin Square;

4. Hotel: Grand Indonesia Hotel and Millennium Hotel;

5. Infrastructure: Jati Baru Bridge, Jl. Fachrudin Bridge, Jl. KH Wachid Hasyim Ashari

Bridge, Kebon Kacang Raya Bridge, and Balikpapan Bridge.




3.4.3. Traffic

Access to main roads around the dredging activities is generally classified as easy in the

daytime. When it is associated to the aspect of land use around the location of activities with

the potential traffic generator, it can be said that activities which have taken place have a

considerable potential for generator, i.e. office complex, settlements, trading and services.

Transportation of dredged material is done by the carrier truck which is equipped with a shield

to prevent spilled mud. The transportation routes of dredged material for each drainages

respectively are as follows:

Jl. MH Thamrin Jl. Kebon Sirih Raya Jl. Prapatan Jl. Senen Raya Street Jl.


Based on the observation data at certain hours i.e.: at night from 22:00-24.00 (according to the

transportation plan of dredged material), then the traffic situation can be seen at the following

table:

Currently, the traffic condition around the project site is classified as congested, as it is

traversed by Trans Jakarta. Based on previous study that has been conducted, it shows that

currently, V/C ratio in the peak hour of morning and afternoon time is between 0.78 to 0.9,

means very congested; moreover, there are many crossing plot around this lane, so it often

causes quite a long queue in each intersection with an average of 25-50 m.

However, based on survey result at night (between 22.00 - 4:00 pm) V/C ratio was only 0.1 -

0.2 and the length of queue (night time) between 10 - 25 m in several major intersections

along the transportation route plan for dredged material, such as: Sarinah intersection,

Harmoni intersection and RE. Martadinata intersection where the average delay for each

intersection is only 45 seconds. The traffic situation at night on roads surround the dredging

location of Cideng-Thamrin Drain and the transportation lane are as follows;

CHAPTER 4 SCOPE OF STUDY

4.1. Researched Important Impact

4.1.1. Scoping Processes

Scoping is the preliminary process to determine the scope of problem and to identify

hypothetical important impact related to the activities plan. Generally, scoping is conducted in

three phases; potential impact identification, potential impact evaluation, and classification and

priority scale of hypothetical important impact, as listed below:

4.1.1.1. Impact Identification

In this phase, scoping aims to identify the entire environmental impacts (primary, secondary,

and so on) which potentially will occur as the result of having business and/or activities plan. In

this phase, it only inventoried possible potential regardless their size or importance. Therefore,

in this phase, there is no effort yet to assess whether potential impacts are important and big.

Potential impact identification is obtained from a series of consultation result and discussion

with initiator, the responsible agencies, the concerned community and also supplied with the

field observation result. Moreover, the potential impact identification is also performed by using

impact identification methods as follows:

• Public Consultation

• Simple interaction matrix;

• Flow Chart

(1) Components of the Researched Activities Plan.

Based on description of activities plan described in sub chapter 2.1, the components of the

researched activities plan are as follows:

4.1.1.2. Potential Impact Evaluation

Scoping at this stage aims to remove/eliminate the potential impacts that is considered

irrelevant or unimportant, thus it will obtain a priority list of important impact that is considered

necessary and relevant to be observed in-depth in EIA study. The list of potential important

impact is prepared based on the consideration of matters that is considered important by the

community around the plan activities, responsible agencies and the study team. At this stage,

the list of generated important impact is not systematically organized.

The method used at this stage is a discussion among experts. The activities of major and

important impact identification is done by the plan activities initiators (along with consultant

team of EIA drafter), by taking into consideration the consultation result and discussions with

Scope of Study


responsible agencies and the concerned community. The criteria used in determining the

potential impact evaluation consists of four questions:

1. Is the burden of certain environmental components already high? This is indicated from secondary data analysis and pre-survey result.

2. Do those environmental components play a role in the everyday life of community (social and economic value) and against other environmental components (ecological values)? This is seen from the pre-survey result.

3. Is there any high public concern regarding the environmental component? This is indicated from the public consultation results.

4. Are there any rules or policies violated by these impacts? This is indicated from the rules that set the environmental quality standards.

Every potential impact is filtered with those four questions, if one of questions is answered with

"yes" or "unknown" then the environmental components are researched in EIA. After having a

discussion among experts, several potential impacts are removed. Here is the potential impact

evaluation that becomes hypothetical important impact.

(1) Pre-Operational Stage

(i) Public Perception

This is the initial reaction from community, after the dissemination of the dredging plan of

Cideng-Thamrin Drains. This reaction can be a positive or negative impact. Therefore, in

Dissemination, it requires an explanation that is clear, transparent and easy to

understand by participants. It is expected that after the dissemination, Head of Urban

Village and Village Council and existing NGO can provide an explanation to residents on

the purpose and objectives of activities. Based on that idea, the team believes that the

public perception around Cideng-Thamrin Drains in Pre-Operational Stage is made as a

hypothetical important impact.

(2) Operational Stage

(i) Ambient Air Dust Quality

In the form of dust parameter, derives from the mobilization of heavy equipments

material, dredging activities, disposal site and transportation activities. This impact

becomes hypothetical important impacts as it can cause public health, comfort

disturbance and will cause negative perception from public (agitation).

Scope of Study


(ii) Odor Level

It derives from mud removal and accumulation of mud from drain to outside of the drain.

This impact becomes a hypothetical important impact as it can cause public health,

comfort disturbance and will cause negative perception from public (agitation).

(iii) Noise Level

Noise derives from the mobilization of heavy equipments-materials, dredging activities,

and transportation activities. This impact becomes a hypothetical important impact as it

can cause public health, comfort disturbance and will cause negative perception from

public (agitation).

(iv) Sediment Quality

The dredging activities of Cideng-Thamrin Drains will generate dredged materials which

mostly in the form of sediment and others are solid waste. During the dredging process,

the process of sediment transfer from the drain to temporary placement area and

transporting vehicle will pollute the air in the form of their odor, disturbs the

environmental aesthetic if there are spills in dredging location and transportation. This

impact becomes hypothetical important impact as it can cause public health disturbance

and will create negative perception from public.

(v) Physical and Chemical Quality of Surface Water

It derives from dredging activities, where the activities intend to facilitate drainage in

drains and sediment transportation from drainage to the dumping site location, so the

dredging activities will reduce the TSS value in water, thus this impact can be made as a


(vi) Solid Waste

Besides generating dredged material, the dredging of Cideng-Thamrin Drain also

produces solid waste. The existence of solid waste at Cideng-Thamrin drain is not in a

large number, however if it is not well-managed after it is taken out from the drains, it will

impact the public health, causing odor and disturb the aesthetic. Therefore, based on

those matters, the existence of solid waste can be made as a hypothetical important

impact.

Scope of Study


(vii) Aquatic Biota

It derives from the dredging, where it facilitates drainage in drains and sediment

transportation from drainage to the dumping site location. The aquatic biota that is found

during the survey is not a rare biota, this impact is not made as a hypothetical important

impact.

(viii) Terrestrial Biota

It derives from mobilization of vehicles and equipments and dredging activities, where

this activities will cause disturbance to the terrestrial biota, both flora and fauna. The

activities from the disposal site also affect the terrestrial biota. Terrestrial biota found

during the survey is not a rare biota; this impact is not made as a hypothetical important

impact.

(ix) Public Perception

It is an accumulation of all important impacts. If the management of all activities at

Operational Stage was not properly managed, it will cause residual effects which will

continues to Post-Operational Stage. If the management of all activities and the impact

were not properly managed, then it turns into public agitation. This public agitation is very

important as the next level can turn into public anger. In certain parts of Cideng-Thamrin

drain, considering the distance between the settlements and the drain is very close, so

the impact of this activities is highly influential in public life, therefore the public

perception in this area is a hypothetical important impact.

(x) Employment Opportunity

In Operational Stage, the arising positive impact is the manpower component. The

impact on this component has a continued impact such as increasing of public income.

Based on pre-survey result, the community expects that this activity can accommodate

the existing manpower. From the observation, dredging activities will use equipments

that require special expertise, which may not be owned by local manpower. The needs

for local manpower only on several type of works. If this impact can be properly

managed, it will give security to the community and the implementing activity. Yet

instead, if it was not properly managed, it will cause public agitation. Based on this

consideration, therefore employment opportunity is classified into a hypothetical

important impact.

Scope of Study


(xi) Business Opportunity

The impact on business opportunity can be the positive impact if community gets the

opportunity to do business, such as providing meal, drink and other necessities for

workers. This impact can also change the public perception to negative if it was not

properly managed. Based on those considerations, this impact can be made as a


(xii) Public Health

Dredging of drains and retention basins will produce sting odor due to the elevated

sediment and it will causes odor to the surrounding community of project activities. This

disturbance can result in the public health and comfort of life for the surrounding

community of affected area. Moreover, in transporting dredged material from dredging

location to the disposal site, other than odor disturbance, it is also due to spills of

dredged material which will make the surrounding environment dirty. The possibility that

can occur from spilled dredged material on the road that is passed through is the

emergence of dust when the road is dry, and slippery road when it is wet (e.g. rainy day).

The excessive dust will affect the incidence of respiratory tract diseases; while the

slippery road can cause traffic accidents that may cause injury and/or death. With such

conditions, the impact on public health is a component that is potentially create impact

which can be considered as a hypothetical important impact.

(xiii) Environment Aesthetic

Dredging and disposal transportation has the potential to create disturbance of

environment aesthetic. The environmental condition, especially aesthetic problem at the

initial stage of activities will decrease, and it will get better when the dredging activities

and disposal transportation is finished. Because it is only temporary and it will get better,

then the component of environment aesthetic is not included as a hypothetical important

impact.

(xiv) Traffic

It derives from the mobilization of heavy equipments-materials, dredging activities,

disposal site and transportation which potentially cause traffic disturbance. Based on

that, this impact can be classified into a hypothetical important impact.

Scope of Study


(xv) Road Condition

By performing transportation of dredged materials, then it is potentially damaging the

road, it becomes a hypothetical important impact, as roads that will be passed through

are the main street.

(3) Post-Operational Stage

(i) Ambient Air Dust Quality

It consists of parameters of CO, temperature, NO2, SO2 and Pb, derived from the

demobilization of heavy equipments, maintenance and vehicles as well as cleaning of

spills from dredging activities. This impact becomes a hypothetical important impact due

to it may result to the public health, comfort of life and it will create a negative perception

from the public (agitation).

(ii) Noise Level

It derives from the demobilization of heavy equipments, maintenance and vehicle. This

impact does not become a hypothetical important impact as it has low impact intensity.

(iii) Solid Waste

It is in the form of solid waste from remains of work. By looking at the analogy with the

dredging that has been done on JEDI Phase 1, the solid waste generated was not too

much, therefore, based on these matters, solid waste cannot be a hypothetical important

impact.

(iv) Terrestrial Biota

It derives from the return of land such as planting plants, where this activity will improve

vegetation, but this impact does not become a hypothetical important impact as it is in

small number.

(v) Public Perception

Management of all activities on Operational and Post-Operational Stage should be

properly managed. The successful impact management on public perception component

will ensure the smoothness of following activities. The management of all activities and

the arising impact that are not properly managed will turn into public agitation. Therefore,

the public perception is included in the hypothetical important impact.

Scope of Study


(vi) Employment Opportunities

In Post-Operational Stage, there was workforce reduction. It is estimated that most

workers will have termination of employment. This will not cause any shock to the

community life which has started to stabilize, as workers are already aware that this job

will be ended. Based on this thought, the impact of employment opportunities is not

included in the hypothetical important impact.

(vii) Environmental Aesthetics

By the completion of dredging activities and disposal transportation, it will create a clean

and good environment. The environmental aesthetic merit depends on the government

and community activities. If the aesthetics condition can be improved and maintained

properly, then it becomes a better environment aesthetics. Due to its temporary and

subjective nature, the environmental aesthetic component is not included as the


(viii) Traffic

It derives from the demobilization of heavy equipments and vehicle. The demobilization

of heavy equipments and vehicle will cause disturbance to the transportation system if it

was not properly managed. Based on this, the impact can be classified as a hypothetical

important impact.

(ix) Road Conditions

With the demobilization of equipments and vehicle, then it is potentially damaging the

roads, this becomes a hypothetical important impact, as those roads that will be passed

through are the main street.

(x) Flood

Flood reduction is the purpose of this dredging activity, therefore this impact is a

Scope of Study


Based on the above explanation, it can be concluded that hypothetical important impacts are: 1. Pre-Operational Stage

1. Public Perception 2. Operational Stage

1. Ambient Air Dust Quality 2. Odor Level 3. Noise Level 4. Sediment Quality 5. Surface Water Quality 6. Solid Waste 7. Employment Opportunity 8. Business Opportunity 9. Public Perception 10. Public Health 11. Traffic 12. Road Condition

3. Post-Operational Stage

1. Ambient Air Dust Quality 2. Public Perception 3. Traffic 4. Road Condition 5. Flood

4.1.1.3. Classification and Priority of Important Impact

Scoping that is performed at this stage aims to classify/organize the important impact that has

been formulated in the previous stage with the intention to get the classification and priority of

a hypothetic important impact that will be reviewed further in EIA document. In conducting

classification and priority, these following matters should be taken into account:

• Policy or regulation that will be the basis for further EIA assessment directive, such as

standard/quality standards, and so on;

• The scientific concept of research that will be conducted

Those hypothetical important impacts are formulated in two phases. First, the entire major and

important impacts are classified into several groups according to their relation to one another.

Second, those important impact groups are then sorted based on their importance. The priority

method of hypothetical important impact is by predicting the probability of impact created and

estimating the scale of consequences that may occur. Then, the probability of incidence will

have a gradation value that represents the gradation of consequences scale, as in below table.

Here is the classification of hypothetical important impact based on potential impact

evaluation.

1. Pre-Operational Stage:

1. Public Perception 2. Operational Stage

1. Ambient Air Dust Quality and Odor Level 2. Noise Level 3. Sediment Quality 4. Quality of Surface Water 5. Solid Waste 6. Employment and Business Opportunity 7. Public Perception 8. Public Health 9. Traffic and Road Damage

3. Post-Operational Stage

1. Ambient Air Dust Quality 2. Public Perception 2. Traffic and Road Condition 3. Flood Reduction

After obtaining several hypothetical important impacts for each activities stage, then those

impacts will be sorted out based on their importance, so it can be seen as follows:

1. Pre-Operational Stage: because there is only one impact, Public Perception, therefore it

is automatically become a hypothetical important impact at this stage.

2. Operational Stage: there are twelve impacts and the determination of priorities is as

follows:

After going through scoping stages by using interactions matrix method and flow chart, the

hypothetical important impacts that arise as the result of activities plan are:

1. Ambient Air Dust Quality and Odor Level; impact on air quality derives from the

mobilization of equipments and vehicle, dredging activities, mud transportation, land

clearing, and demobilization of equipments and vehicle. Therefore, the measured key

parameters are: Dust or according to Decree of Governor No.551/2001 on ambient air

quality standards and Odor parameter (ammonia, methyl mercaptan, hydrogen sulfide,

methyl sulfide and styrene) is in accordance with the Regulation of Ministry of

Environmental No. 50/1996 on Standard Odor Level.

10. Employment and Business Opportunity; comes from the mobilization and

demobilization of manpower. The measured parameters are the number of manpower and

unemployment figures.

4.2. Area of Study and Research Deadline

The definition for study margin of Environmental Impact Study of Dredging of Cideng-Thamrin

Drains emphasizes on the consideration of the affected area by project activities in every stage

of activities. The study margin is a resultant from the project margin, ecology margin, social

margin and administrative margin with due regard to the technical margin that that includes

limitation of resources, time, fund, techniques and research method. The basic for determining

area of study explains in detail as follows:

(1) Project Margin

Project margin includes the entire area designated for dredging the Cideng-Thamrin

Drains and transportation route for material:

Length : 4150 meters

Width : 15 meters

From Jatibaru Bridge – Jl. Balikpapan

(2) Ecology Margin

The ecology margin is the distribution space of impact from left and right side of

Dredging of Cideng-Thamrin Drains and roads that are traversed by trucks carrying the

dredged material within a radius of 100m to eastern part of Ancol Barat. The estimated

impact distribution of an activities plan is based on waste transportation media (water,

air), where the natural process that occurs in that media is predicted to experience

fundamental changes. The prominent built sub-ecosystem surrounds the activities

location is transportation activities, residential area/settlements, office, hotel &

restaurant, public facilities, shopping mall & shopping complex.

(3) Social Margin

Social margin is a space around the activities location that serves as place for several

social interactions which has several established certain norms and values (including

social system and structure), in line with the social dynamics process of a community

group, that is forecasted to experience a fundamental change due to the plan of

Scope of Study


Dredging Activities of Cideng-Thamrin Drains. Considering the environmental impacts

are not evenly distributed, the social margin is set by limiting several RT (average of 200

meters from the drainage to roads that are traversed by truck carrying dredged material

to disposal site). This social margin is determined by considering the community

identification result that reside in project and ecology margin, and community that reside

outside project and ecology margin but is potentially impacted by the fundamental impact

of Dredging Activities of Cideng-Thamrin Drains through manpower absorption,

construction of public facilities and social facilities

(4) Administrative Margin

Administrative margin is intended as a space where people can do their socio-economic

and socio-cultural activities unreservedly in accordance with the applicable laws and

regulations. The referred space margin is the space margin that is bordered with villages

that is passed through the Dredging Activities of Cideng-Thamrin Drain:

Important Impact Prediction

Environmental Impact Assessment (EIA) [V-1] Dredging Activities of River, Reservoir and Lake Phase 2 (JUFMP / JEDI) Segment of Cideng-Thamrin

CHAPTER 5 IMPORTANT IMPACT PREDICTION 5.1. Criteria of Impact Prediction In making prediction for major and important impact, firstly, there should be indicated the

arising hypothetical important impacts, with reference to:

- Scoping of EIA as written in TOR-EIA;

- The arising environmental issues as the research result. Towards the indicated arising hypothetical important impacts above, then by using

various methods of impact prediction, as proposed in TOR-EIA, an important impact

analysis is conducted to know the nature of impact, the size of impact and the importance

level of impact, which subsequently will be used in evaluating the important impact.

The criteria of important impact is defined based on nature of impact, the size of impact

and the importance level of impact as follows:

a. Nature of Impact The nature of impact is classified to positive impact, which is the types of impact that will

give advantages should it be reviewed from the environmental area, and negative impact,

that is the types of impact that will be damaging should it be reviewed from the

environmental area. The examples of negative impact are such as environmental

pollution, environmental damage, or the decreasing of natural resources potential.

b. Size of impact The size of impact can be classified into two categories, big and small size, which its

determination based on the size of the arising environmental quality changes as the result

of dredging plan of Cideng-Thamrin Drains or the size of environmental quality changes

prior and after activities, whether quantitatively or qualitatively. Moreover, the impact

formula that is categorized as big impact is when there is a suitability with one of these

following criteria:

(1) The environmental carrying capacity has been in a critical condition means it cannot

be functioning to support human life and/or other living creatures as expected.

(2) The capacity of water resources, air and land is in the maximum capacity limit to

accept external additional load.



(3) The capacity of social resources is in the capacity limit to accept external additional

load.

For the purpose of quantitative analysis, the administration of a numerical rating scale is

conducted as follows:

(a) The size of impact is categorized as big, if changes in environmental condition that

occur due to activities reach above or equal to 50% of the original environmental

condition.

(b) The size of impact is categorized as small, if changes in environmental condition

that occur due to activities reach less than 50% of the original environmental

condition.

c. Importance Level of Impact

In accordance with Stipulation of Head of Environmental Management Agency No.

56/1994, then the arising impact that can be categorized as important if there is a

suitability with one of following criteria:

1) The number of people affected by important impact in the study area is exceeding the

number of people who take benefit;

2) The distribution and the extents of affected area is perceived regionally or nationally;

3) Intensity and the duration of impact;

4) Threshold of environmental quality standards start to be exceeded ever since the

activities began and it continued until the post-operational stage;

5) There is a synergize between the predicted arising impacts;

6) The arising impact is irreversible, although there has been a mitigation attempts.

In detail, the criteria to determine important impact can be seen in table 5.1

The number of primary environmental component is less than the secondary impact

5. The nature of cumulative impacts Not cumulative, it can be assimilated by the environment

Cumulative and synergistic, cannot be dissimilated by the environment

6. Reversible or irreversible impact

It can be restored by human engineering

Cannot be Restored (irreversible)

Based on TOR-EIA, there are some priorities of hypothetical important impact:

Pre-Operational Stage 1. Public Perception Operational Stage 1. Ambient Air Dust Quality and Odor Level 2. Traffic and Road Condition 3. Noise Level 4. Sediment Quality 5. Solid Waste 6. Quality of Surface Water 7. Employment and Business Opportunity 8. Public Perception 9. Public Health Post-Operational Stage 1. Flood Reduction



2. Traffic and Road Condition 3. Ambient Air Dust Quality 4. Public Perception 5.1.1. Prediction of Importance Level of Impact A. Pre-Operational Stage 1. Public Perception This pre-operational activity is a dissemination of the activities plan that is conducted through

the mass media, public hearings, and interviews are predicted to arise important impacts on

public perceptions at the activities location which if it was not handled properly then it will have

a continued impact to the public agitation. The occurrence of impact whether positive or

negative ones in the community is described as follows:

Dissemination of Planned Activities: The dissemination conducted through mass media on

November 7, 2009 and public hearing on December 8, 2009 had given an impact to the

society, which can lead to a positive or negative impact. In essence, the dissemination process

is an interaction process between initiator with the affected communities due to the dredging of

Cideng-Thamrin Drains. It is possible that in the openness era; public will voice their

aspirations openly and directly. The positive impact will arise when the dissemination process

is performed in the right way, in timely manner and on target. This way, public will fully know

the benefit of dredging plan of Cideng-Thamrin drains for the good life of the surrounding

community, that is to anticipate the occurrence of flooding that is caused by the high sediment

content as the result of spatial misuse. In addition, another benefit is to restore the level of

riverbed to original level.

On the contrary, the negative impact will occur if the initiator attitude in the dissemination

process is a one-way communication, without bothering the community aspiration, especially

when there is no definitive explanation regarding the control of drain banks (although there is

no action whatsoever in controlling flood plains). Therefore, it is feared that it will create public

agitation, especially for those who live at drain banks. Moreover, we cannot ignore the

possibility of parties who are not satisfied with this plan, because a plan is often cannot satisfy

all parties. These dissatisfying parties will provoke the community, which likely result in social

agitation. Therefore, it requires a prudent attitude from the initiator in this dissemination

process. If necessary, the initiator involves parties who have credibility and capability in the

dissemination/interaction process (e.g. NGOs, universities, consultants, traditional leaders or

community leaders, etc.) to manage the dissemination process in such a way, for this process

to run smoothly. Here are the results of the public hearing conducted on November 7, 2009.

1. Rivers after dredging should always be maintained/preserved/under supervision;



2. When will be the exact time of dredging implementation?

3. Based on the previous experience of dredging, it is expected to restore the environmental

condition after dredging to the previous condition;

4. Need to be clearer on dredging techniques;

5. Should consider the placement of dredged material;

6. Prior to the dredging implementation, the contractor must coordinates with community

leaders;

7. Need to have a hotline information at project sites to accommodate inputs/suggestions

from the community;

8. Should involve the community in the project implementation and in general, they are very

supportive with the project plan.

Preliminary survey: involving the public interest and in line with the era of information

transparency, therefore the dredging planning will be the discourse and topic of concern of the

community in the study area. Moreover, the preliminary survey is a physical activity that can be

seen directly by the community. When the public interest is disturbed which can create an

impression that it will cause losses in material/immaterial, then it is the beginning where

community will react negatively.

At the time of dissemination and during the survey was conducted, it has been described that

this activity will be solely to dredging implementation without any public order, but it is possible

that this information will not reach the whole community. This is seen from the survey result

where there were people who still not aware of this activities. Following is the summary of the

interview result conducted towards the community:

Figure 5.4 The Reason Why Respondent Agree

From the above summary, it appears that most people (97%) were not aware of dredging

activities and this becomes the indicator that the information on dredging activities contained in

the dissemination that was held in Jakarta was not known by the public, especially the

community near the drains. Of the total respondents who were aware of this, it indicated that

100% of respondent agreed and the reason is they expect the drains to be clean and there

would be an environmental improvement, that is overcoming the flood. Alongside respondents

who agreed and disagreed, there were 3% respondents who were still hesitant or not aware of

this, which made it as the task of the Directorate General of Human Settlements, Ministry of

Public Works of RI and the implementing contractor to manage this activity, so that all

communities can receive significant benefit. Based on the research result of predicted impact

that has been described previously, the impact on public perception is categorized as a Big

Impact.

Furthermore, to determine the importance level of impact, some considerations are used as

follows:

1. The number of affected people is relatively small compared to the number of people who

take benefit, so the impact is not categorized as an unimportant impact (TP).

2. The total area of impact distribution is wider than the study area, so it is considered as an

important impact (P).

3. The impact occurs during the pre-operational stage, but it can expand to the post-

operational stage, so it is categorized as an important impact (P).

4. The affected environmental component is only the public perception, so it is not

considered an unimportant impact (TP).



5. This public perception can be cumulative with other activities around the activities

location, so it is categorized as an important impact (P).

6. This public perception can be restored immediately by having a management, so it is

categorized as an unimportant impact (TP).

From the above several criteria, it can be concluded that the impact on public perception

caused by preliminary survey activities and dissemination is an important impact. B. Operational Stage 1. Ambient Air Dust Quality and Odor Level Impact on the ambient air quality degradation comes from the transportation of heavy duty

equipments and materials. The parameters of air quality degradation are dust and CO, which

is predicted to occur at mud temporary placement area and roads which are passed through

by the heavy duty and mud transporting vehicle along the drainage that will be dredged, thus it

will affect the dredging worker and surrounding community. Based on environmental baseline

data, those air quality parameters are still below the specified quality standards. In addition to

the above, during the dredging and draining mud, it is predicted to cause odor. Based on the

measurement result, the current odor condition is still below the specified quality standards. By

looking at the pilot project result conducted at Kali Mati in 2008, apparently odor was a

temporary impact as it would disappear with solar heating and organoleptic habit adaptation of

workers and surrounding communities.

Based on the environmental baseline where dust is still below the specified quality standards,

then by using the formula of Gaussian level line source, it can identify dust increase and

distribution as below:

C = ( )

σσπ

C = gas concentration /particulate ambient air (gram/m3) L = length of impact sources (m) Q = Total gas/particulate emerged, (gram/sec) Q = b x BM x ρ x vol. x v

b = Gas concentration/particulate in fuel, (%) ρ = fuel density, kg/Lt vol. = fuel volume used each km (Lt/km) V = car velocity (Km/second)

BM = Molecule Weight of fuel

Based on analogy, we will get: b = 0.035 % ρ = 0.67 Kg/hour vol. = 0.2 liter / Km) V = 40 km/hour

U = wind velocity (m/sec)

zσ = coefficient of vertical dispersion, (m) It calculated from:

fcxdz +=σ

For Atmosphere stability, A, c = 440,8, d = 1,941 , f =9,27 z = Surface land elevation, m



BM = 212

Therefore, Q value = 13 gram/seconds.

By taking into account the laboratory analysis result and the number of vehicles, then the

increasing CO and dust is due to mobilization of heavy equipments and mud as follows:

Figure 5.6 Relation between Dust and Transporting Vehicles Velocity Source Consultant Calculation, 2010

Based on the above tables and graphs, then it can be identified that the slower the vehicle is, it

would produce more flue gas and little dust. Meanwhile, the faster the vehicle is, it would

generate more dust compared to the flue gas that would vaporize rapidly due to wind/ due to

wind/breeze from the vehicle. By comparing it with the preliminary environmental baseline,

there were more than 50% changes. The impact of air quality degradation will result in a

derivative impact in the form of public health disturbance. The increased dust will cause

irritation and asphyxiate, while CO will cause the disorder of decreased ability of hemoglobin in

absorbing oxygen. Based on the potential impact that will be caused outside the project

location (off-site), then the air quality impact is categorized as a big impact.



Moreover, to determine the importance level of impact, some considerations are used as

follows:

1. The number of affected people is relatively small compared to the number of people

who take benefit, so the impact is not categorized as an unimportant impact (TP).

2. The total area of impact distribution is relatively wider than the study area. In addition,

roads around the activities location are passed through vehicles, so it is considered as

an important impact (P).

3. The impact occurs during the operational stage, with period of 24 months, so it is

categorized as an important impact (P).

4. The affected environmental component is more than one component (air quality, public

health, micro climate, comfort and the public perception), so it is considered as an

important impact (TP).

5. This air quality pollution can be cumulative with other activities around the activities

location, so it is categorized as an important impact (P).

6. This public perception can be restored immediately by having rains, so it is categorized

as an unimportant impact (TP).

From several above criteria, it can be concluded that the impact on air quality pollution caused

by heavy equipments mobilization activities and physical dredging is negative and important impact.

2. Traffic and Road Condition Transportation of dredged material (mud and waste from river) is predicted to affect the traffic

smoothness around the location of activities, alongside the transportation route and access

road to the disposal area. The activities of dredged material vehicle will result in the increasing

volume of traffic around the location of activities, alongside the transportation route and access

road to the disposal area.

The activities of transporting dredged material will use public/main street, therefore it will result

in the increasing volumes of traffic, both on the dredging location and on route/corridor that is

passed through. The road to be passed through starts from the dredging location in each

segment (segment 1, 2 and 3) through the planned route/corridor, respectively to the location

of disposal area. In segment 1, the operational location has a big impact towards the traffic

around the dredging location, while in other dredging location is relatively a small impact. It is

predicted that almost in all routes has relatively a small impact except at Jl. RE Martadinata

which is the only direct road to the disposal area (Eastern side of Ancol Barat) as those three



existing routes will converge through that road, in fact the dredging activities in other locations

will also pass through this road. Due to those conditions, therefore the transportation activities

has a big impact on the increasing traffic flow at the route that is passed through the vehicle

that transporting dredged material, although it is performed at night where theoretically, the

V/C ratio is small. Furthermore, as in previous description that dredged materials will use a

dump truck with a total of 15 units (capacity: 25 tons) which will be divided into 3 (three)

dredging location. Apart from the working package of Cideng-Thamrin, it will only uses

relatively a small number of truck, however in anticipation of the possibility of parallel work with

other packages, it is still predicted that it will add the load of traffic flow. The impact that is

likely to happen is not only around the dredging location, alongside the transport route

(especially at Jl. RE Martadinata which is the convergence of roads for all other route

packages), but also at the access road to disposal site, which is only 200 meter away from Jl.

RE Martadinata, which means that if several/all packages (19 packages) start their works

simultaneously, then there will be a potential queuing at that location, which it can overspread

to the arterial road.

Nevertheless, as it can be seen in the preliminary environmental baseline that the existing

traffic condition alongside the transportation route plan (particularly at night) tends to be not

congested. It is in accordance with the survey result on the location where its several

intersections have indicators, both the length of queue and low delay time, which respectively

in average, it is 25 meter with 45 seconds of delay time. However, the potential for queuing

and congestion can occur if several packages/working locations are conducted

simultaneously.

Temporary placement of dredged material on the roadside especially at Jl. Cideng Barat/Timur

will affect to the damage of existing park alongside the riverbanks, as well as the transport of

dredged material from rivers that is predicted to impact on the damage of the roadway around

each activities locations, alongside the transportation route of dredged material and the access

road to disposal area. The activities of these dredged materials transporting vehicles will result

in the increasing traffic volume, which sequentially, it will increase the potential roadway

damage/loss of quality around the activities locations, alongside the transportation route of

dredged material and the access road to the disposal area. For the dredged material, it will use

a dump truck with the maximum capacity of 20 m3 and approximately 34 units of truck (axle

load: 25 tons), which is predicted to add the load of traffic flow around the dredging location,

alongside the transportation route until the access road to the disposal area, which in turn has

the potential for roadway damage/loss of quality.



The arising source of impact from this transportation of dredged material that is predicted to

add the road load that can reduce the quality of roadway and the size of impact can be

predicted with following explanation:

Theoretically, the impact of road damage/loss of quality can be explained as follows:

The pavement calculation generally uses the loading vehicle formula, equivalent of

single axle load called as 18 - Kip ESAL, where this figure is the pavement design on

the traffic load in the planned time interval which contains the number of vehicles:

vehicle/day/pcu/day/hour, for each vehicle type (from light to weight, including truck),

damage factor (df) that is a factor which affect the quality of roadway, where dump

truck is categorized as the vehicle that has a high df (1.5 x public/private vehicle). In a

condition where the ESAL road of a lane/section is bigger than the number of design

plan, then that lane will lose its quality of roadway, as well as has a direct impact to the

road life itself.

The picture of size of impact can be calculated with below formula:

( )Pat/PaoLo Lt =

Where: Lt, Lo = The pavement age during and before the mobilization of heavy-duty equipments

especially when dump truck takes place. Pat, Pao = Pavement during and before the mobilization of heavy equipments especially when

dump truck takes place. .

Pa = f (w.n) Where: w = Weight of vehicles that passes through the road (in ton) n = number of vehicle that passes through the road (vehicle/ day).

Based on the activities plan, it will use approximately 34 dump trucks/day or maximum 10

pcu/hour with the following approach: The vehicle lane for this transportation in a condition

prior to the mobilization of heavy-duty equipments especially when dump truck takes place is

w = 25 tons and n = 34 vehicles/day or 5 vehicles/hour. That pavement can last for 5 years (60

months) without any maintenance. During the mobilization of heavy equipments especially

when dump truck takes place is predicted:

w = 25 tons

n = 34vehicles/day or 5 vehicles/hour (5 vehicles @ 8 trips/day)

Lt = 60 months = 4.2months 1,000 t.k/70 t.k



From that calculation result, when heavy equipments especially five dump trucks are operated

with 8 trips/day pass through the planned transportation route of dredged material, then it is

predicted that it will cause damage to the passing roadway for 4.2 months. However, the

damage/loss of quality impact on the roadway in this project, particularly will most likely to

occur at Jl. RE Martadinata, as it is the convergence of roads for all other project plan/route

packages. Both Jedi phase 1 and 2 went to the disposal area (Ancol Timur) when several/all

packages start to be conducted simultaneously, thus the frequency and load of vehicle will

occur continuously/repetition throughout the project.

From the field observation, it is identified that Jl. RE Martadinata has a rigid pavement and one

of the cause of roadway damage/loss of quality, especially on the rigid pavement is the

“fatigue” symptom which is caused by several factors, among others are load repetition.

Based on the above description, the effect will be experienced on the access roads to the

disposal site, such as Jl. Kebon Kacang and Jl. RE Martadinata. Therefore, the arising impact

can be categorized as a Big impact. For that reason, it is better that the initiator conducted the

transportation activities at night so it will not have the potential to increase the traffic

congestion.

By considering the determinant factor of important impact, then:

1. The number of affected people is relatively bigger compared to the number of people

who take benefit, so the impact is categorized as an important impact (P).

2. The total area of impact distribution is relatively wider than the study area, so it is

considered as an important impact (P).

3. The impact occurs during the operational stage (24 months), so it is categorized as an


4. The affected environmental component is more than one component (perception, traffic

congestion, air quality, noise and roadway damage), so it is considered as an important

impact (TP).

5. This increasing traffic is cumulative with surrounding activities, so it is categorized as

an important impact (P).

6. This increasing traffic is reversible, so it is categorized as an unimportant impact (TP).

From several above criteria, it can be concluded that it is negative and important impact.

3. Noise Level



Noise is the unwanted sound. The source of noise impact is the increased transportation due

to the mobilization of heavy equipments, dredging, mud transportation and waste separation.

The noise impact due to increased transportation is experienced by residents who reside

alongside the road that is passed through the heavy duty and mud transporting vehicle. The

increasing noise intensity is due to movement of several moving parts of a vehicle such as

axles, wheels and so forth, therefore the size of increasing noise intensity will highly depend

on the type of vehicle, vehicle velocity, weight of vehicle, and the environmental condition

along the road that is passed through the vehicle. Meanwhile, the noise from immobile source

such as heavy equipments, which is caused by the performance of actuating machine. Based

on the desktop study of Dwi P. Sasongko (Environmental Noise, 2000), then the noise level

caused by the machine are:

Table 5.4 Noise Level of Dredging Equipments (distance is 50 feet)

No Name of Equipments Noise Level (dB(A) 1 Dump Truck 88 2 Service Crane 85 3 Excavator 70 4 Tower Crane 112

Source: Dwi P Sasongko (Kebisingan Lingkungan, 2000) Based on the environmental baseline, the noise level in settlements around the dredging

location exceeds the quality standards. By having a mobilization of equipments and mud, it will

add the number of vehicles that pass through the road, which therefore, it is predicted that it

will increase the noise level at settlements along that road. Based on the literature (Rau &

Wooten, Environmental Impact Analysis Handbook, 1980), the impact of these factors to the

noise intensity can be formulated with the following equation:

By assuming that the number of vehicle to transport dredged materials is 34 units/day and if the vehicle moves with its route with the speed of 35 km/h, then the noise created by each individual trip is as follows:

Figure 5.7 Comparison of Noise and Distance



Based on the calculation result, accordingly, by considering the distance between the closest settlement to the noise source (+ 10 meters), then it is estimated that it will have noise impact for 94.14 dBA (increased by more than 30-80% of the initial noise). When it is compared with Decree of Governor of Jakarta No. 551/1995, the noise level exceeds the quality standards for settlement.

The heavy equipments used can be seen in Chapter II. By using the formula of noise point

sources, then:

Lp = Lw-20Log r -11

Where:

Lp = Noise level in distance (r) from noise source (dBA)

Lw = Noise level in noise source (dBA).

r = Distance between noise source and reviewed location (m).

If it is identified that the noise from excavator is 70 dBA, then the safe distance so this noise will not disturb the community are:

55 = 70 -20 Log r-11 Log r = (70 -55 -11)/20 Log r = 0.2 r = 3 meters

At 3 meters, the noise from excavator will not affect residents, because the closest distance between Cideng-Thamrin Drains is 10 meters.

Therefore, the activity that will create noise impact is the transportation of dredged material. The noise impact can cause physical or psychological disorder, where physical disorders are hearing loss, conversion disorder, as well as sleep disorder, while the psychological disorders are such as annoyance, anxiety, and fear. Based on those reasons, then it is identified that the size of impact can be categorized as a small impact.

Furthermore, to determine the importance level of impact, some considerations are used as follows:


who take benefit, so the impact is categorized as an unimportant impact (TP).

2. The total area of impact distribution is relatively wide compared to the study area. In

addition, roads around the activities location is also the access roads, so it is






4. The affected environmental component is more than one component (noise, comfort

and public perception), so it is considered as an important impact (TP).

5. This increasing noise can be cumulative with other activities at the location activities, so

it is categorized as an important impact (P).

6. This increasing traffic can be restored immediately, proportional with the further noise

source and exposure time, so it is categorized as an unimportant impact (TP).

From several above criteria, it can be concluded that the increasing noise, although it is a

small size, but it is generated when most people are taking their rest (at night time) and there

is no other sources that cause noise, so it is a negative and important impact. 4. Sediment Quality The sediment quality during operational stage will affect to several activities:

a. river dredging

b. waste separation from dredged materials

c. draining of dredged materials

d. transporting dredged materials/sediment to Ancol

River dredging

Dredging of Cideng-Thamrin Drains is predicted to be impacted by the sediment quality and

quantity. The volume of dredged material from Cideng-Thamrin Drain is estimated to produce

dredged material for ± 168,000 m3. Approximately, 98% of that dredging volume (+ 151,200

m3) is in the form of sediment and the rest is solid waste. The sediment quality is potentially

contains heavy metals and hazardous substances that accumulates at the bottom of Cideng-

Thamrin Drains.

Sediment that was just removed from the water will relatively septic because of the

decomposition process. If sediment was not properly managed, it will cause an environmental

contamination, create the smell, and relatively large pile of mass volume which is also

unsightly. The sediment quality is also impacted by the acceptance when it is disposed at the

sediment landfill site -Ancol.

Separation of Dredged Material The sediment separation from dredged material of Cideng-Thamrin drain is expected to affect

the sediment. This activity will produce sediment from dredged material separation. If it was

not properly managed, sediment will cause an environmental contamination and undergoes

the decay process which will create odors. The location of sediments separation from dredged

materials needs to have special attention so that it can accommodate the needs for land to



transfer sediment from dredged material to the draining of sediment location. From a 3,865-

meter length river, it is predicted that it will produce sediment approximately + 168,000m3

during the dredging activities. Based on the preliminary environmental baseline data, it is

identified that the sediment quality is still below the specified TCLP quality standards.

Considering that the activities around the activities location is relatively dense (settlements,

commercial services, etc.) and requires convenience and high privacy, then this needs to be

focused on.

Sediment Draining Mud draining/drying from dredged material of Cideng-Thamrin Drains is expected to be

affected by water quality contained in dredged sediment. If it was not properly managed, the

water contained in the sediment or mud (leachate) will spill to the surrounding environment.

Transporting sediment to sediment landfill (Ancol) The drained sediment will be disposed to a landfill (Ancol). It is estimated that the sediment

volume that must be disposed to Ancol from the dredging of Cideng-Thamrin Drains is +

168,000 m3 during the operational stage. In the implementation of the transporting sediment to

the Eastern side of Ancol Barat, it is necessary to conduct a clear coordination and

cooperation between the implementing party of dredging, draining and transporting. Based on

the above reasons, the impact can be categorized as a Big Impact.


follows:



2. The total area of impact distribution is relatively narrow compared to the study area, so

it is considered as an important impact (P).

3. The impact occurs up to the post-operational stage, so it is categorized as an important

impact (P).

4. The affected environmental component is more than one component (public health,

comfort and public perception), so it is considered as an important impact (TP).

5. This impact is cumulative with other dredging of drains/retention basin, so it is


6. This impact cannot be restored immediately, so it is categorized as an important impact

(P).



From several above criteria, it can be concluded that sediment quality impact is a positive and

important impact.

5. Solid Waste

The existence of solid waste on operational stage appeared in several activities:

a. recruitment/mobilization of manpower

b. river dredging

c. waste separation from dredged material

d. utilization of sorted waste

e. waste transportation to landfill

Recruitment/ Labor Mobilization

The activities of operational worker of dredging of Cideng-Thamrin Drain are predicted to affect

the waste. The worker activities will create domestic waste such as food and beverages

leftover along with its food and drink containers. If it was not properly managed, the waste will

cause an environmental contamination, odor, a gathering place for mosquitoes, flies, mice and

cockroaches that will lead to pest problem. If domestic waste from dredging workers was not

properly managed, then there is a possibility to throw it improperly and go back to the river.

The arising impact will have low intensity, its distribution is limited at each activities location but

it is cumulative with other surrounding activities, and it occurs during the operational stage of

Cideng-Thamrin drains. From the above condition, it is predicted that the important impacts is

negative.

River Dredging

Dredging of Cideng-Thamrin is predicted to have impact on solid waste. The dredging volume

of Cideng-Thamring drains is estimated for ± 168,000 m3. It is predicted that approximately 2%

of that dredging volume (+ 33,600 m3) is in the form of waste, both organic and inorganic

waste. If it is not properly managed, this waste will cause an environmental contamination,

odor, gathering place for mosquitoes, flies, mice and cockroaches, which will lead to pest

problem. The organic waste from the river also produces leachate that can pollute water

bodies/rivers.

Separation of Dredged Material

The waste separation of Cideng-Thamrin’s dredged material is predicted to affect the waste.

This activity will produce waste from dredged material separation. If it was not properly



managed, this waste will cause an environmental contamination and undergoes a decay

process that will create odor.

The location of waste separation from dredged material requires attention so it can

accommodate the needs for land to transport the waste from dredged material to waste

transportation (garbage truck). From a 3,865-meter length river, it is estimated that the waste

produced will be + 33,600 m3 during the dredging process. Based on preliminary

environmental baseline data, it is identified that the composition of 33,600 m3 waste is 87%

inorganic waste and 13% organic waste.

Considering the activities at the surrounding activities location is relatively dense (settlement,

commercial services, etc.) and it requires convenience and high privacy, then this needs to be

focused on.

Utilization of Separated/Sorted Waste

After waste separation from dredged material that was conducted together with the

community, then there is the possibility that the community utilizes the sorted waste for its

economic value. Waste utilization is commonly intended for inorganic waste as it can be

directly sold to the garbage/used goods collector. The utilization of sorted waste needs to have

the attention as it is likely that waste which does not have its economic value will be neglected.

Solid Waste Transportation to Landfill (TPA)

Waste that has been separated from dredged materials will be disposed to landfill (TPA). It is

estimated that waste volume which should be disposed to landfill from dredging of Cideng-

Thamrin drain is + 33,600 m3 during the dredging activities. It is estimated that the number of

garbage truck required to transport waste from the river to landfill is one truck with two trips per

day. During the process of waste transportation, there will be a waste transferring process

from the separation location to the garbage trucks (loading) and the transferring process from

garbage truck to landfill (unloading). During the implementation of the waste transportation to

landfill, it should conduct a clear coordination and cooperation between the implementing party

of dredging with the responsible agency related to waste transportation and disposal at landfill.

If the produced waste was not properly managed, it will impact the health disorder, both on

worker and community. From those impacts, it can be categorized as a big Impact.

By considering the determinant factors of important impact, therefore:

1. The number of affected people is relatively smaller compared to the number of people





it is considered as an unimportant impact (TP).



4. The affected environmental component is more than one component (perception,

environmental aesthetics and public health), so it is considered as an important impact

(P).

5. The degradation on environmental sanitation, cumulative with surrounding activities, so

it is categorized as an important impact (P).

6. The degradation on environmental sanitation, irreversible, so it is categorized as an

unimportant impact (TP).

From several above criteria, it can be concluded that sediment quality impact is a positive and

important impact. 6. Surface Water Quality The source of impact on loss of quality is the dredging activities and placement of dredged

materials, especially in the eastern side of Ancol Barat which will be used as a reclamation

material. Based on the water quality measurement result in Chapter III, generally, the water

quality in Cideng-Thamrin Drains has been contaminated by organic materials. The impact of

water quality changes is the increasing turbidity, due to mud removal by an excavator. This

impact only lasts temporarily, which is when the particles that caused turbidity go down to the

bottom waters due to gravity. By considering gravity, discharge, and water velocity, then it is

predicted that dredging will not result in the increasing turbidity. The impact distribution of the

increased turbidity due to solid lifting of Total Suspended Solid (TSS) with average radius is 1-

2 meters and recovery time is 5-10 minutes. Considering there is a slow water velocity, it will

not push solids particle to downstream, there is no one who uses water at Cideng-Thamrin

drains for their necessities of life, there is no endemic and economically valuable aquatic biota,

it is concluded that the arising impact is categorized as a small impact.




2. The total area of impact distribution is relatively narrower compared to the study area,

so it is considered as an unimportant impact (TP).





4. The affected environmental component is only at the drain, so it is considered as an


5. The water quality can be not cumulative with surrounding activities at the activities

location, so it is categorized as an unimportant impact (TP).

6. The water quality can be restored immediately, so it is categorized as an important

impact (P).

From several above criteria, it can be concluded that water quality impact is a negative and

unimportant. 7. Employment and Business Opportunity The number of dredging worker who involved in this project is 98 people. Based on 2008 BPS

data, the population of Kelurahan Kebon Melati, Kebon Kacang, Kampung Bali, Kebon Sirih,

Cideng, and Petojo Selatan Village that has the potential to work in dredging of Cideng-

Thamrin drains is 1,500 people. With that number, the potential for the local manpower to work

at this project is 6.5% for approximately 24 months. This opportunity is considered as low due

to analogically, contractors bring their own workers. The community involvement as a dredging

worker is based on the needs that are correlated with skills, expertise, and community

education level. The income of local workers during operational stage is following the

minimum wage for DKI Jakarta, that is the daily wage for a non-skilled worker is Rp.36,000-

Rp.60,000 or Rp.850,000-Rp.1,500,000, while for skilled worker, the range of monthly income

is Rp.2,500,000-Rp.5,000,000.

Beside the positive impact, manpower activities also has negative impact in the form of social

jealousy, if in the recruitment process, it is less involving the surrounding community as per

qualification and if this problem was not examined properly, then it will impact the security and

public order issues. Sectors that support the employment needs are those that create business

opportunity such as food stalls, accommodation rental place, transportation service for workers

that can be fulfilled by surrounding community, so it will increase household income for local

residents. Manpower who work at the physical implementation of dredging for 24 months and

spread throughout Cideng-Thamrin Drains is predicted that they are less encouraging the

growth and the increasing number of food and drinks merchants at the surrounding activities

location, because the number of workers are small. Therefore, the arising impact is a positive

impact with relatively small intensity.






2. The total area of impact distribution is relatively wide compared to the study area, so it

is considered as an important impact (P).



4. The affected environmental component is more than one component (perception,

increase per capita and local economy), so it is considered as an important impact (P).

5. Employment and business opportunity is cumulative with surrounding activities, so it is


6. Employment and business opportunity is reversible, so it is categorized as an


From several above criteria, it can be concluded that this impact is positive and important. 8. Public Perception Impact on public perception can be positive and negative. The positive public perception

comes from public’s great expectation on being able to take advantage of the created

employment and business opportunities. That is beside the expectation from surrounding

community on creating a clean environment and flood management.

While negative public perception comes from mobilization of heavy equipments and materials

that pass through a settlement area and dredging activities. The mobilization of equipments

and mud transportation will create a negative impact in the form of loss of air quality

(particularly dust), traffic disturbance, and increased spills. This is shown at the interview

results with respondents. Those public opinions are based on the result of impact prediction on

increased level of dust, traffic and potential spills for more than 50%. Based on the above

description, the impact on public perception, both positive and negative is relatively a big

impact.


follows:

1. The number of affected people is equal to the number of people in the study area, so

the impact is categorized as an unimportant impact (TP).

2. The total area of impact distribution is equal to the study area, so it is considered as an


3. The impact occurs during the operational stage and can continue to the post-

operational stage, so it is categorized as an important impact (P).



4. The affected environmental components are public agitation, convenience and public

order, so it is considered as an important impact (P).

5. This impact is cumulative up to post-operational stage, so it is categorized as an


6. This public perception can be reversed immediately to public agitation, if the public

response and expectation is not regarded, so it is categorized as an important impact

(P).

From several above criteria, it can be concluded that public perception impact which is caused

by dredging activities is an important impact. 9. Public Health Dredging of drains that cause impacts such as loss of air quality, increased noise, loss of water

quality, increased runoff water that will create flood and transportation disturbance as well as

degradation in environmental sanitation will have a continuous impact to the public health of

surrounding community. The source of public health disorder is the air quality condition where

its loss is affected by many factors such as pollution from vehicle exhaust that experiences

congestion, clean water consumption, waste, and puddle. From that source, we can obtain the

relation with health risks before human contact, then it synergize and become a cumulative

impact. These impacts will be exposed directly or through a media or vector. The impact

exposure is affected by people's behavior that is related to sanitation and environmental

health. The community in upstream and around Cideng-Thamrin Drains mostly throw waste to

the provided place, such as trash can, then transported the waste to temporary placement

area (TPS) then disposed them to landfill. In the context of of household wastewater, the

community disposed them to the existing drainage, whereas for feces disposal, the community

has used individual family latrine in the form of a septic tank.

For health facilities and infrastructure, local community has used health facilities such as

Posyandu, Puskesmas, doctor’s office and pharmacy if they are sick. If health facilities in

urban village office seem not sufficient, they refer themselves to the district up to nearest

hospital. In the service for mother and child, based on surveillance report of Health Sub-

Division of Central Jakarta, the community has used the service of midwife, both village and

private midwife.

As per description of the previous prediction of important impact, where at operational stage,

the air quality will reduce for more than 50%, as well as with noise (night transportation) which

increased for 10-30%, so it will cause health disorders such as respiratory infection (ISPA) and

impair quality of life.



With the dredging that alter natural landscapes, it will cut off the ecosystem food chain, so

there will not by any flood used as the spawning grounds for mosquito especially dengue fever

(DBD). Based on above descriptions, it can be concluded that the impact of dredging towards

public health is relatively a small impact, as it is a derivative impact from others, such as air

quality, water quality, noise, and many more.

By considering the determinant factor of important impact, then :

1. The number of affected people is equal to the number of people in the study area, so

the impact is categorized as an unimportant impact (TP).

2. The total area of impact distribution is relatively the same as the study area, so it is

considered as an unimportant impact (TP).

3. The impact occurs during the operational stage, so it is categorized as an unimportant

impact (P).

4. The affected environmental component is derivative component from all impacts, so it

is considered as an important impact (P).

5. The source of public health impact is not only from dredging, but also from surrounding

activities, so it is categorized as an unimportant impact (TP).

6. This public health impact is reversible, so it is categorized as an unimportant impact

(TP).

From several above criteria, it can be concluded that it will be a negative impact if mud was not

properly managed and it can be a positive impact upon the completion of dredging, while

according to its nature, it is categorized as an unimportant impact. C. Post-Operational Stage 1. Flood Reduction From the environmental baseline data, it is identified that rainwater runoff (Q) that goes into

Cideng-Thamrin Drains is 27.89 m3/hr. Meanwhile, the capacity of Cideng-Thamrin Drains (Qs)

before dredging was 30.02 m3/hr, therefore Q < Qs (difference of 2 m3/hr). Overall, Cideng-

Thamrin Drains still can accommodate the incoming water, but there are several flooded

locations:

1. Jalan Thamrin, but this is not due to lack of capacity of Cideng-Thamrin Drains in that

segment, but rather it lacks of drainage capacity from drains that flows to Cideng-

Thamrin drains, mainly from the Jl. Sunda and Jl. KH Wahid Hasyim as there are many

sediments. In addition, other cause is the lack of pump capacity (current pump capacity

is 0.2 m3)

2. There is a bottle neck at location around Jatibaru Bridge



The average depth of Cideng-Thamrin drain is ranging from 0.3 m to 1.5 meters. Therefore,

dredging was done with the design of an average depth of 1.5 meters to 3 meters. The

following is the channel cross-section before and after dredging.

(compared with initial capacity before dredging is 30.02 m3/seconds).

If it is compared with the preliminary environmental baseline, this dredging activity can reduce

the potential flood for > 50%, so the impact is categorized as big.

By considering elements from seven determinant factors of important impact, then:

1. The number of people who will take benefits is more than the number of affected

people, so the impact is categorized as an important (P).

2. The total area of impact distribution is relatively wide and experience basic changes, so

it is considered as an important impact (P).

3. The impact occurs can be continued to post-operational stage (24 months), so it is


4. The affected environmental component is more than one component (public

perception, congestion, economy, and many more), so it is considered as an important

impact (P).

5. The impact is cumulative and synergize with the surrounding existing activities, so it will

be difficult for the environment to dissimilate it, so it is categorized as an important

impact (P).

6. The impact towards runoff water is reversible on the dry season, it is categorized as an


From several above criteria, the runoff water reduction impact is included in the category of

positive and important impact. 2. Traffic and Road Damages The demobilization of post-operational equipments of Cideng-Thamrin drains with 5 heavy-

duty vehicles (weight +/- 25 Tons) which took place for 2-5 days was predicted for not having

any impact on traffic around the activities location, especially that activities was conducted at

night, thus it was not potentially cause any damages to roadway alongside the demobilization

route. Based on the above description, the size of traffic impact and road damage is small.

By considering the determinant factors of important impact, then:

1. The number of affected people is relatively smaller compared to the number of people



it is considered as an unimportant impact (TP).

3. The impact occurs during the post-operational stage and only for 1-2 days, so it is




4. The affected environmental component is traffic during the transportation of heavy

equipments, so it is considered as an unimportant impact (TP).

5. The increased traffic is not cumulative with surrounding activities, so it is categorized as

an unimportant impact (TP).

6. This increased traffic is reversible, so it is categorized as an unimportant impact (TP).

From several above criteria, it can be concluded that it is a negative and unimportant impact. 3. Ambient Dust Air Quality The increasing of air quality pollutants comes from demobilization of equipments. Based on

the preliminary environmental baseline where dust is still below the specified quality standards.

By using the formula of Gaussian level line source, it can identify that the increased and

distribution of dust by calculation the laboratory analysis result and number of vehicle, we will

get an increase of CO and dust due to mobilization of equipments and mud as follows:

When compared with the preliminary environmental baseline, then there are changes of less

than 30% and exposure time is only 1-2 days, therefore the impact on air quality is small.


follows:



2. The total area of impact distribution is the same as the study area. In addition to

activities location, there are roads which vehicle passed them through, so it is

considered as an unimportant impact (TP).

3. The impact occurs during the post-operational stage and only for 1-2 days, so it is




4. The affected environmental component is air quality, so it is considered as an


5. This air quality pollution does not only come from demobilization, but also from

surrounding activities, so it is categorized as an unimportant impact (TP).

6. This air quality pollution can be restored immediately with rain, so it is categorized as

an unimportant impact (TP).

From several above criteria, it can be concluded that the air quality pollution due to

demobilization of heavy equipments is considered as a negative and unimportant impact.

4. Public Perception The impact on public perception can be negative or positive. The community positive

perception comes from land clearing so it would be better around the drains. Meanwhile, the

negative public perception comes from the demobilization of manpower, which although it has

been predicted that the number of worker is relatively small. Based on the above description,

the impact on public perception, both positive and negative, is relatively small. Moreover, to

determine the importance level of impact, some considerations are used as follows:

1. The number of affected people is relatively small compared to the number of existing

people in the study area, so the impact is categorized as an unimportant impact (TP).

2. The total area of impact distribution is relatively small compared to the study area, so it

is considered as an unimportant impact (TP).

3. The impact occurs during the post-operational stage, so it is categorized as an


4. The affected environmental component is the positive public perception, so it is


5. The impact is not cumulative, so it is categorized as an unimportant impact (TP).

6. The positive public perception can turn to a negative impact, especially if community

responses and expectation are not regarded, so it is categorized as an important

impact (P).

From several above criteria, it can be concluded that the arising public perception impact due

to post-operational is considered as an important impact. Prediction on important impact of dredging of Cideng-Thamrin Drains is summarized at the

5.2. Researched Alternatives in EIA Some alternatives which can be developed according to the dredging plan of Cideng-Thamrin:

• Alternative on Dredging Method

The selection method is based on the location condition of Cideng-Thamrin Drain and its

environment. The alternative on dredging method is a floating dredging (excavator) or land

based excavator for open drainage and manual or water jet for a closed drainage (under the

parking area of Jaya Building to Ministry of Religious Affairs Building).

Based on location condition, then: 1. Segment of Kebon Kacang Bridge - Jaya Building

- Floating Excavator: It can be used, but there is a barrier in the form of a bridge

that is an access to Plaza Indonesia, water and gas pipe. By coordinating with

the surrounding activities management, it is expected that this can be resolved. - Land Based Excavator: It can be used, but with this current condition,

riverbanks and roads are used by surrounding community for their business,

that is a motorcycle parking and food stalls. These activities run from morning

(07.00) until evening (22.00). If this location is used, it is feared that it will lead

to negative impact in the form of public agitation. In addition, there is a land

owned by PT Asia Troika +/- 10 hectares, adjacent to the drain, so it requires a

coordination. 2. Segment of Jaya Building - Ministry of Religious Affairs

- Manual: It can be used, but it is feared that it will create HSE, due to lack of

oxygen under the parking lot of those buildings. Besides, there are dangerous

animals such as snake or centipedes, which potentially can disturb the

smoothness of work and safety of worker. From the implementation side, this

method takes longer than using equipments such as water jet.

- Water Jet: It can be used, but it requires larger electrical energy. This can be

solved by a mobile generator, but its placement would cause congestion and

noise.

3. Segment of Ministry of Religious Affairs - Jatibaru - Balikpapan

- Floating Excavator: It can be used, but there is a barrier in the form of bridge,

water and gas pipe, so it needs to remove the floating excavator. By

coordinating with the surrounding activities management, it is expected that this

can be resolved.



- Land Based Excavator: It can be used, but several locations at the riverbanks

and roads are used by the surrounding community and there is a park managed

by Landscaping Services Office of DKI Jakarta with width of +/- 2 meters, it is

feared that it will cause disturbance in accessibility, congestion and negative

impact on society.

4. Segment of Balikpapan - Siantar Pump

- Floating Excavator: It can be used, but there are barriers in the form of bridge,

water and gas pipes, so it needs to remove the floating excavator. . By having a

coordination with the surrounding activities management, it is expected that this

can be resolved. - Land Based Excavator: It can be used, but several locations at the riverbanks

and roads are used by the surrounding community, it is feared that it would

cause a negative impact on society.

• Alternative on Transportation of Dredged Materials

This selection method is based on the road conditions on location and traffic of

transportation of dredged materials from Cideng-Thamrin Drain to Disposal Site at Ancol

Timur. These are the transportation route alternatives:

Alternative 1: Jalan Cideng Barat/Timur Jalan Balikpapan Jalan Suryapranoto Jalan Ir H Juanda

Jalan Pos Jalan Dr Soetomo Jalan Gunung Sahari Jalan RE Martadinata.

Alternative 2: Jalan MH Thamrin Jalan Kebon Sirih Raya Jalan Prapatan Jalan Senen Raya

Jalan Gunung Sahari Jalan RE Martadinata.

Looking at the traffic condition at night and the road condition, it is suggested to use

Alternative 1.

Important Impact Evaluation

Environmental Impact Assessment (EIA) [VI-1] Dredging Activities of River, Reservoir and Lake Dredging Activities Stage 2 (JUFMP / JEDI) Segment of Cideng-Thamrin

CHAPTER 6 IMPORTANT IMPACT EVALUATION

6.1. Research on Important Impact Study of environmental impact is described holistically and causatively on the environmental components of physical-chemical, socio-cultural, public health, and traffic which is predicted to cause fundamental changes because of the dredging of Cideng-Thamrin Drains. The environmental components which will be affected by important impacts (both positive and negative) are researched as an integral and interrelated part or influence each other, forming a system of impact, so it will identify the important impacts that must be managed. Based on Chapter V, then the important impacts are: Pre-Operational Stage 1. Public Perception Operational Stage

1. Ambient Air Dust Quality and Odor Level 2. Traffic and Road Condition 3. Noise Level 4. Sediment Quality 5. Solid Waste 6. Employment and Business Opportunity 7. Public Perception

Post-Operational Stage 1. Flood Reduction 2. Public Perception In evaluating the arising big and important impacts due to the dredging of Cideng-Thamrin Drains, a holistic research has been conducted by using a modified Leopold Matrix (Lohani Than) method. For a holistic research, a research on the arising impacts according to its stages of activities was conducted. 6.1.1. Pre-Operational Stage At pre-operational stage, the predicted arising important impact is the public perception towards the dredging plan of Cideng-Thamrin Drains, both negative and positive perception from the surrounding community. a. Negative Perception is due to concerns that dredging of these drains will lead to water spills from the dredged drains, traffic congestion, and disturbance of parking business at Jl. Kebon Kacang. b. Positive perception is in the form of positive expectation from the community who resides around the location, it should be maintained and developed. This is required so these activities will not be disturbed and run smoothly. Therefore, the community expectation on clean drains and an environmental improvement should be considered and anticipated.



6.1.2. Operational Stage The arising big and important impacts during the operational stage are: a. Ambient Air Dust Quality and Odor Level By operating heavy equipments and operational vehicles, they will create important impact towards air quality around drains, particularly dust that needs to be concerned about, as the activities location is in the area of business activities, offices, and dense settlements. This impact would further disturb the comfort of people who reside near the drains, it can even lead to negative perception from the community. Moreover, the appearance of odor during the operational work is feared by the surrounding people, but based on the analogy with similar dredging, odor will only be generated when mud is accumulated at the temporary placement area of mud, thus this impact should be managed. b. Traffic and Road Damage It comes from the mobility of vehicles that transports mud to disposal site, which is required for the dredging implementation, and is predicted to take place continuously. However, the peak activities will last for ± 24 months, that is during dredging which requires mud removal to disposal site in a large volume and in a short time. From the aspect of traffic congestion on route from Cideng-Thamrin Drains to the eastern side of Ancol Barat, it will not create any congestion problems. However, at temporary placement area of mud, it will create traffic congestion due to mud loading from TPS to a truck. At the entrance road to the eastern side of Ancol Barat, there will be more congestion because there will be a queue of vehicles that transports mud, which is not only from Cideng-Thamrin Drains, but also from other dredging of drains and retention basins in the dredging package of JEDI 2. This traffic impact will potentially affect the road damage which will result in a continuous impact, considering roads around Cideng-Thamrin Drains is the main road of the capital city of Jakarta. c. Noise Level By operating the heavy equipments and operational vehicles, they will create important impact towards noise around the drains, which requires special attention because the activities location is in the area of business activities, offices and relatively dense settlements. The increased noise, despite having a small size of impact, yet it averagely occurred at the time when people are resting (at night) and there is no other sources that produce noise. This impact would further disturb the comfort of people who reside near the drains, it can even lead to negative perception from the community. d. Sediment Quality The dredging activity that affects the sediment quality is the physical dredging activities with the volume of 168,000 m3. This activity is potentially produced heavy metal/hazardous and poisonous (B3) which contained and accumulated in the sediment of dredged material. If the heavy metal/B3 contained in these sediments were not properly handled and managed, it could contaminate the soil and ground water, which eventually will affect the health and the perception of surrounding community. Based on TCLP test result, all parameters indicated a much lower value than what have been defined by PPRI No. 18/1999 which indicated that sediments come from dredged material of Cideng-Thamrin Drains can be accepted as a reclamation material at the eastern side of Ancol Barat. e. Solid Waste



The occurrence of scattered waste will pollute the environment around the loading area and alongside the traversed roads, thus the environment aesthetic on-site activities and along the road will be degraded, which eventually, it will lead to a negative perception from the community who resides around the traversed road and that road users. f. Employment and Business Opportunity The dredging implementation which is predicted to run for 24 months and absorbed dredging workers is an important positive impact which needs to be further developed, especially during the manpower selection process that prioritizes the local manpower. If this was not performed, it will create a derivative impact in the form of creating a negative perception from the community (social envy) around the activities location. In addition, by having the dredging activities, by itself it will create a derivative impact in the form of new livelihoods for surrounding community who is indirectly involved with dredging activities, as well as adding the number of residents who work in the informal sector around the activities location. g. Public Perception This comes from the mobilization of heavy equipments and materials which will pass through a road in settlements and the dredging activities itself. This mobilization of equipments and mud will create a negative impact in the form of decreased air quality (particularly dust), traffic disturbance, and increased spills. 6.1.3. Post-Operational Stage At this post-operational stage of Cideng-Thamrin Drains, there will be an impact on flood reduction and public perception. a. Flood Reduction Based on the prediction result, it indicates that prior to dredging of Cideng-Thamrin drains, in general, it still can accommodate runoff water from surrounding catchment area. However, there are several locations which are still flooded due to lacking of capacity of connection drainage and pump capacity, and a bottleneck. With the dredging of drains, the potential for flood or overflow of drains will disappear. b. Public Perception The impact on the public perception is negative and positive. The positive public perception comes from the land clearing so it would be a better land near drains. While the negative public perception comes from the demobilization of manpower, which although it is estimated that the number of worker is relatively small. Based on the above description, the impact on public perception, both positive and negative, is relatively a small impact. The detailed important impact evaluation of Cideng-Thamrin drains in the operational stage with a modified Leopold matrix can be seen in Table 6.1.

Flood Reduction 6. Noise Level 7. Employment and Business Opportunity 8. Sediment Quality 6.2. Selecting the Best Alternative The best alternative that can be selected in relation to the dredging plan of Cideng-Thamrin drains: • Alternative on Dredging Methods 1. Segment of Kebon Kacang Bridge - Jaya Building

- Floating Excavator: It can be used, but there is a barrier in the form of a bridge that is an access to Plaza Indonesia, water and gas pipe. By coordinating with the surrounding activities management, it is expected that this can be resolved.

2. Segment of Jaya Building - Ministry of Religious Affairs

- Water Jet: It can be used, but it requires larger electrical energy. This can be solved by a mobile generator, but its placement would cause congestion and noise.

3. Segment of Ministry of Religious Affairs – Jatibaru - Balikpapan

- Land Based Excavator: It can be used, but several locations at the riverbanks and roads are used by the surrounding community and there is a park managed by Landscaping Services Office of DKI Jakarta with width of +/- 2 meters, it is feared that it will cause disturbance in accessibility, congestion and negative impact on society.

4. Segment of Balikpapan – Siantar Pump



- Floating Excavator: It can be used, but there are barriers in the form of bridge, water and gas pipes, so it needs to remove the floating excavator. By coordinating with the surrounding activities management, it is expected that this can be resolved.

• Alternative of Materials dredging Transportation Based on Chapter V, the selected transport route was:

Jalan MH Thamrin Jalan Kebon Sirih Raya Jalan Prapatan Jalan Senen Raya Jalan Gunung Sahari Jalan RE Martadinata.

. 6.3. Review as the Basis for Management 6.3.1. Pre-Operational Stage a. Public Perception At this pre-operational stage, the expected arising important impacts are the public perception towards activities plan, either negative or positive perception from the surrounding community. The negative perception comes from the dredging activities and transportation of mud, which is feared that it will affect to the increased noise, and reduced traffic. Considering the surrounding area is dense settlements, then this effect becomes significant, especially in settlements. Meanwhile, the positive perception that is in the form of a positive expectation from the community who resides around the activities location must be maintained and developed. This is required so this activity will not be disturbed and run smoothly. Therefore, the community expectation on having employment and business opportunities can be utilized as much as possible by the surrounding community, and other positive expectations that need to be considered and anticipated. Characteristic of the impact will be a positive or negative important impact and it will continue as long as the activities plan occurs up to the operations stage. The affected community group will cover the community from surrounding village area or wider than the area of action plans. The environmental management that has been conducted is by providing opportunities to the affected people so they will be able to express their opinions and aspirations through the village officers. Directive of environmental management plan is to socialize/disseminate detail activities that are conducted in a transparent manner by involving local community leaders, such as clerics, Village Council, and so forth. In addition, it also provided information through the notice board media along Cideng-Thamrin drains. To accommodate more people's aspirations, the initiator must provide a hotline service and integrated information facility about dredging of Cideng-Thamrin Drains in the form of a web site. Directive of environmental monitoring plan is to analyze information from the community through the hot line service and web site, observation, and interview with purposive random method with the surrounding community.

6.3.2. Operational Stage



a. Ambient Air Dust Quality and Odor By operating heavy equipments and operational vehicles, they will create important impact towards air quality around drains, which needs to be concerned about, as the activities location is in the area of business activities, offices, and dense settlements. This impact would further disturb the comfort of people who reside near the drains, it can even lead to negative perception from the community. With this cumulative impact, it will continuously create disturbance/disorder on public health and the comfort of surrounding community, so it requires a mechanism to reduce the impact on the source. The increased air pollutants at drains environment during operational stage is predicted to occur because of mud mobilization, operational of heavy equipments, and dredging activities. This impact will be cumulative and the affected community groups are the community around drains (larger than the project area): Directives of environmental management plan that will be performed to countermeasure the pollution of air quality are:

• Transporting vehicles must pass the emission test; • Mud dredging can only be done during daytime; • Location of mud draining and waste separation is located in an area further from

settlements and other community activities; • Mud is drained to dry; • Close the top with a tarp to avoid the spread of odor and dust; • Setting the mud pile; • Installation of barrier; • Installation of sign/mark of the location of mud draining and waste separation; • Transportation by special water proof dump truck; • Waste from separation results is transported to landfill; • Scheduling the transport time; • Temporary stop the dredging activities during prayer times; • Provide a sediment trap at CDF location of Ancol; • Provide a janitor at the dredging location; • Required all dredging workers to use PPE; • Provide water tank car that moves behind the convoy of a mud transportation

vehicles; • Temporarily stop the dredging, if there is strong wind (> 5 knots).

Directive of environmental monitoring is to collect sampling every 3 months during dredging of Cideng-Thamrin drains according to the Decree of Governor No. 551/2001 on ambient air quality standards. Meanwhile, the odor is based on quality standards of Decree of Environmental Ministry No. 50/1996 regarding odor quality standards. b. Traffic and Road Damage Placement of material and dredging equipments (heavy equipments) and a temporary location for dredged material (mud and waste) are not performed at the location of city infrastructure; coordination with relevant agencies that is related to urban infrastructure during dredging activities take place, especially with the Transportation Office of Central Jakarta at the dredging location in Jl. Kebon Kacang. This is because the road is relatively narrow and there are many of community activities around the site from morning until night. Often, there are cars parking, kiosks and street vendors around that location which could disturb the traffic smoothness.



Activities at the operational stage of the river dredging that have important impact toward traffic is the transportation of dredged material. It starts from the dredging location, especially at the location of Segment 1 (Jl. Kebon Kacang); material transportation route, especially Jl. RE.Martadinata; and the access road to the disposal area including the temporary placement area for dredged materials (mud and waste), especially at Jl. Cideng Barat/Timur. Those activities affected the increasing volume of vehicles traffic around the activities locations, along the transportation route and the access road to the disposal area which potentially causing a queue of vehicles on the access road to the disposal area and creeping up to Jl. RE Martadinata. Placement of vehicles and dredging equipments (heavy equipments) and other temporary placement for dredged material (mud and waste) are not performed at the location of city infrastructure, as well as the transportation route through the road which is in accordance with their capacity and road classification based on load and capacity of dredged material vehicles. In addition, there should be a coordination with relevant agencies that are related to urban infrastructure and facilities before and during dredging activities, especially, the coordination should be done with Landscaping Services Office at Jl. Cideng Barat/Timur and Public Work Offices for the road class. An activities at the operational stage of river dredging that has important impact for road damage is the transportation of dredged material (mud), especially in the route through Jl. RE Martadinata to the disposal area, where several/all packages/projects of Jedi Phase 1 and 2a operate simultaneously and the whole routes lead to the disposal site using this road. Those activities will result in the increasing load of vehicles traffic around the transportation route that passes through Jl. RE Martadinata to the disposal site. Due to continuous vehicles activities, it eventually can cause road damage/decrease in road quality. Road damage/decrease in road quality due to damage to the roadway around the activities location, along transportation route (especially Jl. RE Martadinata) and the access road to disposal area eventually will further affect the negative perception from community and disturbance in public security and order. The increasing volume of traffic around the activities location, along the transportation route which causes queue, especially at the access road to disposal area, will eventually have a further impact to the loss of air quality, increased noise, the negative perception from community and disturbance in public security and order. These impacts will be cumulative and the affected community groups are the people around drains (larger than the project area). Directives of environmental management that will be done to countermeasure the traffic disturbance and road damage are:

• Installing traffic signs and working signs for dredging project; • Transport of equipments and dredged material (mud and waste) are not

conducted on rush hour in the morning, afternoon and evening, which is between 22:00 to 5:00 WIB;

• Have a traffic control officer at the dredging location, transportation route and the access road to disposal area;



• Provide a water-tank car that operates throughout the transportation process of dredged material or provide a janitor who worked together with local community to monitor and clean up waste and mud spills on the road around the activities location, along the route and the access road to disposal area;

• All trucks that transport dredged materials must be equipped with the tarp/plastic seal or similar to it, so that the dredged material will not be scattered in the street because of leaking, etc., which that will result in slippery road and eventually can disturb the traffic;

• Coordination with Transportation Office of Central Jakarta (especially in Kebon Kacang)

• Restriction on the truckloads of dredged material that should not exceed the load capacity and load of road that will be passed through along the transportation route of Cideng-Thamrin.

• The route that will be traversed by dredging materials must be adjusted to the existing road classification so it will not cause any road damages due to overloading. For the location of Cideng-Thamrin, the truck capacity and maximum load is 20 m3;

• Contractors are required to provide deposit for road maintenance/improvement to Local Government of North and Central Jakarta in complying with the provision of respective local government. For example, as what has been released by the local government of North Jakarta, the Decree of Mayor No. 13/2000 on the establishment of control team of granting dispensation on the use of heavy duty vehicles/ground transportation in North Jakarta;

• Coordination with Landscaping Services Office of Central Jakarta, especially at Jl. Cideng Barat/Timur;

• Coordination with Public Work Office of Central Jakarta (to determine the route based on suitable road classification).

Meanwhile, Directives of environmental monitoring are: • Measurement and direct observation will be more focused on traffic data in the form of

vehicles queuing, including delay that is a part of the travel time constraints which potentially occurs, either on the existing intersection along the traversed route (signaled or not, road-rail crossing) , the queue at the dredging/loading the dredged material location and the disposal area;

• Monitor the roadway condition that is traversed by the vehicles that transports mud; • Frequency of traffic condition monitoring is conducted once a week during the

dredging takes place at Jl. MH Thamrin Jl. Kebon Sirih Raya Street Jl. Prapatan Jl. Senen Raya Jl. Gunung Sahari Jl. RE Martadinata.

c. Noise By operating heavy equipments for dredging and mud mobilization to disposal site, it will produce important impact towards noise at the surrounding activities, which needs to be concerned about, because the location is in the area of business activities, offices and dense settlements, which currently are in a relatively good condition. This impact will further disturb the comfort of residents who live around the activities location, even lead to the negative perception from the community. With this cumulative impact, it would continuously disturb both health and the comfort of road users as well as surrounding resident, so it required a mechanism to reduce the impact on the source. The increased noise in the drain environment at this operational



stage is predicted to occur during the mobilization of mud and operational of heavy equipments, and dredging activities. These impacts will be cumulative and the affected community group is the community around drains (larger than the project area). Directives of environmental management that will be done to overcome noise pollution are:

• Restrictions on working hours and traffic regulation; • Limiting the speed of the dredging material transport vehicles; and • Regular maintenance on the equipments and project vehicles.

Meanwhile, directives of environmental monitoring are:

• Measurement of noise levels at the predetermined location by using a sound level meter once every 3 months during the dredging of Cideng-Thamrin drains;

• Comparing the quality standards according to the Decree of Governor No. 551/2001 regarding noise quality standards;

• The noise monitoring result is prepared on average and compared from time to time to see the trend changing environmental quality and critical levels.

d. Sediment Quality Dredging activities of Cideng-Thamrin Drains that has important impact towards sediment quality is the physical dredging activities with the volume of dredged material for ± 168,000 m3. These dredging activities have the potential to produce heavy metals and hazardous materials contained and accumulated in river sediments. If heavy metals in this sediment were not properly managed, it can contaminate soil, ground water and seawater, where those sediments are dumped or stockpiled. Pollution will eventually have an impact on public health and the negative public perception. The intensity of arising impact will be high and lasts long. The distribution is limited at the activities location and sediment landfill (dredged material), numerous of affected human and environmental components, and cumulative. Directives of environmental management are:

• Checking the content of heavy metals in the sediment of Cideng-Thamrin Drains with heavy metal TCLP test, conducted prior to dredging activities;

• If it contains heavy metals/toxic, it will be managed as hazardous and poisonous (B3) waste according to applicable laws and regulations.

Meanwhile, the directive of environmental monitoring is to monitor B3 at every 1 km (composite) with TCLP test, prior to dredging activities. e. Solid Waste Dredging activities of Cideng-Thamrin Drains that has important impact towards waste is the physical dredging activities, dredged material separation, waste utilization and transportation of waste to landfill. Those activities will generate a number of garbage. If these wastes are not highly regarded, it will further affect the hygiene and environmental sanitation, public perception, health for surrounding community, waste separation worker and air quality.



The intensity of arising impact will be high, the distribution is limited around the activities location (± 50 m radius), several affected environmental components (hygiene and environmental sanitation, public perception, health of surrounding community, the waste separation worker and air quality), occurs during river dredging activities and it can be reversible upon the completion of the activities. Directives of Environmental Management are such as:

• Provide container and waste storage location after the separation with dredged material that is equipped with leachate reservoir and has a cover;

• Install the filter waste; • Collect waste from dredged material separation and activities of dredging workers

so they will not scattered; • Provide adequate personal protection equipments for community that involved in

waste separation from dredged material; • Accelerate the transport of waste to landfill, in cooperation with private and/or

Hygiene Office of Central Jakarta; • Supervise and place an environmental cleanliness worker at the dredging location

continuously every day during dredging of Cideng-Thamrin Drains by having a special monitoring staff.

Directives of environmental monitoring are: Waste will be taken directly from waste and mud separation, there will be a measurement, both on weight and volume for each sources. Therefore at the same time, it will calculate its density. After measuring the weight and volume, then a separation/sorting is conducted according to the constituent components based on the type of waste, organic or inorganic. The quantitative measurement of samples is done by weighing the sample waste at each sampling location and the waste volume measurements is performed by using volumetric technique. Meanwhile, the characteristic and waste composition measurement at each sampling location is arranged in 12 categories based on waste composition: Organic (%) volume and weight and Inorganic (%) volume and weight. f. Employment and Business Opportunity The dredging implementation is predicted to run for 24 months and it could absorb worker, which is an important positive impact that needs to be further developed, especially during the selection process that prioritizes the local manpower. If this is not done, then it potentially creates a derivative impact in the form of the emergence of negative perception from community (social jealousy) around the activities location. In addition, by having a dredging activities, it will create a derivative impact in the form of the emergence of new livelihoods for surrounding community who is indirectly involved with dredging, and increase the number of residents working in the informal sector around the activities location. The characteristic of impact is a positive important impact and will lasts during the dredging activities. The affected community groups include community in the surrounding urban village area or wider than area of study plan. Directive of environmental management plan is to give the surrounding communities an opportunity to work and have business at the activities location. Directive of environmental monitoring is the data collection method of employment and business opportunities that is conducted by doing interviews with the surrounding community. The data analysis method of employment and business opportunities is to



look at the number of employment and business opportunities for surrounding communities. g. Public Perception: At operational stage, the predicted arising important impact is the public perception on dredging of Cideng-Thamrin drains, either negative or positive perception of surrounding community. This public perception is a continued impact of public perception from preparation stage. The characteristic of impact is positive or negative important impact and will last during operational stage until the post-operational stage. The affected community group will be the community in the affected village along Cideng-Thamrin drains and the surrounding area or wider than the planned study area. Directive of environmental management plan is the dissemination which carried out in a transparent manner by involving local community leaders such as cleric, Village Council, and so forth. The environmental management that has been conducted is by providing opportunities for affected people so they can express opinions and aspirations through the village officer. Directives of environmental monitoring are desktop study, field study (mini survey), observation, interviews with random purposive method with the surrounding community. 6.3.3. Post-Operational Stage At this post-operational stage of Cideng-Thamrin Drains, there will be an impact to flood reduction and public perception. a. Flood Reduction Based on the prediction result, it appears that prior to dredging of Cideng-Thamrin drains, in general, it still can accommodate runoff water from surrounding catchment area. However, there are several locations which are still flooded due to lacking of capacity of connection drainage and pump capacity, and a bottleneck. With the dredging of drains, the potential for flood or overflow of drains will disappear. The existence of this cumulative impact will continuously disrupt the health of surrounding populations, so we need a mechanism to reduce the impact on the source. The increase of runoff water in drains environment on operational stage is predicted to occur because the dredging is not maximum. These impacts will be cumulative and the affected community group is the community around drains (larger than the project area). Directives of environmental management will be made to overcome the pollution of runoff water by managing the dredging properly in accordance with the planned volume and tonnage, improvement of river embankment, additional pump capacity at Jalan Thamrin, additional pump in Siantar, disassemble bottleneck at Jatibaru bridge and construction of inspection road along the Cideng-Thamrin drain. Directives of monitoring that will be performed are monitoring the water discharge and flood/puddle height, then analyze these potential runoff water in causing disturbance to the location.



b. Public Perception Impact towards the public perception can be negative and positive. Positive public perception comes from land clearing so it will be a better area near drains. Meanwhile, the negative public perception comes from demobilization of manpower, although it is estimated that the number of worker is relatively small. Based on the above description, the impact on public perception, both positive and negative, is relatively a small impact. The characteristic of impact can be positive or negative important impact and will continuously last during post-operational stage. The affected community group includes community in urban village area along Cideng-Thamrin drains and the surrounding area or wider than the planned study area. Directive of environmental management plan is the Dissemination of post-operational stage conducted in a transparent manner by involving local community leaders, such as clerics, NGOs, Village Council, and so forth. The environmental management that has been conducted is by providing opportunities to the affected communities so they can express opinions and aspirations through the village offices. Directive of environmental monitoring plan is to analyze information from the community through the hotline service and web site, observation, and interview by using purposive random method with surrounding community. 6.4. Recommendations on Environment Feasibility Based on the description of the activities plan and by taking into account the important impact evaluation, directives of environmental management and alternative selection, therefore it can be concluded that important negative impacts which will occur still can be prevented, reduced, and addressed. Meanwhile, the important positive impacts can be developed with environmental management through technological approach, socio-economic approach and institutional approach, as shown in the table below;

I. INTRODUCTION

1.1 INTRODUCTION

Flood at the capital city of Jakarta has become a National issue that has caused big financial loss

and impacted to the community life in Jakarta. In order to reduce the amount of loss and damages due

to flood, the Government of Indonesia has identified series of flood control drains, rivers and

retention basins that requires improvement urgently. This activities will reduce the flood risk and

brings direct benefits to the community who resides and works at flood-prone areas.

Government of Indonesia through the aid from World Bank plans to implement dredging and

improvement on most existing rivers and retention basins in Jakarta. That effort is done through

Jakarta Emergency Dredging Initiative-JEDI Project which is included in Jakarta Urgent Flood

Mitigation Project-JUFMP. The purpose of this project is to reduce sediments in the river and

retention basins.

Phase 2 of JEDI Project covers twelve sewers or rivers and four basins, all have been selected to be

reviewed from planning, technical design and EIA study against the entire project location. This

dredging activity must fulfill one of main objectives of this project activity, and gives benefit towards

the flood prevention attempts at the Province of DKI Jakarta. Locations that are covered in JEDI

Phase 2 are:

1. Cideng-Thamrin

2. Waduk Sunter Timur III

3. Waduk Sunter Utara

4. Waduk Sunter Selatan

5. Banjir Kanal Barat/WBC

6. Krukut – Cideng Drain

7. Kali Sunter (upper)

8. Grogol – Sekretaris

9. Lower Angke

10. Tanjungan Drain

11. Pakin – Kali Besar Jelakeng

12. Waduk Pluit

13. Kanal Drain

14. Cakung Drain

15. Muara Kali Adem CDF

16. Muara Banjir Kanal Timur/EBC/Marunda CDF

This dredging will give a positive or negative important impact towards environmental components,

whether physical, chemistry, biological, social, economic, cultural or public health. Therefore, it

requires a research on Environmental Impact Assessment (EIA).

In accordance with Decree of Head of Environmental Management Agency No. 08/2000 on Public

Involvement in the preparation process of EIA and Decree of Governor of DKI Jakarta No. 76/2001

on Operational Guidelines of Public Order and Information Transparency in EIA Process, at the

preliminary process of EIA study, it needs to conduct EIA dissemination to the community and

related stakeholders. Through this dissemination, the activities initiator expects suggestion, opinions

and responses from community as the study and research material in further EIA study.

1.2 FUNDAMENTALS OF IMPLEMENTATION

The legal basis used as the reference in the implementation of EIA Dissemination is:

1. Laws No. 32/2009 on Environment Protection and Management. 2. Government Regulations No. 27/1999 on Environmental Impact Assessment. 3. Decree of head of Environmental Management Agency No. 8/2000 on Public Involvement and

Information Transparency in Environmental Impact Assessment Process. 4. Regulation of Minister of Environment No. 8/2006 on Guidelines for EIA Preparation 5. Decree of Governor of DKI Jakarta No. 76/2001 on Operational Guidelines on Public

Involvement and Information Transparency in EIA Process. 6. Decree of Governor of DKI Jakarta No. 2863/2001 on Type of Business Plan and/or Activities

that must be completed with EIA in Jakarta

1.3 PURPOSE AND OBJECTIVES

In general, the purpose and objectives of the dissemination is to implement Decree of Head of

Environmental Management Agency No. 8/2009 and Decree of Governor of DKI Jakarta No.

76/2001. In particular, the implementation of EIA Dissemination is intended to:

1) Protect the community interest around the planned activities location from the negative impact

which might occur.

2) Ensure there is a transparency throughout the entire EIA process on the activities plan of dredging

river and retention basin in DKI Jakarta.

3) Establish an equal partnership among the concerned parties / stakeholders with the activities plan

of dredging river and retention basin in DKI Jakarta.

4) Respect all rights to gain information related to the activities plan of dredging river and retention

basin in DKI Jakarta.

1.4 BASIC PRINCIPLES OF IMPLEMENTATION

In order to get inputs which reflect the field condition, then in the implementation of EIA

dissemination, it always lies on principles of:

1) Position equality among involved parties;

2) Transparency in the decision making;

3) Solving problem in a fair and judicious manner; and

4) Coordination, communication and relationship among related parties

II. IMPLEMENTATION OF EIA DISSEMINATION

2.1 METHOD

The community involvement in EIA study is accommodated in several stages of activities. In the

preparation stage of TOR-EIA, the community involvement is performed in the form of an

opportunity to give suggestions and responses towards the activities plan.

In accordance with the Decree of Head of Environmental Management Agency No. 8/2000 and

Decree of Governor of DKI Jakarta No. 76/2001on Operational Guidelines on Public Involvement

and Information Transparency in EIA Process. The initiator made an announcement in Warta Kota

newspaper on November 7th, 2009 (attachment 1). Later, on December 8th, 2009, an EIA

Dissemination was held with method of workshop and which was involving community around the

dredging location at river and retention basins in DKI Jakarta and other stakeholders. The initiator

informed stakeholders and the affected parties, both affected directly and indirectly due to the project,

discuss the aspects and environmental impact of the project; as well as considering the view of

concerned parties in EIA study process. In order to achieve the objective of dissemination, the

initiator prepares the presentation materials that is delivered on the dissemination day (presentation

handout at attachment 2).

Moreover, to each dissemination participant, they are requested to fill in 2 questionnaires, i.e. before

and after the dissemination (attachment 3). The last step is to accept the public responses in the form

of suggestions and opinions, whether in writing or directly addressed on the EIA dissemination day,

related to several problems, needs and its values, and alternative suggestions for problem solving. All

inputs are then classified to main issues which will be covered in TOR-EIA, and there will definitely

be a deepening for those issues towards the addressed problems.

2.2 IMPLEMENTATION TIME

The first step of EIA Dissemination is started with the advertisement in Warta Kota newspaper on November 7th, 2009 (attachment 4). After 30 days from the advertisement, on December 8th, 2009, an EIA Dissemination was conducted in the form of workshop at Auditorium of Nyi Ageng Serang, Jakarta.

2.3 LOCATION OF EIA DISSEMINATION

EIA Dissemination was held at Auditorium of Nyi Ageng Serang Building at Jl. Rasuna Said Kav.

22C, Jakarta. The selection of this workshop location is based on a reason that it is relatively

reachable by all stakeholders.

2.4 PARTICIPANT

EIA Dissemination involves representative from stakeholders with an expectation that they can give

suggestion and responses towards the dredging plan of rivers and retention basins at DKI Jakarta. The

participants of EIA Dissemination were defined as follows:

1) Representative from stakeholders (Head of Urban Village along with Urban Village Council,

Head of District) which directly and indirectly are predicted to get affected;

2) Related government institutions, especially Environmental Administrative Office and Institutions

of Provincial Government, such as: Sanitation Office, Spatial Office of Province of DKI Jakarta,

and so forth;

3) Local NGOs.

The dissemination was attended with total of 116 people, consisted of: 5 people from BPLHD of

Province of DKI Jakarta, 7 people from related institutions of Province of DKI Jakarta, 4 people from

Environmental Administrative Office, 5 people from Ministry of Public Works/PMU, 3 people from

World Bank, 1 person from PPA Consultant, 10 people from the District Office, 48 people from the

Urban Village Office, 22 people from NGO and Urban Village Council, 1 person from Press and 10

people from JEDI Consultant. The whole attendance list and pictures of EIA Dissemination can be

seen at Attachment 5.

III. EIA DISSEMINATION RESULT

3.1 INPUTS AND SUGGESTIONS ON ANNOUNCEMENT BOARD INSTALLATION

Until the deadline of responses towards the announcement advertisement regarding the project plan,

there are no inputs and suggestions from the community in writing that are addressed to the initiator

or BPLHD of Province of DKI Jakarta.

3.2 QUESTIONNAIRE RESULT

Participants have filled the questionnaire by themselves that have been prepared before the dissemination started, and at the end of discussion session. There has never been any test conducted for the list of questions, so there are few participants who misunderstood or perhaps the questions were not clear enough. Below is the summary obtained from the questionnaire: • High concern from community on the project activities (90%), but low concern on EIA JEDI

Project Phase 1 (26%), EIA Phase 2 (19%) and EIA announcement in newspaper Phase 2 (26%). • Many participants were interested (>80%) to sub-projects Phase 2, with difference (“before” and

“after” dissemination) that is relatively small. • Mostly (before is 99%, after is 95%) assume that the entire project will be “very good” or “good”

for Jakarta, compared with those who assume it will be “bad” or “very bad” (before is 1%, after is 0%).

• Related to individual main issues: o There are several disagreement on opinions between “before” and “after”, especially changes

on issue from “small” impact before the dissemination to “big” impact or “very small” after the presentation and discussion.

o Odor, traffic, water quality, waste and public health, in average become the “very important” or “important” impact for more than 70% respondents.

o The smallest issue is manpower, flora and fauna, and noise; although respectively approximately 50% of respondents consider them as an “important” or “very important” impact.

• Related to the question, in general: o Almost balance between the person who chooses a longer time (night time on

weekday)/shorter time in overall, or shorter time per day/longer time in overall. o 42% of respondents consider that the waste draining location (from mud) is “good idea”; 58%

thinks as “bad idea”. o Related to environmental management and social level, it considers as sufficient:

− 42% is recorded as “using international way” − 46% is recorded as “using Indonesian way” − 12% is recorded as “low level – as long as they get approval”

• Questions related to rank on useful result

JEDI EIA/SIA considers that overall dissemination is very useful for participants and the feedback can be used as the useful information for JEDI EIA/SIA henceforth. Several approaches especially the use of questionnaire that should be adjusted further.

3.3 IMPORTANT ISSUES IN EIA DISSEMINATION

Discussion is divided into two sessions: first session is introductory from the initiator and Provincial

BPLHD, the second session is exposure of activities plan then continued by session of question and

answer between the initiator and participants that was moderated by BPLHD of Province of DKI

Jakarta.

In EIA Dissemination, the participants were actively involved in giving important inputs related to

EIA preparation, several issues that consider as important can be summarized (transcript discussion)

which implicitly provided at Attachment 4 as follows:

1) EIA Dissemination held this time will be continued with next stage, that is discussion of TOR-

EIA, EIA, Environmental Management Plan (RKL), Environmental Monitoring Plan (RPL)

which later, it will always involve the community member in its implementation. This is with

consideration that community has obligations and rights to take and give information from the

government and initiator on an activities plan.

2) Main issues that become the attention in EIA Study preparation are as follows:

• Should maintain/preserve/supervise rivers and retention basins after dredging;

• When will be the exact time to implement this dredging activity;

• Based on previous dredging experience, it is expected to restore the environment to the

normal condition upon project completion;

• Especially for Waduk Pluit and Kali Adem, conduct a dissemination partially to the local

community before implementing the activities;

• It needs a to be clearer in the dredging techniques;

• Should take note on the placement of dredged material;

• Before the dredging implementation, the contractor must coordinate with local leaders;

• Need information on hotline at project locations to accommodate reports, inputs and

suggestions from the community;

• The community needs to be involved in the project implementation and in general, they are

very supportive with this project plan.

IV. SUMMARY

Based on EIA Dissemination results and by looking at the arising issues, then several issues that

become the focus in preparation of TOR-EIA and EIA study generally can be summarized as follows:

1. Before the dredging implementation, contractor should coordinate with local leaders and related

institutions;

2. Special condition in each project location (along the river) such as settlements, merchants, and so

forth to be focused on so it will not disturb the project activities;

3. Sediment of dredged materials will be dried first prior to transport them to disposal site so it will

not be spilled;

4. Should underline the placement of dredged material;

5. Need a Public Information Center around the project location to accommodate

reports/inputs/suggestions from the community;

6. To involve the community in the project implementation and in general is very supportive with

the project plan;

7. Highly focus on the maintenance/preservation of river and retention basin upon project

completion;

8. Further clarification on project schedule.

This official report of EIA Dissemination can be read at Attachment 5.

AUDITORIUMOF NYI AGENG SERANG

JL. HR. RASUNA SAID KAV. NO. 22 C, SOUTH JAKARTA

DECEMBER 8th, 2009

10:00 Opening by MC (Ms. Profianita)

1. Chairman of the Meeting : Head of Regional Environmental Management Agency of DKI Jakarta

Ms. Ir. Peni Susanti, Dipl. Est.

2. Participant of the Meeting : The attendance list is prepared as the attachment for this MoM

3. Welcome Speech by Head of BPLHD of DKI Jakarta (Ms. Ir. Peni Susanti, Dipl. Est):

1. All Head of Urban Village to use this dissemination of dredging rivers, canals and retention basins of Phase II as good as possible.

2. Ms. Peni attended the Asia-Pacific Congress in Manila. World Bank mentioned that last year, Jakarta was flooded and the whole world knew. In Manila, they discussed the Integrated Management Jakarta Bay. However, only Jakarta has the worst river condition. Therefore, WB gave grants so the river quality will be better, and second, seek the effort on how to eliminate if not reduce the flood. WB asked all participants to assist them as the international world also assists them. Jakarta belongs to everyone. The Governor has a high commitment on this one which internationally, it is highly appreciated. If not, Jakarta is impossible getting the assistance from World Bank. Head of BPLHD expects that all Head of District, Head of Urban Village and Urban Village Council can help each other and become an environmental police cadre. It is impossible to just put the responsibility to 12 BPLHD staffs; so if someone violates the rule, please report it to the Sanitation Office or the appropriate Public Works. When the Governor, together with Coordinating Minister went down the river, they witnessed that many people lived at the riverbank and participated in polluting the river.

3. All participants should be able to disseminate this provided information on dredging activities. All participants are sanitation cadre and also a supervisor in maintaining the cleanliness of Jakarta, especially related to the dredging river in their own area.

4. Movie Presentation

The movie contained information on flood in Jakarta. It is created by the World Bank with duration of

+ 20 minutes.

This movie presents a condition and situation when flood occurred in several locations in the capital

city and the cause of the flood. Moreover, in that movie, it also contains responses from high rank

officials/experts and community regarding flood. The Governor gives a statement on the flood factor

with river full of waste as the background. The expert/high rank official gives analysis on the flood

incidence, sedimentation in the river and its management. In 2002, flood occurred in Jakarta with

total loss could reach to trillion Rupiah. The arising impact were such as diarrhea and DBD. In

addition, it also presents the watershed in Jakarta where there are 13 rivers. There is a presentation of

flood management by with retention basins completed with the pump.

Implementation of Dissemination:

Brief introduction is moderated by Drs. Ridwan Panjaitan, Msi as the moderator

The EIA JEDI Dissemination is regulated in laws, government regulation (PP), Regulation of

Environmental Minister and Decree of Governor on EIA. Input from community is highly needed for

the next step. Also presented is staff from Public Works Office and EIA Consultant to deliver the

material. All participants are expected to address important issues in this dissemination.

5. Explanation on Project by Mr. Ir. Fuadi from Public Works Office

From this movie, we can see condition of Jakarta. Our government tried to reduce flood impact, not

only from the water itself, but the community awareness who affects it. Government of Indonesia

received grant for flood management from WB by dredging river and retention basin through JEDI

program. Ministry of Public Works together with Provincial Government of DKI Jakarta also manage

East and West Banjir Canal. Ministry of Public Works and DKI will dredge the river and retention

basins which will be divided into 2 phases. First, PPC for its study and dredging phase 1 in 5

locations. Phase II, dredging the river and retention basis in 16 locations. This study must be followed

by EIA. Dredging in 16 rivers/retention basins, first is 5 locations then the remaining locations. Prior

to dredging, an EIA study is conducted and from this dissemination, it is expected to get inputs from

all participants. Therefore, it needs a dissemination, according to the applicable regulation.

In this dissemination, it is expected to get inputs from all participants, whether the project gives a

positive or negative impact. Where they dispose the dredged materials, what transportation to use,

which route to take, these are the inputs/feedbacks needed from all participants, so this project can

give advantages and minimize the loss (if any). All participants can know where the dredging will be,

so please use this time as much as possible. Closing.

A brief introduction from the moderator for the next presentation. From this presentation, we will see

the activities, where it is held and what kind of impact would there be, especially during the dredging.

6. Presentation from EIA Consultation by Mr. Ir. Purwono

He addressed his appreciation to all attendees. Introduction as a Co-Team Leader from PPA and team

leader is Mr. John Dickie. Mentioned all EIA team. Prior to EIA, it needs to hold a dissemination. For

Phase I, it was done. Now, it is the dissemination for Phase II Project. Slide was presented by Ir.

Purwono. The hand-out slides was distributed to all participants. It stated the regulation on public

involvement and transparency in EIA and the objective of dissemination. We invited Head of District,

Head of Urban Village and Urban Village Council besides the affected community due to dredging

project so they know the project activities plan. This information to be forwarded to the community at

the participant’s area.

He explained the activities plan. He presented the waste process and condition in a drainage which

shallowing the river and capacity reduction which caused flood. It is expected that with dredging, the

capacity goes back to normal. The implementing party is Ministry of Public Works together with

Provincial Government of DKI Jakarta. He presented the EIA consultant is PPA and Arkonin. The

objective of river and retention basin dredging is also presented. There is a JEDI Project with grants

from World Bank. It presented the project objective, dredging location. We straightly went to point

no. 6 as point no. 1 to 5 was included in Phase I. It said that it started from Thamrin-Cideng Drain,

started from floodgate/bridge of Kebon Kacang, behind Grand Indonesia-Jatibaru. Then one by one,

the entire location for this sub-project was mentioned, with the volume prediction of dredged

materials. The plan for temporary placement of material is eastern side of Ancol Barat which can

accommodate 12 millions meter cubic. Currently, it is in an ongoing tender process. It mentioned the

way to transport and pile the dredged material in detail. It also presented the activities stages (from

pre-operational to post-operational) in detail along with working equipments and its procedure. The

transportation of dredged material will be done at night as it passes through the main road and very

crowded. Landfill is located in eastern side of Ancol Barat.

The presentation on important impact (odor, noise, environment, water quality, public security and

order, traffic, public perception) of project and issues starting from pre-operational, operational and

post-operational in each sub-project location. He expected that all participants to address their

response.

The moderator explained that this is the time we all gave our inputs or suggestions. All participants

are aware of what would happen if dredging takes place. The participation from all participants is

very important in EIA. If there are any complaints from the resident, it should be reported to the

appropriate person so there will not be any miscommunication. The predicted activities impact and

issue. All participants must be aware of what would happen if dredging takes place. All participants

will be invited for the next EIA document presentation. The requirement to prepare EIA is Team

Leader and 2 members must have competences and has obtained certification.

7. Question and Answers with Participants started at 11:00

1. Tugino : Section Head of Public Facilities of Kelurahan Pluit, North Jakarta

Many residents at Kali Adem, but have you surveyed the environmental impact and where the

dredged material will be placed? Please do the survey with us to Kali Adem where dredged

materials are placed. Next, Kali Muara Angke sometimes overflowing so there are flood with

20cm height.

2. Wibowo : Urban Village Council of Durikepa

I am grateful that I attend the dissemination of Phase I. There is a pump project, and now

dredging of Kali Sekretaris. Lack of dissemination from Head of Project to the community, so

there is excess (??). Mayor’s Office, Village’s Office are being protested by the community. The

construction of pump infrastructure itself is lacking of its action; not really meeting the standard.

In Greenville, there is no connecting drainage, so it is still flooded. Don’t let the construction is

implemented but no focus on the access. To involve local leader such as elders in the

dissemination.

3. Suparlan : Environmentally Conscious Community Forum (Formapel) West Jakarta

There are 2 things, first is during the implementation and second is after the implementation. On

the Phase I project implementation, the operator disposed their mud sloppily so it ruined beautiful

vases, excavator ruined trees while at that moment, there was an evaluation from Adipura team.

Our difficulty is to whom we should warn them? Who will be responsible during the project

implementation? The excavator operator obviously did not care about the damage. We want

information about where to complaint. After the river is dredged, there are some affecting factors,

such as the community behavior on disposing their waste to the river. The limited landfill and

limited transporting capacity are the factor why the community (residents, industry) disposes their

waste not in the proper place. Third, how to maintain river/canal so it is still functioning after

dredging? Requesting all stakeholders to be involved, not just occasionally or maintenance is

conducted when there is a new support. The other factor is the number of resident and capacity is

imbalance.

4. Aksadani : Head of Urban Village Council of Kelurahan Kamal Muara

There is a typo. It should be: at the corner at the northern part between Tunjungan Kamal Muara

and Cengkareng drain, and there is no explanation until now.

From Menceng, Tegal Alur to the estuary, there are many houses. There are unfinished works by

Public Works Office. Dredged material for 70cm height? It gets worst during flood, the vehicle

cannot pass through. The highest water height of Kali Tanjungan is 20cm from the flood gate.

Kali was dredged for 40cm? The problem of mud disposal site. If it is disposed to Ancol Timur,

the distance is 20 KM, but if it is disposed to Kali Adem, it will be 10 KM. The volume of

dredged material is 2 millions meter cubic, where they should be disposed? Ancol’s condition is

worst. From Menceng to Kamal, many houses. Kamal Muara is a flood-prone area. In 1 month,

about 15 days they were submerged in water.

5. H. Moh. Rante S : Kelurahan Sukapura

In general, dredging is an advantageous development for all parties (community), but definitely,

there are people that feel aggrieved, although in general, they enjoy the development. This

dredging to be started from downstream to upstream because: (1) it will smoothen the water flow

and (2) local community will not claim the mud transportation as it was cleaned up/dredged

before. The mud/dredged material will be disposed to the beach to expand the land area of DKI,

which later be used for (a) recreation, (b) hotel and (c) other business. Singapore also filling their

area, even taking our area. For example is Ambon, it is a small area but expanded with filling and

dugouts to fill in “Mardika” beach. Hopefully Sukapura can enjoy it soon. Hopefully this

dredging can comes into a realization soon.

6. Eddy Suwanto : Urban Village Council of Penjaringan

The dredging problem in Waduk Pluit. The volume was 2 million meter cubic.

a) Needs to have dissemination for community around the retention basin;

b) To involve all local leaders, starting from RT and RW, Urban Village Council, Head of Urban

Village and Head of District;

c) Considering there are many building in waduk Pluit, approximately 10 thousands building

around Waduk Pluit, please handled it properly and thoroughly.

Introduction/Short Comment from Moderator:

He repeated the question from participants and their points. It is already clear in EIA document, who does

what, how to maintain the river after dredging, the distance of mud landfill, the environmental aesthetic

problem. Please address them to PMU and Consultants. The explanation from Ir. Fuadi, Ministry of

Public Works.

Other than EIA Consultant, there is also a design consultant for this dredging activity. There will be a

design so the water flows from upstream to downstream can flow smoothly. In the current condition, the

estuary blocks the water flow. The estuary is a little bit shallow, so the flow is disturbed, therefore a

dredging is done. Moreover, a river embankment will be constructed to reduce the impact towards

community during flood. Where will it be? The improvement in river flow: dredging from downstream to

upstream.

Purwono.

Many settlements constructed. We have coordinated with West and North Jakarta. We will pay attention

to Kali Adem and Pluit. We realize that in the dissemination, we need to be supported by the area so there

will not be any resistance in the community. He requested the support from all participants for the

dissemination in West and North Jakarta.

Next Questioner

1. Tegal

For Phase II, when it will be implemented? The other day, it was Tanjungan that was used to

dredge mud that was disposed to Kamal Muara. For Kali Kamal, there was an acquisition last

year, but no implementation until now.

2. Mr. Cecep Priyana from Urban Village Council of Pejagalan

Our area is separated by Kali Angke and Banjir Kanal, but it is still flooded for 50cm. Who would

be responsible for the dirt after the river dredging (mud spills and when it dried, it create dust)?

Why Kali Angke is not dredged? There is a river shallowing, grass grows on it.

3. Jarkoni from Urban Village Council of Papanggo

Need to improve the coordination. We cannot answer if the community asked. He requested that

home eviction to be included in the budget and a guideline to preserve the river after dredging.

Answer

Mr. Ir. Fuadi from Ministry of Public Works

Until now, it is just at the design stage. Next year, the dredging will start. The dredging of Kali Angke to

the estuary.

Encourage the community to make the dredging remains useful, keep the river off from waste.

Mr. Ir. Purwono.

Thank you for the alternative of Kapuk Muara.

Need community participation to monitor.

CHAPTER 1 INTRODUCTION

1.1. Purpose and Objectives of Environmental Management Plan Implementation The preparation of Environmental Management Plan (EMgP) is intended to provide guidelines for the implementation of environmental management of the dredging activity of Cideng-Thamrin drains. Matters that should be monitored are the affected or predicted to be affected matters, both positively and negatively from the activities. Environmental management is an integrated effort in the usage, arrangement, maintenance, supervision, controlling and development of environment, therefore preservation of the potential natural resource can be maintained, and pollution or environmental damage can be prevented or reduced. This report is intended to prepare an environmental management plan for dredging activities of Cideng-Thamrin drains, with purpose of: a) Establishing a basic and appropriate directive on environmental management activities

because of dredging activities of Cideng-Thamrin drains within a certain time and space by various stakeholders;

b) Managing the impact of activity on the environment component in the attempt of prevention, mitigation, control the negative impacts and develop the positive impacts.

1.2. Environmental Policy Dredging activities of Cideng-Thamrin drains have benefit to anticipate the flood that is caused by high level of sediment content due to misuse of spatial structure. Moreover, the other benefit is to restore the level of riverbed to the original level. This Environmental Management Plan (EMgP) Report can be used by the Directorate General of Human Settlements of the Republic of Indonesia, Regional Government and related agencies for the dredging plan of drainage system in DKI Jakarta. In making the policy with respect to the function of drainage in flood management, the Regional Government of DKI Jakarta, particularly the Public Works Office of DKI Jakarta can consider this EMgP, in other words:

a) Controlling the arising negative impact and developing the arising positive impacts can be used as a guideline in preparing the management plans and monitoring the impact in the future, as the guideline to overcome, minimize the arising negative impacts.

b) Changes in the ecosystem of Jakarta requires the Regional Government of DKI Jakarta and Directorate General of Human Settlements, Ministry of Public Works, RI to constantly make improvements/adjustments to policies with respects to the efforts of overcoming and minimizing the arising negative impacts, and optimizing the positive impacts so it can give greater benefit to the residents of Jakarta in general.

CHAPTER 2

ENVIRONMENTAL MANAGEMENT APPROACHES

To manage big and important impacts that have been evaluated in EIA document, several approaches are used in the environmental management which includes technology, socio-economic and institutional approach. Below are the descriptions: 2.1. Technology Approach This approach is an ordinance or efforts that technically can be done to overcome, reduce or prevent the arising negative impacts, as well as to develop the positive impact of activities, i.e.: Pre-Operational Phase

a. Managing the impact on public perception, i.e.: • A week before dredging activities is carried out, the contractor will conduct a

dissemination with more details about the action plan to the affected communities. • Accommodate suggestions and responses from the surrounding community

during the dissemination of activity plan. • Coordinate with related agencies to follow up responses, suggestions from the

community and coordinate with landowners whose land will be used as a vehicle access road.

• Install of bulletin/announcement boards regarding information on dredging activities of drains every 1 km at both sides of the drain.

• Provide facilities for an integrated information center about JEDI dredging activities that is accessible for 24 hours by the community.

• Provide care facility complaints (24-hour hotline) to receive inputs/feedbacks and complaints from surrounding communities.

• Coordinate with/approach the relevant agencies and surrounding communities.

Operational Phase: a. Managing the impact on the Ambient Air Dust Quality and Odor, i.e.:

• Transporting vehicles must pass the emission test (evidenced by the framing of a sticker).

• Placement of heavy equipments is at the waste separation locations and Temporary Disposal Site.

• Mud dredging only performs one time during the day. • Conducting mud draining and waste separation at a reachable location with the

requirements as follows: It is far from the human settlements. There is a barrier (such as zinc) as high as 3 meters. The location is wide enough for the vehicles that transport mud and waste. Clean up the waste separation/sorting location.

• Mud drained until it dry by using a container that is placed on top of deck and on top of the drain.

• Management by using the anti-toxic is not done as it will result in the continued impact.



• Once the container is fully charged, immediately close the top of truck with a tarp to avoid the spread of odor and dust.

• Stacking mud of dredged material should not be higher than 2 meters. • The period for mud storage and waste piling is 24 hours or 1 day. • Installation of barrier (such as zinc) as high as 3 meters around the location of

draining and waste separation. • Installation of signs/marks at the location of mud draining and waste separation. • Mud dredging results that had been dried is immediately transported by waterproof

dump truck (with seal) and covered with tarp to CDF Ancol every day. • Waste from separation is transported by a vehicle according to the Jakarta Sanitation

Office standard to TPST every day. • Transportation should be conducted at night (10:00 p.m. to 5:00 am). • Dredging activities should be stopped for a moment during times of worship. • Provide a janitor at the location of dredging to clean up scattered trash and mud on

the roadway around the location of river dredging and clean the tires/wheels and body of a transport vehicles, so when the vehicles left the dredging location, it is already in a clean condition.

• Require all dredging workers to wear mask. • Provide a moving water tank car on the back of a vehicle that transports mud. The

water tank car is in charge of cleaning the scattered mud along the transportation route.

• Dredging activities should be stopped for a while, if there is strong winds (> 5 knots) and if there are enough complaints about odors from the surrounding community.

• Provide a sediment trap at CDF Ancol to clean the vehicles tires, so when they leave CDF Ancol, it is already in a clean condition.

• Coordinate with/approach the authorities of the relevant agencies and surrounding communities.

b. Managing the Impact on the Traffic and Road Damage, i.e.: • Installation of traffic signs at the location of river dredging and road access to CDF

Ancol. • Installation of signs and flashing lights and the placement of officer at the time of mud

filling to the transport vehicles. • Coordinate with relevant parties (Transportation Office-Central Jakarta, Transportation

Office-North Jakarta, Public Work Office- Central Jakarta, Public Work Office-North Jakarta and traffic cop) so the number of trucks and trips do not exceed the capacity of access road of CDF Ancol.

• Transportation will be conducted at night (10:00 p.m. to 5:00 a.m. WB). • Limitation of the transport vehicles speed not exceeding 40 km/hr. • At the segment of Kebon Kacang - Jaya Building and Ministry of Religious Affairs -

Balikpapan-Siantar, it will use a floating excavator, so it will not cause any congestion on the surrounding roads.

• Place traffic control officer at the dredging location and road access of CDF Ancol. • Coordination with Transportation Office of Central Jakarta and North Jakarta, and

related urban villages (kelurahan) primarily at dredging location of Jl. Kebon Kacang



which road is relatively narrow and numerous business parking, kiosks and street vendors around the dredging location.

• Restriction of truckload of dredged materials/results not to exceed the capacity and road load. For locations along the dredged transportation route of Cideng-Thamrin, truck capacity and maximum load is 25 tons with a route: Jl. Cideng Barat/Cideng Timur-Jl. Balikpapan-Jl. Suryapranoto-Jl. Ir. H. Juanda-Jl. Pos –Jl. DR. Soetomo-Jl. Gunung Sahari-Jl. RE Martadinata.

• Contractor shall provide deposit for road improvement/maintenance to administrative government of Central Jakarta and North Jakarta, in compliance with the provisions from each administrative government, for example: Decree of Mayor of North Jakarta No. 13/2000 regarding the establishment of control team of granting the dispensation to use heavy transport vehicles/ground transportation in soil area of North Jakarta.

• Vehicles carrying mud and waste must pass KIR test. • Coordinate with/approach the relevant agencies and surrounding communities.

c. Managing the impacts on Noise Level, i.e.:

• Dredging activities should be stopped for a moment during times of worship. • Use a suitable vehicle and equipments for operation. • Use the silent generator for a water jet method and located far from settlements. • Limitation of working hours for embankment rehabilitation from 08.00 am - 05.00 pm

WIB. • Transporting mud should be performed at night (22.00 – 05.00 WIB) • Stop the activity if there are enough complaints from the public about the noise. • Coordinate with/approach the relevant agencies and surrounding communities.

d. Managing the impact on Sediment Quality, i.e.:

• Monitor hazardous and poisonous material (B3) at every 1 km (composite) with heavy metals test, prior to dredging activities.

• If it does not contain B3 material, it can be directly transported to CDF Ancol by using sealed and closed dump trucks.

• If it contains B3 material: o There will not be any dredging on that segment. o If the dredging activities still be done, dredged materials cannot be

transported to the CDF Ancol, however: A third party who has permission from the Ministry of Environment of

Indonesia should manage it. When the sediment will be used, firstly, it must obtain the utilization of

B3 permit from the Ministry of Environment of Indonesia. • Coordinate with/approach the relevant agencies and surrounding communities.

e. Managing Impact on Waste, i.e.:

• Prevent the entry of waste from upstream or other inlet to Cideng-Thamrin drains by placing trash screen at every point of entry of the flow. For further anticipation, there will be filtering waste permanently. The Public Works Office of DKI Jakarta will do waste transportation regularly.



• If the overflow of water is in average/not in extreme condition, the dredging still can be done. In the event of extreme flooding/weather, then the work will be suspended.

• Prevent the entry of waste from community activities around the Cideng-Thamrin Drain by installing prohibition signs of throwing waste in the river and law enforcement related to sanitation.

• Continuously supervise and place an environmental sanitation worker at Cideng-Thamrin Drain every day during the maintenance of river dredging.

• Clean the surface of the water from the floating waste before implementing the dredging activities.

• Conduct waste separation found in mud at a reachable location, among others: o It is far from the location of settlements. o There is a barrier (such: zinc) as high as 3 meters. o The location is wide enough for waste transport vehicles.

• The separated waste is placed in watertight containers. • Waste from dredged material is transported to the specified location. • Transportation of waste from dredged material is done by using a dump truck

according to the standard of DKI Jakarta Sanitation Office. • Coordinate with/approach the relevant agencies and surrounding communities.

f. Managing the impact of Employment and Business, i.e.:

• Utilize (prioritize) surrounding manpower in dredging activities. • Provide information about the needs of manpower to the surrounding community

through the village office. • Work with surrounding communities in waste separation. • Provide minimum wages according to UMR, education level and skills of workers. • Require contractors to include workers in the Health and Safety insurance program

(HSE). • Coordinate with/approach the relevant agencies and surrounding communities.

g. Managing impact on Public Perception, i.e.: • Accommodate suggestions and responses from the surrounding public that are

addressed at the time of dredging. • Coordinate with relevant agencies to follow up responses, suggestions from the

community. • Install of bulletin/announcement boards regarding information on dredging activities of

drains every 1 km at both sides of the drain. • Provide facilities for an integrated information center about JEDI dredging activities

that is accessible for 24 hours by the community. • Provide care facility complaints (24-hour hotline) to receive inputs/feedbacks and

complaints from surrounding communities. • Coordinate with Landscaping Service Office of Central Jakarta. • The temporary placement of dredged material should not damage the existing park

which particularly located alongside the riverbank of Jl. Cideng Barat and Cideng Timur.

• Coordinate with/approach the relevant agencies and surrounding communities.



Post-Operational Phase: a. Managing the impact on Flood Reduction, i.e.:

• Improvement of embankment with: Sheet piling: 1,470 m and parapet stone masonry wall: 1,100 m.

• Conduct dredging in the drains that goes to Cideng-Thamrin drain (Jl.. Sunda and Jl. KH Wahid Hasyim).

• The pump is placed above the flood level, so it will not be damaged when it will be used.

• Dismantle bottleneck on Jatibaru Bridge’s segment. • Perform the drain maintenance program every year to maintain the capacity of

Cideng-Thamrin drain. • Conduct capacity building training on environmental management and monitoring

related to the JEDI project to relevant agencies and community (such as: DPU DKI Jakarta, Directorate General of Human Settlements, urban village office, village council, and community leaders).

• Coordinate with/approach the relevant agencies and surrounding communities. • Repairs plant pots that is placed along the drain should there be any damages, to

conform it to the regulation. b. Managing Impact on Public Perception, i.e.:

• Restore the condition of facilities and infrastructure to its original state, if there were any damages to houses, fencing streams, bridges, utility facilities (PLN, PGN and PAM) in the form of reparation or replacement, to conform it to the applicable provision.

• Conducting the initiation of community care for the environment to maintain cleanliness of the river

• Provide an appeal to the surrounding people to maintain the condition of a river from shallowing due to waste and mud. The appeal is done whether oral or written and in coordination with relevant government authorities i.e. Urban Village, as well as in the form of an appeal board in a place that is easily visible at dredging locations.

• Perform drain maintenance program every year to maintain the carrying capacity of the Cideng-Thamrin drain.

2.2. Socio-Economic Approach This approach represents the steps taken by the initiator in overcoming the important impacts through measures based on social interaction and the role of government. These approaches include the following:

a. Prioritize local employment in accordance with their expertise and skills. b. Establish a harmonious social interaction with the surrounding community in order to

prevent the emergence of social envy. c. Provide information about development plans and management action that will be

performed. d. Accommodate suggestions, responses and complaints and consider them for further

activities e. Involve local communities to actively participate in environmental management. f. Implement the Community Development or Corporate Social Responsible (CSR) program

such as social assistance to the surrounding community such as donations, participate in



the celebration of religious holidays, Independence Day celebrations, and participate in activities of social facilities and public facilities. All of these activities tailored to the capabilities and the readiness of the initiator. Also with good relations with relevant government agencies in DKI Jakarta, in addition to opening the complaints service to accommodate suggestions, responses and complaints from the community.

2.3. Institutional Approach This approach is a coordination and cooperation effort from various agencies that is related to manage the arising important impacts, so the impact management can be done effectively and efficiently, among others:

a. To prevent disturbance to other infrastructures of activity (public utilities), it needs to have a coordination with relevant agencies (PT. PLN, PDAM) as well as law enforcement approach.

b. The monitoring to the performance of environmental management is performed by BPLHD Jakarta and relevant agencies in DKI Jakarta and Central Jakarta.

c. Report the environmental management result on a regular basis to the concerned parties (BPLHD DKI Jakarta and related institutions in DKI Jakarta).

CHAPTER I INTRODUCTION

1.1. Background of Environmental Monitoring a. Reason to Implement Environmental Monitoring Planning. The preparation of Environmental Monitoring Plan (EMtP) is intended to provide guidelines for the environmental monitoring implementation of dredging activities of Cideng-Thamrin drains. Matters that should monitored are the affected or predicted to be affected positively or negatively matters from the activities. Environmental monitoring is an integrated effort in the usage, arrangement, maintenance, supervision, controlling and development of environment, therefore preservation of the potential natural resource can be maintained, and pollution or environmental damage can be prevented or reduced. This report is intended to prepare an environmental monitoring plan for dredging activities of Cideng-Thamrin drains with purposes, such as: ♣ Put together the efforts to maintain quality and carrying capacity of the environment by

utilizing and conserving natural resources optimally. ♣ Formulate steps to manage the arising negative impacts from project activities and

develop positive impact in accordance with the applicable laws and regulations. ♣ Determine the related agencies in the environmental monitoring activities, and the

working mechanisms of environmental monitoring.

b. Objectives of Environmental Monitoring Dredging activities of Cideng-Thamrin drains have objectives:

a) Establish a basic and appropriate directive on environmental monitoring activities because of dredging activities of Cideng-Thamrin drains within a certain time and space by various stakeholders.

b) Evaluate the results of environmental management in the aspects of prevention, mitigation, and controlling negative impacts and in developing positive impacts of the dredging activities of Cideng-Thamrin drains.

c. Importance of Environmental Monitoring Preparation of EMtP document aims to inform all parties, including the Government and the community about the activities, environmental quality, environmental impact and monitoring efforts that are made to control these effects properly, completely and easily be understood/comprehended by all parties. The importance of this preparation of EMtP document is:

a) As a means to evaluate the activities plan in the management and control of negative and positive impacts which is described in the EMtP document. EMtP documents can

Introduction

be used as guideline in the preparation of management plan and monitoring environmental impacts in the future.

b) As a means to identify indicators of environmental changes that are not desired, so

that mitigation steps can be implemented effectively. c) To increase community participation in maintaining environmental sustainability.

The community can use the documents as a "social control" in order to maximize positive impacts and minimize negative impacts from dredging activities of Cideng-Thamrin drains.
