Abstract

The main objective of this research were to analyze acreage response of agricultural investments

in Jambi soybean production. Study was conducted in Jambi province using secondary data from

1986 – 2017. Acreage response functional form was used to explain and analysis problem of

acreage response of soybean production in Jambi. Study was done in 2018. A method of

measuring price expectation for analyzing acreage response is used when the influence of price

support and market phenomena varies with market conditions. It assumes that the effect of

changes in government policies because similar programs for acreage control and price support

are likely form of future policies. A method of evaluating support and acreage restriction is

developed and tested to see the impact of changing government programs. The results showed

that when the support price is much below the expected market price, the truncation effect is

negligible and the price support program has only a limited impact on acreage decisions.

Alternatively, as the support price levels, the truncation effects become larger, and the resulting

impact on acreage decisions is more pronounced.

Abstract

The livelihood strategy is fundamental in the lives of residents, including Torani fishermen as an

effort to survive or improve their standard of living. The sustainability of the Torani fishermens

livelihood pattern is related to the social formation in the mode of production (production power

and production relations) that takes place. This research aims to analyze the relationship between

the mode of production with a livelihood strategy that is carried out for the sustainability of

Torani fishermen in Takalar district. This research develops a Pospositivistic paradigm of

descriptive research through a qualitative method using a case study design. Data was collected

and analyzed according to the instructions of qualitative research through three stages of

activities, namely 1). Data reduction 2). Data exposure and 3). Conclusion and verification. The

results of the study indicate that the mode of production that takes place in the torani fishing

community is the capitalist mode of production and the non-capitalist mode of production, where

the capitalist mode of production dominates the non-capitalist mode of production. The two

modes of production provide different income results and become the basis for making a choice

of livelihood strategies. Some choices of livelihood strategies that have been carried out are

Abstract

This study was conducted at Bua Ponrang and South Larompong, Luwu, South Sulawesi in

2015. This study aims to identify the cocoa cultivation characteristics and analyze the loss of

income due to inappropriate input of fertilizer at the study sites. In this study, firstly, the data of

cultivation characteristics and economic variables (productivity, market price, mixed costs) were

collected from 112 farmers using a well-structured questionnaire. Then, the economic analysis

was carried out by using NAIL (Net Agricultural Loss Income) analysis to evaluate the loss of

income. The results showed that most of the local farmers were prone to use mixed cultivars

(M01, S1, S2, 45 BB) as entres, mixed cropping system, 3 x 3 planting distance, and inorganic

fertilizer input, and the majority of plant pests and diseases were Conomorpha cramerella, VSD,

and rotten disease. The loss of income per productivity (t/ha) in Bua Ponrang were ranging from

Rp.5,521,623 to Rp.12,360,859 respectively, while in South Larompong were ranging from

Rp.7,313,180 to 10,885,499 respectively.

Abstract

Farmers’ social is an important element in developing the future of agriculture. Especially the

perception of young farmer, it needs serious attention because they are the pioneer of agricultural

in the future. This research aimed to investigate the perception of young farmers towards their

future and also their parents’ perception towards the future of the young farmer. There are 178

households of coffee farmer involved in this research which have children who are still in

productive age and they are interviewed separately. The data analysis used Friedman test, factor

analysis, then integrated in socio-spatial. Based on the result obtained from farmers’ age, the

ability to access an information and knowledge about market became the main factor affecting

farmers’ perceptions towards the future, meanwhile education level did not show any influence.

The decision that parents decided to their children based more on social perception where

farming perceived as a low occupation in social environment although the income in a decent

category. Having a different perception with the parents, the young farmers is more optimistic in

terms of their future in developing business on agriculture sector by seeing their own potential

and agricultural resources. Based on the result, researchers concluded that the cause of different

perception affected by different age, perspective, and characteristic. It can be denied that there

will be a conflict from this difference, so the researchers suggest to both parents and children to

equate their perception, especially for the parents as a leader in taking a certain decision.

Therefore, creating a modern agricultural social environment with the business oriented in family

and community is the best option to make a same perception about future agricultural business.

human resources in rural areas, especially in terms of farmers quality and skills, are relatively not

working as expected. To reduce the level of dependence of farmers to traders, it is necessary to

strive for financial institutions that are able to provide capital needs to farmers in a fast time

without complicated procedures. Therefore farmers have alternatives to choose marketing

channels that can provide better prices.

Abstract

Smallholder plantations in South Sulawesi Province produce an average of 12.50% of Indonesia

Arabica coffee, equivalent to 20.10 thousand tons per year. In 2015 Arabica coffee produced by

community plantations in the province reached 20.35 thousand. One of the largest Arabica coffee

production centers in South Sulawesi Province is in North Toraja Regency, in 2017 it gave a

production share of 10.37% or a total production of 2.11 thousand tons. However, the current

problem in North Toraja Regency is the low purchase value of collectors who come directly to

farmers gardens and appreciate Arabica coffee of Rp. 18,000 / liter which still has epidermis, if

converted to kilograms requires around 2.1 liters, which if the total is only Rp. 36,000 / kg. This

study aims to formulate the lowest unit price policy for Arabica coffee in North Toraja Regency

which is used as a reference for the average selling price of Arabica coffee (actual price). This

research was conducted in North Toraja Regency, South Sulawesi Province using purposive

informants, which were analyzed descriptively quantitatively. The results showed that the lowest

unit price of coffee commodity can be formulated in the amount of Rp. 28,000 / liter by

increasing the price received by farmers by Rp. 10,000, by considering prices at the level of

traders and companies so that they continue to provide benefits for each marketing institution.

With this policy will have an impact on increasing the productivity and welfare of coffee farmers

so that the sustainability of coffee commodity farming in Indonesia is increasing.

Productions and utilizations of organic fertilizers originating from solid waste of super intensive

shrimp farms to reduce the amount of wastewater released to the surrounding areas and its

environmental impacts, are recommended to support both aquaculture and agriculture industries.

This study was aimed to evaluate growth of natural feed (plankton and lablab) fertilized by

organic fertilizer originating from super intensive shrimp farm and other different fertilizers.

Completely randomized design was applied in this study with four treatments and three

replications. The following treatments were urea + SP-36 + organic fertilizers originating from

intensive shrimp farm + isolated shrimp ponds bacteria ISO (A), urea + SP-36 + commercial

organic fertilizer (B), Urea + SP-36 + chicken manure fertilizer (C) and control, (urea + SP-36)

(D). The dosages of fertilizers were: urea 200 kg/ha, SP-36 100 kg/ha, and organic fertilizers

(solid waste originating from super intensive shrimp farm, commercial organic fertilizer and

chicken manure fertilizer) 2000 kg/ha. The measured variables were species composition and

abundance of phytoplankton, biomass of lablab, and water quality. The results of this study

indicated that treatments A and B resulted high in number of plankton genera, which was 19

genera, whereas treatments C and D only 10 genera. The highest mean abundance of plankter

was found in Treatment A, which was 14,571 ind/L, followed by Treatment B, 9,489 ind/L;

Treatment C was 8,717 ind/L and the lowest was found in Treatment D, 5,066 ind/L. The

dominant phytoplankton observed in this study was Oscillatoria sp. whereas the most observed

zooplankton was Branchionus sp. The mean biomass of lablab produced from solid waste

originating from super intensive shrimp farm was 4.35 g/100 cm2 which was not significantly

different (p>0.05) from Treatments B and C, yet significantly different (p<0,05) from the

Abstract

Agribusiness of cattle is an activity that integrates the development of the agricultural sector

simultaneously with the development of industrial sectors and related services in a group of

cattle industry from upstream to downstream. This study aims to determine the increase in

income of farmers through artificial insemination in agricultural businesses of cattle in the

central district of Sinjai, Regency of Sinjai. There are 100 breeders determined on purpose,

which consisted of 50 breeders of natural mating cattle and 50 breeders of artificial insemination

cattle that were interviewed to be used as data sources. The data analysis uses the income

formula and is descriptively explained and uses the artificial insemination efficiency formula.

Based on the results obtained from the sale of both natural and artificial insemination cattle, a

significant difference can be seen between the two, a natural mating cow can only be worth

millions if it is one year old, while the cattle of IB only needs a matter of months to be valued in

millions of rupees, it is due to differences in the acceleration of growth between natural mating

and the results of the IB that result in income differences between breeders of natural mating and

IB, IB breeders experience a significant increase in income compared to natural mating breeders.

The majority of the cows sold by breeders in Central Sinjai are bulls, which is quite disturbing

for breeders of natural breed cattle due to the fact that many begin to switch to IB when their

cows are lustful but do not find bulls. IB is a solution for breeders who do not find bulls, IB is

also considered more efficient because it can prevent inbreeding and lesions during mating and

the average success rate is high because only once the injection of a cow has been pregnant And,

more importantly, the resulting offspring are larger and faster growing and high selling prices.

Abstract

Potato (Solanum tuberosum L) is one of the horticultural products that receives priority for the

development of diversified food consumption, so potatoes are one of the most important food

products in the world. One type of potato grown by the people of Indonesia is the granola potato.

In terms of cultivation, potatoes are more resistant to pests or diseases. Potato granola is one of

the important plant products that have potential business opportunities, and is one of the leading

commodities in the Tombolo Pao district. The method used in this study is a qualitative and

quantitative method that includes: descriptive analysis, agricultural analysis, IFE matrix analysis

and EFE, SWOT analysis. The results of the analysis show that the condition of the potato

agribusiness system in the Tombolo Pao District still does not work optimally, due to the non-

functioning of the upstream subsystem, where the acquisition of production facilities is still

carried out individually, which causes the lack of production inputs, that is, the problem of potato

granola seeds. In the crop subsystem, potato cultivation has provided farmers with a gain of

Rp1,530 / kg with an R / C ratio of 1.25, which means that each rupee cash expense generated

will generate an income of Rp1.25. Due to the resulting R / C ratio, it is feasible to develop this

farm. In the marketing subsystem, potatoes have been marketed in Kalimantan and Sulawesi

Southeast. Prices are determined by collectors. In the downstream (processing) subsystem, not

all processed potato entrepreneurs use potatoes as raw material, which makes new potatoes sold

in fresh produce. In the service and support subsystems, with the support of agricultural

extension workers who accompany and provide information related to potato cultivation, but

from the support capital, farmers have not used the credit provided by financial institutions

because they still use Private capital. Based on the identification of internal and external factors,

several wishes are obtained to move forward and learn from the farmer groups and the

government.

Abstract

Traditional agriculture has always been taking place in rural areas. This agricultural model tends

to utilize simple technology and is in accordance with local socio-cultural conditions. The

traditional agricultural model is also the opposition of modern agriculture in the concept of a

green environment or a green earth. If modern agriculture has many negative impacts on the

environment, then traditional agriculture has many positive impacts on the lives of all earth

creatures. This paper aims to reveal the actions of farmers in managing their agricultural land

based on local knowledge. This research took place in three locations, namely: (1) Labuku

Village, Maiwa District, Enrekang Regency, (2) Ilan Batu Village, Walenrang Barat District,

Luwu Regency, (3) Segeri Village Segeri District, Pangkep Regency. The informants of this

study were farmers in the three regions. Each region has 2 informants so that the total were 6

informants. The key informants are each of the traditional leaders, and village officials. Data

collection using interview techniques, observation, and study of literature. Data analysis uses

Three-Flow techniques namely reduction, categorization, and conclusion. The results showed

that traditional farming techniques in Labuku, Ilan Batu, and Segeri Village were characterized

by rain-fed rice fields, not using chemical fertilizers as plant fertilizers, rice disease repellent,

and rat repellent but instead using betel leaves, betel nuts and lime. Even so, high-quality rice is

harvested once a year. The conclusion of this research is that traditional knowledge-based

agriculture in the research location always uses the surrounding environment resources. Such

methods directly impact on the creation of a green environment and indirectly counteract the

negative impacts of modern agriculture

Abstract

Seaweed agribusiness, especially the type of Euchema Cottoni Sp, is widely cultivated in

seawater areas, so that a seaweed agribusiness system is formed, where each of the agribusiness

subsystems are interrelated with one another. Several obstacles were encountered, including: 1)

capital is still private; 2) technology (tools, materials and ways) is still simple (traditional). 3)

low information, especially the results of research and development technology; 4) fluctuating

selling prices, 5) The availability of weather factors, and pests ,; 6) the lack of supporting

institutions for agribusiness development such as the government, financial institutions,

marketing and distribution institutions, cooperatives, formal and informal education institutions,

extension institutions, Agribusiness Research institutions, guarantee and risk management

institutions, So that there is no good and continuous collaboration between seaweed farmers and

supporting institutions. With this problem, this study discusses the Strategy for Seaweed

Agribusiness Support Subsystem Development Strategy in Marang District, Pangkep Regency as

one of the goals of developing supporting institutions from aspects strategy of supporting service

subsystem development, analyzing the development of supporting institutions, and developing

seaweed agribusiness development. Informants were selected purposively, processing data using

descriptive qualitative analysis methods in describing regional potential, SWOT analysis for the

development of supporting institutions development strategies, and development analysis using

AHP methods. The results showed that South Sulawesi Province, especially in Marang sub-

district had the potential to be developed supported by the availability of facilities and

infrastructure, land availability. The results showed that South Sulawesi Province especially in

Marang sub-district had the potential to be developed supported by the availability of facilities

and infrastructure, land availability which indicated that the supporting institutions of seaweed

agribusiness were feasible to run, after conducting an analysis, it could be concluded that the

supporting subsystems in agribusiness existed three, namely: government institutions, banking

and cooperatives. These three things must be coherent with each other so that the policies given

can benefit one another.

Abstract

Combine hasvester is a rice harvesting machine technology that was originally developed in

South Korea and Japan. Combine hasvester basically as a rice harvester machine that helps

farmers in harvesting rice. This technology is very helpful in terms of labor, time, harvest costs

and harvesting speed. Increased rice production in the province of South Sulawesi is not only

intended to meet regional needs, but it is expected that this increase can contribute to an increase

in national rice production. In Gowa Regency, that agricultural equipment and machinery

(combine harvester) has been applied to farmers to assist farmers in conducting their farming

business, rice production has also begun to increase. With the empowerment of farmers,

especially in the application of the combine harvester, the farmers become empowered and have

knowledge, so that the sustainability of increased production can be realized. Of course, the

production will also have a positive impact on the economy of farmer households that can

continue to run well in accordance with the wheels of the daily economy and meet the needs of

farmers household lives.

Abstract

The iconic symbiosis with clownfish is not the only sea anemone-fish association. Several

tropical sea anemones provide microhabitat for the Endangered (IUCN Red List) Banggai

cardinalfish Pterapogon kauderni. Microhabitat loss from declining sea anemone populations is a

serious threat to native P. kauderni populations or evolutionarily significant units (ESUs). One

measure advocated to maintain and rehabilitate these P. kauderni ESUs is to restore microhabitat

abundance. The objective of this study was to evaluate the feasibility of asexual propagation of

wild anemone broodstock with subsequent release. Two species with which P. kauderni

commonly associates (Heteractis crispa and Entacmaea quadricolor) were identified through

field surveys. Parent anemones were bisected, cutting through the centre of the oral disc.

Propagules (half anemones) were placed in empty clam shells as hard substrate. Treatments

provided different levels of protection from potential predators, in aquaria (P. kauderni

present/absent), concrete tanks (P. kauderni and Diadema urchins excluded/not excluded) or in a

net cage on natural substrate (fish and invertebrate fauna including P. kauderni and Diadema

setosum). The cut edges of sectioned anemones joined together within seconds, with wounds

typically healing in around 7 days and joins hard to see after 3-4 weeks. Growth was faster and

long-term survival higher in the net cage compared to tanks for uncovered and covered

anemones. The results indicate potential for this propagation method in the context of P.

kauderni conservation, and suggest sectioned anemones should be moved to the natural

rehabilitation areas once capable of adhering firmly to hard substrate

Abstract

Makassar, the capital city of the South Sulawesi Province. The uncontrolled of urban built up

area growth, as well as the lack implementation of Rain Water Harvesting (RWH) led to an

increase of runoff coefficient, so the abundant volume of rainfall in the rainy season directly

flows to the river and thrown into the sea. This is supported by the growth of population which

triggered the urban built up area expansion as the effect of high migration to Makassar city. Due

to this phenomena , the green open space is reduced and as coastal city which intrusion of

seawater into land make city lack of ground plain water. Although rainfall range in Makassar

City area is high, but the huge volume of rainfall not be utilized maximally yet. Some of

Makassar area suffers from flood during rainy season but citizen lacks of plain water during dry

season. Implementation of the concept of RWH in Makassar city, will be alternative solution to

reduce flood areas and can be utilized by the community for landscaping / agriculture, cleaning

activities and water amenities (fire).

Abstract

Cocoa plantations have ecological functions as carbon sinks and depositors. Cocoa absorbs CO2

during photosynthesis, then converts it to carbohydrates by storing it in the form of biomass in

roots, trees and leaves. The purpose of this study was to determine the carbon uptake of cocoa

trees and tree growers, undergrowth, necromasses, carbon uptake at the root and carbon uptake

in soils in several cocoa planting systems implemented in Bantaeng Regency, South Sulawesi.

Sampling is done by purposive sampling method with the basic consideration of the type, density

and cropping system applied. Biomass estimation is used non destructive method by measuring

diameter at breast height (DBH, 1.3 m) and height of cacao and shade plants. Carbon storage in

cocoa plants is distinguished by several cropping systems, namely K1 (monoculture harvesters)

and K2 (multistrata harvesters). The results showed that carbon reserves in Bantaeng Regency

were 32.38 tons/Ha.

Nurul Pratiwi


Abstract

NURUL PRATIWI. Determination of Salinity and Temperature at the base of the Tallo River

Estuary (guided by Mukhsan Putra Hatta and Akhmad Sumakin). In the waters of the Tallo River

there is an interaction between fresh water and sea water. This interaction is one of the influences

on the spread of salinity. Also there are driving factors such as tides that greatly affect the value

of salinity. The purpose of this study is to describe the distribution of salinity at the bottom and

how the relationship between temperature affects salinity, especially during high tide conditions.

Data was collected at the base of the Tallo River Estuary with a distance between 400m. By

using ADCP (Acoustic Doppler Current Profiler) and CTD (Conductivity Temperature Depth)

tools. The pattern of salinity distribution is illustrated by the ArcGis 10.3 The results showed an

increase in salinity found in the Muara Tallo area during high tide and low tide conditions up to a

distance of 3.6 km, as well as the close relationship between temperature and salinity which

showed directly proportional and related results. And based on water clarification, the area of the

Tallo river estuary can be categorized as mostly brackish water.

The comparison of dimethyl sulfide concentrations from the abundance of plankton

in the dry season and rainy season from two nutrient sources of Tallo freshwater

runoff and Pangkep river

University of Hasanuddin

Abstract

We determined the ratio of the concentration of dimethylsulfide (DMS) and metabolic

precursors, dimethylsulfoniumpropionate (DMSP), in water and particulate samples obtained

along the transect through the runoff of the Pangkep and Tallo rivers in the rainy season and the

dry season to the open sea. In most cases, we observed a positive correlation between the

concentration of biogenic sulfur species and salinity, especially when the concentration of sulfur

compounds was measured for chlorophyll as a measure of phytoplankton biomass. Normal

concentrations of DMS, dissolved DMSP, and particulate (intracellular) DMSP increase non-

linearly with salinity from estuaries. DMS however, is generally highest near the surface and

decreases by moving away from the euphotic zone. At the mouth of the Tallo River, runoff

dominated by surface water affects the dominance (D) of phytoplankton from the Makassar city

river flow, and the reduction of nutrients from the sea cannot be predicted. Pangkep river estuary

abundance of phytoplankton is more dominant than the genus Chaetoceros sp. The value of

phytoplankton dominance is associated with the decline of organic nutrients from river mouths,

this shows that the absorption of phytoplankton is the main surface up weeling process that is

responsible for reducing nutrients. The average value of diversity index is 1.11; 0.082 and 0.521

while the value index of diversity, water surface and dominance in the subsurface ocean that is

1.14; 0.088 and 0.55. The result of the distribution of spatial abundance of phytoplankton in the

west season and seasons east shows the level of k water surface phytoplankton in the area is

different .

Abstract

In the waters of the Tallo River there is an interaction between fresh water and sea water due to

the tidal events that greatly affect the value of salinity. This interaction is one of the influences

on the occurrence of the spread of salinity. The purpose of this study was to describe the

distribution of salinity and flow velocity that affected salinity in the Tallo Estuary area,

especially in the riverbed area during high tide and low tide conditions. Data collection was

carried out in the Tallo River Estuary area with a distance between 400 m. By using ADCP

(Acoustic Doppler Current Profiler) and CTD (Conductivity Temperature Depth). The pattern of

spreading salinity is illustrated by the ArcGis 10.3 program. The results showed an increase in

salinity found in the Muara Tallo area when tide conditions and conditions receded into the river

with a distance of 3.6 km, as well as flow velocities that affect salinity where at an increase in

flow velocity will result in increased salinity while at low tide the flow rate will result in

decreased salinity. Based on water classification, the Tallo Estuary area can be categorized as

mostly brackish water.

Abstract

Estuary is a coastal waters where the river mouth meets the sea and where fresh water mixes

with salt water from the sea. Estuary forms a transition zone between the river environment and

the marine environment. The mix of seawater with fresh water makes the estuary region unique,

with the formation of brackish water with fluctuating salinity. The purpose of this study was to

determine the distribution of salinity and temperature as well as the relationship of the effect of

temperature on salinity in the Muara River area during the highs and lows conditions. Data

retrieval is done in the Jeneberang River Estuary area with a distance between 200m points using

the ADCP (Acoustic Doppler Current Profiler) and CTD (Conductivity Temperature Depth). The

pattern of spreading salinity and temperature is described using the ArcGis 10.3 program. The

results showed an increase in salinity found in the Jeneberang estuary area during tidal

conditions and receding conditions, as well as the closeness of the relationship between

temperature and salinity which showed a directly proportional result. Based on water

clarification, the Mueberang River estuary area can be categorized as brackish water.

flora remains indicated deposition in warm climate at Early Miocene (14-9 Ma). Meanwhile,

Globorotalia truncatulinoides-foraminifera, Discoaster variabilis and Calcidiscus leptoporus-

nannofossils as taxa characteristic of slight warm condition are locally abundant. In contrast, the

younger part of deposited section at Late Miocene (5 Ma) is dominated by marker species of

medium temprature climate, particularly Discoaster challengeri, Gephyrocapsa mediterrania, G.

carribeanica and Coccolithus pelagicusnannofossils. The relative abundance of warm temprature

Abstract

An Abstract is Tallo River is the estuary of drainage channels in this area, which has the

potential to pose a threat of flooding because it is strongly influenced by tides. Floods are very

detrimental to the economic activities of the people so they need to be controlled. Flood control

is generally overcome by a sustainable drainage system. To store runoff, it is necessary to

increase the hydraulics capacity of existing infrastructure, especially rivers and drainage

channels where this usually requires additional land. Regulation Pond is a flood control facility

that can be built upstream from areas to be protected from flood hazards. then the planning

capacity of the Regulation Pond can be used to reduce flood peaks that occur in the Tallo

watershed. To overcome the flood in one part of the city of Makassar is currently in the process

of building the Nipa-Nipa Regulation Pond. This reservoir was built to reduce flooding that

occurred in the city of Makassar. Nipa Nipa Reservoir is located in the middle of the Tallo River

Basin and is crossed by two rivers, the Malarangang River and the Tallo Hulu River. The area of

the reservoir to be built covers 84 hectares. This nipa-nipa reservoir will divert water discharge

from the Tallo River, so that the impact of flooding on the 3,000 hectare land in Biringkanaya,

Tamalanrea and Tallo Districts can be prevented.

Abstract

Abstract. Heavy metals such as Cu, Pb, and Zn, have been reported to be the main contaminants

found in post-mining areas. Settling pond treatment systems have been applied to the base metal

mining area at Sangkaropi, before being discharged into the Koyan River that through the

agriculture area. This study aims to conduct an assessment of heavy metal contamination in areas

impacting base metal mining. The material tested was sediment deposition in the Koyan River

which is a sensitive indicator for monitoring contaminants in the aquatic environment. River

sediment sampling is categorized into three areas, namely the first area upstream before the

mining location, the second from the mining area to settling pond and the third area after settling

pond to the agriculture area. The heavy metal test method uses the Atomic Absorption

Spectrophotometry type Buck Scientific 205 version 3.94C. The assessment is performed based

on the value of contamination factor (Cf) to explain the process of contamination toxic

substances to the environment, Geo-accumulation Index (Igeo) to describe the enrichment of

heavy metal concentrations above the baseline level and ecological risk factors (Er). The results

of this study represent that in the first area, the assessment of Pb metals is low, Cu and Zn metals

are unpolluted to low. In the second area, the Pb metal has values classified as strongly -

extremely polluted, Cu (low - moderately polluted), and Zn (unpolluted - low) metals. In the

third area, Er values on all metals are classified as low polluted and Cf and Igeo values are

unpolluted. The results of the assessment of the distribution of heavy metals Cu, Pb, Zn will be

able to assist policies to direct land use in areas impacting mining and interdisciplinary studies to

assess environmental health impacts.

Abstract

The Study has been conducted on the distribution of heavy metal content of manganese (Mn) on

landfill in Antang Makassar. The study aims to determine the presence of heavy manganese

metal (Mn) in the landfill of Antang Makassar waste landfill. There are 4 lines namely line A

sampling points (A0, A5 and A10), line B sampling points (B0, B5 and B10), line C sampling

points (C0, C5 and C10) and line D sampling points (D0, D5 and D10) with a depth of (0-10, 10-

20 and 20-30) cm. Total samples analyzed by heavy metal elements using ICP-OES method

were 36 samples. The concentration of heavy metal manganese (Mn) in Antang landfill soil has

spread horizontally. The results of the analysis showed the presence of heavy metal content of

manganese (Mn) in the soil in the Makassar Antang waste landfill, where the samples with the

highest heavy metal content were, line A sampling points (A0, A5 and A10) each depth (0-10,

10-20 , 20-30) cm. Line C sampling point C10 at depths (0-10 and 10-20) cm, i.e. sequentially

(1660 and 1710) ppm. Line D sampling points (A0, A5 and A 0), except, at the sampling point

D0 at a depth of 20-30 cm which is 1460 ppm is still below the normal limit, which is allowed by

the Government of the Republic of Indonesia and the General of Drug and Food Control as a

pollutant inside soil. Soil pH varies from 4.82-6 and is acidic. Soil pH significantly affects the

solubility and mobility of metals, because most metals dissolve in acidic soils. The level of

pollution of heavy metal manganese (Mn) for line A, line C and line D at the sampling points

(A0, A5 and A10) at depths (0-10, 10-20 and 20-30) cm are included in the category of heavily

polluted because the concentration of heavy metals manganese (Mn) contained in the soil far

exceeds a predetermined threshold. So that necessary remediation of appropriate prevention to

prevent risks to humans and the environment.

This study aims to correlate fixed carbon using proximate analysis and calorific value analysis in

the South Sulawesi coal of the Mallawa Formation. The study was conducted at two locations,

namely in the Massenrengpulu Region of Bone Regency and Pujananting Region in Barru

Regency. The research method used is the collection of field data each using the channel

sampling method (ply by ply), which represents the lower layer, middle layer and upper layer of

coal. Then a proximate analysis is performed to obtain the fixed carbon and an analysis of the

calorific value. The results of the analysis show that, coal in the Pujananting area shows a

correlation between the percentage of fixed carbon and the calorific value has a very good

correlation with the linear regression value of 0.9994. Likewise in the Mallawa Formation coal in

the Massenrengpulu area, the correlation of fixed carbon and calorific value showed a very good

correlation with a linear regression value of 0.9998. An increase in the percentage of fixed

carbon in coal will be followed by an increase in the calorific value. This increasingly shows a

very strong correlation between fixed carbon and the calorific value of coal.

Rainwater Harvesting to Increase Freshwater Carrying Capacity On Small Island

(Study Case : Pramuka Island)

Graduate School Hasanuddin University

Abstract

After established as the Capital of Kepulauan Seribu Regency in 2003, Pramuka Island became

one of the most populous small islands with rapid population growth and increasing tourism visit

every year. However, it contributes to the high consumption of groundwater reserve as the main

freshwater resources in Pramuka Island. Furthermore, the rainwater catchment area also

decreases over the year as growing population trigger the conversion of the open area into

building, concrete pavement, and asphalt road. Therefore, rainfall infiltration is blocked and the

natural recovery process of groundwater reserve is terminated. As a result, unbalanced

freshwater supply and demand have taken place for years because the main natural supply of

freshwater in Pramuka Island are only groundwater and rainwater. Moreover, according to the

research which was conducted by Cahyadi 2013, natural freshwater carrying capacity in

Pramuka island has been overshot since there was no freshwater found in aquifer layer of

Pramuka Island in the dry season. Consequently, Rain Water Harvesting is selected to fulfill

freshwater supply in Pramuka Island since another option such as seawater desalination

installation system is not feasible economically. Rain Water Harvesting is expected to improve

freshwater resources carrying capacity in Pramuka Island by providing sufficient freshwater

supply from rainwater. The forecast of Rain Water Harvesting Implementation in Pramuka

Island for the next 30 years shows that the system can increase freshwater resources carrying

capacity in Pramuka Island into 1,22. The estimated maximum supply of freshwater that could be

provided by rainwater harvesting for the next 30 years would be applied as a recommendation in

development plan and policy to limit tourism visit to ensure the sustainability of freshwater

resource for inhabitants and ecosystem in Pramuka Island

Abstract

Characteristic of geothermal manifestation in Soppeng Regency, South Sulawesi has been

reported. The geothermal manifestation occurs as a hotspring found in five stations within

volcanic Formation in Lejja area. It was generated by magmatic activity and released to the

surface by the mean of geological structure activity. The hotspring water is mainly classified as

bicarbonate water, particularly in station I, II and III whereas station IV and V are classified as

the no dominant type. The occurrence of bicarbonate water in the research area was resulted by a

reaction of mixing between water vapor from heat sources (magmatic water) with surface water

(meteoric water) which increasing the bicarbonate ion in hot water. The no dominant type water

in station IV and V are caused by the reaction between magmatic water and meteoric water as a

heat source and the water source has experienced a large or a lot of mixing / reaction. Estimated

subsurface temperature in Lejja Hotspring ranges from 368°C to 429°C and further classified as

immature waters. It is shown from the study that the subsurface temperature of the research area

is very high and could be the potential source to be used as a geothermal power plant in the

future.

Fragmented biogas programs affect barriers to biodigester dissemination

Ibnu Budiman

Wageningen University

Abstract

The use of firewood for energy sources for cooking contributes to socio-ecological issues.

Alternatively, biogas is considered an environmental-friendly energy source generated from

waste, forest plants and other organic sources. However, until 2015, only 1.24 percent of

households utilized biogas for cooking fuel. This research aims to explore the landscape of

biogas governance in Indonesia, its fragmentation, and its consequences for biodigester

dissemination. This qualitative study found that there is fragmentation within small-medium

scale national biogas programs in Indonesia. Seven national government biogas programs have

similar governance arrangement and characteristics; scattered in different departments within the

ministry, using the grant approach and vendor, coordinating with local government, and do not

have proper training and M&E. Meanwhile, the NGO program-BIRU utilizes semi-commercial

approach; collaborating with multiple stakeholders (governments, construction partner

organizations, cooperatives, and private sectors-companies and banks); and has standardized

training and after sale services. Within those biogas programs, there are multiple barriers along

the supply chain process of biodigester dissemination (production and consumption-related to

socio-cultural issues) and governance aspects. Barriers to production and consumption relate to

the governance aspect of biogas programs. Fragmented governance affected the capability of

each program to tackle barriers in biogas digester dissemination and triggered innovation in

different biogas programs.

Abstract

One of the most widely used construction materials is concrete. Concrete technology is currently

developing, one of which is looking for alternative materials concrete forming. This research

focuses on the use of slag as a fine aggregate in concrete, especially in environments containing

sulfuric and chloride acid. Observations were made by testing compressive strength, split

strength, and flexural strength, with 171 cylindrical specimens and 27 sample beam specimens.

The test results show that the relative percentage of compressive strength of normal concrete on

H2SO4 curing against normal curing decreased 1.85% and 2.58% on HCL curing. The biggest

reduction in the percentage of concrete compressive strength was found in 30% slag substitution

with a value 8.42%, while the percentage reduction in the relative strength of the split strength

concrete is found in concrete with a slag substitution of 35% with a value 9.26%. As well as the

decrease in relative percentage of flexural strength was found in 35% slag substitution with a

value 12.84%. Although there is a decrease in each characteristic of concrete, slag material can

be used as a constituent for concrete under environmental conditions of sulfuric acid and chloride

acid.

Abstract

The presence of slag as a result of waste from steel production annually increases. Researchers

and environmentalists are very concerned to overcome this problem. Currently steel slag has

been studied as a substitute for concrete compilers. The focus of this research is to utilize steel

slag as a constituent of porous concrete in direct contact with acidic regions, in this case sulfuric

acid and chloride. This test was carried out using 243 samples in testing the compressive

strength, tensile strength and pore volume of concrete. Content of steel slag used is 0%, 50% and

80%. In the compressive strength test results for normal curing, sulfate curing and chloride

curing showed an increase of 6.49%, 5.71%, 8.28% in the 50% slag content and 10.81%,

10.29%, 17.20% in the 80% slag content . Then in the tensile strength test showed an increase of

7% to 11% in the 50% slag content and 16% to 17% in the 80% slag content. As for the pore

volume, the value is in range from 17% to 19%. These results indicate that slag can be used as a

substitute for aggregate on porous concrete with compressive strength ranging from 10 MPa to

19 MPa.

Department of Geology Engineering, Hasanuddin University, Makassar

Abstract

As demand on energy is growing while the resources is limited, alternative sources of renewable

energy is becoming popular. Small-scale hydropower systems or known as hydropower plant are

one of prominent source of renewable energy due to the economic competitiveness and

availability. The plant utilizes the power generated by the river flow to generate the electricity.

The Langkemme River is one of the major rivers in Soppeng Regency, South Sulawesi Province.

We evaluated situation and condition of Langkemme River in order to determine the potential for

hydropower assessment as a hydropower plant. Based on the evaluation, the topographical aspect

and the existence of permanent waters show the possibility to install the mini hydropower power

(MHP) plant on the river. From the mainstay discharge analysis using probability of 40%, the

plant is designed to have a total head as 64 m and discharge is about 5.58 meters cubic per

second (m3/sec). The production of energy is estimated as 3 MW annually. Based on the

discharge and head of the MHP point plan the type of turbine ideal for MHP plans is the Francis

turbine type.

Abstract

Energy farces an important role in shaping civilization as a major input from various sectors of

life. For Indonesia, the management and utilization of energy will determine the likely existence

as a nation forward in the future. This research used a quantitative methodology which is the

chosen method is system dynamic simulation. The system dynamics model is the shape and

energy utilization in Indonesia to achieve a degree of energy security with complex variables

covering economic, social and environmental as well. The model simulation investigates the

implications of the use of fuel to the economy and how to find a model of low-carbon energy

sustainability in the energy mix policy in Indonesia. The model explores the relationship between

population, fuel consumption, fuel production, fuel import, and emissions resulting from the use

of fuel. This model will be used as the basis for the simulation scenario of Business As

Usual (Base case) so that the visible trend of each variable and how interventions should be

done. The interventions that are chosen namely structural intervention where included gas and

geothermal as the additional energy resources. Then, a Hypothesis that would be tested in this

research is the reduction of CO2 emission and fossil fuel import as the feedback of energy mix

policy. The result shows that mix energy policy can reduce the CO2 emission at least 9% on

average along the simulation period. On the other hand, the import of fossil fuel import can be

reduced averagely by up to 27%. Therefore, the mix energy policy is strongly feasible to be

implemented and developed in the future.

Abstract

Acid mine drainage (AMD) contains high concentration of various heavy metals and have low

pH levels. In this study, the comparison between the use of natural zeolite and synthesized

zeolite for Cu2+ removal in AMD was conducted. The adsorbent of natural zeolite was prepared

through a chemical activating method by adding NaOH. While, synthesized zeolite was prepared

from coal fly ash using a two-step method, fusion and hydrothermal process. The AMD used in

this study was artificial designed with the concentration of Cu2+ 100 ppm and pH ± 3. The

adsorption experiment was carried out using batch method to observe the influential parameters

such as adsorbent dosage, contact time, adsorbent isotherms and kinetics. The result from this

study is expected to provide better alternative adsorbent between natural zeolite and synthesized

zeolite for heavy metal removal in waste water. Furthermore, both natural zeolite and

synthesized zeolite have a great potential as a sustainable and economical material for heavy

metal removal in waste water.

Value of Concrete Compressive Strength with Variation of Candlenut Shell Applicated

to plate on a Non-destructive Test Using UPV

Nasruddin, Victor Sampebulu, Pratiwi Mushar


Abstract

Concrete began to use substitute materials to reduce the brittle nature. Substitution material is

material that can replace concrete material both coarse aggregate, fine aggregate, and cement

with other materials, such as Portland cement with steel slag, broken stone (coarse aggregate)

with pumice and other stones. One of the benefits of the concrete material substitution method is

that it can use organic waste. Organic waste can be in the form of residual production or usage,

one of which is the candlenut shell which is a waste of candlenut The candlenut shell is a new

potential that can be developed and utilized even greater. Of course It can increase the economic

value of the candlenut shell which has only been known as a waste material from the candlenut.

The composition of the candlenut shells are CaO, SiO2, Al2O3, MgO, H2O, Fe2O3. When all

reacts, there will be residual SiO2 that has not yet reacted to form a silica derivative reaction

with CSH-2 gel resulting in a denser CSH-3 gel, which will increase the cement paste and

aggregate. The purpose of this discussion is to determine the compressive strength value of

candlenut shell concrete at 0% and 30% variation on the plates using Ultrasonic Pulse Velocity

(UPV) at 28 days. The method used is experimental by testing samples / specimens in the form

of reinforced plate size of 50cmx25cmx12cm with wet curing and dry curing methods with a

variation in age of 28 days. Concrete compressive strength testing is done using UPV tools The

results of this discussion are the compressive strength of 30% candlenut shell variations on the

application of the plate shows that the quality of the concrete produced in the wet curing reaches

18 MPa or equivalent to the quality of the K 225 concrete and the dry curing is only 14 MPa or

equivalent to the quality of K175, while the variation Candlenut shells 0% (normal concrete)

reach 28 MPa on wet curing and 24 MPa on dry curing. This shows that the plate with a variation

of 30% candlenut shells are still able to achieve concrete quality II for use in structural work.

Abstract

This paper presents the voltage stability analysis assessment of the Southern Sulawesi power

system in Indonesia for the year 2020, considering the load increase every year, the addition of

new power plants as well as the large additional load of smelter industries in the Bantaeng

Regency. The voltage stability method used in this paper is the modal analysis method. Modal

analysis method uses the Jacobian reduction matrix resulting from the Newton-Raphson power

flow analysis. Modal analysis produces eigenvalues for each load bus in the system. The bus

with the smallest eigenvalue becomes the focus in determining the stability of the system. Then

bus participation factor is determined to obtain the most influential bus to improve the stability.

The results of this study confirm that by 2020, the Southern Sulawesi power system will be in a

stable condition, with the smallest eigenvalue of 5.8 in bus Pare-Pare while bus Barru has the

highest bus participation factor.

price stabilization. Supply chain’s success can be seen from the level of performance.

Performance measurement is needed as an approach in order to optimize supply chain networks.

The research aims to examine the structure and performance of cayenne pepper supply chain.

The study was conducted in Gorontalo and was using survey methods. Data analysis was using

descriptive and marketing efficiency analysis. The results showed 1) The structure of the

cayenne pepper supply chain in Gorontalo Province consists of seven distribution channels. Sale

of cayenne pepper by farmers through collectors (40 percent), wholesalers (26.67 percent),

market traiders (10 percent), and retailers (23.33 percent). The primary members of the cayenne

supply chain consist of farmers, collectors, wholesalers, out-of-town traders, market traders,

retailers, consumers and agroindustries. The secondary members are farm shops, banks,

transportation service providers, the Agriculture Service and information media. 2) The most

efficient distribution channel is channel six because the smallest marketing efficiency value is

3.17 percent. The cayenne pepper’s market in Gorontalo runs inefficient because it has a price

transmission elasticity value of 1.11 (Et> 1). It means the rate of change in prices at the

Abstract

This study refers to the new public management paradigm so that management approaches in

private organizations are used in public organizations. This study is to confirm the relationship of

leadership with the motivation of public service, then the motivation of public service to the

quality of public service and job satisfaction of the State civil service (ASN). This is done

because there are differences between the results of research in Europe - America, and Asia,

especially in Indonesia about the relationship between public service motivation and the quality

of public services. On the other hand, it is found that leadership does not affect the quality of

public services directly but there is a strong correlation with the motivation of public service

delivery. This study uses a quantitative approach with SEM-AMOS analysis tool version 23. The

population in this study is all ASNs in Bantaeng Regency with a planned sample target of 397

respondents consisting of 173 echelons 1-3, echelon 4 totaling 74 respondents (10% of the

population), and staff of 151 respondents (10% of the population). However, of the 397

questionnaires distributed, only 369 questionnaires were returned and could be analyzed, while

28 respondents did not return within the specified time limit (4 weeks after being distributed).

The results showed that public service motivation became a full mediator between leadership and

quality of public service and ASN job satisfaction. Good leadership will increase the motivation

of public services which will further improve the quality of public services and ASN job

satisfaction..

Abstract

Waste tire is one of the largest waste contributors. Due to the abundant amount of waste tires that

would require the proper way to utilize waste tires as an aggregate replacement in concrete.

Crumb rubber is a fiber-shaped material, which is produced from shred or scrap of post-used

tires from trucks. Tire Chips is a material which consists of small pieces of waste rubber tires.

This study explores the ameliorative effects of rubber particles on some properties of concrete.

The objectives of this work is to present the mechanical properties of concrete (compressive

strength, modulus of elasticity and split tensile strength) with variations of crumb rubber + tire

chips 0%, 10%, 20% and 30% on fine and coarse aggregate volumes. Two types of rubber

particles (crumb rubber and tire chips) have been used in the rubberized concrete mixtures

replacing partially natural aggregates. Cylinder-shaped test object with 100 mm in diameter and

200 mm in length. Compressive strength testing was conducted at 3, 14 and 28 days. While the

modulus of elasticity and split tensile strength were tested at 28 days. The results showed that the

weight of the concrete volume decreased by 3.5% in each addition of 10% crumb rubber + tire

chips. Compressive strength and split tensile strength decreased with increasing the number of

crumb rubber + tire chips in concrete. The decrease in compressive strength was 24% on the

addition of up to 10% crumb rubber + tire chips, while the split tensile strength decreased by

16%. Adding more than 10% of crumb rubber + tire chips to fine and coarse aggregate volumes

is not recommended.

Abstract

Pervaporation process is currently applied for brine water desalination. This high water salt

content may impacts to the environmental if it is not treated well. This paper demonstrates the

performance of organo-silica membrane to produce potable water treated from brine water.

Organo-silica membrane was employed by applying sol gel process for 3 hours using tetra

orthosilicate (TEOS) as main precursor as well as dual catalyzed (organo catalyst/citric acid) and

base (ammonia) on reflux temperature of 0℃. The molar ratios were 1:38:0.0007:5:003 for

TEOS:EtOH:Citric Acid:H2O:NH3. The citric acid was chosen as carbon source to increase the

carbon chains in the silica matrices. It was found that the water flux was increased as the feed

temperature also increased from 40℃. Organo-silica membrane was tested in various artificial

brine water (7.5-15 wt% NaCl) operated at 40 and 60 ℃ as feed temperatures with the water flux

from 1.27 to 1.55 kg.m2.h-1with excellent salt rejection of >90%.

Doctoral Program of Civil Engineering, Hasanuddin University

Abstract

This research study discusses the modulus of elasticity of concrete using abaca fibers. The

addition of abaca fiber to concrete mix is done with the composition of abaca fiber 0% (normal

concrete), 0.15%, 0.20%, 0.25% with a fiber length of 50 mm. Concrete cylindrical specimens

(100 mm x 200 mm) with each variation of 3 cylinders with a total of 12 specimens tested after

the specimens reached 28 days in a Universal Testing Machine (UTM) and evaluated through the

ASTM standard in testing concrete compressive strength. Concrete compressive strength test

results with variations in length of 50 mm with a fiber volume of 0.15% produces an elastic

modulus of 23057.14 MPa. For a volume of 0.20% the modulus of elasticity is 19575.44 MPa.

Then for the fiber volume of 0.25% the modulus of elasticity is 17104.90. Normal concrete

modulus value 20058 Mpa. From these results it can be concluded that the more fiber volume,

the smaller the modulus of elasticity. The modulus of elasticity of abaca fiber concrete with a

fiber length of 50 mm and a fiber volume of 0.15% is the best and gives an increase of 14.96% to

normal concrete.

Abstract

Exploration of mineral resources requires support from geophysical methods to describe the

subsurface conditions of an area identified as containing potential minerals. Inaccuracies in the

application of methods in geophysics can result in losses caused by the calculation of reserves

from deposit models that are less precise. This research aims to optimize the performance of iron

ore exploration methods that integrate the geoelectrical with the geomagnetic method. The study

was conducted in the Ogololo Sub-District, Sojol District, Donggala Regency, Central Sulawesi.

In this area, exploration has been carried out the geoelectrical method which results in

overlapping values between the host rock granodiorite with iron ore respectively 685.7 -

7671.1Ωm and 170 - 1146Ωm. Simulation of the geoelectrical method with two-line and

geomagnetic by making a test pit to optimize the interpretation of the results of the two methods.

Abstract

Glass Fiber Reinforced Polymer (GFRP) is a composite material that is lightweight, easy to

apply, low-cost installation and maintenance, thus becoming material selection for retrofitting

reinforced concrete (RC) structure. This study aims to analyze the shear capacity of reinforced

concrete beams after initial cracked, which is retrofit with GFRP sheets in the pedestal shear

area. Six RC beams with dimensions of 15 cm x 35 cm x 300 cm were tested with a monotonic

load, consisting of 2 normal beam (BN), 2 RC beams retrofitting with GFRP strips (BGS) and 2

RC beams strengthened in all the shear zones with GFRP (BGF). The results showed that an

increase in ultimate load on the beams retrofit with GFRP, ie 3.13% of BGS and 6.25% in the

BGF. Retrofitting with GFRP sheet on RC beam shear area is strongly influenced by the extent

of GFRP sheets used (Afv). The change in the area of GFRP from BGS with Afv = 780 mm to

BGF with Afv = 1105 mm, is able to increase the beam shear capacity by 10.63%. From the

calculation, the beam shear capacity increased by 58% in BGS and 74.5% in BGF beams.

P Taba, N Shintadevi and M Zakir


Abstract

Wastewater resulted from textile dyeing is an enormous pollutant around the world. Therefore,

the existence of dyes, such as brilliant scarlet, in the water environment have to be removed.

Mesoporous silica (MCM-48) was used to remove brilliant scarlet through adsorption process.

MCM-48 was hydrothermally prepaired using co-surfactant of CTAB and Triton X-100 as a

template. After being synthesized, the material was washed once and twice with HCl-etanol to

remove surfactants used. Fourier Transform Infra-Red (FT-IR) and X-ray Diffraction (XRD)

were methods utilized to characterize MCM-48 materials. We studied the ability of washed

MCM-48 materials to remove brilliant scarlet from aqueous media with a variation of contact

time, pH and concentration. A UV-Vis Spectrophotometer was an instrument used for measuring

the concentration of brilliant scarlet after adsorption at a wavelength of 505 nm. The adsorption

isotherms of brilliant scarlet by washed MCM-48 materials were studied using Langmuir and

Freundlich models. It was found that the optimum time adsorption of brilliant scarlet by MCM-

48 washed once were 60 min, whereas those by MCM-48 washed twice were 60 min. The

optimum pH adsorption of the dye by MCM-48 washed once were 6, whereas those by MCM-48

washed twice were 5. The adsorption of brilliant scarlet by MCM-48 washed once and twice

obeyed the Langmuir model with the adsorption capacity of 62.5 mg/g and 17.53 mg/g,

respectively.

Abstract

This study uses a library approach and field research. The library approach is carried out by

reading theories related to land values from the literature study and used to obtain secondary

data. Meanwhile, field research was carried out by observation to find out and document land use

in the city of Makassar. The analytical method used is descriptive quantitative and qualitative to

describe the land value of the distance between Makassar City and land use. Besides, spatial

analysis is also used to interpret the land value of Makassar City based on the Bid-Rent Curve in

the form of maps of distance and land use. Moreover, correlation analysis is used to determine

the relationship between distance and land use to land value. The results of the study through the

analysis stages above show the value of land in the Makassar City is influenced by distance,

where the closer to the city center the higher the land value and the farther from the city center,

the lower the land value. Also, land use also affects the land value of Makassar City, wherein this

study, the most critical land use is commercial land. This shows that there are conditions in

accordance with the theory of Rent-Bid Curve.

Abstract

The Light Weight Deflectometer (LWD) is a portable device that measures the onsite dynamic or

resilient modulus (Evd) of subgrade soils and pavements. However, this method is time-

consuming. A light-weight deflectometer (LWD) developed for evaluation of surface stiffness

may be employed to estimate the degree of compaction. The application of LWD technology to

compacted asphalt layers have been combined with nondestructive testing (NDT) devices to

better characterize the stiffness parameters. The areas identified as less-compacted are common

candidates for performing the NDT spot tests. In this study, the following tests were performed

on a asphalt layer by field and laboratory LWD test. Correlation of stiffnes parameters of asphalt

layer (deflection (D0), surface modulus (E) and stress (τ)) field and laboratory LWD was

investigated. It was found that there are relevant correlations between the stiffnes parameters of

field and laboratory LWD. When these correlations are known, laboratory LWD test can be an

alternative for indirectly evaluating of stiffnes parametrs for asphalt layers. The proposed

correlation was validated with independent data from other studies reported in the literature.

Keywords: stiffnes parameters, LWD, NDT

University

Abstract

Sungkai wood (Peronema canescens Jack) is one of prominent materials used for production of

furniture and other decorative elements in Kalimantan and Sumatra due to its beautiful fiber and

color, and also its fairly smooth texture. Since of massive production, the waste resulted from the

processing of sungkai wood are very abundant. Utilization of sawdust or wood shavings of

sungkai still generates a relatively low value. In order to increase the value of sawdust and wood

shavings of sungkai, this research was aimed to identify the characteristics and performance of

bio-briquette produced from the sawdust and wood shaving of sungkai. This research was

performed by evaluating the characteristics and performance of bio-briquettes produced from

three concentrations (10%, 15%, and 20%) of glue material made from tapioca starch. The

results show that, except of the volatile matter, all parameters of the characteristics and

performance of the tested briquettes comply with the Indonesian National Standard (SNI) of

briquette product. The characteristics and performance of the tested briquettes at the lowest

levels are follows: water content (4.52%; SNI: max 8%), ash content (4.36%; SNI: max: 8%),

volatile matter (42%; SNI max: 15%), density (0.46 g/cm3; SNI: 0.45-0.85 g/cm3), combustion

time (0.14 g/min), ignition time (2.5 second/g), and calorific value (5.889 kcal/kg; SNI: min

5000 kcal/kg). It requires optimization on the carbonization process in order to reduce the

volatile matter.

Abstract

Eucheuma spinosum is one of seaweed species that can be found abundantly in Takalar Regency.

The biomass of this seaweed has been used to remove Mn(II) ion from the aqueous solution via

the adsorption process using E.spinosum. The adsorption of Mn(II) ion was studied in various

contact time, pH and concentration. An Atomic Absorption Spectrophotometer (AAS) was an

instrument used to determine the amount of ion before and after adsorption. Langmuir and

Freundlich equations were used to study the adsorption isotherms of the ion. The results showed

that the optimum time obtained was 20 minutes and the optimum pH was 4. The Freundlich

isotherm fitted the adsorption of ion Mn(II) using E. spinosum with the capacity (Qo) of 9.07

mg/g. The functional group involved in biosorption of Mn(II) metal ions was hydroxyl (-OH)

groups.
