This research aims to assess air quality status in the urban area of Jakarta and
evaluate the effect of traffic emissions control of selected air pollutants by
employing a Gaussian-plume dispersion model developed in Delphi. Sources of
air pollutants were divided into point, line, and area sources representing three
contributing sectors, i.e. industry, transport, and household. Input data for the
model was obtained from the government statistics and industrial and traffic
surveys conducted in other previous studies. Improvement of the model run-time
was done by developing a parallel implementation coded in a data-parallel
approach. The dispersion model performed reasonably in estimating the
concentrations of SO2 and NOx. Testing of the model resulted in the relative
standard errors of estimates of below 50% indicating the model could be
reproducible. However, the simulation of PM10 concentration resulted in
underestimation. The cause for this was the exclusion of other significant
sources of PM10 beside three contributing source categories under study.
iii
Prediction of future emissions using the 2002 emission data and socio-economic
factors which affect air quality revealed that the emissions of SO2, NOx, and
PM10 would increase by a factor of 1.64, 1.48, and 1.64, respectively in 2010 if
control of the pollutants emissions was not taken. Similarly, simulation of future
air quality under business-as-usual scenario resulted in increased pollutant
concentrations. The number of grids exceeding the annual NOx ambient standard
in 2010 was twice the number of grids exceeding the standard in 2002. Under
the scenario with control measures, the concentrations of pollutants, particularly
the transport-contributed PM10 were reduced by 44%. The reduction of PM10
concentration was a result of simulated implementation of vehicle inspection and
maintenance. Updating the emissions inventory to include other pollutant
contributing sources, and continued improvement of the dispersion model to fit
the best conditions of the urban area are suggested.

Kajian ini bertujuan untuk menilai tahap kualiti udara di sekitar bandaraya
Jakarta serta penilaian implikasi kawalan pelepasan pencemar udara trafik
dengan penggunaan model dispersi Gaussian yang dibangunkan oleh Delphi.
Sumber bahan pencemar udara telah di bahagikan kepada sumber titik, garisan
dan kawasan mewakili tiga sektor penyumbang iaitu, industri, pengangkutan dan
rumah kediaman. Data yang digunakan untuk model ini diperolehi dari statistic
kerajaan dan kajiselidik industri dan trafik beberapa kajian sebelum ini.
Peningkatan waktu simulasi model telah dilakukan dengan pembinaan kod
implementasi sejajar dalam pendekatan data sejajar. Pencapaian model dispersi
untuk menganggar kepekatan SO2 dan NOx adalah memuaskan. Hasil ujian ke
atas model ini pula menghasilkan sisihan lazim di bawah 50% dan ini
menunjukkan model ini boleh diterima. Walau bagaimanapun, simulasi
kepekatan PM10 menghasilkan keputusan kurang dari jangkaan. Ia adalah
v
vi
berpunca dari terkeluarnya sumber penyumbang PM10 yang lain selain dari tiga
kategori sumber pencemar yang dikaji.
Ramalan pelepasan pencemar masa hadapan dengan menggunakan data
pelepasan dan faktor sosio-ekonomi yang mendatangkan kesan pada kualiti
udara mendapati bahawa pelepasan SO2, NOx dan PM10 meningkat masing-
masing pada faktor 1.64, 1.48, dan 1.64 pada tahun 2010 sekiranya tidak ada
kawalan pada pelepasan pencemar ini. Pada keadaan yang sama, simulasi kualiti
udara masa hadapan pada senario ’perniagaan seperti biasa’ masih menunjukkan
peningkatan kepekatan pencemar. Bilangan grid melampaui standard ambien
NOx tahunan pada tahun 2010 iaitu dua kali ganda bilangan grid melampaui
standard tahun 2002. Di bawah senario dimana adanya langkah-langkah
kawalan, kepekatan pencemar, terutamanya pelepasan PM10 berpunca dari
pengangkutan, menurun sebanyak 44 %. Penurunan kepekatan PM10 adalah
hasil dari implementasi pemeriksaan dan penjagaan kenderaan. Adalah
dicadangkan untuk masa-masa hadapan, inventori pelepasan pencemar perlulah
merangkumi sumber-sumber penyumbang pencemar yang lain disamping
pembaikan beterusan pada model dispersi bersesuaian dengan keadaan yang
terbaik di kawasan bandaraya.

CHAPTER 1
INTRODUCTION
1.1 Framing the Problem
Road transport is a significant source of air pollution in urban centers (Johansson, 1995;
Chin, 1996). The impact of its exhaust emissions on human health and the environment
has raised much concern worldwide. Road transport, like any other modes of transport
has been partly responsible for greater atmospheric impacts such as acid deposition,
stratospheric ozone depletion, and climate change (Colville et al, 2001). To date, urban
traffic air pollution continues to be the focus of many air quality reviews and studies
despite the growing interest shown in global air pollution issues over the last decade.
For many years efforts to reduce traffic air pollution have been made through various
control measures including the introduction of vehicle technology, improvement of
transport system and fuel quality. As a result, traffic emissions have been reduced
substantially and some countries, mostly developed countries, reported that their
nation’s urban air quality has been improved (U.S.EPA, 2002; European Environment
Agency, 2005). In developing countries, however, with accelerating urban growth likely
to cause great increase in car ownership and use, efforts to reduce traffic emissions
remain to be seen. The challenge for the authority will be whether to act upon control
measures now to prevent air quality from getting more severe in the future or to delay
the implementation further until the damage costs in health, productivity, and economy
become enormous.
Many developing countries have developed their own air quality policy and strategy
based on their needs for improved air quality and relative findings of the status of air
quality and level of emissions. In many cases, the common strategy is often derived
from other countries’ experience, which has been proved to be successful. While it is not
necessary for a developing country to start from “the scratch” in finding what control
options work best for the country, the adoption should be done in a careful manner
because a control measure is country-specific. It may work in a certain country but may
not work in other country or may require modification to make it workable.
Indonesia, for example, first embarked its air pollution agenda in 1992 with the issuance
of “Blue Sky” program aimed at reducing air pollution in target provinces. Air quality-
related regulations have been revised or newly issued since then, including the revision
of the national ambient standard and the establishment and continued improvement of
emissions standards for both mobile and stationary sources. Control measures for traffic-
related emissions as stated in the program provisions, which are also in line with
recommendations from previous foreign-funded studies include emission regulations
through inspection and maintenance, phase-out of leaded gasoline, reduction of sulfur
content in diesel fuel, introduction of clean vehicle technology and use of smokeless oil
for two-stroke vehicles (Shah et al, 1997; Japan International Cooperation Agency –
JICA and Environmental Impact Control Agency – BAPEDAL, 1997a).
Despite the availability of regulatory instruments and proposed action plans for
Indonesia, implementation has not begun until today. Lacks of public and political wills
are the major factor, which contributes to the implementation failure of many
1.2
regulations. Provisions with regard to institutional resources, technical procedures, and
detailed administration of the regulations are not clearly defined. Unclear lines of
authority and responsibility of government agencies have often attributed to the delay of
the formulation of these implementing provisions (D. Kuper, personal communication,
October 2, 1996). Other shortcomings, in general, include lack of control and law
enforcement and shortage of well-trained personnel (Shah et al, 1997).
The newly enacted Regional Autonomy Law No. 22/1999 that stipulates in its provisions
an extended transfer of environmental policy resources and regulatory authority from the
central government to local governments is significant for the interest of air pollution
control efforts. Some areas of many environmental problems will be addressed by local
governments. Such transfer would pose a potentially formidable test for both the local
government and the public as they become much closer to the real problem and are more
challenged to tackle the problem. Public participation is central that will help the local
government to move forward to formulate and execute its action plans without further
delay (Shah, 2004).
The Provincial Government of Jakarta, in this regard, has taken initiative and advanced
into setting up a coordinating body that will oversee the implementation of emission
regulations in the Province of Jakarta. The approach is directed towards achieving air
quality objectives (air quality standards) and economic objectives (reduction of damage
costs) by implementing cost-effective air pollution control measures in line with the
national pollution control strategy. Road transport is being the target source of control.
Through active role of advocacy groups and other interest groups in Jakarta, air
