Abstract

Air pollution from vehicle emission becomes a major problem in urban areas, including Jakarta, Indonesia. This vehicle emission worsening ambient air concentration because of increasingly use of diesel engine for urban transportation, which exhaust particulate matter. This pollutan pose adverse health effect especially resparatory problems and premature mortality. This paper presents a model for estimating the level of pollution and the impact of that pollution on human health. An air quality model is developed using Gaussian model for urban area and the social-economic impact are estimated using Dose Response function. Simulation of the model shows a dynamic model is a powerfull tool for estimating the pollution level and the impact of the pollution. The result of the simulation can be used as basic information for decision makers to design some environmental policies for reducing the pollution level from vehicles emission.

Abstract

Dioxin/furan is one of the persistent organic pollutants (POPs) that the government and public in Indonesia has not taken care of, as there is currently no policy on reducing dioxin/furan emission, even according to previous research dioxin/furan emission has already high. Steel industries produce dioxin/furan emission that will give negative impact to the people (cancer and death) and environment. The objective of this research was to estimate dioxin/furan emission and to determine factors that influence dioxin/furan emission concentration on the air, especially from steels industries. Methods employed in this research used emission factors to estimate dioxin/furan emission and Gaussian dispersion modeling to estimate emission concentration. The result showed that dioxin/furan emission is 9,38-13,54 gTEQ and it has to be reduced. Production is main factor to contribute dioxin/furan emission to the air. Besides that, emission concentration also depends on temperature, wind speed, height of stacks and radius from the site to the recipient. The conclusion of the research is dioxin/furan emission should be reduced, by means of first or second treatment.

Abstract

The aim of this research is to estimate the value of health degradation caused by nitrogen oxide (NOx) gas as one of the air pollutions in Jakarta Province. The economic growth in urban area may affect lifestyle which will increase the energy demand. Fossil fuel as the main energy emitting some gases to the ambient, one of them is NOx gas.  In this research analysis of factors that influenced NOx ambient concentration is based on the socials, economics, and meteorological data from Indonesia Statistics Center (BPS) and Bureau of Meteorology and Geophysics (BMG). The prediction of the cost that has to be paid by the persons who are exposured by NOx gas and will get respiratory symptomps is done by developing the dynamic simulation model. The result of this research is by 2025 the Jakarta residences that will have respiratory symptomps caused by the NOx air pollution should pay about 1 trillion (1012) rupiahs. To reduce this pollutant it is recommended to develop public policies based on the economic and environmental concern.
