Judul: Potensi Pajanan Sulfur Dioksida (SO2) pada Masyarakat di Sekitar Wilayah Industri di Musim Kemarau.
Abstrak: As an industrial area, Tangerang district has high upper respiratory tract infection (URI or URTI) and tuberculosis cases. Sulfur dioxide (SO2) is one of industrial waste gases causing those diseases, the concentration tends to increase along dry season. By employing a model, a research related to the air pollutant exposure and public health can be more practical and efficient. This study aims to analyze the exposure of SO2 to the residents around Tangerang district in dry season including distribution of SO2 concentration emitted using Chimere model, the mass of pollutants inhaled by individual, Inhalation Transfer Factor (ITF), and Population Inhalation Transfer Factor (PITF). Results of Chimere model showed that SO2 concentration along dry season reached 0.2-2.7 μg m-3 and the mass of pollutants inhaled by individual ranging from 0.16–21 μg hr-1. ITF and PITF estimations for PT X in unstable atmospheric condition (A) were 2.7x10-8 and 9x10-5 respectively, whereas 1.2x10-9 and 4x10-5 in stable atmospheric condition (F) respectively. ITF and PITF estimations for PT Y in unstable atmospheric condition (A) were 4x10-8 and 1.3x10-4, whereas in stable atmospheric condition (F) were 1.9x10-8 and 6.5x10-4 respectively. Those PITF values were categorized as urban ambient air ranging from ~10-6- ~10-3.

Judul: Model Prediksi Distribusi Laju Penyebaran Sulfur Dioksida (SO2)dan Debu dari Kawasan Industri (Studi Kasus di Kota Cilegon)
Abstrak: This study aims to examine the characteristics of local air; analyze the concentration of air pollution emitted from factories located in an industrial area; and predict air pollution distribution the city of Cilegon. Several sequential steps of analysis are carried out which include: (1) calculation of high-layer pollutant mixing in the atmosphere (mixing height), (2) analysis of emission of air pollutant from the source point using screen3 model; (3) analysis of distribution of air pollutant from the industrial area using general transport equation of unsteady flow. Based on climatology, Pasquill stability criterian indicate that stability profile in the region ranges from A (very unstable) to E (slightly stable). Pollutant distribution from the industry depends on the height of the chimney. The higher the chimney is, the further the distribution of the pollutant as a result of emission is expected to be. The highest concentration of SO2 is found in the emission of industry area, with atmosfheric stability class A (very unstable), whereas furthest distance occurred stability E class (slightly stable). The distribution of SO2 extends towards Tamansari village of Pulomerak District. From 24 sampling points, the highest concentration of 55,75 ìg/m3 occurred in the ASDP Merak. The levels and patterns of air pollutant distribution in the area need to be taken into account, particularly in the interest of protecting public healthlife from the impacts caused by the pollutant.
