【 摘 要 】

Background: The cement industry is one of the main contributors of pollutant gasses in the environment through stack emissions. Aim: This study aims to model the dispersion of SO 2 and NO 2 gasses and to determine the area of the dispersion by American Meteorological Society – Environmental Protection Agency Regulation Model or AERMOD has been utilized by PT. Semen Tonasa (Tonasa Cement, Ltd.). Methods: Meteorological data from AERMENT was collected from reanalysis of MM5 data. While topographical data was extracted from SRTM30 satellite data. The model was carried out for a year, to cover both the dry and rainy season. Results: The result of the modeling showed that the peak value of the concentration of SO 2 and NO 2 pollutants for one hour are 135 μg/m 3 and 160 μg/m 3 respectively (quality standards of SO 2 and NO 2 are 900 μg/Nm 3 and 400 μg/Nm 3 ). The area of dispersion tends to be in the eastern area, such as District Minasatene (Sub-district Bontoa, Kalabbirang, Minasatene dan Biraeng), District Bungoro (Sub-district Biringere, Sapanang, Mangilu, Bulu Tellue) and District Labakkang (Sub-district Taraweang).
