## Abstract
Abstract National sugar production only reached 2.756 million tons in 2014. This number has not been able to meet total consumption of 5.396 million tons. The steam boiler stack generated from coal combustion process in sugar production produces sulfur dioxide gas waste. This research purpose was used as simulation tool to determine the concentration of emissions produced at distance, time, the dispersion of emissions direction, and the type of distribution patterns. The research method was the American Meteorological Society - Environmental Protection Agency Regulations Model (AERMOD). The data input of the AERMOD model consisted of meteorology data, stack emissions, and topography for past 5 years. Meteorological data processed by AERMET was taken from the Hasanuddin station (ID WMO 971800 / WAAA). The topographic data was obtained from the AERMAP model which was downloaded and processed using SRTM3 coordinate data. The result of the AERMOD model was the isopleth map which showed the dispersion pattern of pollutants with different concentrations. The SO 2 concentration value of 6.91348 μg/m 3 was the highest value that occurred at 1 hour measurement since the pollutant was emitted from the stack located 293 meters from the emission source (UTM 774635.04 m and 9435968.83 m).
