<p align="justify">Location of Tarahan Steam Electric Power Plant (SEPP) which is in southern Sumatera makes it possible to be affected by the monsoon wind. In addition, the distribution of SOx waste is affected by monsoon wind as well as atmospheric stability. To see the impact of monsoon wind and atmospheric stability on the spread of pollutants, the distribution of SOx waste produced by Tarahan SEPP was simulated. <br /> <br /> <br /> <br /> Every hour observation data in the months of DJF and JJA were processed and analyzed to find out the wind circulation that affected the wind pattern in the studied area. The simulation was then run to find out the distribution of SOx waste using CALPUFF modeling. CALPUFF modeling is a non steady state puff distribution model that takes into account the impact of variations in meteorological conditions on dispersion, transformation, and disposition of pollutants. <br /> <br /> <br /> <br /> The results of the analysis showed that the wind direction on January 22 was seen to be influenced by the west monsoon wind and on July 10, 2017 was influenced by the east monsoon wind. The distribution of SOx waste during high wind speeds was seen to be more widespread with concentrations reaching Bandar Lampung of 5.5 &#956;g/m3, while at lower wind speeds the SOx was only spread with concentration in the settlements around the SEPP and reached Bandar Lampung at 3.25 &#956;g/m3.<p align="justify">
