Natural gas-fired power plants are estimated to generate 24.4% of the electrical energycirculating throughout Indonesia. Several air pollutants that can be generated by the operationof natural gas power plants are sulphur dioxide (SO2), nitrogen dioxide (NO2), andtotal suspended particulate (TSP) with the risk of causing respiratory health complicationsat concentrations that exceed ambient air quality standards. As one of the energy infrastructureslocated in Penjaringan District with a population of 59,142 people, Muara Karang GeneratingUnit (UP) stands out in terms of the impact caused to the environment. This researchusesAERMOD software to model the dispersion of SO2, NO2, and TSP pollutants at the MuaraKarang PLTGU stacks as an ef ort to mitigate pollution and maintain air quality. The operationof AERMOD requires meteorological data managed in AERMET and topographicdataprocessed in AERMAP. Pollutant concentrations in the 1-hour, 24-hour, and 1-year periodswere compared with the quality standards in Government Regulation No. 22 of 2021infivediscrete coordinates and locations that house maximum concentrations of pollutants. Basedonthe results of the isopleth analysis, the maximum 1-hour concentration of NO2 was concludedtoexceed the quality standard, while all subsequent coordinates with measured pollutant concentrations have fulfilled the air quality standards.
