Abstract
The construction of PLTU can have an influence on the surrounding environmental conditions, such as air pollution. This study aims to (1) analyze the average air quality in 2013 and 2020 in Bungus Teluk Kabung District, (2) identify changes in air quality conditions in 2013 and 2020 in Bungus Teluk Kabung District. The method used is descriptive analysis with a quantitative approach. The data analysis technique to determine the average air quality uses PM10, SO2, and NOx parameters by utilizing Landsat 8 satellite imagery in 2013 and 2020 which has been radiometrically and atmospherically corrected. The average value of the parameter, can be calculated based on the air quality algorithm, and to measure changes in the state of the air quality standard, the researcher uses the Air Pollution Standard Index (ISPU). The results showed that there was an average increase in all air quality parameters. Based on ISPU the distribution of PM10 values in 2020 is in the good category with an average of 1.9 μg/m3, the SO2 value is in the medium category with an average of 63.3 ρρm, and NOx is in the unhealthy category with an average of 173.6 μg/m3. The results of the Wilcoxon difference test showed that all air quality parameters had a significant value of <0.05, meaning that there was a significant difference in air quality in Bungus Teluk Kabung District after the Teluk Sirih PLTU was built.
