    DOI: –

    Abstract

    This study aims to examine the air quality in the Jatiluhur reservoir and observe the surrounding area by analyzing the water and air quality. The study of air quality is used as a reference for policy analysis to measure the air quality that is a source for the surrounding community. The research method used a descriptive analysis using a qualitative approach based on the parameters studied. Some of the parameters studied included the degree of acidity (pH), temperature (oC), Total Dissolved Solid (TDS), and Electrical Conductivity (EC). A total of three water and soil samples from three different locations were taken along the flow of the Jatiluhur reservoir dam. Meanwhile, checks were carried out for air quality measurements at one point by taking data twice. The results show that the air quality is in a safe status starting from TDS, EC, pH, and temperature parameters. While for soil quality, the relative humidity parameter does not enter the normal range because the water content is higher (wetter) even though the content is generally still safe. In conclusion, air quality is still very safe, starting from PM 10, PM 2.5, TVOC, and HCHO levels, all of which are in “Good” status. Based on the measurement of several air, soil, and air quality parameters, it can guarantee that the air quality content in Jatiluhur reservoir is in a safe status for use in daily community activities. © 2022
