Abstract. The concentration of pollutants in the Jragung River differs in the dry season and the rainy season. The purpose of this study was to analyze the effect of the dry season on the water quality of the Jragung River in the Upper Zone. The method used was grab sample with reference to SNI 698957:2008. Meanwhile, water quality data analysis was carried out using quantitative data analysis. Testing was carried out at the Environmental Engineering Laboratory of Trisakti University. The concentration of pollutants in the Jragung River differs in the dry season and the rainy season. The purpose of this study was to analyze the water quality of the Jragung River in the Upper Zone. The method used was grab sample with reference to SNI 698957:2008. Meanwhile, water quality data analysis was carried out using quantitative data analysis. Testing was carried out at the Environmental Engineering Laboratory of Trisakti University. The results showed that the concentration of detergent in the Jragung River at station 1 was 0.07 mg/L and 0.1 mg/L at station 2, both below the quality standard of 0.2 mg/L set by Government Regulation Number 82 of 2001. The Pollution Index (IP) of 7.77 indicates moderate pollution. The pH of the water ranges from 8.4 to 8.7, still suitable for aquatic life. However, several parameters, including COD, DO, Phenol, Phosphate, Oil and Fat, Sulfide, Lead, Total Coliform, and Fecal Coli, exceed the river water quality standard limits so that the use of water from the Jragung River requires a treatment process to meet the class 1 raw water quality standard.
