Abstract

Background: Situ Pengarengan is polluted by various types of waste from community activities and industrial sources along its shorelines. This study aims to assess the lake's degradation rate by analyzing water quality parameters and pollution sources. Method: The research was conducted from February to July 2022, with water samples collected from six sampling points. Laboratory tests measured temperature, TSS, turbidity, pH, DO, BOD, COD, nitrate, phosphate, and E. coli. The results were compared to Class 2 water quality standards under Government Regulation No. 22 of 2021. Findings: Based on IKA-NSF calculations, Situ Pengarengan's water quality is categorized as moderately polluted, with an average score of 65.04. The degradation rate coefficients for each segment are 2.21 per day, -1.07 per day, and -3.04 per day. Conclusion: The findings indicate moderate pollution levels in Situ Pengarengan, highlighting the need for improved environmental management and pollution control measures. Novelty/Originality of this Study: This study provides a quantitative assessment of Situ Pengarengan’s degradation rate using IKA-NSF calculations and degradation rate coefficients, offering a scientific basis for targeted pollution mitigation strategies.

Abstract

Pangarengan shallow lake in Depok City has been polluted by the garbage that has accumulated in the area and its surroundings as well as the waste water that enters. Pangarengan shallow lake pollution is caused by community activities in the catchment area. The purpose of the study was to determine the water quality of Pangarengan shallow lake. Sources of pullutants that enter the Pangarengan come from surrounding settlements, cattle breeding, and other domestic activities such as stalls and tofu factories. Parameters measured were temperature, TSS, turbidity, pH, DO, BOD, nitrate, phosphate, COD, and E.coli. The air quality analysis will then be compared with the quality standard according to Government Regulation No. 22 of 2021. The status of water quality is determined by the pollution index method. BOD ranged from 4.78-11.90 mg/L, COD ranged from 38.40-86.40 mg/L, phosphate ranged from 0.05-0.29 mg/L, and E. coli ranged from 5,4x103-3,45x104 MPN/100 ml. The Pollutant Index of Pangarengan shallow lake is 5.34. The results of the Situ Pengarengan air quality analysis show that parameters still exceed the quality standards, that are BOD, COD,vphosphate, and E. coli and the water quality status of Pangarengan shallow lake is moderately polluted.
