WATER QUALITY ANALYSIS OF SITU CISANTI USING THE POLLUTION INDEX METHOD

Abstract

Situ Cisanti plays a strategic role in maintaining the quantity and quality of water in the Citarum River watershed. Therefore, it is necessary to conduct a study on water quality analysis in Situ Cisanti. The purpose of this study was to determine the water quality status of Situ Cisanti using the Pollution Index method. The tested parameters include total dissolved solid (TDS), total suspended solid (TSS), pH, dissolved oxygen (DO), biochemical oxygen demand (BOD) dan amonia. This research uses a survey method with data collected at three station points, each with four repetitions at 7-day intervals. The sampling was carried out from January to February 2025. Data analysis was conducted using a descriptive-comparative approach based on pollution index calculations in accordance with the Decree of the State Minister for the Environment Number 115 of 2003, following the water quality standards set by Government Regulation Number 22 of 2021. Based on the Pollution Index method, the overall water quality status of Situ Cisanti falls into the lightly polluted category with the pollution index 3,13 – 3,32.
