Abstract
Abstract Cikapundung River divides the city of Bandung, one of popular Indonesia’s tourist and educational destinations. The watershed land cover has drastically changed in the last twenty years. This study integrates water quality analysis across the Cikapundung sub-watershed, assessing various physical, chemical, and biological indicators impacted by land use practices. Critical sources of pollution identified include domestic waste, agricultural runoff, industrial discharge, and unpaved riverbanks. Results indicate that numerous parameters exceed Indonesian Government Regulation No. 22/2021 Class II thresholds, notably total dissolved solids, biochemical oxygen demand, chemical oxygen demand, dissolved oxygen, ammonia, Fe, Mn, oil and grease, hydrogen sulfide, MBAS, total coliform, E.coli, and fecal coliforms. The total coliform concentration ranged from 9.25×103 to 5.56×108 MPN/100 mL, fecal coliforms from 7.6×102 to 2.53×107 MPN/100 mL, TSS from 4 to 276 mg/L, and TDS from 88.4 to 1111.15 mg/L. Pollution levels varied across river segments, showing moderate to severe upstream and downstream contamination over three sampling periods. The pollution index ranged from 5.26 to 16.77 across the watershed. This research emphasizes the urgency of implementing pollution control measures and sustainable land use practices to safeguard water quality in the Cikapundung sub-watershed. Its findings provide valuable insights for policymakers and environmental managers to formulate effective watershed management and protection strategies.
