Setu Babakan in the City of Jakarta Selatan contributes economically as a water tourist attraction. With its location in an urban area, growing human activities in its surroundings pose threats of contamination and reduction to its water quality. This research set out to analyze the water quality based on the Class II water quality standard issued in the Governmental Regulation No. 82 of 2001, determine the water quality index, and assess the pollution loading capacity of Setu Babakan. It drew on primary data collected by sampling water at four points in the inlet, middle, and outlet. The parameters observed were temperature, TDS, TSS, pH, nitrate, phosphate, detergent, BOD, and COD, using the CCME method to determine the water quality index and the Regulation of the Minister of Environment No. 28 of 2009 to examine the pollutant loading capacity. The results showed that (1) the pH, TSS, BOD, COD, phosphate, and detergents levels had exceeded the water quality standards, (2) the water quality index of Setu Babakan was categorized as marginal to fair, and (3) this body of water could no longer carry pollutant loads that contributed to TSS, BOD, and COD accumulation.
