Abstract
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.
Highlights
Water, a crucial part of natural resources to sustain the life of all living organisms, requires carefully planned concerted efforts to preserve and maintain its quality and quantity so that they can make good use of it [1, 2]
Setu Babakan is situated in an urban area, precisely at Serengseng Sawah Subdistrict, Jagakarsa District, the City of Jakarta Selatan
Urban areas are known for their high population density, which may bring about pollution issues [4]
Summary
A crucial part of natural resources to sustain the life of all living organisms, requires carefully planned concerted efforts to preserve and maintain its quality and quantity so that they can make good use of it [1, 2]. Necessary in finding out whether or not a body of water can fulfill human needs, starting from drinking to other varying purposes, such as aquaculture, industry, and animal husbandry. Urban areas are known for their high population density, which may bring about pollution issues [4]. The majority of urban populations have developed a behavior of discarding their refuses directly to the river, and there is a growing number in industrial estates that dispose of improperly treated wastes into the environment, introducing pollutants to waters [5]. Since contaminants can affect the overall quality of waters, human activities are often associated with the reduced usability of several bodies of water [6]. Activities taking place in the surrounding households generate domestic waste that potentially
