Abstract

Code is one of the rivers influenced by a large number of waste-generating human activities in Yogyakarta, Indonesia. Despite continued discharges of pollution loads from anthropogenic waste, the heavy metal pollution index (HPI)—a water quality index assessing heavy metal ions present in a body of water—remains nationally underutilized. The research was intended to 1) analyze the river water quality based on metal and nonmetal parameters typical of domestic waste, 2) calculate HPI using either and both parameters, and 3) evaluate the resultant water quality status. The water quality data were the products of temporal river monitoring conducted by the Forestry and Environmental Office for Yogyakarta. The heavy metal parameters included Fe, Cu, Cd, Cr, and Pb, while the nonmetal parameters were BOD, COD, TSS, ammonia, oil and grease, and total coliforms. Each parameter value was compared with the water quality standard issued in Governor Regulation No. 20/2008.  The results showed that the HPI composite of heavy metal parameters classified the river water quality as excellent (2.52), whereas the one representing nonmetal parameters indicated bad quality (55.04). Nevertheless, based on the HPI composed of all parameters, the quality fell into the category excellent (3.94). Consequently, when all metal and nonmetal parameters are combined into the HPI calculation, the river shows a better water quality status.Keywords: HPI (Heavy Metal Pollution Index) water quality, domestic waste, heavy metal, Yogyakarta

Abstract

River water quality in urban areas, particularly in Yogyakarta, has declined due to pollution from domestic, industrial, and agricultural activities. Communal wastewater treatment plants (CWWTPs) were established to address this issue; however, they have not been operating optimally, limiting their impact on improving water quality. Therefore, this study aims to 1) analyze the condition of water quality temporally and spatially in river sections in Yogyakarta City, 2) determine river water quality index temporally and spatially using Canadian Council of Ministers of the Environmental (CCME) method and Biodegradability Index (BI), 3) evaluate the level of water pollution between CCME method and BI, and 4) analyze water quality parameters influencing the pollution level. The study procedures were carried out using the institutional survey method, and data were obtained from temporal water quality monitoring by Yogyakarta City Environmental Service. Water quality assessment was based on standards according to Governor Regulation No. 20 of 2008. Evaluation of pollution levels was carried out using water quality index with CCME method and BI. The influence of dominant parameters was statistically tested using Principal Component Analysis (PCA). The results showed that water quality in Yogyakarta City based on CCME method and BI was dominated by the poor and non-biodegradable categories. Between 2020 and 2023, the CCME and BI index values of rivers showed an increasing trend, indicating a reduction in pollution. The primary factors affecting water quality include NO₂, TDS, temperature, DO, NO₃, and total phosphate, originating from domestic and agricultural activities. In contrast, Cu, Zn, and Cd are primarily sourced from industrial activities.
