## Abstract
The annual increase in waste at the Bantargebang Integrated Waste Management Site (IWMS) is proportionally related to leachate produced. The Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) in the Ciasem River in 2018 exceeded the water quality standards, showing the incapacity to accommodate further pollution. Therefore, this research aimed to assess capacity of the Ciasem River as the receiving water body for Integrated Wastewater Treatment Plant (IWTP) using capacity analysis based on mass balance. The results showed that the temporal water quality has been polluted since 2019 and was projected to continue until 2023, particularly regarding BOD, COD, Total Suspended Solid (TSS), and Total Nitrogen (N-Total). Spatially, high concentrations of BOD, COD, and TSS were observed upstream of the Ciasem River and increased in outfall of IWTP. At the confluence of the Cikeuting River with the Ciasem River, the concentrations of BOD, COD, and TSS showed significant changes due. Although the high concentrations of BOD and COD suggested organic matter decomposition through biological and chemical processes, there was significant no reduction in acidic pH, resulting in low toxicity for Mercury and Cadmium. These results showed that the Ciasem River has lost its capacity, particularly regarding BOD, COD, TSS, and Total Nitrogen, persisting from 2019 until 2023.
