The increase in population causes a decrease in the quality of river water. Rivers are the most vulnerable ecosystem due to human activities. Humans throw the results of daily activities into rivers both from agricultural activities, domestic waste, and industrial activities. This waste results in a decrease in the quality of river water. Therefore the river needs to be managed properly. One of the efforts to manage the river is to determine the absorption capacity of the river itself. However, not many studies have been conducted regarding the absorption capacity of rivers, especially in small rivers. This study aims to determine the absorption capacity of the Palur River using a simple mathematical model called the Mass Balance (Neraca Massa). The results of calculations using the Mass Balance model obtained the average concentration value (Cr) from each segment of the Palur River. The worst river segment is Segment II with an average concentration (Cr) of TSS 54.22 mg/L, BOD 8.12 mg/L, and COD 26.21 mg/L. The calculation results show that the Palur River Segment II no longer has the capacity for TSS, BOD, and COD parameters. Waste that is dumped directly into the river needs to be processed first so that the load entering the river meets quality standards. Furthermore, it is hoped that the results of this study can be used as the first step in efforts to control water river pollution.
