Karang Mumus River is one of the tributaries of Mahakam River in Samarinda. The utilization of this river is mostly for domestic activity and other activities by residents near the riverbank. Based on the regulation of local environmental bureau of Samarinda City, this river is not in accordance with the quality standards since some water quality parameters have reached above the threshold. Thus, it can be said that the Karang Mumus river is not suitable for use. This research was conducted using Karang Mumus River water modeling with the Qual2kw program conducted with the aim of being able to simulate both physical and chemical parameters. The data use both primary and secondary data. Primary data was obtained by sampling and measuring several related parameters to be such as BOD, COD, DO, NH4 and TSS. The capacity of Karang Mumus River pollution load for TSS was 218.93 kg/day, BOD was 15.17 kg/day, COD was 127.1 kg/day and NH4 was 2.46 kg/day. Pollution load capacity of the Karang Mumus River has exceeded the value that has been determined. Therefore, it is necessary to reduce the pollution load so that the river can function properly as intended.
