Abstract

Sungai Senibung is a body of water receiving waste from industrial activities in the area. Sungai Senibung has a lightly polluted status for the downstream section and a moderately polluted status for the upstream section. Considering the pollution that occurs in Sungai Senibung due to production activities, water quality management is needed. This study aims to determine the pollutant load capacity of Sungai Senibung using the Qual2Kw modeling software. The results show that at pollutant load capacity on point 1, the parameters are TSS 0.0148 kg/day, BOD 0.00007 kg/day, COD 0.0043 kg/day, Ammonia 0.00009471 kg/day, Nitrate 0.00507 kg/day, and Total coliform 2.34 kg/day. Meanwhile, at point 2, the parameters are TSS 0.0047 kg/day, BOD 0.00005 kg/day, COD 0.0006 kg/day, Ammonia 0.00003026 kg/day, Nitrate 0.00165 kg/day, and Total coliform 0.79 kg/day. Overall, the value of pollution load capacity at both points and all parameters is still positive, indicating that the Senibung River is still able to receive pollution loads.
