Abstract

Cisangkan Sub-watershed is one of the watersheds located in Cimahi City and is part of the Citarum Watershed. In 2018, the water quality of Cisangkan Sub-watershed was in severe condition. The domestic sector is one of the sectors which has the potential to contribute to the pollution of the river. These conditions explain that a study is needed to calculate the pollution load from the domestic sector in Cisangkan Sub-watershed. The purpose of this research was to study the pollution load from the domestic sector of Cisangkan Sub-watershed based on its existing population condition and projection for the next 5 years. The pollution load calculations used domestic waste emission factor, city equivalent ratio, and load transfer coefficient. The results show that the pollution load of the Cisangkan Sub-watershed in existing conditions are 5967.92 kg/day BOD; 8205.89 kg/day COD; 5669.52 kg/day TSS; 290.94 kg/day Total-N; and 31.33 kg/day Total-P and as for the projected conditions are 6149.94 kg/day BOD; 8456.17 kg/day COD; 5842.45 kg/day TSS; 299.81 kg/day Total-N; and 32.29 kg/day Total-P.
