Rivers water resources have characteristics and properties different from other resources, where humans still need water to survive. The rapid growth of the population, especially in urban areas, has a serious impact on the decline in the carrying capacity of the environment. Eco-enzyme produced from simple fermentation of fresh vegetable or fruit waste, brown sugar, and water in a ratio of 1 : 3 : 10 is useful in reducing the level of pollution. Thus, the purpose of this study is to determine the effectiveness of eco-enzyme against the elimination of TSS, TDS, and Surfactant levels in domestic waste. In this study, we used variations in anaerobic processes and coagulation-flocculation with a concentration of eco-enzymes of 7,5% ; 5,0% ; 2,5%. Anaerobic processes take a residence time of 5, 10, 15 days. While the coagulation process – flocculation with 150 rpm on fast stirring for 1 minute, 60 rpm slow stirring for 15 minutes. Eco-fruit enzymes were more effective, the anaerobic process concentration of 5.0% was able to reduce the most optimal pollutant parameters by 8.70% for TSS, 62.42% for TDS, and 7.5% concentration by 98.87% at a stay of 15 days. While the coagulation – flocculation process with a concentration of 2.5% is able to set aside TSS by 7.33%, TDS by 42.07%, and concentration of 7,5% is able to set aside Surfactants by 96.29%.
