Abstract

The tofu industry is one of the industries that produce organic waste in solid and liquid waste. The amount of organic liquid waste produced, which is directly disposed of into water bodies without going through good processing, will significantly impact the aquatic environmental ecosystem. The biological treatment of tofu industrial wastewater by utilizing microorganisms on bioremediation process using local microorganisms bio activator of banana weevil is one of the easy, cheap, and fast wastewater treatment. This study aims to evaluate the effect of bio activator volume and the bioremediation process time on Chemical Oxygen Demand (COD) content, Total Suspended Solid (TSS) content, and pH of tofu industrial wastewater in Samarinda City. Firstly, add 30, 60, 90, and 120 ml bio activator volume into 500 ml of tofu industrial wastewater and then bioremedied for two days, four days, and six days. At the end of the process, the remaining COD, TSS, and pH of tofu industrial wastewater were analyzed. The best results of COD content were 6050 mg/L, TSS content was 290 mg/L and pH was 8.16 were obtained at bioremediation process time of 6 days and 120 ml bio activator volume of local microorganisms from banana weevil addition.
