Abstract

Tofu wastewater contains highly organic compounds such as proteins, fats, and carbohydrates. Without proper treatment, it can cause negative environmental impacts such as groundwater ecosystem disruption, unpleasant odors, and a source of disease. Coagulation-flocculation was one of the methods that could reduce pollutants in wastewater. This study aims to determine the effectiveness of kepok banana peel and moringa seeds as bio-coagulants in tofu wastewater treatment. The research tested various doses of the bio-coagulants from kepok banana peel and moringa seeds, specifically 2, 3, 4, 5, and 6 g/L, with a sedimentation time of 24 hours. Bio-coagulant (moringa seed) usage in a dose of 4 g/L has the highest impact on tofu wastewater. Moringa seeds bio-coagulant increased pH to 4.48, turbidity reduction was 90.67%, COD reduction was 75%, and the TSS reduction was 98.02%.
