A coagulant is a chemical needed by water to help settle small particles that cannot settle on their own. Meanwhile, total suspended solids (TSS) result from filter dissolved solids by gravity deposition, usually in chloride particles, and indicate the sedimentation rate. This study aimed to determine the effectiveness of bio coagulants to reduce levels of total suspended solids (TSS) in liquid tofu waste to find out which one is more effective as a bio coagulant in liquid tofu waste. This research is experimental, consisting of 2 stages: the manufacture of charcoal from bio coagulants and the measurement of total suspended solids (TSS) levels. The data collected were tabulated and then analyzed descriptively. Three types of bio coagulants used were tamarind seeds, coffee husks, and cocoa pods. The results showed that there was a decrease in the TSS value before and after coagulation was given. The highest TSS reduction was obtained from bio coagulant charcoal from cocoa pods which reached 54.28% for a coagulant dose of 2 mg/l, while for a coagulant dose of 5 mg/l it could reduce TSS by 70.71%. It means the cocoa pods waste have a potential to use as coagulant to control sedimentation in the environment.
