- Cassava peel is a solid waste that contains 59.31% carbon which has the potential to serve as active carbon absorbent and useful for absorbent material, especially organic substances, colors and odor. Based on this, the authors conducted a study that aims to determine the effectiveness of activated carbon cassava peel in reducing levels of BOD and TSS tapioca starch factory waste water. The study was Quasi experiment using Pre and Post Test Plan with the addition of activated carbon treatment of cassava peel as much as 1 g, 2 g, 3 g and the control (0 g) in each 200 ml of water in which each treatment was done 3 times repetition. The results showed that at concentrations of 0 g, levels of BOD and TSS (1013.2 m /l, 1722 mg l), at a concentration of 1 g (150 mg/ l, 56.4 mg /l), at a concentration of 2 g ( 197.2 mg/l, 63.4 mg/l), the concentration of 3 g (429.8 mg/l, 69.6 m /l). Based on the One Way Anova test shows that there are significant differences between treatment with various concentrations of active carbon cassava peel in reducing levels of BOD and TSS starch factory wastewater Conclusion of the study is from Duncan's test results and test Honestly Significant Difference (BNJ) showed that the concentration of active carbon cassava peel an optimum (best) to reduce levels of BOD and TSS concentrations of tapioca wastewater is 1 gram of being able to reduce levels of BOD and TSS in accordance with requirement effluent quality standards based on KepMenLH No.51 of 1995. In connection with these studies, the author suggests to the manager of starch plant for tapioca processing wastewater using activated carbon made from cassava peel. In addition, further research is necessary to know the effect of adding activated carbon to the levels of cyanide cassava peel waste.
