| dc.description.abstract | The objective of this research was to study the effect of dairy manure on tapioca wastewater characteristics such as total solid (TS), pH, chemical oxygen demand (COD) and cyanide prepared using anaerobic digester system for 30 days. The waste and dairy manure were combined in the ratios 100%:0%, 90%:10%, 80%:20%, 70%:30% and 60%:40%. The result showed that dairy manure addition in cassava wastewater influenced pH, COD and TS but did not Cyanide. When inoculated with dairy manure, tapioca wastewater obtained indicated increasing on TS and COD. Overall results indicated that the best treatment in this research is combination between waste and dairy manure in the ratio 70% tapioca wastewater and 30% dairy manure to process tapioca wastewater before release at water area.
