Abstract
Abstract. The main of tapioca industrial wastes are cassava fiber, cassava skin, and wastewater. To increase the revenue of tapioca industry, cassava fiber was also extracted to produce energy and the effluent of biogas plant was utilized as organic fertilizer. The aims of this research were to estimate energy generation from tapioca wastewater and cassava fiber and also to estimate Nitrogen and Phosphorous potential from the effluent of biogas plant. This research was conducted in a tapioca factory which was equipped with biogas plant, in Lampung Province, Indonesia. Concentration of COD (Chemicals Oxygen Demand), Total Nitrogen (TN) and total Phosphorous (TP) were measured in the inlet and outlet of biogas plant. Enhancement of biogas production from cassava fiber was also estimated. Flow rate of wastewater and cassava fiber production were also measured. Wastewater generation is 2.75 m3/ton of cassava with COD 9,647.5 mg/l. Electricity production was estimated about 29.96 kWh and 30.44 kWh per ton of cassava from the wastewater and cassava fiber, respectively. The observed tapioca factory could be fulfilling energy needs for drying tapioca process if they utilized wastewater and cassava fiber. The effluent of biogas plant also still has potential to produce about 1.15 and 0.05 kg of TN and TP per ton of cassava, respectively.
