Abstract
Tapioca flour industry produces starchy wastes. Improper handling of this waste can cause environmental problems. The bioconversion of starchy waste to bioethanol has been widely performed. However, the utilization of solid waste from the tapioca flour industry for bioethanol production is still limited. This research is a preliminary investigation to determine the level of ethanol produced from cassava pulp and peel by the fermentation process. Cassava pulp and peel were prepared for the delignification process, hydrolysis process, fermentation process, and finally, the purification process. The fermentation process was carried out by varying fermentation periods, i.e., 2, 4, 6, 8, 10, 12, and 14 days. The highest ethanol concentration at 6.2% was obtained after eight days of fermentation.
