Cassava skin contains high of starch and is a waste of food industry that is not utilized in Bontang. With obstetrical existence the carbohydrate enable to be exploited permanent upon which produce fuel grade ethanol. The objective if this research was to design of fuel grade ethanol mini plant from cassava skin, to get the comparison between the amounts of raw material of cassava skin with bioethanol product and to know about the characteristics of bioethanol. The processes used to convert waste into bioethanol include hydrolysis, fermentation, distillation, dehydration and condensation. The hydrolysis process use H2SO4 0.3 M as catalyst and give sugar levels of 9.68% and 11.05%. The fermentation process used Saccharomyces cerevisiae for 7 days with 50.46% conversion of sugar to ethanol and for 3 days by 12,38%. The distillation process with sieve tray produces distillate of 435 mL with 70.5% ethanol content. The dehydration process using CaO produces distillate of 288.9 mL with ethanol content of 99.997%. The system has been successfully manufactured and produced with the specification of bioethanol production of 0.1926 liters per 1 kg of cassava waste used.
