Bioethanol can basically be made with basic ingredients in the form of vegetables which contain high starch and carbohydrates such as taro tubers (Colocasia esculenta [L] Schott). The choice of taro in making ethanol is because taro is classified as a tuber like cassava which has 66.8% starch content and 7.2% water content. The process of making glucose is done through acid hydrolysis (HCl) with variations in acid concentration (12, 14, 16, 18, and 20%) and hydrolysis time (1.5; 2; and 2.5 hours). From the analysis, it can be seen that the result of hydrolysis is liquid sugar (glucose) with the highest level of 27.8%brix.
