    Alcohol or often called ethanol (ethyl alcohol) in the industrialized world which is often used as a solvent, can be produced by fermentation using the yeast Saccharomyces Cereviceae. The basic ingredients that can be fermented include materials that contain saccharin, starch, and selullosa. Production of ethanol in this study carried out by using the basic ingredients of starch derived from tapioca starch liquid waste that has a starch content of 8.14%. Before the fermentation process, first performed by the process of hydrolysis using bacteria producing enzyme α- amylase is Bacillus to obtain a solution containing sugar (glucose). Result of hydrolysis solution containing glucose at 4.82%, 5.3% and 5.7% then fermented for a certain time interval by using yeast Saccharomyces Cereviceae. From the experimental results obtained a conclusion that maximum results are obtained occurs in 10% bacillus fermentation lasts for 15 days with levels of ethanol produced by 20.14%.
