Abstract

Bioethanol is a renewable fuel that resembles gasoline, bioethanol is produced from fermentation and distillation processes. One of the raw materials that produce bioethanol is Sorghum. Sorghum was chosen as a raw material because it is able to adapt to areas of low soil fertility. This study aims to analyze fermentation longtime and enzyme composition for the best composition to produce bioethanol from sorghum, and determine the quality of sorghum bioethanol. This research Sorghum bioethanol produced with an alcohol content of 94%. The test and analysis variables used were 31 samples. The results of this study are as follows : The best fermentation time is 4 days, the enzyme and yeast variable for the most volume of alcohol is 7% yeast 5% enzyme, the enzyme and yeast variable for the highest alcohol content is 7% yeast 7% enzyme. Laboratory test results when compared with bioethanol sorghum cannot be used as fuel directly as a substitute for gasoline. Sorghum bioethanol can be used as an additive to a mixture of gasoline fuels, if sorghum bioethanol is made addictive with RON 90 gasoline as much as 10% sorghum bioethanol (B10) and 20% sorghum bioethanol (B20) it can improve the performance of gasoline.
