PEMANFAATAN LIMBAH PERTANIAN UNTUK PEMBUATAN BIOETANOL

The Off grade Sugarcane is one of Indonesian native plants that can be used as raw material for bioethanol. Research the manufacture of ethanol made from sugar cane conducted laboratory scale. The purpose of this study was to determine the magnitude of the content of ethanol produced from sugar cane off grade. The procedure of this study consisted of Sugarcane squeeze into juice off grade, heating (formulation) juice, with the addition of yeast fermentation (yeast) and lasted for 6 days with volume Sugarcane juice off grade used is 5 liters. 1 g to yeast, 5 g, with a time of 2 days to 6 days, which is the independent variable in this study. The results showed that the use of a laboratory-scale sugar cane juice off grade of 5 liters weighing 5 g yeast, and time 4 days produces the best ethanol content of 6.30%.
