Abstract

The problem of limited fuel oil in parts of the world including Indonesia has entered a serious stage because most people still use oil as the main fuel source. Bioethanol is one solution to overcome this problem where this fuel can be made from materials containing sugar, starch or fibre so that it can be renewed. Groundnut shell waste is a very potential raw material because the fibre content is quite high at 54.38%. Waste of groundnut shell is mostly discarded as waste and only a small portion is utilized. The purpose of this study was to determine the effect of Saccharomyces cerevisiae yeast mass and fermentation time of groundnut shell waste on the ethanol content produced. This study used peanut skin with 41% initial cellulose content, 1% initial hemicellulose and 14.3% initial lignin. After pretreatment using 0.5N HNO3 solution at 28⁰C for 1 hour, cellulose levels rose to 55.2%, hemicellulose levels rose to 5.9% and lignin levels fell to 2.1%. Acid hydrolysis process with 10 ml of 98% H2SO4 at 100⁰C for 1 hour obtained glucose levels 23.698%. From the anaerobic fermentation process carried out at pH 4.5, the highest ethanol content was 0.1729% from the results of GC analysis on 9th-day fermentation with Saccharomyces cerevisiae yeast mass of 9 grams.
