UTILIZATION OF SEED CORN WASTE FROM SEED CORN INDUSTRY INTO BIOETHANOL

Abstract

Alcohol or often referred to as 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 among other materials that contain saccharin, starch, and selullosa. Production of bioethanol to the current research done using basic materials derived from waste starch corn kernels from the corn seed breeding industry (PT.BISI INTERNATIONAL Tbk) is 63% starch content. Before the fermentation process, first performed by the process of hydrolysis using the enzyme-producing bacterial α-amylase is Bacillus subtilis to obtain a solution containing sugar (glucose). A solution containing the results of hydrolysis of 15,22% glucose is then fermented for a certain time interval by using yeast species Saccharomyces Cereviceae. From the experimental results obtained a conclusion that the maximum yield is obtained on 6 days hydrolysis bacillus 7,5% and a fermentation process using Saccharomyces cereviceae 7,5% which took place on 9 days with levels of bio-ethanol produced by 6,14%
