Abstract

Bioethanol from corn husk which contains lignocellulose requires an acid catalyst in hydrolysis process to accelerate the rate of reaction. One of the acid catalysts used is H2SO4 because it is easily obtained and cheaper than enzyme catalysts. The aims of the study are determine the effect of hydrolysis time and H2SO4 concentration toward brix values and bioethanol yield. The method used in this study is a gradual method. With 2 factors, namely concentration (1 M, 1.5 M, 2 M) and hydrolysis time (30 minutes and 45 minutes). The best brix value obtained when H2SO4 catalyst 2 M used. The average bioethanol content produced is 4.99% and the yield bioethanol is 8.58%.
