Abstract

Bioethanol is a bio fuels that can be used for replace fuel oil. It is because bioethanol has many advantages compared to fuel oil. Bioethanol has a good prospect because the main materials that be used for manufacture of bioethanol is very abundant in the environment, which one is pod cocoa. The main method of manufactured bioethanol is hydrolysis which one can transform cellulose to glucose. The product result is used as the base material of bioethanol manufacture. The fixed variable are cocoa skin mass and hydrolysis volume. While the independent variables are hydrolysis temperature, hydrolysis pH, hydrolysis time, and the concentration of H2SO4. Dependent variables is absorbance. The highest glucose concentration obtained was 14.5153 g/L. The maximum temperature of hydrolysis which is used to obtain the highest glucose concentration is 100 ° C. The maximum time of hydrolysis which is used to obtain the highest glucose concentration is 4 hours. Concentration maximum of H₂SO₄ that obtainable to produce the highest concentration of glucose is 1%. The maximum of pH which is used to obtain the highest concentration of glucose is about pH 4-5. The highest concentration of this glucose are fermented to obtain the bioethanol
