Abstract
The need of petroleum fuel increases continuously, causing the scarcityoffossilbased fuel. Researches related to renewable energy are intensivety conducted, one of them is bioethanol. One of sources of bioethanol is biomass of lignocellulose, as rain tree pods. The rain tree pods contain about 20% lignin and 42% cellulose. This study focused in the hydrolysis of rain tree pods to yield sugar, which can be fermented into bioethanol. The hydrolysis used the variations of concentration of enzym of celluse ( 0.1, 0.2, and 0.3 gram) with toluent of H2O3 and H3PO4 8%, and hydrolysis time of 24 hours, 48 hours. The highest level of total sugar was 5.58% obtained at 0.3 gram enzym cellulose with solvent of H2O2. For reduction sugar, the highest level was 3.4% obtained 0.3 gram enzym with solvent of H3PO4, and hydrolysis time of 48 hours. The higher concentration of enzym cellulose in hydrolysis process increase the total sugar and reduction sugar content.
