ABSTRACT
Currently, Indonesian is still relies on non-renewable energy sources (fossil). One
of alternative to replace fossil fuel is with bioenergy such as bioethanol.
Bioethanol can be produced from lignocellulose biomass such as sugarcane
bagasse. Sugarcane bagasse is lignocellulose biomass with 39,26% cellulose,
7,49% hemicellulose, and 23,48% lignin. To take cellulose contained in
sugarcane bagasse, a pretreatment process is needed. Pretreatment process is the
process of removing lignin from cellulose. The purpose of this study is to
determine the optimum conditions of the pretreatment process with time and
temperature variation. The stages that carried out in this study are raw material
preparation, pretreatment, and analysis. Preparation of raw materials is cutting
bagasse up to 0,5 cm and dry it at room temperature. The pretreatment process
used acid solvent with low concentrations of H2SO4 0,5 M with time variations of
30 minutes, 60 minutes, 90 minutes, and temperature variations of 60oC, 80oC,
100oC. Pretreatment analysis was performed using the Chesson-Datta method.
The optimum pretreatment conditions in this study were at time variation of 60
minutes and temperature of 80oC, with 62,84% cellulose and 19,88% residual
lignin. The temperature used in the pretreatment affects the length of time needed
for the process to get optimum results.
Keywords: cellulose, lignin, pretreatment, sugarcane bagasse
