Abstract
The bagasse residue of Sweet sorghum (Sorghum bicolor (L.) Moench) consist of cellulose 39.48%; hemicellulose 16.56% and lignin 24.77% that can be converted to ethanol. Pretreatment is of great importance to ethanol yield. In this study, pretreatment process was conducted in a 5-liter reactor using NaOH 10% at various temperature 110, 130, 150oC and reaction time 10, 20, 30 minutes and optimizing severity parameter (log R0 between 1.3 - 2.9). The statistical analysis using two way anova showed that third variations of temperature give different effects significant on lignin, hemicellulose and cellulose content at 95% the confidence level. The optimum pretreatment of bagasse sorghum were obtained with Log R0 value between 2.4-2.9. High severity value in pretreatment condition reduce lignin almost 84-86%, maximum reducing lignin content was 86% obtained at temperature 150oC for 20 minutes reaction time and cellulose increased almost two times the initial content.
