Optimization on The Hydrolysis Process of Cellulose from Corn Husk to Glucose with Activated Carbon Catalyst Sulfonated

The design of this research consisted of four stages, that is manufacture of catalysts, cellulose hydrolysis process, glucose yield test and optimization process.The research data is plotted in a mathematical model that is optimized using software of Statistica 10 with Response Surface Methodology (RSM) and ANOVA methods. From the RSM method was obtained mathematical equation model for the relationship of the combination of temperature, time and amount of catalyst to glucose levels, that is: Y = -20, 0457 + 5,341x1 -3, 245 + 6, 471x2 -2,798 +4,697x3 -2,965x23 +1,241x1x2 -0,996x1x3 +0,675. ANOVA method produces a value of determination coefficient (R2) as big 0.91545. In this research, the optimum temperature is at 70°C, the optimum time is at 2 hours, and the optimum amount of catalyst is at 11 grams. The results of glucose yield obtained from the optimal operating conditions is 31%.
