The main advantage of biofuel in the form of bioethanol is that it is more environmentally friendly than fossil fuels because bioethanol produces lower carbon emissions when burned. The high cellulose content in cocoa shells has the potential to be further processed into products of economic value, one of which is in the manufacture of bioethanol using a hydrolysis process. The purpose of this study was to determine the effect of variations in sulfuric acid (H2SO4) concentration in the hydrolysis process on the reducing sugar content of cocoa peels as a substrate in the manufacture of bioethanol. The design used in this research is a completely randomized design (CRD) consisting of one factorial, namely variation of H2SO4 concentration (1 M, 2 M, and 3 M (v/v)) in the hydrolysis process. The test of reducing sugar content in this study used the Nelson Somogyi method. The results showed the reducing sugar content of H2SO4 concentration variations of 1 M, 2 M, and 3 M (v/v) were 308 ppm, 200 ppm and 592 ppm. Based on data analysis using ANOVA and Fisher's further test (LSD) at 95% confidence level, the best concentration of sulfuric acid in the cocoa shell hydrolysis process is at a concentration of 3 M with the highest reducing sugar content of 641 ppm at a hydrolysis temperature of 100oC.Downloads
