ABSTRACT
Bioethanol production from waste cassava peels presents an environmentally sustainable solution to both agricultural waste management and biofuel generation, which is why it is becoming more and more popular as a method of boosting energy security. This research involves several key steps, including cassava peels collection, pretreatment in order to breakdown complex carbohydrates, Acid hydrolysis to convert starch to fermentable sugar, fermentation using Saccharomyces cerevisiae and Aspergillus niger, and distillation to obtain ethanol of high purity. This research focuses on the modelling and enhancement for the production of bioethanol using waste cassava peels. The optimization for the production of bioethanol was conducted by utilizing the Box-Behnken experimental design within the framework of response surface methodology. Three key variables, namely hydrolysis temperature, acid concentration, and fermentation days, were examined as factors influencing bioethanol yield. The optimization of ethanol production was explored under the following conditions: acid concentration ranging from 2% to 6% (v/v), hydrolysis temperature between 110°C and 130°C, and fermentation days of 3 to 5 days. The statistical analysis revealed that the ethanol produced has the highest concentration of 1.901% and was obtained at the optimal conditions of 6.0% (v/v) acid concentration, a hydrolysis temperature of 120°C, and a fermentation duration of 4 day.
