Bioethanol is a type of bioenergy that can be used as an alternative fuel. One of the ingredients that can be used is banana stems and jackfruit seeds. Banana stems and jackfruit seeds are materials that contain considerable potential as basic ingredients for bioethanol based on the availability of certain components (starch and cellulose) they contain. The starch and cellulose content found in banana humps and jackfruit seeds can be converted into bioethanol through hydrolysis and fermentation processes. This research aims to synthesize bioethanol from banana humps and jackfruit seeds, determine the effect of the combination of a mixture of banana humps and jackfruit seeds on the concentration of glucose produced from the hydrolysis process and bioethanol produced from the fermentation process. This research began with pretreatment of raw materials (washing, cutting, drying) with variations in the components of banana humps and jackfruit seeds 100% : 0%, 75% : 25%, 50% : 50%, 25% : 75%, 0% : 100 % and variations in starch mass of 1%, 2%, 3%, 4% and 5%. Then the hydrolysis process uses H2SO4 for 1 hour at a temperature of 95˚C-100˚C. Then the hydrolysis results are fermented using Saccharomyces Cerevisiae. The fermentation process lasts for 24 hours, 48 hours, 72 hours, 96 hours and 120 hours. The research results showed that the largest concentration of bioethanol was obtained in the 50%: 50% component with a starch mass of 100 grams of 7% (v/v).
