: Jackfruit straw is a part of jackfruit that does not experience pollination in the form ofyellow fibers. Jackfruit straw has a composition consisting of 13.45% starch, 65.05% water. Thepotential content of jackfruit straw starch can be used as an alternative fuel, it was, bioethanol. Thismaterial can be converted to bioethanol through hydrolysis and fermentation processes. This studyaimed to determine the effect of variations in the type of solvent and extraction time, used the type ofsolvent H2O, NaOH and NaHCO3 for starch which was then hydrolyzed and produced glucose as a rawmaterial for making bioethanol. The initial content of jackfruit straw was carbohydrate of 11.5%, fat of16.22% and protein of 8.38%. The first step was drying so that the jackfruit straw became powder witha moisture content <14%. Then extraction with a solvent to dissolve compounds that can interfere withthe hydrolysis process such as fats and proteins. This research was conducted by extracting jackfruitstraw powder into starch. Variation of the extraction process was the type of solvent (H2O, NaOH of0.2%, and NaHCO3 of 0.2%) and the extraction time (5, 10, 15, 20, and 25 minutes) at roomtemperature. The results showed that the highest reducing sugar concentration of 2.16% was in the typeof NaOH solvent for 25 minutes.
