Bioethanol, Tofu Dregs, Cempedak Seeds (Artocarpus champedan), Hydrolysis.



This researchcombinedtofu dregs powderas the nutrition source with enzymatic for cempedak seeds powder (Artocarpus champedan) which was hydrolyzed inethanol fermentation process by using Saccharomyes cerevisiae has been conducted. This research was conducted in order to know the ethanol content that has been produced by doing nutrient concentration variation andfermentation time variation. Hydrolysis processwas conducted enzymaticallythroughliquefaction phase by using α-amylase and gluco-amylasein saccharification phase. Fermentation process was conducted by usingtofu dregsas the nutrition source. Tofu dregs variations used were 1%, 2%, 3% (b/v) and fermentation time variations were (5, 6 and 7) days. The highest ethanol concentration obtained from the addition of tofu dregs nutrition was 3% (b/v) andfermentation time was6days, withethanol concentration obtained was 22,67%.
