Abstract

Bioethanol is an an alternative fuel that is derived from biomass by Fermentation. Which has advantage of able to reduce co2 emissions up to 18%. In Indonesia, Bioethanol is very potential to developed because the raw material can be update. One of the potential as feedstock ethanol is Tofu waste. Tofu waste represent waste which still contain carbohydrate able to become bioethanol. Bioethanol manufacture of 0,3 M sulfuric acid Hydrolysis during 60 minutes which aims break down starch in to glucose, hydrolysis take place during slurry mixed so the Hydrolysis is complete and in order to navoid lumps. After Hydrolysis followed by Fermentation process using Sacharomyces Cereviceae, anaerobic Fermentation for 8 days. After Fermentation followed by Distillation Process using a Pirolisa Bioethanol, Distilled up to 3 hours/variable, to maximize the ethanol performed Dehydration result with Calcium Oxyde for 1 night. From the Lab work have done, we get the results of ethanol as follows : in the Tank 1A,1B and 1C each Producing Ethanol is 26%, 34%, 47%. While the Tank 2 each respectively 28%, 35%, 48%. Of the Dehydration process is earned the highest ethanol content in the tank 2C.
