Abstract:
Bioethanol gel is an alternative fuel innovation with gel form, that ease packaging and distributing process. Bioethanol gel is modified bioethanol with carbopol as the thickening agent. Based on the result of the study, bioethanol gel as alternative fuel can be produced by hydrolyzing sugar cane waste and fermented with Saccharomyces cerevisiae for 4 days, producing bioethanol gel with 95% grade. Carbopol as thickening agent was added to bioethanol from sugar cane waste, producing bioethanol gel. Best result obtained with the variation of carbopol 1,8 g and NaOH 1 mL resulted to flowing gel. Characteristics of bioethanol gel are: flare time 237 seconds, residue 0,03 g, calorific value 33.064,25 kJ/kg, and 5 g of bioethanol
