Abstract

The fuel in Indonesia is decreasing, even in some remote places there was lack of supply, therefore it was the time to find other alternatives such as bioethanol as the waste from cassava skin converted into alternative fermentation through fermentation process and distillation. The objectives of the research were to investigate the effects of distillations process numbers for the fermentation products form cassava skin to the calorie content, engine torque of motor Scopy 2012, and engine power of motor Scopy 2012. Fermentation was carried out for 10 days to get raw fuel so it could be processed into alternative fuel, then be processed with three- level distillation to get bioethanol fuel. This study was a quantitative study, namely experimental testing of alternative fuel resulting from the distillation of fermentation of cassava leather waste. The results of the research with three-level distillation were the first calori was 2837,865 kal/g; the second was 3444,787 kal/g;the third was 3621,911 kal/g; and pertalite is 10571,348 kal/g. For the torque testing, it could be concluded that the average value of the first sample alternative fuel was 10.08 Nm; the second sample was 10.34 Nm; and the third sample was 10.40 Nm. While the average value of the conventional fuel is 10,63 Nm. This showed that the torque on conventional fuel is better compared to alternative bioethanol fuel. The average power produced by the first was 8,1HP; the second was 8,2H; and the third was 8,HP. While the average power generated by the conventional pertalite is 8,2 HP. This showed that the power on alternative was not really different.
