Engine Power Optimation with Bioethanol Fuel: An Experimental Study

This study aims to determine engine power after mixing pertalite fuel with bioethanol from cassava. This research is experimental research. The proportion of the fuel ratio consists of a mixture of 10%, 15% and 20%. In this study, the treatment was the use of a variation of pertalite fuel mixture with an ethanol mixture from the fermentation, distillation, and dehydration processes of cassava of the cassava type of manggu on engine performance in the form of power on a 150 CC vehicle.The highest power value obtained from the process of testing the mixture of pertalite and ethanol fuel from the fermentation, distillation, and dehydration processes of mangu cassava to RPM was 11.77 kW in the mixture of pertalite and ethanol fuel from the fermentation, distillation and dehydration of mangu cassava. 20% PE, at 9,000rpm.
