Bioethanol is ethanol produced from glucose fermentation followed by the distillation process. The purpose of this study was to examine the performance of gasoline-fueled motors using bioethanol fuel mixed with pertamax (RON 90) and pertalite (RON92) fuels with a mixed percentage of B0%, B5%, B10%, B15%, and B20%. In this research, bioethanol is made from basic ingredients of coconut roomie ( Cocos nucifera ), which is fermented then continued with the distillation process to obtain bioethanol with a purity level of 80%. Bioetahnol is used as a fuel mixture using a gasoline fuel motor. The results of testing the mixture of bioethanol B20% and pertamax (RON 90) fuel with the highest torque is 11.94 Nm at rotation 2600 rpm. Bioethanol B20% and pertalite (RON 92) fuel with the highest torque is 11.79 Nm at rotation 2600 rpm. Bioethanol B20% and pertamax (RON 90) fuel the highest initial power is 4.58 hp at rotation 2900 rpm. Bioethanol B20% and pertalite (RON 92) fuel’s the highest power is 4.52 hp at rotation 2900 rpm. Bioethanol B20% and Pertamax (RON 90) fuel shows that the lowest specific fuel consumption is 0.28 kg/hp.h. Bioethanol B20% and pertalite (RON 92) fuel the lowest specific fuel consumption pertalite is 0.29 kg/hp.h. The greater the percentage of in pertamax (RON 90) fuel and pertalite (RON 92) fuel, the specific fuel consumption will be more efficient. In the mixture of pertamax (RON 90) fuel and bioethanol B20% is the largest value torque and power, but specific fuel consumption is the lowest.
