Abstract

In the era of globalization, the development of the automotive world is increasing in terms of the quality and sophistication of vehicle engines. Meanwhile, the fuel used is running low. Therefore it needs alternative fuel sources such as bioethanol. Bioethanol can be used as a substitute fuel or can be used as a fuel mixture. The purpose of this study is to analyze how much influence bioethanol fuel from plantain tuber waste and pertalite (E0, E10, E20, E30, E40 and E50) has on the performance (torque, effective power, mean effective pressure and fuel consumption) in engines of Honda Vario 2019.This study uses experimental methods with variable fuel-free pertalite and biopertalite. The bound variable is the performance of the motorcycle engine. While the variable control is the Honda Vario 2019 motorcycle in a standard state with a variation in engine rotation of 2000–9000 rpm with a range of 500 rpm and air humidity of 30.6%. This study uses the method of changing speed testing on fully open valves guided by the SAE J1349 standard and for fuel consumption testing guided by SNI 7554:2010. The analytical techniques used for this study are quantitative and qualitative descriptive statistics. Bioethanol characteristics with a content of 99.66% at a fuel calorific value of 7280.50 kcal/l, fuel density of 828.60 kg/m3, fuel viscosity of 1.14 Cps and a flash point of 10.90 0C. The highest test results obtained were on biopertalite E50 fuel with a torque yield of 1.09 kgf.m at 4500 rpm, effective power of 9.37 HP at 7500 rpm, mean effective pressure of 110577.89 kg.m-2 at 5000 rpm and the lowest result of fuel consumption of 0.878 liters/hour at 9000 revolutions on biopertalite E30 but in the average use of motor users on the biopertalite E10 of 0.567 liters/hour at 6000 rpm.
