  • Ethanol or bioethanol is one of the energi resources that can be updated. So it better used as alternative fuel for motor. Developing country like Brazil and America use this etanol and gasoline mixture for motor. The purpose of this research is to get the variation of fuelcomposition (ethanol-pertalite) for performance of sepeda motor matic (matic bike) 125cc. The methode of this research is experimental analysis, doing such tasting directly about the torsion, power, and emission of gas. This research used mixing of pertalite and (25%, 35%, 45%, 55%) ethanol. The result of the research is point to torsion and maximum power that got by mixing 55% etanol. By addding ethanol to pertalite can relieve quality of emission CO, HC, dan CO2, while emission of O2 has not made lowering because over in quality of oxygen in ethanol.
