Abstract
This research utilizes corncob waste as raw material for making ethanol for gasoline fuel mixture. The fuel variations in this study were from a mixture of E5, E10, E15, E20, and E25 with a compression ratio of 10:1, 11:1 and 12:1. The engine speed includes 1400 rpm, 2400 rpm, and 3400 rpm. The results showed an increase in torque from all bioethanol fuel mixtures.
