Abstract

The world^s petroleum supplies are dwindling, and the price is rising sharply. Biofuel ethanol (C2H5OH) is a renewable energy that goes through a process of fermentation, distillation, and dehydration. Glutinous rice is the basic material for making bioethanol because it contains carbohydrates that are high enough. The purpose of this study was to determine the characteristics of bioethanol in the form of ethanol content, density, and viscosity. The test results of ethanol characteristics are 98.564% ethanol content, density 0.775 g/mL, viscosity 1.44 cSt. Bioethanol production needs to be further evaluated and improved to meet the important parameters of SNI standards. Further research can be done to improve the characteristics of bioethanol so that it meets SNI test standards.
