EXTRACTION OF ETHANOL FROM MARANG（Artocarpus odoratissimus) PEELS

The study is focused on the production of ethanol from marang (Artocarpus odoratissimus) peels by hydrolysis, yeast fermentation, and distillation. This study aims to provide an alternative source of fuel biomass out of locally available fruit wastes. The study consisted of three treatments with lengths of fermentation namely three weeks, four weeks, and five weeks. Each treatment has six replications all - three with 20g of sugar and three without sugar. Data on mass and volume, density, specific gravity, percent ethanol, and flammability were collected. Based on the results, the amount of sugar has a significant effect on the production of ethanol from marang peels. It was concluded that fermentation of hydrolyzed marang peels with 20g sugar is more effective than fermentation without sugar. Moreover, the lengths of fermentation showed no significant effect on the percent ethanol and volume of ethanol of the collected distillates. The flammability test also showed that all distillates from solutions with 20g sugar sustained a flame.
