【 摘 要 】

Bioethanol (C2H5OH) is a biochemical liquid produced by microorganisms through fermentation process on sugar molecules from carbohydrates. Bioethanol is a fuel of vegetable oil that has similar properties to premium. With its main product of palm juice, Sugar palm (Arenga pinnata) is a potential source of sugar and carbohydrate for bioethanol production. Production of palm juice can reach up to 12-14 liters/tree/day with total sugar content in palm juice ranges from 12-15%. The purpose of this research was to produce highly-concentrated bioethanol from palm juice through fermentation proccess to subtitude fossil fuel. This study was conducted with three stages of treatment, namely: the fermentation of palm juice, distillation of bioethanol, and purification of bioethanol with the addition of adsorbent zeolite and calcium oxide.
