Utilization Of Papaya Fruit (Carica papaya L.) As Raw Material Bioethanol With Fermentation And Distilation Process

Abstract

Bioethanol is ethanol that made by biomass containing with sugar components, starch, or cellulose. Bioethanol is usually used to an ingridient for making liquor, for medical purposes, as a solvent, and that are popular today is the use of bioethanol as an altenative fuel. The use of bioethanol as a fuel mixed with gasoline is called gasohol. Papayas (Carica papaya L.) is a plant that has a native habitat in tropical forests, but these plants can thrive in both lowland and high. Papaya fruit without knowing the season, so easy to find throughout the year. Ripe papayas contain a large enough glucose so it can be used as a base for the manufacture bioethanol. Making bioethanol with basic ingridients of this papaya fruit through two stage of the process of fermentation and distillation process. The process of fermentation convert glucose into ethanol with the aid of bacteria contained in cereviceae saccharomyces yeast bread. The process of distillation is purrification process to increase the levels of ethanol producedin fermentation processes. The reactor consists of a series of bioethanol fermentation tanks or tank distilator heating and condenser. For bioethanol the experiment results, it can be concluded that more used amount of yeast more higher level of alcohol obtained. From the results of experiments on the manufacture of bioethanol from banana with variable addition of yeast 1%, 1,5%, 2% obtained the highest alcohol content of bioethanol with 60% of the third variables with the addition 2% of yeast.
