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. Pineapple (Ananas comosus L. Merr) is a plant that has a native habitat in tropical forests, but these plants can thrive in both lowland and high. Pineapple fruit without knowing the season, so easy to find throughout the year. Ripe pineapple contain a large enough glucose so it can be used as a base for the manufacture bioethanol. Making bioethanol with basic ingridients of this pineapple 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 pineapple with variable addition of yeast 1%, 2%, 3%, 4%and 5% obtained the highest alcohol content of bioethanol with 36% of the fourth variables with the addition 4% of yeast.
