Abstract

base mineral oil was one of many product of crude oil fraction which pass through many refining process in refinery. In order to obtain fraction of lubricant oil (base mineral oil) from crude oil need much kind of process to get important traits from lubricant oil. Wherefore the crude oil contain many hydrocarbon compounds and very complex. To get high quality lubricant oil need many processing units and mutually integrated so in the lubricant oil did not contain bad compound later on used in the mechanical engine or vehicle.

Abstract

Banana is one of the fruits that can thrive in Indonesia. This plant is often found in tropical soils with slightly moist soil conditions. However, banana peels are underutilized and are only disposed of as agricultural waste. On the other hand, the carbohydrate content of banana peels is still quite high, reaching 12.2% so it can be used as raw material for making bioethanol. Carbohydrates in the substrate cannot be directly converted into bioethanol but need to be pretreated first to break down polysaccharides into monosaccharides. In this research, the pretreatment process of carbohydrate hydrolysis from banana peels into reducing sugars is studied. From the studies, the reducing sugar concentration was obtained with banana peels substrate concentration of 20 g/L, 5 M of sulfuric acid concentration, and an optimum hydrolysis time of 70 minutes with the obtained reducing sugar reach 16.82 g/L. Reducing sugar can be converted into bioethanol by fermentation process with S. cerevisiae yeast. It is hoped that these studies can provide an initial impact on the development of alternative energy based on biomass and utilization of banana peel waste.
