Abstract

Banana fruit is one of main product of Lampung Province. Banana is commonly utilized as raw material of banana chip production and its peel can be converted into bioethanol. The Objectives of this study were to find out the optimum treatments of  hydrolysis and fermentation for producing bioetanol.  Two steps, namely  hydrolysis and fermentations, were carried out in this study. In the hydrolysis step, two treatments - H2SO4 consentration and hydrolysis duration – were implemented.  The H2SO4 concentration treatment consisted of five level (0, 0.025, 0.050, 0.075, and 0,100 M); and the hydrolysis period treatment consisted of two level (15 dan 30 minutes). Bioethanol fermentation was carried out at room temperature for 72 hours with Saccharomyces cerevisiae as starter at concentration of 0%, 5%, 10%, and 15% (w/v).  The treatments were arranged in Randomized Complete Block Design (RCBD) with three replications.  Before and after hydrolysis, the cellulose, hemicellulose, and lignin contents of  banana peel were determined. The reducing sugar concentrations were measured after hydrolysis, and bioethanol concentrations were measured after fermentation. The  data of the cellulose, hemicellulose, lignin, reduced sugar, and bioethanol were tabulated and analyzed descriptively.  The results of this study showed that the optimum treatment for hydrolysis was H2SO4 solution at a concentration of 0.050 M at 1210C for 15 minutes.  The treatment yielded reduced sugar at a concentration of 11,26mg/100 mL.  The optimum treatment for fermentation was a starter concentration of 10% (w/v) which produced bioethanol at a concentration of 0.03% (v/v). Keywords : banana peel, bioethanol, hydrolysis, H2SO4, reducing sugar.

Abstract

Bintaro fruit is a tropical plant that is widely grown in Indonesia, but it has not been utilized optimally.  Seed of bintaro fruit contains saponin steroids and fatty acids such as palmitat, stearat, oleat, miristat, linolenat, and linoleat fatty acid.  Kernel of bintaro fruit contains saponin and polifenol that are toxic for the pests and insects.  Kernel and seed of bintaro fruit may contain antibacterial activity.  Fatty acid content of bintrao fruit was influenced by level of its maturity, more mature contains more fatty acid.  The purpose of this research is to determine the most suitable solvent to produce the best extract which has activity of anti bacteria and find out the level of anti bacteria activity which is produced from seed and kernel extracts from the bintaro fruit by using difusi agar method.  This research was arranged in a Complete Randomized Block Design, two factorial with four replications.  The first factor was different part of the fruit: seed and kernel.  The second factor was different type of solvent: ethyl acetate, hexane and aquades.  The data were analyzed using Bartlett test for homogeneity and Tuckey test for additivity.  The data then were analyzed using Anova to see the differences between treatments and tested further using LSD of 5% level to determine the best treatment. The result of this research indicated that the kernel of bintaro fruit extracted with ethyl acetate produced the extract which has the highest resistant zone activity of anti bacteria (about 10,95 mm), categorized as an average activity of antibacterial, while bintaro seed extraxted with hexane has less active of antibateria (about 8,43 mm).  The most sensitive bacterium againts seed extracts and kernel of bintaro was Staphylococcus aureus.Keywords : antibacteria, bintaro fruit, extraction, and organic solvents
