Abstract

Durian peel (Durio zibethinus Murr) is one of most agricultural residues that have a percentage of approximately 60-75% and inner durian peel (soft layer) contains 11.78% starch that can be used as raw material for ethanol production. This study aimed to determine the effect of durian peel concentration on bioethanol production and the fermentation time required for bioethanol yield. Bioethanol production was carried out in a batch reactor. Two steps of liquefaction and saccharification were carried out to obtain reducing sugar. In liquefaction, 200 g durian peel flour and α-amylase were mixed with water in an Erlenmeyer 2 litter then was heated at 90°C for 2 hours. In saccharification, this mixture was then heated at 60°C for 4 h. The sugar obtained was then fermented by adding yeast as much as 0.2%; urea 0.5%; KH2PO5 0.5% of the amount of reducing sugar obtained. Bioethanol was obtained by fractionation distillation of the fermentation at 78°C. The results showed that in the saccharification using flour with a concentration of 10, 20, 30, and 40% (w/v) produced reducing sugar of 22.23, 44.25, 55.45, and 84.61 g/l, respectively. Bioethanol in the fermentation process was 1.9, 3.6, 5.2, and 7.3%, respectively. It concluded that maximum bioethanol was obtained approximately 7.3% with the reducing sugar used at 84.615 g/l during 4 d fermentation. The bioethanol content obtained was 95% after fractionation distillation.

Abstract

The location of research is located in the Tanjung Baru Area, Lahat Regency, South Sumatera. The Geological setting of the Tanjung Baru Area in the South Sumatra Basin is included in the Muara Enim Formation the age is Middle Miocene to Late Miocene. Coal in the Tanjung Baru Area, has a calorific value of 5089-5321 Kcal / kg and is rank High in Bituminous Volatile C-High Volatile Bituminous B according to the ASTM classification. Average quality (proximate test) of Muara Enim Formation coal: total sulphur 0.36-1.49% (adb); 1.28-2,5% ash (adb); inherent moisture 9-11% (adb); volatile matter 38.7-42.4% (adb); fixed carbon 45.5-47.9% (adb), total moisture 28.1-28.8% (Ar); relative density 1.28. Coal Charactersitics of Coal Tanjung Baru  the macerals average are vitrinite (92,4% vol.); liptinite (2.9% vol.); inertinite (5,7% vol.). Each macerals or group macerals has different physical and chemical properties. The variation of composition microscopy showed the changes of plant communities or coal facies leading to varies of coal quality, with a average vitrinite reflectance value 0.47-0.58, generally the coal rank is subbituminous-bituminous. Coal gasification is the process of converting coal into synthesis gas. One of the gas produced is a flammable methane gas. Gasification is raw fuel, in this case coal is partially oxidized to produce a product called combustible gas. The main product from the gasification product is synthesis gas or syngas, consisting of Carbon Monoxide (CO), Hydrogen (H2), Methane (CH4), Carbon Dioxide (CO2) and Nitrogen (N2).
