Abstract

Utilization of lignocellulosic biomass from sugarcane bagasse for bioethanol production Sugarcane bagasse is one of potential lignocellulosic biomass for energy through physical, chemical or biological conversion. The material is renewable and abundantly available, especially as wastes or by-products of sugarcane industries. Of many conversion processes, lignocellulosic conversion to ethanol becomes focus of interest recently, since ethanol can be further used as biofuel to substitute gasoline for transportation. Lignocellulosic material, including sugarcane bagasse mainly consists of three components, namely cellulose, hemicellulose, and lignin. The conversion of these materials basically consists of pretreatment, cellulose hydrolysis, sugar fermentation to ethanol, and purification of ethanol. Production cost of this conversion is still high; therefore, many researches have been conducted to improve the conversion process, either pretreatment, hydrolysis, fermentation or purification, so that the cost could be reduced. This paper reviewed literatures on potential and characteristics of lignocellulosic materials, especially sugarcane bagasse, and conversion of these materials to ethanol. There is as much as 614,827 kL/year of ethanol potentially produced from sugarcane bagasse resulted from sugarcane factories in Indonesia. This amount of ethanol would have a great contribution to fulfill 1.10 million tons demand of ethanol. However, there are still some recalcitrans in production and implementation of lignocellulosic bioethanol, especially due to the unproven conversion technology of lignocellulosic biomass to ethanol and the high production cost. Therefore, government policies in supporting research and development, providing special incentives for sugarcane factories that produced ethanol from sugarcane bagasse, and giving subsidy to reduce bioethanol price, are needed.Keywords: Sugar by products, lignocellulose, conversion, ethanol

Abstract

Abstract-Sawdust waste in the form of post- production of oyster mushrooms (Pleurotus ostreatus, Jacq. Fr.) presumably still contains a lot of short polymers of lignin derivatives can be chemically modified and becomes activated as a phenol resin adhesive laminated wood , MDF and particle board processing . Phenol resins produced with adhesive properties relative constancy is not much different would reduce dependence on the use of synthetic epoxy resin , while utilizing residual waste is wasted. In lamination technology is determined by factors other than adhesive bonded materials are also factors, gluing techniques, how to test and application materials. Characteristics of phenol resin as the adhesive is often influenced by factors fillers, developer, preservative and fire retardant materials. The use of phenolic resins in the gluing various materials are expected to result in the formation of a resin net structure on a regular basis. Keywords : Waste oyster mushroom (Pleurotus ostreatus , Jacq. Fr.), phenol resins, glue laminated wood
