Abstract

The increasing of fossil energy consumption and will be limited of fossil energy source, cause important to develope alternative energy. One of alternative energy is energy from biomass waste, like agriculture and forestry waste. Those biomass wastes contain cellulose, hemicellulose and lignin. The utilization technology of biomass waste could be done by thermochemical and biochemical process. Direct combustion, gasification, convertion to solid fuel and esterification are the termochemical process, that produce heat supply generator , flameable gas, solid fuel and diesel fuel. Anaerobic digestion and ethanol fermentation are the biochemical convertion, that produce methane gas and ethanol. The energy bioconverrtion technology to convert ethanol from biomass waste are pretreatment, hydrolysis, fermentation, distillation and dehydration.

Abstract

Indonesia as a agriculture country has very much of agriculture and forestry biomass-wastes. Until now, that biomass wastes were sold out without some treatment to produce the higher value product. The agriculture and forestry biomass-wastes contain lignocelluloses material that have 3 groups carbohydrate structure : cellulose, hemicellulose and lignin. That material were potentially to treat to product ethanol that can use as new and renewable energy. It is important, the use of agriculture and forestry biomass-waste did not over-lap with food and feed programe and also support the national energy strategy and green energy concept. Technology convertion of biomass-waste to product bioenergy could be done by physic, chemical and biologically. To enhance the sustainability of the world energy supply, it is necessary to substantially increase the worldwide biomass energy utilization.  The biomass waste is a potentially and interesting as energy raw material. It is one of alternative programe to change non-renewable energy to new and renewable energy.

Abstract

Indonesia have a large amount of biomass wastes, either species or quantitity. If those biomass were not be treatment will be give some negative environmental impacts. To eliminate the negative impact, the biomass waste must be treatment to produce a new product with higher added value. The material utilization of biomass can mainly be categorized into the utilization of the material applying its own property, the utilization of raw material applying its composition and the utilization of it as fertilizer and feed. Convertion into fertilizer, feed, ligneous plastic, biomass mixing, biodegradable plastic are the kind of material utilizations of agriculture and forest waste

Abstract

The quantity, quality and continueity guarantee of raw material supply is a one of define factor for the succesfull of production process. To solve the problems of raw material supply on tapioca industry, it is important to develop a correct raw material supply management. That management must be accurate on quantity, quality, continuity and price. One of the developed management is supply chain managementThe purpose of this paper is to make a cassava raw material supply chain on 100 ton product/day on tapioca industry in an affort to manage a continues and stable of raw material supply. The methods use in this research are to assessment of relatedness between tapioca industry raw material supply chain management with related elements and make conceptual design, pre design and detailed design of tapioca industry raw material supply chain.The result show that depending elements to make a tapioca industry supply chain design system are the information of raw material stock both from cassava farmer or suppliers, the supply information from the patner and buffer stock , the price of raw material, tranportation. Buffer and partnership pattern are two kinds of the best methods to guarantee the fulfill requirement of tapioca industry raw material. Raw material tranportation, storehouse  and refraction are important components on the supply chain management.Based on 100 ton tapioca/day production capacity, convertion of raw material ( cassava) to tapioca product is 5 :1, operation time is 250 days/year, it is need 125.000 ton/year raw material ( cassava ). The requirement suplly of raw material are obtained from cassava farmer 15.000 ton, partner 30.000 ton, buffer 40.000 ton and agent 40.000 ton.
