The development of science and technology in agriculture, has been instrumental in increasing the production of various agricultural commodities. But climate change is also uncertain world led to decreased agricultural productivity. World energy crisis resulted in higher prices of agricultural commodities due to competition between food and energy are higher. Efforts to utilize biomass (agricultural products) has started a lot of research, not only as raw material for bioenergy, but also in an attempt to exploit agro-products into valuable economic products, and realize clean production in agro-industry.

Abstract

ABSTRACTMineral water is drinkable water with a high mineral salt or gas content, either obtained from a mineral spring or with minerals added.  It is usually sold in bottles and satisfy the minimum standard prevailed.  Nowadays, the need for mineral water increase following the increase of population.  Based on the Central Bureau Statistics (BPS) data, the consumption of mineral water in Indonesia was 1.408.148.000 liter in 1994 and it increased up to 3.643.138.000 liter in 2000. Forestalling the enormous need of fresh and dirt-free water, many corporations are growing to provide and produce mineral water.  A corporation marketer needs to understand what the customer needs, perception, preference and behavior in order to satisfy the customer.  Therefore, analyzing the factors of costumer preference toward the mineral water become important to be investigated.  The purpose of this research is to know the customer characteristics and to identify the attributes of mineral water affecting the customer to choose different type of the products.  The other purpose is to compare some of mineral water brands in the market.  The method used to measure the customer preference is Fishbein Multi Attributes Behavior Model.  Finding shows that the most important attributes to develop mineral water is higiene, followed by smell, price, accessibility, taste, advertisment, packaging and brand images. Generally, costumer prefer the mineral water with brand of Aqua than the other brands.Key words : mineral water,  costumer preferences and Multi Attributes Behavior Model

Abstract

ABSTRACTMembrane is a semi-permeable thin layer that can be used to separate components by holding and flowing certain component through pores. The performance of membrane is often evaluated by two parameters, namely flux and rejection. The objective of the paper is to present characteristics of chitosan membrane made using various chitosan solvents and chitosan concentrations. Experimental results showed that rendement of chitosan from shrimp shell was 15.3% with mouisture of 5.5% and ash content of 0.72%. Membrane made using formic acid and chitosan concentration of 7% yielded the highest flux of 285 L/m2h for clean water, flux 52 l/m2h for albumin solution, 144 L/m2h for starch suspension, and 222 l/m2h for glucose solution. The highest rejection was achieved by membrane made from acetic acid with chitosan concentration of only 27 percent for albumine solution. Key words: membrane filtration, chitosan

Abstract

ABSTRACTOyster mushroom can be processed into various cooking and snack, such as crisps, pikel, and crispy.  Oyster mushroom chips are uncommon and brand new secondary product. Nowadays oyster mushroom chips still have not found  in Bogor yet.  The analysis of market and marketing showed that the production of chips in Indonesia was still under the limit of production and appropriate to produce in the future.  It was showed from the utility rate, which was still under 100%.  Cisarua Bogor is the optimum location to develop the chips factory and need 29 employees.  This industry required investment Rp 386.886.813,00 consist of working capital and fix capital.  Pay back period during 1.7 years.  Net present value is Rp 357.960.700,00, internal rate of return is 37 % and net benefit-cost ratio is 1.9.  This means that project is feasible to be applied.  Based on the sensitivity analysis for the decreasing selling price until 15 % and sensitivity analysis for the increasing raw material price until 20 %.

Abstract

ABSTRACTCleaner production is currently considered as a strategic element in manufacturing technology. The application of cleaner production is focused on the reduction or elimination of environmental pollution in their sources, and in the same time in increasing the effectiveness and efficiency of the resource utilization in industrial processes. The objectives of this research were to produce and characterize membranes from natural polymers (cellulose acetate and chitosan), (ii) to test the performance of the produced membrane for cleaner production (wastewater reuse/recycling) in pulp and paper industry as a case study, and ( iii) to evaluate the technical and economical feasibility of the membrane application in the field. Results have shown that a relative high flux of 100 L/m2hr was achieved with the chitosan membrane, which is comparable with the flux of commercial available membranes. The flux of the produced cellulose acetat membrane was relative lower, namely app. 33 L/m2hr.  Turbidity, color and COD (chemical oxygen demand) of the wastewater could be reduced up to 80 - 96 percent, 77 - 99 percent, and 35 - 52 percent respectively, depending on wastewater characteristics, type of the membrane material, and the operating conditions. Based on the measured parameters it is possible to reuse or recycle the treated effluent of the pulp and paper industry by using the membrane filtration. Costs for the membrane material (polymer) were Rp 5.525,-/m2 for the cellulose acetate membrane and Rp 15.000,-/m2 for the chitosan membrane. The material cost for production of microbial cellulose acetate membrane seems to be too expensive, because one kg of dryed microbial cellulose self cost Rp 250.000,-, while commercial cellulose acetat cost only Rp 85.000,-/kg.Key words: cleaner production, membarne filtration, wastewater, pulp and paper industry

Abstract

ABSTRACTEmulsifier in earthworm oil is expected as phospholipid. It is produced from degumming process by the variation of phosphoric acid and citric acid added 0,1% v/w and 0,2% v/w. The highest yield of gum was produced by adding 0,2% v/w of acid. The characteristic of emulsifier such as reducing surface tension, surface tension of two phase, and maintaining the emulsion stability are not different for gum and degummed earthworm oil by acid degumming. Gum by acid degumming is not different from gum water degumming and undegumming earthworm oil in its ability to reduce surface tension and surface tension of two phase. Earthworm oil by acid degumming is not different from earthworm oil by water degumming and undegumming earthworm oil in ability to reduce surface tension and surface tension of two phase. Generally, the ability of undegummed earthworm oil to maintain the emulsion stability is better than gum and degummed earthworm oil by acid and water degumming.
