Magetan distric t at East Java is one of local government that support their farmer to participate in forward auction market in order to expand its marketing network . Th e implementation of the commodity auction market is divided into three main processes , i.e. pre - a uction, auction , and post- auction . Problem mapping was done by spreading questionnaires on 37 respondents, interviews in related government officer, and benchmarking on commodity auction organizers . There are many problems faced by farmer and forward auction market o r ganizer. Government that have the role of facilitator and catalyst need to carry out such some improvement activities to increase the efficiency of the commodity distribution. However , the local government need a tool to determine fundal location for facilitating farmer and action organizer . In this study, we solve d theproblem with approaches: the initialidentification , mappingproblems ; the hypothesis of suggestion of improvement ; model development ; and finally makes verification and validation using expert justification . This article aimed to formulate alternative solutions to overcome problems in the implementation of the auction market and formulate a model of government fund allocation . Goal programming was developed to s olve problems with mu l ti objective functions. The model use d four performance criteria , i.e. risk level, incentive value given by government , benefit value, andfarmer level skill . The results show ed that the model was able to provide optimal fund allocation by minimizing t he level of risk and incentive value and maximizing the va l ue of the benefits and skills o f farmers .

The packaging design elements that have appeal and take into account consumers' Kansei are crucial in introducing new products and influencing purchasing decisions. Integration of packaging design elements to produce a certain character has a combination and complexity, but can produce unequal perception. To reduce the emergence of perceptual ambiguity, then in the design process requires a measurable and standard model. The purpose of research were to design the attributes and sub elements and to make the decision rules so that the knowledge obtained underlying consumer expression. This research used a combination of Business Process Model Notation method to explain activity and data flow, Relief and Principle Component Analysis method to select design attributes and packaging selection, and Bayes Rough Set method to get the combination of decision rule. The results obtained represented the design elements and packaging samples such as size, colour, letter writing, and packaging bottle grouping as a means of reducing the number of samples. The Kansei expression of seriously was explained by a combination of text writing products that were not legibility, small font size, single color on the text, the dominant color of brown labels, black, green and no illustration of the image. The Kansei expression of eye cathing was explained by the combination of the design attributes of the sharpness of the colour, the text of the product, the text size of the product, the product text colour and the dominant colour, and the water illustration. The ergonomic aspect of bottled beverage design was that if it has a combination of high-element proportional bottles, it has a curved, low bottle cap, and a small bottle bottom diameter.

Synthesis of diethanolamide (DEA) surfactant from palm olein methyl esters has the potential to commercialization. This surfactant product can reduce surface water tension from 72 dyne/cm to 33.82-32.06 dyne/cm in laboratory scale and the synthesis process was 50% cheaper than palm kernel fatty acids. So that, it is necessary to review the surfactant DEA production from palm olein methyl esters. The purpose of this research was to get the best synthesis process of DEA surfactant on 25 L/batch reactor. The synthesis process of DEA surfactants was divided into two stages. The first stage was conducted to determine duration and stirring rate of the DEA surfactant synthesis process. Then the best result in this first stage was continued in the second stage of the synthesis. The second stage was conducted by using an installed bulkhead in the reactor and some agitators for the DEA surfactant synthesis process. The lowest value of surface tension was the main parameter that was used for determining the best synthesis of DEA surfactant. Based on the first stage results, it was known that the best synthesis process was 4 hours with 100 rpm stirring rate. In the second stage, it was concluded that the best type of agitator was propeller. The best surface tension of DEA surfactant resulting from this research was 14.28 dyne / cm. The other parameters produced from the synthesis process were yield of 95.24%, viscosity of 245.41 cP, density of 0.973 g/mL, and pH of 11.1.

Palm oil industrial cluster development in Sei Mangkei is a step to realize the downstream programme, increase the added value and competitiveness through integrated management. To optimize the development, it is necessary to make the planning starting from the selection of potential industries, as well as calculate how optimal capacity, with the availability of raw materials as constraints. The selection of products is done with the exponential comparison method with the result that industrial cooking oil, margarine, basic oleo chemicals, surfactants, biodiesel, industrial soap, liquid soap, shampoo and detergents, as well as biogas and animal feed were potential for development in the industrial park. The goal programming analysis was performed to determine the optimal industrial capacity that provide maximum benefit and labo u r, and minimal waste produces. Based on the optimization analysis, the profits target was achieved and the largest profits derived from basic oleochemical industry, margarine, cooking oil, and soap bars. While labo u r targets were not achieved, because labo u r absorption less than 80% of the target. The target of waste was achieved, and the largest proportion of liquid waste was produced by cooking oil and basic oleochemicals industry. This model is expected to illustrate the capacity calculation model of industry in other cluster development. Keywords: goal programming, industrial park, optimization, palm oil industrial cluster,

Synthesis of foaming agent was conducted by reacting fatty acid of vegetable oil and alkaline. In this study, the selected fatty acid consisted of palm oil as raw material; with NaOH and KOH as alkali materials. The factor observed was molar ratio of reactant added into reactor. This research was aimed to determine the best molar ratio to produce foaming agent from lauric acid, to know its physico-chemical propertie,; and to obtain the foaming agent performance. Statistical analysis result indicated that the alkali type and molar ratio exhibited significant influence on pH, viscosity, density, surface tension, contact angle, interfacial tension, foam stability, and emulsion stability. The best ratio was by 1 mol of lauric acid and 0.5 mol of KOH 30% w/w with characteristics as followed test was performed at room temperature for 24 h, pH of 9.88, density of 0.9959 g/cm 3 , viscosity of 1.85 cP, surface tension of 3.14 dyne/cm, interfacial tension of 8.39 dyne/cm, and contact angle of 18.28 o in the 10 th minute (with initial angle of 73.99 o ).

This paper proposed a queue model for beverage order picking system produced from agricultural commodity in warehouse with drive-in rack system in order to analyze and increase the warehouse performance. A (M/M/C):(GD/N/∞) queue approach was used to build the model with the queue approach. This paper considered total operator must-be-assigned to improve queue time (Wq), queue length, and utilization in the warehouse. Stack, queue, linked list, Colour HSB (Hue, Saturation, Brightness) algorithms were used to represent drive-in rack, product queuing, and product status in the warehouses. The model was implemented in computer simulation using java programming. After build the model, a real case industrial problem was presented to test the model. The model could calculate warehouse performance including low performance in racking, transportation to loading area, and loading process for current number of operators and idle operator in the warehouse process. This result was in line with the industry condition that has over capacity and high product bottlenecks in the warehouse. The model was used to find and analyze total operator-must-assigned to increase the warehouse performance. The computer simulation showed colour changing based on density of product stack in queue area. This colour degradation helped for easier understanding and accelerating product status detection (including hold, ready-to-release, and expired beverage products in the warehouse).

Separator attched to MFC system can reduce the distance between cathode and anode and limit oxygen penetration to anode chamber. The use of Chitosan/polyvinyl alcohol (PVA) mixture polymer as membrane separator was expected to have ability to increase electron recovery from the substrate. The objectives of this research were to increase the standard quality of wastewater of salted boiled fish processing and to increase bioelectricity generation, through the membrane separator adding to MFC system. Separator polymer was made by blending 2% chitosan and 5% PVA solution, in different ratio of chitosan (K) and PVA (P) at 2:3 (K 2 P 3 ), 1:1 (K 1 P 1 ), 3:2 (K 3 P 2 ), and without separator. The study was carried out to measure electricity generated and to analyse of BOD, COD and TAN of the wastewater. The K 2 P 3 treatment showed the highest electricity generation with average voltage of 0.50±0.06 V, maximum current density 0,29 mA/cm 2 , and maximum power density 15.40 mW/cm 2 . The reduction of COD showed insignificantly different among treatments, but the reduction of BOD and TAN values showed significantly different. The BOD value reduced to56.54% in K 2 P 3 treatment and the TAN value reduced to 92.73% in K 1 P 1 treatment. Keywords : chitosan, microbial fuel cell, polyvinil alcohol, separator

Halal certification is a form of moslem consumer protection to solve halal problems. Acceleration of the submission process depends on accuration and completeness of the proposed requirements document. This research objective was to accelerate the registration process of halal certification, especially on data entry phase of materials which applied into decision support system. Decision support system can be used to determining the supporting documents of materials types. Input to the decision support system were names of materials from the products to be certified. The decision support output came from integration of decision tree analysis with J48 model and critical points of materials which resulted 43 rules. The output from this system consisted of flow process diagram, technical specifications, COA (Certificate of Analysis) or material purchase documents, halal certificate, and blank document. The decision support system had been developed into web-based system using hypertext preprocessor (PHP) programming language and MySQL (My Structured Query Language) database management system. Keywords : decision support system , decision tree halal certification, supporting document of materials, web base

Neem cake oil has an active compound in form 242.2 ppm azadirachtin. The active compound has activity as feeding inhibitor, nesting rejection, growing inhibitor and mortality effects of many insect pests. Therefore, neem cake was extracted to produce oil. The purpose of this research was to obtain the best ratio of extraction oil from neem cake by maceration method and oil neem cake formulated by DEA surfactant. The oil extraction from neem cake was undertaken by maceration method using a solvent like n-hexane and produce the greatest yield at comparison neem cake and n-hexane 1:4 (w/v). The oil was produced from extraction of neem cake was solid form at room temperature, so it was added a general solvent as usually used in the pesticide industry to dissolved. i.e. Solvesso. The concentration of DEA surfactant used in neem cake oil formulation was 8%. The bioinsecticide formulations of this research was 8% DEA, 15% for oil neem cake and 15% for Solvesso in 30 g formulations . Keywords: DEA surfactant, insecticide formulation, maseration method, neem seed oil
