Abstract

Almost all farmers use manual way to identify the level of maturity of oranges in doing the sorting. Identifying using the manual method has some drawbacks, namely the level of accuracy and farmers have already experience. With advances in technology now, sort of citrus fruits is based on the level of maturity can be done using digital image processing. Many digital image processing method one of them is the edge detection method. Edge detection method is used to determine the borders of an object. This study uses edge detection method to determine the extent of the orange color of the peel of citrus fruits because one of the characteristics of citrus fruit maturity level is how dominate the area of orange color on its peel. The results showed that with 10 oranges with a different maturity level, the system can determine it exactly. The average time required by the system to determine the level of maturity of citrus fruits is 0.6 secondsKeywords : citrus maturity, digital image processing, edge detection

Abstract

Flow shop is the process of determining the sequence of jobs that have the same product path. While the flow-shop scheduling takes assumption that a number of jobs that each has the same machine work sequence. The problems faced by com-panies, namely the high demand and yet the existence of a good scheduling planning resulted in the company should be able to optimize sche-duling job. One of the ways to solve these problems is by minimizing the Makespan. This research will solve the problem regarding to the flow shop scheduling by using cross entropy-genetic algorithm (CEGA) method to minimize Makespan. The technique that is used to solve the problem is by comparing the result of the application of existing methods in the company with the proposed method (CEGA). To support the application of CEGA used MATLAB software. Finally known that the results CEGA can give optimal solution, Makespan values obtained for 10829 seconds. So far, it was more effective than the method that used at the firm with Makespan efficiency by 10.06%.Keywords: Flow Shop, Scheduling, Cross Entropy-Genetic Algorithm, Makespan.

Abstract

The fluctuated demand is one of constrain in planning and scheduling process because it affects the cost of production and inventory costs incurred. PT "X" is a sandal maker manufacturing industry that produces sandals and slippers men women. In the manufacture of slippers companies often do not correspond to the amount of consumer demand, so common advantages and disadvantages of production quantities. Master production scheduling (MPS) is a solution to overcome the problem of making sandals to avoid excess and shortage of production of slippers. To create a Master Production Schedule first made a forecast for the next planning period is 5 months of January, February, March, April, May and June.Keyword: Master Production Schedule, linier programming

Abstract

Marine beef is a meat product that has been fat dissolved so that the protein is a major part of the product. Marine beef dry form solid and hydrophilic, has a different performance from the base ingredients, but still contains nutrients according to the characteristics of the original. Weakness marine beef products is shaped in the form of flour so it does not allow for direct consumption. Suweg addition of flour mixture and emulsifier in the manufacturing process can serve as a regulator of the water content, hardness and adhesion to produce a final product that is more compact and high taste. This study aims to determine how optimal levels suweg flour and Na-CMC can be added to marine beef in order to obtain dry products based marine beef with the physical properties, the speed of rehydration and sensory properties that aroma, flavor and texture is good and acceptable to consumers. Treatment of dry meatballs are rich in protein from marine beef with the addition of flour suweg 15% and 1% Na-CMC is the best treatment with the shortest rehidrated pace with time 130 seconds at a temperature of boiling water and the scent of the most preferred by the panelists organoleptic test.Key word: marine beef, protein rich meatballs, suweg, Na-CMC

Abstract

The purpose of this study were (1) Identify the factors that impede business development of micro, small and medium enterprises in East Java, (2) identify strategies flagship relevant for micro, small and medium enterprises in East Java, (3) Develop a strategy formulation the development of micro, small and medium enterprises in East Java as the alleviation of poverty. by using the SWOT method, it can be concluded that (1) the factors that impede business development of micro, small and medium enterprises in East Java is the low marketing,Jurnal Teknik Industri HEURISTIC, vol 12, no 2, Oktober 2015, halaman 142-156 ISSN: 1693-8232143promotion is still lacking, innovation competitor products quickly, the condition of the competitors are very strict, government policy to reduce public subsidies, high inflation, weak niai rupiah against the $ US, demands a quality product at a price that is increasingly Competitive, the decline of the country's economy, political situation in the country is not stable, (2) Strategy flagship relevant to micro, small and medium enterprises in East Java Growth strategy, showed no growth and product diversification efforts, micro, small and medium enterprises, Stability strategy, shows the strategy adopted without changing the strategic direction set. (3) The formulation of the development strategy of micro, small and medium enterprises in East Java as the fight against poverty is (a) Creating opportunities for new markets, for example, Open gallery to accommodate everyone who wants to learn about batik, designs, colors and patterns are new , Producing cotton batik arise, fabric doby, woven fabrics batik, fabric paris (semi ciffon), silk, production of herbal medicine in the form of sachets, Forms/ways of marketing, micro, small and medium enterprises : exhibitions, internet, stand at the site of micro, small, and intermediate, product marketing process: www. petismadura.com through on line, by telephone, came to the site of micro, small and medium enterprises, (b) Measures craftsmen of micro, small and medium enterprises to face competition, for example, cotton batik patterned producing contemporary craftsmen who work in Tanjungbumi invited back to the village in Sampang, designs, colors and patterns are new, it needs creative freedom batik, and according to standard batik, development capital, collecting batik former, For medicinal products: produce products with packaging per ounce, for product paste: improved quality, competitive prices, CSR for young, expanding the image to the public, To handicraft: should innovation models, especially the products of bags and wallets, information from the Internet, (c) Efforts craftsmen that demand the products increases, for example, promotion of one to the other, for batik products: create a new motive, the exhibition, plus employee and machine, plus shops, for the product chips fish : without chemicals, for products skull cap: rent for wholesale, product diversification is koko, exhibits 10 times per year.Keywords: SWOT, micro small and medium enterprise, poverty alleviation
