Purchasing Consortium (PC) is a strategy in purchasing wich two or more organizations with separate legal entities are merged either individually or through third parties. The main problem that arises in a PC is how to allocate the savings obtained to each member. Generally, the contributions given by each buyer in the purchase differ from one another. Allocation of savings equally to each buyer is no longer representing the contribution of each buyer. The purpose of this study is allocated savings using the Shapley value method of the cooperative game theory. Where each buyer obtained a saving allocation that is in accordance with his contribution. Based on the results of the Shapley value, the results of saving allocations were matched with the contributions of each member who joined the PC. Where buyers 1 with a larger contribution get a greater contribution than the others.

Wet noodles as a source of carbohydrates have a moderate GI value that is 53-56. For this reason, engineering processes was needed to reduce GI value so that it becomes safe and healthy food. Tea (Camellia sinensis) contains tannin polyphenols which can reduce protein and starch digestibility so that the glycemic response decreases. The addition of tea extract to the noodles will result in changes in product properties, so that research on quality of wet noodles with tea extract addition was needed. This research used Factorial Randomized Block Design. The first factor was tea type with two levels and second factor was tea extract concentration with three levels. The parameters observed were organoleptic test, namely taste, aroma and color, and chemical tests, namely protein and tannin content. The research conclusion were: (1) based on organoleptic test, the addition of green tea was preferred over black tea, (2) the addition of green tea and black tea did not caused significant differences in protein content, (3) the tannin content with the addition of green tea tends to be higher than black tea, and (4) the selected treatment was T1K1 (addition of 1% green tea extract) containing 5.81% protein and 15.39% tannin.

Sidoarjo has become one of the districts with the largest number of SMEs and milkfish processing SMEs being one of the superior in Sidoarjo Regency. However, the increasing number of milkfish processing industries even from outside Sidoarjo Regency has caused this industry to be able to compete with various similar businesses from various regions. Therefore, a strategy is needed to improve the competitiveness of processed milkfish. From these problems, the design of increasing the competitiveness of SMEs was carried out with the method of Quality Function Deployment (QFD). The QFD method is used because this method can be used to plan and develop products in a structured manner and allow the development team to clearly define customer needs and expectations, and evaluate the ability of a product or service systematically to meet those needs and expectations. Customer needs and expectations based on the House of Quality matrix consist of 4 indicators including products, prices, packaging, and marketing. While the criteria used were 14 criteria. Development priorities based on House of Quality are marketing, packaging design, quality of additional materials, quality of raw materials, content of additional materials, production equipment, and use of packaging materials.

The population of Sidoarjo Regency with a relatively high number and growth rate has consequences for the increase of waste produced volume. Increasing of volume waste is directly proportional to the increase in population, meaning that amount of waste produced is increasing (organic and inorganic waste). The TPA center in one of the garbage collection locations in Sidoarjo Regency has exceeded capacity (overload). This research was conducted with the aim of describing initial model of the distribution of waste used, evaluating initial performance model of waste distribution in Sidoarjo Regency, and providing recommendations to propose improvements in the waste distribution model used. The method applied in this study was using simulation. Based on the simulation results, the Third Scenario proposed the route with the most efficient distance, this affected the vehicle's operational time and the operational costs needed.
