The sustainable and economic development of the fishing industry is heavily dependent upon the choice of raw materials used in fish fodder. Furthermore, an inappropriate amount or nutritional quality of fodder will impede the health and growth of the farmed fish. This work therefore aims to determine the feasibility of substituting snail flour for fishmeal in fodder. The experimental and statistical results indicated no significant nutritional difference between fodder synthesized with fishmeal or snail flour as the protein source. Therefore, snail flour can be used to replace fishmeal used in milkfish fodder without negatively affecting the health of the milkfish.

PT ASIMAS is an enterprise that cultivates and sells oyster mushrooms. One of the most crucial materials in the production of oyster mushrooms is bran. PT ASIMAS is currently facing several difficulties in performance evaluation of bran suppliers, such as no clear standards in the performance evaluation process of suppliers and late shipment of bran. The objectives of this research are to determine the proper criteria and subcriteria and provide improvement recommendation for the enterprise and bran suppliers. This research determines the weights of criteria and subcriteria with the Analytic Network Process (ANP). After that, the performance of bran suppliers is assessed through Scoring System with Objective Matrix (OMAX). The next step is evaluate the performance of suppliers with Traffic Light System. This research eventually resulted in 8 criteria and 14 subcriteria. The results of performance evaluation are as follows: Mr. Hariadi (4.9699), Mr. H. Zainal (4.3622), and Mr. Nur (4.0869). This research result also provides 14 improvement recommendations: 7 for the enterprise and 7 for bran suppliers.

PT SGB is one of the companies that produce Ready To Drink (RTD) beverage as its product and its demand have increased every each year. The company’s supply chain process must be complex, it starts from materials order from supplier, materials storage management in warehouse, producting the beverage itself, finished good storing in the back-off factory then delivering to customers. All those processes belong to company’s supply chain stream and it is mapped as the element of Supply Chain Operation Reference (SCOR). From that complex processes, there were found supply chain risk as the problem. Risks that found in supply chain flow should be solved based on risk priority order. The method that used for analizing the risk is House of Risk (HOR), consist of two phases. The objective of the first phase of HOR is knowing the risk priority that should be mitigated based on the Aggregate Risk Potential (ARP) score, and the objective of the second phase of HOR are generating some preventive strategies and choosing the most effective strategy that suitable to be implemented in the company. Meanwhile, the Pareto chart is used to determine the choosen priority risk to be mitigated. There are 63 identified risk events based on SCOR elements, 43 identified risk agents, and 15 recommended preventive strategies according to the most effective sequence of strategies that applied in the company.

The plastic injection molding process is one of the widely used of the manufacturing process to manufacture the plastic product with high productivity. Moreover, the food packaging manufacturing industry undergoes the trials and errors to obtain the optimal setting of the process parameters in order to minimize the quality issues and these trials and errors are time consuming and costly. The aim of this study is to improve the quality of the butter tub by minimizing the volumetric shrinkage. This study is to deal with the application of Moldflow integrating with the statistical technique to minimize the volumetric shrinkage the butter tub which depends on the process parameters of the plastic injection molding. For this purpose, the rectangular shape of butter tub is designed by utilizing the SolidWorks. Molflow is used to simulate the plastic filling of the single cavity mold of butter tub based on the Taguchi’s orthogonal array table. In addition, the analysis of variance (ANOVA) is applied to investigate significant impact of the process parameters on the quality of the butter tub. Minitab is used to optimize the response of the volumetric shrinkage by selecting the most appropriate process parameters that maximizing the desirability value. Furthermore, the butter tub has a uniform thickness which was 1.2 mm and its factor of safety was 3.383 and the volumetric shrinkage response have optimized by 0.956 %. The melt temperature and mold temperature are found to be the most significant process parameters for the plastic injection molding process of butter tub and the volumetric shrinkage value obtained from the simulation is verified by the calculated volumetric shrinkage value.

Cement Industry for distribute product to consumer has many distributors for each district. One of them an Pasuruan. Pasuruan Distributor has problem that cement’s demands are increasing significantly but sales are decreasing. This phenomenon happened because of the limited capacity of warehouse about 352 m2. Therefore, they planning to additional warehouse capacity with three options (1) Build new warehouse, or renting warehouse from location (2) A or location (3) B. Distributor should conduct a feasibiility study in order to determine the best option. In this research, Analytic Hierarchy Proces) is used to know the interest rate of each criteria. The criteria are location, wide of location and cost. The results shows that AHP value for building warehouse is 0,327. In the other hand, AHP Value for renting warehouse A and B are 0,448 and 0,225. Based on this comparison, rent A will be the best option as it has the highest AHP.

Milkfish is common aquaculture product consumed by Indonesian people. However, the ponds of milkfish in Indonesia manage by Small Medium Enterprises scale of farmers which have problems in sustaining the business. This study proposes supply chain analysis in the upstream level to develop strategic to improve the profit of milkfish farmers. Milkfish supply chain is a network of many actors that work together to create and deliver milkfish and its culinary products to the end-user. This paper defines the partnership strategies between the farmers and suppliers as well as the support from government as facilitator and regulator. Moreover, system dynamic approach analyses the scenarios of partnership to outline the benefit obtain by the milkfish supply chain. Finally, the simulation results recommend the partnership to fertilizer supplier will give significant increase in profit of the milkfish farmers.
