PT. Duta Borneo Abadi is a company that produces large-scale concrete as their main product. In the production process, the main machine used is the batching plant machine. Due to its critical role, the batching plant machine has the potential for breakdowns, causing disruptions in the production process. Therefore, the identification and analysis of potential hazards are necessary, using the Hazard and Operability Study (HAZOP) method. HAZOP is a technique for identifying and analyzing deviations in the operation of the machine process. This study used machine damage data, machine maintenance data, pipe and instrument diagrams, and process flow diagrams. Based on the observations, six study points were identified to facilitate the identification of hazards, namely, the aggregate storage zone, weighing zone, delivery zone, cement storage zone, water storage and delivery zone, and mixing zone. The HAZOP worksheet analysis revealed 17 potential hazards, consisting of 15 low-risk hazards and 2 high-risk hazards. Based on the risk potential, recommendations for safeguards for each hazard and the creation of a daily checksheet to check machine components every month are proposed to prevent hazards from occurring.

UD Sekar Jaya is a rice production business that has been operating since 1985 in Bangorejo district, Banyuwangi, East Java. The company sources its raw materials, rice, from various suppliers and also from farmers directly. UD. Sekar Jaya uses rice milling machines, dryers, and kiby machines in its production activities. However, no productivity measurement has been carried out in the production process, and therefore, it is necessary to measure productivity that includes material, labor, and energy. The productivity measurement was only carried out in the production department of premium torch rice. The Multi Factor Productivity Measurement Model (MFPMM) method was used to measure the level of productivity in rice milling or rice production. The results of the MFPMM method showed productivity, price recovery, and profitability from UD Sekar Jaya. After analyzing the results, it was found that the productivity of UD Sekar Jaya has decreased from the material, labor, energy, and total factors. Therefore, productivity improvement implementation was carried out, such as finding good quality rice, increasing tara if the quality of rice is poor, placing workers to examine rice, and implementing a wholesale salary system. Changes in productivity index after the implementation of materials, milling and kiby labor, waste labor, energy, and total input were (1.0087), (1.0828), (1.0828), (1.0352), and (1.099), respectively. This increase indicates that the implementation carried out was successful in improving the productivity of UD Sekar Jaya.

This study focuses on the application of quality control through the FMEA method with the fuzzy approach in the bread food industry. The case study is in PT XYZ, which produces several bread products. The FMEA method is used to identify the potential failure of the production process, but it has a weakness in producing an identical RPN value. To overcome this weakness, the fuzzy approach using the Fuzzy Inference System (FIS) with the Mamdani concept is applied to produce the Fuzzy RPN (FRPN) value. The FRPN calculations can determine the priority improvement in bread products, which can be ranked 1-5. The implementation of the proposed improvements, such as the training of operators, maintenance of machines, repairs of uneven roads, and rest periods for machines, can reduce product disability to 1%. The study shows that the application of the FMEA method with the fuzzy approach is effective in identifying and prioritizing the improvement of product quality in the food industry. The results can help companies to enhance their production process and product quality.

Publisher : Teknik Industri Universitas Ma Chung

PT Inkor Bola Pacific is a company that produces various types of balls according to the demand. However, the lack of a clear list of criteria for selecting suppliers has led to problems in fulfilling raw material needs. This research aims to identify the criteria that must be met to choose suppliers and determine priority criteria. The Fuzzy Analytical Hierarchy Process method is used to determine the weight of each criterion through assessments obtained from questionnaires. The assessment is converted into a Fuzzy scale and the paired matrix is calculated to determine the ranking of each criterion. The results show that the weight of quality is 0.7874 and the weight of price is 0.2126 for fast-moving raw materials. For slow-moving raw materials, quality is given a weight of 1. The prioritization of criteria helps the purchase department to choose suppliers according to the company's standards. The findings can contribute to improving the supply chain management of PT Inkor Bola Pacific and other companies in similar industries.
