Abstract

Supplier performance evaluation is one of the important factors in the supply chain because it is one of the company's strategies for increasing customer satisfaction and also maintaining the company's services in meeting consumer demand. This study proposes the integration of the Analytic Network Process (ANP) and the Preference Ranking Organization Method for Enrichment Evaluation (PROMETHEE) to evaluate supplier performance. The integration of the two methods is proposed to obtain more complex assessment results because the combination of the two methods considers various criteria derived from ANP and various preferences from PROMETHEE, so both methods are very good to use instead of using just ANP or PROMETHEE or other methods. ANP exhibit more complex relationships between criteria and levels in the decision hierarchy, while PROMETHEE provides decision-makers with flexible and straightforward outranking to analyze multi-criteria problems. In this study, ANP is used to weight the criteria, and PROMETHEE is used to rank suppliers in evaluating supplier performance. Integrating these two methods provides more objective and accurate results in multi-criteria decision-making. The proposed method is validated by solving an industrial case of supplier evaluation problem using the real data from the skewer industry. Finally, some useful implications for managerial decision-making are discussed.

Abstract

Intisari— PT Sarwa Jaya Bersama merupakan distributor bihun jagung yang berlokasi di Surabaya. Dalam mendistribusikan produk tersebut, retail memiliki jam buka dan tutup dan kendaraan yang digunakan memilki kapasitas yang berbeda-beda. Permasalahan rute yang dihadapi perusahaan adalah kendaraan kadang-kadang datang terlambat sehingga pengiriman harus dijadwalkan ulang. Selain itu pemilihan kendaraan yang tepat untuk mengunjungi retail akan mempengaruhi total biaya bahan bakar yang dikeluarkan. Untuk menyelesaikan permasalahan perusahaan, penelitian ini mengusulkan penentuan rute dengan menggunakan algoritma sequential insertion. Dengan menggunakan algoritma ini, terbentuk 3 rute dengan jarak tempuh yang lebih minimum dan kedatangan kendaraan berada pada jam buka dan tutup pada masing-masing retail. Penghematan biaya bahan bakar dengan rute usulan sebesar 45,31% atau sejumlah Rp 254.720. Abstract— PT Sarwa Jaya Bersama is a distributor of corn vermicelli located in Surabaya. In distributing these products, retailers have opening and closing hours and the vehicles used have different capacities. The route problem faced by the company is that vehicles sometimes arrive late so deliveries must be rescheduled. In addition, the selection of the right vehicle to visit the retail will affect the total fuel costs incurred. To solve the company's problems, this research proposes determining the route by using sequential insertion algorithm. By using this algorithm, 3 routes are formed with a minimum mileage and vehicle arrivals are at the opening and closing hours of each retail. The fuel cost savings with the proposed route is 45.31% or Rp 254,720.

Abstract

A micro-hydropower plant is a small-scale power plant that uses water as its propulsion and the prime mover is a turbine. This generating system is very appropriate to be used in rural areas because this system is easy to manufacture, produces a large amount of electrical power, and is relatively inexpensive to manufacture. Based on the above, it is necessary to design a turbine that supports this generating system, including the Cross-Flow Turbine. To design a water turbine so that there are no errors in the design (such as the cost of making it), then a design is carried out. A cross-flow turbine design is designed with a flow rate (Q) = 1.2 m3/s, head (H) = 17 m with an efficiency of 0.75. The main technical specifications from the results of the turbine design are runner diameter (D) = 510 mm, turbine shaft rotation 471 rpm with a specific speed of 61.33 rpm, water power of 200,124 kW, and producing electric power of 100.86kW.

Abstract

Indonesia is currently entering a new normal era; this requires people to adapt to the clean-living habit in accordance with health standards in order to carry out normal activities. At the same time, online transportation services have reopened for activity. The service quality provided by online ride-hailing companies (i.e., ojek) such as Gojek, Grab, and Maxim must now consider matters relating to user safety. This study proposes Multi Criteria Decision Making (MCDM) as a method for assessing the service quality of online transportation service providers and uses the Pandemic-SERVQUAL 4.0 model. Pandemi-SERVQUAL 4.0 model adds two new criteria, namely "pandemic" and "industry 4.0". The addition of two new criteria that are more relevant to the current circumstances will increase the accuracy of the research. This study aims to propose the integration of Interval Valued Intuitionistic Fuzzy Analytical Hierarchy Process (IVIF-AHP) to determine the criteria weight and Interval Valued Intuitionistic Fuzzy Weighted Aggregated Sum-Product Assessment (IVIF-WASPAS) to assess the service quality of several online transportation service providers based on the obtained criteria weights. From the results of the service quality assessment using the integration of IVIF-AHP and IVIF-WASPAS, the ranking of online transportation service providers during the new normal era were Grab-car, Go-car, and Maxim-car.

Abstract

Along with the increasingly tight competition, companies are required to always be consistent in improving the quality of its products. Improvement of product quality can be achieved through minimization or even reduction of product defects. This study aims to minimize defects by providing improvement suggestions based on critical failure modes The Six Sigma approach is adopted to reduce the occurrence of product defects. The FMEA-FSWARA-FWASPAS FMEA method is integrated in the six sigma approach, especially to determine the priority of failure modes and the recommended efforts to minimize failure modes that trigger product defects. FSWARA is used to determine severity, occurrence, and detection weights as failure mode assessment criteria. Meanwhile, determination of the critical failure mode is based on the results of the evaluation using FWASPAS. This research is based on a case study in which 5 types of defects were found, namely, skewness, underfilling, leaks, broken lids, and broken boxes. The main causes lie in the human factor and the machine factor. The results showed that there were 3 critical failure modes, namely, the wrong setting of the cutter timer by the operator, the frequent change in the heater temperature, and material getting damaged

Abstract

This article investigates the integrated approach of the Simultaneous Impor­tance-Performance Analysis (SIPA) model and the modified Kano model to evaluate and prioritize service attributes for telecommunication companies in Indonesia. The study is based on the demographic profiles and usage patterns of 74 respondents. The results demonstrate that the SIPA and Kano models can provide valuable insights for identifying priority areas and effective strategies for improving service quality. Specifically, the SIPA model helps to compare competitor performance and identify important service attributes. In contrast, the modified Kano model facilitates a dynamic cycle of service attribute evaluation to inform managerial strate­gies. This article contributes by highlighting the potential of the proposed ap­proach to offer valuable insights to telecommunication companies seeking to enhance their service offerings and remain competitive in a con­stantly evolving market.

Abstract

This study proposes an economic production quantity (EPQ) model that comprehensively addresses scrap items, imperfect quality items, rework processes, and shortages. The model incorporates various types of defective items, including scrap, imperfect quality, and rework able items, and implements immediate rework processes upon the completion of regular production. Shortages are treated as lost sales, enhancing the accuracy of inventory cost estimations. Numerical experiments demonstrate the opti­mal­ity of production lot sizes and underscore the impact of production and demand rate adjustments on overall inventory costs. Sensitivity analysis further elucidates the influence of imperfect quality items on inventory costs. This EPQ model offers a comprehensive approach to efficient and effective finished product inventory management by integrating consider­ations for scrap items, imperfect quality items, and rework processes. Addi­tionally, a furniture manufacturing company case is presented to illustrate the practical application of the proposed model.
