Abstract

Choosing the right suppliers is important for companies to provide raw materials for production in the long run. The sustainability of production activities is tightly controlled by suppliers in the manufacturing industry. A company in Mojokerto that manufactures PVC pipes falls under the plastic pipe industry sector. Raw materials for PVC resins must be ensured through assessments of suppliers. This study was conducted to determine which resin supplier was the best based on predetermined criteria. Variable include: price, quality, delivery, quantity accuracy, and service. To determine the order of preference for resin suppliers, this study uses AHP, which gives the individual a probability score for each criterion, and TOPSIS, which gives the user an indication of which supplier to choose when selecting a resin. As a result of data processing, suppliers are ranked based on their preferences. The preference values for each supplier are: supplier 1, which is 0.927; supplier 2, which is 0.739; supplier 3, which is 0.091; and supplier 4, which is 0.267. There are five parameters used in this study, and quality is known to have an influence of about 47% on the four suppliers. However, the delivery and service parameters only contribute 5%.

Abstract

As a result of the physical characteristics of metals and their use on a large scale, the industry producing metal products is one of the most important in terms of volume when implementing reverse logistics practices. The relationship between suppliers and customers from the perspective of environmental demands, companies using metal materials are mapped into the Supply Chain operation Reference (SCOR) model. In this study there are Key Performance indicators (KPIs) which are categorized based on the performance attributes of SCOR, namely reliability, responsiveness, agility, cost, and assets management. Using the Analytical Hierarchy Process (AHP) method is an analytical method for the structure of a problem and is used to make decisions on an alternative that is useful for solving complex unstructured problems. The result of this research is that the performance value obtained is a yellow traffic light which means that the application of reverse logistics metal at PT. XYZ has not been implemented properly, so further research must be carried out with primary data in the form of a reverse logistics process each step by step.

Abstract

PT. Petrokimia is seeing escalating difficulties in their supply chain system. Supply Chain Risk Management evaluations can be conducted using many methodologies. Supply Chain Risk Management (SCRM) is a process that involves identifying, evaluating, and reducing risks that have the potential to disrupt the smooth operation of the supply chain, which includes the movement of goods and services. This research combines prior studies by employing a hybrid approach known as House of Risk (HoR) and Interpretive Structural Modeling (ISM). The House of Risk (HoR) method is employed to identify registered risk agents by assessing the importance of preventative measures and selecting priority actions. The ISM methodology is utilized in this study to construct a structural framework for examining the contextual associations among risk elements in the company's supply chain. The organization experienced many hazards, with a total of 20 risk events generated by 30 risk agents across the Plan, Source, Make, Delivery, and Return stages. According to the Pareto diagram concept, there are 11 risk agents that require prioritized mitigation. Out of the 10 risks identified, 1 risk is categorized as dependent while the remaining risks fall within the autonomous sector. Among the 11 primary risk factors, the one with the highest ARP value is anticipated to serve as a benchmark for addressing several hazards that have arisen in the company's supply chain. The research has studied and generated mitigation measures to avoid production losses, time losses, and quality reduction resulting from hazards that may hinder the achievement of company objectives.

Abstract

Nowadays, problems in the industry are increasingly dynamic, including the problem of sustainable supplier selection. Suppliers will significantly affect the stability of the supply chain, especially issues of accuracy, quality, and delivery time. PT Stechoq Robotika Indonesia is an R&D and manufacturing company that produces appropriate technology with bolt components supplied by seven suppliers. Cases of late deliveries that reach four working days have disrupted the smooth running of production, so it is necessary to review current suppliers with objective methods. This study evaluates bolt suppliers by comparing AHP-TOPSIS and FAHP methods according to specified criteria (price, quality, delivery time, accuracy, service). Both ways produce the same highest-value bolt supplier, Supplier #7, and there is a slight difference for the second and third-order suppliers, namely Supplier #1 or Supplier #3. The study results are used as recommendations in determining the main suppliers, supporting suppliers, and replacement or re-evaluation for the three suppliers with the lowest rank (Supplier #6, Supplier #5, and Supplier #4).

Abstract

This research analyzes differences in daily flow and water level using Two-Way ANOVA in the context of ISO 9001:2015. The study was conducted to evaluate significant differences in data during January-March and their impact on continuous improvement. Flow and water level data showed a normal distribution, reflecting stability, but the homogeneity test results revealed significant variations. Tukey's post hoc test showed significant differences between January-February and February-March, but not between January-March. These variations indicate the need to evaluate causal factors, such as weather patterns or operational instability. The research recommends standardizing procedures to maintain consistency of operational processes. Improved monitoring systems are also needed to ensure data reliability. Regular training for staff is an additional solution to reduce variability and support quality. This step is expected to strengthen the implementation of the principles of ISO 9001:2015.
