Abstract

The FMCG manufacturing industry faces complex challenges in the supply chain, where supplier performance evaluation is a crucial factor in maintaining production continuity. PT XYZ currently conducts supplier evaluations in a general manner without considering specific segmentation, making it less effective in identifying strategic suppliers and managing risks. The Purchasing portfolio matrix classifies raw materials into strategic, leverage, bottleneck and non-critical groups based on supply risk and profit impact. Meanwhile, the Supplier Potential Matrix (SPM) adds the dimensions of supplier capability and willingness in innovation and collaboration. The combination of these two methods can enhance the effectiveness of supplier evaluation, support procurement strategies, and ensure more optimal business relationships. The weighting of each criterion will be carried out using the Best-Worst Method. Next, the scoring process is conducted based on 13 agreed criteria for each evaluated supplier, totaling 148 suppliers. The results of data processing will be used for segmentation using a hybrid PPM-SPM model. Recommendations are provided for selecting the appropriate supplier relationship management strategy for each supplier segment.

Abstract

In today’s competitive manufacturing industry, maintaining high production efficiency and minimizing machine downtime are critical challenges, particularly in the food sector. This study aims to analyze the effectiveness of ten CBP product packaging machines at PT. XYZ using the Overall Equipment Effectiveness (OEE) method. The research employs a quantitative approach based on primary data collected through direct observation and interviews. The OEE method measures machine performance through three indicators: Availability, Performance, and Quality. The results show that the average OEE value from October to December 2023 is 94%, exceeding the world-class standard of 85%. The dominant loss affecting effectiveness was Equipment Failure Losses (50%), followed by Rework and Defect Losses (22% each). These losses are primarily caused by machine wear, material issues, and operator handling errors. The findings indicate that the OEE method serves as an effective tool for monitoring production efficiency and planning preventive maintenance. Regular operator evaluations and standardized maintenance procedures are recommended to sustain high equipment performance levels.
