Abstract

This study aims to evaluate the effectiveness of maintenance techniques on 20 kV Power Circuit Breakers (PMTs) using the Research and Development (R&D) method. Key performance variables assessed included contact resistance, PMT synchronism, and insulation resistance. Findings revealed that contact resistance for all phases was below 100 µΩ, indicating optimal connectivity. Synchronism testing showed time differences of 0.7 ms during opening and 1.05 ms during closing, both within acceptable limits. Furthermore, insulation resistance exceeded the 20 MΩ standard, confirming the insulation's integrity. These results suggest that regular maintenance using precise measurement techniques ensures the continued reliability and safety of MV electrical delivery systems. Highlights: Rising Electricity Demand: PT PLN (Persero) faces increasing electricity needs. Advanced Protection Solutions: Innovative equipment addresses conventional limitations.

Abstract

This study introduces a structured multi-criteria decision-making framework using the Analytical Hierarchy Process (AHP), applied to evaluate suppliers based on quality, price, quantity of supply, and plantation area. Effective supplier selection is crucial for maintaining supply chain efficiency. By employing the Expert Choice 11 software, the AHP method quantitatively assessed each criterion, resulting in a definitive ranking of suppliers. The analysis highlighted the paramount importance of quality in supplier selection, assigning it the highest weight (0.565). The outcomes reveal that a meticulous application of AHP significantly enhances decision-making in supplier selection, suggesting its broader applicability in global supply chain management contexts to improve operational efficacy and resilience. Highlights: Structured Evaluation: The AHP method provides a systematic approach to supplier assessment. Emphasis on Quality: Quality is the dominant criterion in supplier selection with the highest weight. Operational Improvement: Implementing AHP enhances supply chain efficiency and decision accuracy.
