INCREASE PHYSICAL AVAILABILITY OF KOMATSU PC2000-8 USING SWOT ANALYSIS AND FMEA AT MAINTENANCE CONTRACT PROJECT PT ABC SANGKULIRANG EAST KALIMANTAN

Abstract

This study aims to increase the Physical Availability (PA) of the Komatsu PC2000-8 unit at PT ABC’s maintenance contract project in Sangkulirang, East Kalimantan. The PA performance of this heavy equipment has fallen to 89%, below the contractual target of 92%, potentially impacting customer productivity and service continuity. The research adopts a structured DMAIC framework, utilizing SWOT analysis to assess strategic factors (People, Process, Infrastructure) and FMEA to identify technical failure modes. Based on root cause identification, key issues included worn connector sensors, injector malfunctions, and gaps in technician competency and maintenance planning. Improvement strategies were developed using a 5W2H approach and implemented through a revised comprehensive maintenance strategy, as a result, the proposed action plan led to reduced downtime and enhanced PA performance to 94%. Integration of cross-site technician collaboration, data-driven inspections, and a digital KPI dashboard further supported the improvement. This research demonstrates that combining strategic and technical analysis can effectively improve heavy equipment availability in the mining sector.
