Abstract

PT. XYZ is a medium-sized shipbuilding company engaged in ship repair, maintenance, and new shipbuilding services. The company faces a high potential for workplace accidents in Workshop Area 01, Shelter 05, and the Jetty Area. This study aims to analyze and evaluate workplace hazard potential using the Hazard Identification, Risk Assessment, and Risk Control (HIRARC) method, based on ergonomic principles. The research methodology employed a quantitative and qualitative approach through observation, interviews, and the distribution of questionnaires to 78 workers. The novelty of this study lies in the integration of ergonomic principles into the HIRARC analysis to assess and control workplace accident risks. The analysis results identified 15 categories of potential hazards, with details as follows: 5 low-risk, 8 moderate-risk, and 2 high-risk hazards. High-risk hazards were identified in grinding and plate-cutting activities, which require immediate control measures. Control measures were implemented through the use of personal protective equipment (PPE), technical engineering, administrative measures, and worker education. This study concludes that the integration of ergonomics into HIRARC effectively helps companies identify and reduce workplace accident risks while improving workplace safety and comfort.

Abstract

This paper condenses a Six Sigma DMAIC project implemented in an electric toothbrush assembly line at PT PIB, Batam. Baseline January–September 2025 records 967,700 units with 36,281 defects; leakage contributes ≈60% (21,774 units) and becomes the CTQ. Using Pareto, SIPOC, P-Chart, and fishbone, root causes were traced to unstable air pressure at the leakage tester, rubber-seal mismatch, missing controlled oiling at top-seal assembly, and operator variation. Post-implementation (Oct–Dec 2025) DPMO fell from ≈5,356 ppm (≈4σ) to ≈200 ppm (≈5σ), P-Chart points stayed in-control. These results demonstrate DMAIC effectiveness to reduce leakage defects and stabilize process capability.
