The Influence of Work Concentration and Crew Rest Hours on Occupational Safety on the MV. Ammar

Abstract

Occupational safety on ships is influenced by various factors, including crew work concentration and rest schedules. High workloads, ship operating rhythms, environmental conditions, and continuous duty duration can reduce crew physical and mental readiness, increasing the risk of accidents. This study aims to analyze the effects of work concentration and rest schedules on work safety aboard the MV Ammar. The method used was a descriptive quantitative approach, with questionnaires administered to all 23 crew members. Data were analyzed using simple regression to examine the relationship between work concentration (X1), rest schedules (X2), and work safety (Y). The results showed that work concentration significantly influenced work safety, contributing 43%, while rest schedules contributed 51%. Simultaneously, both variables had a positive and significant impact, accounting for 67% of work safety. This confirms that the quality of crew work, concentration, and rest schedules must be an important part of ship operational safety management. Recommendations for this study include adjusting work schedules in accordance with the 2006 Maritime Labour Convention (MLC), improving fatigue management, and enhancing discipline and safety awareness.
