Abstract

The Bali Strait is a busy shipping lane with heavy traffic, where external factors such as strong winds and currents often hinder the maneuverability of Ro-Ro vessels like the KMP Trisakti Adinda, interacting with internal factors such as hull fouling. This study aims to identify the internal and external factors hindering maneuverability as well as mitigation efforts. Using a descriptive qualitative approach, the population consisted of the entire crew (22–28 people) on the Ketapang–Gilimanuk route, with a purposive sample of five key informants (Captain, First Mate, Engineer). Instruments included semi-structured interviews, observation, and documentation; analysis followed the Miles–Huberman method (reduction, display, verification). Results indicated that wind (20–30 knots), drift currents, low visibility (<0.5 miles), flat-bottomed hulls vulnerable to side forces, and fouling increased resistance by 5–10%. Conclusion: Effective mitigation through adherence to COLREGs, radar use, routine fouling maintenance, and enhanced safety measures

Abstract

As a busy shipping route, Indonesia experiences a high number of maritime accidents caused by human factors such as miscommunication and fatigue; therefore, the implementation of Bridge Resource Management (BRM) needs to be evaluated to ensure maritime safety. This study aims to analyze the effectiveness of BRM through responsibility, crew skills, and performance improvement efforts on the bridge of the MV ABM Nubiri. Using a descriptive qualitative approach, the population consisted of the entire bridge crew (17 people), with a purposive sample of three key informants (Captain, Chief Officer, and Helmsman). Research instruments included semi-structured interviews, participant observation, and documentation; analysis was conducted using the Miles-Huberman interactive method with triangulation. Results indicated clear task division, effective communication through repeated commands, and good situational awareness; however, these were hindered by fatigue and low participation from junior crew members. Conclusion: BRM is effective but requires routine training and fatigue management to optimize safety.
