Abstract

Indonesian archipelagic waters face increasing shipping accidents in narrow channels due to the growth of ship size, logistics intensity, and hydrodynamic challenges such as bank effect and squat, as reported by the KNKT and the case of MV Tonasa Line XI, with previous studies fragmented between human, operational, and environmental factors without integration of optimization for specific routes such as the Amamapare Channel. This study aims to analyze the optimization of ship maneuvering in narrow channels for safety and efficiency and determine the optimal speed to reduce the risk of collision and grounding. Using a descriptive qualitative approach with a case study design on the MV Meratus Dili during the 2024-2025 voyage in Amamapare, a purposive sample included ship officers namely Master, Chief Officer, Second, and Third Officer based on navigational expertise. Instruments included observation, semi-structured interviews, and documentation, analyzed inductively through data reduction, presentation, and drawing conclusions with triangulation. The results show that speeds >6 knots at low tide reduce Under Keel Clearance (UKC) by 0.35 m; radar and echosounder are crucial, but voyage planning lacks tidal analysis. In conclusion, the optimal speed is 4-5 knots during low tide or high traffic, maintaining a UKC of ≥0.5m; improve SOPs through checklists and training to reduce accidents by 20-30%.

Abstract

This study analyzes the use of a manual steering system on the KM. Jetliner in supporting smooth berthing at Kendari Port. The background of this study is based on the importance of the effectiveness of the steering system in ship maneuvers, especially in port conditions with high levels of activity. The purpose of this study is to identify the influence of the manual steering system and the factors that influence the success of berthing. This study uses a descriptive qualitative method with the research subjects of the KM. Jetliner crew who were selected purposively. The research instruments include researchers, observation guidelines, interviews, and documentation. The data analysis technique uses an interactive model in the form of data reduction, data presentation, and conclusion drawing. The results of the study indicate that the manual steering system provides a faster and more precise response than the automatic system at low speed conditions and critical berthing distances. In addition, the success of maneuvers is also influenced by crew coordination, officer experience, and support from bow thrusters and tugboats. The conclusion of this study is that the manual steering system plays a significant role in improving the safety and smoothness of berthing at Kendari Port.
