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.

Abstract

Butterworth is one of the main equipment in the tank cleaning process on tankers that plays a role in maintaining tank cleanliness before the next loading. Damage to the Butterworth can cause the tank cleaning process to be suboptimal, thus disrupting the smooth operation of the ship. This study aims to determine efforts to minimize potential damage to the Butterworth and identify obstacles that often occur during the tank cleaning process at MT. Bro Combo. The study used a qualitative method with data collection through observation, interviews, and documentation. The study population included all Butterworth maintenance activities and the tank cleaning process, while the sample was determined purposively, namely officers and crew directly involved in these activities. The research instrument was the researcher with data analysis through data reduction, data presentation, and drawing conclusions. The results showed that efforts to prevent damage were carried out through checking the condition of the equipment, checking the nozzle and connections, proper installation, and routine maintenance after use. Obstacles found included unstable water pressure, nozzle wear, suboptimal Butterworth rotation, and imprecise installation. This study concluded that consistent inspection, regular maintenance, precise installation, and water pressure control are the main factors in minimizing Butterworth damage and optimizing the tank cleaning process.
