Abstract

This study aims to analyze the causes of seat ring valve damage and its impact on the performance of the cargo oil pump aboard MT. Transko Antasena, as well as the efforts to overcome the issue. The research was motivated by a discharge delay during unloading of RON 90 cargo at Pare-Pare Port caused by leakage in the seat ring valve of tank 4P/S. A qualitative descriptive method was used, with data collected through observation, interviews, and documentation during the Sea Project period. Data were analyzed using the Fishbone diagram approach. The results show that the damage was caused by improper valve operation, component wear and corrosion, inconsistent SOP implementation, material limitations, environmental factors, and inadequate maintenance. The impacts include backflow, unstable pump pressure, decreased pump efficiency, discharge delays, and potential safety risks. Proposed solutions include improving crew competence, strengthening supervision, conducting routine maintenance, selecting appropriate materials, controlling environmental conditions, and optimizing the Planned Maintenance System (PMS). These efforts are expected to improve discharge efficiency and prevent similar incidents.

Abstract

The captain is the highest leader on board a ship who plays an important role in managing, directing, and supervising all operational activities of the ship. In order for the work process to run optimally, a leadership style that can effectively encourage the performance of the crew is needed. This study aims to analyze the captain's leadership style and how it supports the performance of crew members during the execution of tasks on the MV Kairos Jaya 8 ship. This study used a qualitative descriptive method with data collection techniques in the form of observations made by the researcher during the study, interviews conducted with the captain, chief officer, and crew, as well as supporting documentation obtained during the researcher's PRALA implementation on MV Kairos Jaya 8. Data analysis was carried out using Fish Bone Analysis to identify the root causes The results of research conducted during sea practice (PRALA) show that the captain's leadership style greatly affects the quality of crew work, especially in terms of communication, discipline, and completion of daily tasks. It was found that inconsistency in giving instructions, lack of a persuasive approach, and poor two-way communication can lead to delays in work and decreased crew motivation. Conversely, when the captain applies a more democratic and supportive leadership style, the crew shows a significant improvement in performance, as seen in the accuracy of task execution and increased coordination among crew members
