Abstract

Effective communication is essential to prevent collision hazards or other hazards while navigating. VHF Radio is a communication tool that plays an essential role in communicating on board the ship. The Sampit shipping channel uses VHF radio Channel 12 as a pilot channel to assist the communication process when the boat moves in the channel. This study reviews the factors that impact effective communication using VHF Channel 12 radio and the effects caused by communication between ships or shore radio stations not going well. This study aimed to find out how to optimize the use of VHF Channel 12 radio as a pilot channel when the ship is maneuvering in the Sampit channel. The qualitative descriptive method refers to primary and secondary data collected previously, the research method used in this study. The data collected is in the form of articles, journals, news, and regulations related to the use of VHF Channel 12 radio when the ship is operating in the Sampit channel, as well as direct unstructured interviews with the Captain and Ship Officers and Pilots, to find out the factors that impede communication. In the Sampit channel and its impacts. After that, an analysis was conducted to optimize communication in the Sampit channel to assist the ship's maneuvering process. The conclusion obtained is that the provision of strict sanctions for vessels that use VHF Channel 12 as a Pilot channel services for other matters outside their designation is urgently needed to provide a deterrent effect and also training institutions that offer certification of expertise to provide more understanding to training participants regarding the designation function from the VHF Channel 12 as a Pilot Channel.

Abstract

The ballast system is a critical component that ensures a ship's balance on the water.However, if the ballast system does not operate optimally, it can hamper the loading and unloadingprocess and disrupt the stability of the ship. This study aims to identify the factors that lead to sub-optimal ballast water discharge, its impact, and efforts to overcome it. Using a qualitative approach,data were obtained through observation, interviews and documentation, and analysed usingfishbone diagrams and interactive analysis models. The validity of the data was confirmed usingtriangulation method by the first mate responsible for the ballast system. The results showed thatdamage to the ballast pumps, valves and pipes, as well as leaks in the hull were the main causes ofsub-optimal ballast water discharge on the MV. DK 02. This has an impact on hampering theloading and unloading process and disrupting the stability of the ship. Therefore, regular checkson ballast components and adequate availability of spare parts are required to ensure the ballastsystem functions optimally.

Abstract

This study addresses persistent waste-management challenges in coastal urban areas by optimizing the performance of waste-processing equipment at the Reduce-Reuse-Recycle (TPS3R) facility in Pariaman City. It was conducted through a Reliability-Centered Maintenance (RCM)–based repair and preventive maintenance program. The intervention combined field observation, identification of critical components, operator technical training, and the implementation of a structured maintenance schedule adapted to local operational conditions. Implementation involved collaboration among TPS3R management, local community members, and technical staff from Politeknik Pelayaran Sumatera Barat. Data were collected through direct observation, semi-structured interviews, and documentation of maintenance activities. Post-intervention evaluation demonstrated substantive gains in machine processing efficiency, up to an 80% improvement relative to baseline and a marked reduction in breakdown frequency. Operators showed measurable increases in technical competence and consistent adherence to Standard Operating Procedures (SOPs) for safe and effective machine operation. The findings underscore the value of vocational higher-education–community partnerships for technology adaptation, capacity building, and fostering a maintenance culture that supports sustainable urban waste systems. The program represents a scalable, replicable model for similar coastal contexts and contributes to Sustainable Development Goals 11 (Sustainable Cities and Communities) and 12 (Responsible Consumption and Production).
