Abstract

This research aims to design a system for monitoring the performance of ship's Wind Power Plants (PLTB) and IoT-based single-phase electric motor damage detection. The motor monitoring uses real-time current, piezoelectric vibration, and temperature sensors  to detect overload, abnormal vibrations, and temperature rises. The ESP32 microcontroller processes sensor data for display via LCD and IoT. PLTB wind turbines are designed to be adaptive to withstand extreme sea weather to optimize energy. The test evaluates the reliability of the system's response in detecting potential early motor damage through fixed and dynamic measurements. The results show that this system is able to improve the operational efficiency of ships, reduce the risk of sudden damage, optimize renewable energy, and improve overall ship safety through effective periodic monitoring

Abstract

Maritime accidents remain a strategic issue due to operational complexity and human factors. Despite the implementation of the International Safety Management (ISM) Code, effectiveness is impeded by inconsistent procedures, inadequate supervision, and a suboptimal safety culture. The objective of this study is to formulate a national safety policy model for commercial vessels that incorporates multidimensional governance integration to minimize accident risks. A mixed-methods approach with a sequential explanatory design was applied to 186 certified seafarers, including masters, deck officers, chief engineers, and engineers on commercial ships anchored at the port of Tanjung Perak. Start using questionnaire survey of the linkert scale then data were further enriched through interviews, observation. The findings indicate that more than 90 percent of informants stated that there had been an increase in safety awareness on the ship. Nevertheless, elevated work pressures, fatigue risks, and inadequate inter-ministerial coordination were identified. The novelty this research in the development of a comprehensive policy model that integrates a variety of aspects, including regulatory, institutional, human resource, technological, and safety culture, into a unified framework. The efficacy of maritime safety systems hinges on their ability to proactively anticipate risks that transcend the boundaries of formal compliance.

Abstract

This study analyzes the performance reduction of a ship's main propulsion engine caused by cracks in the jacket cooling system. Efficient engine cooling is vital for maritime transport safety and operational efficiency, yet systems often face critical technical failures. Utilizing a qualitative descriptive case study design aboard the bulk carrier MV Sarah S, research data was gathered through observation, semi-structured interviews with engine officers, and logbook documentation. The results reveal an abnormal operating condition in cylinder No. 2, where coolant leakage through material hairline cracks led to a critical drop in jacket cooling pressure (from 3.5–4 bar down to 2–2.5 bar) and a significant surge in exhaust gas temperature to 590°C. Triangulation analysis identified poor cooling water quality (pH below the 8–10 standard) as the dominant root cause accelerating corrosion, material fatigue, and structural cracking. Consequently, heat dissipation failed, disrupting combustion and lowering engine efficiency. This study concludes that temporary corrective measures are insufficient. Sustained propulsion efficiency requires immediate structural repairs combined with rigorous water treatment management and strict adherence to the Planned Maintenance System (PMS).
