Abstract

This research is motivated by the rapidly increasing demand for electricity driven by modernization and industrialization, as well as by environmental challenges resulting from reliance on non-renewable fossil energy sources, thereby prompting the search for clean and efficient alternative energy. The aim of this study is to examine the potential and performance of vertical wind turbines as an innovative solution for micro power generation by assessing the efficiency of converting wind energy into electricity and evaluating its economic aspects. An observational research method was employed, incorporating literature review, team discussions, design processes, device construction, and the implementation of testing through both laboratory and field methods. The study was conducted at the Politeknik Pelayaran Sumatera Barat, where the turbine was installed on the roof of a classroom building in a coastal area, taking advantage of favorable geographic conditions and supportive wind characteristics. Data collection involved direct measurements of parameters such as wind speed, turbine and generator RPM, and electrical voltage over designated time intervals, thereby producing data on the variability and operational performance of the turbine. Results indicate that the vertical wind turbine is capable of generating electricity optimally despite fluctuations in wind speed, and it offers advantages in terms of installation flexibility, low operational costs, and energy efficiency with room for improvement. Consequently, the study recommends the development of enhanced aerodynamic designs and more optimal driving mechanisms to accommodate dynamic operational conditions, thereby facilitating the widespread implementation of this solution to support the decentralization of renewable energy systems, reduce reliance on fossil fuels, and strengthen the sustainability of electricity supply.

Abstract

The air compressor is an essential auxiliary machinery onboard MT Seroja III, playing a critical role in supporting vessel maneuverability, operational safety, and main engine starting readiness. During operations, a critical reduction in compressed air production was encountered, leading to prolonged air reservoir filling times and potential risks during ship maneuvering. This study aims to identify the root causes of decreased compressed air production in the main air compressor onboard MT Seroja III and to formulate corrective and preventive maintenance actions based on onboard observations and Fault Tree Analysis (FTA). This research employs a qualitative descriptive method, utilizing continuous monitoring parameter logs, field inspections, and semi-structured interviews with engine officers over a 12-month sea service period. The diagnostic findings using FTA indicate that the decrease in volumetric efficiency was primarily caused by high-resistance suction filter blockages, severe carbon fouling on suction and delivery valves, and piston ring degradation. Corrective maintenance involving filter purging, valve refacing, and piston ring replacement successfully restored the compressor discharge pressure to 30 bar and reduced the air receiver filling time from 45 minutes to 15 minutes. The study concludes that strict adherence to the vessel's Planned Maintenance System (PMS) is mandatory to guarantee operational safety and prevent compression loss.

Abstract

The control air compressor is one of the important auxiliary machines in the compressed air system on board a ship, which functions to supply air for both manual and automatic pneumatic control systems. One of the problems that frequently occurs in this equipment is an increase in internal temperature (high internal temperature) in the Control Air Compressor TMC Type 54-EWNA, which can reduce compressor performance and increase the risk of damage and operational disturbances. This study aims to analyze the causes of high internal temperature in the control air compressor and to determine appropriate corrective and preventive measures. The methods used in this study include direct observation, interviews, and documentation, as well as analysis using the Fishbone analysis method. The results of the analysis indicate that the main causes of increased internal temperature include suboptimal cooling system performance, deterioration of lubrication quality, inconsistent implementation of the Planned Maintenance System (PMS), as well as the influence of environmental conditions and materials experiencing corrosion. The root cause identified is a lack of supervision and irregularity in maintenance implementation. The recommended efforts to address these problems include optimizing the cooling system, using and replacing oil, filters, and coolers according to specifications, carrying out periodic maintenance in accordance with the PMS and manual book, and improving monitoring of compressor operating parameters. By implementing these measures, it is expected that the compressor’s internal temperature can be controlled, compression pressure remains optimal, and the reliability and safety of the ship’s compressed air system can be maintained.
