Abstract

With the depletion of mineral resources in Indonesia, the need for effective renewable energy alternatives has become critical. Solar energy, harnessed through photovoltaic panels, presents significant potential. However, the widespread adoption of solar panels remains limited due to their large land area requirements and susceptibility to damage. Floating solar panels, installed on water surfaces, offer a promising solution by enhancing energy efficiency through natural cooling while addressing land constraints. This study aims to analyze the motion dynamics of floating solar panels in Semangka Bay and identify the most effective design for open water conditions. Three models were tested: rectangular, kite-shaped, and perforated, using 3D simulation software. The analysis focused on the Response Amplitude Operator (RAO) under regular wave conditions at a 180° angle. The results revealed that Model 3, with 8 mooring points, exhibited the best performance in mitigating rolling, pitching, and heaving motions. The maximum rolling value reached 826.24 cm at 81 seconds, with a minimum of -735.36 cm at 86.7 seconds. Pitching peaked at 390.30 cm at 61.4 seconds and fell to -376.42 cm at 63.9 seconds. Heaving values ranged from a maximum of 17.64 cm at 62.8 seconds to a minimum of -220.94 cm at 83 seconds. This study concludes that Model 3 with 8 moorings offers superior stability, making it the optimal design for floating solar panels in open waters like Semangka Bay. By addressing environmental and implementation challenges, this research contributes significantly to advancing floating solar energy technology in Indonesia. The findings highlight the potential of efficient and resilient designs to harness Indonesia’s abundant solar energy resources effectively.

Abstract

The quality of Marine Fuel Oil (MFO) free from water and impurities is one of the primary factors in maintaining combustion efficiency and the reliability of the main engine's performance on board ships. One of the equipment playing an important role in maintaining this quality is the purifier, particularly through the flushing process utilizing the bowl disc component. However, functional failure of the bowl disc frequently causes a decline in the effectiveness of the flushing process, thereby risking a reduction in fuel quality and disrupting engine performance. This problem is commonly encountered on merchant vessels, including MV. Hammada, where suboptimal purifier maintenance directly affects the smoothness of ship operations. Based on this background, this study aims to analyze the functional failure of the Bowl Disc System on the effectiveness of the flushing purifier action in the MFO fuel cleaning process on board MV. Hammada. This research employs a descriptive qualitative method through direct observation, technical measurements (dial shaft and RPM), and interviews with the Engine Room Chief and Fourth Engineer. The results indicate that stable RPM (7,300–7,425 rpm) and appropriate sealing water pressure significantly influence the success of the separation process. It was also found that variations in purifier operating temperature (76–92°C) affect the resulting fuel quality, with the ideal temperature range being 85–95°C. Factors causing bowl disc functional failure include insufficient routine maintenance, poor fuel quality, and blockage in the sealing water line. Based on these findings, this study recommends increasing the frequency of visual inspections, conducting periodic shaft alignment measurements, and consistently controlling purifier operating parameters to keep the MFO separation process optimal and support the overall reliability of shipboard engine operations.
