Abstract

Fishing vessels are specialized ships designed to support commercial fishing operations by integrating various structural and functional elements such as hull dimensions, deck layout, load capacity, crew accommodations, propulsion systems, and supporting equipment. One critical yet often overlooked component of such vessels is the lighting system, which plays a key role not only in ensuring operational safety and visibility but also in enhancing fishing effectiveness, particularly during night operations. Currently, many fishing vessels still rely on conventional fluorescent lighting, which is less energy-efficient and has a shorter operational life compared to modern alternatives such as LED technology. This study addresses the inadequacy of current lighting installations on fishing vessels by proposing a redesigned electrical installation system utilizing LED lamps. The objective is to develop an efficient and functionally optimized lighting plan that reduces energy consumption and operational costs while improving onboard visibility. Additionally, LED lights can serve dual purposes on fishing vessels—not only for general illumination but also as fish-attracting lights, which may contribute to increased catch yields. The research employs the Zonal Cavity Method (also known as the Lumen Method) as the primary analytical approach. This method enables the calculation of illumination levels by considering inter-surface reflectance and dividing each interior space into three distinct zones: the High Ceiling Cavity (HCC), High Room Cavity (HRC), and High Floor Cavity (HFC). Illumination levels are then determined according to established lighting standards for each functional area within the vessel. The results of the analysis demonstrate that LED-based lighting systems significantly outperform fluorescent systems in terms of energy efficiency, uniformity of light distribution, and alignment with lighting standards. Furthermore, the proposed installation plan offers long-term operational benefits, including reduced maintenance requirements and lower power consumption. The findings support the broader adoption of LED lighting in small-scale fishing vessels and suggest further research into integrating solar-based energy systems to enhance sustainability and self-sufficiency in future vessel designs.

Abstract

Recent studies have revealed that extreme waves (also known as freak waves), with heights ranging from 20 to 30 meters, occur more frequently than previously assumed. Over the past decades, numerous large commercial vessels have been lost due to incidents involving such anomalous wave phenomena. However, the current design criteria outlined in the 2022 BKI (Biro Klasifikasi Indonesia) Consolidation still consider significant wave heights of less than 11 meters, which is increasingly recognized as inadequate for modern oceanic conditions. This study aims to evaluate and propose ship design parameters that account for extreme wave conditions by incorporating significant wave heights of up to 30 meters into the safety analysis. The methodology involves a comparative analysis between the conventional design standards and a revised model that integrates dynamic wave impact forces as a crucial factor in determining the structural dimensions and stability of ships. The findings indicate that designing ships with consideration of extreme wave scenarios is not only feasible but also necessary to enhance vessel resilience and reduce the risk of capsizing and sinking. This research underscores the urgent need for updating maritime safety regulations and design frameworks in response to evolving oceanographic realities, thereby contributing to the development of safer and more robust marine transportation systems.

Abstract

Carbon Capture and Storage (CCS) is one of the global warming mitigation technology systems by reducing CO2 emissions into the atmosphere. This system is a series of implementations of processes that are related to each other, starting from the separation and capture of CO2 from the source of exhaust emissions (flue gas), transportation of captured CO2 to storage (transportation), and storage to a safe place (storage). If these emissions are released in large quantities, it will certainly cause various problems such as Global Warming. In the maritime transportation sector, one of the emissions that is widely produced by ships is exhaust gas from the ship's main engine when operating which is released into the atmosphere through the Funnel (chimney). One method that can be done is to separate carbon dioxide gas (CO2) contained in the exhaust gas with Membrane Technology placed on the Funnel. Technical analyzes is done by testing the vessel model then the results are developed with naval theories. This article will discuss how to filter carbon dioxide gas and membrane technology that can be used on ships.

Abstract

The depletion of fossil fuel reserves has led to a global energy crisis, with increasing demand for alternative energy sources. Diesel fuel shortages, especially in countries like Indonesia, have driven the exploration of biodiesel as a sustainable alternative. This study aims to convert waste cooking oil (WCO) into biodiesel, with the addition of a cetane number improver (CNI) to enhance its performance in diesel engines. The biodiesel was produced through methanolysis, and 2-Ethylhexyl Nitrate (EHN) was added to improve combustion and reduce engine knocking. The results show that the produced biodiesel had a density of 856 Kg/m³ for B0, 872.7 Kg/m³ for B0 with CNI, and 872.1 Kg/m³ for B50CN. Viscosity values were 2.32 cSt for B0, 5.645 cSt for B50, and 4.722 cSt for B50CN. The cetane index was 49.2 for B50 and B50CN, while B0 had a value of 48. The emissions measured included CO levels of 194 mg/Nm³ for B0, 254 mg/Nm³ for B50, and 280 mg/Nm³ for B50CN. NOx emissions were 852 mg/Nm³ for B0, 755 mg/Nm³ for B50, and 825 mg/Nm³ for B50CN. Oxygen content was 15.9% for B0, 14.9% for B50, and 16.2% for B50CN. The findings indicate that adding EHN to WCO biodiesel improves fuel properties but increases emissions of CO and NOx. Overall, WCO-based biodiesel with EHN is a viable alternative fuel that balances performance improvements with environmental considerations.

Abstract

This research endeavors to explore a novel alternative fuel source by combining waste used cooking oil and corn oil to create a biodiesel blend. The study addresses two main objectives: first, to investigate the properties of used cooking oil biodiesel with the addition of methanol and NaOH catalysts, and second, to assess engine performance using the biodiesel blend. The experimental approach employs transesterification, varying the catalyst quantity during biodiesel production. Preceding diesel engine testing, properties such as viscosity are assessed, revealing improved values meeting Indonesian National Standards post-catalyst addition, albeit with a decrease in calorific value. Engine performance is then evaluated, demonstrating that as the catalyst content increases, torque and thermal efficiency decrease, while specific fuel consumption (SFC) rises. Notably, the study concludes that a higher catalyst ratio aligns fuel properties closer to government-set standards. The most favorable engine performance is observed in the B50 sample with a catalyst variation of 1000 ml of methanol and 25 g of NaOH, showcasing superior torque, thermal efficiency, and opacity values compared to higher catalyst variations. This research underscores the importance of catalyst optimization in achieving an environmentally friendly biodiesel blend with enhanced engine performance.

Abstract

Patrol Ship is a type of ship that prioritizes speed because of its function to secure water areas. This study uses patrol ship design as the object of study in determining the amount of ship resistance because this ship uses an ax bow hull form, the purpose of this research is to determine the effect of the Axe Bow type hull form on ship resistance, freeboard, and ship trim. The method used in this study is a simulation method with the help of maxsurf software. The results of this study indicate that using the Ax Bow Hull Shape model gives a resistance value of 245.9 kN with a speed of 25 knots, a freeboard value of 0.95, and a trim of 0.006575 m and is included in the "Accepted" category. With these results, the use of the axe bow model for patrol ships can be used as an alternative in selecting the hull shape of a fast ship.

Abstract

Diesel engines are widely used in many sectors due to their advantages of high energy density. To reduce emissions in diesel engines, a step that can be taken is to use renewable biofuel such as pure palm oil, which has a high viscosity and is difficult to get a fine atomization process in fuel spraying. However, a detailed analysis of the spray characteristics using pure palm oil fuel on conventional diesel engines has yet to be available. In this research, high-speed imaging was conducted to investigate the spray characteristics of pure palm oil compared to diesel fuel. The result shows that (1) at the start of the injection stage, both pure palm oil and diesel fuel have similar shapes, (2) the spray angle of pure palm oil is smaller due to orifice wall cavitation not occurring in the orifice, (3) and at the end of the injection stage, pure palm oil has larger droplets, which is also more difficult to atomize.
