Abstract

This research investigates the incorporation of LED lights and the zonal cavity method in the initial design stage of a cargo-type ship, focusing on efficient lighting for diverse ship zones. The study aims to determine optimal lighting requirements, adhering to industry standards, for zones such as double bottom, maindeck, poopdeck, boatdeck, bridgedeck, navdeck, and emergency conditions. Ships play a vital role in transporting passengers and goods across seas and rivers, necessitating effective lighting systems for safe operations, particularly during nighttime. This paper explores the integration of LED lights and the zonal cavity method in the general arrangement design of a cargo ship. The zonal cavity method is applied to ascertain lighting intensity in different ship zones based on room dimensions, including width, height, length, and area. Illumination values are determined according to established standards for each zone. The cumulative lighting electricity load for various ship zones using LED lights is calculated to identify specific power requirements.The lighting power requirements for the double bottom, maindeck, poopdeck, boatdeck, bridgedeck, navdeck, and emergency conditions are found to be 0.141 KW, 0.75 KW, 1.068 KW, 0.762 KW, 0.671 KW, 0.42 KW, and 0.296 KW, respectively. The total lighting power for all zones is calculated as 3.7776 KW, suggesting the installation of a 4 KW generator for optimal power supply.The application of the zonal cavity method in the planning and design of a cargo ship's lighting system, combined with energy-efficient LED lights, proves to be an effective approach. The results indicate that a 4 KW generator is sufficient to meet the lighting power demands for various ship zones, ensuring compliance with safety standards and technological advancements in maritime lighting.

Abstract

Many types of bananas are grown in Indonesia, indicating that it is one of the banana producing countries. Banana leaves are processed to make them stronger and more easily absorbed, so they are suitable as a composite mixture. Making banana stems as an alternative reinforcement for composite materials. Use ecologically safe substances and replace synthetic compounds. The aim of this research is to investigate the tensile strength and flexural strength of banana stem material as a composite fiber alloy in ship component materials in accordance with the review of the Indonesian Classification Bureau (BKI). The method used is experimental testing with a UTM machine according to ASTM D638-03 standards and ASTM D-790 standards. The results of the test experiments show that the tensile strength and flexural strength of banana stems as a composite and natural material are not yet suitable for use as boat component materials under water (hull skin construction), according to BKI's review, but can be used as an alternative composite material for boat component materials above the water line.

Abstract

The 26.80 meter long tugboat plays a critical role in Indonesia’s maritime operations, particularly in towing and maneuvering vessels between Semayang Port and open sea areas. As part of its operational infrastructure, the vessel relies on fluorescent lighting systems, which are known to be less energy efficient and less durable than modern lighting technologies. This presents a significant operational challenge, particularly in light of rising fuel costs and the global shift toward more sustainable maritime practices. This study addresses the issue of inefficient energy use in onboard lighting systems by evaluating the performance of conventional fluorescent lamps compared to Light Emitting Diode (LED) lighting on tugboats. The objective is to assess and compare both lighting types in terms of energy consumption, lighting uniformity, and compliance with international lighting standards set by classification societies. The research adopts the Zonal Cavity Method (ZCM), which involves dividing the interior of the tugboat into three lighting analysis zones: the High-Ceiling Cavity (HCC), High-Rise Cavity (HRC), and High-Floor Cavity (HFC). Each zone was analyzed to determine the required illumination levels based on standardized guidelines, enabling a systematic comparison of lighting performance between the two technologies. Results indicate that LED lighting systems outperform fluorescent lighting in all evaluated aspects. LEDs provided significantly higher energy efficiency and more uniform lighting distribution across all zones of the tugboat. Additionally, LED systems demonstrated better compliance with minimum illumination levels as outlined in international maritime lighting standards. The study concludes that implementing LED lighting can lead to substantial improvements in shipboard energy efficiency, reduced generator load, lower operational costs, and improved environmental sustainability. These findings suggest that maritime operators should consider transitioning to LED systems as a long-term solution for enhancing energy performance. Future research is recommended to explore the integration of LED systems with renewable power sources such as solar energy, and to evaluate the long-term economic and maintenance benefits across different vessel types and operational profiles.

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

This study focuses on analyzing the structural characteristics of a small craft constructed using aluminum alloy compared with sandwich material structure. High speed vessels are designed to address key performance challenges such as vessel motion, engine efficiency, fuel consumption, and cargo capacity. However, to endure extreme wave induced loads, enhancement of vessel’s the structural strength is essential, especially in critical areas like the midship section. Analytical models and probabilistic methods are employed to predict structural performance under both constant and random wave loading conditions. Aluminum alloys are commonly chosen for fast boat construction due to their high strength to weight ratio and corrosion resistance. To evaluate structural behavior, simulations are carried out under varying wave heights and directions, providing insight into how the vessel performs in challenging marine environments. Load analysis is conducted using diffraction theory and the JONSWAP spectrum equation to determine the maximum bending moments experienced by the hull. The results show that both aluminum and sandwich structures exhibit similar reliability thresholds under wave-induced loading, but the sandwich structure consistently performs slightly better, with approximately 0.10% higher reliability. This suggests that sandwich materials offer improved structural integrity, making them the more suitable choice for high-speed small craft operating in wave conditions up to 2 meters. This analysis contributes to a deeper understanding of the reliability and performance of these materials, offering valuable guidance for designing and constructing high Small Crafts that perform efficiently and safely in demanding maritime operations.
