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

Balikpapan Bay connects Balikpapan City with the new capital city of the Republic of Indonesia (IKN). Currently, many community activities in Balikpapan Bay include functioning as a crossing, loading and unloading, and fishing. Balikpapan Bay also offers an unforgettable water tourism experience with many intriguing attractions for all ages, such as water slides and diving. IKN is utilized by the development of marine transportation to create marine tourism potential in Balikpapan Bay. The purpose of the research project is to build a tourist phinisi ship that allows tourists from within and outside the country to spend their free time on board and enjoy the splendor of Balikpapan City and IKN with a cultural concept. Phinisi will be equipped with lodging, museums, cafes, and restaurants, all depending on the design of the boat. The research stages include designing a general arragement that produces data in the form of main dimensions, hull form coefficients, lines plans, general arrangements, 3D designs, and interior rooms. The research method used is the parentship approach. The main dimensions obtained in my final assignment include; loa = 55 m, B = 9 m, H = 5 m, T = 3.5 m, Vs = 9 Knots, Crew 11 people, passengers = 15 people

Abstract

This study examines the motion response and onboard comfort of a Ro-Ro ferry under varying wave directions and speeds using the Response Amplitude Operator (RAO), Motion Sickness Incidence (MSI), and motion-induced interruptions (MII) as evaluation parameters. Simulations were conducted using Maxsurf Motion software with wave heights of 3 m and 3.5 m and encounter angles of 0° (following seas), 90° (beam seas), and 180° (head seas) at vessel speeds of 0 and 12 knots. The MSI was assessed using both simulation results and empirical calculations, whereas the MII was evaluated according to the ISO 2631 standards at three onboard locations: the passenger, navigation, and vehicle decks. The RAO results indicate that the vessel met the NORDFORSK (1987) motion criteria under following and head seas but exceeded the roll limits in beam seas. The MSI values remained within the moderate comfort range, except under head seas at 12 kn, where the values approached the alert thresholds. The MII remained within acceptable levels under most conditions, although probable interruption levels were observed on the passenger and vehicle decks during beam sea conditions. Overall, the findings emphasize that wave direction and vessel speed significantly influence motion-induced discomfort and operational performance, underscoring the importance of optimizing route planning and speed to improve passenger safety and seakeeping performance on roll-on/roll-off ferries.

Abstract

Kurangnya perhatian terhadap aspek keselamatan dalam desain kapal ikan, di mana pembuat kapal lebih berfokus pada hasil tangkapan. Analisis bottom slamming dan deck wetness diperlukan untuk menghindari kondisi berbahaya saat menghadapi cuaca buruk. Nilai RAO(Response Amplitude Operator) kapal ikan katamaran perlu untuk diketahu dengan variasi sudut gelombang 0°, 90°, 135°, dan 180° serta menghitung probabilitas deck wetness dan bottom slamming. Perhitungan RAO dilakukan menggunakan metode optimasi dengan perangkat lunak Maxsurf pada variasi muatan 25% DWT ,50% DWT, dan 100% DWT. Hasil penelitian menunjukkan bahwa amplitudo heave tertinggi terjadi pada kondisi 100% DWT, kecepatan 6,45 knot, dan sudut gelombang 0°, sebesar 0,131 meter. Amplitudo pitch tertinggi adalah 2,02 derajat pada kondisi yang sama, sedangkan amplitudo roll tertinggi terjadi pada 50% DWT, kecepatan 6,45 knot, dan sudut gelombang 90°, sebesar 3,43 derajat. Probabilitas deck wetness sebesar 0,24% dan bottom slamming sebesar 0.0000000014996%, keduanya telah memenuhi standar NORDFORSK 1987. Kata Kunci: Bottom Slamming ; Deck Wetness; DWT ; Probabilitas; RAO
