Abstract

The Pinisi is a traditional Indonesian ship recognized as a maritime cultural masterpiece and remains widely utilized, particularly in liveaboard tourism. The increasing demand for sustainable and innovative energy solutions in the tourism and maritime industries highlights the relevance of adopting solar cells as an alternative energy source for lighting on these ships. Solar cells, primarily made from silicon, efficiently convert solar radiation into electrical energy. This study evaluates the feasibility of using solar cells to power lighting systems on Pinisi ships operating in the Selayar Islands. Solar radiation data from NASA Surface Meteorology was utilized to estimate the optimal power output of solar modules. The analysis indicates that 10 solar cell modules can generate an energy output of 19.480 kWh, sufficient to meet the ship's lighting requirements. Configurations were optimized for different decks, ensuring efficient energy distribution while maintaining sustainability. The findings demonstrate that implementing solar cells on Pinisi ships not only fulfills their energy needs but also supports the maritime tourism industry by providing an eco-friendly and innovative energy solution. This approach contributes to the preservation of maritime heritage while addressing contemporary environmental challenges.Keywords: Pinisi ship, solar cells, energy conversion, maritime tourism innovation

Abstract

Kapal merupakan kendaraan air, baik berpenggerak maupun tidak berpenggerak. Lebih rinci, definisi kapal sesuai Peraturan Menteri Perhubungan Nomor 7 Tahun 2013 Pasal 1 Butir 3 adalah kendaraan air dengan bentuk dan jenis tertentu, yang digerakkan dengan tenaga mesin, tenaga mekanik, energi lainnya, ditarik atau ditunda, termasuk kendaraan yang berdaya dukung dinamis, kendaraan di bawah permukaan air, serta alat apung dan bangunan terapung yang tidak berpindah-pindah. Kapal dibangun dari pelat yang dirangkai dengan kawat las. Di dalamnya terdapat berbagai macam material dan komponen, termasuk pelat dan kawat las yang digunakan. Material dan komponen lainnya adalah mesin induk, mesin bantu, permesinan geladak, pompa-pompa, perlengkapan lambung (hull outfittings) dan perlengkapan permesinan & kelistrikan lainnya. Untuk kapal dengan notasi E, selain diawasi pembangunannya, material dan komponennya pun harus bersertifikat. Sebagian besar material dan komponen utama yang digunakan pada kapal bangunan baru di Indonesia diproduksi di dalam negeri, kecuali mesin utama dan mesin bantu yang masih impor. Hal ini tentu menjadi kendala dalam melakukan sertifikasi material dan komponen tersebut, khususnya dimasa Pandemic Covid-19. Tulisan ini menjelaskan mengenai metode-metode yang dapat digunakan untuk melakukan sertifikasi material dan komponen kapal di masa Pandemic Covid-19 untuk kapal-kapal yang diklaskan ke BKI.
Optimizing Generator Power Usage Through LED Lighting Distribution on Tugboats: A Case Study of a 26.80-Meter Vessel Suardi, Suardi; Pratama, Brian Yoga; Pawara, M Uswah; Yosefan, Andreyano; Anugerah, Andi Nurwahid; Abdurrahman, Luthfi; Tasrief, Muhdar; Klara, Syerly

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.
