“…The ship specifications are in more detail as shown in Table 1. The secondary sail data used is a triangular shaped sailing ship from the archipelago that operates in the Cirebon Sea [22] as shown in Figure 1. The selection of the type of sail shape is because according to Anwar et al, [17] the contribution of the additional speed from the triangular sail is 4.4 knots or equal to 44%.…”

The fisheries sector is one of the potential sectors that contribute to Indonesia's state income, but it has often been neglected. Almost all fishing boats still use diesel engines as the main power source to propel the boat. The use of this type of fuel has an impact on increasing the level of air pollution such as CO2, SO2, and NOX in the atmosphere. However, research to reduce ship pollution, especially the combination of propulsion system for fishing boats using engines and sails, is rarely carried out. This study aims to determine the hydrodynamic characteristics of fishing vessels on the north coast of Java due to the application of numerical variations in laying sails using Computational Fluids Dynamics (CFD). The numerical simulation results show that the placement of sails in each model variation results in a change in the fluid flow pattern from bow to stern which can contribute to fuel efficiency. From the comparison of the three models, the most effective placement of sails is at the bow of the ship.

This article aims to review the existence of coastal cities based on structuralism theory to understand the urgency of studying maritime history in the archipelago. The archipelago has a vast ocean expanse that allows interaction between individuals in maritime activities, namely shipping, and trade. On the other hand, it also had consequences; the arrival of foreigners to the archipelago significantly impacted maritime conditions, especially in forming coastal city structures and several other supporting elements. The study used the historical method. The stages were heuristics, source criticism, interpretation, and historiography. Of all these things, this article discusses three structuralism ideas by Fernand Braundel and their relations to studying maritime history in the archipelago, including longue durée, conjoncture, and evenementiel.

“…Umumnya terbuat dari kayu dan dewasa ini juga dikembangkan dengan bahan fibreglass (Imron et al 2020) karena bahan material pembuatannya lebih mudah didapatkan (Yulianto et al 2013;Ariesta et al 2018). Sampan maupun jukung merupakan armada khas bangsa Nusantara (Haddon 1920;Fiqri 2020) sebagai bentuk kearifan lokal (Imron et al 2020) yang tetap eksis hingga hari ini.…”

Nelayan tradisional dengan armada sampan dan jukung selalu memobilisasi armada mereka di pantai ketika melakukan operasi penangkapan ikan dengan menggunakan gelindingan konvensional yang terbuat dari potongan kayu (log). Hal ini dilakukan untuk memperpanjang umur teknis armada. Namun, dibutuhkan waktu dan tenaga yang relatif besar apabila menggunakan gelindingan konvensional. Penelitian ini bertujuan untuk merancang, membangun dan menguji penggunaan “Gelindingan Inovasi” yang digunakan untuk memobilisasi sampan dan jukung. Penelitian dilakukan di pangkalan nelayan Ketapang Lampu, Pengambengan, Jembrana, Bali, bulan Maret-Desember 2022. Data yang dikumpulkan berupa profil kegiatan perikanan di lokasi penelitian serta teknis penggunaan gelindingan konvensional yang didapatkan dengan pengamatan langsung dan wawancara. Selanjutnya dilakukan Focus Group Discussion dengan perwakilan nelayan untuk melakukan konsultasi terhadap rancangan Gelindingan Inovasi yang digagas. Kegiatan konstruksi dilakukan di bengkel bubut setempat. Selanjutnya, dilakukan ujicoba penggunaan ‘Gelindingan Inovasi’ untuk memobilisasi sampan/jukung milik nelayan. Gelindingan Inovasi yang dibangun tetap mempertahankan pola kebiasaan nelayan dalam memobilisasi armadanya. Konstruksi Gelindingan Inovasi ini terdiri atas roda yang terbuat dari bahan kayu (log) yang diberi as roda (shaft) dan dudukan untuk menempatkan sampan/jukung. Hasil pengujian menunjukkan terdapat peningkatan kecepatan mobilisasi yang siginifikan antara gelindingan konvensional dengan ‘Gelindingan Inovasi’. Kecepatan rata-rata mobilisasi dengan gelindingan konvensional 1,41-3,16 m/menit menjadi 9,38-29,75 m/menit dengan Gelindingan Invoasi (peningkatan 6-9 kali lipat).
