Fishing boats are used in capturing or collecting aquatic resources. As a means of production, the boat should meet various conditions of seaworthiness i.e. good stability, good seakeeping ability and minimum resistance. Those criteria can be identified when the boat size and the hull form are designed. This study investigates the effect of the boat dimension and the hull form on the stability, resistance and seekeeping ability. Various sizes and hull shapes of a 20 GT fishing boat were simulated, and their performances were compared to the IMO standard. The results suggest that the minimum breadth (B) - draft (d) ratio which meets the stability criterion is 2.50, while the ratio of the center of gravity distance from the keel (KG) and the depth (D) of the boat is 0.65. Furthermore, for the boat with a higher B and D ratio, its resistance is relatively smaller. In terms of seakeeping ability, particularly roll and pitch motions, U type bottom performed better than the Akatsuki bottom. Keywords: fishing vessel, sea keeping, ship hull, stability, resistance
Fishing vessels used to catch resources from the sea has to pass some of the regulations from International Maritime Organization for sea-worthiness of the vessel especially about stability, resistance to acquire the highest velocity, and the vessel’s motion. This research discusses the effect of the vessel’s dimension and the hull shape by using the stability standard from IMO.The result shows that the ratio of the B/T which meets the stability criteria is 2.50 with the ratio of KG/H of the vessel is 0.65, with the assumption that the KG and H of the vessel are more than 0.70. Whereas if the resistance ratio B/T is big, the resistance for the vessel will be relatively smaller. In terms of the vessel motion, a vessel with a V-type hull will better than a U-type hull in seakeeping.
Sektor pariwisata adalah salah satu dari banyak sektor yang mendorong pertumbuhan ekonomi yang penting bagi suatu negara. Indonesia, dengan kekayaan alam dan budaya yang dimilikinya dapat menarik jumlah wisatawan, mancanegara maupun nusantara. Raja Ampat merupakan wilayah yang mempunyai beberapa kekayaan keindahan alam, termasuk kelautannya. Dengan perkembangan teknologi sarana transportasi, bermula dari kapal tradisional Pinisi hingga kapal Yacht, untuk itu perlu adanya pelabuhan untuk dapat melayani kapal modern. Penelitian ini dilakukan untuk merencanakan pelabuhan wisata dengan dukungan fasilitas dermaga pesawat terbang air didalamnya. Berdasarkan data kunjungan wisatawan dan kapal yang sandar, digunakan metode proyeksi yang menggunakan regresi linier untuk mengetahui berapa jumlah kedatangan wisatawan dan jumlah kedatangan kapal 5 sampai dengan 20 tahun yang akan datang. Dari hasil proyeksi perencanaan pelabuhan didapatkan peningkatan produksi penumpang yang signifikan mencapai 488%, menjadikan perlunya dilakukan pengembangan dermaga dan fasilitas lainnya yang menyesuaikan dengan perkembangan teknologi sarana transportasi.
The fisheries industry continues to be one of the main contributors to economic growth. The Ministry of Maritime Affairs and Fisheries Republic of Indonesia reports that the total capture fisheries production rises every year. In 2016 it was recorded to produce 6.83 million tons. Comparison of safety records from the fishing industry with other industrial sectors shows that it continues to be the most dangerous occupation with a sizeable margin. The safety and efficiency of fishing vessel fleet activities is highly dependent on the quality of management decisions. The causal relationships from accidents involving fishing vessels are identified through an analysis of emergencies and fishing incidents. The purpose of this study is to improve the safety of shipping by applying the risk of accidents of fishing vessel by using Formal Safety Assessment (FSA) methodology. The result show that Mechanical failure has a highest risk followed by Vessel Foundering, Falling Overboard and Other. With the right control measure the cost can be minimized 10 – 50 %. The cause of accident is caused by human factor. Increasing the safety of the shipping is necessary with increase the competence of human and law enforcement of shipping activities especially.
Tempat pariwisata di Indonesia telah menjadi destinasi yang banyak dikunjungi bagi wisatawan dalam negeri maupun luar negeri. Danau Toba merupakan destinasi wisata prioritas, sehingga pariwisata ini sangat berpotensi untuk dikembangkan sebagai salah satu aset yang digunakan sebagai sumber yang menghasilkan bagi bangsa dan negara. Penelitian ini dilakukan untuk merencanakan desain pelabuhan wisata dan tata kelola pelabuhan di kawasan Danau Toba dengan tersedianya transportasi kapal ferry, kapal wisata, bus air. Perencanaan pelabuhan yang diteliti menggunakan standar fasilitas yang sangat mendukung mengacu pada Petunjuk Teknis Rencana Induk pelabuhan, dan PERMENPAR nomor 3 Tahun 2018 dengan menambahkan beberapa fasilitas untuk seaplane bases dan WIG (Wing in Ground Effect) seperti landasan pesawat amphibi yang mengacu pada U.S Departement Of Transportation, Federal Aviation Administration dalam dokumen Advisory Circular (AC) No.150/5395-1B. Untuk kelengkapan fasilitas di pelabuhan dan seaplane bases digunakan metode Benchmarking dengan mengacu pada pelabuhan ferry dan seaplane bases yaitu dermaga eksekutif Pelabuhan Merak, Singapore cruise center, Harbour Bay Batam, Jantzen Beach Seaplane Bases, Traves Seaplane Bases, Lake Hood Seaplane Bases. Pelabuhan ini direncanakan melalui beberapa tahap pembangunan menggunakan data pengunjung wisatawan dengan proyeksi kunjungan 20 tahun kedepannya. Berdasarkan hasil proyeksi maka jumlah penumpang terbanyak terjadi pada tahun 2040 dengan jumlah 264.202 orang.
