Abstract

The fishing boats used by fishermen on Puger Beach generally still use traditional wooden fishing boats, which were modified from the previous boat design. But over time, the availability of wood decreases. So it is necessary to have alternative basic materials for the manufacture of fishing vessels. An alternative that can replace wood as the basic material for making fishing boats in Puger is fiberglass. Fishing vessels in Puger have varied sizes so it is necessary to analyze the optimum vessel size to operate in Puger. In maintaining ship safety and shipworthiness, a comparison between several parameters of existing fishing vessels is needed. By using the optimization method and then analyzed so that the optimal ship size parameters are obtained. So the optimization results from the ship model in Puger are for a length (L) of 15.57 m, a width (B) of 4.34 m, a ship's height (H) of 1.49 m, and a ship's draft (T) of 0.56 m. From the optimal size of the vessel, then a drawing of the shape of the hull of a fishing vessel made of fiberglass is carried out. The evaluation carried out is the ship's performance such as resistance, stability, and ship seakeeping. So that in determining the shape of the hull which has the characteristics of resistance, stability, and good seakeeping, the ship is in accordance with Puger. So that it can improve and increase the performance of the fishing boats with the aim of the results of this study being to provide recommendations for improving the design of traditional fishing boats in the waters of Puger, Jember Regency

Abstract

ABSTRAKPantai Selatan yang berada di kawasan Kecamatan Puger memiliki luas perairan yang sangat luas. Hal ini menjadi peluang bagi masyarakat sekitar sebagai ladang usaha para nelayan. Mayoritas mata pencaharian dari penduduk di kawasan pesisir Kecamatan Puger adalah seorang nelayan. Permasalahan yang ada di Kecamatan Puger terkait sosial budaya dan ekonomi. Perputaran pendapatan nelayan seringnya membengkak pada kebutuhan bahan bakar mesin. Rata-rata perahu nelayan di Desa Puger Wetan menggunakan motor penggerak yang dilengkapi dengan alat tangkap. Motor penggerak yang digunakan masih secara manual dalam menghidupkannya. Dalam melangsungkan hidupnya para nelayan di Desa Puger Wetan Kecamatan Puger mengirimkan hasil tangkapannya untuk pasar regional dan nasional. Oleh karena itu dibutuhkan sistem baru untuk meningkatkan hasil produksi perikanan Puger yang dapat meningkatkan efektivitas produksi namun diharapkan mampu menumbuhkan industri perikanan dan mengurangi kecenderungan perpindahan tenaga kerja yang berlebihan, termasuk menghasilkan produk sesuai karakteristik wilayah sehingga dapat memiliki akar yang lebih kuat pada kegiatan ekonomi pedesaan. Sehingg dilakukan sosialisasi dan pelatihan bagi para nelayan mengenai penggunaan mesin Stater rotary. Kegiatan ini bertujuan untuk meningkatkan wawasan para nelayan mengenai perkembangan teknologi. Kegiatan ini dilaksanakan pada tanggal 27 Agustus 2022 hingga 30 September 2022. Berdasarkan hasil yang dilakukan, para nelayan merasa tertarik dengan penggunaan mesin stater rotary guna penunjang kegiatan menangkap ikan. Hal ini dikarenakan dengan penggunaan mesin stater rotary ini dapat menurunkan 50% penggunaan bahan bakar daripada penggunaan mesin sebelumnya. Kata kunci: mesin stater rotary; kapal 3 GT; nelayan ABSTRACTThe South Beach which is in the Puger District area has a very wide water area. This is an opportunity for the surrounding community as a business field for fishermen. The majority of the livelihood of residents in the coastal area of Puger District is a fisherman. The problems in Puger District are related to socio-cultural and economic. The income of fishermen often swells to the need for engine fuel. The average fishing boat in Puger Wetan Village uses a motor that is equipped with fishing gear. The driving motor used is still manually turning it on. In carrying out their lives, fishermen in Puger Wetan Village, Puger District, send their catches to regional and national markets. Therefore, a new system is needed to increase the production of Puger fishery which can increase production effectiveness but is expected to be able to grow the fishing industry and reduce the tendency of excessive labor migration, including producing products according to regional characteristics so that they can have stronger roots in rural economic activities. So that socialization and training were carried out for fishermen regarding the use of the Starter Rotary machine. This activity aims to increase the knowledge of fishermen about technological developments. This activity was carried out from 27 August 2022 to 30 September 2022. Based on the results carried out, the fishermen felt interested in using the starter machine to support fishing activities. This is because the use of this rotary starter engine can reduce fuel use by 50% compared to the use of the previous engine. Keywords: machine of stater rotary; fishing vessel of 3 gt; fisherman.

Abstract

ABSTRACTThe presence of biofouling has an impact on the ship’s performance, which is reduced to require more fuel, in the end, it contributes significantly to cost increases. Biofilms provide a suitable substrate for the growth of microorganisms. Ship hull as a substrate for biofilms has many kinds of material. Steel, wood, laminated bamboo, and fiber are often used for ship hulls. Different material makes different characteristics of substrate for biofilms. The aim of this research is to determine the growth rate of biofouling in each shipbuilding material and to find out which vessel material is suitable for use in the Bali Strait. The experiment was located in Boom Marina, Banyuwangi. The materials used in this research are wood, laminated bamboo, and fiber. The daily growth rate (DGR) is calculated every week of observation. Wood had the most biofouling with a DGR of 2,646 g/day. Laminated bamboo had the least biofouling in this research after 2 months of immersion with a DGR of 0,086 g/day. Keywords: Biofouling, shipbuilding material, daily growth rate.

Abstract

Puger is one of the areas in Jember Regency whose main commodity comes from the sea. Fishermen need means of transportation to support them in catching fish in the sea. Puger District is also famous for its beaches and is the largest fish producer in Jember Regency. Therefore, fishing boats needed that have good performance following the characteristics of Puger waters. Puger waters have a strong trend mark with high sea currents and waves. Jukung boats are ships that are often used by fishermen in Puger. However, the process of making Jukung boats still uses conventional methods, which rely on knowledge/experience from their ancestors. The basis for making Jukung ships is mostly still not the correct procedures such as designing main dimensions, designs, and others. The impact of this affects the level of optimization of the feasibility of fishing vessels. Based on this, further studies are needed to evaluate the stability of the Jukung. This evaluation expected to be a reference regarding the level of security and comfort of the Jukung boat for the safety of the fishermen. The method used in evaluating stability is using the Krylov method. Based on the test results obtained stability are positive. so that the ship has the ability to be able to return to the even keel position after a trim/heel.

Abstract

Ships are a mode of transportation that is often used by the community as a link between the islands. People generally use the ferry as a mode of crossing in addition to the economical price but also comfort is still preferred. But in recent years, researchers have often heard cases of shipwrecks. Especially ship crossing accidents caused by overturned ships. Based on this, prevention is needed to reduce the number of ship accidents in the future. One of the keys that can be taken is to improve the technical analysis before the ship is designed. One such analysis related to the ship is seakeeping ship. The method used in this study is to use strip – theory method through OSM program. This method is one of the commonly used methods because it calculates the 3D model into 2D. The results showed the effect of the use of Bilge keel on the ferry Ro-Ro tested with conditions x0, x1, x2, and x3 on the condition of the stationary ship with a wave height of 1,5 m and heading 90o. The addition of Bilge keel is able to reduce the resonance of roll motion up to 58% in conditions of variation x1, 61% in variation x2, and 67% in conditions of variation x2. Therefore, the installation of bilge keel has a significant effect on the rolling of ferry Ro-Ro.
