Abstract

Based on data from the Sumenep Health Office, the number of positive confirmed cases of Covid on Talango Island was 9 people and 1 person died. One of the reasons is that there are no corona treatment facilities on the island, so they have to be referred to the Sumenep Regency hospital by boat. In this study, the design of a speed boat ambulance specifically for Covid-19 patients with a catamaran hull type. The purpose of the speed boat ambulance design is to handle island patients, especially Covid-19 cases during sea journeys to Sumenep Hospital with adequate facilities. The research method is carried out by determining the main size of the ship using the sister ships method, then proceeding with drawing lines plan, calculating ship resistance along with determining engine power, and general arrangement. The results obtained are in the form of the main size of the ship in the form of a Catamaran ship type; LOA : 13.0 m; B : 7.0 m; H : 2.0 m; T : 1.2 m; Vs : 16 knot. Has 3 accommodation rooms, including a patient room for 2 people; Medical staff room with 1 doctor, 2 medical staff and 2 patient's families; The wheelhouse with 2 crew members.

Abstract

Operation of crewboats in areas suffering from petroleum to be free from accidents. Therefore, the ease of operation of the ship is the main thing. The position of the ferry room and control room behind the PSV ship with the VS 493 series and the crewboat produced by Chantiers Allais is considered to be able to increase the comfort of the passenger room and the control room with only one maneuver position can facilitate the operation of the ship. The crewboat ship KCT 1902 is a ship already operating in an oil drilling area with a ferry space in front and a cargo deck at the rear. To be able to participate in the tender again, this ship must have a passenger room in the back and a cargo deck in front. The purpose of this thesis is to analyze the transfer of passenger space from the technical side and from the economic side. From the results of technical analysis, there was an increase in weight of 0.56 tons and a significant shift in point. This result led to changes to the ship, but the changes to be faced still have to be made. From the results of the economic analysis, it was found that the capital needed was Rp. 26,669,803,218.01, operating costs per year was Rp. 3,624,750.00 and income per year was Rp. 11,343,105,000.00, a Break Event Point was obtained in the 7th year.

Abstract

Landing Craft Tank (LCT) ships are vessels used to transport large vehicles such as heavy cargo, bulldozers, excavators, dumb trucks, loaders, and other heavy equipment indispensable for construction and mining work. For shipping locations that are transported using a Landing Craft - Tank (LCT) ship, it is a mining location or project location that is on an island or beach and river route which is indeed difficult to reach by ordinary transport vessels. The Landing Craft - Tank (LCT) ship has a broad and flat deck so it can carry heavy equipment and construction materials. The LCT Sarana III ship has a main size of Length Over All = 47.00 m, Breadth Deck = 9.50 m, Draft Design = 2.00 m, Dept = 3.20 m. As a result of this load it will result in load distribution on the LCT ship. With changes in the ship's framing system, there will be a change in voltage characteristics. In each framing system, the maximum stress analysis is carried out with the help of a numerical finite element method (FEM) program. The analysis used is the analysis of static loads originating from the vehicle, the load for each loading condition and the hydrostatic load. The analysis aims to determine the stress characteristics and the greatest stress value of ship construction and to determine the location of the critical point on the ship, based on three variations of loading conditions, namely calm water, sagging and hogging. The results of the analysis and calculations carried out on the LCT model one in calm water conditions of 68 N / mm2, sagging conditions of 76.8 N / mm2, and hogging conditions of 74.1 N / mm2. For model two in calm water conditions of 68 N / mm2, sagging conditions of 74.8 N / mm2, and hogging conditions of 72.6 N / mm2. From the results of the stress values, it can be concluded that all stress values that occur on the ship are still meet the safety factor, both according to the material criteria and BKI standards.

Abstract

Peran galangan kapal Sebelum Pandemi sangat penting di dalam menunjang perekonomian khususnya di sektor transportasi laut, baik untuk pengadaan armada kapal Sebelum Pandemi maupun sebagai sarana perawatan. Kemampuan galangan Sebelum Pandemi baru mampu melayani 50% pekerjaan reparasi dan 30% pekerjaan pembuatan kapal baru dari potensi pekerjaan yang ada. penelitian ini menggambarkan pangsa pasar (market share) dari 5 galangan kapal di Kabupaten Gresik dengan cara membandingkan jumlah potensi pasar galangan Pada Masa Pandemi dan Sebelum Pandemi dengan hasil pekerjaan permintaan reparasi dan bangunan baru galangan-galangan kapal di Kabupaten Gresik. Metode yang kami gunakan dalam penelitian ini adalah metode forecasting terhadap pangsa pasar galangan kapal di Kab. Gresik. Hasil penelitian menunjukkan, pangsa pasar galangan-galangan kapal di Kabupaten Gresik untuk Sebelum Pandemi untuk reparasi galangan kapal a. Pangsa pasar galangan-galangan di Kabupaten Gresik untuk Sebelum Pandemi adalah sebesar 0.31% dari potensi pasar galangan nasional b.Pangsa pasar galangan-galangan di Kabupaten Gresik untuk Pada Masa Pandemi adalah sebesar 0.0071% dari potensi pasar galangan nasional. Dan untuk bangunan baru galangan kapal sebagai berikut a.Pangsa pasar galangan-galangan di Kabupaten Gresik untuk Sebelum Pandemi adalah sebesar 6.92% dari potensi pasar galangan nasional. b.Pangsa pasar galangan-galangan di Kabupaten Gresik untuk Pada Masa Pandemi adalah sebesar 0.0527% dari potensi pasar galangan nasional.

Abstract

The development of science and technology today is growing very fast. This makes students compete to keep up with technological developments in the era of digitalization. Madura State Polytechnic through electric drive laboratory facilities requires practicum supporting equipment. In borrowing instruments for practical needs, data collection and others can be done very easily and quickly. The process of storing or retrieving instruments in the laboratory, taking instruments on a shelf still uses conventional methods. An automated system can be applied to the storage and retrieval process of laboratory instruments to make the process faster, easier, and have high accuracy. This study tries to help solve problems in the instrument storage and retrieval system which is still at the conventional stage to be developed into an online based. From the experiments that have been carried out, the ASR Robot is controlled using a Programmable Logic Controller (PLC) which functions as the main control of the automatic instrument storage and retrieval system. Proximity sensors are used to detect the position of the robot and limit the movement of the robot so that it is accurate to pick up instruments that are in stacked shelves. The ASR robot works by requiring 294.8 Watts of power.
