Abstract

AbstrakKapal ikan digunakan dalam penangkapan atau pengumpulan sumber daya perairan. Sebagai sarana produksi, kapal ikan harus memenuhi syarat kelayakan, yang diantaranya adalah memiliki hambatan gerak yang minimum, sehingga bentuk geometri pada lambung kapal dibawah garis air sangat banyak berpengaruh pada berbagai aspek. Salah satu dari pengaruh dari bentuk geometri lambung kapal adalah perilaku gerak kapal dan hambatan yang terjadi pada kapal. Perilaku gerak kapal dan hambatan inilah yang mempunyai dampak terhadap performa kapal.

Abstract

Piping installation is a unified series of pipes or systems to drain fluid to the desired place by using pipes according to specifications. The piping system is usually equipped with components such as valves, flanges, elbows, branches, nozzles, reducers, supports, insulation and others. The Department of Marine Engineering is one of the majors at the Bengkalis State Polytechnic with facilities and infrastructure, one of which is Pipe and Plate Workshop. The production activities and the teaching and learning process cannot be separated from the plate cutting and painting processes that require compressed air and O2. For the effectiveness of the activities in the Pipe and Plate Workshop, a system for installing compressed air and O2 is carried out. Then the pipe installation system is tested based on the needs of the work carried out at the Pipe and Plate Workshop. Based on the test results on the air pipe installation system, the pressure drop at the outlet valve to the inlet pressure is obtained, namely outlet 1 of 0.1 bar, outlet 2 of 0.3 bar and outlet 3 of 0.4 bar. For the O2 pipe installation system, it is found that the output pressure drop (outlet) to the inlet pressure is large, namely outlet 1 of 0.38 kg/cm2 and outlet 2 of 0.51 kg/cm2.

Abstract

Planning a ship's interior is much the same as planning the interior of any other land-based structure. One thing that distinguishes ships is their corrosive environment due to large waves, storms, and other external disturbances. The shape of the space also distinguishes them, such as the distinctive ship shape, small or confined spaces, and sometimes even more irregular shapes such as curved ones. Narrow or confined spaces may be necessary in certain situations to meet the needs of the crew or passengers for living, working, and resting during voyages, which can sometimes last for long periods, even months. Therefore, the interior spaces of a ship must meet the aforementioned requirements.
