Abstract

many industrial diesel engines are used as the main engine of the ship. Apart from being relatively cheaper, the availability of industrial engine is also very abundant, and the repair process is also not too complicated. However, when viewed from the SOLAS regulations related to the main requirements for a ship propulsion engine, it must also be considered, because it operates at sea, so that ship engines must be tougher than industrial engines, especially related to engine performance when experiencing rolling and trim. The purpose of this research is to test the feasibility of industrial diesel engines being operated on ships. By using a water-cooled single-cylinder diesel engine which is commonly used in small ships. The experimental method was used in this research to obtain optimal results according to the conditions in the field, the engine was made in three variations, namely the normal condition (without inclination angle), the rolling condition of 150, and the trim condition of 50 which complies with SOLAS regulations related to the inclination angle. The results of the research obtained torque, Specific Fuel Consumption (SFC), and engine thermal efficiency in various engine variations. The highest torque is in the condition of the 150 rolling engine, which is 13.87 N.m. The lowest SFC is in the condition of the 150 rolling engine, which is 194 gr/kW.h. and the highest thermal efficiency was also obtained at the condition of the 150 rolling engine, namely 44.9%. The higher the engine speed, the higher the engine performance value in rolling 150 conditions, and the 50 trim conditions experience an increasing trend, but in low rotation conditions (750 Rpm) the performance decreases. Seeing the results obtained, a water-cooled single-cylinder diesel engine can be used as a small boat propulsion engine.

Abstract

Mayoritas kapal kapal nelayan di Indonesia khususnya yang berukuran 30 GT masih memiliki banyak kekurangan seperti kapasitas muatan yang sedikit, jarak tempuh pelayaran yang relatif pendek, desain kapal yang masih kurang ekonomis dan boros bahan bakar serta jumlah armada yang masih sangat sedikit dibandingkan dengan potensi perikanan yang melimpah di laut Indonesia khususnya wilayah pengelolaan perikanan Republik Indonesia (WPP-RI) 713 sehingga mendasari pentingnya dilakukan modernisasi kapal nelayan tradisional. Ukuran utama kapal diambil dari data satu kapal ikan yang terdaftar pada Biro Klasifikasi Indonesia. Desain kapal ini dilakukan dengan bantuan software Maxsurf Modeler dan AutoCAD student version. Adapun perencanaan mesin utama dilakukan dengan bantuan software Maxsurf Resistance dengan menggunakan metode perhitungan hambatan van Oortmerssen sehingga didapat kebutuhan daya mesin sebesar 99.733 HP setelah ditambah margin 15%. Kemudian dipilihlah mesin dengan Merk Yanmar dengan daya sebesar 110 HP. Dari hasil penelitian didapatkan hasil desain lines plan dan general arrangement kapal ikan multipurpose 30 GT dengan alat tangkap purse seine dan squid jigging yang dilengkapi dengan mesin Yanmar bertenaga 110 HP.
