Abstract


ABSTRACT

As a coastal area, Banyuwangi has a variety of marine potential that can be harness, both in terms of tourism and in terms of fishing. This certainly must be equipped with ships that the design are in accordance with the conditions of the Banyuwangi sea, and the special purpose of the ship. So it is become necessary to test hydrodynamic characteristic of the ship hull. Hydrodynamics testing is one of the engineering subject in the field of naval architecture technology. This field, studies the behavior of the object motion or ships hull that are in the water. The existence and movement of objects in water create a boundary layer where if the boundary layer is wider the consequence is resistance will increase, so that the ship's fuel consumption also increases. The hydrodynamic analysis in this study is based on the observation method of water flow generated by the ship's prototype, and the ship's maneuver conditions. For this reason, in this research, an experimental test equipment for fast boat (tourism) and fishing boat needs to be designed. The equipment is a Mini Circulating Water Channel Tank, this experimental device can help the design stages of fast boats and fishing boats before fabrication, so it is able to minimize design failure. Mini Circulating Water Channel Tank is designed with a length of about 3 meters and a height of 2 meters with a maximum flow speed of 4 m / s and in the upper position will be given a special suspension clamp to provide a feasible simulation of ships sailing on the high seas, so as to provide data accurate regarding the condition of the hull and the behavior of the ship's movements.

Keywords: Mini Circulating Water Channel Tank, Hydrostatic Test.

 

ABSTRAK

 

Sebagai daerah pesisir, Banyuwangi memiliki berbagai macam potensi laut yang bisa dimanfaatkan, baik itu dari segi pariwisata maupun dari segi penangkapan ikan. Hal ini tentu harus di lengkapi dengan kapal-kapal dengan desain yang sesuai dengan kondisi laut Banyuwangi dan tujuan khusus kapal tersebut. Sehingga diperlukannya pengujian hidrodinamis terhadap lambung kapal. Hidrodinamika atau pengujian hidrodinamis merupakan ilmu keteknikan di bidang teknologi perkapalan. Bidang ilmu ini mempelajari perilaku gerakan benda atau kapal yang berada di air. Keberadaan dan pergerakan benda di air menimbulkan apa yang disebut lapisan batas atau boundary layer dimana jika boundary layer semakin lebar maka konsekuensinya adalah besarnya hambatan tenaga penggerak sehingga konsumsi bahan bakar kapal meningkat. Analisa hidrodinamika pada penelitian ini didasarkan pada metode observasi aliran air yang di hasilkan oleh prototype kapal, dan kondisi manuver kapal. Untuk itu dalam penelitian ini, perlu dirancang sebuah peralatan eksperimen pengujian untuk kapal cepat (pariwisata) dan kapal nelayan. Peralatan tersebut adalah Mini Circulating Water Channel Tank, piranti percobaan ini dapat membantu tahap desain kapal cepat dan kapal nelayan sebelum fabrikasi, sehingga dapat meminimalkan kegagalan desain yang disebabkan oleh cacat pada lambung kapal. Mini Circulating Water Channel Tank dirancang dengan ukuran panjang sekitar 3 meter dan tinggi 2 meter dengan kecepatan aliran maksimal 4 m/s dan di posisi atas akan di berikan penjepit bersuspensi khusus untuk memberikan simulasi layak nya kapal berlayar di lautan lepas, sehingga mampu memberikan data yang akurat mengenai kondisi lambung kapal dan perilaku gerakan kapal.

 Kata Kunci: Mini Circulating Water Channel Tank, Uji Hidrodinamika Kapal.
