Abstract
Kapal adalah sebuah hasil teknologi yang memiliki berbagai macam sistem yang kompleks dan rumit. Pada saat kapal bergerak dengan kecepatan tertentu, maka akan mengalami gaya hambat dari air, dan untuk mengatasi gaya tersebut diperlukan suatu gaya dorong yang cukup besar dari sistem penggeraknya. Propulsor adalah salah satu bagian dari sistem propulsi kapal, sampai saat ini efisiensi propeller masih sangat kecil. Aliran fluida yang mengalir setelah propeller dapat menyebabkan losses sehingga mengurangi efisiensi, maka dilakukan modifikasi penambahan sayap/fin pada bagian cap propeller. Pada Tugas Akhir ini dibahas mengenai analisa permasalahan diatas melalui pemodelan menggunakan simulasi komputer dengan bantuan software CFD (Computational Fluid Dynamics) dan melalui percobaan towing tank sebagai validasi dari pemodelan CFD. Penggunaan simulasi CFD ini sangat tepat karena perancangan masih dalam tahap conceptual design, sehingga dapat dilakukan berbagai macam-macam variasi yang tentu saja menghemat waktu dan biaya. Sehingga dari sini dapat dilakukan analisa terutama efektifitas penambahan pemasangan sayap/fin pada hub-cap.

Ship is a technology which is has many difficult and complex systems. When a ship is moving with valuable speed it will have thrust force from the water. To fight that force it needs a large number of thrust forces from the propulsion. Propulsor is a part from ship propulsion system which is has small propeller efficiency at the present time. Fluid flow after the propeller caused losses that make efficiency decreased. So, it needs to make a modification in cap propeller area. In this final project will analyze about how to decreasing losses with modeling in computer simulation on CFD (Computational Fluid Dynamics) program and also with towing tank experiment as the validation from simulation on CFD's. Using this CFD simulation is the right choice because design step is still on conceptual design. So, it can make variation perform which is make time and cost more efficient. From this CFD simulation will have a result about effect analyzing of putting a fin in the hub-cap.
