Abstract

Kapal merupakan salah satu jenis transportasi yang sering digunakan di Indonesia karena indonesia termasuk negara kepulauan terbesar didunia. Tidak hanya digunakan sebagai transportasi, beberapa jenis kapal juga berfungsi sebagai alat untuk menjaga dan mempertahankan kedaulatan negara terutama disektor maritim.Untuk memperkuat armada laut, perlu dilakukan pengembangan dan peningkatan kualitas kapal. Kapal cepat memiliki tahanan kapal yang besar akibat kecepatannya. Penelitian ini bertujuan untuk mengurangi tahanan gelombang pada Kapal Patroli Lepas Pantai dengan menambahkan Combined Wedge-Flap. Alat ini terpasang pada bagian buritan di bawah transom kapal. Pada penelitian ini akan disimulasikan berbagai variasi dengan metode CFD menggunakan aplikasi NUMECA FineMarine. Parameter dimensi dari CWF yang divariasikan adalah lebar CWF pada angle 2° dan 2% Lpp. Total variasi yang akan disimulasikan adalah 3 variasi yaitu 80% BT, 90% BT, dan 100% BT. Selain itu, combined wedge-flap disimulasikan pada kecepatan 15 knot, 17 knot, dan 20 knot. Hasil simulasi menunjukan bahwa variasi CWF 80% BT adalah variasi CWF yang paling baik dalam mengurangi resistance yaitu sebesar -2,17% atau 1,52 kN pada kecepatan 15 knot, mengurangi resistance sebesaar -2,8% atau 2,54 kN pada kecepatan 17 knot, dan mengurangi resistance sebesar -1,82% atau 2,79 kN pada kecepatan 20 knot. Pada penelitian ini, juga dianalisis kebutuhan daya akibat pemasangan CWF hasilnya menunjukan pengurangan daya akibat penambahan CWF 80%BT pada kecepatan 15 knot mampu mengurangi kebutuhan daya yaitu sebesar -3.29% atau 40 kW, pada kecepatan 17 knot mampu mengurangi kebutuhan daya yaitu sebesar -3,08% atau 56 kW, dan pada kecepatan 20 knot mampu mengurangi kebutuhan daya yaitu sebesar -3.26% atau 120 kW.

Ships are a type of transportation that is often used in Indonesia because Indonesia is one of the largest archipelagic countries in the world. Not only used as transportation, several types of ships also function as tools to maintain and maintain state sovereignty, especially in the maritime sector. To strengthen the maritime fleet, it is necessary to develop and improve the quality of ships. Fast ships have large ship resistance due to their speed. This research aims to reduce wave resistance on Offshore Patrol Vessels by adding a Combined Wedge-Flap. This tool is installed at the stern under the ship's transom. In this research various variations will be simulated using the CFD method using the NUMECA FineMarine application. The dimensional parameters of the CWF that were varied were the width of the CWF at an angle of 2° and 2% Lpp. The total variations that will be simulated are 3 variations, namely 80% BT, 90% BT, and 100% BT. In addition, combined wedge-flap is simulated at speeds of 15 knots, 17 knots, and 20 knots. The simulation results show that the 80% BT CWF variation is the best CWF variation in reducing resistance, namely -2.17% or 1.52 kN at a speed of 15 knots, reducing resistance by -2.8% or 2.54 kN at a speed of 17 knots, and reduces resistance by -1.82% or 2.79 kN at a speed of 20 knots. In this research, the power requirements due to the installation of CWF were also analyzed. The results showed that the reduction in power due to the addition of CWF 80%BT at a speed of 15 knots was able to reduce power requirements by -3.29% or 40 kW, at a speed of 17 knots it was able to reduce power requirements by -3. .08% or 56 kW, and at a speed of 20 knots it can reduce power requirements by -3.26% or 120 kW.
