Abstract

Laut Jawa merupakan salah satu perairan di Indonesia dengan lalu lintas terpadat. Akan tetapi, TNI AL memperkirakan bahwa masih banyak ranjau aktif peninggalan Perang Dunia II yang terdapat di Laut Jawa. Hal ini dapat menimbulkan potensi bahaya bagi kapal yang melintas di perairan tersebut. Maka dari itu, perlu dilakukan operasi sapu ranjau di wilayah Laut Jawa untuk menciptakan kondisi perairan yang aman. Tujuan dari Tugas Akhir ini adalah untuk merancang kapal sapu ranjau dengan operational requirement berupa kecepatan dinas, kecepatan penyapuan ranjau, rute operasi, dan payload. Kapal memiliki kecepatan dinas 14 knot dan kecepatan penyapuan ranjau 4 knot. Rute operasi kapal meliputi perairan Laut Jawa bagian timur hingga bagian barat, dengan basis operasi berada di Pangkalan Komando Armada II TNI AL, TBBM Tuban, TBBM Semarang, Dermaga Pelabuhan Cirebon, dan Pangkalan Komando Armada I TNI AL. Payload pada kapal berupa amunisi, persenjataan, perlengkapan menyelam, kru sapu ranjau, TNT, dan Shrimp ROV. Penentuan ukuran utama kapal dilakukan dengan Geosim Procedure, dengan ukuran utama yang didapatkan adalah LPP = 76,2 m, B = 12,972 m, H = 6,725 m, dan T = 3,5 m. Perhitungan hambatan kapal dilakukan dengan Metode Holtrop dan didapatkan nilai hambatan sebesar 110,1 kN. Perhitungan freeboard minimum dilakukan dengan metode ICLL dan didapatkan nilai freeboard minimum sebesar 1084,606 mm serta nilai bowheight minimum sebesar 3215,105 mm. Freeboard sesungguhnya yang dirancang pada kapal adalah 3,225 m. Perhitungan trim dilakukan berdasarkan SOLAS 2009, di mana trim tidak boleh melebihi ±0,388 m pada 6 loadcase. Perhitungan stabilitas dilakukan dengan teori Sarchin & Goldberg. Seluruh perhitungan tersebut telah memenuhi persyaratan yang ditentukan. Biaya pembangunan kapal adalah Rp 123.383.206.494. Harapannya adalah dengan adanya kapal sapu ranjau yang beroperasi menyapu ranjau laut di perairan utara Pulau Jawa, kapal yang beroperasi di perairan utara Pulau Jawa bisa melewati Laut Jawa dengan aman tanpa ada ancaman dari ranjau laut yang masih tertanam di perairan utara Pulau Jawa. ================================================================================================================ Java Sea is one of the seas with the heaviest traffic in Indonesia. However, the Indonesian Navy predicts that active sea mines that was part of World War II’s remains still exist within the waters. This could be potentionally destructive to all the vessels passing by. Thus, a minesweeper vessel must be made to keep the vessels and the waters safe. The objective of this thesis is to design a minesweeper vessel with an operational requirement that consists of service speed, minesweeping speed, operation route and payload. The designed vessel will have a service speed of 14 knots and a minesweeping vessel of 4 knots. The route will start from the very east of Java Sea and will carry along up to the furthest west. The base of the designed vessel throughout this operation would be at Naval Base of the Second Fleet, TBBM Tuban, TBBM Semarang, Cirebon Port, and Naval Base of the First Fleet in that respective order. The payload of the vessel consists of ammunition, combat systems, diving equipments, minesweeping crew, TNT, and a shrimp ROV. The main dimension of the designed vessel was obtained through Geosim Procedure which resulted a Lpp of 76,2 m, Breadth of 12,972 m, Height of 6,725 m, and Draught of 3,5 m. The resistance of the designed vessel was obtained with Holtrop Method which resulted 110,1 kN. The calculation of freeboard was btained with ICLL’s regulation, in which the minimum freeboard would be 1084,606 mm and the minimum bow height would be 3215,105 mm. Though, the designed minesweeping vessel has a freeboard of 3225 mm. The trim calculations are done based on SOLAS 2009, where the trim must not exceed ±0,388 m for 6 loadcases. The stability calculations are done with Sarchin&Goldberg’s method. The approximate building cost of the designed ship is Rp. 89.696.344.195,12,-. It is hoped that with the designed minesweeping vessel, the vessels that sails through Java Sea can soar without any chance of explosion from the active sea mines in the depths of Java Sea.
