Abstract

Dalam mendesain sebuah kapal, terdapat beberapa peraturan dan regulasi yang harus dipenuhi. Akan tetapi pada praktiknya, kapal yang memenuhi regulasi saja belum cukup baik. Dalam membangun kapal harus dipikirkan sedetail mungkin sehingga kapal tidak hanya layak, akan tetapi juga efektif dan efisien selama operasional. Penelitian sebelumnya telah melakukan optimisasi hingga didapatkan ruang muat yang berlebih. Pada penelitian kali ini optimisasi lambung akan dilakukan untuk mengurangi nilai hambatan kapal dengan metode Exhautive Search. Proses optimisasi dilakukan dengan mengurangi panjang kapal dan merubah bentuk lambung kapal pada domain optimisasi. Variabel yang digunakan adalah panjang pemotongan, dan lebar waterplane pada waterline dan station yang ditentukan. Perubahan geometri lambung tersebut akan merubah koefisien utama kapal seperti Block Coefficient (Cb), Prismatic Coefficient (Cp), Waterplane Coefficient (Cwp), dan Longitudinal Centre of Buoyancy (LCB). Koefisien tersebut berpengaruh terhadap komponen-komponen hambatan sehingga nilai hambatan akan berubah. Pada penelitian kali ini, didapatkan hasil hambatan optimal sebesar 155.7 kN. Nilai tersebut menandakan bahwa optimisasi berhasil mengurangi nilai hambatan kapal sebanyak 3.8%. Selain itu, ruang muat pada kapal setelah dilakukan optimisasi sebesar 8182.37 m3, sehingga optimisasi mencapai 99.85% dari target volume.

While designing a ship, there are various rules and regulations that must be fulfilled. However, in practice, a ship that merely complies with regulations is not necessarily optimal. Ship design must be carefully considered so that the vessel is not only seaworthy, but also effective and efficient during operation. Previous studies have performed optimization and obtained excessive cargo space. In this study, hull form optimization is conducted to reduce ship resistance using the Exhautive Search. The optimization process is carried out by reducing the ship length and modifying the hull form within the optimization domain. The variables used are the length reduction and the waterplane breadth at specified waterlines and stations. Changes in hull geometry affect the main ship coefficients such as the Block Coefficient (Cb), Prismatic Coefficient (Cp), Waterplane Coefficient (Cwp), and the Longitudinal Centre of Buoyancy (LCB). These coefficients influence the resistance components, leading to variations
in the total ship resistance. The results show that the optimal ship resistance obtained is 155.7 kN, indicating a reduction of 3.8% compared to the existing ship resistance. In addition, the cargo hold volume after optimization is 8182.37 m³, meaning that the optimization achieved 99.85% of the target volume.
