Abstract

Dalam perencanaan pemilihan ukuran utama kapal (principle dimension) dibutuhkan pengambilan keputusan sesuai dengan kriteria yang telah ditentukan. Pengambilan keputusan yang tepat dan sesuai dengan kriteria yang dibutuhkan akan menjadi rumit apabila dihadapkan pada beberapa kriteria yang saling berhubungan dan harus terpenuhi. Oleh sebab itu digunakanlah logika fuzzy guna membantu dalam penentuan pengambilan keputusan. Dalam perencanaan pemilihan ukuran utama kapal barang pada jurnal ini diberikan beberapa batasan yaitu tinggi sarat maksimal kapal yaitu 6 meter, panjang keseluruhan kapal sekitar 100 meter, dan berat mati kapal kira – kira 3000 ton dan 5000 ton. Setelah dilakukan analisa menggunakan logika fuzzy terhadap data kapal-kapal yang telah dikumpulkam, didapatkan hasil yang menunjukan kapal nomor 16 memiliki nilai keanggotaan satu sehingga masuk dalam kriteria sangat memenuhi.

Abstract

The choice of Duplex Stainless Steel material for oil tanker ship construction is very appropriate because in addition to having good mechanical properties (high tensile and yield strength and toughness) as a ship construction structure, it is also resistant to loads of highly corrosive liquid chemicals. Unlike Mild Steel or Duplex Stainless Steel A, welding and treating Duplex Stainless Steel requires very strict procedures and care must be taken. The choice of welding process, namely a combination of (Flux Cored Arc Welding) and SAW (Submerged Arc Welding) is a welding process that is very suitable for welding ship construction. The welding process is categorized as a semi-automatic and automatic welding process that can increase productivity while speeding up welding work. This paper illustrates the welding of two materials with different specifications, namely Duplex Stainless Steel 2205 plate material and VL D36 plate material, along with practical instructions for welding it up to the things that must be considered regarding the handling procedure. In welding Duplex Stainless Steel 2205 plate material it is very important to keep the heat input in the range of 0.5-2.5 kj / mm.
