Abstract

Geladak dan bangunan atas kapal merupakan salah satu bagian yang mempengaruhi berat kapal. Bus air dipilih sebagai model yang digunakan karena kapal ini merupakan jenis kapal yang beroperasi dengan kecepatan tinggi dan membutuhkan berat yang ringan. Penerapan material komposit sendiri diharapkan dapat memenuhi kekuatan dan mengurangi berat apabila dibandingkan dengan pelat aluminium. Analisis yang dilakukan dalam penelitian ini adalah mencari pengaruh perubahan tegangan antara material aluminium dan material komposit serta mencari perbandingan nilai tegangan, deformasi serta berat pada struktur bus air antara material aluminium dan material komposit. Besarnya tegangan yang terjadi pada struktur keseluruhan bus air baik itu dengan material aluminium alloy maupun dengan material aluminium alloy + komposit EN AC-43100 [AlSi10Mg(b) + SiC/15p] keduanya memenuhi tegangan ijin, dimana maksimal tegangan struktur keseluruhan bus air dengan material aluminium alloy yang diperoleh sebesar 43.057 MPa dan nilai tegangan bus air dengan material aluminium alloy + komposit EN AC-43100 [AlSi10Mg(b) + SiC/15p] diperoleh sebesar 37.159 MPa. Sehingga dapat disimpulkan bahwa material komposit EN AC-43100 [AlSi10Mg(b) + SiC/15p] adalah bahan alternatif untuk pembuatan kapal. Pemodelan diterapkan pada geladak dan bangunan atas dengan hasil bahwa pengurangan ketebalan pelat komposit kapal EN AC-43100 [AlSi10Mg(b) + SiC/15p] cukup signifikan untuk mengurangi berat kapal.

The deck and superstructure of the ship are one of the parts that affect the weight of the ship. Water bus was chosen as the model used because this ship is a type of ship that operates at high speed and requires light weight. The application of the composite material itself is expected to fulfill the strength and reduce weight when compared to aluminum plates. The analysis carried out in this study was to look for the effect of changes in stress between aluminum and composite materials and to look for comparisons of stress, deformation and weight values in the water bus structure between aluminum and composite materials. The amount of stress that occurs in the overall structure of the water bus both with aluminum alloy material and with aluminum alloy material + composite EN AC-43100 [AlSi10Mg(b) + SiC/15p] both meet the allowable stress, where the maximum stress in the overall structure of the water bus with the material The obtained aluminum alloy was 43,057 MPa and the water bus stress value with aluminum alloy + EN AC-43100 composite [AlSi10Mg(b) + SiC/15p] material was 37,159 MPa. So it can be concluded that the composite material EN AC-43100 [AlSi10Mg(b) + SiC/15p] is an alternative material for shipbuilding. The modeling was applied to the deck and superstructure with the result that the reduction in the thickness of the ship's composite plate EN AC-43100 [AlSi10Mg(b) + SiC/15p] was significant enough to reduce the ship's weight.
