Abstract

Keselamatan kapal dapat dilihat dari beberapa aspek salah satunya yaitu kekuatan konstruksi termasuk konstruksi kamar mesin. Kamar mesin pada kapal besar biasanya terdapat lebih dari satu lantai seperti geladak dasar, geladak antara, dan geladak utama. Penumpu geladak berperan besar dalam menahan dan menyalurkan berat atau beban yang ada dan bekerja di atas geladak. Penelitian ini bertujuan untuk mendapatkan konfigurasi struktur paling optimum ditinjau berdasarkan besar tegangan dan berat yang paling minimum. Konfigurasi yang digunakan dalam penelitian ini adalah girder tanpa penumpu, girder ditumpu pilar, dan girder ditumpu kantilever. Untuk mendapatkan tegangan dan berat konstruksi dilakukan optimasi dengan metode trial and error dengan batasan dan fungsi objektif berupa berat struktur. Setelah dilakukan analisis didapatkan masing-masing nilai tegangan dari girder tanpa penumpu, girder ditumpu pilar, dan girder ditumpu kantilever adalah 189,580 MPa, 157,854 MPa, dan 212,620 MPa. Berat konstruksi untuk masing-masing konfigurasi girder tanpa penumpu, girder ditumpu pilar, dan girder ditumpu kantilever adalah 168,821 ton, 160,226 ton, dan 166,429 ton. Dikarenakan tegangan pada ketiga konfigurasi telah memenuhi tegangan izin, maka konfigurasi yang optimum adalah girder ditumpu pilar.

Ship safety can be seen from several aspects, one of which is the strength of structure including engine room structure. Engine rooms on large ships usually have more than one floor such as first deck, second deck, and main deck. Deck support plays a major role in holding and distributing the weight or load that exists and works on the deck. This study aims to obtain the most optimum structural configuration based on the minimum stress and weight. The configurations used in this study are girders without supports, girders supported by pillars, and girders supported by cantilevers. To obtain the stress and structural weight, optimization is carried out using the trial and error method with constraints and objective functions in the form of structural weight. After the analysis, the stress values of girder without support, girder supported by pillar, and girder supported by cantilever are 189,580 MPa, 157,854 MPa, and 212,620 MPa, respectively. The structural weight for each configuration of girder without support, girder supported by pillars, and girder supported by cantilever is 168,821 tons, 160,226 tons, and 166,429 tons. Since the stresses in the three configurations have met the permit stresses, the determination of the optimum configuration is based on the construction weight. Therefore the most optimum configuration is girders supported by pillars.
