Abstract

Dalam desain struktur kapal, sekat memanjang berperan penting sebagai elemen pendukung kekakuan memanjang kapal terhadap pembebanan global, salah satunya momen lentur akibat kondisi hogging dan sagging. Pemilihan konfigurasi pelat dan penegar yang tepat dapat meningkatkan kekuatan dan efisiensi struktur. Pada penelitian ini dilakukan analisis numerik untuk mengevaluasi pengaruh variasi tebal pelat dan dimensi penegar terhadap respon strukturan sekat memanjang yang bertujuan untuk memperoleh desain optimum berdasarkan kriteria teknis. Simulasi dilakukan menggunakan perangkat lunak ABAQUS CAE dengan meggunakan pendekatan beban berupa rotasi pada reference point untuk merepresentasikan momen lentur. Hal ini dilakukan untuk sembilan variasi model yang masing – masing kriteria evaluasi dibandingkan dengan batas izin. Hasil analisis menunjukkan bahwa peningkatan dimensi pelat dan penegar menurunkan tegangan dan deformasi, namun berbanding terbalik dengan berat struktur dan momen reaksi. Model yang dipilih sebagai desain optimum memiliki performa struktural yang aman, berat paling ringan dengan momen reaksi yang mendekati model dasar. Selain itu, perancangan antarmuka grafis (GUI) menggunakan Macro Manager dan RSG Dialog Builder untuk mengotomatisasi proses pembuatan model yang terbukti efektif dalam konsistensi pemodelan.

In ship structure design, longitudinal bulkheads play an important role as elements supporting the ship's longitudinal stiffness against global loading, one of which is the bending moment due to hogging and sagging conditions. The selection of the appropriate plate and stiffener configuration can enhance the strength and efficiency of the structure. In this study, a numerical analysis was conducted to evaluate the influence of variations in plate thickness and stiffener dimensions on the structural response of longitudinal partitions, aiming to obtain an optimum design based on technical criteria. The simulation was conducted using the ABAQUS CAE software with a load approach in the form of rotation at the reference point to represent the bending moment. This was done for nine model variations, each evaluated against the permissible limits. The analysis results show that increasing the dimensions of the plate and stiffener reduces stress and deformation but is inversely proportional to the weight of the structure and the reaction moment. The model chosen as the optimum design has safe structural performance, the lightest weight, and a reaction moment close to the baseline model. Additionally, the design of the graphical user interface (GUI) using Macro Manager and RSG Dialog Builder to automate the model creation process has proven effective in modeling consistency.
