Abstract

Perkembangan teknologi komputasi dalam bidang rekayasa mendorong kebutuhan akan proses analisis yang cepat, efisien, dan ramah pengguna. Salah satu pendekatan yang digunakan adalah integrasi metode elemen hingga (Finite Element Method/FEM) dengan Graphical User Interface (GUI), yang mempermudah pengguna dalam melakukan pemodelan, analisis, hingga simulasi tanpa perlu menggunakan skrip secara langsung. Pada penelitian ini, dirancang GUI berbasis plug-ins Abaqus CAE dengan bahasa Python yang dapat mengotomatisasi proses pemodelan struktur. Penerapan fokus diberikan pada analisis kekuatan struktur car deck kapal Ro-Ro, khususnya menggunakan material sandwich panel tipe rectangular o-core yang menawarkan bobot ringan dan kekakuan tinggi. Sandwich panel dipilih sebagai alternatif material struktur konvensional guna meningkatkan efisiensi dan menurunkan berat total kapal. Pada penelitian ini, rectangular o-core sandwich panel dibuat menjadi 4 model yang divariasikan pada setiap model berupa ketebalan core, ketebalan face dan bottom plate, serta lebar dan jarak core. Dari hasil percobaan yang telah dilakukan, didapatkan desain geladak dengan rectangular o-core sandwich panel yang paling optimal dengan tinggi core 60 mm, lebar core 120 mm, jarak core 120 mm, tebal face dan bottom plate 2 mm, serta tebal core 5 mm. Hasil tegangan akibat beban lateral yaitu 28,32 MPa, tegangan akibat beban kompresi 87,72 MPa, deformasi 2,347 mm, dan berat struktur sebesar 25,05 Ton. Nilai tegangan yang terjadi jauh lebih kecil dibandingkan nilai tegangan yang diizinkan. Melalui GUI yang dirancang, pengguna juga dapat melakukan pemodelan geometri, input parameter material, pembebanan, hingga pembuatan mesh secara lebih cepat dan terstruktur. Penelitian ini diharapkan dapat mendukung proses analisis kekuatan sandwich panel secara sistematis, akurat, serta efisien dalam konteks desain struktur car deck kapal Ro-Ro.

The advancement of computational technology in engineering has driven the demand for fast, efficient, and user-friendly analysis processes. One approach widely adopted is the integration of the Finite Element Method (FEM) with a Graphical User Interface (GUI), which simplifies modeling, analysis, and simulation tasks without the need for direct scripting. In this study, a GUI is designed using the Abaqus CAE plug-ins with Python scripting to automate the structural modeling process. The focus of application is on the structural strength analysis of a Ro-Ro ship car deck, specifically using rectangular o-core type sandwich panel material, which offers lightweight characteristics and high stiffness. Sandwich panels are selected as an alternative to conventional structural materials to enhance efficiency and reduce overall ship weight. In this study, the rectangular o-core sandwich panel is modeled in four variations, with differences in core thickness, face and bottom plate thickness, as well as core width and spacing. From the analysis results, the most optimal sandwich panel deck design is achieved with a core height of 60 mm, core width of 120 mm, core spacing of 120 mm, face and bottom plate thickness of 2 mm, and core thickness of 5 mm. The resulting stresses are 28.32 MPa due to lateral load and 87.72 MPa due to compressive load, with a deformation of 2.347 mm and a total structural weight of 25.05 tons. These stress values are significantly lower than the allowable stress limits. Through the designed GUI, users can perform geometry modeling, material parameter input, loading, and meshing more quickly and in a structured manner. This study is expected to support the structural strength analysis of sandwich panels in a systematic, accurate, and efficient manner within the context of Ro-Ro ship car deck design.
