Abstract

Jembatan Raja Haji Fisabilillah memerlukan pemeliharaan terencana untuk menjaga keandalan strukturnya. Namun, unit gondola inspeksi vertikal eksisting setinggi 150 meter saat ini tidak layak operasi untuk memuat manusia karena korosi pada struktur dan sistem penggerak roda gigi rantai. Akibatnya, petugas harus menggunakan tangga vertikal manual monkey ladder yang berisiko tinggi. Penelitian ini bertujuan merancang ulang redesign sistem platform gondola permanen yang aman menggunakan pendekatan kuantitatif berbasis simulasi Metode Elemen Hingga (FEM) dengan material baja struktural ST 37 (EN S235JR). Hasil simulasi statis menunjukkan bahwa Variasi Hollow 50x50 merupakan konfigurasi terbaik, menghasilkan tegangan Von Mises maksimum sebesar 38,852 MPa di sekitar engsel pintu dan deformasi maksimum sebesar 0,36 mm di tengah lantai platform. Nilai tersebut aman di bawah batas luluh material 235 MPa dan defleksi kritis 1 mm, serta menghasilkan Safety Factor minimum sebesar 6,0485. Kebutuhan mekanis sistem penunjang divalidasi menggunakan tali baja dengan koefisien Zp 12, panjang tali 170 meter, diameter drum penggulung 240 mm, dan daya motor sebesar 2,116 kW (2,83 HP). Untuk implementasi, spesifikasi produk dari TMA Winches tipe EL-4 dan Blocstop dari Tractel direkomendasikan karena sistem pelumasan tertutupnya andal terhadap korosi lingkungan laut.

The Raja Haji Fisabilillah Bridge requires planned maintenance to ensure structural reliability. However, the existing 150 meter vertical inspection gondola is currently unfit for human operation due to corrosion in the structure and chain gear drive system. As a result, personnel must rely on manual monkey ladders, which pose high safety risks. This study aims to redesign a permanent gondola platform system that is safe, using a quantitative approach based on Finite Element Method (FEM) simulation with structural steel ST 37 (EN S235JR). Static simulation results indicate that the 50×50 hollow variation is the optimal configuration, producing a maximum Von Mises stress of 38.852 MPa around the door hinge and a maximum deformation of 0.36 mm at the platform center. These values remain below the material yield strength of 235 MPa and the critical deflection limit of 1 mm, yielding a minimum safety factor of 6.0485. Mechanical requirements of the support system are validated using steel wire rope with a Zp coefficient of 12, rope length of 170 meters, drum diameter of 240 mm, and motor power of 2.116 kW (2.83 HP). For implementation, product specifications from TMA Winches type EL 4 and Blocstop by Tractel are recommended, as their sealed lubrication system provides reliable resistance against marine corrosion.
