Abstract

PT. Terminal Petikemas Surabaya (TPS) adalah salah satu anak perusahaan yang tergabung dalam Pelindo III Group dan bergerak di bidang jasa kepelabuhanan, khususnya terminal petikemas ekspor-impor dan domestik. Untuk mencapai target operasional, terminal petikemas memiliki sejumlah fasilitas, terutama fasilitas untuk memenuhi standar kedalaman kolam dermaga yang dibangun pada jarak sekitar 1.500 meter dari lapangan penumpukan. Untuk mencapai dermaga tersebut, tersedia fasilitas berupa trestle, yaitu akses jembatan bagi truk petikemas untuk mengambil dan mengangkut petikemas dari kapal yang bertambat di dermaga menuju lapangan penumpukan maupun sebaliknya. Peran trestle sangat penting sebagai jalur lalu lintas truk petikemas yang keluar masuk dermaga. Trestle ini memiliki panjang sekitar 1.500 meter, lebar 14,04 meter, serta dua lajur lalu lintas dengan lebar total 11 meter. Setelah beroperasi sejak awal tahun 1990-an, trestle mulai mengalami indikasi kerusakan berupa retak pada pelat, retak vertikal pada bagian tengah bentang balok trestle, serta kerusakan pada elastomer bearing pad. Pada tugas akhir ini dilakukan evaluasi struktur bangunan atas trestle akibat beban yang terjadi di lapangan serta evaluasi bangunan bawah akibat beban gempa. Selain itu dilakukan perbaikan dan perkuatan melalui penggantian elastomer bearing pad, perkuatan balok menggunakan CFRP, serta perkuatan pondasi pipa baja akibat beban gempa menggunakan bracing pipe. Tahapan penelitian dimulai dengan pengumpulan data eksisting dan survei lapangan untuk mengetahui kondisi aktual trestle. Setelah kerusakan diidentifikasi, dilakukan pemodelan struktur dengan pembebanan jembatan, kemudian dibandingkan kapasitas elemen struktur terhadap gaya-gaya dalam hasil analisis struktur. Selanjutnya dilakukan perhitungan kebutuhan perkuatan CFRP dan bracing pipe serta penyusunan metode pelaksanaan pemasangan CFRP dan penggantian elastomer bearing pad. Harapan dari tugas akhir ini adalah memperpanjang umur layanan trestle melalui penggantian elastomer bearing pad, memperkuat balok menggunakan CFRP, memperkuat pondasi pipa baja menggunakan bracing, serta menghasilkan metode pelaksanaan pemasangan CFRP dan penggantian elastomer bearing pad pada trestle tersebut.

PT. Surabaya Container Terminal (TPS) is one of the subsidiaries of the Pelindo III Group and operates in port services, particularly export-import and domestic container terminal operations. To support its operational targets, the container terminal is equipped with several facilities, including a trestle built approximately 1,500 meters from the container yard to meet the required berth basin depth standards. The trestle serves as a bridge access for container trucks transporting containers between berthed container ships and the container yard. This facility plays a vital role in supporting the movement of container trucks entering and leaving the berth. The trestle is approximately 1,500 meters long, 14.04 meters wide, and consists of two traffic lanes with a total width of 11 meters. After operating since the early 1990s, the trestle has shown signs of deterioration, including cracks in the deck slab, vertical cracks at the mid-span of the trestle beams, and damage to the elastomeric bearing pads. In this final project, the trestle superstructure is evaluated for field loading, while the substructure is evaluated for earthquake loading. Repair and strengthening measures include replacing the elastomeric bearing pads, strengthening the beams using CFRP, and strengthening the steel pipe foundation against seismic loads using bracing pipes. The study begins with collecting existing data and conducting field surveys to identify the actual condition of the trestle. After identifying the damage, the structure is modeled under bridge loading conditions, followed by a comparison between the structural element capacities and the internal forces obtained from the structural analysis. The required CFRP and bracing pipe reinforcement are then calculated, and construction methods for CFRP installation and elastomeric bearing pad replacement are prepared. This final project aims to extend the service life of the trestle through elastomeric bearing pad replacement, beam strengthening using CFRP, steel pipe foundation strengthening using bracing, and the development of practical construction methods for CFRP installation and elastomeric bearing pad replacement.
