Abstract
Jembatan sebagai penghubung antarwilayah harus direncanakan dengan memperhatikan aspek kekuatan, stabilitas, efisiensi, dan estetika. Jembatan Aik Bari IV yang berlokasi di Kabupaten Sumbawa, Provinsi Nusa Tenggara Barat, memiliki panjang total sekitar 240 meter. Saat ini, jembatan tersebut menggunakan sistem struktur rangka baja dengan beberapa pilar yang berada di tengah alur sungai. Kondisi ini dinilai kurang optimal karena menyebabkan berkurangnya lebar aliran efektif sungai, meningkatkan potensi terjadinya gerusan lokal di sekitar pondasi, serta belum memenuhi aspek estetika secara maksimal. Untuk mengatasi permasalahan tersebut, diusulkan modifikasi menjadi jembatan cable-stayed dengan sistem two-inclined-plane semi-harp. Pada sistem ini, gelagar menerus ditopang oleh kabel-kabel miring yang terhubung ke pylon sebagai elemen penahan utama. Konfigurasi kabel semi-harp dipilih untuk meningkatkan distribusi beban, kekakuan lateral, dan menambah nilai arsitektural, sedangkan gelagar menggunakan steel orthotropic trapezoidal box girder guna mengurangi berat sendiri sekaligus meningkatkan stabilitas aerodinamis terhadap beban angin. Pylon direncanakan dari beton bertulang berbentuk A-frame agar mampu menahan gaya kabel secara optimal sekaligus memperkuat tampilan visual jembatan. Perencanaan dilakukan melalui tahapan studi literatur, preliminary design, perencanaan struktur sekunder, analisis pembebanan, pemodelan dan analisis struktur, desain struktur utama, kontrol stabilitas aerodinamis, analisis staging, perencanaan bangunan bawah, hingga penyusunan gambar rencana. Hasil perencanaan meliputi dimensi pylon, kabel, dek jembatan, angkur, trotoar, railing, struktur bawah, serta metode pelaksanaan. Dengan modifikasi ini, desain Jembatan Aik Bari IV diharapkan mampu menghasilkan struktur yang lebih efisien, aman, dan estetis, sekaligus mendukung peningkatan konektivitas di wilayah Samota, Kabupaten Sumbawa

Bridges as interregional connectors must be designed by considering aspects of strength, stability, efficiency, and aesthetics. The Aik Bari IV Bridge, located in Sumbawa Regency, West Nusa Tenggara Province, has a total length of approximately 240 meters and currently employs a steel truss structural system with several piers positioned within the river channel. This condition is considered less optimal as it reduces the effective flow width of the river, increases the potential for local scour around the foundations, and does not fully satisfy aesthetic requirements. To overcome these issues, a modification to a cable-stayed bridge with a two-inclined-plane semi-harp system is proposed. In this system, the continuous girder is supported by inclined cables connected to the pylon as the primary load-resisting element. The semi-harp cable configuration is selected to improve load distribution, lateral stiffness, and architectural value, while the girder utilizes a steel orthotropic trapezoidal box girder to reduce self-weight and enhance aerodynamic stability under wind loads. The pylon is designed as an A-frame reinforced concrete structure to optimally resist cable forces while strengthening the visual appearance of the bridge. The planning process is conducted through stages including literature review, preliminary design, secondary structure design, load analysis, structural modeling and analysis, main structure design, aerodynamic stability control, staging analysis, substructure design, and preparation of design drawings. The design results include the dimensions of the pylon, cables, bridge deck, anchorage system, sidewalks, railings, substructure components, and construction methodology. With this modification, the Aik Bari IV Bridge design is expected to produce a more efficient, safe, and aesthetically pleasing structure while supporting improved connectivity in the Samota region, Sumbawa Regency.
