Abstract

Perairan Arafura memiliki kawasan laut dalam yang memiliki potensi sumber daya kelautan besar, baik dari sektor keanekaragaman hayati, perikanan, migas, maupun mineral laut. Namun, eksplorasi di wilayah ini masih sangat terbatas karena tantangan teknis, terutama di kedalaman ekstrem dan keterbatasan teknologi kendaraan bawah laut dalam negeri. Penelitian ini bertujuan untuk mendesain Deep-Submergence Vehicle (DSV) yang mampu beroperasi hingga kedalaman 3680 meter di Perairan Arafura sebagai sarana riset laut dalam. Tahapan desain dimulai dari penentuan operational scheme di sekitar Cekungan Arafura. Kemudian, jenis dan spesifikasi alat DSV disesuaikan dengan risetnya yang dijalanakan, seperti kamera HD bawah air dan manipulator untuk dokumentasi dan pengambilan sampel biota laut, gravimeter untuk studi cadangan migas, SONAR multibeam untuk pemetaan dasar laut, dan sensor CTD untuk riset kualitas air. payload yang terdiri dari tiga orang, yaitu satu operator dan dua peneliti, serta alat penunjang riset. Langkah selanjutnya adalah menentukan dimensi utama DSV dan didapatkan ukuran Panjang (L) = 9 meter; Lebar (B) = 2,7 meter; dan Tinggi (H) = 4,1 meter. Setelah itu, dilakukan analisis teknis terhadap sistem utama kapal, dilanjutkan dengan pembuatan Lines Plan, General Arrangement, dan model 3D menggunakan perangkat lunak CAD. Estimasi biaya pembangunan DSV yaitu Rp70,027,557,268.30 dan estimasi biaya operasional per tahunnya sebesar Rp1,561,630,028. Struktur pressure hull dirancang berbentuk bola dengan diameter dalam 2 meter dan ketebalan 50 mm, menggunakan material titanium alloy ASTM B265 Grade 5 untuk menjamin kekuatan terhadap tekanan Perairan Arafura di kedalaman 3680 m. Hasil desain ini diharapkan menjadi dasar awal pengembangan teknologi kendaraan laut dalam nasional yang efisien dan berkelanjutan.

The Arafura Sea has deep sea areas with great marine resource potential, both in terms of biodiversity, fisheries, oil and gas, and marine minerals. However, exploration in this region is still very limited due to technical challenges, especially at extreme depths and the limitations of domestic deep-sea vehicle technology. This study aims to design a Deep-Submergence Vehicle (DSV) capable of operating at depths of up to 3,680 meters in the Arafura Sea as a tool for deep-sea research. The design process begins with determining the operational scheme around the Arafura Basin. Then, the type and specifications of the DSV equipment are chosen to the research being conducted, such as underwater HD cameras and manipulators for documenting and collecting marine life samples, gravimeters for oil and gas reserve studies, multibeam SONAR for seabed mapping, and CTD sensors for water quality research. The payload consists of three people, one operator and two researchers, as well as research support equipment. The next step is to determine the main dimensions of the DSV, resulting in the following measurements: Length (L) = 9 meters; Width (B) = 2.7 meters; and Height (H) = 4.1 meters. Following this, a technical analysis of the vessel's main systems was conducted, followed by the creation of a Lines Plan, General Arrangement, and 3D model using CAD software. The estimated construction cost of the DSV is Rp70,027,557,268.30 and the estimated annual operational cost is Rp1,561,630,028. The pressure hull structure is designed in a spherical shape with an inner diameter of 2 meters and a thickness of 50 mm, using titanium alloy ASTM B265 Grade 5 material to ensure strength against the pressure of the Arafura Sea at a depth of 3,680 meters. This design is expected to serve as the initial foundation for the development of efficient and sustainable national deep-sea vehicle technology.
