Inclusive access to water is very important for the tourism sector to maintain a good reputation among tourists and the social license of the local community to operate. While all stakeholders or stakeholders expect the success of tourism which contributes to economic improvement, community welfare, human resource development, and improvement of public health and the environment, tourism activities on Kayangan Island need clean water for their development. Considering that the island is one of the favourite tourist destinations and is growing quite rapidly at this time, there is no effective source of clean water available on the island. Therefore, it can be attempted to provide clean water by using subsea pipes sourced from PDAM Makassar. According to observations from various aspects, the pipe will cross the ocean with a span of ±1500 meters by flowing water with a discharge of 10 lt/s using HDPE pipes with a diameter of 140mm PE100, PN 16 according to SNI standards. For a fairly good security system, the jet pump and the pipe will be tied to a 110 mm diameter stainless steel sling bridge. In addition, at every 6 meters distance, the pipe bridge slings are fitted with ballast loads with hanging slings. In this study, the installation of subsea pipelines requires a variety of supporting equipment and also a complicated implementation, but it is can be carried out considering this needs to be done to support the need for clean water on Kayangan Island to support tourism development.

Marine-based industrial development includes several sectors including Sea Transportation Services, Ferry Services, Capture Fisheries, Offshore Oil & Gas, Marine Biological Resources, Marine Tourism, and Energy Conversion, which in general both management and operations require supporting facilities, namely ships. with certain types that can serve these interests. During the current economic recovery period, there need to be concrete and more innovative steps that must be pursued by all parties, both government and private, in order to reduce the time needed to improve the state’s economic condition. Hence, the role of marine potential is very vital to be further developed in the future. The optimization results of the comparison ship obtained the main dimensions of the design vessel, namely: Lbp = 81.19 m, B = 15.00 m, T = 5.50 m, H = 7.00 m, Cb = 0.75, Cm = 0.99, Cw = 0.84 Cpv = 0.89, Cph = 0.76, Fb = 1.50 m, Fn = 0.22, Displacement = 5280.91 tons, Volume = 5131.583 m3, GRT = 3910 tons, Vs = 12 knots, Lwl = 83.22 m. This comparator ship method makes it easy for ship designers with accurate results.

Main engine dalam pengoperasiannya memerlukan pembakaran secara sempurna untuk mendapatkan mesin yang efektif, salah satunya adalah dengan menggunakan mekanisme injector. Pembakaran yang tidak sempurna dapat mengakibatkan mesin tidak dapat bekerja dengan maksimal, bahkan akan menimbulkan kerusakan mesin sehingga membutuhkan biaya perbaikan dan penggantian spare part-nya. Injector memiliki carakerja dengan memberikan bahan bakar bertekanan tinggi dari injection pump. Fungsi utama injektor diesel adalah alat untuk mengabutkan bahan bakar hingga terpecahpecah menjadi bagian yang halus (kabut) dalam suhu tinggi. Suhu tinggi tersebut akan memberikan dampak pada mesin sehingga perlu diadakan perawatan berkala pada injektor mesin. Penelitian ini menggunakan metode pengumpulan data yang dilakukan dengan riset pustaka dan studi dokumen. Penelitian ini meliputi: mencari data mesin induk (injektor), menganalisa dan mengidentifikasi kerusakan injektor, perbaikan dan pengetesan injektor mesin.

Artificial Intelligence has experienced significant improvements, including its use in sustainable maritime security. This journal discusses the development of information systems that are interconnected and real time providing reports to all parties who need information. Overall, we find that the potential for oil sabotage is always present in the delivery of tankers from FPSO to shuttle tankers. The concept of integrated FPSO offloading management to tankers implies minimizing the potential loss of cargo. At the same time, the intelligent technology most often used to control maritime security is the Automatic Integrated System.

Tangki merupakan wadah penyimpanan muatan dan menjadi bagian utama kapal pengangkut cairan dan gas agar muatan terjaga dan aman. Sebagai media penyimpanan, tangki akan selalu mendapatkan beban yang berasal dari dalam maupun beban yang berasal dari luar tangki. Sloshing merupakan salah satu beban yang berasal dari dalam, sloshing timbul akibat adanya gerakan kapal/tangki mengakibatkan gerak bebas fluida berosilasi menghantam dinding tangki. Tujuan penelitian ini adalah mencari pengaruh muatan terhadap gerakan dan beban sloshing pada tangki dengan variasi jumlah muat. Model tangki yang digunakan mengambil referensi kapal tanker general purpose yang mengangkut minyak mentah dalam kondisi dua dimensi persegi panjang (midship) dengan lebar 8,6 m dan tinggi 8 m dua sisi kiri dan kanan. Variasi yang digunakan adalah volume muat 10% (ketinggian 0,8 m), volume 30% (ketinggian 2,4 m), volume 50% (ketinggian 4 m), variasi 70% (ketinggian 5,6 m) dan variasi 90% (ketinggian 7,8 m). Simulasi dilaksanakan dengan metode numerik yaitu Computational Fluid Dynamic (CFD) menggunakan software Ansys Fluent. Gerakang tangki didasarkan dari gerakan kapal yang dalam hal ini dibatasi pada gerak heaving dan rolling, dari hasil simulasi disimpulkan bahwa efek sloshing terbesar terjadi pada variasi volume muat 10% frekuensi 2,145, sedangkan tekanan terbesar terjadi pada titik sudut kiri bawah tangki dengan tekanan 443,29 Kpa.
