Abstract
Laut diindonesia merupakan salah satu tempat yang strategis didalam pemanfaatan energi terbarukan seperti pembangkit listrik tenaga arus laut (PLTAL), dimana arus laut yang dimiliki rata-rata sebesar 1-2 m/s. Perencanaan suatu struktur platform berjenis cylindrical meliputi bagian platform, lengan platform dan turbin dengan mempertimbangkan beban-beban yang terjadi pada struktur. Kekuatan dari suatu struktur perlu diketahui agar perencanaan sesuai dengan standart yang telah ditentukan. Pada tugas akhir penulis membahas mengenai kekuatan lengan platform yang berada distruktur platform pada PLTAL. Gaya-gaya dari beban lingkungan menjadi salah satu faktor yang digunakan untuk mengetahui kekuatan dari lengan platform tersebut. Analisis kekuatan lengan platfrom mengunakan finite element analysis sebagai analisa kekuatan yang terjadi pada lengan platform dengan dilakukan 4 variasi kecepatan yakni sebesar 2 m/s, 3 m/s, 4 m/s, 5 m/s. Dari hasil penelitian menunjukan bahwa besar tegangan von misses (σ) pada lengan platform pada kecepatan 2 m/s sebesar 4,3980 x 105 pascal, pada kecepatan 3 m/s sebesar 5,2726 x 105 pascal, pada kecepatan 4 m/s sebesar 6,2941 x 105 pascal, pada kecepatan 5 m/s sebesar 7,6349 x 105 pascal. Mengacu pada ABS “Floating Production Instalation” Part 5A Chapter 1 Section 4 tingkat keamanan dari material semua komponen dapat kategorikan aman karna memiliki nilai σ ≤ 2,06318 x 107 pascal yang dimana lebih kecil 70 % dari kekuatan material yakni jenis material AISI 1202.

Indonesian sea is one of the strategic places in the use of renewable energy such as sea current power plants (PLTAL), where the sea current owned are on average 1-2 m / s. Planning a cylindrical platform structure includes platform parts, platform arms and turbines taking into account the loads that occur in the structure. The strength of a structure needs to be known so that planning in accordance with the standards that have been determined. In the final assignment the author discusses the strength of the platform arm located on the platform structure of PLTAL. Forces of environmental loads are one of the factors used to determine the strength of the platform's arms. Arm strength analysis using the finite element analysis as a strength analysis that occurs on the platform arm with 4 variations of speed, which is 2 m/s, 3 m s, 4 m/s 5 m/s. From the results of the study show that the von misses voltage (σ) on the platform arm at a speed of 2 m/s is 4,3980 x 105 pascal, at a speed of 3 m/s at 5,2726 x 105 pascal, at speed 4 m/s at 6,2941 x 105 pascal, at a speed of 5 m/s at 7,6349 x 105 pascal. Referring to the ABS "Floating Production Instalation" Part 5A Chapter 1 Section 4 the level of safety of the material of all components can be categorized as safe because it has a value of σ ≤ 2,06318 x 107 pascals which is 70% smaller than the strength of the material namely the material type AISI 1202.
