Abstract

Desain wahana apung yang tepat menjadi penting untuk buoyweather type II agar dapat memenuhi kriteria seakeeping saat dioperasikan di laut lepas. Oleh sebab itu pada tugas akhir ini dilakukan optimalisasi desain dimensi wahana apung buoyweather menggunakan metode particle swarm optimization (PSO) dengan diameter dan ketinggian silinder buoyweather sebagai varibel desain. Optimalisasi desain dimensi wahana apung tersebut bertujuan agar memenuhi kriteria kestabilan sampai sea state 6 serta dengan desain dimensi wahana apung yang tepat buoyweather dapat diproduksi secara masasl untuk kepentingan masyarakat. Optimalisasi tersebut mempunyai fungsi tujuan memaksimalkan respon gerak (RAO) heave wahana apung dengan meminimalkan massa wahana apung tersebut. Pengujian dilakukan pada arah gelombang 0o dan pada arah gerak heave serta dengan 3 variasi pembebanan yaitu keadaan kosong, pembebanan 50 dan pembebanan 100. Hasil optimasi didapatkan respon gerak heave maksimum sebesar 3,942 m/m dengan rincian dimensi wahana apung yaitu 1.27 m (D1), 0.91 m (D2), 0.25 m (L1), 0.2 m (L2). Dari hasil optimasi dilakukan perhitungan respon spektrum untuk mengetahui kualitas gerak dari desain dimensi buoyweather dan didapatkan hasil puncak respon spektrum sebesar 7,44 m2/(rad/s). ================================================================= Best design of buoy become important for Buoyweather Type II to be able to achieve seakeeping criteria when operated on the high seas. Therefore, in this final project will be optimized buoyweather buoy dimensional design using particle swarm optimization (PSO) method with diameter and height of cylinder buoyweather as design variable. Optimizing the disgn of the floating vechicle is aimed to achieve the criteria of stability up to sea state 6 and with the appropriate dimensional design buoyweather buoyancy dimensions can be mass produced for the benefit of society. The optimization has the objective function of maximizing the heave wave motion response (RAO) by minimizing the mass of the floating vechicle. The design will be tested on the direction of zero degrees waves as weell as with 3 variations of loading that is empty, 50 load and 100 load. The optimum result obtained a maximum heave motion response of 3,492 m/m with details of floating vechicle dimensions of 1.27 m (D1), 0.91 m (D2), 0.25 m (L1), 0.2 m (L2). From the optimization results calculation of spectrum response to determine the quality of motion of the buoyweather dimension design optimization results and obtained peak response spectrum result of 7.44 m2/(rad/s).
