Abstract

Kapal perang korvet kelas SIGMA adalah kapal perang patrol dengan kemampuan mengarungi lautan. Korvet kelas SIGMA (Ship Integrated Geometrical Modularity Approach) dirangcang untuk TNI Angkatan Laut oleh Damen Schelde Naval Shipbuilding. Fungsi dari kapal tersebut yaitu untuk berlayar mengitari daerah zona ekslusif ekonomi maupun untuk tugas kenegaraan. Karena hal tersebut, maka diperlukannya kenyamanan pada penumpang. Seakeeping atau perilaku bangunan apung diatas gelombang akan mempengaruhi kenyamanan terhadap penumpang. Oleh karenanya dirancang kendali logika fuzzy untuk pengendalian seakeeping pada kapal SIGMA. Hasil yang didapatkan dari penelitian ini bahwa untuk respon uji kendali rolling dan heaving pada saat open loop menghasilkan error steady state sebesar 2,2% dan 9%. Untuk uji close loop saat keadaan tanpa gangguan gelombang menghasilkan nilai rolling dan heaving menghasilkan nilai error steady sebesar 1,1% dan 4,5%. Ketika diberikan gangguan gelombang saat keadaan close loop menghasilkan nilai maksimum overshoot untuk heaving dan rolling sebesar 6.8x10-3 radian dan 1,5 meter. Saat mendapatkan gangguan angin pada sudut 100, 1000, dan 1700 menghasilkan nilai maksimum overshoot pada keadaan rolling dan heaving sebesar 0.45, -0,4 dan -0,08 rad dan 9,8, -8,2 dan -3,2 m. Nilai frekuensi terbesar pada kurva RAO yaitu saat keadaan ketika diberikan gangguan gelombang dan angin saat sudut 1000. ======================================================================================================== Warship corvette SIGMA is a class of war vessels patrol with the ability to travel over sea.Corvette class sigma (ship integrated geometrical modularity approach ) designed to the navy by damen schelde naval shipbuilding. Function of a ship are to sail around the region exclusive economic zone and to the task of statehood.Because those things, then required on passenger. seakeeping comfort or behavior of a building above the waves driftwood would affect the comfort for the passengers.Therefore designed fuzzy logic to control seakeeping on a ship sigma. The results obtained from this research that a test for response control of rolling and heaving at the time of the open loop produces steady state error of 2.2% and 9%. To test the close loop when circumstances without interruption waves rolling and heaving produces steady state error of 1.1% and 4.5%. When given wave of disruption close loop generate maximum value to overshoot heaving and rolling of 6.8 x 10-3 radian and 1.5 meters. While getting the wind disturbance at an angle of 100, 1000 and 1700 produce the maximum value overshoot on the circumstances of rolling and heaving at 0.45, -0,4 and -0,08 rad and 9.8, -8,2 and -3,2 m. the value of the frequency of the largest on a curve RAO and this is as when given a state of disorder tide and wind when the angle of 1000.
