Abstract
Teknologi kelautan berkembang sangat pesat dalam upaya
mengekplorasi dan mengekploitasi sumber daya alam yang ada di
laut terutama minyak bumi dan gas, sehingga banyak bangunan
apung di laut untuk keperluan tersebut seperti semi-submersible
rig. Kondisi lingkungan laut yang begitu ekstrem membuat semisubmersible rig harus handal dan kuat untuk menghadapi semua
gangguan yang ada, salah satunya adalah dengan adanya kontrol
stabilisasi pada semi-submersible rig agar dapat tetap kuat pada
posisi yang telah ditentukan letaknya.Tujuan dari penelitian ini
adalah untuk mendesain sistem kontrol stabilisasi pada platform
semi-submersible menggunakan metode kontrol optimal Linier
Quadratic Gaussian (LQG). Kontrol LQG memiliki sifat yang
robust terhadap disturbance pada frekuensi rendah dan tinggi.
Berdasarkan Hasil performasi sistem kendali LQG secara
keseluruhan, sistem mampu mengendalikan gangguan berupa
variasi gelombang frekuensi rendah dan tinggi dan gangguan
gelombang sudut 30 pada seastate 6. Berdasarkan hasil simulasi,
didapatkan penyimpangan maksimal sebesar 1.161 m untuk arah
sway dan yaw sebesar 0.0256 radian hal ini masih diperbolehkan.
Sedangkan kondisi dengan gangguan gelombang diperoleh bahwa
sistem kontrol dapat mengikuti gangguan dengan sangat baik.

Marine technology is growing very rapidly in an effort to
explore and exploit the natural resources of the sea, especially oil
and gas, so many buildings floating in the ocean for such
purposes such as semi-submersible rig. Conditions are so extreme
marine environments make the semi-submersible rig to be
reliable and robust to deal with all the existing problems, one of
which is the presence of stabilization control on a semisubmersible rig in order to remain strong at a predetermined
position. The Purpose of this research is to design the control
system stabilization in the semi-submersible platform using
Linear quadratic optimal control method Gaussian (LQG). LQG
control has robust nature of the disturbance at low and high
frequencies. Based on the results performance LQG control
system as a whole, the system is able to control the disturbances
in the form of variations of low and high frequency waves and
wave disturbance at an angle of 30 sea state 6. Based on
simulation results, obtained a maximum deviation of 1.161 m for
sway and yaw is 0.0256 radians it is still allowed. While the
condition of the obtained wave disturbances that can follow
interference control system very well.
