Abstract
Marine Semi-Submersible platform merupakan bangunan lepas pantai diatas permukaan air yang secara umum digunakan untuk penambangan offshore, basecamp keamanan kapal, dan tempat produksi minyak di lepas pantai. Bangunan ini ditujukan untuk tetap stabil terhadap posisinya semula dengan cara dipancang kebawah laut dengan beberapa jangkar dan struktur penahan. Biaya dan struktur untuk mempertahankan posisi ini sangat besar. Digunakan sistem penggerak pada setiap sudut platform berjumlah empat buah sehingga platform mampu beradaptasi untuk kembali ke posisi semula dengan meminimalisir pengunaan jangkar dan dapat diposisikan dalam kedalaman laut berapapun. Dynamic Positioning System (DPS), yaitu Sebuah sistem yang mampu untuk mempertahankan posisi akan digunakan pada prototipe Marine Semi-submersible platform yang dikembangkan pada tugas akhir ini. Dimana sistem DPS ini direalisasi menggunakan metoda Differential GPS, dimana perubahan posisi (Δx dan Δy) dan arah hadap (Δθ) platform diketahui melalui GPS dan kompas. Dari perubahan nilai Δx, Δy dan Δθ platform, akan ditentukan reaksi tindakan untuk menyesuaikan kembali posisi. Karena adanya error pada nilai GPS yang cukup besar saat penerimaan sinyal informasi koordinat dari satelit, maka untuk mengoreksi error tersebut digunakan metoda D-GPS dimana posisi GPS platform mendapat koreksi dari pangkalan yang ada di darat atau kapal lain dengan mengirimkan sinyal berisi informasi tentang posisinya. Sistem D-GPS yang dikembangakan pada penelitian ini, mampu mengurangi error GPS pada platform sebesar 31,22% dalam 11 percobaan dimana uji coba dilakukan di danau 8 ITS.

Marine Semi-Submersible platform is an offshore building above the water surface that is commonly used for offshore mining, ship security basecamp, and oil production sites offshore. The building is intended to remain stable against its original position by being put under the sea with several anchors and retaining structures. The costs and structure for maintaining this position are very expensive. In solving the problem, a drive system is used in each corner of the building, amounting to four so that the platform is able to adapt to return to its original position so as to minimize the use of anchors and can be positioned in any depth of the sea. Dynamic Positioning System (DPS), which is a system that is able to maintain the position will be used on the Marine Semi-submersible platform prototype developed in this final project. Where the DPS system is realized using the Differential GPS method, where changes in position (Δx and Δy) and direction (Δθ) of the platform are known through GPS and compass. From the changes in the values Δx, Δy and Δθ platform, the action reaction will be determined to readjust the position. Due to a large GPS value error when receiving a coordinate information signal from a satellite, the D-GPS method is used to correct the error where the GPS platform position is corrected from the base on land or other vessels by sending a signal containing information about its position. The D-GPS system developed in this study was able to maintain the position of the prototype platform while reducing the error of GPS by 31.22 % based on 11 times of trials, where trials were carried out on lake 8 ITS.
