Abstract

Indonesia merupakan negara maritim dengan wilayah terbesarnya adalah perairan yang artinya penggunaan kapal sangat vital terutama untuk perdagangan, keamanan dan mencari ikan. Tingginya gelombang di laut Indonesia berpotensi membahayakan pelaut yang dapat merugikan dari segi harta maupun jiwa karena jika kapal dapat terbalik saat berlayar ditengah ombak yang tinggi. Dalam keadaan ideal, kapal yang berlayar di laut didesain harus dapat berjalan stabil meski diterjang ombak. Salah satu upaya yang dapat dilakukan untuk menstabilkan kapal dari gelombang laut yang terjadi adalah dengan memberi penambahan Gyrostabilizer. Gyrostabilizer merupakan suatu alat yang berputar ke arah rotasi dan dipasangkan pada sistem utamanya untuk membantu menstabilkan sistem utama tersebut. Gyrostabilizer dapat menjadi solusi bagi kapal – kapal yang berlayar di lautan khususnya Indonesia yang memiliki ombak yang cukup tinggi. Penggunaan gyrostabilizer sangat jarang sekali digunakan di Indonesia.. Tujuan dari penelitian ini adalah untuk mengamati karakteristik gyrostabilizer sebagai alat stabilizer pada perahu boat. Dilakukan pengujian secara simulasi dengan software Matlab Simulink berdasarkan perumusan persamaan matematis dengan Metode Lagrange untuk mendapatkan waktu stabilitas dan input torsi gimbal yang dibutuhkan agar model penelitian dalam keadaan ekuilibrium atau stabil. Sistem Gyrostabilizer disimulasikan menggunakan satu dan dua giroskop. Hasil simulasi menunjukkan bahwa sistem gyrostabilizer dengan dua giroskop dapat menahan torsi berupa disturbance impuls lebih besar dibandingkan dengan sistem yang menggunakan satu giroskop. Sistem dengan dua giroskop dapat menstabilkan distubance paling besar 6Nm sedangkan sistem satu giroskop sebesar 3 Nm. Dengan disturbance yang sama, sistem dengan dua giroskop dapat memberikan respon stabitas yang lebih cepat dibandingkan dengan sistem dengan satu giroskop. Berdasarkan hasil simulasi simulink dan simscape dengan variasi disturbance pada sistem gyrostabilizer, ditunjukkan bahwa semakin besar disturbance maka akan menyebabkan respons yang lebih lama untuk sistem agar dapat kembali ke posisi ekuilibrium dan input torsi gimbal yang lebih besar pula. ================================================================================================ Indonesia is a maritime country with the largest region being waters, which means that the use of ships is vital especially for trade, security and fishing. The high waves in the Indonesian sea have the potential to endanger seafarers which can be detrimental in terms of assets and lives because if the ship can be overturned while sailing amid high waves. In ideal conditions, ships that sail at sea are designed to be able to walk stably despite being hit by waves. One of the efforts that can be done to stabilize the ship from the ocean waves that occur is to add Gyrostabilizer. The Gyrostabilizer is a device that rotates in the direction of rotation and is attached to the main system to help stabilize the main system. Gyrostabilizer can be a solution for ships sailing in the ocean, especially Indonesia which has high waves. The use of gyrostabilizers is very rarely used in Indonesia. The purpose of this study was to observe the characteristics of the gyrostabilizer as a stabilizer on a boat. Simulated simulation using Matlab Simulink software is based on the formulation of mathematical equations with the Lagrange Method to obtain the stability time and dreadlocks torque input needed for the research model to be in equilibrium or stable. Gyrostabilizer systems are simulated using one and two gyroscopes. The simulation results show that the gyrostabilizer system with two gyroscopes can withstand torque in the form of a larger impulse disturbance compared to a system that uses one gyroscope. Systems with two gyroscopes can stabilize distubances at most 6Nm while one gyroscope system is 3 Nm. With the same disturbance, a system with two gyroscopes can provide faster response to stability than a system with a gyroscope. Based on simulink and simscape simulation results with disturbance variations on the gyrostabilizer system, it is shown that the greater the disturbance will cause a longer response for the system to return to the equilibrium position and the larger dreadlocks torque input.
