Abstract

Kapal trimaran merupakan pengembangan desain lambung kapal. Desain 3 buah lambung ini menguntungkan dari sisi berkurangnya nilai resistance, meningkatkan straight line stability dan lain-lain. Akan tetapi kemampuan maneuver trimaran lebih rendah jika dibandingkan dengan kapal monohull. Pada penelitian ini, kapal trimaran didesain menggunakan perbedaan putaran motor di sisi outtriggers hull-nya. Perbedaan putaran antara kedua motor ini mengakibatkan salah satu bagian buritan sisi outrigger memiliki trust yang lebih besar dan menimbulkan gerak yawing pada body kapal trimaran. Untuk mengetes kemampuan maneuver trimaran digunakan standard IMO ITTC 2002 mengenai “turning ability”. Jika belum memenuhi standard maneuverability, maka sistem kembali menggunakan rudder sebagai komponen maneuver-nya. Data performa maneuver nantinya digunakan sebagai data input dan ouput target yang dimasukkan ke program neural network. Neural network ini berfungsi untuk membuat jaringan dan menentukan korelasi antara data input dan output. Neural network memiliki sifat adaptif learning, yakni berulang kali mempelajari data yang diberikan hingga menemukan target nilai error seminim mungkin. ================================================================================================= The trimaran is one of the inventions of the hull design. The multihull design has benefits to reduce resistance, increases straight line stability and others. However, the trimaran has lower maneuverability compared to the monohull ship. In this paper, the trimaran maneuver system is designed using the different RPM between two Brushless DC motor at outtrigger hulls. The difference causes one of the stern parts of the outriggers having higher trust than other and causes yawing motion on the trimaran body. the IMO ITTC 2002 standard was used regarding the "turning ability" to test the maneuverability of the trimaran. Maneuver performance data such as, drift angle, rudder angle, etc will be used as an input and target output data. Then, those data are used for neural network program to create a network and determine the correlation between input and output data. Neural network has the merits in adaptive learning, it can repeatedly learn the data provided to find the minimum error value targeted during creating the network.
