Abstract
Kapal ferry Ro-Ro adalah moda transportasi yang paling banyak digunakan untuk menghubungkan pulau-pulau di Indonesia. Di Indonesia intensitas bencana karena faktor alam relatif tinggi, sehingga banyak kapal ferry Ro-Ro yang mengalami kecelakaan. Selain karena faktor alam kecelakaan kapal ini juga terjadi akibat karakteristik kapal yang kurang sesuai untuk kondisi alam daerah tersebut. Oleh sebab itu, penggunaan metode optimasi sangat tepat untuk menyelesaikan persoalan ini dengan menghasilkan desain kapal baru yang memiliki karakteristik teknis yang lebih sesuai dengan kondisi perairan di rute pelayaran tersebut. Salah satu rute pelayaran yang sering terjadi kecelakaan adalah rute Pelabuhan Bajoe – Pelabuhan Kolaka. Metode optimasi yang digunakan adalah global optimization dengan menggunakan artificial neural network. Optimasi dilakukan dengan menggunakan software visual basic dan maxsurf dengan studi kasus kapal ferry (Ro-Ro) rute Pelabuhan Bajoe – Pelabuhan Kolaka. Dari hasil optimisasi yang dilakukan dengan 1-10 nilai train, didapatkan ukuran utama yang memenuhi batasan optimisasi dan ukuran utama yang paling optimum adalah Lpp = 56,258 m, B = 12,88 m H = 4,046 m dan T = 2,592 m dan fungsi objektif yaitu meminimumkan biaya pembangunan kapal dengan nilai $8.523.954,64. Perbandingan estimasi biaya pembangunan kapal existing dan estimasi biaya pembangunan hasil optimasi adalah 10,58% dengan selisih biaya pembangunan sebesar $1.008.473,03. Sehingga hasil optimasi tersebut menghasilkan fungsi objektif yang lebih optimum.
