Abstract
Stabilitas kapal adalah salah satu kriteria penting untuk keselamatan kapal seperti yang disyaratkan oleh IMO dan Biro Klasifikasi Indonesia (BKI) dalam berbagai aturan. Salah satu aturannya adalah kode IMO Intact Stability. Di antara banyak faktor yang mempengaruhi stabilitas kapal adalah muatan kapal yang dalam aplikasi bervariasi dalam berat dan jenis kendaraan. Penelitian saat ini mengembangkan sistem bongkar muat untuk menganalisis stabilitas kapal dalam variasi kondisi menggunakan feri 500 GT sebagai kapal target. Sistem ini dibuat dalam bentuk paket Excel yang terhubung ke Maxsurf Stability untuk penggunaan yang lebih mudah untuk pengguna. Visual Basic digunakan untuk menulis kode (coding) untuk perintah pada aplikasi. Hasil simulasi mengungkapkan bahwa pada kondisi awal tanpa muatan, kapal memiliki GZ maksimum 1,4 m pada sudut kemiringan sekitar 40o. Setelah itu, kapal perlahan kehilangan momen penguatnya dan mulai terbalik pada sekitar 75o sudut kemiringan. Pada muatan setengah, muatan tiga per empat, dan muatan penuh, kapal memiliki GZ maksimum masing-masing 1,1 m, 1,05 m dan 0,97 m pada sudut tumit yang sama sekitar 30o. Sesuai dengan itu, kapal mulai terbalik setelah mengalami heeling sekitar 76o, 74o dan 73o masing-masing. Pada kondisi kelebihan beban, kapal memiliki GZ maksimum 0,92 m pada sudut tumit sekitar 30o dan mulai terbalik pada sekitar 71o sudut kemiringan. Pada semua kondisi termasuk kelebihan muatan, kapal menampilkan nilai GZ positif dan aman untuk berlayar sebagaimana dibuktikan dengan kecocokannya dengan aturan IMO Intact Stability. Penelitian ini telah berhasil mengembangkan sistem bongkar muat yang mampu menganalisis stabilitas kapal di berbagai kondisi pemuatan.

Ship stability is one of important criteria for ship safety as required by IMO and Indonesia Classification Bureau (BKI) in various rules. One of the rules is the IMO code of Intact Stability. Among many factors affecting the ship stability is the ship load which in the application varies in weight and types of vehicles. In its use, Maxsurf has been used to analyze various conditions of the ship, including stability. However, Maxsurf is too complicated to be used by ordinary people, and training is needed to run the program. For that a package is needed to mediates laymen and Maxsurf for easy analysis. The current research developed a loading and unloading system to analyse the ship stability in such variation of conditions using a 500 GT ferry as the target ship. The system was established in the form of Excel package connected to Maxsurf Stability for a user friendlier application. Visual Basic was employed to write the codes (coding) for the package command. Simulation output revealed that at initial condition of zero loading, the ship has a maximum GZ of 1.4 m at heel angle of about 40o. Afterwards, the ship slowly loses its righting moment and started to capsize at about 75o heel angle. At half loaded, third-quarterly loaded and a fully loaded, the ship possesses maximum GZ of 1.1 m, 1.05 m and 0.97 m respectively at similar heel angle of about 30o. Correspondingly, the ship started to capsize after heeling for about 76o, 74o and 73o respectively. At overload condition, the ship possesses a maximum GZ of 0.92 m at heel angle of about 300 and started to capsize at about 71o heel angle. At all conditions includes overloaded, the ship displays positive GZ values and is safe to sail as evidenced by its compliance to IMO Intact Stability rule. The research has successfully developed the loading and unloading system capable of analysing the ship stability at various loading conditions.
