Abstract

Kapal ferry ro-ro sesuai fungsinya sebagai kapal penyeberangan penumpang dan kendaraan antar pulau memiliki karakteritik yang berbeda dibanding kapal niaga pada umumnya, khususnya pengunaan sistem kemudi ganda dengan rasio jarak antar daun kemudi yang relatip besar, hal ini sangat berdampak terhadap kemampuan olah gerak kapal.Penelitian ini bertujuan untuk menganalisiskemampuan maneuvering kapal ferry melalui pengaturan sudut kemiringan dan jarak antar daun kemudi. Program MATLAB-Simulink digunakan dalam simulasi turning circle dan zig-zag maneuvering. Program simulasi telah dikembangkan dengan konsep time domain simulation berdasarkan persamaan model matematika pergerakan kapal pada 3-DOF (Degres of Freedom) yang meliputi persamaan komponen lambung, propeler dan daun kemudi beserta koefisien hidrodinamaka didalamnya. Hasil penelitian menujukan bahwa seiring dengan bertambahnyasudut kemiringan daun kemudi dapat meningkatkan kemampuan turning circle kapal, namun sebaliknya pada gerak zig-zag maneuvering. Selanjutnya dengan bertambahnya jarak antar daun kemudi dapat meningkatkan kemampuan baik turning circle dan zig-zag maneuvering, namun dengan momen daun kemudi yang relative besar maka hal ini dapat membahayakan kapal.

Abstract

Indonesian shipbuilding Industry plays significant roles in supporting the economics of the country in the utilization of sea resources, the distribution of natural resources as well as interconnecting people between islands. Hence, it is significant for this industry to survive and keep growing and being competitive not only to fulfill the domestic need on ships but also for export to overseas. Support from the Indonesian government with the policy to build all ships which are operated domestically in the Indonesian shipyards is needed. In the global level, the individual shipyard is relatively difficult to compete with the overseas shipyard. This is because the current global competition is not between individual shipyards but between collaboration shipyards. One of the reasons is there is no collaboration model between shipyards which appropriate with the condition of Indonesian shipyards herself can be found in the literature. This paper discusses an integration model for 4 Indonesian BUMN shipyards which is based on the domestic shipyards characteristics and challenges faced in the implementation stages.
