Abstract

Sebagai suatu kapal patroli, offshore patrol vessel (OPV) 80 m memiliki mode operasi yang beraneka ragam: kondisi pengintaian (10 knot), kondisi patroli (18 knot), dan kondisi pengejaran (22 knot). OPV 80 m yang diambil sebagai objek penelitian ini menggunakan sistem diesel mechanical propulsion (DMP). Dengan penerapan sistem DMP, load factor setiap motor diesel sebagai mesin induk pada kondisi pengintaian dan kondisi patroli masing-masing hanya sebesar 7% dan 49,5%. Padahal load factor motor diesel yang diizinkan oleh engine maker berada pada rentang (60% ~ 90%) MCR. Dengan penerapan sistem propulsi hybrid, diperoleh load factor dari shaft motor pada kondisi pengintaian sebesar 87,26% dan load factor mesin induk pada kondisi patroli dan kondisi pengejaran masing-masing menjadi sebesar 62,10% dan 89,949%. Ditinjau dari aspek ekonomis, selama 30 tahun masa operasi OPV 80 m, total present value dari penerapan sistem propulsi hybrid jauh lebih rendah daripada sistem DMP dengan selisih sebesar Rp 579.205.295.632,-. ================================================================================================= As a patrol ship, the offshore patrol vessel (OPV) 80 m has an operational profile consisting several conditions: loitering (10 knots), patrol (18 knots), and interception (22 knots). Applying diesel mechanical propulsion system, load factor of each OPV 80 m’s main engine during loitering and patrol conditions in sequence is just about 7% and 49.5%. The load factor permitted by the engine maker ranges between (60% ~ 90%) MCR, however. By applying hybrid propulsion system, the load factor of the OPV 80 m’s shaft motor during loitering condition is 87.26% while the load factor of its main engine during patrol and interception conditions becomes 62.10% and 89.949%. In terms of economical aspects, for 30 years of operation period of OPV 80 m, total of present values of hybrid application is significantly much lower than of diesel mechanical application, with the difference between them is IDR 579,205,295,632,-.
