Abstract

Dalam era globalisasi, perkembangan teknologi maritim mendukung kebutuhan kapal patroli yang cepat dan efisien. Kapal patroli memiliki peran penting dalam menjaga keamanan perairan, melakukan pencarian dan penyelamatan, serta mengawasi aktivitas ilegal. Dengan tantangan kejahatan laut yang semakin canggih, aparat penegak hukum membutuhkan kapal patroli dengan performa optimal. Mayoritas kapal patroli di Indonesia masih menggunakan sistem propulsi konvensional. Penelitian ini bertujuan menganalisis efisiensi penggunaan Surface Drive System (SDS) pada Very Fast Patrol Boat (VFPB) 18 meter dengan kecepatan service 50 knot, dibandingkan sistem propulsi awalnya Stern Drive. Analisis teknis dilakukan menggunakan software Maxsurf, sedangkan analisis ekonomi mencakup biaya operasional dan investasi. SDS divariasikan dengan pembuatan cekungan (notch) pada transom dengan empat kedalaman yaitu 110 mm, 220 mm, 330 mm, dan 440 mm. Hasil penelitian menunjukkan bahwa SDS dengan cekungan 440 mm merupakan konfigurasi paling efisien. Pada kecepatan 50 knot, SDS variasi keempat membutuhkan daya 1329,11 kW, jauh lebih rendah dibandingkan Stern Drive yang memerlukan daya 1693,21 kW. Efisiensi propeler SDS mencapai 62%, mendukung operasi kapal secara efektif. Dan untuk konsumsi bahan bakar tiap tahun, VFPB dengan sistem propulsi SDS mengkonsumsi bahan bakar sebanyak 214.252 liter/tahun dengan biaya Rp 3.920.814.284,29, lebih hemat dibandingkan Stern Drive yang mengkonsumsi bahan bakar sebanyak 272.945 liter/tahun dengan biaya Rp 4.994.890.834,94. Dengan demikian, SDS mampu mengurangi konsumsi dan biaya bahan bakar hingga 22%. Berdasarkan Compound Annual Growth Rate (CAGR), SDS menunjukkan pertumbuhan positif sebesar 2,3% pada tahun ke-20. Hal ini menunjukkan bahwa SDS lebih efisien secara teknis maupun ekonomis dibandingkan Stern Drive, sehingga SDS menjadi alternatif unggul untuk meningkatkan performa kapal patroli.

In the era of globalization, advancements in maritime technology support the need for fast and efficient patrol boats. Patrol boats play a crucial role in maintaining maritime security, conducting search and rescue operations, and monitoring illegal activities. With increasingly sophisticated maritime crimes, law enforcement agencies require patrol boats with optimal performance. Most patrol boats in Indonesia still utilize conventional propulsion systems. This study aims to analyze the efficiency of using the Surface Drive System (SDS) on an 18-meter Very Fast Patrol Boat (VFPB) with a service speed of 50 knots, compared to its initial Stern Drive propulsion system. The technical analysis was conducted using Maxsurf software, while the economic analysis covered operational and investment costs. The SDS was varied by creating a notch on the transom with four depths: 110 mm, 220 mm, 330 mm, and 440 mm. The results indicate that the SDS with a 440 mm notch is the most efficient configuration. At a speed of 50 knots, the fourth SDS variation requires 1,329.11 kW of power, significantly lower than the Stern Drive, which requires 1,693.21 kW. The propeller efficiency of the SDS reaches 62%, effectively supporting the vessel's operations. In terms of annual fuel consumption, the VFPB with the SDS propulsion system consumes 214,252 liters per year at a cost of IDR 3,920,814,284.29, which is more economical compared to the Stern Drive, which consumes 272,945 liters per year at a cost of IDR 4,994,890,834.94. Thus, the SDS can reduce fuel costs by up to 22%. Based on the Compound Annual Growth Rate (CAGR), the SDS shows positive growth of 2.3% in the 20th year. This demonstrates that the SDS is more efficient both technically and economically compared to the Stern Drive, making it a superior alternative for enhancing patrol boat performance.
