Abstract
Kapal perang jenis korvet memegang peranan vital dalam pertahanan laut, namun seiring bertambahnya usia operasional, sistem propulsi eksisting (konfigurasi CODOG) mengalami penurunan performa, peningkatan konsumsi bahan bakar, serta kendala dalam pemeliharaan suku cadang turbin gas. Kondisi tersebut menyebabkan konfigurasi propulsi eksisting menjadi tidak optimal dalam memenuhi tuntutan efisiensi operasional dan kesiapan tempur. Penelitian ini bertujuan untuk menentukan konfigurasi sistem propulsi yang paling optimal dalam program repowering kapal korvet dengan menggunakan pendekatan Analytical Hierarchy Process (AHP). Metodologi penelitian melibatkan pengumpulan data teknis, pemodelan hidrodinamika untuk menghitung hambatan dan kebutuhan daya, serta simulasi stabilitas kapal. Tiga alternatif sistem propulsi dievaluasi, yaitu Twin Engine, CODAD (Combined Diesel and Diesel), dan CODAE (Combined Diesel and Electric). Kelima kriteria utama yang digunakan dalam penilaian AHP meliputi kecepatan kapal (Vs), mode operasi, ketahanan (endurance), rasio biaya operasional, dan redundancy. Hasil kajian teknis dan optimasi menunjukkan bahwa konfigurasi dengan pitch propeller sebesar 90% merupakan kondisi paling optimum untuk menghindari fenomena kavitasi, dengan pemilihan daya mesin sebesar 4.300 kW pada 2.100 rpm. Berdasarkan pengolahan data dari 34 responden ahli menggunakan metode AHP, alternatif Twin Engine memperoleh nilai preferensi tertinggi dengan nilai Sum Product sebesar 5,30, menempati peringkat pertama dibandingkan CODAD (5,21) dan CODAE (4,99). Penelitian ini menyimpulkan bahwa konfigurasi Twin Engine adalah rekomendasi terbaik untuk program repowering karena mampu memberikan keseimbangan optimal antara peningkatan kinerja teknis, efisiensi biaya, dan keandalan operasional jangka panjang.

Corvette-type warships play a vital role in naval defense; however, as their operational age increases, the existing propulsion system (CODOG configuration) experiences performance degradation, increased fuel consumption, and constraints in gas turbine spare part maintenance. These conditions cause the existing propulsion configuration to become suboptimal in meeting the demands of operational efficiency and combat readiness. This research aims to determine the most optimal propulsion system configuration for a corvette warship repowering program using the Analytical Hierarchy Process (AHP) approach. The research methodology involves technical data collection, hydrodynamic modelling to calculate resistance and power requirements, and ship stability simulations. Three propulsion system alternatives were evaluated: Twin Engine, CODAD (Combined Diesel and Diesel), and CODAE (Combined Diesel and Electric). Five main criteria used in the AHP assessment included ship speed, operation modes, operational endurance, operational costs, and redundancy. The technical study and optimization results indicate that a configuration with a 90% propeller pitch is the most optimum condition to avoid cavitation phenomena, with a selected engine power of 4,300 kW at 2100 rpm. Based on the data processing from 34 expert respondents using the AHP method, the Twin Engine alternative obtained the highest preference value with a Sum Product score of 5.30, ranking first compared to CODAD (5.21) and CODAE (4.99). This research concludes that the Twin Engine configuration is the best recommendation for the repowering program because it provides an optimal balance between technical performance enhancement, cost efficiency, and long-term operational reliability.
