      Abstract
      Salah satu kendala utama dalam implementasi kebijakan JTB adalah belum optimalnya pemanfaatan kuota akibat keterbatasan informasi spasial terkait lokasi penangkapan potensial, khususnya berbasis spesies dan wilayah pengelolaan. Penelitian ini bertujuan mengestimasi daerah potensial penangkapan tuna sirip kuning (Thunnus albacares) di WPPNRI 713 menggunakan model Maximum Entropy (MaxEnt). Data yang digunakan meliputi e-logbook tahun 2023 dan parameter oseanografi (klorofil-a, suhu permukaan laut, salinitas, tinggi paras laut, mixed layer depth, dan batimetri) yang diperoleh dari citra satelit serta diolah menggunakan SeaDAS, perangkat lunak pemetaan, dan RStudio. Hasil menunjukkan bahwa musim peralihan I (Maret–Mei) memiliki produktivitas tertinggi dengan nilai CPUE mencapai 1.476 kg/trip. Model MaxEnt menunjukkan nilai AUC rata-rata sebesar 0,87, mengindikasikan performa prediksi yang baik. Hasil peta kesesuaian habitat menunjukkan bahwa daerah dengan potensi kelimpahan tuna sirip kuning di WPPNRI 713 tertinggi cenderung muncul pada musim timur.
       
      One of the main challenges in implementing the harvest strategy policy is the suboptimal utilization of quotas due to limited spatial information on potential fishing grounds, particularly species-specific and management-area-based. This study aims to estimate potential fishing grounds for yellowfin tuna in Fisheries Management Area (FMA-RI) 713 using the Maximum Entropy (MaxEnt) model. The analysis used 2023 e-logbook data and oceanographic parameters (chlorophyll-a, sea surface temperature, salinity, sea surface height, mixed layer depth, and bathymetry) which were obtained from satellite imagery and processed using SeaDAS, mapping software, and RStudio. Results indicate that the first transitional season (March–May) had the highest fishing productivity, with a CPUE of 1,476 kg/trip. The MaxEnt model produced an average AUC value of 0,87, indicating strong predictive performance. The habitat suitability map indicates that areas with the highest potential abundance of yellowfin tuna in WPPNRI 713 tend to appear during the eastern monsoon season.
