      Abstract
      Lutung jawa (Trachypithecus auratus) merupakan primata endemik Pulau Jawa yang populasinya terus mengalami penurunan akibat degradasi dan fragmentasi habitat. Penelitian ini bertujuan untuk memetakan kesesuaian habitat lutung jawa di Pulau Jawa serta mengidentifikasi faktor lingkungan yang memengaruhi distribusi lutung jawa. Pemodelan dilakukan menggunakan algoritma maximum entropy (maxent) berdasarkan 128 titik kehadiran dan 12 variabel lingkungan terpilih. Kinerja model dievaluasi menggunakan nilai Area Under Curve (AUC). Hasil penelitian menunjukkan bahwa model memiliki performa yang baik dengan nilai AUC sebesar 0,871 dan standar deviasi sebesar 0,051. Habitat lutung jawa didominasi oleh kategori kurang sesuai seluas 73.370,54 km², sedangkan habitat sangat sesuai mencakup 4243,14 km². Variabel yang memberikan kontribusi terbesar terhadap model adalah class area (31,1%) dan ketinggian (27,4%), sementara ketinggian kanopi hutan memiliki nilai permutation importance tertinggi (35,2%). Hasil penelitian dapat menjadi dasar dalam menentukan prioritas pengelolaan habitat dan upaya konservasi lutung jawa di Pulau Jawa.
       
      The Javan langur (Trachypithecus auratus) is an endemic primate species to Java Island whose population has declined due to habitat degradation and fragmentation. This study aimed to map the habitat suitability of the Javan langur on Java Island and identify environmental factors influencing its distribution. Habitat suitability modeling was conducted using the maximum entropy (MaxEnt) algorithm based on 128 occurrence records and 12 selected environmental variables. Model performance was evaluated using the Area Under the Curve (AUC). The results showed that the model had good predictive performance, with an AUC value of 0,871 and a standard deviation of 0,051. Less suitable habitat dominated the study area, covering 73.370,54 km², while highly suitable habitat covered 4243.14 km². The variables with the highest percent contribution were class area (31,1%) and elevation (27,4%), whereas forest canopy height had the highest permutation importance value (35,2%). The findings of this study can serve as a basis for habitat management prioritization and conservation efforts for the Javan langur on Java Island.
