Penelitian Analisis Kesesuaian Habitat Badak Sumatera (Dicerorhinus sumatrensis) dengan Pemodelan Maximum Entropy di Hutan Bakongan – Bengkung, Kawasan Ekosistem Leuser telah dilakukan. Penelitian ini bertujuan untuk mengetahui variabel habitat yang mempengaruhi potensial habitat badak sumatera di lokasi penelitian, mengetahui luas habitat yang potensial untuk badak sumatera di lokasi penelitian dan mengetahui kondisi habitat yang potensial untuk badak sumatera di lokasi penelitian. Pengambilan data lapangan meliputi temuan badak sumatera dan aktivitas manusia dilakukan pada bulan Agustus 2021 – Agustus 2023 dengan melakukan observasi dan penelusuran ke lokasi/jalur yang diduga lintasan badak sumatera serta menelusuri tanda – tanda bekas temuan sekunder yang ditinggalkan. Pemodelan potensial habitat badak sumatera dilakukan dengan perangkat Maximum Entropy (MaxEnt). Variabel habitat yang digunakan meliputi jarak dari jalan, jarak dari aktivitas manusia, NDVI (Normalized Difference Vegetation Index), estimasi kepadatan sungai, elevasi dan slope. Hasil analisis menunjukkan bahwa variabel habitat paling berpengaruh terhadap model potensial habitat badak sumatera yaitu elevasi dengan kontribusi 44,5%, jarak dari aktivitas manusia dengan kontribusi 24,3% dan kemiringan lereng dengan kontribusi 12,1%. Luas habitat potensial badak sumatera di kawasan Hutan Bakongan – Bengkung yaitu 23,919.91 Ha atau 32 % dari luas total.

The research on Habitat Suitability Analysis for the Sumatran Rhino (Dicerorhinus sumatrensis) using Maximum Entropy Modeling in the Bakongan-Bengkung Forest, Leuser Ecosystem Area has been conducted. This study aims to identify habitat variables that influence the potential habitat of the Sumatran rhino at the research location, determine the area of potential habitat for the Sumatran rhino in the research location, and assess the condition of potential habitat for the Sumatran rhino in the research location. Field data collection, including Sumatran rhino sightings and human activity, was conducted from August 2021 to August 2023 through observations and tracking in areas/paths suspected to be rhino trails, as well as examining signs of secondary evidence left behind. The modeling of potential Sumatran rhino habitat was performed using Maximum Entropy (MaxEnt) software. The habitat variables used included distance from roads, distance from human activity, NDVI (Normalized Difference Vegetation Index), estimated river density, elevation, and slope. The analysis results indicated that the most influential habitat variable on the potential habitat model for the Sumatran rhino was elevation, with a contribution of 44.5%, followed by distance from human activity at 24.3%, and slope at 12.1%. The area of potential Sumatran rhino habitat in the Bakongan-Bengkung Forest is 23,919.91 hectares, which is 32% of the total area.
