Pemodelan Distribusi Habitat Beruang Madu (Helarctos Malayanus) Di Kawasan Pt. Alam Bukit Tigapuluh, Kabupaten Tebo, Jambi

---

The sun bear (Helarctos malayanus) is classified as Vulnerable by the IUCN. This study aims to predict the habitat suitability distribution of the sun bear and identify the environmental variables influencing it within PT. Alam Bukit Tigapuluh, Tebo Regency, Jambi. The Maximum Entropy (MaxEnt) method was employed, which is effective for modeling species distribution based on presence-only data. Sun bear presence data were obtained from WWF Indonesia and PT. ABT between 2020 and 2023, comprising a total of 37 recorded locations. Seven environmental variables were used in the modeling process, namely land cover, elevation, slope, vegetation index, and distances to roads, rivers, and settlements. The model yielded an Area Under the Curve (AUC) value of 0.985, indicating excellent model performance. Suitable habitat was predicted to cover 11,680 hectares or 53% of the PT. ABT concession area, while less suitable habitat accounted for 10,415 hectares or 47%. The most influential variables affecting distribution were distance from rivers, distance from settlements, and land cover. Sun bears tend to inhabit areas within 0–
2.5 km from rivers and show increased presence at distances of 12–15 km from human settlements. The Jackknife test of AUC values indicated that distance from rivers contributed the most to the predictive model. These findings provide essential information for the sustainable conservation and management of sun bear habitats.
Key findings: Distribution modeling, habitat conservation, maximum entropy, PT. ABT, sun bear.
