Bromo Tengger Semeru National Park (TNBTS) is a conservation area as the habitat of endemic species in Java Island, such as the Javan hawk-eagle (Nisaetus bartelsi).One of the spatial models of habitat is the Ecological Niche Modeling (ENM) approach.This study aimed to determine habitat suitability for the Javan hawk-eagle in TNBTS.The research was conducted from September 2019 to January 2020.

The habitat suitability model used the present coordinate point data Greens Supplements and the Javan hawk-eagle habitat environment variables.The data were then analyzed to build a Javan hawk-eagle habitat suitability model using the Simpsons Maximum Entropy (MaxEnt) algorithm.The results showed three models of habitat suitability categories, i.e.

: high of 15,131.18 ha (30%), medium 11,216.61 ha (22%), and low 23,298.41 ha (48%).

The evaluation of the Javan hawk-eagle habitat suitability model in TNBTS has an excellent model accuracy with an AUC value of 0.97 and a standard deviation of 0.93.Keywords: endemic, habitat, Javan hawk-eagle, maximum entropy, spatial modeling.
