Abstract

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 and the Javan hawk-eagle habitat environment variables. The data were then analyzed to build a Javan hawk-eagle habitat suitability model using the 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 . 9 7 and a standard deviation of 0 . 93 . Keywords: endemic, habitat, Javan hawk-eagle, maximum entropy, spatial modeling

Bromo Tengger semuru国家公园(TNBTS)是爪哇岛特有物种的栖息地，如爪哇鹰(Nisaetus bartelsi)。生态位模型(ENM)是生境空间模型的一种。本研究旨在确定爪哇鹰在TNBTS的生境适宜性。该研究于2019年9月至2020年1月进行。生境适宜性模型采用现有坐标点数据和爪哇鹰生境环境变量。利用最大熵(MaxEnt)算法对数据进行分析，建立爪哇鹰生境适宜性模型。结果表明:高生境适宜度为15,131.18 ha(30%)，中生境适宜度为11,216.61 ha(22%)，低生境适宜度为23,298.41 ha(48%)。对TNBTS中爪哇鹰生境适宜性模型的评价具有较好的模型精度，AUC值为0。97，标准差为0。93年。关键词:地方性，生境，爪哇鹰，最大熵，空间建模
