Pemodelan Distribusi Spasial Pohon Pakan Orangutan Sumatera (Pongo abelii) Menggunakan Maxent di Kawasan Restorasi Halaban Resor Sei Betung Kabupaten Langkat

Abstract

Food plants play a very important role in the life and survival of orangutans in their natural environment. The presence of food trees is a very important factor in controlling the growth of wild animal populations, including orangutans. The aim of this research was to analyze the spatial characteristics of the Sumatran orangutan food tree (Pongo abelii), and the habitat preferences of the Sumatran orangutan food tree (Pongo abelii) in the Sei Betung Resort Halaban Restoration, Halaban Village, Besitang District, Langkat Regency. This research was carried out in November 2023. Based on the research results, 361 orangutan food trees were found at the research location. The Area Under Curve (AUC) value of habitat suitability for orangutan food trees is 0.851 which can be classified as a good model. The largest INP value is a type of food tree, namely common marak (Macaranga indica) with a value of 91.56%. The INP value and the spatial model of orangutan food tree habitat preferences have a complementary relationship.
