The Pakpak Bharat Regency is essential to the Sumatran Orangutan's ecosystem.The Sumatran Orangutan protects other plants and animals in the forest ecosystem as an umbrella species.Unfortunately, species are listed as Critically Endangered due to habitat fragmentation, exploitation, and conversion to other land uses.Lagan-Pagindar Road construction cutting through forest areas in Pakpak Bharat impacts the fragmentation of the Sumatran Orangutan habitat.This study aims to evaluate the landscape structure of the impact of the Lagan-Pagindar Road construction on the Sumatran Orangutan habitat.The methods used are land cover analysis by supervised classification in ArcMap10.8,distance from human activity areas using Euclidean distance tools in ArcMap10.8,and spatial fragmentation analysis using landscape metric by patch analyst Extension ArcGIS.Land cover change of the Sumatran Orangutan habitat between 2003 and 2022 shows an increase in the area of land cover classes related to human activities.The impact of the Lagan-Pagindar Road has caused the Sumatran Orangutan's habitat to become fragmented.The threat of habitat fragmentation must be minimized by mitigating the impact of road construction.Planning and conducting a thorough assessment of infrastructure development is necessary to minimize the adverse effects of conserving Sumatran Orangutan.
