| dc.description.abstract | Leuser National Park (TNGL) is one of the oldest national parks in
Indonesia and home to various wildlife, especially the key habitat of Sumatran
Orangutans (Pongo abelli). The national park is divided into different zones
according to their objectives and functions. The aim of this study is to analyze
land cover changes, zones, and the distribution of Sumatran Orangutan habitat in
BPTN Region III Stabat. The research was conducted in the managed area of
BPTN Region III Stabat, Langkat Regency. The methodology used was temporal
and spatial analysis, utilizing Geographic Information System (GIS) data
processed with ArcMap 10.4 software. The land cover categories obtained include
primary dryland forest, secondary dryland forest, shrubs, plantations, open land,
water bodies, dryland agriculture, and mixed dryland agriculture. The results of
this study showed that the largest land cover area was recorded in 1990, with
primary dryland forest covering approximately 192,188.92 hectares, while the
smallest land cover area was open land, covering around 3.31 hectares. In terms
of management zones, the highest proportion of forest and non-forest classes
occurred in the core zone, with an area of approximately 673.26 hectares from
2011 to 2020, followed by a proportion of approximately 460.93 hectares in the
rehabilitation zone. The largest distribution of Sumatran Orangutan habitat
occurred in 1990, with primary dryland forest covering approximately 160,209.05
hectares. The distribution pattern underwent changes due to the conversion of
forest to plantations driven by human needs. This has disrupted the habitat of
Sumatran Orangutans and poses a threat to their survival. Collaboration between
TNGL and other conservation institutions has been established to cease
plantation activities within the habitat area, in support of conservation efforts | en_US |
