Pemetaan Dan Analisis Spasial Persebaran Tumbuhan Invasif Langkap (Arenga Obtusifolia) Di Cagar Alam Rimbo Panti

---

ABSTRACT
Rimbo Panti Nature Reserve is a vital conservation area in West Sumatra that faces ecological threats from invasive plant species, notably Arenga obtusifolia (langkap). This species exhibits high regenerative capacity and spatial dominance, potentially disrupting local biodiversity. This study aims to map the distribution and analyze both the spatial patterns and environmental factors influencing the presence of A. obtusifolia in the reserve. Field surveys were conducted to record langkap occurrence points, and spatial modeling was carried out using the Maximum Entropy (MaxEnt) approach, complemented by spatial pattern analysis via the Nearest Neighbor Index (NNI). Results reveal that langkap exhibits a clustered distribution pattern, predominantly in hill forest habitats. Environmental variables with the greatest influence on langkap distribution include slope, distance from rivers, and elevation. The MaxEnt model demonstrated high predictive performance, with an AUC (Area Under Curve) value of 0.899. Habitat suitability mapping categorized the area into unsuitable (56%), low (29%), moderate (8%), and high (7%) suitability classes. These findings provide critical insights for managing and controlling invasive species to preserve the ecological integrity of the conservation area.
