Abstract

Watershed degradation poses a serious threat to water availability, ecosystem sustainability, and human well-being. This study aims to identify and analyze the spatial distribution patterns of three key water-regulating plant species Pterospermum javanicum, Ficus spp., and Dendrocnidae decumana in the upstream area of the Babak Watershed, Lombok, Indonesia. Field data were collected through exploratory surveys and analyzed using the Average Nearest Neighbor (ANN) method in ArcGIS 10.8. The results reveal distinct spatial patterns: D. decumana exhibits a random distribution (R = 0.925), while Ficus spp. (R = 0.667) and P. javanicum (R = 0.698) show clustered patterns. These patterns reflect ecological adaptations such as tolerance to environmental heterogeneity or vegetative reproduction strategies. Despite differences, all three species significantly contribute to watershed hydrology by enhancing infiltration, reducing surface runoff, and stabilizing soil. Spatial analysis of vegetation distribution provides essential insights for data-driven watershed management and supports targeted conservation strategies in ecologically sensitive upstream zones.

Abstract

Karang Sidemen Village plays an important role in protecting and preserving the rich biodiversity around the Mount Rinjani area, especially in the use of medicinal plants as an inseparable part of the "Gumi Sasak" cultural heritage. This service aims to document the potential of medicinal plants along the tourist route through the creation of distribution maps and plant pocket books. This service is carried out using the Community Based Participatory Research (CBPR) method which includes steps such as: initial coordination, socialization, exploration, data analysis, and submission of service results. The result of this service was that 82 families, 253 genera and 303 species were obtained with a total number of plant individuals found along the Karang Sidemen village tourist route of 8,139 individuals, of which 25 plant species were selected for making a draft pocket book and at the same time making a distribution map into a 2D map.
