Abstract

Agroforestry has been promoted as a sustainable land-use model to reconcile agricultural production with ecosystem service provision. This study evaluates soil health indicators and their economic valuation in coffee agroforestry versus monoculture systems in Bener Meriah, Aceh, Indonesia. Forty soil samples were analyzed for physical, chemical, and biological parameters, including bulk density, porosity, soil organic carbon (SOC), total nitrogen (N), available phosphorus (P), and soil organisms. Results indicate that coffee agroforestry consistently improves soil physical, chemical, and biological properties compared to monoculture systems, leading to enhanced carbon storage, nutrient retention, and hydrological regulation. These improvements translate into higher indirect economic values of ecosystem services, highlighting the multifunctional benefits of agroforestry for sustainable coffee production. These findings confirm that coffee agroforestry enhances soil health, supports multiple ecosystem services, and delivers higher economic benefits than monoculture. Agroforestry thus represents a multifunctional and sustainable landscape model for coffee production in tropical regions.

Abstract

The forest area in Batu Bara Regency is managed by Unit X KPHL Batu Bara, which has a coastal area with coastal forest characteristics and is dominated by mangrove ecosystems. Currently, the condition of land cover in the forest area in Batu Bara Regency has undergone many changes in terms of function and designation, so an analysis is needed to determine the condition of the mangrove ecosystem. Spatial analysis was carried out to ensure the area with mangrove vegetation land cover in the Unit X Batu Bara management area, which will then be the basis for determining the location of the mangrove vegetation analysis. Based on the results of spatial analysis of changes in land cover, land cover in Unit X KPHL Batu Bara is dominated by dry land agriculture and ponds. Meanwhile, land covered with secondary mangrove forest criteria has increased in area from previously ± 297.79 Ha (8.11%) to ± 535.89 Ha (14.59%). Based on vegetation analysis, the results of the study indicate that the condition of the mangrove ecosystem in KPH Unit X KPHL Batu Bara is currently in a condition of sparse density for tree classification, moderate density for sapling classification, and dense for seedling classification with moderate species diversity.
