Abstract

Ethnoecology is a science that studies the relationship between humans and the environment. This relationship is related to the use of natural resources around them to continue life using local wisdom, namely the agroforestry system. Ecologically, economically, and socially, the agroforestry system planting patterns can help reduce soil fertility degradation due to human activities that exceed the carrying capacity of the land. The aim of the research was to determine land management and manifestations of land management for durian plants that implement the agroforestry system. The research used qualitative methods with techniques namely collecting data, analyzing data, and drawing conclusions. Data collection used snowball sampling techniques with an unlimited number of respondents. The results explain that (1) land management, tillage, fertilization, crop rotation, and fallow periods on durian plantations have not been managed optimally, resulting in the production of durian plants not being optimal; (2) the manifestation of land management is divided into two, namely traditional and semi-traditional agroforestry systems and these two systems have differences in land management, namely organic and non-organic. Keywords: agroforestry systems, durian, ethnoecology, land management

Abstract

Equitable spatial access to health services is a key indicator of public service performance and territorial justice. This study analyzes the spatial distribution pattern and service catchment of government health facilities in Gorontalo Regency, Indonesia, using Geographic Information Systems (GIS). A spatially oriented descriptive-quantitative design was applied. Facility location coordinates were collected via GPS field survey and combined with secondary administrative and population data. ArcGIS 10.5 was used for two core analyses: (1) Average Nearest Neighbor to evaluate spatial distribution; and (2) buffer analysis to classify service accessibility into four distance bands (0–1,000 m; 1,001–2,000 m; 2,001–3,000 m; >3,000 m) with reference to national planning guidelines. Results show a dispersed distribution pattern (T = 1.421; p < 0.01), indicating facilities have been placed to avoid clustering. Accessibility mapping reveals that 56.89% of settlement area lies within the “moderate” (1–2 km) service band, whereas 4.99% remains beyond 3 km, suggesting residual spatial inequality. Large, sparsely settled districts such as Asparaga exhibit wide catchments served by a single primary facility, highlighting potential service strain and travel burden. Findings demonstrate the operational value of GIS for rapid spatial equity assessment in subnational health planning. The study’s novelty lies in integrating Nearest Neighbor statistics with policy-referenced distance buffers using current, field-verified facility coordinates in a rural-regency context.

Abstract

The Paguyaman Watershed represents a strategically significant and essential water resource for the surrounding region. In recent years, this area has become increasingly vulnerable to environmental pressures, including heightened sedimentation, changes in land use, declining water quality, and more frequent flooding events. This study aims to evaluate the morphometric characteristics of the Paguyaman Watershed and their relationship to flood vulnerability observed over the past five years. Morphometric analysis was conducted using quantitative methods within GIS and remote sensing approach. The primary dataset utilized was DEMNAS. The analyzed morphometric parameters include drainage density (3.95), stream frequency (8.61), bifurcation ratio (8.41), form factor (0.13), elongation ratio (0.40), and ruggedness number (8.20). These parameter values indicate that the Paguyaman Watershed possesses an elongated concave shape, steep topography, high surface runoff intensity, and low infiltration capacity. The findings reveal that the watershed exhibits characteristics of high flood susceptibility, as evidenced by recurrent flood events in the villages of Totopo, Tolite, and Juria over the last five years. The spatial pattern of flood vulnerability within the watershed is closely linked to morphological features, such as steep slopes, low soil infiltration capacity, and excessive surface flow accumulation—particularly within the Bilato and Boliyohuto sub-districts.

Abstract

This study conducts a comparative morphometric analysis of the Alo and Molamahu sub-watersheds, located in the upstream Limboto Watershed, Gorontalo Province, Indonesia, to assess flood risk. Using the National Digital Elevation Model (DEMNAS) with an 8-m spatial resolution, classical morphometric parameters were derived through remote sensing and Geographic Information System (GIS) techniques. Both sub-watersheds share a maximum stream order of 4 and exhibit relatively high drainage density and stream frequency, indicating rapid surface runoff. However, the Molamahu sub-watershed is larger, steeper, and has a higher ruggedness number than Alo, suggesting greater erosion potential and higher susceptibility to landslides and flash floods. In contrast, Alo shows gentler slopes but remains flood-prone due to short overland flow paths. The analysis demonstrates that morphometric characteristics directly influence flood dynamics, highlighting the need for tailored watershed management. Recommended strategies include erosion control and slope stabilization in Molamahu, and water retention measures in Alo, supported by broader reforestation efforts across the Limboto system.
