The purpose of this study is to determine the land suitability class for durian plants and the factors that affect land suitability for land classes in the region. This research was conducted in Papualangi Village with a height of 226 meters above sea level and is located on the edge of a public road to Cempaka Putih village. Location is chosen based on the presence of outcrops that can facilitate the conduct of research on land on the ground. To analyze the existence of land suitability in Papualangi village, there are several plants such as durian, rambutan, langsat / duku, cocoa, cloves, etc. This research was conducted using direct observation methods in the field to produce quantitative data. The results obtained are different land suitability levels for each factory and the determinants of land suitability are different from each other. From the results obtained it can also be concluded that the soil in Papualangi village is suitable for planting durian, rambutan, cloves, cocoa, robusta coffee, coconut and strawberry, and is more suitable for growing crops such as langsat, corn and tea. Land suitability can be affected by temperature, drainage, texture, nutrient retention, available nutrients, and land slope.

In the Alo sub-watershed, the study compares the rates of various types of land use. The Alo sub-watershed is 7,959.98 areas in total. Measurement of infiltration rates for various land uses in the Alo sub-watershed and analysis of differences in infiltration rates for various land uses in the Alo sub-watershed are the problems at hand in this study. The Horton method was used in this study's infiltration measurements. This approach uses a model of time-dependent empirical equations. It is known that multiple infiltration categories exist for plantations, villages, vacant land, bushes, and woods in the infiltration rate class for the kind and usage of dry land used in this study's Alo sub-watershed. It has classes for Fast, Moderate, and Moderate infiltration rates. For the type of land use and paddy field, the infiltration rate falls into the category of being fairly slow. This is due to the high water content of paddy fields, which makes the infiltration process take a while to complete. As a result, the infiltration rate in the Alo sub-watershed, Tibawa District, Gorontalo Regency, and Gorontalo Province reveals that the medium class dominates in the Alo sub-watershed. The cumulative infiltration rate or total amount of infiltrated water is 123,899 mm/hour at point 14 types of vacant land, and 8,476 mm/hour at point 16, which is the smallest cumulative value. The infiltration rate class in the Alo sub-watershed, Tibawa District, Gorontalo Regency, and Gorontalo Province reveals that the Medium Class dominates the sub-watershed.

Alo Watershed Gorontalo Regency is one of the biggest contributors to watershed sedimentation in Limboto Lake, so it is necessary to conduct research on the distribution of erosion vulnerability levels in Alo Watershed. This study aims to determine the Analysis of the Distribution of Erosion Vulnerability Levels in the Alo Watershed Area, using the USLE (Universal Soil Loss Equation) method by finding the value of A, namely the amount of erosion that is influenced by rainfall (R), soil type (K), slope (LS). ), land use (C), and conservation measures (P) the calculation is the value of A = R x K x LS x C x P. The research results show that the total amount of erosion in the Alo Watershed area is 458,898.35 Ton/Ha/Year. Land use in the Alo watershed area is dominated by moorland or fields, therefore, to reduce the rate of erosion, land conservation measures are needed, for example changing land management habits by making bench terraces. Bench terraces can reduce the length of the slope and hold water so that it can reduce the speed of water flow on the surface.

One of the new tourist objects in North Gorontalo Regency is Diyonumo Island and until now it has not been optimally developed both in terms of its feasibility as a tourist area. So it really needs intervention from both the government and the private sector to encourage tourism development in North Gorontalo Regency which is based on nature. But there is no information system that provides an overview of this tourism potential. So the researchers identified the tourism potential of Diyonumo Island using a geographic information system in North Gorontalo Regency. The method used in this study was SWOT integrated with a spatial approach to analyze each parameter, namely attractions, infrastructure and accessibility. Based on spatial mapping, Diyonumo Island tourism can be recommended as a strategic tourism area for Gorontalo Province. The results of the analysis show that Diyonumo Island has a percentage of 40% of tourist attractions that have the potential to be developed and become a supporting strategy to increase the number of tourist visits.

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.

Reviewing spatial planning is a must in planning and regional development, besides that, it is also to obtain information related to the suitability of the use of space that has been used. Spatial planning assessment can be based on a tendency towards spatial use and based on land use and spatial function. Techniques and kali have been carried out using spatial analysis with the concept of geographic information systems that cannot be separated from the research parameters used. The method used is a mixed method that combines quantitative and qualitative methods. The quantitative method functions to produce numerical data so that it can be interpreted into a narrative, while qualitative methods are used to describe either numerical data, tables, pictures, or maps into useful narrative information based on the results of the research that has been done. The purpose of this study is to see the progress in the implementation of space suitability in the campus environment of the Muhammadiyah University of Gorontalo. The result of the research shows that the campus area can be classified based on the length of space, which includes the appropriate area in the built area of 1,81537 ha, the undeveloped area of 7,23050 ha and the unsuitable area is in the built area of 0.04513 ha. In addition to producing information related to space suitability, the research results also provide recommendations regarding the plan to use campus space as an alternative for future development.

Paguyaman watershed is the second largest watershed in Gorontalo province with an area of 3,485.65 which is a critical watershed. There is a problem of sedimentation in the watershed causing the river flow rate to slow down. It is hoped that it can be used as an alternative to overcome siltation. The research aims to estimate the amount of sedimentation and determine the spatial distribution of sedimentation in the Paguyaman sub-watershed, the method used is the Soil and Water Assessment Tool (SWAT) model. carried out with the help of geographic information systems (GIS) with ArcGIS 10.4 software, SWAT can describe hydrological processes (sedimentation). DEM data resolution (10x10) as the main input for the DAS delineation process. Soil data, land use, soil type, determines the land unit/hydrologic response unit (HRU) of the watershed. Rainfall and climate data (temperature, average humidity, solar intensity, wind speed) obtained from stations spread over the area are integrated into SWAT to calculate sedimentation. The results of the Paguyaman watershed have a very steep slope (> 40), land use is dominated by primary and secondary dryland forest with a total area of 49511.90 with a percentage of 45.39%, Tropudults soil type; Dystropepts area of 22125.96 with a percentage of 20.28%, DAS Paguyaman has 8202 HRU's and sub-basin 475 there are 5 classifications of sedimentation quantities, namely very high sedimentation 285.25 ha, with a percentage of 0.26%, high sedimentation 87.78 ha with a percentage of 0.08%, moderate sedimentation 505.94 ha with a percentage of 0.45%, low sedimentation 3040.37 ha a percentage of 2.79% and very low sedimentation 105171.27 ha with a percentage of 96.41%.

The failure of top-down conservation in natural resource management continues to provoke resistance led by local communities. This study analyzes how the coastal community of Torosiaje constructs a polycentric governance system through collective action in response to ecological crises and to the state's appropriation of living space, aiming to achieve blue justice in the management of marine and coastal resources. The complex, polycentric governance in joint management involves various actors, including the state, local communities, and the private sector, who collectively play active roles in decision-making for sustainability. Meanwhile, blue justice requires the fair distribution of natural resources and ecosystem benefits, which is pursued through the collective struggle of the community against ecological injustice. Using social movement and political ecology theories as an analytical framework, this research redefines Community-Based Natural Resource Management (CBNRM) as a more inclusive and responsive model to local dynamics. A qualitative case study design was employed through in-depth interviews, participant observation, and document analysis, which were subsequently analyzed thematically. The findings reveal that integrating local knowledge and formal rules, embodied in the paddakuang and sipakullong conservation groups, results in a more adaptive and just CBNRM model in response to resistance. Cross-village collaboration, participatory ecotourism, and culture-based education strengthen the socio-ecological dimensions of this polycentric governance. This study contributes theoretically by applying social movement theory to redefine successful CBNRM. It argues that sustainable governance is a political outcome shaped by community resistance to ecological injustice and state dispossession, rather than merely a technical model.
