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.

Abstrak Kelompok Peternak Muda ‘Bulalo Cerdas’ di Desa Bulalo memiliki potensi sumber daya alam yang sangat mendukung kegiatan peternakan, seperti padang rumput yang luas dan ketersediaan bahan pakan lokal. Namun, potensi ini belum dimanfaatkan secara optimal karena sebagian besar peternak masih menerapkan metode konvensional tanpa dukungan teknologi tepat guna. Tantangan yang dihadapi antara lain kurangnya efisiensi dalam pemanfaatan pakan, manajemen pemeliharaan ternak yang belum sistematis, serta lemahnya sistem pengawasan kesehatan ternak. Masalah utama yang kerap muncul adalah kekurangan pakan berkualitas, terutama saat musim kemarau, yang berdampak pada penurunan produktivitas ternak sapi lokal. Program PkM ini bertujuan meningkatkan kapasitas peternak muda melalui edukasi dan pelatihan pembuatan silase pakan komplit berbasis bahan lokal. Metode pelaksanaan PkM meliputi tahap persiapan dan observasi lapangan, implementasi program berupa penyuluhan dan pelatihan, serta kegiatan monitoring dan evaluasi. Sebanyak 15 anggota kelompok “Bulalo Cerdas” berpartisipasi aktif dalam pelaksanan program ini. Hasil kegiatan pengabdian menunjukkan peningkatan signifikan dalam pengetahuan dan keterampilan mitra, khususnya dalam pengolahan silase pakan komplit sebagai solusi cadangan pakan saat musim kering. Selain itu, silase ini terbukti dapat disimpan dalam jangka panjang dan memiliki nilai ekonomis tinggi, menjadikannya alternatif pakan strategis yang mendukung keberlanjutan usaha peternakan sapi lokal. Kata kunci: pemberdayaan; peteranak muda; pelatihan dan pendampingan; silase pakan komplit; produktivitas ternak. Abstract The ‘Bulalo Cerdas’ Young Breeders Group in Bulalo Village has potential natural resources that are very supportive of livestock activities, such as vast grasslands and the availability of local feed ingredients. However, this potential has not been optimally utilised because most farmers still apply conventional methods without the support of appropriate technology. Challenges faced include a lack of efficiency in feed utilisation, unsystematic livestock rearing management, and a weak livestock health monitoring system. The main problem that often arises is the lack of quality feed, especially during the dry season, which has an impact on reducing the productivity of local cattle. This PkM programme aims to increase the capacity of young farmers through education and training in making complete feed silage based on local ingredients. The PkM implementation method includes preparation and field observation stages, programme implementation in the form of counselling and training, as well as monitoring and evaluation activities. A total of 15 members of the ‘Bulalo Cerdas’ group actively participated in the implementation of this programme. The results of the service activities showed a significant increase in partners' knowledge and skills, especially in the processing of complete feed silage as a feed reserve solution during the dry season. In addition, this silage is proven to be able to be stored in the long term and has high economic value, making it a strategic feed alternative that supports the sustainability of local cattle farming businesses. Keywords: empowerment; youth; training and mentoring; complete feed silage; livestock productivity.

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.

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.

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.
