Stunting is claimed to be an issue in national development, one of the problems being that the grouping of stunting distribution areas in Larantuka District is still done manually. Therefore, one of the data clustering analyses that can be applied is using Cluster analysis and mapping. The purpose of this research is to understand the map of the distribution and clustering of stunting cases using the clustering analysis method with the SaTScan software in the Larantuka District, East Flores Regency, which is beneficial in facilitating related agencies in observing the points of stunting case distribution. This research uses a quantitative descriptive method with the aim of describing and objectively illustrating the distribution of stunting in Larantuka. The data collection methods used in this research are through literature studies related to the issues, direct interviews with the sources, and data collection on the number of stunting sufferers in Larantuka District. The analysis results indicate that 2 locations were detected in the Clustering satscan processing, namely cluster 1 with 42 cases and a P-value of 0.00000000000000001, which falls into the high category, while cluster 2 has 15 cases with a P-value of 0.0000000000000033, which falls into the low category. If the P-value is less than 0.05, it shows strong evidence that these clusters have high significance.

The still-rarely-known Rana Masak Hot Spring Natural Tourism Area is a problem in itself. Therefore, an appropriate strategy is needed in the development of the Rana Masak Natural Tourism Area. The method used is a Mixed method, with data collection techniques through observation, documentation, interviews and questionnaires. The results of the study show that the Rana Masak Hot Spring Natural Tourism Area has visual attractions including: hot springs at more than one point, golden yellow limestone rock formations, panoramic rice fields and rivers that soothe the eyes of tourists. Accessibility conditions are still inadequate because they still use dirt paths. The condition of the available amenities is only a park equipped with chairs in a state of disrepair. The strategy that must be implemented is to support an aggressive growth policy by using existing strengths to take advantage of existing opportunities and the development of the Rana Masak Hot Spring Natural Tourism Area is further optimized by strengthening the construction of facilities and accessibility as well as increasing promotion by collaborating with local influencers so that it can become a favorite and sustainable tourist destination.

As urbanization continues to grow in the Jabodetabek region, particularly in Depok where the University of Indonesia is located, surface air temperature has increased. This study aims to examine how land cover changes over time influence temperature in this area. Using Landsat 8 OLI/TIRS Collection 2 Tier 1 satellite data, thermal bands (TIRS) were used to extract Land Surface Temperature, while multispectral bands (OLI) were used to generate vegetation indices. Data processing was carried out using Google Earth Engine to obtain LST values for the University of Indonesia. The results show a temperature increase of 4.36°C over 12 years from 2013 to 2025. This rise correlates with land cover transformation driven by infrastructure development in the main campus area. A clear spatial pattern is observed: northern areas exhibit lower temperatures due to dominant vegetation and water bodies, while southern areas show higher temperatures due to built-up areas, asphalt roads, and impervious surfaces. The study concludes that land cover change at the University of Indonesia significantly contributes to the increase in Land Surface Temperature.

This study analyzed drought vulnerability levels in Giricahyo Village, Gunungkidul Regency, Special Region of Yogyakarta, using a Geographic Information System (GIS) approach. The karst area, characterized by porous geological features, results in limited surface water availability, particularly during the dry season. The research method involved collecting spatial and non-spatial data, including rainfall, soil type, slope gradient, geology, and land use, which were processed using GIS-based overlay techniques. The results showed that Giricahyo Village is classified into five drought vulnerability levels, dominated by low (7.986 km²) and moderately low (4.897 km²) vulnerability, while high vulnerability (1.598 km²) was found in steep-sloped areas with porous Lithosol soil. The primary contributing factors were the combination of steep slopes, Lithosol soil, and suboptimal rainwater absorption due to karst geology. Field validation confirmed a 42.5% consistency between predictions and actual conditions, with discrepancies mainly in areas with piped water supply (PAM) infrastructure. Community adaptation through rainwater harvesting and clean water distribution proved effective in mitigating drought impacts. This study recommends drought mitigation-based spatial planning and sustainable water resource management for karst region.

The potential of a region can be explained through the base sector, which is a sector that is able to fulfill local needs and be exported outside the region. Geographic Information System (GIS) is used to present spatial data of regional potential in the form of maps. This research was conducted in North Konawe Regency to identify leading sectors and their spatial distribution. Data were obtained through interviews and observations, then analyzed using the Location Quotient (LQ) and Dynamic Location Quotient (DLQ) methods. The analysis showed that the current leading sectors are agriculture, forestry and fisheries (LQ = 1.75) in Lasolo Sub-district; mining and prospecting (LQ = 1.02) in Langgikima Sub-district; and health services and social activities (LQ = 1.19) in Asera Sub-district. Potentially leading sectors in the future are mining and sedimentary (DLQ = 1.04) and processing industry (DLQ = 4.02). These findings can serve as the basis for development planning based on regional potential.

High rainfall and changes in land use to built-up areas in the Wanggu watershed have reduced the soil's ability to absorb water and increased surface runoff, potentially causing flooding. This study aims to identify land use changes in 2014 and 2022, predict conditions in 2030, and analyze flood potential in these three periods using overlay methods and the Land Change Modeler. The results show that forest land experienced the largest decrease in 2014–2022, amounting to 2,048.30 ha, and is predicted to decrease again by 1,591.85 ha by 2030. Conversely, the smallest changes occurred in water bodies and plantations. Flood potential in 2014 was dominated by the no potential category, while in 2022 it shifted to the low category. Predictions for 2030 show the greatest flood potential in the moderate category, while the very high category has the smallest area coverage. These findings confirm that land use dynamics have a significant influence on increasing flood risk.

The rapid population growth in Batam City has led to the conversion of green land into a built area to meet residential, industrial, and infrastructure needs. This change in land use has an impact on increasing surface temperature and triggers the Urban Heat Island (UHI) phenomenon. UHI is characterized by higher temperatures in urban areas compared to surrounding areas due to changes in land cover. This study aims to identify land surface temperature, UHI phenomenon, building density level (NDBI), and the influence of NDBI on UHI on Batam island. The results showed significant variations in land surface temperatures across the island, with a range between 18°C to 33°C. This temperature difference directly contributes to the formation of the UHI phenomenon on Batam Island. The NDBI map of Batam Island shows that the UHI phenomenon tends to be concentrated in areas with high building densities such as in urban center, industrial and residential areas. The regression results between NDBI and UHI showed the influence of NDBI on UHI by 71%, which shows that the relationship between the UHI and NDBI variables has a positive and proportional relationship. The results also show that the higher the density of the building, the intensity of the UHI will also increase. This study confirms that the increase in building density is the factor that encourages the occurrence of the UHI phenomenon in Batam Island.

This study aims to analyze the distribution and productivity of sago plants (Metroxylon sp) on peatlands in the Meranti Islands Regency as an effort to support the green economy and ecosystem conservation. Peatlands have an important ecological function as carbon storage, water regulation, and biodiversity habitats, but their use often causes degradation. Sago, which naturally grows on peatlands, is a strategic local commodity with high economic and ecological value. Research data were sourced from the Central Bureau of Statistics (BPS) in 2022 for land area and sago production, as well as shapefile data on administrative boundaries and peatland distribution from geospatial sources. Quantitative methods were used to calculate sago productivity, while spatial analysis was conducted by overlaying maps of peatlands, rivers, and sago distribution. The results show that the average sago productivity in Meranti is 6.15 tons/ha, which is considered low, Even though districts with large land areas show high potential. The overlay map shows the integration between sago distribution and peatland ecology, as well as the support of small rivers in maintaining moisture. This study emphasizes the need for intensive management, cultivation technology, and land use diversification to increase productivity while preserving ecosystem sustainability, so that sago can become a sustainable flagship commodity in the Meranti Islands.

ANALISIS ALIH FUNGSI LAHAN DAN PENGARUHNYA TERHADAP EKOSISTEM PESISIR PANTAI SANTOLO DI KABUPATEN GARUT

Isti zabatuddawat — Sat, 27 Dec 2025 00:01:16 +0000

This study aims to analyze changes in land use and its impact on the coastal ecosystem in the Santolo Beach area, Garut Regency. The method used is descriptive qualitative with indirect observation through searching various digital sources, such as photos, videos, tourist reports, news articles, and data from related agencies to see the interaction between coastal ecological aspects and tourism development activities. The results of the study indicate that land use changes in Santolo Beach have triggered abrasion and accretion due to the reduction of coastal vegetation as a natural protector, accompanied by increased pollution from plastic waste and domestic waste that threaten marine biota such as small fish, mollusks, and coral reefs. This condition has an impact on decreasing fishermen's catches, increasing the vulnerability of tourism infrastructure to abrasion, and causing ecological and socio-economic pressures. The main factors causing land use changes include economic drivers, social changes in society, and weak spatial planning regulations. Therefore, an ecotourism-based management strategy and community involvement in conservation are needed to maintain a balance between tourism development and the sustainability of the Santolo Beach coastal ecosystem.

Tourism development in South Kuta Subdistrict has driven an increase in construction activities for residential needs, infrastructure, and supporting tourism facilities. These activities have led to the growing potential of critical land in the South Kuta Subdistrict. This study aims to determine the distribution and area of critical land in South Kuta Subdistrict. The data used in this study includes administrative maps, forest area maps, erosion maps, land use maps, and slope maps. A few methods used included overlay and scoring of maps based on parameters. The study results showed that the non-critical land area is 4.212,16 ha, potentially critical land is 2.601,51 ha, moderately critical land is 3.197,24 ha, and critical land is 102.08 ha. The non-critical land classes tends to dominate the northern part, while the critical land is more spread out in the southern part. The northern part is the area that developed earlier with more structured planning, such as the Nusa Dua area. Critical land requires prioritized handling by implementing appropriate conservation techniques to prevent further damage. Conservation efforts that can be made include planting ground cover plants to prevent surface erosion, and the government’s role is essential in enforcing building permits on critical lands.
