PEMETAAN PENYEBARAN STUNTING DENGAN SISTEM CLUSTERING SATSCAN DI KECAMATAN LARANTUKA KABUPATEN FLORES TIMUR

Antonius Boy — 2025-12-21

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.

KETERKAITAN LAND SURFACE TEMPERATURE DENGAN LANDCOVER DI UNIVERSITAS INDONESIA PADA TAHUN 2013 DAN 2025

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.

PERAN EKOSISTEM MANGROVE SEBAGAI PENOPANG KEANEKARAGAMAN HAYATI LAUT DAN KEBERLANJUTAN LINGKUNGAN DI WILAYAH PESISIR DESA SEI NAGA LAWAN, KEC. PERBAUNGAN, SUMATERA UTARA.

Mangrove ecosystems are one of the most important living systems in coastal areas, especially in Sei Naga Lawan Village. Mangroves function as a transitional area between land and sea, which not only protects the coast from the risk of abrasion and erosion, but also provides crucial shelter for various types of marine life. Using a descriptive qualitative approach to describe the role of mangrove ecosystems in supporting marine biodiversity and their contribution to environmental sustainability, this research collected data through field observations, interviews, and literature review. It is hoped that the results of this research will be able to explain the role of mangrove ecosystems in maintaining marine biodiversity and environmental sustainability in Sei Naga Lawan Village. The purpose of the research is to explain the role of mangrove ecosystems in maintaining marine biodiversity and explain the socio-economic benefits of this mangrove ecosystem. of mangrove ecosystems in maintaining marine biodiversity and explain the socio-economic benefits of this mangrove ecosystem.

ANALISIS RAWAN KEKERINGAN DI DESA GIRICAHYO, KECAMATAN PURWOSARI, GUNUNG KIDUL

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.

ANALISIS SEBARAN POTENSI SEKTOR UNGGULAN MENGGUNAKAN METODE LQ (LOCATION QUESTION) DAN DLQ (DYNAMIC LOCATION QUOTIENT) DI KABUPATEN KONAWE UTARA

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.

PEMODELAN POTENSI BENCANA BANJIR BERDASARKAN PERUBAHAN PENGGUNAAN LAHAN DI DAS WANGGU

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.
