Abstract

Transformation of suburban areas into urban areas often results in the phenomenon of urbanisation which indirectly causes an increase in the dynamics of land use land cover (LULC) changes and changes in the distribution and intensity of Land Surface Temperature (LST). In this study, we examined the relationship of LULC dynamics to the spatial pattern of LST in Surakarta City through Landsat 8 OLI and TIRS image data in 2020 and 2024. Determination of LULC dynamics is done through supervised classification method, and single channel algorithm method to regress thermal data into spatial distribution of Surakarta City LST. The results of LULC and LST processing were spatially regressed using Geographically Weighted Regression (GWR) features to see the correlation and statistical calculations to see the level of surface temperature in each land use class. The results showed a positive change in built-up area which includes residential and non-residential buildings of 6.59 hectares in 2024, while vegetation land experienced a negative change of 487.72 hectares. LST processing results show changes in maximum and minimum temperatures, with a range of 23-30.1oC in 2020 to 24.85-30.5oC in 2024. Spatially, the maximum surface temperature distribution is on residential built-up land, while the lowest surface temperature is on vegetation land, especially non-agricultural vegetation. The results of this study can help the government in creating a spatial layout of Surakarta City that pays attention to the environment through the development of green spaces in several high-class locations.

Abstract

Located in Labanu Village, Tibawa District, Gorontalo Regency. The rocks contained in the study area are rocks originating from the Bilungala Volcano rock formation. This study aims to identify lithofasies of volcanic rocks based on differences in composition, structure, and texture. The method used is Measured Section (MS), in reducing the cross-section of measured stratigraphy, petrographic and petrological analysis carried out to divide the lithofasies of volcanic rocks. Lithofasies in the study area are divided into two lithofasies, namely: Lava lithofasies and pyroclastic lithopasies. In andesite facies lava lithofasies characterized by greenish-gray color, porphyritic texture, massive structure, degree of crystallization in andesite rocks is holocrystalline Most are composed of crystals, porphyritic texture, inequigranular crystal forms in these rocks are anhedral to subhedral, mineral compositions found megascopically include: plagioclase, pyroxene, hormblend, and a little pyroxene epidote and hormblend present as phenocryst,  and there is a small amount of secondary minerals in the form of epido. In pyroclastic lithofasies, lapilli facies has a characteristic light brown color, grain size (2 mm to 64 mm), the shape of the grain on this patuan is rounded and angled, it is interpreted that the deposition of this rock is some distance from the sembernya based on the size of the rock grain with the mass of the glass volcanic base, silica nin carbonate cement, poor sortation, open packaging, and has been compacted. Volcanic breccia facies have characteristics, among others: the color of light ash, the grain in this rock is gravel to kerakal (block), with angled grain bektuk responsibility until it is round (polymic), can be interpreted that this rock is far enough from the source based on the shape of the grain of the rock, pack it on this rock open container, poor sortation, igneous rock fragments in the form of andesite, non-carbonate silica cement, and glas volcanic matrix. While tuff facies has characteristics, brown color, grain size in this rock is fine, semaen in this rock is carbonate cement, closed packaging, has good sorting, weathered oxide (which is characterized by orange color), this rock has been compacted.

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.
