Abstract

Changes in land surface temperature are one of the important indicators in monitoring global environmental change. In the last decade, increasing surface temperatures have become a global concern, as they have the potential to affect ecosystems, air quality, water availability and human health. In addition, increasing land surface temperature also has a direct impact on the urban heat island phenomenon, which can worsen environmental conditions in urban areas. In this context, analyzing periodic changes in land surface temperature is important to understand the patterns and factors that influence these changes. The objectives in conducting this research, namely: Analyzing the land surface temperature, Creating a regional land surface temperature map and Analyzing changes in land surface temperature from the land surface temperature map of Pariaman City in 2015, 2019, and 2023. Based on the results of the analysis of changes in land surface temperature using Landsat 8 OLI/TIRS images in 2015, 2019, and 2023, it was found that there were significant variations in temperature changes in several areas. Landsat 8 image data is processed through several stages, starting from converting Digital Number (DN) values to spectral radians, brightness temperature, to estimating Land Surface Temperature (LST) in Celsius units. The analysis shows that there was a significant increase in land surface temperature during the period, especially in urban and coastal areas. In 2015, the majority of areas had temperatures of 20°C-24°C, while in 2019 it shifted to 24°C-28°C, and in 2023 it was dominated by temperatures of 28°C-32°C and above 32°C. These changes reflect a significant local warming trend, influenced by human activities and land use change. This research is expected to contribute to the understanding of environmental dynamics and support spatial planning that is more adaptive to climate change.

Abstract

Padang-Solok Road, which has uphill road conditions and sharp corners, makes this road a lot of accidents. Apart from the negligence of motorists, accidents in this area are also caused by geometric factors of the road. The purpose of this study is to determine the suitability or not of road geometry in terms of horizontal alignment with the Highways method. This type of research is descriptive quantitative. It was found thatthe existence of the existing situation after being concluded from the approach of the experience of going into the field is that the road has a fairly extreme slope where the road on the left if it leads to Solok has a fairly high slope. And the existing suitability with clan building has several differences, discrepancies and gaps both intentional due to road conditions and elements of accident.

Abstract

Class C sand mining activities in Nagari Aia Dingin, Lembah Gumanti District, Solok Regency have been ongoing since 1999 and continue to expand to this day. This mining provides economic contributions to the local community, but on the other hand, it also has a significant impact on the environment, particularly on land cover changes. This study aims to analyze changes in open land caused by sand mining activities, using remote sensing technology as a monitoring tool. The approach used is descriptive quantitative, through the interpretation of Google Earth satellite imagery in 2015 and 2018 and Sentinel-2 imagery in 2024. Spatial analysis was conducted with the help of ArcGIS software to obtain a visual and numerical picture of land cover changes. The results of the study indicate a significant increase in the area of sand mining from 2015 to 2024. In 2015, the mining area was recorded at 8.72 hectares, and increased to 22.14 hectares in 2024. This indicates an increase in mining land area of 13.42 hectares over a nine-year period. Land use conversion has occurred on a massive scale, from dryland forest, scrubland, and dryland areas to open-pit mining areas. This land cover change has the potential to cause environmental degradation such as erosion, reduced biodiversity, and disruption to regional water systems. These findings underscore the importance of stricter monitoring and sustainable spatial planning in natural resource management. The use of remote sensing technology has proven effective in monitoring the dynamics of land use change and can serve as a basis for formulating environmental policies that are more responsive to the impacts of mining activities.

Abstract

Business expansion is a strategic step undertaken by companies to increase profitability while broadening their market reach. Hoka Hoka Bento (HokBen) is one of the companies that consistently implements this strategy. This study aims to identify potential locations for new HokBen outlets in Depok City by utilizing Geographic Information Systems (GIS) and spatial analysis. Several parameters were considered, including proximity to commercial and entertainment centers, competitors, educational facilities, public facilities, road networks, population density, banking services, hotels, offices, residential areas, hospitals, existing stores, and places of worship. The analysis was conducted using Euclidean Distance, Buffering, Reclassification, and the Analytical Hierarchy Process (AHP) to determine the priority weights of each criterion. These weights were then integrated through the Weighted Overlay technique to produce a location suitability map. The findings reveal that the most influential factors are commercial and entertainment buildings (0.101), road networks (0.099), and educational facilities (0.092). The resulting suitability map highlights potential areas across Depok City, particularly in zones close to community activity centers. The results demonstrate that GIS-based multicriteria analysis is effective for mapping location suitability and identifying strategic zones for expansion. Therefore, this research contributes to supporting the company’s strategic decision-making through data-driven approaches while also enriching the academic field of business geography and urban planning. In addition, the outcomes can be applied as a reference model for other fast-food chains or retail industries planning spatially optimized expansion strategies in highly competitive urban environments.
