Abstract

Urban Heat Island (UHI) adalah sebuah fenomena lingkungan di mana suhu (misalnya bangunan, beton, aspal dan aktivitas industri) di daerah perkotaan secara signifikan lebih tinggi daripada di daerah pedesaan di dekatnya. Banyak bukti telah membuktikan bahwa itu dapat menyebabkan beberapa efek buruk bagi masyarakat, seperti peningkatan konsumsi energi. Suhu permukaan tanah (LST) diambil dari tiga perekaman data Landsat multitemporal untuk menganalisis pola spasial termal dan intensitas permukaan. UHI tidak dapat diketahui hanya melalui pemrosesan citra tanpa mengidentifikasinya dan analisa spasial melalui Sistem Informasi Geografis (SIG), proses penelitian ini ditandai dengan mengkonversi digital number pada citra satelit Landsat 7ETM+ dan Landsat 8 OLI/TIRS pada Band Thermal untuk menghasilkan LST, proses selanjutnya dilakukan di lingkungan perangkat lunak SIG untuk memperoleh sebaran UHI. Hasil analisa sebaran suhu permukaan daratan (LST) menunjukkan bahwa suhu maksimum kota padang tahun 2007 hingga 2013, terjadi kenaikan nilai suhu maksimum daratan kota padang sebesar 3.840C. Sedangkan untuk tahun 2013 hingga 2017 terjadi kenaikan suhu permukaan daratan 1.570C. Sementara itu untuk sebaran UHI kota padang pada periode pengamatan mengalami peningkatan yang signifikan, terdistribusi hampir keseluruh wilayah pinggiran kota dengan luas awal tahun 2007 yakni 31, 37 Ha menjadi 8.754,60 Ha pada tahun 2017.Kata kunci: Landsat, LST, UHI

Abstract

The movement of the Sumatran fault is triggered by plate activity in the western subduction zone of Sumatra, namely the Indo-Australian plate which moves down the Eurasian plate, causing pressure to push the Sumatra region towards the north. The purpose of this study is for the results of Ascending and Descending data on the impact of faults that occur on the Semangko Segment Sianok fault from 2020-2023 and to map the Land Displacement of the Semangko Segment Sianok fault from 2020-2023. Based on the results of data processing in this study, it can be concluded that in this study using ascending and descending direction data that experienced land movement (Land Displacement) due to this movement the impact of faults that occurred due to seismic activity along the segment resulted in the impact of natural disasters such as landslides, and earthquakes. This impact was triggered due to land movement because the effects of surface faults and ground shaking did cause most of the damage in several events. The ascending data explains the annual uplift of 15.28 mm marked in dark blue and the red color on the map shows the subsidence of -30.55 mm per year, while the light bitu color dominates in urban areas or areas inhabited by many people. While in the descending data, changes in land movement show an annual uplift of 6.74 mm and the red color shows subsidence of -13.47 mm per year. From the color change of each data shows ascending and descending data experiencing land subsidence uplift and subsidence.

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

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.

Abstract

Rapid urban development in Bukittinggi City has altered vegetation cover, built-up density, and surface thermal conditions. This study maps and compares the Normalized Difference Vegetation Index (NDVI), Land Surface Temperature (LST), Normalized Difference Built-up Index (NDBI), and Urban Heat Island (UHI) in 2015 and 2025 and examines the relationships of NDVI and NDBI with UHI. Quantitative descriptive spatial analysis used Landsat 8 OLI/TIRS imagery processed in ENVI and ArcGIS. NDBI classification accuracy was assessed using ROC-AUC, while relationships were evaluated with Pearson correlation and simple regression. Very low vegetation increased from 621.54 to 707.31 ha, while medium vegetation decreased from 538.65 to 451.44 ha. Maximum LST rose from 28.45°C to 31.24°C. Medium built-up land increased from 611.01 to 691.29 ha. Non-UHI area decreased from 598.14 to 461.07 ha, whereas high-intensity UHI expanded from 521.82 to 588.51 ha. The NDBI map achieved an AUC of 0.811, indicating very good classification performance. NDBI showed the strongest positive relationship with UHI, while NDVI showed a weak negative relationship. LST was analyzed descriptively because UHI was derived directly from LST. These findings emphasize the importance of controlling the concentration of built-up surfaces and maintaining urban vegetation.
