Abstract

This study examines the relationship between land cover change and surface temperature increase in Mataram City using remote sensing and quantitative analysis. As urban areas continue to grow due to population increase and development needs, land conversion—especially from vegetated land to built-up areas—has become inevitable. This study aims to analyze the extent of land cover change over a 10-year period (2013–2023) and assess its impact on land surface temperature (LST). Landsat 8 imagery was utilized to extract Normalized Difference Vegetation Index (NDVI) and calculate LST using Band 10 and Band 11. The results show a significant increase in built-up land by 1,325.35 hectares and a decrease in vegetated land by 1,122.34 hectares. The average surface temperature increased by 2.25°C, with a minimum of 25°C and a maximum of 35°C in 2023. A simple linear regression analysis was conducted to determine the influence of land cover change on LST. The analysis revealed a strong correlation, with an R-square value of 0.845, indicating that 84.5% of the increase in surface temperature is influenced by changes in land cover. These findings highlight the ecological consequences of urban expansion and underscore the importance of maintaining green spaces to mitigate urban heat effects. This research contributes to the field of geography education by demonstrating how geospatial tools can be used to understand urban environmental issues.
