Abstract

Changes in vegetation cover due to urbanization in Cirebon City have a significant impact on land surface temperature and the Urban Heat Island (UHI) phenomenon. This study analyzes vegetation distribution and surface temperature changes from 2018 to 2025 using Landsat 8 imagery with NDVI, LST mapping, and change detection methods. The results indicate that vegetation loss is associated with rising temperatures and the intensification of UHI, while areas with preserved vegetation exhibit lower temperatures. These findings highlight the importance of preserving and expanding green open spaces as a mitigation strategy against land use change impacts and rising urban temperatures.

Abstract

This study aims to identify the characteristics of the Sirnaresmi Village area in supporting food security through the use of Geographic Information Systems (GIS). The method used is descriptive quantitative with spatial analysis of several physical and environmental parameters, including slope, land use, soil type, and lithology. The results show that this village has great potential with fertile volcanic soils such as Andosol and Kambisol, as well as forest areas that function as water buffers and microclimate regulators. Slope variation affects land use patterns and agricultural potential, with the gentle slopes in the center of the village becoming the main area for food commodity development. The use of GIS has proven effective in mapping resource distribution and supporting sustainable development planning, thereby increasing the village's capacity for resource management and food security. All these aspects indicate that with proper management and the use of GIS technology, Sirnaresmi Village has great potential to maintain and improve the community's food security in a sustainable manner, despite facing challenges related to topography and diverse land use.
