Abstract

This research focuses on understanding the characteristics of the Urban Heat Island (UHI) phenomenon in Parepare City, Indonesia, and its relationship with vegetation density and land surface temperature. The study utilizes satellite imagery data from 2014 and 2021 to analyze the spatial distribution of land surface temperature and vegetation density. The results show a significant negative correlation between vegetation density and land surface temperature, indicating that an increase in vegetation density can contribute to lowering the land surface temperature and mitigating the UHI effect. The findings also emphasize the importance of green open spaces in maintaining a balance of vegetation and preventing a drastic increase in UHI. However, challenges such as land conversion and high population density in the city center pose threats to vegetation preservation. Sustainable land management practices and urban greening initiatives need to be implemented to address these issues. The research concludes that by prioritizing these measures, Parepare City can effectively mitigate the UHI effect and enhance the urban environment's quality and livability.

Abstract

Sea surface temperature (SST) is a key parameter in the study of marine ecosystems, which plays an important role in determining the biological and physical dynamics of waters. This study analyzes changes in sea surface temperature in Saugi Island and its impact on coastal ecosystems. Using spatial analysis methods through remote sensing using Aqua Modis satellite imagery, sea surface temperature data were collected from August to September 2024. The results show that sea surface temperatures vary between 30°C and 36°C, with an average reaching 31.3°C. This increase in temperature has the potential to affect the metabolism and reproduction of marine organisms, as well as worsen the condition of coastal ecosystems due to seawater acidification and salinity fluctuations. This study aims to provide insight into the dynamics of sea temperature changes and the need for mitigation measures to protect ecosystems and improve the sustainability of coastal communities. This study is expected to be the basis for developing strategies in dealing with changes in sea surface temperature that have an impact on coastal ecosystems with mitigation efforts of the temperature monitoring network and eco wave initiative.
