STUDI PERUNTUKKAN LAHAN RUANG TERBUKA HIJAU BERDASARKAN KERAPATAN VEGETASI DAN SUHU PERMUKAAN PERKOTAAN DI KOTA PALU

City is the center of various activities and services. High urban activity can also affect the temperature to become warmer. This causes a temperature difference between the urban area and the area around it which is called the Urban Heat Island (UHI). Palu City is one of the hottest city in Indonesia. And one of the elements that can reduce urban temperatures is green open space. The number of green open spaces in Palu City is currently very low, which is only around 203.66 hectares or only 0.52% of the total area of Palu City. Of course, this is still very much less than the standard for providing green open spaces in urban areas where the availability of green open spaces in urban areas is around 30%. Therefore it is necessary to have research on the location of green open space development based on vegetation density and also urban surface temperature.
The research method used in this research is descriptive quantitative. There are several analysis techniques that researchers use in this study, including Normalized Difference Built-up Index analysis or NDBI, Normalized Difference Vegetations Index analysis or NDVI, Land Surface Temperature analysis and overlay analysis.
The results of this research indicate that land allotment for green open spaces in the Palu Urban Area is spread across all Districts in Palu Urban. The total area of the land allotment for this green open space is 6,359.85 hectares. The type of green open space to be built must adapt to site conditions.
