Abstract

Population growth increase every year in the city of Palu has an impact on the increasingly massive development that occurs. While on the other hand, according to PP no 15 of 2010 green open space must be available in a city by 30%, With proportion 20% is public and 10% is private property. In 2018, liquefaction and earthquake were destroyed some part of Palu which caused changes that affected the area of green open space in the city of Palu. Knowing the condition of green open spaces in Palu City is important in order to formulate the best management actions are appropriate for existing conditions. The objective of this research is to determine green open space change from 2018 to 2022 using sentinel 2 satellite imagery. The study site of this research was located in Palu City, focused on other land use or non-forest area. Data used in this research was Sentinel 2 acquired in 2018 represented before liquefaction and 2022 represented the newest condition of the imagery. The method used in this research was post comparison classification (PCC) using the vegetation index difference by utilizing the NDVI (Normalized Difference Vegetation Index) vegetation index. NDVI is the index that sensitive to vegetation or chlorophyll. This research shown that the green open space in 2018 was 61% and decrease in 2022 (62%). In detail, 54% no change of vegetation to vegetation, 31% no change of open area to open area. Vegetation decrease from vegetation to open area were around 7% and vegetation increase 5% from open area to vegetation include liquefaction area around 180ha. The largest decrease in vegetation of 786 ha and the largest increase in vegetation of 624 ha were in Matikulore sub-district, equivalent to 0.17. Smallest change located in tawaeli than other sub-district.
