Protected area development examination based on land use curve number value changes in Nusantara National Capital Region

Abstract

Abstract This study examines the impact of land use changes on the intended extent of protected areas in the Nusantara National Capital Region (IKN). This study’s land use changes result from land use projections based on the IKN’s spatial plan (RTRW IKN) and land use projections considering the potential flood inundation areas for the Q100 recurrence interval, as determined by Clue analysis. Regression analysis with SPSS is used to determine the relationship between one or more independent variables (predictors) and a dependent variable (response variable) to analyze the mathematical equation used to calculate the size of protected areas. The analysis results reveal alterations in the size of protected areas within a watershed due to variations in the Curve Number (CN) values. A more excellent CN value reduces the extent of protected areas in a watershed and vice versa. This study is anticipated to provide helpful information for spatial planning decisions in the IKN, particularly in the Government Core Centre (KIPP) region.
