Spatial Analysis of LULC Changes and Suitability of Ngawi Regency on Spatial Regional Planning 2011-2031 Using Geographic Information System

Abstract

Abstract This study analyzes land use change in Ngawi Regency, East Java, in 2011 and 2021 and examines the suitability of land use, Regional Spatial Plan, and Regional Medium-Term Development Plan. Qualitative descriptive analysis methods and spatial-temporal analysis are used to identify land-use change, land-use change, and land-use-related problems. The results showed a discrepancy between actual land use and RTRW in several sub-districts, such as Padas, Pangkur, Ngawi, Pitu, Kedunggalar, Ngrambe, Sine, Jogorogo, Kendal. This discrepancy includes changes in land functions from settlements to industries, tourism areas to settlements, industries to settlements, and vice versa. The total area of nonconformity reached 40,361 hectares or 28.93 % of the Ngawi area. GIS and map overlays provide an in-depth understanding of land change patterns, with settlements and industrial sectors being key focuses. Although the Regional Spatial Plan has been established to regulate land use, its implementation still needs to be improved in 2021. The development of tourism, industrial, agricultural, and residential areas sometimes goes differently than planned. This research highlights the need for coordination between Regional Medium-Term Development Plans and Regional Spatial Plans to achieve sustainable regional development.
