<![CDATA[The rapid conversion of agricultural land into residential areas presents a significant challenge to sustainable regional planning, particularly in areas experiencing population growth and urban expansion. This study aims to develop a GIS-based sustainable regional planning model for predicting agricultural land conversion into residential areas in Klambir Lima Village, Deli Serdang Regency, Indonesia. The study integrates Geographic Information System (GIS) technology with spatial analysis to identify land-use changes and determine areas with high potential for future conversion. Spatial variables include land-use history, distance to roads, distance to residential areas, population density, accessibility, and proximity to public facilities. Historical spatial data are processed through GIS to identify patterns of agricultural land conversion, while predictive analysis is applied to estimate potential future changes. The resulting spatial model generates a land-conversion risk map that can be used to identify agricultural areas requiring protection and areas potentially suitable for residential development. The proposed model provides a data-driven approach for supporting sustainable regional planning by integrating spatial information, land-use prediction, and development considerations. The study is expected to contribute to more effective agricultural land protection, controlled residential expansion, and evidence-based regional planning in Deli Serdang Regency.]]>
