SUSTAINABLE DEVELOPMENT OF STRATEGIC ECONOMIC AREA WEST- EAST CORRIDOR WEST SUMATRA BASED ON SERVICE FACILITIES COMPLETENESS INDEX

Regional development is a fundamental change in the socio-economic, cultural, and institutional structure to overcome income inequality and alleviate poverty. Regional development aims to formulate and apply theoretical frameworks into policies and programs by integrating social and environmental aspects to realise optimal and sustainable welfare. Learning the role of strategic areas and regional sustainability is necessary to support complete service facilities. The construction of good service facilities ensures efficiency, facilitates the movement of goods and services and increases the added value of the economy. This study looks at the spatial diversity of the factors that influence the Service Facility Index to develop a sustainable west-east corridor strategic economic area. The method used in this research is the scalogram method and Geographically Weighted Regression, with the unit of analysis being the sub-district. The analysis results show that the spatial pattern of the Service Facility Index based on the investigation of Moran I is random along the west-east corridor. The factors that significantly affect the sustainable development of the west-east corridor are the area’s population and altitude.
