Utilization of SAR Data to Evaluate Industrial Locations on the North Coast of Central Java

Abstract Central Java province, located on the northern coast of Java Island, holds a strategic position as a busy land transportation route, connecting cities in southern Central Java and East Java with the capital city. The growth of industrial centers and industrial zones along the northern coast of Central Java is a positive effect of this position. However, the subsidence of land along the northern coast of Central Java is its negative impact. This can be detrimental to industrial areas and settlements along the northern coast of Central Java. Therefore, spatial planning must consider this land subsidence. The utilization of SAR data to periodically monitor land subsidence is crucial in formulating spatial arrangements that can accommodate the impact of land subsidence. In this study, to obtain land subsidence, the InSAR method was used. The data processed in this study consisted of Sentinel 1 from 2015 – 2023. It was found that land subsidence in the coastal areas of northern Central Java ranges from 0 to 25 cm per year. This data on land subsidence serves as an important basis for policymakers, planners, and stakeholders to develop more effective adaptation and mitigation strategies in spatial planning in the coastal areas of northern Central Java.
