Abstract : Sayung District, which is located in the Demak Regency of Central Java Province, has been experiencing the shorelines and land use changes due to erosion and sedimentation process. The present study aims to analyze the changes that occurred during the periods of 2007-2011 and 2011-2017, to study the differences in shorelines due to erosion and sedimentation, and how the changes in coastline affect the landuse. The image data used was obtained from Landsat 5 and Landsat 8. The method of processing image data included a geometric correction, radiometric correction, cropping, digitation on-screen and image classification—spatial data analysis using the overlay method. Field observations were carried out in July-August 2017 in the coastal area of Sayung District. The results of the study show that the area of erosion changed from 365.64 ha in 2007-2011 to 359.01 ha in 2011-2017 and the area of sedimentation changed from 14.82 ha in 2007-2011 to 56.32 ha in 2011-2017. Based on the image classification, Sayung is composed of eight types of land uses: inundation, industries, dry land, sea, mangroves, settlements, ponds, and land vegetation. The most significant land-use change during 2007-2011 occurred in the settlement land. From the initially 1103.85 ha, 339.84 ha of the settlement land became inundated land. During 2011-2017, 435.13 ha of the originally inundated land turned into fishponds. The present study concludes that the change in shorelines in Sayung District is in line with the change in landuse.
