Analisis Perubahan Garis Pantai pada Kawasan Pesisir Kabupaten Deli Serdang

Abstract

The coastal region of Deli Serdang Regency encompasses 4 sub-districts, namely Labuhan Deli Sub-district, Hamparan Perak Sub-district, Percutseituan Sub-district, and Pantai Labu Sub-district. This research aims to analyze changes in the coastline and vegetation density in the coastal area of Deli Serdang Regency. The method used in this research is overlaying the coastline from Landsat 8 OLI satellite imagery data in 2013 and Sentinel 2 satellite imagery data in 2017 and 2022, as well as vegetation density classification using three density classes: sparse, moderate, and dense. This research shows changes in the coastline from 2013 to 2017, with 52.54 Ha of erosion and 44.63 Ha of accretion. From 2017 to 2022, erosion is 49.38 Ha, and accretion is 52.54 Ha. Overall, from 2013 to 2022, erosion is 46.50 Ha, and accretion is 156.69 Ha. The widest vegetation density was in the "Medium" density class in 2013 with an area of 1679.45 ha or 74.47% of the total area of the coastal border area in the coastal area of Deli Serdang Regency. The smallest vegetation density area was the "Meeting" density class in 2013 with an area of 203.11 ha or 4.57% of the total area. Changes in the area of one vegetation density class affect the area of other vegetation density, so that a decrease in one class can cause an increase in other density classes.
