Analisis Spasial Perubahan Garis Pantai di Pesisir Kabupaten Lampung Timur Tahun 2018-2023
The coastline is the boundary line between land and sea level. Coastal areas can experience changes, including by ecological and social factors that occur on the coast from time to time. (Guariglia, 2006). Coastlines can be identified using various types of technology, one of which is remote sensing. In this study, Landsat 8 OLI/TIRS satellite imagery was used with data acquisition for 2018-2023, which is a multispectral image used to identify changes in the coastline. Identification of the coastline uses the Green and NIR bands to separate land and sea so that the coastline can be extracted for data processing
Changes in the coastline are related to changes in mangrove area resulting in a very strong correlation from the data that is processed. This research was conducted in East Lampung Regency which is in Labuhan Maringgai District and Pasir Sakti District. The two districts have a large accretion rate. Labuhan Maringgai District experienced a dominance of accretion of shoreline changes from 2018-2023 covering an area of 75.48 ha and has an average coastline change of 19.94 m. The displacement of the accretion coastline in Pasir Sakti District from 2018-2023 with an average shoreline change due to accretion of 129.11 m and an average coastline change and shoreline change due to accretion has an area of 151.28 ha.
Mangrove land changes experienced a very significant increase from 2018-2023, in the Labuhan Maringgai District there was an increase of 79.04 ha and the Pasir Sakti District experienced an increase in mangrove changes of 195.52 ha. Shoreline changes and changes in mangrove land on the coast have a very high relationship. If the shoreline changes increase, then there will be an increase in mangrove area or vice versa.
