Analisis Abrasi Pantai Dan Degradasi Hutan Mangrove Pulau Rangsang Menggunakan Google Earth Engine (Gee)

---

ABSTRACT
Mangrove forests typically grow along coastlines and play a crucial role in
protecting coastal areas from sea water-induced abrasion. Rangsang Island is
located in a coastal region directly facing the Malacca Strait, making it vulnerable
to coastal abrasion and shoreline changes. Google Earth Engine (GEE) is a
platform that facilitates research related to shoreline changes caused by abrasion,
which in turn affects mangrove forest degradation. This study aims to spatially and
temporally analyze shoreline changes and mangrove forest degradation on
Rangsang Island, as well as to examine the correlation between coastal abrasion
and mangrove degradation. A quantitative descriptive method was employed,
utilizing ArcGIS 10.8 software for overlay analysis and spatial quantification to
determine the extent of coastal abrasion between 1994 and 2024 at two-year
intervals. In addition, a reclassification analysis of mangrove density was
conducted to estimate the extent of mangrove degradation during the same period.
Secondary data used in this study include satellite imagery from Landsat 5, 7, and
8, as well as administrative boundary and area data of villages on Rangsang Island.
The results show that Rangsang Island experienced coastal abrasion amounting to
1.532,06 hectares from 1994 to 2024, with the northern coast eroding at a rate of
98.78 ha/year and the southern coast at 41,21 ha/year. Furthermore, mangrove
forests degraded from an initial total area of 15.879,98 ha in 1994 to 9.132.61 ha
in 2024. This research is expected to contribute to efforts to mitigate coastal
abrasion on Rangsang Island and to enhance the protection of mangrove forests in
order to prevent further environmental degradation.
Keywords: Abrasion, Mangrove Degradation, Overlay, Reclassify, Google Earth
