Mangrove merupakan vegetasi yang akarnya menjalar dipermukaan, dan berada di muara sungai, dan pesisir. Hutan mangrove sangat penting keberadaannya karena merupakan sistem di dalam menyeimbangkan ekosistem di pesisir, dan muara sungai. Deforestasi hutan mangrove dari akibat alih fungsi lahan pada vegetasi mangrove menjadi ancaman bagi keberlanjutan kehidupan di wilayah pesisir, dan muara. Keberadaan vegetasi mangrove yang penting bagi Kabupaten Belitung Timur untuk menjaga dari abrasi, dan habitat satwa. Aktivitas manusia menyebabkan alih fungsinya hutan mangrove sehingga menimbulkan deforestasi. Aktivitas manusia menyebabkan alih fungsi berbentuk aktivitas pertambangan, dan budidaya tambak udang. Luasan hutan mangrove yang semakin berkurang dari aktivitas tersebut menyebabkan deforestasi. Hal ini akan menjadi ancaman kepunahan yang akan terjadi di masa depan. Monitoring mangrove sangat penting karena untuk melihat deforestasi luasan hutan mangrove yang berubah dari tahun 2017 ke tahun 2024. Data Sentinel 2 sangat berperan penting untuk data yang diolah untuk melihat keberadaan, dan luasan alih fungsi. Dengan menggunakan rumus Mangrove Vegetation Index (MVI) untuk mengetahui area vegetasi mangrove. Pengolahan data menggunakan cara Random Forest untuk menganalisis tingkat lanjut terhadap perubahan alih fungsi mangrove. Sehingga memudahkan dalam pemetaan terjadinya alih fungsi mangrove. Dilakukan juga survei lapangan (ground check) untuk validasi pada Area of Interest (AOI) yang dikaji.References
