Abstract
Terumbu karang merupakan ekosistem penting di Perairan Pulau Kelapa Dua yang seiring waktu mengalami perubahan karena beberapa faktor yang mempengaruhi. Upaya monitoring memanfaatkan penginderaan jauh dengan menggunakan Citra Satelit Sentinel guna melihat perubahan terumbu karang pada tahun 2015, 2019, dan 2023. Penelitian ini bertujuan untuk menganalisis kemampuan citra satelit dalam memetakan terumbu karang menggunakan algoritma Lyzenga dan unsupervised classification dan menganalisis perubahan luasan terumbu karang yang terjadi di Pulau Kelapa Dua pada kurun waktu 9 tahun. Hasil identifikasi menggunakan Lyzenga dan unsupervised classification pada Pulau Kelapa Dua dikategorikan pada 4 kelas yaitu terumbu karang, pasir, alga, dan lamun. Nilai akurasi terbaik diperoleh dari input Composite Band 2/3, 2/4, 3/4 dengan nilai 92,19%. Perubahan terumbu karang pada tahun 2015-2023 berkurang sebesar 20.294 m^2, pasir berkurang 44.230 m^2, alga bertambah 169.516 m^2, dan lamun berkurang 104.921 m^2.
