KLASIFIKASI LUASAN EKOSISTEM MANGROVE DI DESA PANTAI BAHAGIA, MUARA GEMBONG, KABUPATEN BEKASI DENGAN CITRA SENTINEL DENGAN METODE NORMALIZED DIFFERENCE VEGETATION INDEX | CLASSIFICATION OF MANGROVE ECOSYSTEM AREA IN PANTAI BAHAGIA VILLAGE, MUARA GEMBONG, BEKASI REGENCY, USING SENTINEL IMAGERY WITH NORMALIZED DIFFERENCE VEGETATION INDEX METHOD

English. Mangrove ecosystems are one type of coastal resources that has benefits in physical, biological, and economic wise. Mangrove ecosystems in Muara Gembong are ecosystems that are included in the category of protected forest. This research aims to estimate the area of mangrove forests and classify its canopy cover. The method used in this study is the Normalized Difference Vegetation Index (NDVI) and using sentinel imagery (with a spatial resolution of 10 m). The canopy cover classification applied in this study refers to the Indonesian Ministry of Forestry standards. Canopy cover data was validated with a densiometer to estimate the percentage of mangrove canopy cover. The results showed that the area of mangrove forests reached 301.83 ha with a high-density level or a tight cover class reaching 59.31% or 179.02 ha. The area of mangroves in Pantai Bahagia Village, Bekasi Regency, has increased from the last few years due to rehabilitation actions taken by several local communities.

Indonesian. Ekosistem mangrove merupakan salah satu jenis sumber daya pesisir yang mempunyai manfaat baik secara fisik, biologis, dan ekonomis. Ekosistem mangrove di Kecamatan Muara Gembong merupakan ekosistem yang termasuk dalam kategori hutan lindung. Penelitian bertujuan mengestimasi luas hutan mangrove dan mengklasifikasi tutupan kanopi. Metode yang digunakan adalah Normalized Difference Vegetation Index (NDVI) dan menggunakan citra sentinel (resolusi spasial 10 m). Klasifikasi tutupan kanopi mengacu pada standar Departemen Kehutanan Republik Indonesia. Data tutupan kanopi divalidasi dengan densiometer yang melihat persen tutupan kanopi mangrove. Hasil menunjukkan luas hutan mangrove mencapai 301,83 ha dengan tingkat kerapatan tinggi atau kelas tutupan rapat (dense) mencapai 59,31% atau 179,02 ha. Luasan mangrove di Desa Pantai Bahagia, Bekasi, meningkat dari beberapa tahun terakhir oleh karena adanya usaha rehabilitasi oleh komunitas lokal.
