Mangrove adalah vegetasi yang dijumpai di kawasan pesisir, khususnya di wilayah tropis dan mampu bertahan hidup di bawah lingkungan dengan salinitas yang lebar. Ekosistem mangrove sangat produktif dan memainkan peran penting secara ekologi, ekonomi, dan sosial. Masalah yang dihadapi mengenai konversi lahan serta dampak alam terhadap mangrove dapat dirasakan oleh ekosistem mangrove di wilayah pantai utara Jawa, tidak terkecuali di Desa Pantai Bahagia, Kecamatan Muara Gembong, Kabupaten Bekasi. Tujuan dari penelitian ini adalah untuk mengetahui sebaran vegetasi mangrove, mengetahui luas vegetasi mangrove, dan mengetahui klasifikasi tutupan vegetasi mangrove di Desa Pantai Bahagia dengan menggunakan data citra Sentinel-2A melalui studi pengindraan jauh dan validasi di lapangan. Penelitian ini bersifat deskriptif eksploratif dengan pendekatan pengindraan jauh untuk mengetahui sebaran mangrove menggunakan band composite serta analisis Normalized Difference Vegetation Index (NDVI). Validasi dari analisis spasial dilakukan dengan hemispherical photography dan diuji akurasinya. Hasil dari penelitian ini adalah Mangrove di Desa Pantai Bahagia tersebar di dekat wilayah konservasi hutan lindung, di dekat sepanjang aliran sungai, di dekat wilayah pertambakan, area pantai, dan di dekat wilayah pemukiman. Luas sebaran mangrove di Desa Pantai Bahagia yakni sebesar 464,418 ha. Klasifikasi kerapatan tutupan kanopi mangrove di Desa Pantai Bahagia yakni kerapatan padat dengan luas sebesar 451,91 ha (97%), 5,96 ha (1%) dari total luasan mangrove memiliki kondisi kerapatan kanopi mangrove sedang, dan 6,55 ha (2%) memiliki kondisi kerapatan kanopi jarang. Mangroves are a type of vegetation that grows along the coast, particularly in tropical areas, and can withstand a broad salinity range. The ecosystems of mangroves are very productive and perform an essential ecological, economic, and social role. Mangrove habitats on the northern coast of Java, including Pantai Bahagia Village, Muara Gembong District, Bekasi Regency, are dealing with the effects of land conversion and natural impacts on mangroves. The purpose of this research was to use Sentinel-2A image data to determine the distribution of mangrove vegetation, the extent of mangrove vegetation, and the classification of mangrove vegetation cover in Pantai Bahagia Village through remote sensing studies and field validation. The distribution of mangroves was determined using composite bands and analysis of the Normalized Difference Vegetation Index (NDVI) in this descriptive exploratory study. Hemispherical photography was used to verify the spatial analysis results and the accuracy was measured. Mangroves in Pantai Bahagia Village are distributed around protected forest conservation areas, rivers, fish ponds, coastlines, and residential areas. Pantai Bahagia Village has a mangrove distribution area of 464.418 ha. Pantai Bahagia Village's mangrove canopy cover density is classified as dense with 451.91 ha (97%) of the total mangrove area, 5.96 ha (1%) of the total mangrove area with a medium density of mangrove canopy, and sparse with 6.55 ha (2%) of the total mangrove area.
