Bayu Aji Pratama. 26040118130121. Analisis Distribusi Spasial Kerapatan
Tutupan Mangrove Berdasarkan Citra Satelit Sentinel-2A di Desa Pantai Bahagia,
Muara Gembong, Kabupaten Bekasi (Ibnu Pratikto dan Adi Santoso)
Mangrove adalah vegetasi yang dijumpai di kawasan pesisir, khususnya di
wilayah tropis dan mampu bertahan hidup di bawah lingkungan bersalinitas yang
ekstrem. 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. Dengan menganalisis secara
spasial sebaran, luasan, dan persentase tutupan mangrove di Desa Pantai Bahagia,
hasil yang didapat akan menjadi sebuah landasan dalam pengelolaan mangrove dan
tata guna lahan di Desa Pantai Bahagia.
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.
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%), 6,55 (2%) memiliki kondisi kerapatan kanopi jarang,
dan 5,96 ha (1%) dari total luasan mangrove memiliki kondisi kerapatan kanopi
mangrove sedang.
Kata kunci: Mangrove, Sentinel-2A, NDVI, Fotografi Hemisferikal

SUMMARY
Bayu Aji Pratama. 26040118130121. Spatial Distribution Analysis of Mangrove
Vegetation Cover Utilizing the Sentinel-2A Satellite Imagery in Pantai Bahagia
Village, Muara Gembong, Bekasi Regency (Ibnu Pratikto and Adi Santoso)
Mangroves are a type of vegetation that grows along the coast, particularly
in tropical areas, and can withstand high salinity. Ecosystems of mangroves are
very productive and perform an essential ecological, economic, and social role.
Mangrove habitats in 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 results of spatially
analyzing the distribution, area, and percentage of mangrove cover in Pantai
Bahagia Village can serve as a foundation for mangrove management and land
use in the village.
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.
The mangroves in Pantai Bahagia Village are distributed out 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, sparse with 6.55 ha (2%) of the
total mangrove area, and 5.96 ha (1%) of the total mangrove area with a medium
density of mangrove canopy.
Keywords: Mangrove, Sentinel-2A, NDVI, Hemispherical Photography
