(Ghifar Naufal Aslam. 260 401 191 301 23. Stuktur dan Komposisi Serta Tutupan Kanopi Mangrove di Kawasan Lembur Mangrove Patikang, Desa Citeureup, Kabupaten Pandeglang, Provinsi Banten. Rudhi Pribadi dan Ambariyanto).
Ekosistem mangrove merupakan komunitas tumbuhan yang mempunyai kemampuan adaptasi yang baik pada perairan air asin di wilayah intertidal dan tumbuh hidupnya dipengaruhi oleh pasang surut air laut. Mangrove di Desa Citeureup, Kecamatan Panimbang, Kabupaten Pandeglang merupakan kawasan mangrove yang berada di pesisir barat Pulau Jawa. Tujuan penelitian ini yaitu untuk mengkaji struktur dan komposisi serta tutupan kanopi vegetasi mangrove di Kawasan Lembur Mangrove Patikang. Penelitian ini dilakukan untuk upaya pelestarian dan perlindungan mangrove yang berada di Desa Citeureup. Maka dari itu perlu didapatkan informasi untuk pembuatan kebijakan pengelolaan mangrove yang berkelanjutan dengan pendekatan analisis vegetasi mangrove. Penelitian ini dilaksanakan pada bulan Mei 2022. Pengambilan sampel dilakukan di Kawasan Lembur Mangrove Patikang, dengan 6 stasiun. Pengambilan data vegetasi dilakukan dengan metode survei dan setiap stasiun dibuat plot transek. Setiap individu pohon dan anakan (plot 10 m x 10 m) diidentifikasi spesies berdasarkan buku identifikasi mangrove dan diukur diameternya setinggi dada atau Diameter at Breast High (DBH ± 1,3 m). Sementara itu untuk kategori semai dihitung jumlah masing-masing spesiesnya. Tutupan kanopi vegetasi mangrove dianalisis menggunakan metode Hemispherical Photography. Persentase tutupan kanopi dapat dianalisis menggunakan software ImageJ untuk menghitung dua kontras warna putih menunjukkan langit dan hitam menunjukkan kanopi mangrove. Hasil penelitian di Kawasan Lembur Mangrove Patikang ditemukan tiga spesies mangrove didalam plot. Vegetasi mangrove di lokasi penelitian memiliki kerapatan yang berkisar 867 – 1933 ind/ha. Indeks Keanekaragaman (H’) dan Keseragaman (J’) kategori pohon termasuk dalam kategori rendah. Hasil persentase tutupan kanopi mangrove yang didapatkan memiliki nilai rata-rata persentase tutupan sebesar 78,5 ± 1,65% sehingga dapat disimpulkan lokasi penelitian ini termasuk kategori baik (padat).
Kata Kunci: Mangrove, Kerapatan, Hemispherical Photography.

ABSTRACT
(Ghifar Naufal Aslam, 260 401 191 301 23. Structure and Composition and Canopy Cover of Mangroves in Patikang Mangrove Valley Area, Citeureup Village, Pandeglang Regency, Banten Province. Rudhi Pribadi and Ambariyanto).
Mangrove ecosystems are plant communities that have good adaptability to salt water in intertidal areas and their growth is influenced by tides. Mangroves in Citeureup Village, Panimbang District, Pandeglang Regency is a mangrove area located on the west coast of Java Island. The purpose of this study was to assess the structure and composition and canopy cover of mangrove vegetation in the Patikang Mangrove Area. This research was conducted for the preservation and protection of mangroves in Citeureup Village. Therefore, it is necessary to obtain information for making sustainable mangrove management policies with a mangrove vegetation analysis approach. This research was conducted in May 2022. Sampling was conducted in the Patikang Mangrove Area, with 6 stations. Vegetation data collection is done by survey method and each station is made transect plot. Each individual tree and sapling (plot 10 m x 10 m) identified species based on mangrove identification book and measured its Diameter at Breast Height (DBH ± 1.3 m). Meanwhile, for the seedling category, the number of each species was counted. Canopy cover of mangrove vegetation was analyzed using the Hemispherical Photography method. The percentage of canopy cover can be analyzed using ImageJ software to calculate the two color contrasts white indicates the sky and black indicates mangrove canopy. The results of research in the Patikang Mangrove Valley Area found three mangrove species in the plot. Mangrove vegetation in the study site has a density that ranges from 867 - 1933 ind/ha. Diversity Index (H') and Uniformity (J') tree category is included in the low category. The results of the percentage of mangrove canopy cover obtained have an average percentage cover value of 78.5 ± 1.65% so that it can be concluded that this research location is in the good (dense) category.
Keywords: Mangrove, Density, Hemispherical Photography.
