“…Another study showed stable mangrove coverage in the most extensive urban area, Tual City in Kei islands, from 1999 to 2019 through satellite imagery analysis (Suyadi et al 2021). Excellent mangrove conditions were also identified in a nearby archipelago in Moluccas Province, in particular Sula Islands, by previous studies based on forest canopy coverage assessments (Akbar et al 2016;Baksir et al 2018). Overall, archipelagic mangroves, especially in eastern Indonesia, were commonly in more health conditions due to a lack of anthropogenic threats compared to the western region (Ilman et al 2016).…”

Abstract. Dharmawan IWE, Renyaan J, Nurdiansah D. 2022. Mangrove zonation, community structure and healthiness in Kei Islands, Maluku, Indonesia. Biodiversitas 23: 4918-4927. Forest structure and quality were studied in an archipelagic site in Indonesia which consists of estuarine and oceanic mangrove habitats. This study aimed to determine mangrove structure and estimate the spatial distribution of forest healthiness along the zones dominated by different genera. Forest zones were investigated using the Random Forest method utilizing a cloud-free Harmonized Sentinel-2A-Surface Reflectance image. Community structure measurement followed a stratified purposive sampling design along forest zonation. A spatial-based mangrove health index (MHI) model was applied to analyze forest healthiness distribution in each zone. Mangrove area was clearly classified into six genera-dominated zones such as Sonneratia, Rhizophora, Bruguiera, Ceriops, Xylocarpus and Lumnitzera from seaward to landward. The Rhizophora zone had the most extensive area proportion at approximately 68% of the total mangrove area. This study revealed that S. alba species dominated in the outmost zone at about 200% of IVI, while X. granatum and C. tagal were calculated in a larger IVI value in the more landward area. On the other hand, R. stylosa had a majority species composition in Rhizophora forest. According to spatial analysis of MHI, most zones had a majority area of excellent condition, emphasizing that the entire mangrove forest was pristine.

Ekosistem mangrove merupakan kawasan produktif di daerah pesisir pantai yang dipengaruhi oleh adanya pasang surut dan memiliki keanekaragaman hayati tinggi termasuk mikroba. Sumber karbon organik yang ada pada sedimen mangrove berasal dari detritus makhluk hidup baik hewan maupun tumbuhan dan adanya aktivitas antropogenik. Bakteri pada sedimen mangrove membantu dalam transfer bahan organik pada proses dekomposisi serasah mangrove. Penelitian ini bertujuan untuk mengetahui kelimpahan bakteri dan jumlah isolat bakteri yang didapatkan dari isolasi bakteri sedimen ekosistem mangrove Pantai Tirang, Semarang. Penelitian dilaksanakan pada bulan Desember 2022 - Maret 2023. Metode yang digunakan yaitu deskriptif eksploratif dan metode pengambilan sampel yang digunakan adalah purposive sampling. Sampel sedimen mangrove diambil pada 3 stasiun yang berada di dekat pemukiman, dekat tambak dan dekat dengaurnian muara. Hasil kelimpahan bakteri tertinggi terdapat pada stasiun dekat pemukiman sebesar 4,3 x 104 CFU/mL dan kelimpahan terendah pada stasiun dekat tambak sebesar 8,9 x 103 CFU/mL. Hasil isolasi bakteri didapatkan sebanyak 32 isolat bakteri, dimana pada stasiun dekat pemukiman didapatkan sebanyak 14 isolat, stasiun dekat tambak sebanyak 8 isolat, dan stasiun dekat muara sebanyak 10 isolat dengan karakteristik morfologi yang berbeda.

(Baksir et al, 2018) yang menjadi habitat bagi berbagai organisme laut (Saleky and Merly, 2021;Syahrial et al, 2018) dengan tingkat produktifitas yang tinggi (Dharmawan and Widyastuti, 2017). Selain bagi organisme, ekosistem mangrove juga memberikan manfaat penting bagi manusia (Carugati et al, 2018).…”

Mangrove ecosystem is an important ecosystem in coastal areas which is a habitat for various types of organisms. The existence of mangrove ecosystems in nature is strongly influenced by the availability of mangrove seedlings and seedlings because they are closely related to the secondary succession process in natural habitats. This research was conducted to analyze the potential for regeneration of mangrove seedlings in the coastal area of Dafi Village, Biak Numfor Regency, Papua. Data collection on the potential for regeneration of mangrove seedlings was carried out using the belt transect method. Analysis of species composition and structure of mangrove vegetation at the seedling level used analysis of species density, relative density, species frequency, relative frequency, and important value index. A total of seven mangrove species were found in the coastal area of Dafi Village, Biak Numfor Regency, consisting of Bruguiera gymnorrhiza, Bruguiera cylindrica, Ceriops Tagal, Rhizophora apiculata, Rhizophora mucronata, Rhizophora Stylosa, and Lumnitzera racemoza. The highest species density and relative density values were found in Bruguiera gymnorrizha and Cerops tagal, while the lowest was Rhizophora mucronata and Lumnitzera racemoza. The highest value of species frequency and relative frequency was Bruguiera gymnorrizha, while the lowest was Rhizophora mucronata. The highest Importance Value Index (INP) of mangrove seedlings was found in Ceriops tagal and Bruguiera gymnorrizha, while Rhizophora mucronata had the lowest INP compared to other species.Keywords: Mangrove Ecosystem; Mangrove Regeneration; Important Value Index AbstrakEkosistem mangrove merupakan ekosistem penting di wilayah pesisir yang menjadi habitat bagi berbagai jenis organisme. Keberadaan ekosistem mangrove dialam sangat dipengaruhi oleh ketersediaan anakan dan semai mangrove, karena sangat berkaitan erat dengan proses suksesi sekunder pada habitat alami. Penelitian ini dilakukan dengan tujuan menganalisis potensi regenerasi semai mangrove di Pesisir Kampung Dafi Kabupaten Biak Numfor Papua. Pengumpulan data potensi regenerasi semai mangrove dilakukan dengan menggunakan metode belt transek. Analisis komposisi jenis dan struktur vegetasi mangrove tingkat semai menggunakan analisis kerapatan jenis, kerapatan relatif, frekuensi jenis, frekuensi relatif, dan indeks nilai penting. Total tujuh jenis mangrove ditemukan di Pesisir Kampung Dafi Kabupaten Biak Numfor yang terdiri atas jenis Bruguiera gymnorrhiza, Bruguiera cylindrica, Ceriops Tagal, Rhizophora apiculata, Rhizophora mucronata, Rhizophora Stylosa, dan Lumnitzera racemoza. Nilai kerapatan jenis dan kerapatan relatif tertinggi ditemukan pada jenis Bruguiera gymnorrizha dan Cerops tagal, sedangkan terrendah adalah jenis Rhizophora mucronata dan Lumnitzera racemoza. Nilai frekuensi jenis dan frekuensi relatif tertinggi adalah jenis Bruguiera gymnorrizha sedangkan yang terendah adalah jenis Rhizophora mucronata. Indeks Nilai Penting (INP) semai mangrove tertinggi ditemukan pada jenis Ceriops tagal dan Bruguiera gymnorrizha sedangkan jenis Rhizophora mucronata memiliki INP terrendah dibanding jenis lainnya.Kata kunci: Ekosistem Mangrove; Regenerasi Mangrove; Indeks Nilai Penting
