Abstract

Species identification is very important and an important part of bioecological studies, so phylogenetic studies of Cerithidea anticipata (Iredale, 1929) was conducted in September 2020 to identify C. anticipata (Iredale, 1929) based on DNA barcoding techniques. Samples of C. anticipata (Iredale, 1929) were collected from the mangrove ecosystem of Payum Merauke Beach Papua (Indonesia), where the genes used were primary COI Gene forward LCO1490 and reverse HCO2198. The result of DNA amplification obtained DNA sequence length of 660 bp, then based on the identification of Basic Local Alignment Search Tools (BLAST) obtained a similarity level of 98.42% and phylogenetic reconstruction showed the existence of grouping based on the degree of similarity and genetic distance between populations.Keywords: Cerithidea anticipata; COI genes; DNA barcoding; phylogeneticsAbstrakIdentifikasi spesies sangat penting dilakukan dan menjadi bagian penting dalam studi bioekologi, sehingga kajian filogenetik Cerithidea anticipata (Iredale, 1929) telah dilakukan pada bulan September 2020 dengan tujuan untuk mengidentifikasi C. anticipata (Iredale, 1929) berdasarkan teknik DNA barcoding. Sampel C. anticipata (Iredale, 1929) dikoleksi dari ekosistem mangrove Pantai Payum Merauke Papua (Indonesia), dimana gen yang digunakan adalah Gen COI primer forward LCO1490 dan reverse HCO2198. Hasil dari amplifikasi DNA diperoleh panjang sekuen DNA 660 bp, kemudian berdasarkan identifikasi Basic Local Alignment Search Tools (BLAST) diperoleh tingkat kemiripannya 98.42% dan rekonstruksi filogenetiknya memperlihatkan adanya pengelompokan berdasarkan tingkat kemiripan maupun jarak genetik antar populasi.Kata kunci: Cerithidea anticipata; Gen COI; DNA barcoding; filogenetik

Abstract

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

Abstract

The existence and sustainability of mangrove forests have a significant role in the environment and communities around the coast. Mangrove ecosystems also have complex systems including plant and animal organisms that interact with one another and play an essential role in maintaining and protecting the coastline. This research was conducted to analyze the potential for the regeneration of mangrove seedlings in the coastal area of Dafi Village, Biak Numfor Regency. Data collection was carried out using the belt transect method. Analysis of species composition and structure of mangrove vegetation 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. Bruguiera gymnorrizha species had the highest density, frequency, and dominance values, while the lowest relative dominance and dominance were found in Lumnitzera racemoza. The highest IVI tree level values ​​were Ceriops tagal and Bruguiera gymnorrhiza. Mangrove forests in this area are still in natural condition, and the existence of mangrove ecosystems supports the lives of people around the island.

Penelitian ini dilakukan dengan tujuan menganalisis struktur komunitas mangrove di Perairan Kampung Dafi  Kabupaten Biak  Numfor.Pengumpulan data ekosistem mangrove dilakukan dengan menggunakan metode belt transek. Analisis komposisi jenis dan struktur vegetasi mangrove 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. Jenis Bruguiera gymnorrizha memiliki nilai kerapatan, Frekuensi dan dominansi tertinggi, sedangkan dominansi jenis dan dominansi relatif terendah pada mangrove jenis Lumnitzera racemoza. Nilai INP tingkat pohon yang paling tinggi adalah Ceriops tagal dan Bruguiera gymnorrhiza. Hutan mangrove pada kawasan ini masih berada dalam kondisi alami, dan keberadaan ekosistem mangrove menjadi penopang bagi kehidupan masyarakat di sekitar pulau.
