“…Hal ini dikarenakan tidak semua jenis kepiting biola mampu hidup dan bertahan di berbagai wilayah belahan dunia. Jenis-jenis krustasea sebagai fauna bentik sangat umum ditemukan di wilayah ini dimana jenis dan sebarannya sangat bervariasi (Muniarti, 2010).…”

The types of crabs that inhabit coastal and mangrove areas are violin crabs (Uca spp.). The research genetic aspects is important to be able to explain the current status of crabs. The research location in the villages of Payo (geothermal water area) and Tuada (tourist sites). Sampling was done purposively, namely the mangrove area that received the flow of geothermal water sources (Payo Village = 4 samples) and the mangrove area that did not get any influence (Tuada Village = 2 samples). Amplification of Biola crab DNA (Uca Spp.) using primer jgLCO1490 and jgHCO2198 Sequences were analyzed with MEGA5 (Molecular Evolutionary Genetic Analysis) software, genetic distance, DnaSP 4.0 diversity of haplotype (Hd) and nucleotide diversity (π). and Network 4.6 haplotype distribution. Enviromental parameters collected include (temperature, pH land, pH water, salinity and substrate). The results environmental parameters show that differences values at two locations. Identification species crab found family Ocypodidae, genus Uca with species of perplexa, annulipes, crassipes and lactea. The results of genetic matching were found, similar to the results of morphological identification. Genetic diversity was found highly with nucleotides and haplotype varitions. Phylogenetic reconstruction of Uca Spp crabs shows the kinship that occurs between species, although there is a gap (gap) between different species of location. Genetic distance and Fixation Index (Fst) analysis which also shows genetic proximity between species and strong genetic flow between species, despite different locations. Jenis kepiting yang mendiami wilayah pesisir dan mangrove adalah kepiting biola (Uca spp.). Penelitian tentang aspek genetik begitu penting untuk dapat menjelaskan status kepiting saat ini. Lokasi penelitian di desa Payo (Daerah sumber air panas bumi) dan Tuada (Lokasi wisata). Sampling dilakukan secara purposive yaitu area mangrove yang mendapatkan aliran sumber air panas bumi (Desa Payo = 4 sampel) dan tidak mendapatkan pengaruh (Desa Tuada = 2 sampel). Amplifikasi DNA kepiting Biola (Uca spp) menggunakan primer jgLCO1490 dan jgHCO2198 Sekuen dianalisis dengan software MEGA5 (Molecular Evolutionary Genetic Analysis), jarak genetik, DnaSP 4.0 keanekaragaman haplotype (Hd) dan keanekaragaman nukleotida (π) dan Network 4.6 distribusi haplotipe. Parameter lingkungan diukur meliputi (suhu, pH air, pH tanah, salinitas dan substrat). Hasil pengukuran parameter lingkungan memperlihatkan perbedaan nilai kedua lokasi. Identifikasi jenis kepiting ditemukan famili Ocypodidae, genus Uca dengan spesies perplexa, annulipes, crassipes dan lactea.. Keragaman genetik sangat tinggi dengan jumlah nukleotida dan haplotipe yang bervariasi. Rekonstruksi filogenetik memperlihatkan kekerabatan terjadi antar spesies, meskipun terdapat adanya jarak (Gap) antar spesies yang berbeda lokasi. Analisis jarak genetik dan analisis Fixation Index (Fst) yang juga memperlihatkan adanya kedekatan genetik dan aliran genetik yang kuat antar spesies, meskipun berbeda lokasi.

The mangrove ecosystem is one of the most productive ecosystems on earth. This ecosystem provides a lot of functions for the living organism inhabiting here, such as fishes, mollusks, echinoderms, crustaceans, ect. The mangrove crab is one of the common crustaceans that can be found in the mangrove. This Purtunidae crab is very popular due to their role in the food chain as well as for the economic income that has a high value in the market. However, overexploitation may decrease the crab population. This study aimed to investigate the abundance and occurrence of the mangrove crabs from Munjang mangrove, Bangka Belitung Island from August 2020 to June 2021 using baited traps with the line transect method at four zones. A total of four species of mangrove crabs, Scylla olivacea, S. paramamosain, S. serrata and S. tranquebarica, were found in this location and dominated by S. serrata. Shannon diversity index (H’) was a in low category (<1), evenness index range (J) from 0.35 to 0.89, and there was dominant species in this study. The bed sediment iswas dominated by the muddy clay substratum except in zone 4 with sandy. Overall, this location is a suitable habitat for the Scylla spp. And better management is urgently needed before these crabs are exploited by humans.
