Abstract

Rajungan crab (Portunus sp.) is one type of crab that has a fairly high commodity value, this species has a fairly wide distribution covering the Indo-Pacific Ocean and also offshore, this crab has an important role in ecological stability. Portunus sp. has a more attractive appearance compared to other crabs. The purpose of this study is to look at the (dominant) crab species found in January (west wind season) in the waters of Percut Sei Tuan based on the genes CO1, and phylogenetics (kinship relationship) of Portunus sp. in the waters of Percut with Portunus sp. in NCBI or Genebank. The method used in this study is DNA isolation on specimens using the Favorgen kit locus of the CO1 gene in the genome of the Portunus sp. amplified by PCR technique with LCO1940 (forward) and HCO2198 (reverse) primers. The results of the research that have been carried out have found 3 species from the genus Portunus, namely P. sanguinolentus, P. trituberculatus and P. pelagicus. Of the three species found in the Percut Sei Tuan Waters, P. trituberculatus and P. pelagicus have a closer kinship relationship compared to P. sanguinolentus, based on the percentage of AT content and GC content, the AT content is higher at 61.03% which means that the three species have primitive properties. The genetic distance between P. sanguinolentus and P. trituberculatus is closer (19.32) compared to P. pelagicus. Based on the phylogenetic tree reconstruction, P. trituberculatus and P. sanguinolentus are closer to P. pelagicus with the Neighbor-Joining method and the Kimura-2-Parameter calculation model. Thus, it can be concluded that DNA barcoding using the CO1 gene locus can be used as a method in identifying Portunus sp. molecularly and kinship relationships with other species.

Abstract

Anadara sp. clams are very popular clams among the community. Anadara sp. also usually live in waters with muddy and sandy surfaces. DNA barcoding is a barcode sequence to identify unknown species. CO1 is a molecular marker commonly used in molecular research on animals. The purpose of this study was to determine the species of Anadara sp. clams found in Percut Sei Tuan Waters using gene markers, the diversity of Anadara sp. clams using CO1 Gene Markers, and the kinship of Anadara sp. clams found in Percut Sei Tuan Waters. This study has 4 stages, namely DNA isolation using the Favorgen kit, PCR amplification, electrophoresis and sequencing. The DNA sequencing results were analyzed using the MEGA 11 application. The results showed that of the three samples that had been analyzed using the CO1 gene marker obtained using BLAST and NCBI, namely the Anadara granosa, Anadara antiquata, and Anadara gubernaculum samples. With the calculation results of higher AT content (28.9%) and lower GC content (20.12%) which states that the species is more primitive. In the pairwise distance matrix, the samples of Anadara antiquata (Percut Sei Tuan) and Anadara granosa (Percut Sei Tuan) which are in the same clade with different sub clades have a genetic distance ranging from 111.45 to 213.77. The phylogenetic tree also shows that the three samples have a close kinship relationship.
