Abstract
Abalone Haliotis squamata Reeve 1846 is an abalone that has distribution on the southern coast of Java and Bali in Indonesia. The purpose of this study was to analyze the phylogenetic relationship of H. squamata from the southern coast of Java and Bali based on the cytochrome b (Cyt b) mitochondrial DNA sequence. A total of 38 samples were collected from Java (Binuangeun, Pangandaran, Banyuwangi, and Bali (Buleleng). Samples were extracted, applied using method PCR, and sequencing the method Sanger sequencing di 1st BASE Malaysia. Using primary sequences to applied namely forward primers forward AB-Cytb DivF (5'-TAAGCCAATTCGTAAGGTTC-3') dan primer reverse AB-Cytb DivR (5'-AAAATACCACTCTGGCTGAA-3'). Genetic distance was analyzed using the Kimura 2-parameter method and phylogenetic tree construction was carried out by Neighbor-Joining using the MEGA 7. The result showed that a specific nucleotide difference of 81 bp to 820 bp. The genetic distance between H. squamata intraspecies from the southern coast of Java and Bali is 0.96%-1.06%. This genetic distance is high enough to separate the two populations and form their clusters based on phylogenetic trees. The population of Bali seems to form new subpopulations. The data obtained in this study will be very useful for the management of H. squamata abalone genetic resources related to their sustainability and utilization.
