Barong shrimp or lobster (Panulirus versicolor) is a fishery commodity with high economic value and great demand. This study aims to determine the genetic characteristics of Panulirus versicolor at the fishing location in the waters of Barrang Caddi Island, Makassar Strait, using primers LCO-1490F and HCO-2198R. Genomic DNA extraction was performed using a Quick-DNA Tissue Miniprep Kit for total isolation. For DNA purity, the elution buffer utilized in this research was specifically selected for its suitability for PCR amplification with KOD FX Neo, providing optimal conditions for efficient genetic analysis. The primary genes used were LCO-1490F with primers GGT CAA CAA ATC ATA AAG ATA TTG G, and HCO-2198R with TAA ACT TCA GGG TGA CCA AAA AAT CA. The study utilized a 1% agarose gel in a 1X TBE buffer at 50 voltage for 45 minutes to move the total DNA and PCR products. The analysis results at sampling stations 0.2-03 showed increasingly smaller genetic distances. Based on the results of BLASTn analysis, each station had the same type of Panulirus versicolor with a similarity of 99-100%. The morphological characteristics included a carapace with a black spot and black and white lines on each abdominal segment. The analysis of genetic variation in the lobster population on Barrang Caddi Island using primers LCO-1490F and HCO-2198R obtained a DNA fragment of 700 bp. The population of Panulirus versicolor lobster on Barrang Caddi Island showed a high level of similarity or low diversity.
