【 摘 要 】

The existence of hard coral is one of the keys to maintain the suistainability of ecosystem in the waters. Currently, the hard coral keeps declining over time due to various disturbances. In addition, hard coral where fish and other organisms live in will directly affect the ecosystem sustainability if the damage still happens. Molecular approach, such as knowing the genetic variation information of coral population can be an informative study to estimate the condition of waters, so that, conservation efforts can be easily done. In this study, we use Lobophyllia corymbosa as a spawning broadcast coral to be the sample which is collected from Sinjai and Luwuk Banggai. The study areas are selected based on geographical patterns which are in the South and East of Sulawesi waters. Since they have a considerable distance, it is likely for them to produce high genetic variations. Genome DNA uses mitochondrial genome that is extracted from coral tissue. The result shows that the genetic diversity is high. From the two major groups provided, there have been 8 haplotypes for all locations. In addition, the L.corymbosa distribution between Sinjai and Luwuk banggai has a high genetic connectivity with 0.6 fixation index.
