Identifikasi dan Kelimpahan Bakteri Enterococcus spp. pada Mucus Karang di Perairan Pemuteran, Bali

Indonesia's geographical location is in the world triangle coral region which has the highest number of hard coral species. Coral reefs have various functions as habitats, breeding sites and natural protection from the dangers of abrasion. Domestic pollution has a large contribution to damage to coral reefs. Anthropogenic activity through rivers and runoff containing sediments and organic matter enters the sea causing domestic waste. Enterococcus spp. found in domestic waste as a result of waste originating from human activities in coastal waters, for example derived from dirt, animal feces and urine. Therefore it is used as an indicator of domestic waste pollution. The purpose of this study was to identify and determine whether there was a difference in the abundance of Enterococcus spp. between different coral genera in each research station in order to know the distribution of domestic waste pollution on the Pemuteran waters reefs. The coral mucus sampling site was carried out by purposive sampling method which was chosen based on the presence of coral reefs and coastal conditions. Sampling of coral mucus at each station was taken by selecting randomly three healthy coral genera in each of the three replications of the belt transect of 20 x 2 m. Furthermore, 10 ml coral mucus was inoculated in selective media of Slanetz and Bartley. The presence of Enterococcus spp. on the media identified by red colonies. Differences in the abundance of Enterococcus spp. among the coral genus were analyzed by One-way Anova. The results showed that Enterococcus spp.was identified in all coral mucus in Pemuteran waters and there was no difference in the abundance of Enterococcus spp. among different coral genera at each research station. It is found out that domestic waste has polluted all coral reefs in Pemuteran waters.
