Abstract

Karang lunak adalah bagian dari ekosistem terumbu karang yang dapat menghasilkan senyawa metabolik sekunder, yang merupakan respon terhadap lingkungan untuk bertahan hidup. Metabolik sekunderini salah satunya adalah sebagai antioksidan. Tujuan penelitian ini untuk melihat senyawa-senyawa yang terkandung dalam karang lunak Sinularia sp dan Lobophytum sp di perairan Pulau Pongok, Bangka Selatan sebagai anti Antioksidan pada kedalaman 3 meter dan 9 meter. Hasil penelitian analisis fitokimia menunjukkan bahwa karang lunak Sinularia sp dan Lobophytum sp mengandung senyawa Alkaloid, Flavonoid, Phenol Hidroquinon, Steroid, Triterpenoid, Tanin, dan Saponin.

Abstract

Marine biota has variety of bioactive compound that is potential to be an antibacterial for shrimp ponds diseases. Some of marine biota has potential as antibacterial i.e. soft coral Sarcophyton sp., Sponge Aaptos sp., seaweeds Sargassum sp. and Halimeda sp. and mangroves Avicennia sp. and Rhizophora sp. species. This study is purposed to find the most potential marine biota as antibacterial. The research method was as follows; sampling, sample identification, extraction and antibacterial activity test. The results is soft coral and sponge extract Sarcophyton sp. has bioactivity against of shrimp bacteria pathogen such as Vibrio spp2. bacteria for around 6.3±0.1 mm, while Aaptos sp. has bioactivity against Vibrio spp1. bacteria for around 7.9+0.1 mm, Vibrio spp2. bacteria for around 7.2± 0.1 to 7.9±0.1 mm, Vibrio spp6. bacteria for around 7.5±0.2 mm, Escherichia coli for around 7.2±0.1 mm and Staphylococcus aureus for around 15.9±0.2 mm. Seaweed extract activity found only of Sargassum sp. which has antibacterial activity against for around 7.1±0.0 mm for Vibrio spp6. and mangrove species activity has Rhizophora sp. extract which has bioactivity against Vibrio spp4. were 7.3±0.1 mm and E. coli bacteria were 6.7±0.1 mm. The most potential marine biota as antibacterial is showed on sponge Aaptos sp.. with an inhibitory zone for around 15.9±0.2 mm (for S. aureus bacteria).

Abstract

Soft corals have bioactive compounds to potential as marine natural products, but the over exploitive to destroy of that ecosystem. Therefor endophyte microbial isolation can be effort to prevent that matters. This research aimed to isolate and characteristic on the entophyte microbial of soft coral Lobophytum sp and Sinularia sp that collated from Maspari island waters. Methodology of research were establishing growth of microbial samples (bacterial and fungal), isolation and characterization. Total of bacteria colony of Lobophytum sp were obtained about 5 isolates, and Sinularia sp were about 4 isolates. The macroscopic characteristic showed that whole bacteria had white colors. That colonies had undulate, entire and curl (the edge of colony) and circular and irregular (for colony shape). For fungal of Lobophytum sp were obtained about 3 isolates, while Sinularia sp had only one isolate. The fungal colonies macroscopic characteristic showed yellow, green and white color, while shaped and edges colonies were thickened. spread, thin, round, dark, and the whole of isolates had filamentous hyphae.
