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).
ABSTRAKBiota laut memiliki beragam senyawa bioaktif yang berpotensi untuk dijadikan antibakteri pada penyakit udang tambak. Beberapa biota yang memiliki potensi antibakteri yaitu spesies karang lunak Sarcophyton sp., sponge Aaptos sp., rumput laut Sargassum sp. dan Halimeda sp. dan mangrove Avicennia sp. dan Rhizophora sp. Penelitian ini bertujuan untuk menemukan biota laut yang paling berpotensi sebagai antibakteri. Metode yang dilakukan meliputi pengambilan sampel, identifikasi sampel, ekstraksi dan uji aktifitas antibakteri. Hasil yang ditemukan adalah bahwa ekstrak karang lunak Sarcophyton sp. memiliki bioaktifitas terhadap bakteri penyakit udang Vibrio spp2. berkisar 6,3±0, mm, sedangkan Aaptos sp. memiliki bioaktifitas terhadap bakteri Vibrio spp1. berkisar 7. 9+0,1 mm, Vibrio spp2. berkisar 7,2± 0,1 to 7,9 ±0,1 mm, Vibrio spp6. berkisar 7,5±0,2 mm, E. coli berkisar 7,2±0,1 mm dan S. aureus berkisar 15,9±0,2 mm. Aktivitas antibakteri ekstrak rumput laut ditemukkan hanya pada Sargassum sp. yang memiliki aktifitas antibakteri sekitar 7,1±0,0 mm terhadap bakteri Vibrio spp6. dan ekstrak mangrove Rhizopora sp. memiliki bioaktifitas terhadap bakteri Vibrio spp4. sekitar 7,3±0,1 mm dan E. coli sekitar 6,7±0,1 mm. Biota laut yang paling berpotensi sebagai antibakteri adalah sponge Aaptos sp. dengan zona hambat berkisar 15,9±0,2 mm (untuk bakteri S. aureus).
