Research methods include isolating bacteria from seagrass sediments, antibacterial testing against S. aureus and E. coli bacteria, identifying bacteria using the DNA method, and testing the presence of biosynthetic gene clusters. The results showed that the mangrove sediment bacterial isolate with the isolate code B.26.ST.3.4 had the highest antibacterial activity with a value of 28.05 ± 0.9192 against the pathogen E. coli and 23.45 ± 10.2530 against the pathogen S. aureus.
