Analisis Kandungan Dan Aktivitas Antibakteri Ekstrak Daun Sonneratia Alba Dalam Menghambat Pertumbuhan Bakteri Patogen

---

Bacterial resistance to synthetic antibiotics is a global challenge that encourages the search for natural antibacterial agents. This condition causes many bacteria to become insensitive to conventional treatments, so that infections that were previously easy to treat become difficult to control. In the fisheries sector, the uncontrolled use of antibiotics can also pollute the aquatic environment and have long-term impacts on the ecosystem. The research was conducted from December 2024 to June 2025, then samples were taken in the Pecinta Alam Bahari, Dumai City, Riau Province, which aims to test the antibacterial activity of ethanol extracts of S. alba leaves against three pathogenic bacteria, namely A. hydrophila, P. aeruginosa, and S. aureus. The test was conducted by disc diffusion method at extract concentrations of 12.5%, 25%, 50%, and 100%, accompanied by negative (distilled water) and positive (chloramphenicol 30 μg) controls. Results showed that the highest zone of inhibition was obtained against
P. aeruginosa of 19.46 mm at 100% concentration, which is close to the strong category. Moderate inhibition was also observed against A. hydrophila (14.60 mm) and S. aureus (11.00 mm). ANOVA test showed significant differences between treatments (p≤0.05), confirming the potential of S. alba leaf extract as a natural antibacterial agent, especially against Gram-negative bacteria.
Keywords: antibacterial, pathogenic bacteria, Sonneratia alba, zone of inhibition
