Analisis Kandungan Dan Aktivitas Antibakteri Ekstrak Daun Sonneratia Alba Dal…
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 environme…

Coral reefs play a crucial role in maintaining the stability of marine ecosystems. Healthy coral growth is often indicated by the presence of symbiotic zooxanthellae within the coral tissue. The density of zooxanthellae varies and is influenced by several factors. Depth affects these limiting factors—such as light intensity, temperature, and ocean acidity—which in turn impacts zooxanthellae…
