Pengaruh Konsentrasi Garam Daun Mangrove Tua (Sonneratia alba) Terhadap Penghambatan Staphylococcus aureus dan Salmonella Sp.
Mangrove (Senoratia alba) is one of the plants that has enormous potential and has halophilic properties or the ability to live in salt-containing areas by making special adaptations molecularly, physiologically, anatomically and morphologically. This study aims to determine MBC and MIC by dilution method, determine the activity of the inhibition zone of S. alba leaf salt, the highest concentration of inhibition zone against S. aureus and Salmonella sp. bacteria. The method used in this research is experimental, which is to test the antibacterial activity of old mangrove leaf salt (S.alba) against bacteria S. aureus and Salmonella sp. with different concentrations consisting of four concentrations namely 12.5% (M1), 6.25% (M2), 3.125% (M3), 1.562% (M4) analyzed descriptively and ANOVA. The parameters analyzed were Minimum Bactericidal Concentration (MBC), Minimum Inhibitory Concentration (MIC), and inhibition zone. The results showed that the MIC value of S. alba leaf salt against S. aureus and Salmonella sp. bacteria was at a concentration of 3.125% and there was no MBC from S. alba salt on S. aureus and Salmonella sp. bacteria. The salt concentrations used were 12.5%, 6.25%, 3.125% and 1, 562% which had inhibition zone diameters on S. aureus bacteria of 14.05 mm, 8.10 mm, 5.04 mm, and 3.80 mm and on Salmonella sp. bacteria of 13.98 mm, 9.10 mm, 5.87 mm, 4.11 mm. The 12.5% concentration was the highest inhibition zone concentration with 8.10 mm against S.aureus bacteria and 9.10 mm Salmonella sp.
