Uji Fitokimia Dan Analisis Aktivitas Antibakteri Ekstrak Daun Mangrove Bruguiera Sexangula Dalam Menghambat Pertumbuhan Bakteri Patogen
This study was conducted with the aim of analyzing whether there are secondary metabolite compounds in Bruguiera sexangula mangrove leaves, to test the effectiveness of B. sexangula mangrove leaf extract in inhibiting the growth of A. hydrophila, P. aeroginosa, and S. aureus bacteria, to determine the effective concentration in inhibiting the growth of pathogenic bacteria in January - May 2025. The method used is an experimental method using a Completely Randomized Design (CRD) with 1 factor 4 treatment levels namely 12.5%, 25%, 50%, and 100%, negative control (distilled water) and positive control (chloramphenicol) and with 3 replicates then data collected through analysis at the Marine Microbiology Laboratory. B. sexangula leaf extract contains secondary metabolite compounds, namely alkaloids, flavanoids, phenolics and tannins, but no saponin and triterpenoid compounds. Negative results in the saponin and triterpenoid/steroid tests do not reduce the antibacterial potential of B. sexangula extracts, because the main antimicrobial activity is dominated by phenolic compounds, flavonoids, alkaloids, and tannins. So that this leaf extract can inhibit the growth of pathogenic bacteria
A. hydrophila, S. aureus and P. aeruginosa. B. sexangula leaf extract is able to inhibit bacteria A. hydrophila, P. aeruginosa, S. aureus with moderate category. The most effective concentration in inhibiting bacterial growth is at a concentration of 100%, this is in line with each concentration used, which rises proportional to the concentration of the bacteria.
