Uji Aktivitas Antibakteri Ekstrak Daun Dan Kulit Batang Avicennia Alba Terhadap Bakteri Patogen (Pseudomonas Aeruginosa, Aeromonas Salmonicida, Staphylococcus Aureus)

ABSTRACT
This research was conducted out in November 2020-February 2021 at the
Laboratory of Fish Quarantine and Quality Control (BKIPM) Pekanbaru, Riau.
The aims of this research was to test the activity of A. alba mangrove leaf extracts
and stems in inhibiting the growth of pathogenic bacteria P. aeruginosa, A.
salmonicida and S. aureus. The research method used in this study is the
experimental method. The sampling was conducted at the location of Marine
Station UNRI Purnama Dumai. The results showed that A. alba leaf extract has
the highest inhibitory power at a concentration of 100% with an average of 4.37–
5.13 mm. The highest inhibitory power was against S. aureus (5.13 mm) and the
lowest inhibition power was found in A. salmonicide (4.37 mm). The lowest
inhibiton was found at a concentration of 12.5% with an average of 0.45–0.67
mm. The stem extract of A. alba had the highest inhibitory power at a
concentration of 100% with an average of 6.17–7.47 mm. The highest inhibition
power was against S. aureus 7.47 mm and the lowest inhibition power was found
in A. salmonicida (6.17 mm). The lowest inhibitory was at a concentration of
12.5% with an average of 1.52–2.29 mm. Based on the criteria for the strength of
antibacterial activity of stem extract A. alba was in the medium category and the
leaf extract was in the weak category.
