The objective of this study was to determine the minimum concentration of extract in inhibiting motile motile aeromonad septicaemia. The material used was the stems and leaves of the plant P. grandiflora as much as 10 g. The crushed simplicia was then macerated with aquades with a ratio of 1:10,  then filtered with filter paper and, put in an Erlenmeyer, and evaporated in an incubator at temperature of 30°C. The sensitivity test was performed by placing a paper disc containing extract on the agar medium that had been scratched with bacterial colonies. Clear zone formed around the paper disc was compared with standard classification table for clarifying the inhibition level.  The results showed that stem and leaf extract had inhibition zone against Aeromonas hydrophila bacteria that caused motile aeromonad septicaemia. The best result was obtain at concentration of extract 3.25 mg / L) with an average diameter of 22.67 mm and for leaf extract had a moderate to strong zone for all treatments. These proved that stem and leaf extract of P. grandiflora plant had antibacterial activity and can be used as control of MAS disease caused by A. hydrophila bacteria. Keywords:  Portulaca grandiflora plant, motile aeromonad septicemia,  minimum       inbibition concentration
