Antibacterial Activity of Phyllophorus sp. Methanol Crude Extract on Vibrio alginolyticus and Vibrio harveyi

Utilization of natural materials sourced from the sea is very promising. These ingredients can function as antibacterials that are useful in a number fields. This study aims to explore extract cucumber Phylloporus sp. an antibacterial agent for Vibrio alginoliticus and harveyi. The diffusion method was carried out with three treatments starting at doses 500, 1000 1500 mg/L replications each treatment. Positive control antibiotic Chloramphenicol 100 mg/ml (0.01%) negative dimethylsulfoxide (DMSO) 10%. test results showed able inhibit both types bacteria, visible inhibition zone formed. In average formed 0.433 ± 0.0288. harveyii inhibited by 0.516 0.104. Inhibition lower than which commercial antibacterial.
