This research aims to know the influence of suspension compared to its crude extract on antibacterial activity, especially for Escherichia coli and Staphylococcus aureus . An independent t-test was used as statistical analysis. The yield of the thick extract obtained was 11.153 % ± 1.032 % and it gave an inhibition zone of 7.878 mm ± 0.301 mm for Escherichia coli and 7.484 mm ± 0.636 mm for Staphylococcus aureus . While the suspensions gave an inhibitory zone of 6.293 mm ± 0.754 mm and 5.140 mm ± 0.121 mm for Escherichia coli and Staphylococcus aureus in sequence. The extract’s particle size followed by suspension was 951.167 mm ± 113.662 nm and 474.000 mm ± 38.500 nm. The independent t-test results showed that the extract and suspension significantly influenced the growth of Staphylococcus aureus and Escherichia coli with sig values of 0.012 and 0.028. In conclusion, the extract had a greater effect than the suspension on the growth of Staphylococcus aureus and Escherichia coli .
