Abstract:

This study aimed to determine the relationship between the antibacterial activity of Paspalum conjugatum, a type of carabao grass, and its activity on Staphylococcus epidermidis and Escherichia coli. Specifically, it sought to answer the following questions:1. What is the antibacterial activity of carabao grass extract on Staphylococcus epidermidis at different concentrations: 100%, 75%, and 50%? 2. What is the antibacterial activity of carabao grass extract on Escherichia coli at different concentrations: 100%, 75%, and 50%? 3. Is there a significant difference in the antibacterial activity of carabao grass extract against Staphylococcus epidermidis, Escherichia coli and the commercially available antibacterial agent? The study employed a qualitative experimental research design, using random sampling to select three duplicates of each treatment's culture media. The effectiveness of Paspalum conjugatum extract in fighting Staphylococcus epidermidis and Escherichia coli bacteria was assessed through a T-test, while the significance of its effectiveness was evaluated using ANOVA. Based on the study, the result shows the carabao grass extract exhibits antibacterial activity on Staphylococcus epidermidis using 100%, 75%, and 50%. It also shows, the 100%, 75%, and 50% concentration of carabao grass extract did not exhibit antibacterial activity on Escherichia coli. Moreover, there is a significant difference in the antibacterial activity of carabao grass extract against Staphylococcus epidermidis, Escherichia coli and the commercially available antibacterial agent.
