Antibacterial Activity Test of Betadine Stem Sap Extract (Jatropha Multifida L.) Against the Growth of Pseudomonas Aeruginosa Bacteria in an In-Vitro

Introduction

In recent years, there has been a growing awareness of the importance of utilizing plants as an alternative treatment for various diseases and to improve health. One of the plants that has the potential as a drug is the betadine plant (Jatropha multifidea L.). This plant has various benefits, especially the sap, leaves, fruit, and seeds. Betadine stem sap contains compounds that have antimicrobial properties, including saponins, tannins, flavonoids, and labaditin. Pseudomonas aeruginosa bacteria, known as opportunistic pathogens and causes of nosocomial infections, are one of the targets of testing the antibacterial activity of this extract.

The Importance of Antibacterial Activity Testing

Antibacterial activity testing is crucial in the development of new drugs to overcome bacterial infections that are resistant to conventional antibiotics. Pseudomonas aeruginosa bacteria are known to cause a wide range of infections, including respiratory tract infections, urinary tract infections, and skin infections. The increasing resistance of these bacteria to conventional antibiotics has made it essential to explore alternative treatments. The betadine plant, with its antimicrobial properties, has the potential to be used as an alternative treatment for bacterial infections.

Research Purposes

This study aims to evaluate the antibacterial activity of betadine stem sap extract to the growth of pseudomonas aeruginosa in an in-vitro. By using the True Experimental Laboratory Research Design and Post-Test Only Control Group design, researchers seek to obtain objective data on the effectiveness of this extract.

Methodology

In this study, Betadine stem sap extract was tested using several concentrations, namely 25%, 50%, 75%, and 100%. As a positive control, 10% gentamicin cream is used, while the DMSO solution functions as a negative control. The method used is the diffusion of Kirby-Bauer, where the bacterium pseudomonas aeruginosa is planted on the media for nutrition, then incubated for 24 hours. After that, the inhibition zone is obtained and measured using the calipers. The research data was analyzed by the One-way anova test to determine the significance of the difference in yield.

Research Result

The results showed that the concentration of 50% betadine stem sap extract produced the highest average zone, which was 12.725 mm, with a standard deviation of 0.2500 mm. Conversely, a 100% concentration shows the lowest average zone, which is 8.675 mm, with a standard deviation of 0.5620 mm.

Discussion

Antibacterial mechanisms contained in betadine stem sap extracts can be associated with saponin, tannin, flavonoids, and labaditin which turned out to be able to intervene in the growth of pseudomonas aeruginosa bacteria. Saponin, for example, functions to form a complex with a bacterial cell membrane and can trigger cell lysis, while flavonoids acts as an anti-inflammatory agent and can reduce free radicals that can damage cells.

Conclusion

Based on the results and analysis conducted, it can be concluded that betadine stem sap extract has significant antibacterial activity in inhibiting the growth of pseudomonas aeruginosa. 50% concentration has proven to be the most effective. This study shows that medicinal plants, such as betadine, can be used as an alternative in the development of new drugs to overcome bacterial infections that are resistant to conventional antibiotics.

Future Research Directions

Thus, it is important to continue to conduct further research on the antimicrobial potential of other plants and their mechanisms, as well as its use in the field of public health. The development of new drugs from medicinal plants can provide a sustainable and effective solution to overcome bacterial infections. Additionally, the study of the antibacterial activity of betadine stem sap extract can provide valuable insights into the development of new treatments for bacterial infections.

Limitations of the Study

This study has several limitations. Firstly, the study only tested the antibacterial activity of betadine stem sap extract against pseudomonas aeruginosa bacteria. Further studies are needed to test its activity against other types of bacteria. Secondly, the study only used a limited number of concentrations of betadine stem sap extract. Further studies are needed to determine the optimal concentration of betadine stem sap extract for antibacterial activity.

Implications of the Study

The study has several implications. Firstly, it shows that medicinal plants, such as betadine, can be used as an alternative in the development of new drugs to overcome bacterial infections that are resistant to conventional antibiotics. Secondly, it highlights the importance of further research on the antimicrobial potential of other plants and their mechanisms, as well as its use in the field of public health.

Recommendations for Future Research

Based on the results of this study, several recommendations can be made for future research. Firstly, further studies are needed to test the antibacterial activity of betadine stem sap extract against other types of bacteria. Secondly, further studies are needed to determine the optimal concentration of betadine stem sap extract for antibacterial activity. Thirdly, further studies are needed to investigate the mechanisms of antibacterial activity of betadine stem sap extract.

Conclusion

In conclusion, this study has shown that betadine stem sap extract has significant antibacterial activity in inhibiting the growth of pseudomonas aeruginosa. 50% concentration has proven to be the most effective. This study shows that medicinal plants, such as betadine, can be used as an alternative in the development of new drugs to overcome bacterial infections that are resistant to conventional antibiotics. Further research is needed to fully understand the antimicrobial potential of betadine stem sap extract and its mechanisms of action.
