Abstract
Staphylococcus aureus bacteria are resistant to several kinds of antibiotics, so there is a need for natural antibiotics derived from plants, namely aloe vera. The objective of this study was to determine the effect of aloe vera leaf extract in inhibiting the growth of Staphylococcus aureus bacteria. The type of research used was experimental using the disc diffusion method with a total of 25 samples with five concentrations of 20%, 40%, 60%, 80% and 100% then the data were analyzed using the One Way ANOVA test. The result is that aloe vera extract can inhibit the growth of Staphylococcus aureus bacteria, it is proven by the presence of a disc zone at 100% concentration with a diameter of 11.5 mm. The results of statistical analysis with the One Way ANOVA test, in a value of 0.000, meaning that there was a significant difference. The conclusion obtained is that aloe vera extract can slow down the growth of Staphylococcus aureus bacteria but based on the standard value of sensitivity of an aloe vera extract bacteria with the highest concentration it cannot be used as an antibiotic because it is less than the standard value of 14 mm.
Highlights
Staphylococcus aureus is a gram- the potential as antibiotics
The objetive of this research was to inhibit the growth of Staphylococcus determine the effect of aloe vera extract in bacteria which is expected to be safer, more forming the inhibition zone of efficient, and effective by creating natural Staphylococcus aureus bacteria
Testing of Staphylococcus aureus strains was carried out to ascertain the type of bacteria
Summary
Staphylococcus aureus is a gram- the potential as antibiotics. One of the positive bacterium that has a round plants that is cheap and available to morphology and can live in colonies like be used as natural antibiotics is Aloe vera grapes and can secrete pigment (Country, 2014). Other Eteraloin resistant to Aloe vera can be used diseases that can arise are infections in the as antibacterial, antiseptic, and antibiotic. Staphylococcus aureus bacteria which is Staphylococcus aureus bacteria are one of the causes of infection (Natsir, resistant to several kinds of antibiotics due 2013). The objetive of this research was to inhibit the growth of Staphylococcus determine the effect of aloe vera extract in bacteria which is expected to be safer, more forming the inhibition zone of efficient, and effective by creating natural Staphylococcus aureus bacteria. Before carrying out the extract sensitivity test, you must do a bacterial strain test because to find out whether the bacteria used was Staphylococcus aureus with the ATCC 25923 strain, a catalase test, coagulase test and gram staining re carried out.
