This study aimed to determine the inhibitory effect and the concentration of fingerroot extract to inhibit Staphylococcus aureus growth. The data was analyzed descriptively. Ampicillin was used as positive control, distilled water was used as negative control, and the treatments were given fingerroot extract with a concentration of 5%, 15%, 25%, 35% and 45%. This study was conducted with three replications. The parameter measured was the diameter of inhibition zone formed by diffusion method. The average diameter of inhibition zone of the fingerroot extract were 15% : 10.3 mm; 25% : 13,6mm; 35% : 18,7mm; 45% ± 21,1mm, and at a concentration of 5% the inhibition zone is not formed. The final conclusion is that the fingerroot extract can inhibit the growth of Staphylococcus aureus. The higher concentration of fingerroot extract, the more extensive inhibition zone formed.

Telah dilakukan penelitian secara kualitatif terhadap pengaruh antibakteri dari ekstrak kulit batang matoa (Pometia pinnata. Spp.) terhadap bakteri Gram positif Staphylococcus aureus . Sebelum dilakukan uji antibakteri, sampel yang telah diekstrak secara maserasi diuji fitokimia terlebih dahulu untuk menentukan kandungan metabolit sekunder yang telah diketahui berperan sebagai agen antibakteri. Setelah dilakukan uji fitokimia, ekstrak diuji aktivitas antibakterinya terhadap bakteri Staphylococcus aureus dengan menggunakan teknik difusi agar dengan cara sumuran. Ekstrak dilarutkan pada aquades steril dengan perbandingan 2 g ekstrak pada 2 mL air. Untuk kontrol positif, digunakan ciprofloxacin dan aquades steril sebagai kontrol negatif. Hasil penelitian ini menunjukkan bahwa ekstrak kulit batang matoa memiliki aktivitas antibakteri setelah diinkubasi selama 24 jam pada 37 OC. Dari 3 kali pengulangan dengan masing – masing 3 sumuran, didapat zona hambat masing – masing 16.84 mm, 12.5 mm dan 14.5 mm dengan kontrol positif 29.67 mm serta kontrol negatif 0 mm. Hasil yang diperoleh didukung oleh keberadaan metabolit sekunder hasil uji fitokimia yaitu tanin, flavonoid, terpenoid dan saponin.A qualitative study has done  of the antibacterial effect of matoa (Pometia pinnata) stem bark extract against Gram-positive bacteria Staphylococcus aureus .

Introduction: Staphylococcus aureus infection can cause pyoderma. These days there is a shift in Staphylococcus aureus sensitivity to antibiotics that is marked by the existence of Methicillin-Resistant Staphyloccus aureus, so alternative therapy that is herbal medicine might be needed. There are a lot of medicinal plants in Indonesia, but until today the usage is still minimum. One of the plant genus that is already being used is allium that had been known to have antimicrobial activity. The genus allium that is consumed a lot by Indonesians especially people of North Sumatra is bawang batak (Allium chinense G.Don.). This study is conducted to assess the antimicrobial activity of bawang batak bulbs in several concentrations to MRSA. Methods: This research is an experimental research with agar diffusion method. The extracts were divided into six groups: extracts in concentration level of 6.25%, 12.5%, 25%, 50%, 100% and a negative control (DMSO). The sample size is four per group with total sample of 24. Results: The results showed that the inhibition of bacterial growth occured at the concentration levels of 50% and 100% with inhibition zone diameters of 8.695 mm and 10.545 mm respectively. Extracts with concentration levels of 25%, 12.5% and 6.25% did not show any inhibition. Conclusion: Bawang batak bulbs extract can be used to inhibit the growth of MRSA

The background of this study is Staphylococcus aureus is an anaerobic facultative bacterium and one of the normal microflora in the mouth. However, if it is influenced by predisposing factors, it will become a pathogen. Bidara leaves have antimicrobial activity against Staphylococcus aureus, because Bidara leaves contain various compounds including alkaloids, flavonoids, steroids, tannins and essential oils. The purpose of this study was to determine how much inhibitory power produced by Bidara leaf extract on the growth of Staphylococcus aureus bacteria. This research method is a laboratory experimental research using the diffusion test (wells) method. The sample of this study was Staphylococcus aureus. Dilution of Bidara leaf extract consists of 5 concentrations including: 20%, 40%, 60%, 80%, and 100%. Chlorampheniocol is used for Positive control while Negative control uses aquadest. Based on observations show that the average diameter of inhibitory zone Bidara leaf extract at a concentration of 20% with a diameter of 10.5 mm (R), at a concentration of 60% and 80% with a diameter of 16 mm and 18 mm (I), at a concentration of 100% with a diameter of 24 mm (S). It can be concluded that the higher the concentration of Bidara leaf extract, the inhibition zone formed will increase. So Bidara leaves are good for use in treating infections caused by Staphylococcus aureus bacteria.

Bacteria of the genus Thermoactinomyces have the ability to produce antibacterial bioactive compounds. This bioactive compound can be used for combating diarrheal agents such as Escherichia coli and Staphylococcus aureus. This study aims to determine the antibacterial activity of the metabolite extract from Thermoactinomyces sp. (H24) against Escherichia coli and Staphylococcus aureus. Methanol was used as a solvent for the extraction of bacterial bioactive compounds. Antibacterial activity was analyzed by the diffusion method with several extract concentrations (0.75 mL, 1.5 mL, 2.25 mL, and 3 mL), 10% DMSO as the negative control, and ciprofloxacin as the positive control. Our result shows that Termoactinomyces sp. (H24) extract has an inhibitory effect on the growth of  E. coli and S. aureus with an effective concentration of 2.25 mL (inhibition strength: very strong).
