Penggunaan bahan alam semakin meningkat dan masih menjadi andalan di beberapa negara berkembang. Penelitian kali ini menggunakan ekstrak etanol dari herba Phyllanthus niruri Linn. Dalam usaha menghambat pertumbuhan Staphylococcus aureus. S. aureus merupakan salah satu mikroflora normal di wajah yang berperan dalam infeksi jerawat. Penelitian ini merupakan penelitian eksperimental menggunakan Rancangan Acak Lengkap dengan 7 perlakuan dan 5 ulangan. Perlakuan yang digunakan adalah pemberian ekstrak etanol herba P. niruri Linn. untuk konsentrasi 5%; 25%; 50%; 75%; 100%, pengenceran menggunakan pelarut DMSO 10%. Kontrol positif menggunakan ciprofloxacin, sedangkan kontrol negatif menggunakan DMSO 10%. Zona hambat yang diperoleh dianalisis menggunakan uji Kolmogorov–Smirnov dan uji homogenitas Levene. Apabila variansi data homogen, maka dilanjutkan analisis dengan Anova yang dilanjutkan dengan uji Post Hoc. Dari perhitungan kontrol negatif, variasi konsentrasi (5%, 25%, 50%, 75%, 100%) dan kontrol positif diperoleh rata-rata zona radikal berturut sebesar 6 mm; 7,46 mm; 7,52 mm; 7,6 mm; 8,52 mm; 8,98 mm; 31,08 mm. Semua variasi konsentrasi ekstrak etanol herba P. niruri Linn. mampu menghasilkan zona hambat radikal dengan zona hambat terbesar tetap dijumpai pada kontrol positif. Hal ini menunjukkan bahwa konsentrasi ekstrak etanol herba P. niruri Linn. yang semakin besar akan berbanding lurus dengan peningkatan aktivitas penghambatan, namun belum seoptimum kontrol positif.   The use of natural materials is increasing and is still a mainstay in several developing countries. This research was used ethanol extract from herb Phyllanthus niruri Linn. in an effort to inhibit the growth of Staphylococcus aureus. S. aureus is one of the normal microflora on the face that helps infection. This research is an experimental study used a completely randomized design with 7 preparations and 5 replications. The treatment used ethanol extract of P. niruri Linn herb. for a concentration of 5%; 25%; 50%; 75%; 100%, the dilution used 10% DMSO solvent. Positive controls used ciprofloxacin, while negative controls used DMSO 10%. The inhibition zone obtained was analyzed using the Kolmogorov-Smirnov test and the Levene homogeneity test. If the data variance is homogeneous, then the analysis is continued with ANOVA followed by the Post Hoc test. From the calculation of negative controls, various concentration (5%, 25%, 50%, 75%, 100%) and positive controls obtained an average radical zone of 6 mm; 7.46 mm; 7.52 mm; 7.6 mm; 8.52 mm; 8.98 mm; 31.08 mm. All variations in the concentration of ethanol extract of P. niruri Linn. herbs able to produce a radical inhibition zone with the largest inhibition zone still found in positive controls. This showed that the greater concentration of ethanol extract of P. niruri Linn. herb. will be directly proportional to the increase in inhibition activity, but not optimal as much as positive control.

Mekai leaves (Pycnarrhena cauliflora Diels.) (P. cauliflora). Are known to contain flavonoid compounds, tannins and phenolics that act as antibacterial agents and are used in the treatment of eye pain. Staphylococcus aureus (S. aureus) is one of the examples of bacterial diseases of eye pain and also a major cause of many infections in communities and health facilities with cases of resistance to various antimicrobial agents. The purpose of this study was to prove the antibacterial activity of mekai leaves ethanol extract against S. aureus bacteria. This research is an experimental research. The stages of this research began by extracting mekai leaves using maceration method with 96% ethanol solvent. Antibacterial activity was tested by the disc method (Kirby-Bauer) using ethanol extract concentrations of mekai leaves (EPC) 20%, 30%, 40%, 50%, 60%, 70%, and 80%, positive control using 25 μg amoxicillin and negative control using DMSO 10%. The measurement results of inhibition zones of mekai leaf ethanol extract 20%, 30%, 40%, 50%, 60%, 70% and 80% respectively were 8.32 mm, 8.32 mm, 8.32 mm, 8.67 mm, 9.00 mm, 8.67 mm, and 8.33 mm. While the positive control measurement of 25 μg amoxicillin against S. aureus is 28.67 mm and the measurement of 10% negative DMSO control does not produce inhibitory zones, so it can be concluded that the ethanol extract of mekai leaves has antibacterial activity, but the area of ​​inhibition zone produced is smaller than amoxicillin 25 µg. The results of statistical tests using Mann Whitney between negative controls with all EPC concentrations obtained significant differences with p values ​​<0.05, it can be concluded that there is antibacterial activity produced at all EPC concentrations.

Staphylococcus aureus is a pathogenic bacterium that spread throughout the world and still a problem that continues to increase both in hospitals and the community. Infections due to S. aureus usually treated with antibiotics, but in some cases, several strains of S. aureus found to be resistant to antibiotics, such as Methicillin-Resistant Staphylococcus aureus (MRSA). Based on the previous research, the ethanol extract from Ajwa and Sukkari dates formed an inhibitory zone against the MRSA bacteria growth. This study aims to determine the inhibition of the ethanol extract from Ajwa and Sukkari variety of dates (Phoenix dactylifera L.) on the S. aureus growth. The ethanol extract from Ajwa and Sukkari dates with a concentration of 5 mg/mL, 10 mg/mL, 15 mg/mL, and 20 mg/mL resulted in the same inhibition zone with a diameter of ≤ 6 mm which categorized as weak (resistant), whereas the positive control ciprofloxacin had a resistance zone with a diameter of 9 mm. This study results concluded that the ethanol extract of Ajwa and Sukkari dates only has a maximum concentration of 20 mg/mL, which is still classified as a low concentration and has not been able to inhibit MRSA bacteria growth.
