Tumbuhan ajeran memiliki kandungan senyawa kimia seperti flavanoid, saponin dan fenol yang berpotensi sebagai antibakteri. Antibakteri adalah zat yang dapat membunuh atau menekan pertumbuhan atau reproduksi bakteri. Tujuan penelitian ini untuk mengetahui ekstrak etanol daun ajeran (Bidens pilosa L) sebagai antibakeri Staphylococcus aureus. Metode yang digunakan adalah metode kuantitatif menggunakan Rancangan Acak Lengkap, dengan 5 perlakuan dan 3 ulangan. Analisis menggunakan uji Anova satu jalur (One Way Anova). Jika ada pengaruh yang signifikan maka dilanjutkan dengan uji DMRT. Dalam penelitian ini pembentukan Zona bening menunjukan bahwa ekstrak etanol daun ajeran memiliki kemampuan dalam menghambat pertumbuhan bakteri S. aureus. Semakin luas zona bening yang terbentuk maka semakin kuat senyawa bioaktif dalam menghambat pertumbuhan bakteri.  Pembuktian daya hambat ekstrak daun ajeran terhadap pertumbuhan bakteri S aureus dapat pula diukur melalui menghitung jumlah koloni. Apabila konsentrasi ekstraknya meningkat maka jumlah koloni bakteripun semakin berkurang. Hasil uji daya hambat menunjukan bahwa ekstrak etanol daun ajeran tidak memiliki pengaruh daya hambat yang signifikan terhadap pertumbuhan bakteri S aureus. Dalam penelitian ini perlakuan ekstrak etanol daun ajeran memiliki pengaruh daya antibakteri yang signifikan terhadap pertumbuhan bakteri Staphylococcus aureus. Uji lanjut DMRT menunjukan bahwa (perlakuan P1 10,67 CFU/mL) memiliki nilai yang berbeda nyata.

Eye Pain

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.

This study aims to determine the antimicrobial activity of red fruit paste against Staphylococcus aureus FNCC-0047 and Eschericia coli FNCC-0091 by using ethanol and n-hexane as well as the total plate count value of the patty with red fruit paste added on different observations day. The concentration of paste extract for antimicrobial activity test was 6.25%, 12.5%, 25%, 50%. The calculation of the total value of the burger patty plate is calculated on the 3rd, 7th and 14th d with the red fruit paste content in the formula as much as 0%, 5%, 10%, 15%. The results showed that the fatty acids of red fruit paste were dominated by oleic acid and linoleic acid, which are unsaturated fatty acids and palmitic acid, which are saturated fatty acids. The yield of red fruit paste in n-hexane solvent was higher than ethanol solvent. There was a significant difference (P <0.05) from the use of different solvents to the mean clear zone of the two bacteria tested. The antibacterial activity shown by the ethanol extract and n-hexane extract of red fruit paste was in the inactive category at the 6.12% level, the moderate category at the 12.5% to 25% level and the strong category at the 50% level. There was a significant difference (P <0.05) from the total microbial value in each treatment where the higher the red fruit paste content in the patty, the lower the total microbial value found on each d of observation. The use of red fruit paste at a level of 10% to 15% can withstand the rate of microbial growth
