Latar Belakang: Infeksi Methicillin-resistant Staphylococcus aureus (MRSA) terus berlanjut meningkat dari waktu ke waktu, ini dapat dipengaruhi oleh adanya resistensi Antibiotik semakin meningkat seiring dengan meningkatnya penggunaan antibiotik irasional. Daun kelor (Moringa oleifera) diketahui memiliki efek antibakteri, terutama gram positif. Tujuan: Mengetahui potensi antibakteri fraksi etil asetat daun kelor (Moringa oleifera) terhadap Methicillin-Resistant Staphylococcus aureus (MRSA) Metode: Penelitian ini dilakukan dengan menggunakan metode makrodilusi fraksi vankomisin dan etil asetat daun kelor (Moringa oleifera). Pengenceran makro aktif vankomisin digunakan sebagai standar dan pembanding dalam penelitian ini karena vankomisin sensitif terhadap MRSA, sedangkan makrodilusi dari fraksi etil asetat digunakan untuk mengetahui potensi antibakteri dari fraksi etil asetat daun kelor (Moringa oleifera) terhadap MRSA. Hasil: Dalam penelitian ini, tidak ditemukan Konsentrasi Hambat Minimum (KHM). dan Konsentrasi Bunuh Minimum (KBM) fraksi etil asetat daun kelor (Moringa oleifera) dalam konsentrasi 1280 g/mL sampai 0,078125 g/mL. Kesimpulan: Tidak ada potensi antibakteri dari fraksi etil asetat daun kelor (Moringa oleifera) terhadap Methicillin-Resistant Staphylococcus aureus (MRSA) ......Background: Methicillin-resistant Staphylococcus aureus (MRSA) infections continue to increase from time to time, this can be influenced by the presence of antibiotic resistance which is increasing along with the increasing use of irrational antibiotics. Moringa leaves (Moringa oleifera) are known to have antibacterial effects, especially gram-positive. Objective: To determine the antibacterial potential of the ethyl acetate fraction of Moringa leaves (Moringa oleifera) against Methicillin-Resistant Staphylococcus aureus (MRSA). Methods: This study was conducted using the macrodilution method of vancomycin and ethyl acetate fractions of Moringa (Moringa oleifera). The macro-active dilution of vancomycin was used as a standard and comparison in this study because vancomycin was sensitive to MRSA, while macrodilution of the ethyl acetate fraction was used to determine the antibacterial potential of the ethyl acetate fraction of Moringa leaves. (Moringa oleifera) against MRSA. Results: In this study, no Minimum Inhibitory Concentration (MIC) was found. and Minimum Kill Concentration (KBM) ethyl acetate fraction of Moringa leaf (Moringa oleifera) in concentrations of 1280 g/mL to 0.078125 g/mL. Conclusion: There is no antibacterial potential of the ethyl acetate fraction of Moringa leaves (Moringa oleifera) against Methicillin-Resistant Staphylococcus aureus (MRSA)
