Abstract
Bakteri Staphylococcus aureus adalah bakteri flora normal yang
dapat menyebabkan penyakit infeksi pada tubuh. Daun kemangi
(Ocimum sanctum L) dan daun sirsak (Annona muricata L) memiliki
kandungan senyawa yang dapat digunakan sebagai antibakteri. Tujuan
penelitian ini adalah untuk mengetahui aktivitas antibakteri kombinasi
ekstrak etanol daun kemangi dengan daun sirsak terhadap bakteri S.
aureus.
Penelitian ini menggunakan metode maserasi pada daun
kemangi dan daun sirsak menggunakan pelarut etanol 96%. Metode
dilusi digunakan untuk menetapkan nilai KHM dan KBM berdasarkan
perbandingan yang paling efektif dalam membunuh bakteri dengan seri
pengenceran mulai dari 50%; 25%; 12,5%; 6,25%; 3,12%; 1,56%;
0,78%; 0,39%; 0,19%; 0,09%. Metode difusi dengan kertas cakram
menggunakan perbandingan (1:1); (1:2); (2:1). Aktivitas antibakteri
terbaik dilakukan uji pola kombinasi menggunakan metode pita kertas.
Analisis data menggunakan SPSS dengan nilai signifikan (p>0,05).
Penelitian menunjukkan bahwa ekstrak daun kemangi memiliki
nilai KBM 12,5% dan daun sirsak memiliki KBM 12,5%. Kombinasi
(1:1) memiliki diameter 20,26±1,40. Kombinasi (1:2) memiliki
diameter 26,56±1,35. Kombinasi (2:1) memiliki diameter 19,83±1,00.
Kombinasi terbaik pada konsentrasi (1:2). Efek kombinasi antar ekstrak
adalah adiktif.
Staphylococcus aureus bacteria are part of the normal flora and
can spread infectious illnesses throughout the body. Basil leaves
(Ocimum sanctum L.) and soursop leaves (Annona muricata L.) both
contain substances that can be utilized as antibacterials. The purpose of
this study was to examine the antibacterial activity of a combination of
basil leaf ethanol extract and soursop leaves against S. aureus bacteria.
This study employed a maceration method on basil and soursop
leaves with a 96% ethanol solvent. The dilution method was used to
calculate the Minimum Inhibitory Concentration (MIC) and Minimum
Bactericidal Concentration (MBC) values based on the most effective
ratio in killing bacteria, with a dilution series beginning at 50%, 25%,
12.5%, 6.25%, 3.12%, 1.56%, 0.78%, 0.39%, 0.19%, and 0.09%. The
diffusion method using paper discs employed the following ratios:
(1:1), (1:2), and (2:1). The best antibacterial activity was carried out
through a combination pattern test using the paper tape method. Data
analysis used SPSS with significant values (p>0.05).
According to research, basil leaf extract had a MBC value of
12.5% and soursop leaves had a MBC value of 12.5%. The
combination (1:1) had a diameter of 20.26 ± 1.40. The combination
(1:2) had a diameter of 26.56 ± 1.35. The combination (2:1) had a
diameter of 19.83 ± 1.00. The best combination in concentration (1:2).
Therefore, the combined effects of the extracts were addictive.
