Abstract
Daun Laruna dan daun Sirsak merupakan tanaman yang mengandung senyawa saponin, flavonoid, tanin, triterpenoid, steroid, minyak atsiri yang memiliki efek sebagai antibakteri. Berdasarkan penelitian sebelumnya daun Laruna dan daun Sirsak mempunyai aktivitas antibakteri terhadap bakteri Staphyloccocus aureus. Penelitian ini bertujuan untuk menguji dan membuktikan aktivitas antibakteri kombinasi ekstrak etanol daun Laruna dan daun Sirsak terhadap Staphylococcus aureus.
Daun Laruna dan daun Sirsak diekstraksi menggunakan metode maserasi dengan etanol 96% sebagai pelarutnya. Uji yang dilakukan yaitu skrining fitokimia, pengujian aktivitas antibakteri menggunakan metode dilusi dan difusi (metode cakram). Perbandingan konsentrasi yang digunakan adalah 1:1, 1:2, 2:1 untuk pengujian aktivitas antibakteri dengan kontrol positif gentamicin.
Hasil dari penelitian menunjukan bahwa kombinasi ekstrak etanol daun laruna dan daun sirsak memiliki aktivitas antibakteri pada Staphylococcus aureus dengan konsentrasi bunuh minimum sebesar 6,25% dan 12,5% dan perbandingan paling efektif dari kombinasi ektrak etanol daun laruna dan daun sirsak yaitu 2:1 dengan pola efek kombinasi yang dihasilkan adalah sinergis.
Laruna leaves and soursop leaves are plants that contain saponin compounds, flavonoids, tannins, triterpenoids, steroids, essential oils which have antibacterial effects. Based on previous research, Laruna leaves and Soursop leaves have antibacterial activity against Staphyloccocus aureus bacteria. This research aims to test and prove the antibacterial activity of a combination of ethanol extracts of Laruna leaves and Soursop leaves against Staphylococcus aureus.
Laruna leaves and soursop leaves were extracted using the maceration method with 96% ethanol as the solvent. The tests carried out were phytochemical screening, antibacterial activity testing using dilution and diffusion methods (disc method). The concentration ratio used was 1:1, 1:2, 2:1 to test antibacterial activity with the positive control gentamicin.
The results of the research showed that the combination of ethanol extracts of laruna leaves and soursop leaves had antibacterial activity on Staphylococcus aureus with a minimum kill concentration of 6.25% and 12.5% and the most effective ratio of the combination of ethanol extracts of laruna leaves and soursop leaves was 2:1 with the resulting combination effect pattern being synergistic.
