Konsep baru untuk pengobatan infeksi bakteri resisten adalah dengan kombinasi antibiotika dengan ekstrak herbal. Ekstrak daun sirih memiliki aktivitas anti bakteri terhadap Escherichia coli dan Staphylococcus aureus kerena daun sirih mengandung metabolit sekunder. Kombinasi ekstrak daun sirih dengan amoksisilin, perlu diuji untuk mengetahui efek antibaktreri masing-masing dibandingkan dengan kombinasinya. Mengetahui karakteristik dan skrining fitokimia simplisia dan ekstrak daun sirih serta uji aktivitas anti bakteri kombinasi amoksisilin dengan ekstrak daun sirih terhadap Escherichia coli dan Staphylococcus aureus. Penelitian ini meliputi ekstraksi serbuk simplisia dengan maserasi, Karakterisasi simplisia untuk mengetahui kadar air, kadar sari larut dalam air, kadar sari larut dalam etanol, kadar abu total dan kadar abu tidak larur asam, serta skrining fitokimia simplisia dan ekstrak daun sirih serta uji aktivitas anti bakteri kombinasi amoksisilin dengan ekstrak daun sirih terhadap Escherichia coli dan Staphylococcus aureus dengan metode difusi agar menggunakan cakram kertas. Hasil penelitian menunjukkan bahwa serbuk simplisia daun sirih memiliki kadar air 3,66%; , kadar sari larut dalam air 22,54%, kadar sari larut dalam etanol 14,65%, kadar abu total9,25% dan kadar abu tidak larur asam 1,03%. Komponen kimia pada simplisia dan ekstrak etanol serbuk daun sirih adalah flavonoid, tannin, saponin dan steroid. Ekstrak etanol serbuk daun sirih menghambat pertumbuhan bakteri Escherichia coli dan Staphylococcus aureus masing-masing pada KHM 8 mg/ml dan 9 mg/ml. Amoksisilin menghambat pertumbuhan bakteri Escherichia coli dan Staphylococcus aureus masing-masing pada KHM 5 g/ml dan 10 g/ml dengan diameter zona hambat 6,83mm dan 7,05 mm. Diameter zona hambat terhadap Escherichia coli dan Staphylococcus aureus meningkat ketika bakteri uji dipaparkan dengan kombinasi ekstrak etanol daun sirih dengan amoksisilin. Dari hasil penelitian menunjukkan bahwa kombinasi Amoksisilin dengan Ekstrak etanol daun sirih menunjukkan efek yang sinergis.

A new concept to treat resistant bacterial infection is using antibiotic combination with herbal extract. Betel leaves extract has an anti-bacteria activity towards Escherichia coli and Staphylococcus aureus since it contains secondary metabolite. Betel leavesextract combination with amoxicillin is needed to be tested to find evaluatetheiranti-bacteria effects and compare with its combination. By finding the characteristics and phytochemical screening simplicia and the betel leaves extract and also the anti-bacteria activity of amoxicillin combination with betel leaves to Escherichia coli and Staphylococcus aureus. This research covered extraction of simplicia powder using macerationmethod. The simplicia characteristics were conductedto determinethe water content, dissolved extract content in water, dissolved extract content in ethanol, total ash, and the acidic undissolved ash, and also the phytochemical screening of simplicia and the betel leaves extract and also the anti-bacteria activity of amoxicillin combination with betel leaves to Escherichia coli and Staphylococcus aureus using diffusion method using paper disc method. The result indicated that the betel leaves powder simplicia had 3.66% of water content, 22.54% of dissolved content extract in water, 14.65% of dissolved content extract in ethanol, 9.25% of ash content, and 1.03% of acidic undissolved ash content. The chemical components in simpliciaand ethanol extract of betel leaves were flavonoid, tannin, saponin, and steroid. The ethanol extract of betel leaves inhibited the growth of Escherichia coli and Staphylococcus aureus bacteria with MIC of 8 mg/ml and 9 mg/ml. Amoxicillin inhibited the growth of Escherichia coli and Staphylococcus aureus bacteria with MIC of5 g/ml and 10 g/ml with diameter of inhibition zone of 6.83 mm and 7.05 mm, respectively. The diameter of inhibition zone towards Escherichia coli and Staphylococcus aureus increased when the bacteria exposed to the combination of betel leaves ethanol extract and Amoxicillin. The research indicated that Amoxicillin combination with betel leaves ethanol extract showed synergistic effect.
