Abstract

Skripsi ini membahas pengaruh ekstrak kulit buah manggis dalam menghambat pertumbuhan bakteri Escherichia coli ATCC 25922 dan bakteri Staphylococcus aureus ATCC 25923. Metode penelitian yang digunakan adalah metode Post Test Control Group Design. Ekstrak dibuat dengan cara maserasi, kemudian dilakukan uji sensitivitas bakteri dengan metode Kirby Bauer diffusion test yang diduplikasi secara sebanyak 4 kali. Hasil penelitian didapatkan bahwa terbentuk zona hambat ekstrak kulit buah manggis terhadap Staphylococcus aureus ATCC 25933 dengan diameter zona hambat sebesar 10.23 mm, 10.95 mm, 13.45 mm, 16 mm, 19.5 mm pada konsentrasi ekstrak 10%, 30%, 50%, 70% dan 100% dan tidak terdapat adanya zona hambat ekstrak kulit buah manggis terhadap bakteri Escherichia coli ATCC 25922. Penelitian ini masih memerlukan penelitian lanjutan yang disempurnakan metodologi dan teknisnya Kata kunci: ekstrak kulit buah manggis, Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 25923, Kirby Bauer diffusion test. The aim of this research is the effect of mangosteen pericarp extract toward inhibits the growth of bacteria Escherichia coli ATCC 25922 and bacteria Staphylococcus aureus ATCC 25923. This research is Post Test Control Group study. Maseration method is used as the extraction method, after that, antibacterial sensitivity testing was done by Kirby Bauer diffusion test that had been duplicated for four times. The result of this study is mangosteen pericarp extract showed inhibition against Staphylococcus aureus ATCC 25923 with diameter zone of inhibition 10.23 mm, 10.95 mm, 13.45 mm, 16 mm, 19.5 mm on 10%, 30%, 50%, 70% dan 100% extract consentration and there is no zone of inhibition on mangosteen pericarp extract against Escherichia coli ATCC 25922. This research needs to be done with better its methodology and technique Key words: Mangosteen pericarp extract, Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 25923, Kirby Bauer diffusion test.
