Abstract
Isolat bakteri Staphylococcus aureus asal air limbah pemukiman diuji sensitivitasnya terhadap tiga merek dagang antibiotik tetrasiklin, yaitu Tetracycline Nova (P2), Super Tetra® (P3), dan Limoxin (P4) seberat masing-masing 30 µg, serta kontrol negatif DMSO (P1) menggunakan metode difusi cakram Kirby-Bauer pada media Mueller Hinton Agar (MHA). Penelitian eksperimental laboratoris berdesain Rancangan Acak Lengkap (RAL) dengan 5 kali pengulangan ini mengukur diameter zona hambat pertumbuhan bakteri dan nilai Percentage Inhibition of Diameter Growth (PIDG) setelah inkubasi suhu 37℃ selama 24 jam. Hasil analisis menunjukkan perbedaan nyata (p < 0,05) antar kelompok perlakuan, di mana kontrol negatif (P1) tidak menghasilkan zona hambat, sedangkan kelompok antibiotik menghasilkan diameter zona hambat berturut-turut: Limoxin (P4) sebesar 32,63 ± 2,03 mm, Tetracycline Nova (P2) sebesar 28,66 ± 1,90 mm, dan Super Tetra (P3) sebesar 23,39 ± 0,17 mm, dengan nilai rata-rata PIDG tertinggi pada kelompok Limoxin (443,94 ± 33,96). Berdasarkan standar interpretasi CLSI, ketiga merek dagang tetrasiklin tersebut seluruhnya dikategorikan sensitif (diameter ≥19 mm) dalam menghambat pertumbuhan isolat Staphylococcus aureus asal air limbah pemukiman.
