Abstract
Bawang hitam adalah bawang putih segar yang telah dipanaskan selama beberapa waktu sehingga berubah warna, bau dan juga rasanya. Penelitian ini bertujuan untuk mengetahui apakah bawang hitam sebagai olahan bawang putih memiliki daya antibakteri dengan melihat zona hambat dan pertumbuhan bakteri menggunakan metode difusi dan dilusi yang dimodifikasi. Hasil penelitian ini menunjukkan bahwa Eschericia coli (Gram -), Bacillus subtilis (Gram +), dan Staphylococcus aureus (Gram +) resisten terhadap ekstrak bawang putih dan bawang hitam, sedangkan Pseudomonas aeruginosa (Gram -) sensitif terhadap ekstrak bawang putih dan ekstrak bawang hitam. Konsentrasi bunuh minimum ekstrak bawang hitam terhadap E. coli adalah 85%, S. aureus adalah 90%, dan pada P. aeruginosa serta B. subtilis adalah 100%. Kemudian konsentrasi bunuh minimum ekstrak bawang putih terhadap E. coli adalah 80%, S. aureus adalah 95%, dan pada P. aeruginosa serta B. subtilis adalah 100%.
