ABSTRAK

Telah dilakukan penelitian yang bertujuan untuk menguji aktivitas antibakteri ekstrak biji kopi robusta terhadap bakteri Escherichia coli pada konsentrasi 10%, 50% dan 100%. Ekstraksi menggunakan metode maserasi dengan pelarut etanol 96%. Pengujian antibakteri menggunakan metode difusi agar dengan cara sumuran. Berdasarkan hasil penelitian, ekstrak biji kopi robusta dapat menghambat bakteri Escherichia coli. Konsentrasi 10%, 50% dan 100% ketiganya memberikan zona hambat yang berbeda. yaitu semakin besar konsentrasi eksrak biji kopi robusta maka semakin besar zona hambat yang terbentuk.
