Abstract

dengan Jarak Pagar (Jatropha curcas) yang sebelumnya telah terbukti memiliki aktivitas antibakteri. Penelitian ini bertujuan untuk mengetahui aktivitas antibakteri, konsentrasi optimum antibakteri dan senyawa yang berperan terhadap aktivitas antibakteri dari ekstrak etanol daun jarak merah (Jatropha gossypifolia L.) terhadap Staphylococcus aureus dan Escherichia coli. Ekstraksi senyawa aktif menggunakan metode maserasi dengan pelarut etanol. Pengujian aktivitas antibakteri dilakukan dengan varian konsentrasi 20%, 40%, 60%, 80% dan 100% dengan metode difusi agar. Hasil penelitian menunjukkan bahwa ekstrak etanol daun jarak merah memiliki aktivitas antibakteri terhadap            S.aureus dan E.coli dengan konsentrasi optimum penghambat pertumbuhan bakteri yaitu 60%         (S.aureus) dan 80% (E.coli). Berdasarkan pengujian bioautografi dan KLT dengan eluen                   n-heksana:etil asetat (1:2) menggunakan pereaksi kromogenik senyawa yang diduga berperan terhadap aktivitas antibakteri adalah terpenoid
