Abstract
Penelitian uji daya hambat dan skrining fitokimia ekstrak daun Macaranga tanarius (L.) M.A sebagai antibakteri Salmonella typhi telah dilaksanakan pada bulan Oktober sampai November 2016. Penelitian ini bertujuan untuk mendeskripsikan morfologi tumbuhan, mengetahui aktifitas antibakteri, serta kandungan kimia ekstrak daun M. tanarius (L.) M.A. Penelitian in menggunakan metode deskriptif, analisis skrining fitokimia,dan eksperimental dalam uji daya hambat ekstrak yang disusun dalam Rancangan Acak Lengkap (RAL) dengan 6 perlakuan dan 3 ulangan. Perlakuan meliputi pemberian konsentrasi ekstrak daun 10%, 20%, 40% dan 60%, serta kontrol positif (kloramfenikol 1%) dan kontrol negatif (Na-CMC 1%). Hasil penelitian menunjukan bahwa ekstrak tumbuhan M. tanarius (L.) M.A pada konsentrasi 60% menghasilkan zona hambat yang paling besar yaitu 20 mm, lebih tinggi dibandingkan konsentrasi lainnya, namun masih lebih kecil dibandingkan kontrol positif. Hasil skrining fitokimia menunjukan adanya senyawa alkaloid, tanin dan saponin pada tumbuhan Macaranga tanarius (L.) M.A
