ABSTRAK
Jumiana : 2016. "Uji daya hambat antibakteri ekstrak n-heksan rumput laut (Gracilaria sp) terhadap pertumbuhan bakteri Staphylococcus aureus . Karya Tulis Ilmiah. Program Studi DIII Farmasi Fakultas Olahraga dan Kesehatan, Universitas Negeri Gorontalo. Dibimbing oleh Moh. Adam Mustapa.,S.Si.,M.Sc dan Nurain Thomas.,S.Si.,M.Si.Apt
Rumput Laut (Gracilari sp) mengandung metabolit sekunder yang merupakan senyawa bioaktif yang berperan sebagai antibakteri. Penelitian ini bertujuan mengetahui adanya daya hambat ekstrak n-heksan rumput laut (Gracilaria sp) terhadap bakteri Staphylococcus aureus dan juga untuk mengetahui daya hambat dari masing-masing konsentrasi ekstrak n-heksan rumput laut (Gracilaria sp) terhadap pertumbuhan bakteri Staphylococcus aureus.
Rumput laut di ekstrak hingga didapatkan ekstrak kental yang akan diuji pada antibakteri. Metode yang digunakan untuk menguji daya hambat ini adalah metode difusi agar (difusi cakram) dengan menggunakan ekstrak rumput laut sebanyak 3 konsentrasi yaitu 5%, 15%, 25% serta control negatif dan control positif eritromisin.
Dari masing-masing konsentrasi yang digunakan yaitu 5%, 10%, 15%, 20% dan 25% ekstrak n-heksan rumput laut memiliki zona hambat dengan rata-rata sebesar 9 mm, 11,6 mm, 12,3mm, 13 mm dan 14,3 mm
Kata Kunci : Daya hambat antibakteri ekstrakt rumput laut (Gracilaria sp), Bakteri Staphylococcus aureus
ABSTRACT
Jumiana : 2016. "antibakteri's resistivity quiz extracts n hexane grass to go out to sea (Gracilaria sp) to bacteria growth Staphylococcus aureus . Opus Writes Scientific. Studi DIII's program Sporting Faculty Pharmaceutical and health, Gorontalo's Country university. Led by Moh. Adam Mustapa.,S. The.,M. Sc and Nurain Thomas.,S. The.,M. The. Apt
Browsing Oceanic (Gracilari sp) containing secondary metabolit one constitutes bioaktif's compound that antibakteri's personation. This research intent knows to mark sense extract resistivity n hexane grasses to go out to sea (Gracilaria sp) to bacteria Staphylococcus aureus and also to know resistivity of each concentration extracts n hexane grass to go out to sea (Gracilaria sp) to bacteria growth Staphylococcus aureus .
Browsing oceanic at extracts until gotten by viscous extract that will be tested on antibakteri. Method that is utilized to test this resistivity is that diffusion method (the disk diffusion) by use of grass extract goes out to sea as much 3 concentrations which is 5%, 15%, 25% and control is negatives and control is eritromisin's positives.
Of each concentration that is utilized which is 5%, 10%, 15%, 20% and 25% extract n hexane grass to go out to sea have constraining zonas with averagely as big as 9 mm, 11,6 mm, 12,3mm, 13 mm and 14,3 mm
Key word : antibakteri ekstrakt's resistivity grasses to go out to sea (Gracilaria sp), Staphylococcus Aureus's bacteria
