ISOLASI, IDENTIFIKASI DAN UJI AKTIVITAS ANTIBAKTERI MINYAK ATSIRI DARI KULIT KAYU AKWAY (Drimys arfakensis Gibbs) ASAL PEGUNUNGAN ARFAK PAPUA

ABSTRACT
 
 Isolation of essential oil by steam and water distillation method, identification GC-MS antibacterial activity test against akway bark (D. arfakensis Gibbs) have been carried out. The results showed that the component was composed 142 compounds, which were dominated 10 components. ten suspected components are: 4,5-dimethyl-1-heksen (4,15%); 4-methyl-1-ol-3-penten (3,93%); 1,4-benzodioksan-2,3-diyldiacetate (3,59%); (E) 2,6-dimethyl-1,6-diol-2,7-octadene (3,32%); 1[5(1-Hidroxyethylidene)-1,3-cyclopentadien-1-yl]-ethanone; (3,28); 2-(2,5-hexadiynyloxy)tetrahydro-2H-pyran (3,08%); 3,7-dimethyl-1,6-octadiene (3,03%); 2-methyl-2-ol-4-penten (2,52%); 3-methyl-1-ol-4-penten (2,51%); 4,8-dimethyl-4-ol-1,7-nonadien (1,85%). Testing Akway using well diffusion method four bacteria, namely B. subtilis, E. coli, S. aureus, typhi, had Inhibition with strong to very category. inhibition oils bacteria each zones 25 mm, 16.5 34 22 mm.
