Abstract
The microencapsulation of essential oil from rogo plant (Premna serratifolia L.) has been performed as an antibactery Escherichia coli. The purpose of this research is to know the component of composition, characteristic and test of essential oil activity of rogo and microencapsulation as antibactery E.coli. Rogo essential oil is obtained from isolation using steam-water distillation method with 0.63% rendamen. Characterization has been performed using Gas Chromatography-Mass Spectrometry (GC-MS) indicating that rogo isolated essential oil contains 4 main components such as eugenol (47.89%), eugenyl acetate (9.13%), massoil (29.78%) and cis-2-oxabicyclo, 4.4.0- decane (12.35%). The microencapsulation process of rogo essential oil is done using spray drying method with variation of rogo essential oil ratios: maltodextrin (1:10; 1:12; 1:14; 1:16; and 1:18) resulting in white sticky textured solid powder. The results of the rogo essential oil activity test showed that there was a decrease in concentration of 12.5%. While the result microencapsulated antibacterial activity test showed no difference from all variation concentration. The result of antibacterial activity test between rogo essential oil and microencapsulated results showed significant difference, the phase in the form of oil has greater antibacterial activity strength than the solid phase.
