PENGARUH DAYA MICROWAVE TERHADAP PENINGKATAN RENDEMEN MINYAK NILAM (POGOSTEMON CABLIN BENTH) DENGAN DESTILASI STEAM – AIR MENGGUNAKAN GELOMBANG MIKRO

Abstract

Patchouli oil is one of the essential oils. To optimize the potential of essential oil, it is necessary to make efforts to raisethe rendement. One way is to improve the distillation technique and the operating distillation process which is able toproduce higher rendement. This research was conducted using steam-hydro distillation method by microwave withvariation of microwave power to the rendement. The ratio of raw material - water used were 1:1 (m / v) and powervariations were 100, 264, 400, 600, and 800 Watt. The weight of patchouli leaves and stem is 100 gram and put into thedistillation flask, then water is added by 100 mL, after which the steam was flowed into the distillation gourd of thesteam generator with the flow rate of 5 ml/min, then the microwave power was adjusted according to the specifiedvariables. Based on the research result, the highest rendement of 2.47% was obtained with the microwave power of 800Watt. The quality of the rendement has met SNI 06-2388-2006.
