    Alpinia malaccensis plants was one of essential oil source which has antimicrobial activity. Isolation of essential oil from Alpinia malaccensis was carried out with traditional hydrodistillation method and microwave method. Optimal conditions in the traditional method was 6 hours, while the optimal conditions in the microwave method were 100 oC, 600 W, and 90 minutes. Isolation of the essential oil from Alpinia malaccensis with traditional method produces higher yield (0.009%) compared to microwave method (0.002%). Compounds in the essential oil of Alpinia malaccensis stem identified by GC-MS. The main component of essential oil rod Alpinia malaccensis obtained by using hydrodistillation and microwave-assisted hydrodistillation is methyl cinnamic as much as 98.24% and 96.97% respectively. Essential oils rod hydrodistillation of Alpinia malaccensis from traditional hydrodistillation method and hydrodistillation microwave method was active as an antimicrobial agent.
