xiv, 56 p. : ill. (some col.) ; 30 cm + 1 computer disc The objective of this research is to extract zingiber aromaticum essential oil by using a microwave assisted extraction (MAE) with solvent. Rhizome of zingiber aromaticum accumulates large amount of essential oil that contains bioactive sesquiterpenoid zerumbone which is widely used in medicine sectors. This research has focused on the influence of microwave power (500 Watt) at various natures of solvents and times of the extraction of zingiber aromaticum essential oil. Four types of solvents are used in this research which is ethanol, methanol, hexane and water. In this research, the methods of drying, grinding, extraction, separation and analysis are used and the sample is separated from solvents by using a rotary evaporator to get the essential oil. The sample was analyzed by using a GC-MS to identify the component of zingiber aromaticum oil. The optimum yield of zerumbone is 17.72 % at microwave power of 500 W and 10 minutes of extraction by using methanol as solvent.-Author- specialized S Muhammad Al-Hafiz Muhammad Project paper (Bachelor of Chemical Engineering) -- Universiti Malaysia Pahang - 2009 Bibliography : p. 30-34 Essences and essential oils Extraction (Chemistry) Ginger THE0004087(Local) UMP 100219 20251114204423.0 vtls000045149
