In this research, geopolymer is obtained from fly ash coal-thermal power with various ratio of alkaline liquid and fly ash. Moreover, microwave energy in range of 100, 200 and 400 W is used. The results are indicated that the compressive strength is obtained from 5 to 7 MPa with energy 100W in range from 3 to 10 minutes. The geopolymerization can be improved with higher in microwave energy and curing time. Then, compressive strength is about 10 Mpa with energy 400W on 10 minutes curing
