Abstrak : Abstract: Degradation of glycerol was carried out by microwave heating and hydrotermal process in temperature range of 100-200oC, in power range of 200-500 Watt and in reaction time range of 2-60 minutes. The effect of temperature, power, reaction time and using activated carbon as catalyst was investigated. As a result, the rate of acetaldehyde formation using microwave heating with activated carbon was higher than the hydrothermal treatment and microwave heating without a catalyst, but the rate of acrolein formation acrolein was lower than hydrothermal treatment and microwave heating without a catalyst. The constant rate of glycerol degradation were 0.012, 0.009, and 0.008 for microwave heating using activated carbon catalyst, hydrothermal, and microwave heating without catalyst. Keywords: Degradation, glycerol, microwave, hydrothermal, activated carbon Abstrak: Degradasi gliserol dilakukan dengan pemanasan microwave dan proses hidrotermal
