Kecombrang (Etlingera elatior) has been known for a long time by the Indonesian people and is used as an ornamental plant, vegetable, food flavoring, and traditional medicine. This study aims to determine the shelf life of the powder of kecombrang flower, stem and leaves packaged using aluminum foil and calculated using the acceleration method based on the critical moisture content approach. This study uses an experimental method. The parameters measured in this study were initial moisture content, critical moisture content, and equilibrium moisture content to obtain the correct isothermic sorption curve. Then other parameters that need to be considered in determining shelf life are the area of ​​the packaging, the weight of the packaging solids, the pure vapor pressure, and the water vapor permeability of the packaging. packaging. Based on the results of calculations using the Labuza equation about shelf life, it is found that the shelf life of kecombrang flower powder is 27 months, kecombrang stem powder is 30 months, and kecombrang leaf powder is 25 months.
