Mount Merapi is one of volcano in the world that have high importance to be researched. It is caused by the volcano location adjacent with human civilitation that can be dangerous if the volcano erupt or other activity occure. Therefore mount Merapi observation is needed to reduce hazard caused by disaster. The deformation observation can be done with InSAR (Interferometric Synthetic Aperture Radar) method. InSAR is one of metodes to understanding deformation that used in some volcano deformation research. With this method there is using of fase differential from two SAR satelite image thus make interferogram that has topography of Earth, curvature of Earth, deformation, noise, atmosfer effect and orbit effect information. Deformation informaton can be obtained by reducing all of information in the interferogram except deformation information. Global DEM SRTM 3” is used in this researched to reduce topography efect with some series of DInSAR process. In this research, interferogram made from some pair of ALOS PALSAR to make DEM with better resolution than Global DEM SRTM 3”. This data would be used as comparison in DInSAR process. Result of comparison indicate that deformation map that obtained by using DEM made from SAR and Global DEM SRTM 3” has same deformation pattern but has different resolution and accuracy. Also from this research, there was inflation that occure in Mount Merapi before eruption and after eruption, inflation still ocured on Mount Merapi with lower activity than inflation before eruption.
