The more commonly used method for making synthetic zeolite from kaolin is hydrothermal method. This research tested a sol-gel method in processing synthetic zeolit  using kaolin as the basic ingrediant. The synthetic  zeolite  derived from the sol-gel method was then characterized using X-ray Difractometer and Scanning Electron Microscope, which found resulting products zeolite-A, zeolite Y and sodalite. The adsorption ability of the synthetic zeolites was tested using Cu(II) and methylene blue.  Functionalization of the synthetic zeolites by 3-(trimetoksisilil)-1-propantiol was  done to increase adsorption capacity. Zeolite A modified by 3-(trimetoksisilil)-1-propantiol  had the greater capacity to adsorb methylene blue at 30.11 mg/g. The adsorption isotherms of all the synthetic zeolites approached the Langmuir form. The adsorption energy off all synthetic zeolites approached the chemical adsorption.
