Cation exchangeable capacity (CEC) of zeolite could be determined not only based on SNI 13-3494 1994, but also Permentan No. 02/Pert/HK060/2/2006. Procedure of CEC determination based on SNI 13-3494 1994 and Permentan No. 02/Pert/HK060/2/2006 were not the same, so that CEC of zeolite from one sample of zeolite which is determined with both procedure could be different, and its CEC will definitely different. Generally, CEC of zeolite which is determined based on Permentan No. 02/Pert/HK060/2/2006 lower compare to SNI 13-3494 1994. Possible sources of error in these steps include the following: (1) in the saturation step, neither narrow ratios nor wide ratios between zeolite and ammonium acetate solution will be influential to the amount more or less ion NH4+to enter the exchange sites, and duration of percolation, (2) the washing step, to remove ion NH4+ excess on the exchange sites with etanol 96%, (3) ion NH4+ cation exchange with NaCl or KCl. The results of this study have been found that CEC zeolite sample No. 13, 15, 19, and 21 were 83, 94, 95, and 94 cmol(+) kg-1 respectively were greater than Permentan No. 02/Pert/HK.060/2/2006 (80 cmol(+) kg-1). CEC Zeolite Agro 2000 SNI 13-3496-1994 always high value, but in the saturation step, the washing step and removal ion NH4+ excess on the exchange sites with etanol 96%, (3) ion NH4+ cation exchange with NaCl or KCl were constitute a critical steps for CEC determination. CEC zeolite SNI 13-3496-1994 be suggested to revised, and CEC procedure either for soil conditioner for rehabilitation soil degradation or industry must be the same procedure.
