The natural resources from Indonesia that can be used as an adsorbent are natural zeolite which could adsorb water but less use in cooling application although it is in abundant amount. One of the cooling systems that use less energy is adsorption. The measurement considerations of adsorbent are surface are, pore size, Si/Al ratio, type of zeolite and hydrophilic characteristic. The material being tested in this research is natural zeolite from Yogyakarta and Cikembar, Indonesia. This research analyzes the characteristic of the adsorbent including the BET surface area, pore volume, structural or morphologies characterization, and element composition from each natural zeolite. The result of this study showed that the BET surface area and pore volume of natural zeolite from Yogyakarta are one third smaller than Cikembar, but it has more hydrophilic of Si/Al ratio. Whereas the result of selectivity study between the two prove that both zeolite has better selectivity in each area that can be improve with post treatment or modification.
