    Corncob is a kind of side product on agricultural industry that exists in large amount from corn processing. Corncob predominantly consists of hemicellulose (36%), lignin (6%), and cellulose (41%). The cellulose content in corncob can be used as an adsorbent. In order to utilize corncob as an adsorbent its adsorption the ability need to be tested to potassium, sodium, sulfide, and sulfate in leachhate at Muara Fajar waste disposal not only as corncob powder form but also in char form. An atomic Absorbtion Spectrophotometer (AAS) was used to determine the content of potassium and sodium, while spectrophotometer of UV-Vis was used for sulfide and sulfate contents. Result showed that adsorption ability of corncob powder for potassium and sodium was higher than its char form (1,14 mg/g; 17,58 mg/g; and 1,095 mg/g; 16,85 mg/g). While the adsorption ability of corncob powder for sulfide and sulfate was lower than its char form (0,190 mg/g; 5,531 mg/g; 0,268 mg/g and 9,025 mg/g). According to paired t test method (p = 0,05), it showed that corncob and its char have effectiveness to adsorp sodium, potassium, sulfide and sulfate in leachete from Muara Fajar waste disposal
