Palm fruit fiber is also a plentiful waste but has not been used optimally. The ability of the palm fruit fiber and palm fruit fiber charcoal in removing Fe, Ca, Cl and organic compounds was investigated from leachate in TPA Muara Fajar Pekanbaru. Palm fruit fiber can be applied as adsorben because it contains 28.28% cellulose and 27.86% lignin. The concentration of iron was analyzed by AAS. calcium and organic compounds were analyzed with titrimetry method, and chloride was analyzed by argentometry method. The result showed that adsorption capacity of the palm fruit fiber for iron was 0.1035 mg/g, calcium 23.5427 mg/g, chloride 0.3402 mg/g and organic compounds 0.8848 mg/g. The adsorption capacity of the palm fruit fiber charcoal for iron was 0.0429 mg/g, calcium 36.2011 mg/g, chloride 0.5108 mg/g, and organic compounds 0.9500 mg/g. The efficiency percentage of the palm fruit fiber were found to be 29.36% to iron, 35.22% to calcium, 24.99% chloride and 56.00% to organic compounds. Whereas the efficiency percentage of the palm fruit fiber charcoal were 12.16% to iron, 54.15% to calcium, 37.52% to chloride and 60.13% to organic compounds. The result showed that the adsorption capacity and efficiency percentage of palm fruit fiber charcoal were greater than the palm fruit fiber. Based on statistical method (paired t test), it is found that palm fruit fiber and palm fruit fiber charcoal were effective to remove iron, calcium, and organic compounds but not for chlorideotheradsorption capacityefficiency percentage of adsorptionleachatepalm fruit fiberOther
