    Palm fruit fiber is one of the solid waste which is derived from the processing of palm oil industry. 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 chloride

    DAYA SERAP SABUT KELAPA (Cocos nucifera) UNTUK REMEDIASI TEMBAGA, KOBAL, SIANIDA DAN KESADAHAN PADA AIR LINDI TPA MUARA FAJAR PEKANBARU

    The FWD (TPA) Muara Fajar is the final waste disposal for the city of Pekanbaru. It contains varied chemical elements that may raise environment pollution. It can be happened because the decomposed waste produces leachate. Leachate contents organic and inorganic compounds. The inorganic compounds that can be found in the leachate are like copper, cobalt, cyanide ions and total hardness. This study was conducted in order to know adsorption capacity of coconut fiber and coconut fiber charcoal to remove copper, cobalt, cyanide ions and total hardness from leachate of FWD Muara Fajar. Leachate sampling is done at the lechate inlet. The result showed that adsorption capacity of the coconut fiber for copper, cobalt, cyanide ions and total hardness are 0,12 mg/g, 0,011 mg/g, 0,2 mg/g and 272 mg/g, respectively. Whereas the adsorption capacity of coconut fiber charcoal for copper, cobalt, cyanide ions and total hardness are 0,123 mg/g, 0,0114 mg/g, 0,483 mg/g and 300,96 mg/g, respectively. The data was analized using statistical method (paired t test). The coconut fiber and coconut fiber charcoal show significant difference for removing copper and total hardness. The coconut fiber has significant different for removing cobalt whereas coconut fiber charcoal does not have significant difference for removing cobalt. Both of coconut fiber and coconut fiber charcoal for removing cyanide ions from leachate TPA Muara Fajar is not significantly different
