Abstract
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
