The vigorous combination of waste in landfill recognized as potential hazard source, but one distinctive problem associated with landfill is leachate. Zeolite is well known as good adsorbent but the cost is relatively high. Meanwhile, feldspar is the most abundant mineral group in the world, forming around 60% of the earth’s crust. Due to its availability, feldspar becomes one of low cost materials. The combination of feldspar and zeolite are believed to produce inexpensive and suitable composite to treat leachate. The experiment carried out in a series of 250 mL conical flask with varied amount of composite ratio. It shaken for 5 hours with 200 rpm at pH 7. The optimum ratio of feldspar and zeolite chosen is 1:1. The value of the removal percentage of COD and NH3-N is 49% and 45% respectively and the uptake capacity for both contaminant is 50.14 mg/g and 8.06mg/g respectively. The presence of low cost material like feldspar in the composite has help reduce treatment cost and also help enhance the adsorption capacity.
