Wonosobo landfill leachate contains BOD of 290 mg/liter and the COD of 840 mg/liter and whey contains BOD of 5.455 mg/liter and COD of 2.350 mg/liter which is if discharged into the environment without any treatment would potentially reduce the quality of the environment. Agriculture has reached a critical stage, farmers have to spend a very high cost for crop production while fertilization did not experience significant improvement. If the soil that already in critical conditions is continue to be given the over composition of chemical fertilizer, will accelerate soil saturation and it will cause the soil become not productive anymore. The purpose of this study is to make the composition of the POC product mixture of leachate and whey to determine the composition of the POC that has closer to the required criteria by management of agricultural Spinacia farm and to examine the effectiveness of POC from the leachate and whey that applied on the Spinacia plants. POC product that was created expected to fulfill the standards and increase agricultural production of Spinacia by observing the increasing value of REA on standard treatment. The materials used for creating this POC is a landfill leachate and whey taken from Bumiroso Village, Watumalang by using modeling tools submerged biofilter and Spinacia plants in Batur village, Dieng, Wonosobo. This study uses 5 (five) composition of mixture of leachate and whey for creating the POC respectively 90% and 10% (POC1)
