| Summary: | 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)
