The Study Quality of Compost with The Utilization of Leachate Water in Landfill as A Bioactivator.

Abstract

Garbage can be a source of environmental pollution if its existence is not utilized and processed properly. The processing at the Final Processing Site (TPA) produces a residue in the form of leachate. The leachate comes from the waste degradation process which is known to contain nutrients, heavy metals, xenobiotics and organic matter. Therefore, it is necessary to use leachate at the Bandengan landfill located in Jepara Regency which is useful in composting organic waste. The process of making organic waste compost with the addition of leachate as a bio activator can effectively accelerate the compost maturation process and can reduce the C/N ratio, the percentage of sugar as a nutrient for bacteria, the process temperature and the size of the material. This study aims to determine the quality of the use of residues from waste management in the form of leachate and organic waste into compost that is safe for environmental media and agricultural media. The test samples were taken using purposive sampling at three locations, including: IPAL inlet channel, WWTP pond, outlet channel at the Leachate Security Installation (IPAL). The method that will be used in the utilization of organic waste into compost is the Open Windrow Method. Reviewing the quality of the compost, it was found that the optimum leachate for composting and safe for the soil as well as looking at the Germination Index (IP) came from the WWTP outlet channel. The Bandengan Jepara Wastewater Treatment Plant has a series of technologies to reduce the heavy metals contained in the leachate.
