<![CDATA[Land degradation can be caused by environmental pollution from heavy metals, and final processing sites have the potential to be contaminated with heavy metals, particularly lead (Pb) from waste. Lead (Pb), even at low concentrations, is hazardous to health, making remediation efforts very important. Stabilization using compost as a soil amendment is one of the remediation techniques. This study aims to determine the effect of various compositions of used maggot compost on lead remediation in soil from the Piyungan landfill. The study used a quantitative method with a Quasi-Experimental Pre Test–Post Test With Control Group design. There were 4 treatment groups with ratios of used maggot compost (A=40%, B=50%, C=60%, Control=0%). Remediation was carried out for 30 days. The results showed that in treatment group A, there was a decrease in lead of 46.19%, while in treatment groups B and C, there was an increase in lead (Pb) of 74.40% and 92.49%, respectively. However, the control group experienced a lead decrease of 11.22%. The concentration of 40% composted maggot residue had the most significant effect on lead (Pb) remediation. The increase in lead levels in some treatments was influenced by soil sample collection, pH fluctuations, temperature, and humidity]]>
