N2 - Traditional gold mining activity is one of the source of mercury contamination. Total mercury concentration around the tailing ponds in Kulon Progo ranged from 0.30 to 22.51 mg/kg, which the exceeded the quality standard values set by the government of Indonesia No. 101 of 2014 which is 0.3 mg/kg. One method that can be applied is stabilization/solidification (S/S). This study aims to determine the optimum composition of Portland cement and tras soil used in S/S with contaminated soil. The study at first step, Portland cement and tras soil compositions was used by variations of the weight value of 100: 0, 90:10, 80:20, 70:30, 60:40, 50:50, 40:60, 30:70, 20:80, and 10:90. At second step, contaminated-soil samples were added into optimum from first step, with a variation composition of binder: soil iare 50:50, 40:60, 30:70, 20:80, and 10:90. Toxicity Characteristic Leaching Procedure was applied based on US EPA method 1311. First test result in optimum composition of Portland cement: tras soil (10:90), with the compressive test value of 96 kg/cm2. The second result of compressive test values of binder: contaminated soil (10:90) was 6 kg/cm2 is with mercury concentrations in the TCLP test of 0.0011 mg/L. The result of compressive test met the quality standards of US EPA for the management of contaminated soil at 3.5 kg/cm2. The result of TCLP test met the quality standards for products of S/S in accordance with Government Regulation 101 Year 2014 at 0.05 mg/L.
