Abstract: Chemical oxygen demand(COD) was the main characteristic in analyzed the quality of wastewater and leachate. Soluble COD(SCOD) and particulate COD(PCOD) previously determined by physico-chemical methods such as i) coagulation-flocculation ii) filtration. These meth-ods widely used in wastewater treatment. However, research on COD fraction for leachate is limited. This study aims to analyzed and de-termine the efficient method for PCOD and SCOD in mature leachate from semi-aerobic landfill. Three methods were applied in this re-search to compare the significant features of the three methods. Method 1(M1) and Method 3(M3) were applied from previous studies on COD fraction in wastewater. Modified method with optimum dosage of zinc sulphate known as Method 2(M2) was investigated in evaluate the correlation between COD particulate and coagulant. The result showed that PCOD in M2 is dominant (38.54%) due to the optimum dosage of coagulant while PCOD for M1 and M3 showed the results (M1=27.00%; M2=27.58%), respectively. In conclusion, the results of this study validate that M1, M2 and M3 in determine PCOD in wastewater and leachate. Effect of optimum dosage in M2 was consid-ered as new finding. Further research on COD fractions of leachate should be investigated to identify the appropriate treatment for mature leachate.
