SUMMARY
Industrial development in Indonesia tends to increase every year, including the metal coating industry. The amount of waste that is disposed of without going through first processing can increase the number of pollution in the environment. Electrocoagulation is a method that has been successfully used for the treatment of metal plating waste. The principle of the electrocoagulation method is based on oxidation and reduction reactions. This study aims to analyze the reduction of metal levels in electroplating waste using the electrocoagulation method. This study used variations in voltage, length of time for electrocoagulation and speed of stirring in electroplating wastewater treatment. The electrocoagulation filtrate was analyzed using Atomic Absorption Spectrophotometer. The flocculants produced from the electrocoagulation process were analyzed using Scanning Electron Microscopy-Energy Dispersive X-Ray Spectroscopy (SEM-EDS) to analyze the morphology of the precipitate and the elements contained in the flocculants. The voltage of 10 volts has a chromium metal content value of 1.9 mg/L with a metal reduction percentage of 70.31%. The electrocoagulation time of 240 minutes has a chromium metal content of 0.033 mg/L with a metal reduction percentage of 99.48%. The stirring speed of 150 rpm has a chromium content of 0.1 mg/L with a metal reduction percentage of 98.43%. The stirring speed of 150 rpm has a large agglomerate morphology. The results of elemental analysis using Energy Dispersive X-Ray (EDS) showed that the flocculant contained an elemental carbon (C) of 5.17%. The elemental content of oxygen (O) is 50.95%. The elemental content of aluminum (Al) is 28.78%. The elemental content of chromium (Cr) is 12.15%. The use of the electrocoagulation method was quite effective in reducing pollution due to electroplating waste.
