Abstract
The increment of Songket popularity as the traditional fabric from South Sumatra increases the production of Songket and the wastewater produced during the dying process. The dying process produces the reddish wastewater, and if it is disposed of directly into the environment, it will have a negative impact on the waters. The wastewater treatment of this reddish liquid is by electrocoagulation method. Electrocoagulation method is contaminants removal by electrical and chemical treatment system. The electrocoagulation method in this research was conducted in a batch where the wastewater was treated using 16.5 x 7.0 x 0.2 cm aluminum electrode. The parameters varied were the current density and processing time to determine the pH value, color intensity, BOD5, COD, TSS, and phenol levels. The optimum condition obtained from this study at a current density of 25 A/m2 with a processing time of 160 minutes. The effectiveness of Songket wastewater electrocoagulation was 67.28% for TSS, 54.13% for BOD5, 63.64% for COD, color intensity 79.21% and phenol content of 74.93% respectively. The result has fulfilled the quality standard of textile industry wastewater treatment.

The electrocoagulation method can be used to treat songket industry wastewater and has several advantages compared to the coagulation method using chemicals [7], Electrocoagulation is the process of clumping and deposition of fine particles contained in water using electrical energy
A series of electrocoagulation devices are used consisting of aluminum electrodes, regulators, digital multimeters, and anode and cathode connecting cables
Summary
The liquid waste of the songket industry has become a major problem in controlling the environmental impact of the textile industry. The electrocoagulation method can be used to treat songket industry wastewater and has several advantages compared to the coagulation method using chemicals [7], Electrocoagulation is the process of clumping and deposition of fine particles contained in water using electrical energy. If in one electrolyte solution two electrodes are placed the electrode is flowed by a direct current of electricity an electrochemical process will occur in the form of electrolyte decomposition symptoms, i.e., positive ions (cations) move to the cathode and receive electrons reduced and negative ions move to the anode and give up the oxidized electron, so that later it will form a floc which is able to bind contaminants and particles in the waste [9]. A similar process was carried out in Brittain in 1956, only the anode used was iron and used to treat river water [11]
