The\r\nprocessing process is carried out using an electrocoagulation reactor measuring 5900 mL equipped with 4\r\naluminum electrodes spaced 4 cm apart. The electrode is conducted with a direct electric current of 2-8 A at a\r\nvoltage of 24 volts. The test results are compared with the standard standard of PERMENLH\/BPLH No. 12 of\r\n2025. The results of the study showed that at 2x EC II dilution, it was the most optimal condition. Under this\r\ncondition, the total ammonia allowance reached 83.23%, phenol 67.94%, sulfide 100%, COD 89.90%, BOD\r\n87.92%, TSS 81.76%, DHL 77.45%, color scale (Pt-Co) 93.91%, and DO increased by 38.18%.\r\nKeywords: total ammonia, electrocoagulation, phenol, sulfide, batik wastewater",
