      "abstract": "ex liquid waste containing organic compounds, synthetic dyes,\r\nphenol, ammonia, sulfide, and oil and grease that may severely deteriorate aquatic ecosystems if left untreated.\r\nThis study aimed to evaluate the performance of a multistage electrocoagulation-based wastewater treatment\r\nplant (WWTP) in reducing pollutant parameters of batik wastewater to comply with the quality standards of\r\nPERMENLH\/BPLH No. 12 of 2025. The WWTP, with a capacity of 100 L\/day, was operated using two seriesconnected electrocoagulation reactors equipped with six aluminum electrodes spaced 4 cm apart, powered by\r\ndirect current at 24 V\/2–6 A, with an ascending flow rate of 150 mL\/min. Wastewater was pre-diluted at ratios\r\nof 2x, 3x, and 4x prior to entering the reactor. Eleven water quality parameters were analyzed following\r\napplicable SNI methods. The results demonstrated that a 3x dilution ratio yielded the most optimal operational\r\ncondition, achieving removal efficiencies of 87.11% for COD, 86.97% for BOD, 79.24% for phenol, 66.62%\r\nfor total ammonia, 61.32% for sulfide, 79.35% for color, and 68.55% for electrical conductivity, all of which\r\nmet the prescribed standards. However, TSS (109 mg\/L), oil and grease (10.4 mg\/L), and pH (9.69) remained\r\nabove permissible limits.\r\nKeywords: Batik wastewater, electrocoagulation, wastewater treatment plant\r\n_________________________________________________________________________",
