Kinerja Ipal Berbasis Elektrokoagulasi Bertahap Pada Pengolahan air Limbah Batik Asal Desa Parakan Jaya Kecamatan Kemang Bogor
ex liquid waste containing organic compounds, synthetic dyes, phenol, ammonia, sulfide, and oil and grease that may severely deteriorate aquatic ecosystems if left untreated. This study aimed to evaluate the performance of a multistage electrocoagulation-based wastewater treatment plant (WWTP) in reducing pollutant parameters of batik wastewater to comply with the quality standards of PERMENLH/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 direct current at 24 V/2–6 A, with an ascending flow rate of 150 mL/min. Wastewater was pre-diluted at ratios of 2x, 3x, and 4x prior to entering the reactor. Eleven water quality parameters were analyzed following applicable SNI methods. The results demonstrated that a 3x dilution ratio yielded the most optimal operational condition, achieving removal efficiencies of 87.11% for COD, 86.97% for BOD, 79.24% for phenol, 66.62% for total ammonia, 61.32% for sulfide, 79.35% for color, and 68.55% for electrical conductivity, all of which met the prescribed standards. However, TSS (109 mg/L), oil and grease (10.4 mg/L), and pH (9.69) remained above permissible limits.
