Optimasi tegangan pada proses elektrokoagulasi penurunan kadar kromium dari filtrat hasil hidrolisis limbah padat industri penyamakan kulit telah dilakukan. Proses elektrokoagulasi dilakukan menggunakan elektroda Fe dengan variasi potensial (2 volt, 4 volt, 6 volt, 8 volt, dan 10 volt), waktu elektrokoagulasi  30 menit. Dari data hasil penelitian, diperoleh kadar kromium dalam filtrat hasil hidrolisis limbah padat industri penyamakan kulit sebesar 84,90 mg/L. Tegangan optimum proses elektrokoagulasi terjadi pada potensial 8 volt dengan presentase penurunan kromium dalam filtrate hasil hidrolisis sebesar 98,82%.
