The water of the Citarum river in West Java is used as a water source for three hydropower plants, and some industries operate along the river area. Besides industries, the Citarum river also accommodates domestic and livestock waste. These lead to very high-level pollution in the Citarum river, especially organic and heavy metal waste. One method that can reduce simultaneously organic and heavy metals in water is electrocoagulation. The purpose of the research is to determine the influence of initial pH or pHi on the removal of total suspended solids, total organic pollutants, and nickel ion from Citarum water using aluminum as a cathode and an iron metal as an anode in the electrocoagulation method. During the electrocoagulation process, current density, electrode distance, stirring speed, DC supply voltage, and temperature were kept constant at 118 Am -2 , 2 cm, 100 rpm, 18.3 V, and 26-27 0 C respectively. The nickel-metal ion concentration is determined using Atomic Absorbance Spectrometry (AAS), total suspended solids as TDS by pH/EC/TDS/ 0 C meter, and organic pollutants as TOC by permanganometic titration. It is found that Ni removal is almost 100% after 10 minutes electrocoagulation process at pHi 3, 5 minutes at pHi 5 and 9, and 60 minutes at pHi 7.5. The Maximum total suspended solids, and total organic pollutants removal was obtained after 60 minutes electrocoagulation process. The finest total solid suspended and total organic pollutants removal achieved at pHi 3 are 40 and 84%, respectively. The kinetics of total organic pollutants and total suspended solids removal is suggested obeying the second-order and Lagergren's 2nd order equation, respectively. So, It suggests that the total suspended solids are removed from Citarum river water through an adsorption mechanism.
