Plating process now has been widely used in the electronics industries for corrosion resistance purpose. One of favorable solution used in nickel-plating process is Watts Bath solution. After several duration of time, the used Watts Bath must be discarded. Due to high amount of nickel concentration inside the Watts Bath, it has been considered as a schedule waste and need a proper disposal process which is expensive. One of reliable methods to dispose and recover nickel from the Watts Bath is by using electrowinning process. The aims of this study are to determine concentration of Watts Bath and to optimize the electrowinning process by using Box-Bhenken Design from Simulated Watts Bath of Electronics Industrial Waste. During this study, the electrolyte concentration, potential applied and contact time were optimized, and the surface morphology of nickel deposited also has been studied. From the result, the concentration of Watts Bath solution is 153 g/L and the removal of 75.04% was obtained under optimized condition which were 0.4 M of electrolyte concentration, 0.4 V of potential applied, and 60 min of contact time.
