Hydrogen as the most cleanest energy source promise polutant free combustion. However, hydrogen production process still have negative impact on environment. Water electrolysis as one of hydrogen production process leave toxical gas residue and if the catalyst used in the process is metal catalyst it will leave metal waste which have potential to pollute soil and water. Curcumin as polyphenol antioxidant have potential as electrocatalytic agent due to its electron donor behavior. Curcumin loaded aluminum electrode coated by mechanical coating technique using water as solvent perform better as electrode compared to non-coated electrode. Curcumin coated cathode, anode and both electrode produce more hydrogen in shorter time than non-coated electrode. Curcumin electron donor increase the current density flows through the electrodes which is lift up the efficiency of water electrolysis process.
