Natural resources carbonization doping using heavy atom is the common method to synthesize organic electrocatalyst for waste to hydrogen energy conversion. This study provides one-step solution to synthesize organic electrocatalyst using enzymatic protein of Lumbricus Rubellus . L,Rubellus extract and its combination with graphite flakes in powder form are tested as electrocatalyst for instant noodle wastewater electrolysis and pre-hydrolyzed instant noodle wastewater by direct mixing. Pre-hydrolysis has doubled the hydrogen production rate for each tested catalyst. Lumbricus Rubellus extract without graphite flake mix performs better in pre-hydrolyzed wastewater. Graphite flakes form polar substrates in pre-hydrolyzed wastewater. Positive substrates inhibit the hydrogen evolution reaction of pre-hydrolyzed wastewater by electron deposition. Negative substrate inactivates L,Rubellus protein due to competitive inhibition.
