N2 - Cyclic voltammetry has been successfully analyzed from a diluted deep eutectic solvent (DDES) electrolyte for recovery printed circuit boards (PCB) containing 17.91% copper. The raw material sample is made through the dismantling stage until the grinding and then sieved to 80 mesh size for testing samples. Temperature variations are used to increase the surface area of the electrodes. The temperature variations used were 40C, 50C, and 60C. The cyclic voltammetric measurement method was carried out using the potentiostat / galvanostat autolab PGSTAT302N connected to a computer with NOVA 1.11 software and a DC power source used for electrolysis with a scan rate of 10 mV / s. From the measurement results, it was found that the largest capacitance value was at 60C with an oxidation peak of 1.15 A. with a current efficiency of 99.83%. Additional testing was also carried out using SEM-EDX to see the morphological surface of the cathode used.
