This research deals with carbon electrodes made from date palm midrib biomass by varying physical activation temperatures of 700°C, 800°C, and 900°C with sample codes PK-700, PK-800, and PK-900. Electrodes are made with several stages such as pre-carbonization, chemical activation with KOH activators, carbonization at 600 °C with N2 and physical activation with CO2 . The highest density value was found in the PK-800 sample with a large shrinkage of 33.97%. The physical characterization of carbon electrodes using Fourier Transform Infrared Spectroscopy showed a high level of carbon purity due to the presence of the -C≡C- function group. X-ray diffraction analysis produces an amorphous structure with two wide peaks at angles of 2θ angles of 23° and 44° at scattering fields (002) and (100), with the lowest La and Lc highest in PK-800 samples at 5.205 nm and 10.330 nm. Analysis of surface morphology using the Electron Scanning Microscope showed that PK-800 samples produced more mesoporous than PK-700 and PK-900 samples. X-ray Dispersion Energy analysis depicted that the PK-800 sample produced the largest percentage of carbon at 90.16%. The N2 Adsorption Isotherm analysis describes that the PK-800 sample produces a surface area of 634,345 m²g-1.Supercapacitors with different samples were tested by using Cyclic Voltammetry and Galvanostatic Charge Discharge, providing spesific capacitances between PK-700, PK-800, and PK-900. The best sample is PK-800 with the largest spesific capacitance value of 213.80 Fg-1 for Cyclic Voltammetry and 227.84 Fg-1 for Galvanostatic Charge Discharge. The devices figure out good current stabilities with energy density of 10.42 Wh Kg-1 and power density of 133.33 W Kg-1.
