---

Biomass-based porous carbon electrodes have been widely used as a basic material for making supercapacitor cell electrodes, because its application can be applied in the long term, sustainable, renewable, easy to find and has economic value. This research used biomass melinjo fruit shell (CBM) with variations in the addition of melamine mass, namely 0, 0.1, 0.3, and 0.5 g as carbon electrodes for supercapacitor cells. The process of synthesizing supercapacitor cell electrodes is through several stages, a pre-carbonization at of 200°C, chemical activation using KOH, carbonization with N_2 gas at a temperature of 600°C and physical activation with CO_2 gas at a temperature of 800°C. The highest density shrinkage value is owned by the CBM-03 sample is 56.45%. X-Ray Diffraction analysis shows that there are two peaks at an angle of 2θ angles of 22º and 44º at scattering fields (002) and (100) which identify amorphous characteristics. Analysis Scanning Electron Microscopy showed the formation of porous carbon electrodes with nanofiber structure. Analysis Energy Dispersive X-Ray showed that the CBM-05 produced the largest percentage of carbon at 95.60% of the three samples. Adsorption-desorption N_2 analysis shows that the CBM-05 sample has the highest surface area at 470.96 m²/g. Fourier Transform Infra Red analysis showed that the active carbon of melinjo fruit shell contained the functional groups O-H, C≡C, and C=C. Electrochemical analysis of supercapacitor cells using the Cyclic Voltammetry and Galvanostatic Charge-Discharge methods with 1 M H_2 SO_4 electrolyte, shows the highest specific capacitance values were owned by the CBM-03 sample of 400 F/g and 97 F/g. In conclusion the biomass derived from melinjo fruit shell (CBM), which is underutilized and wasted, has the potential to use as a porous carbon electrode for high performance supercapacitor cell applications.
Keywords: melinjo fruit shell, carbon electrode, KOH, supercapacitor.
