Red ginger leaf waste (Zingiber Officinale Var Rubrum) has been successfully processed as an active carbon base material for supercapacitor electrodes. The process of making carbon electrodes starts from the preparation of the original material, drying, refining, chemical activation, integrated pyrolysis and neutralization. The focus of this research is on the chemical activator ZnCl2 which is used with different concentrations of (0.1 and 0.5) M. Activated carbon powder is printed using a press to produce carbon in the form of solid coins of uniform size. The optimization of the carbon element in the sample is carried out through a pyrolysis process at high temperature with a one-stage integrated technique. Where, carbonization in the N2 gas environment is carried out starting from room temperature 30°C up to 600°C followed by physical activation until the high temperature reaches 800°C in CO2 gas environment. Characterization of activated carbon samples from red ginger leaves begins with determining the amount of shrinkage that occurs in the pyrolysis process by measuring the mass, diameter and thickness of the carbon coins. Furthermore, the electrochemical properties were tested using two methods, namely cyclic voltammetry (CV) and galvanostatic charge-discharge (GCD) in a symmetrical two-electrode system. The electrochemical characterization was carried out under the influence of an aqueous electrolyte of 1M KOH and 1M Na2SO4 at a low potential window of 0-1 V. The optimum conditions of electrochemical properties were found in the red ginger leaf activated carbon sample with a ZnCl2 activator concentration of 0.5M for the electrolyte. KOH with a specific capacitance value of 115.9 F/g. while for electrolyte Na2SO4 found in ZnCl2 activator 0.1M with a value of 72 F/g. Through these results, red ginger leaves are known to have great potential as a base material for activated carbon electrodes to improve the performance of supercapacitors.

This Research has carried out on natural sand originating from the Rokan river, Riau Province by converting it into magnetic iron oxide nanoparticles to determine changes in magnetic properties and particle size. Natural sand samples of the Rokan river were separated between magnetic and non-magnetic particles using an iron sand separator (ISS). ISS products are further synthesized using ball milling and coprecipitation methods. 70-hour ball milling products, coprecipitation without ball milling and coprecipitation with 70-hour ball milling are then given NdFeB (neodymium iron boron) magnets to clean impurities containing non-magnetic elements. The results of this study showed that the highest magnetic acceptability value was obtained in coprecipitation products with ball milling, which was 12.9 × 10-2. This is because coprecipitation products have an abundant content of chemicals in the form of magnetic elements. Based on the results of chemical composition testing using X-ray flourescence (XRF) it was found that in coprecipitation products with ball milling there was 64.504% iron (Fe) content, while 70-hour ball milling products and coprecipitation without ball milling the percentage of Fe protection was 15.023% and 54.152%, respectively. Based on the results of the identification of the chemical composition in the sample, coprecipitation products with 70-hour ball milling have high magnetic induction values and magnetic suseptibility caused by the magnetic content in products such as Fe which are very high and non-magnetic content is very low such as Si compared to 70-hour ball milling products and coprecipitation products without ball milling.

Electrolytes have been generally recognized as one of the most important components in enhancing the electrochemical performance of supercapacitors. On the other hand, aqueous electrolytes are considered prime candidates for the development of the next generation of symmetric supercapacitors due to their low-cost, environmentally friendly, high ionic conductivity, fine ionic size, and high capacitance. Herein, the symmetrical supercapacitor of the sustainable porous carbon-based electrode material was confirmed through various aqueous electrolytes consisting of neutral, basic, and acidic Na2SO4, KOH, and H2SO4. Activated carbon is obtained from high potential biomass sources of cassava peel waste. Activated carbon synthesis was performed with a comprehensive approach in order to obtain abundant pore structure, high porosity, and improved wettability through a combination of high-temperature chemical and physical activation. in addition, the electrode material is designed to resemble a solid disc without the addition of a synthetic binder. The evaluation of the disc dimensions showed high porosity in the obtained activated carbon. Furthermore, the symmetrical supercapacitor of the optimized electrode material exhibit excellent specific capacitances of 112, 150, and 183 F g-1 at 1 mV s-1 in the electrolytes Na2SO4, KOH, and H2SO4, respectively. In addition, the highest rate capability of 70% was confirmed in the H2SO4 acid electrolyte. Moreover, their coulombic efficiency can be maintained around 89% with low equivalent series resistance 0.21-0.42 ?. Therefore, the activated carbon-based supercapacitor symmetric cell device from cassava peel shows high performance for developing high-performance supercapacitor applications with guaranteed stability in aqueous electrolytes.
