Analisis Potensi Tanaman Daun Pala Sebagai Sumber Karbon Nanofiber Untuk Aplikasi Super kapasitor

---

The potential of nutmeg leaves is known to contain natural compounds and can be used as a basic source of porous activated carbon for supercapacitor electrode materials. This research aims to determine the effect of chemical activation on the physical and electrochemical properties of supercapacitors. Nutmeg leave biomass is carbon source for electrode material as supercapacitor applications through a pre-carbonization stage, then chemical activation using a KOH activator is applied in three concentration variations including 0,3 M, 0,5 M, and 0,7 M. Samples were simplified for analysis by coding them as DP 0,3, 0,5, and 0,7. The next process is carbonization using N2 gas in temperature 600°C and physical activation using CO2 gas at a temperature of 850°C. The activated carbon electrode on the DP 0,5 sample obtained shows a nanofiber structure with a combination of hierarchical pores. DP 0.5 activated carbon has produced a carbon content of 61,14% with clearly confirmed amorphous properties. Measurements of N2 gas absorption show that DP 0,5 activated carbon has a surface area of 418,39 m2/g. The electrochemical properties of the supercapacitor cell are reviewed through a two-electrode system in 1 M H2SO4 electrolyte. The optimum activated carbon sample obtained was DP 0,5, which confirmed the high specific capacitance reaching 235,14 F/g and the maximum energy density was obtained at 32,01 Wh/kg at an optimum power density of 219,34 W/kg. The great potential of nutmeg leaves as a source of activated carbon with a nanofiber structure shows that it can improve the performance of supercapacitor electrochemical energy storage devices.
Keywords: nutmeg leaves, nanofiber, supercapacitor, carbon electrode, specific capacitance.
