Pembuatan Nanoserat Selulosa Tandan Kosong Kelapa Sawit (TKKS) dengan MnO2 dan Go (Grafena Oksida) sebagai Elektroda Superkapasitor

Abstract

Preparation of palm empty fruit bunch cellulose nanofibre with MnO2 and GO (Graphene Oxide) as supercapacitor electrodes has been carried out. The cellulose obtained was subjected to FT-IR test to determine the OH group. Preparation of cellulose nanostructures was carried out by ultrasonication method for 2 hours using ultrasonic homogenizer, PSA (Particle Size Analyzer) test was conducted to determine the size of cellulose nanofibre and the size of CNF obtained was 144.52 nm. SEM (Scanning Electron Microscopy) test to determine the morphology. Cellulose nanofibre obtained as much as 3 ml were then mixed with 50mg MnO2 and GO variations of 33%, and 50% stirred for 1 hour and then the mixture was smeared using a brush on aluminum foil measuring 2 x 1.5 cm. The electrode was then dried at 40℃ for 1 hour. The supercapacitor electrode can stick well to the aluminum foil and does not peel off. The supercapacitor electrode was tested with cyclic voltammetry (CV) and four point probe (FPP). The best capacitance was 45.305 F/g at 33% GO variation. The best electrical conductivity is found in the variation of 50 mg MnO2 and 50 mg GO with the value of GO50% is 5.9418 S/m. At 45.305 F/g capacitance has not met the standard said to be a supercasitor electrode because the capacitance value has not reached 100F/g.
