Pembuatan Dan Karakterisasi Karbon Aktif Dari Limbah Filter Rokok Berdasarkan Variasi Persentase Aktivator Koh

---

Main goal of this current research is to produce activated carbon from waste
cigarette filter sampoerna as supercapacitor electrodes. The process synthesis of
the activated carbon utilized chemical activation by using Potassium Hydroxide
(KOH) as activator in which the mass ratio of the sample and KOH was 1:2, 1:3,
and 1:4. The samples were chemically activated then flowed by N2 gas at a
temperature of 600°C during an interval of 8-9 hours. Characterization of physical
properties and electrochemical properties such as scanning electron microscopy
(SEM), energy dispersive x-ray (EDS), x-ray diffraction (XRD),
Thermogravimetry Analyzer (TGA), Braunauer-Emmeltt-Teller (BET) and cyclic
voltammetry (CV ) have been used in this study. Optimal conditions of mass ratio
of sample and KOH was 1:4 to produce density of 1.094 g/cm3, greater porosity
so able to enlarge the surface area of activated carbon at 471.764 m2/g. The results
of TGA analysis showed a maximum reduction in mass at a temperature of 324°C.
Surface morphology showed gread number of open pores and the spread of spot
TiO2 nanoparticles on the surface of carbon. The content of the carbon and
oxygen generated in the atomic constituents was 95.86% and 4.14%. XRD pattern
of the sample showed two peaks in carbon with respectively crystal orientation
(002) and (100) at an angle 2θ of about 24° and 44° and the sharp reflection peak
(101) with maximum intensity of TiO2 nanoparticles have a size of an average
crystal of 0.9154 nm. Electrochemical properties of Carbon electrode have been
measured using electrolyte H2SO4 of 1 M result in the potential interval of 0 to
0.5 V with a scan rate of 1 mV/s has a specific capacitance of respectively
electrode to sample mass ratio and KOH (1:2) and (1:4) was 7.14 F/g and 36.17
F/g.
Keywords: Waste cigarette filters, activated carbon, carbon electrodes, and
supercapacitors.
