Abstract
Graphene merupakan material yang memiliki kristal
tersusun dari lembaran bidang karbon berbentuk heksagonal.
Graphene dapat dimanfaatkan sebagai bahan pembuatan
superkapasitor. Superkapasitor merupakan piranti yang dapat
menyimpan energi dan memberi energi.. Graphene merupakan
material yang sangat sesuai dan dapat diaplikasikan sebagai
elektroda superkapasitor. Penelitian ini bertujuan untuk
menganalisis pengaruh temperatur hidrotermal (190oC, 200oC,
dan 210oC) terhadap sifat kapasitif superkapasitor berbahan
graphene. Penelitian dimulai dengan mengoksidasi grafit
menjadi grafit oksida dengan metode Hummer. Setelah grafit
oksida disintesis maka dilanjutkan dengan mereduksi grafit
oksida menjadi graphene. Karakterisasi material menggunakan
X-Ray Diffraction (XRD), Scanning Electron Microschope
(SEM). Menentukan konduktifitas menggunakan Four Point
Probes (FPP). Menggunakan Cyclic Voltammetry (CV) untuk
mementukan kapasitansi relatif elektroda dengan
mendepositkan graphene ke dalam nickel foam dengan
menggunakan elektrolit Na2SO4.

Graphene is a material that has a crystal composed of
hexagonal sheets of carbon field. Graphene can be used as
materials for supercapacitors. Supercapacitor is a device that can
store energy and provide energy. Graphene is a material that is very
appropriate and applicable as supercapacitor electrodes. This study
aimed to analyze the influence of hydrothermal temperatures
(190oC, 200oC and 210oC) of the capacitive properties of graphenebased
supercapacitors. The research begins by oxidizing graphite
into graphite oxide with Hummer method. After the graphite oxide
synthesized then followed by the reduction of graphite oxide to
graphene. Material characterization using X-Ray Diffraction
(XRD), Scanning Electron Microschope (SEM). Determining
conductivity using the Four Point Probes (FPP). Using Cyclic
voltammetry (CV) to determine relative capacitance electrode by
depositing graphene into nickel foam using Na2SO4 electrolyte.
