Abstract
Di era globalisasi ini, banyak piranti elektronik yang
membutuhkan kapasitor, seperti komputer. Namun, masih
terdapat kekurangan pada sifat – sifatnya sehingga masih perlu
dikembangkan. Kapasitor adalah perangkat elektronik yang
dapat menyimpan dan memberikan energi, salah satu
pengembangannya adalah superkapasitor. Salah satu tipenya
adalah Electrical Double Layer Capacitor atau EDLC.
Pengembangan yang umum dilakukan adalah penggunaan
graphene dalam aplikasi EDLC. Alasan menggunakan
graphene adalah sifat konduktifitas listrik dan luas permukaan
aktif yang tinggi yang dimiliki material graphene. Dengan
tahapan reduksi, pereduksian grafit oksida, sehingga menjadi
graphene diharapkan mampu menghasilkan sifat konduktifitas
listrik yang baik, sehingga penelitian ini bertujuan untuk
mengetahui pengaruh reduktor Ferrous (Fe) pada graphene
terhadap sifat kelistrikannya dan struktur graphene. Metode
Hummer yang dimodifikasi diikuti dengan proses
hydrothermal digunakan untuk mensintesis reduced Graphene
Oxide (rGO). Penelitian ini menggunakan Iron Powder 99%
sebagai media reduktor dengan variasi massa 0,68 gr, 1,36 gr,
2,04 gr. Material yang disintesis dikarakterisasi dengan
menggunakan XRD, SEM-EDX, FTIR, FPP, dan CV. Sifat
kapasitif elektroda diukur dengan melakukan uji CV dengan
rentang scan rate 5, 10, 50 dan 100 mV/s. Hasil Penelitian ini
menunjukan bahwa kapasitansi spesifik sebesar 172 F/g pada
massa reduktor 0,68 gr Fe dengan larutan Na2SO4 1M.
=============================================================================================================
In this era of globalization, many electronic devices that
require capacitors, such as computers. However, there are still
deficiencies in its properties so it still needs to be developed.
Capacitor is an electronic device that can store and energize, one
of the development is superkapasitor. One type is Electrical
Double Layer Capacitor or EDLC. A common development is the
use of graphene in EDLC applications. The reason for using
graphene is the electrical conductivity properties and the high
active surface area that graphene material possesses. By reducting
graphite oxide, which would be graphene, is expected to produce
good electrical conductivity properties,. Therefore, the research
aims to determine the effect of Ferrous (Fe) reductor on graphene
structure and electrical properties. The modified hummer method
was followed by a dried process was used to synthesize reduced
graphene oxide (rGO). This research uses 99% Iron powder as a
reducing medium as mass variation of 0.68 gr, 1.36 gr, 2.04 gr.
The synthesized material was characterized using XRD, SEMEDX,
FTIR, FPP, and CV. The capacitive properties of the
electrode were measured by performing a CV test with a scan rate
range of 5, 10, 50 and 100 mV / s. The results of this study
showed that the specific capacitance of 172 F / g in the reduction
mass of 0.68 gr Fe with 1M Na2SO4 solution.
