Abstract
Kemajuan teknologi saat ini sangat berkembang dengan pesat di
berbagai bidang. Akan tetapi, seiring dengan berkembangnya
teknologi yang pesat, dibutuhkan suatu material baru yang dapat
memenuhi kebutuhan tesebut. Seperti suatu material yang
berukuran kecil dan ringan sifat yang baik. Material yang dapat
menjawab kebutuhan tersebut adalah graphene. Dalam penelitian
ini dilakukan sintesa graphene dengan menggunakan metode
hydrothermal. Grafit akan dioksidasi untuk menghasilkan grafit
oksida. Grafit oksida akan di ultrasonikasi selama 2 jam untuk
membentuk graphene oksida. Setelah itu akan direduksi
menggunakan serbuk Zn dengan variasi 0,8 gram, 1,6 gram, dan
2,4 gram. Kemudian graphene oksida yang telah direduksi
dipanaskan dengan menggunakan metode hydrothermal dengan
variasi temperatur 160
o
C, 180
o
C, 200
o
C agar terbentuk graphene
murni. Pengujian yang dilakukan pada penelitian ini adalah XRay
Diffraction (XRD), Fourier Transform Infrared
Spectroscopy (FTIR), Four Point Probe (FPP), Scanning
Electron Microscope (SEM), dan Thermo Gravimetric Analysis
(TGA). Hasil Penilitan didapatkan yaitu semakin meningkatnya
penambahan massa Zn sebagai reduktor akan mengakibatkan
morfologi permukaan pada graphene semakin tipis karena hasil
reduksi yang dihasilkan semakin baik. variasi terbaik adalah
massa Zn 2.4 gram dan temperatur hydrothermal 180
o
C dengan
konduktivitas elektrik terbaik sebesar 0.012526 S/cm
============================================================================================
Today, technology is growing rapidly in various fields. However,
along with the rapid development of technology need a new
material that can meet what technology need most. Such a
material that is small and light, but with a good electrical,
thermal and mechanical properties. That material is graphene. In
this research, graphene was synthesis using hydrothermal method
and use zinc as a reducing agent.Graphene was synthesized at
different temperatures and mass off Zn powder. X-ray diffraction
(XRD) analysis confirmed that graphene can be made by
hydrothermal process with Zn powder as reducing agent. As
increasing temperature the diameter of crystal was decreased.
The morphology of the graphene was studied to help understand
their electrical properties. A wrinkled and sheet structure of
graphene was observed by scanning electron microscope (SEM),
which was considered to be favorable for charge transfer. Fourier
Transform Infrared spectroscopy (FTIR) analiysis confirmed that
with the reduction process the functional group can be reduced
by adding Zn. By adding more Zn powder the functional group
was disappear, and its make the elctrical conductivity of
graphene increased Four Point Probe test used to measure the
electrical conductivity. Graphene can be syntesized by
hydrothermal process. And the best variation of mass of Zn and
hydrothermal temperature is 2.4 grams and 180
o
C. the highest
electrical conductivity is 0.12526 S/m
