ABSTRAK

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 08 gram 16 gram dan 24 gram. Kemudian graphene oksida yang telah direduksi dipanaskan dengan menggunakan metode hydrothermal dengan variasi temperatur 160oC 180oC 200oC 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 180oC dengan konduktivitas elektrik terbaik sebesar 0.012526 Scm.


ABSTRACT

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 180oC. the highest electrical conductivity is 0.12526 Sm.
