Abstract

Abstrak-Pada penelitian ini, dilakukan sintesis grafit tereksfoliasi dari batangan isi pensil 2B (grafit). Proses sintesis dilakukan menggunakan larutan garam anorganik Na2SO4 dengan metode elektrokimia. Sintesis grafit tereksfoliasi divariasi berdasarkan konsentrasi Na2SO4. Variasi konsentrasi Na2SO4 yang digunakan adalah 0,05 M; 0,1 M; 0,2 M; 0,3 M; dan 0,4 M. Proses elektrokimia dilakukan dengan tegangan 20 V. Grafit tereksfoliasi yang telah disintesis dikarakterisasi dengan tiga jenis pengukuran, yaitu four 3 point probe, galvanostatic charge 3 discharge, dan cyclic voltammetry untuk menentukan konduktivitas dan nilai kapasitansi spesifik dari grafit tereksfoliasi. Dari hasil karakterisasi tersebut ditunjukan adanya peningkatan konduktivitas dan kapasitansi spesifik sebesar 25,6 uS/m dan 31,8 mF/g saat menggunakan konsentrasi 0,3 M dari sebelumnya yang hanya 4,56 uS/m dan 4,48 mF/g saat menggunakan serbuk batangan isi pensil 2B (grafit). Kata kunci - Grafit Tereksfoliasi, Na2SO4, Elektrokimia

Abstract

The Wire Mesh Sensor (WMS) is a tomography-based sensor that generates an image of the free space distribution in multiphase flow. The resulting distribution image can be the capacitance distribution pattern is detected by the electrode, which is dependent on the fluid parameters. Based on the concepts, the system may be an alternative option for the early detection of waterways. The goal of this study is to evaluate the performance of the WMS system in an industrial exhaust pipe. The ability of the system to identify fluids is determined using the capacitance distribution analysis from the WMS measurement. An exhaust pipe is modeled as a cylinder phantom and simulated to visualize the capacitance distribution. The WMS technique is used on a phantom made up of a homogeneous and inhomogeneous medium with changing fluid differences. The capacitance distribution of each fluid in the phantom is different. It is caused by differences in the relative permittivity of each fluid. The performance of the WMS system is evaluated by looking at the capacitance distribution changed as the geometry of the fluid volume varied. Based on the results, the WMS system is shown to be capable of easily distinguishing variations in fluid volume percentage.
