Currently, researchers at the Research Center for Nanoscience and Nanotechnology ITB and the Faculty of Medicine UNPAD do not yet have the tools to test electrochemical-based sensors to detect the presence of cardiac biomarkers. Therefore, a tool is needed that can support the sensors that have been developed by researchers in detecting cardiac biomarkers using electrochemical methods. The solution designed in this final project is a potentiostat. In this final project book, we will discuss more specifically about the control unit system part of the potentiostat. The control unit system part of the potentiostat system is divided into several components: Microcontroller, Analog-to-Digital Converter (ADC), Digital-to-Analog Converter (DAC), and Impedance Analyzer. The designed potentiostat system is expected to generate input signals and read measurement results for three types of measurements: Cyclic Voltametry, Differential Pulse Voltametry, and Electrochemical Impedance Spectroscopy. The results of the implementation and testing of this final project are that the final product of the potentiostat has succeeded in producing an input signal for the measurement of Cyclic Voltametry, Differential Pulse Voltametry, and Electrochemical Impedance Spectroscopy. In addition, the system can also show the characteristics of the three measurements.
