Abstract

This research discusses the principles of measuring the electrical impedance of a solution using parallel plate probe. The method used is by injecting an AC-current in the solution within the frequency range of 1Hz - 1MHz. The electrical impedance value plotted as a function of frequency. The results of the experiment showed that the electrical impedance of a solution could be measured correctly by using this method. The surface area of the probe, the distance between the probe, and the frequency of the injected AC-current, giving the measured impedance value changes significantly. This method also proved to be used to identify the value of the concentration of the sugar solution with relatively good accuracy. The experiment results demonstrate conformity with the existing theory

Abstract

One of the factors that influence the composition of honey is the plant that became the source of nectar. Honey derived from one plant species has a different composition with honey from other plant species. This study aims to analyze the effect of the origin of honey flower on the value of electrical impedance by using impedance spectroscopy and to analyze the relationship between ash content and electrical impedance in honey. This study used four gold needle electrodes and a set of PicoScope 5244B tools to measure the value of honey impedance. Measurements are made by injecting a current of 10 μA and using frequencies 1 Hz to 2 MHz. This study also measured ash content in honey. The sample used is kelengkeng, kaliandra, randu, coffee, and rubber honey. The results showed that the origin of honey flower affects the value of electrical impedance. The relationship between impedance and ash content is the smaller the ash content in honey the impedance value is greater.

Abstract

A practical monitoring system implementing an asynchronous interrupt driven sampling technique has been developed in this research. This system is intended to acquire power-line single-phase voltage and current signals as well as their related information such as RMS values and harmonic contents. The system uses a voltage transformer and a current transducer to acquire the signals of the voltage and current. A microcontroller is used in the system to perform acquisition processes, calculation, and wireless data transmission. The design activities include the development of hardware of the system and software in the microcontroller as well as monitoring software with Bluetooth technology that will run on portable devices. As part of the research, a new sampling technique was developed to provide constant and precise timings during the acquisition processes. In this technique, some peripherals related to the acquisition process were driven asynchronously using interrupt mechanisms. Some experimentation has been carried out, and the result showed that the system implementing this technique could successfully manage the timings for the synchronous acquisition sequences. Furthermore, the use of the Bluetooth interfaces in the system allowed practical monitoring process to be performed using portable devices.
