Abstract

Priyo Sasmoko, Subali, Teguh Yuwono, in this paper explain that harmonic (current or voltage) is one of the problems that has to be solved in electric power system, especially that caused by non-linear loads. Harmonic could cause bad impacts for the electric components that sensed it. It is almost certain that using of fluorescent lamp with electronic ballast or it is called energy saving lamp can cause harmonic in electric power system. Considering of the using of energy saving lamp is increased fairly fast as residence and office lighting, so it is important to analyze and solve the harmonic that caused by energy saving lamp. From the harmonic analysis, we can know the harmonic distortion caused by energy saving lamp. And there are some efforts to reduce such harmonic distortion by using a Low Pass Filter. Keyword: power quality, harmonic, low pass filter.

Abstract

Dewantara, Priyo Sasmoko, in this paper explain that a measuring instrument is a tool used by humans to help determine parameters such as height and weight. Most height and weight gauges used today still use simple and still conventional equipment. In addition, if manually, there are still frequent measurement errors that come from the measuring instrument itself or from the human. This happens because of inaccuracies in reading measuring instruments that lack precision or perhaps from the human factor itself. The purpose of this study was to create a digital height and weight automation system accompanied by displaying its ideal weight based on height. This system is built using Arduino as a system controller. The ultrasonic sensor is used as a measure of height. Load cell is used as a measure of weight. And a 20x4 LCD to display the output. From testing and analyzing the results of measurements of height according to the actual height, the results of measurements of weight have an error percentage of 0.53% - 2.77%. The system determines the ideal or not body weight based on BMI. Keywords: 20x4 LCD, Load Cell Sensor, Arduino.ReferencesFogaswara, Eka. 2013.

Abstract

Aloisius Wisnu Lalita Dewa, Priyo Sasmoko  in this paper explain that, physical water quality can be identified in various ways, one of which is measuring the amount of solute called Total Dissolved Solid (TDS). This study aims to design and make a TDS solution by using two electrodes as sensors. These two electrodes flow alternating current and negative values alternately into water. Analog signal in the form of voltage is read by the microcontroller by converting it into a digital signal, then the microcontroller processes the data and displays the TDS value. Tests are carried out by measuring the same solution using TDS meters and salt water TDS. Testing starts from a solution of 175 ppm to 8500 ppm. Making solutions based on TDS meter factory production. The results of salt water TDS measurements showed that the measured tds values increased from 173 ppm to 8007 ppm. Error reading at 8500 ppm, this is because the reading distance of salt water TDS is only up to 8260 ppm. Keywords : TDS, conductivity, electroda, measurement device.ReferencesMalvino. 1995.
