Abstract

A pure sine inverter has been successfully designed by utilizing the EG8010 microcontroller which is used as an alternative energy source when the main power grid is cut. This pure sine inverter tool functions to stop the conversion when the power drops from the minimum value. This tool consists of a microcontroller to run the DC to AC converter instructions for 380 volts. Meanwhile, DC functions as a voltage source that provides the overall voltage. The signal waves that have been converted from DC to AC on the EG8010 Module are needed to control FET which functions as a signal amplifier. This signal is used to drive four FET n-channel and IRF480 which work alternately in sending data to the power FET to form an H-Bridge bridge and the output signal from the H-Bridge. Furthermore, the H-Bridge bridge and the output signal from the H-Bridge are sent through the transformer, so that the final output signal is a pure DC to AC sine wave. The resulting pure sine wave dc to ac can provide a maximum power of 240 watts.

Abstract

This study aims to study the characterization of the pump control system in a mini open channel water flow simulator. This pump control system aims to facilitate operators in controlling pumps based on the Internet of Thing (IoT). The sample in this study focuses on red objects, where the sample can be monitored through a recording device that has been provided, and can be made in the form of realtime graphics. The results showed that in the simulator trial, the pump control system and the recording device were in the good category. After repairs are made, the development results are in the very good category, because they produce accurate results on the pump control system. Thus, the pump control system can be used and developed for large-scale canal water flow.

Abstract

The test has been successfully carried out on optical fibers to be used as a macrobending tilt sensor using SMF-28 single mode optical fiber. The optical fiber was molded with silicon rubber, then connected to a laser light and a power meter to see the intensity of the laser power produced. The principle is carried out using the macro bending phenomenon on single mode optical fibers, where the laser light intensity in the fiber optic cable will decrease if there is a bend or bending in the fiber optic cable. We can observe the power loss resulting from the macro bending process to find out how sensitive the optical fiber is to changes in a given angle. The resulting optical fiber sensitivity value is -0.1534o/dBm.

Abstract

The sensor analysis or flow-meter measuring instrument has been successfully carried out on the signal output to see the stability or accuracy of a measurement. The flowmeter measurement value was analyzed using a rainfall simulator. The rainfall intensity value will then be predicted using the Kalman filter. Kalman filters can predict various data or output signals so that the measurement results can be more stable and accurate. This research methodology consists of several stages, namely the stages of literature study, designing research tools and components, designing systems, making or assembling tools, testing all components, programs and testing the flow-meter output signal record. The flowmeter is controlled by the Arduino Nano microcontroller. Tests were carried out in this study ten times, with a time span of 60 seconds for each experiment. The increase in water flow was detected by the flow-meter which was then captured by the hercules application and the data was then copied to Ms. Excel. After the rainfall intensity value is obtained, the value will be estimated using the Kalman filter. The estimation results will show the stability and accuracy value of the flow-meter.

Abstract

Styrofoam had many purposes, especially for the safety of electronic objects, because it is light, durable and strong. The volume of styrofoam is enormous, reaching 30% of total waste in the world. Therefore, it causes problems if disposed of and it will become a very inconvenient waste and it can undermine the environment. This study aims to determine the effect of adding former styrofoam waste to asphalt on the characteristics of the 60/70 pen asphalt. The sample was made by melting the Styrofoam with Xylene then putting it in heated asphalt and then stirring it evenly. Next, Styrofoam enters the material into the sample container and then is refrigerated outside for 1 hour. After that, the sample is immersed in water for 3 hours. The sample meets the asphalt requirements test for each sample including penetration test, softening point, flash point, burning point, density, and ductility. This shows that the higher the concentration, the addition of styrofoam mixed with asphalt resulted in conversion and increased performance of the mixture. While at density, it appears that the addition of Styrofoam results in a lower density value.

Abstract

The data collector to calculate the efficiency of the pure sine inverter DC to AC based on the level of efficiency, voltage and current stored automatically in Micro SD has been successfully designed. This data collector is built from the Arduino Nano (ATmega328) module as the controller and uses a Micro SD Card as a storage medium. The equipment storage results are displayed in real time using the RTC and LCD as a display medium for the measurement results of the voltage sensor and current sensor. The data logger is designed to be useful for storing data from the measurement results of the DC to AC inverter which consists of voltage, current and data collection time. The data every 16 seconds will be stored automatically on the Micro SD. The results of the reading error of the voltage sensor and current sensor are 1.088% and 1.72%, respectively. The results of the error reading the voltage sensor and current sensor are still precise, so the efficiency obtained in this study is 78.37%.

Abstract

A DC to DC converter has been built and research has been conducted to examine the effect of load on the output voltage of the DC to DC converter with fixed oscillation frequency. This converter DC to DC circuit uses a 12 V DC battery as an input voltage source connected with a step-up transformer until it is successfully raised to 380 V DC. The load given to the DC to DC circuit converter in the form of lamps, varies from 40 watts to 960 watts with a fixed oscillation frequency of 65 Khz that has been determined by the microcontroller. The test results showed that the output voltage value decreased in accordance with the increase in load so that when the load of 960 watts obtained the output voltage of 220 V DC.
