Abstract

A control system in the form of an Automatic Transfer Switch (ATS) is needed when a blackout occurs from the PLN that will be transferred to the generator. The research problem was how to save costs for making ATS that can run efficiently. The purpose of this study was to find out how to save costs for making ATS that can run well and efficient. The method used was Research and Development. The Research and Development stages included: collecting data, designing, and testing. To save costs for making ATS, the researchers used the Timer Delay Relay (TDR), as using TDR reduces the cost of making tools because the component prices are relatively affordable. The way the ATS system works is when the PLN electricity is on, the battery will be charged by the battery charger, and when the PLN electricity goes out, the inverter will get a voltage supply from the battery, that was originally 12V will be changed to 220V. The TDR makes it easier to determine the appropriate time when the voltage is stable. Based on the experiment, the time when the voltage is stable is 6 seconds.

Abstract

The fan is a tool that is needed to rotate air circulation. In the market, fans are usually controlled manually by turning the control switch. The research problem is how to make a fan tool that can automatically turn on when there is a change in temperature. The purpose of this research is to facilitate users in using the fan. The method used is Research and Development. The stages of Research and Development include: data collection, design, and testing. The automatic fan control circuit consists of an atmega8 microcontroller integrated with a temperature sensor, button and relay. The circuit can display the temperature and can control the fan. The automatic fan control circuit is made on a PCB whose PCB layout is made using a computer with the PCB manufacturing process still using screen printing techniques. The conclusion is that the manufacture of automatic fan control devices integrated with temperature sensors, buttons and relays can facilitate the control of fans so that users do not need to control when the temperature changes.

Abstract

One of the efforts to prevent fires is by providing occupational health and safety (K3) learning. In the learning process, the material is only in videos and power points about fire prevention and control. Conversely, students more easily understand contextualized material. One of them is an automatic fire extinguisher simulation. This simulation uses a fire sensor as its input, Arduino uno as its control, and a relay as an output from Arduino. This learning media was tested on 40 people with backgrounds as students and employees. Based on the results of this learning media trial, the average questionnaire assessment reached 87.6%, so this learning medium is effective as a learning medium for fire extinguisher simulation.

Abstract

Microcontroller technology is increasingly developing, so studying it requires a real device. The learning process for microcontroller practice at the Piksi Ganesha Indonesia Polytechnic Campus does not yet have sufficient tools, especially for Arduino Uno practice. The research aims to create a tool or trainer about Arduino Uno so that it can be used to support microcontroller learning in the Electronics Engineering Study Program. The research method uses Research & Development with stages including potential and problems, information gathering, product design, design validation, design improvement, product testing, and product revision. The research results are an Arduino Uno trainer with three inputs and three outputs. It is hoped that users can more easily understand the basics of microcontrollers with the media created.

Abstract

Currently, soil moisture monitoring is only done manually, which is less accurate, even though sometimes we need a soil moisture monitoring tool to determine the soil water content in plants. This research uses a Soil Moisture sensor to measure soil moisture and the NodeMCU ESP8266 microcontroller as the main controller. The system is designed to provide accurate and efficient soil moisture monitoring through the Internet of Things (IoT). The integration of Blynk as a monitoring application offers easy access to real-time soil moisture data via mobile devices. This system is designed to help users monitor soil moisture in real-time using NodeMCU as the main platform and Blynk for user interaction. Through this system, it is expected that users can avoid the risk of water shortages by knowing the soil water content in real-time. Based on testing, this soil moisture monitoring product has a success rate of 88.2% for soil moisture accuracy and an average user satisfaction rate of 60%.

Abstract

Body temperature is an important indicator for monitoring a person's health condition. The average normal human body temperature ranges from 36–37°C. Changes in body temperature, whether hyperthermia or hypothermia, may indicate infections or metabolic disorders, making accurate and practical measurement methods essential. Conventional contact thermometers have limitations, such as long measurement times and user discomfort. To overcome these issues, a non-contact body temperature measurement system was designed using an infrared sensor. This sensor works by detecting thermal radiation emitted from the body’s surface without requiring direct skin contact. The device utilizes the MLX90614 infrared sensor, an ultrasonic sensor for distance detection, and a switch as an on/off control. Measurement results are displayed on an OLED screen and can be monitored via a smartphone through the Blynk platform. Based on testing, the non-contact body temperature measurement device achieved an accuracy level of 99.3%.
