Abstract

Various industrial equipment uses dc motors as its drive. In order for the dc motor to operate as needed, it needs to be controlled. Some of the controls applied to dc motors include control of rotation direction, speed, braking, and starting current starting. This paper proposes controlling the speed of the dc motor using a 4-quadrant controlled rectifier or phase controller using a programmable logic controller (PLC) and human machine interface (HMI) as the control center. The system design is implemented on a 1.3 HP separate amplifier dc motor. The proposed control system design is tested and validated at varying speeds. Variations in motor speed are set on the HMI screen according to needs. The test results show that the design of the dc motor speed control system using a four quadran phase controller has worked as desired. The speed of the motor can be controlled through the HMI display

Abstract

Increasing the cultivation of hydroponic plants presents challenges, particularly in monitoring water pH and controlling temperature and humidity in hydroponic farming, which are often neglected. The lack of proper monitoring can significantly impact hydroponic plant growth. This issue arises due to the reliance on manual checks, which prevents real-time and efficient monitoring. This research employs a comparative method to analyze water pH levels using both a water pH sensor and a pH meter. For temperature and humidity monitoring in the hydroponic plant area, the study compares the readings of the DHT22 sensor with online weather data, both monitored anytime via a web server. Temperature and humidity data can be accessed at any time, but the focus of comparison is on daytime, as temperature and humidity fluctuations are more drastic, with temperatures exceeding 30°C. The purpose of this test is to determine the water pH level as well as the temperature and humidity conditions suitable for hydroponic farming. Based on observations, the developed system enables real-time monitoring via a web server, demonstrating good performance and meeting efficiency objectives in automated temperature and humidity control. The implementation of this system is expected to be expanded in the future, providing a viable solution for users and enhancing process efficiency in related fields

Abstract

Work Safety is an activity and effort to create a safe work environment, preventing all forms of accidents. To implement safe actions for workers, Personal Protective Equipment (PPE) is needed for workers to protect someone in doing their work. This Personal Protective Equipment (PPE) monitoring system begins by turning on the system by flowing the power supply to the system. Then the system is set via an access point via WiFi to be able to set the system on the microcontroller GUI. Then by selecting to activate "Motion Detect" and "Auto Upload" on the GUI, the system will automatically detect all movements within the range of the camera sensor. Furthermore, the system saves the video image of the object's movement in the memory on the system and will then be uploaded to a personal computer that has been set as an FTP server. After the personal computer saves the video image, the personal computer then sends the video image to the roboflow platform server. And when the video image is sent to the roboflow platform server, the video image is classified and labeled according to the dataset that the author created in the previous python programming. And finally, the video image that has been classified and labeled is stored again in the directory that has been specified in the programming

Abstract

Accidents at railroad crossings still frequently occur due to the negligence of road users and the lack of an optimal security system. This study aims to design a prototype of an Internet of Things (IoT)-based level crossing monitoring and control system to improve traffic safety. This system uses an ESP32 microcontroller as the control center, an HC-SR04 ultrasonic sensor to detect the arrival of the train, a servo motor as a driver for the automatic barrier gate, and Blynk IoT as a remote monitoring and control platform. The research method used is the waterfall model, which includes the stages of needs analysis, system design, implementation, testing, and maintenance. The results of the study show that the developed system can work automatically in detecting train arrivals, displaying crossing status on a 16x2 LCD, and providing warnings via LED indicators and buzzers. In addition, users can control the gate manually through a Blynk-based application. Based on the tests conducted, the system has a good level of accuracy in detecting the presence of trains and responding to commands from the application with a response time of less than 1 second. Thus, this prototype is expected to be an innovative solution to improve safety at railroad crossings and reduce the risk of accidents due to human error

Abstract

Various electrical equipment utilizes direct voltage (DC) as a power source. Examples of this equipment include various electronic devices as well as DC motors and others. The direct voltage used usually has various ratings, ranging from 1.5 volts to 12 volts, and other numbers. To ensure that the direct voltage is in accordance with the tool's needs, it is necessary to control this voltage. This control is generally carried out using a power converter. In this research, buck-boost converter output voltage control will be implemented using the Fuzzy Mamdani method with an Arduino Atmega 2560. The control system developed will be tested through experiments in the input voltage range between 12 to 24 Volts, with a maximum output of 18 Volts. The experimental results show that the Fuzzy Mamdani based buck-boost converter output voltage control system successfully regulates the output voltage according to the desired reference value

Abstract

The Dahlander motor is a three-phase induction motor capable of operating at two distinct rotational speeds by altering the stator winding configuration between star (Y) and delta (Δ). This dual-speed feature is essential for industrial machines such as cranes, lathes, and conveyors that require variable speed operation. However, conventional manual control methods are still widely used, posing risks to operational efficiency and safety. This study presents the design and implementation of an automated control system for a 1.3 kW Dahlander motor using a Siemens S7-1200 Programmable Logic Controller (PLC), a KTP 700 Comfort Human Machine Interface (HMI), and an Internet of Things (IoT) platform based on Node-RED. The system supports remote control via HMI panels, personal computers, and smartphones through a web-based interface using the Profinet protocol. The control logic is developed in the TIA Portal environment, enabling selection between low-speed and high-speed modes. Experimental results demonstrate that the system effectively controls motor speed with accurate and stable operation. The integration of HMI and IoT provides real-time remote monitoring and control capabilities, enhancing operational reliability and minimizing human error. This integrated system offers a cost-effective and adaptive solution for local industries, especially small and medium-sized enterprises, to embrace Industry 4.0 technologies

Abstract

The need for an efficient and reliable weather monitoring system in areas with limited communication infrastructure has led to the development of an Internet of Things (IoT)-based solution utilizing LoRa (Long Range) technology. This study presents the design and implementation of a local-area weather monitoring system using the STM32F103C8T6 microcontroller and the LoRa RA-02 communication module. The system monitors environmental parameters such as temperature, humidity, wind speed, and air pressure using various sensors including DHT-21, BMP280, A3114, and INA219. Sensor data is collected by the transmitter node and sent via LoRa to a receiver node equipped with an ESP32 microcontroller. The receiver processes the data and sends it to the Blynk IoT platform and Google Sheets for visualization and storage. Experimental results show reliable transmission over distances up to 530 meters in dense environments and 2 kilometers in open areas. The system demonstrated low power consumption, making it suitable for solar-powered applications. The proposed solution is practical, flexible, and cost-effective, providing valuable support for weather-dependent decision-making in remote locations..
