Abstract

The idea of the Internet of Things (IoT) encompasses the application of technologies such as sensors and software to an object for the purpose of communicating, controlling, connecting, and exchanging data with other devices while connected to the Internet. In this study, the IoT concept developed was used to monitor and regulate conditions within the data center. The development method used is the life cycle method of system development. The development process involved modifying the Arduino Uno with an esp8266 microcontroller and a DHT-22 sensor to detect temperature and humidity in real time. The testing of IoT development was done using the black box and white box methods. Research results show that the prototyped IoT network can operate well and successfully improve data center performance. In addition, users can also access the system through websites and mobile applications to facilitate the monitoring process.

Abstract

This study explores engineering professionalism through the implementation of a smart greenhouse powered by a solar power system and PLC-based automation in an industrial area. By applying the principles of professionalism - such as integrity, technical competence, and social responsibility - this project demonstrates how engineers can design and operate energy-independent systems while maintaining work ethics and safety. The research method used a case study with the design of a 600 Wp solar power plant system, PLC programming, daily load measurements, and performance analysis. The results show that the PLTS system generates 2 kWh of energy per day, while the greenhouse load requirement is only around 1.5 kWh per day, indicating energy surplus and high efficiency. In addition, automatic control maintains temperature and humidity stability inside the greenhouse. The conclusion confirms that professionalism significantly contributes to the technical, operational, and safety success of the system and recommends the integration of professionalism in education and sustainable engineering practices.

Abstract

Shooting sport requires high accuracy and speed, making training evaluation essential for athlete performance improvement. Conventional evaluation methods are often limited, thus the application of Artificial Intelligence (AI) and Computer Vision provides an effective alternative. This research aims to analyze and classify shooting sport poses using Deep Learning methods. A dataset consisting of several thousand pose images was collected from both field recordings and publicly available sources, followed by preprocessing for coordinate extraction. Convolutional Neural Network (CNN) was employed to extract coordinate data from shooting pose images, while Long Short-Term Memory (LSTM) was applied for pose classification. Experimental results demonstrated 94% accuracy, 95% Percentage of Correct Keypoints (PCK), and 4 mm Mean Per Joint Position Error (MPJPE), with training conducted at a learning rate of 0.0001 over 150 epochs on 5% test data, involving a total of 596,642 parameters. These results indicate that the proposed CNN–LSTM model provides a reliable approach for pose analysis and classification in shooting sport. The contribution of this study lies in presenting a novel dataset and framework for AI-based shooting sport evaluation, which can enhance training feedback and broaden AI applications in sports.

Abstract

The rapid development of microcontroller technology has driven innovations in digital display systems, including the use of I2C-based LCD modules for efficient communication. However, limited access to physical hardware remains a challenge for students and novice researchers. This study proposes an online simulation model for implementing a running text system using a 16×2 I2C LCD controlled by an Arduino Uno on the Wokwi platform. The method follows a digital system engineering approach, including system design, Arduino-based programming (C++), and virtual testing. The results show that the system successfully displays scrolling text with stable performance, achieving an average delay of 200–300 ms per character shift and consistent operation without simulation errors. Memory usage remains below 60% of available capacity, indicating efficient resource utilization. Compared to previous studies that primarily use LCDs as supporting components, this work focuses on the running text module as the main system, contributing a structured simulation model for educational and prototyping purposes. These findings demonstrate that Wokwi provides an effective, low-cost, and accessible platform for early-stage development and validation of microcontroller-based display systems.
