Abstract

The rapid development of Internet of Things (IoT) and embedded systems has significantly transformed conventional manual systems into automated and integrated solutions. One of the critical applications is in attendance systems and environmental monitoring, which are still commonly implemented manually and prone to errors, data manipulation, and inefficiency. This study aims to design and implement a smart attendance system integrated with classroom environmental monitoring using the ESP32 microcontroller. The system utilizes an RFID RC522 module for user identification, a DHT11 sensor for temperature and humidity monitoring, a PIR sensor for motion detection, and an LDR sensor for light intensity measurement. The collected data are processed by the ESP32 and displayed in real-time through a 16×2 LCD interface, while actuators such as a DC fan, buzzer, and LED indicators respond automatically based on system conditions. The research methodology includes hardware and software design, system integration, and performance testing. A threshold-based control algorithm with hysteresis is implemented to ensure stable fan operation and avoid frequent switching. Experimental results indicate that the system successfully performs accurate RFID-based attendance recording, real-time environmental monitoring, and automatic fan control when the temperature exceeds the defined threshold. The integration of multiple sensors enhances system functionality and improves energy efficiency. Therefore, the proposed system can be considered a reliable prototype for smart classroom applications that combines attendance automation and environmental control in a single platform.

Abstract

The rapid development of embedded systems technology has driven the advancement of more effective and autonomous home security systems, particularly in environments with limited internet access. Potential risks such as fire, gas leakage, and physical intrusion require an early detection system that can operate in real time and reliably. This study aims to design and implement a prototype of a home security system based on ESP32 using a multi-sensor approach and SMS-based notification. An experimental method was employed, including system design, hardware and software implementation, and performance testing. The proposed system integrates a PIR sensor for motion detection, an MQ-2 sensor for gas and smoke detection, a flame sensor for fire detection, and an SW-420 vibration sensor for physical disturbances, supported by a SIM800L GSM module for communication. The results show that the system is capable of detecting hazardous conditions in real time with good responsiveness, where the flame sensor has the fastest response time of approximately ±1 second, PIR and vibration sensors respond within ±1–2 seconds, and the MQ-2 sensor requires ±2–5 seconds depending on gas concentration. The system also successfully sends SMS notifications with an average delay of 5–10 seconds depending on network signal quality. Overall, the system demonstrates stable and effective performance, making it a reliable and cost-efficient embedded-based home security solution that does not depend on internet connectivity and is suitable for various environmental conditions.

Abstract

The rooftop of the University of Medan Construction building which has an area of 210 m2 can be used as a solar power plant (PLTS). Installing PLTS in buildings has several advantages, namely as a long-term energy investment and easy to integrate with the grid electrical system. PLTS is designed to save electricity consumption. In addition, if PLTS is connected to a battery, it can meet some of the energy needs at night. To design a PLTS installation in the Integrated Laboratory building, this research uses technical and economic analysis methods. Technical analysis is carried out to determine the capacity and number of PV mini-grid components required for installation. While the economic analysis aims to calculate the investment costs and the length of time for the return on investment compared to buildings without PV mini-grid installations. Based on this research, the results show that the amount of energy required for the Integrated Laboratory building is 482.148 kWh, while the planned PLTS is able to provide energy of 216,128 kWh. The PLTS design requires an initial investment of Rp. 927,700,894,-. So by using the Payback Period (PP) method, it can be concluded that the planned design is feasible, because the comparison of the cost of return on investment is 9.13 years faster than the project age that has been determined previously, which is 20 years.

Abstract

The development of robotics and embedded systems has increased the need for accessible learning media to support the understanding of basic control concepts. However, industrial robotic systems are generally expensive and complex, making them less suitable for introductory learning. This study aims to design and evaluate a 4-degree-of-freedom (4-DOF) robotic arm based on ESP32 as a learning medium for basic control systems. The research method includes hardware and software system design, implementation of a Bluetooth-based control system using an Android gamepad interface, and experimental testing. The system applies an incremental control method combined with a Degree of Freedom mechanism to regulate actuator movement gradually. The evaluation covers control mapping accuracy, system responsiveness, angle constraints, startup stability, serial monitoring, and response consistency. The results show that the system successfully executes all control commands with accurate input-output mapping and stable performance. The system maintains actuator movement within safe angle limits and operates without disturbance during startup. In addition, the serial monitoring feature enables real-time visualization of the control process. The findings indicate that the developed system is suitable as a low-cost educational platform for learning basic robotic control concepts due to its simplicity, intuitiveness, and ease of implementation.

The system integrates a PIR sensor for motion detection, a magnetic door switch for door status, an MQ-2 sensor for gas detection, and a flame sensor for fire detection. A buzzer is used as an alarm, while a 16x2 LCD provides real-time system information. The method includes system design, hardware assembly, programming, and functional testing. The results show that the system can detect various hazards and provide immediate alerts through sound and display. This indicates that a low-cost, integrated security system can be effectively implemented for residential safety.

Abstract

An evaluation of the drinking water supply system is necessary to ensure the fulfillment of community water needs and the operational sustainability of clean water services. This study examines the performance of the clean water distribution system of the Lalan Branch through an analysis of intake capacity, customer water demand, and distribution efficiency using operational data from August 2025. The actual intake capacity was recorded at 12,816 m³/month, with a maximum potential of 19,224 m³/month. Water distribution amounted to 9,468 m³/month, while measured customer consumption was 9,105 m³/month. Based on SNI standards, customer demand is 6,264.48 m³/month. The difference between production and distribution results in an NRW value of 26.1% (3,348 m³/month), influenced by the backwash process and technical network losses. The findings indicate that intake capacity is sufficient to meet customer demand, but distribution efficiency still needs to be improved.

Abstract

Polusi udara merupakan ancaman serius bagi kesehatan masyarakat, khususnya di kawasan perkotaan dan industri di Indonesia. Penelitian ini bertujuan merancang dan membangun sistem pemantauan kualitas udara secara real time berbasis mikrokontroler ESP32 yang terintegrasi dengan platform Blynk IoT. Sistem menggunakan sensor MQ-135 untuk mendeteksi konsentrasi gas polutan, serta sensor DHT11 dan DHT22 untuk mengukur suhu dan kelembaban udara. Untuk meningkatkan akurasi data suhu dan kelembaban, diterapkan algoritma sensor fusion berbasis pembobotan, di mana DHT22 diberi bobot 70% dan DHT11 sebesar 30%. Data hasil pengukuran ditampilkan secara lokal melalui LCD I2C 16x2 dan dikirimkan ke dashboard Blynk IoT melalui koneksi Wi-Fi untuk pemantauan jarak jauh. Sistem juga dilengkapi indikator LED tricolor dan buzzer aktif sebagai peringatan visual dan audio berdasarkan tiga kategori kualitas udara: BAIK (ADC < 1000), SEDANG (ADC 1000–2499), dan BURUK (ADC ≥ 2500). Pengujian dilakukan di empat lokasi berbeda, yaitu ruang terbuka, ruang kelas ber-AC, kamar mandi tertutup, dan dapur saat aktif memasak, dengan hasil nilai ADC masing-masing 487 (BAIK), 612 (BAIK), 1.876 (SEDANG), dan 2.784 (BURUK). Hasil pengujian menunjukkan bahwa sistem berhasil mendeteksi dan mengklasifikasikan kualitas udara secara akurat, dengan data terkirim ke Blynk Cloud setiap 5 detik dan packet loss hanya 1,2%. Sistem ini terbukti menjadi solusi pemantauan kualitas udara yang akurat, terjangkau, dan andal berbasis IoT.

Abstract

This study is motivated by the limitations of systems that can represent the working principles of elevators in a practical and applicative manner within the field of control systems. The purpose of this research is to design and develop a mini elevator prototype based on two Arduino Uno microcontrollers communicating via the Inter-Integrated Circuit (I2C) protocol. The method used is experimental research with a system engineering approach, including system design, assembly, programming, and testing stages. The proposed system consists of a master Arduino as the main controller and a slave Arduino for controlling the automatic door system and sensors. The main components include a DC motor as the driving system, limit switches as position sensors, an ultrasonic sensor for safety detection, and a servo motor for the automatic door mechanism. The test results show that the system is capable of responding quickly to button inputs, accurately stopping the motor based on limit switch signals, and operating the automatic door system effectively. Furthermore, I2C communication between the two microcontrollers runs stably and in real-time. Therefore, the proposed prototype successfully implements a closed-loop control system and can serve as a reference for the development of microcontroller-based control systems.
