Abstract

Conventional parking systems often cause problems such as long queues, delays in recording, and lack of efficiency in vehicle data management. Therefore, this study designed an automatic parking system using Arduino Uno combined with HC-SR04 ultrasonic sensors, servo motors, input buttons (push buttons), and a Python Graphical User Interface (GUI). When a vehicle is detected by the sensor, a 16x2 Liquid Crystal Display (LCD) will display a welcome message and instructions to the user to press the button to print a parking ticket. This system records the vehicle's entry time and generates a ticket with a unique Identification (ID) code and arrival time. All vehicle data is stored in a Comma-Separated Values (CSV) file to facilitate monitoring and calculation of parking fees when the vehicle exits. This system can calculate the total parking cost based on the duration of parking at the predetermined rate and display parking user data on the GUI. Based on testing, the system can detect vehicles at an effective distance of 5–15 cm using ultrasonic sensors, open and close the barrier using a servo motor in approximately 1–2 seconds, and print tickets via a thermal printer in less than 3 seconds. These results indicate that the developed system can operate automatically and efficiently, so that it has the potential to be a solution to reduce problems in manual parking management.

Abstract

Clean water is essential for public health and quality of life. Yet, many rural areas in Indonesia still rely on well water that often has high turbidity, too many dissolved solids, and risks of biological contamination. To help solve these problems, this study created and tested a Smart Digital Measurement System using Internet of Things (IoT) technology to monitor and improve water quality. The system includes a digital monitoring unit with pH, TDS, and turbidity sensors, which send data to the Blynk IoT dashboard and a Telegram bot for notifications. It also uses a multi-stage filtration unit with sedimentation filters, activated carbon, and UV sterilizers. Tests on wells in Gesikan, Tuban, showed the system worked reliably, with an average data transmission delay of 1.72 seconds, sensor errors below 5%, and 99% uptime over seven days. Water quality improved: pH levels rose to nearly neutral (6.8 to 7.0), TDS dropped by more than half (from 520–560 ppm to 240–260 ppm), and turbidity fell by about 75% (from 30–35 NTU to 6–8 NTU). These results show that the system offers an affordable way to help rural communities get cleaner water and supports progress toward SDGs 3 (Good Health and Well-being) and 6 (Clean Water and Sanitation).

Abstract

The use of small-scale solar energy is one of the strategic solutions for electricity needs in remote areas and outdoor activities. As the need for portable electrification increases, the development of solar backpack systems is becoming a practical and sustainable alternative. This research aims to design and test a portable backpack system based on a thin film solar panel with a capacity of 20 Wp, equipped with a 12V solar charge controller and a 7.2 Ah battery. The system is designed with two outputs, namely 12V DC and 5V USB, to support lightweight devices such as LED lights and smartphones. The test was carried out at two different locations, namely Mount Lorokan and Mount Penanggungan, with data taken which included latitude, longitude, solar elevation angle, PV voltage, PV current, and output power. The measurement results show that there is a variation in the performance of solar panels according to geographical conditions and solar elevation angles. On Mount Lorokan, the peak power reaches 8.55 W at an angle of 75°, while on Mount Penanggungan the maximum power is slightly higher, which is 8.6 W at an angle of 78°. Mount Lorokan excels at maximum power, Penanggungan shows more stable performance at low to medium angles. This research contributes to the development of a portable electrification system based on renewable energy that supports power continuity in locations without access to electricity.

Abstract

Cardiovascular disease (CVD) motivates affordable, continuous monitoring of heart rate and peripheral oxygen saturation (SpO₂). We present a single-MCU device using an ESP32 and MAX30102 photoplethysmography sensor that acquires heart rate and SpO₂ and streams data to a ThingSpeak dashboard. Performance was evaluated over four consecutive days under normal conditions, with five paired measurements per day against a clinically approved fingertip oximeter. Using all paired observations, the proposed design achieved low errors with RMSE = 0.84 bpm for heart rate and 0.59 percentage points for SpO₂, the maximum absolute error did not exceed 1 bpm or 1 pp, respectively. These results demonstrate end-to-end operation and good agreement with reference in resting conditions.

Abstract

In today's world of education, teachers are required to be creative in the teaching process. Teachers are very influential in the development of education in Indonesia. One indicator of a country's progress can be seen from education. This research uses descriptive experimental research that uses a qualitative approach. This research is descriptive because this research does not use a particular method but only uses existing facts and is temporary. The DOL Circuit System is used in three-phase induction motor starting systems and is designed to minimize very high starting current surges. The three-phase induction motor starter system with the DOL circuit works directly to provide 380 VAC voltage to the motor coil so that the motor rotates immediately. The first condition is when the MCB is activated the L2 lamp output immediately activates as a sign that the DOL circuit is on standby. Then the second condition describes the circuit when the MCB is active and S2 is pressed, K1 will be active so that the resulting output is L3 on. Entering the third condition shows that the MCB remains active and S1 is pressed, the output that occurs is L2 lights up. The fourth condition where the MCB remains on then EMG is activated, the output that occurs is L4 lights up. In the fifth condition, the MCB remains on and the TOR is activated, so that the outputs, namely L1 and L2, light up simultaneously.

Abstract

This research aims to develop an effective solution to reduce harmonics through the design and implementation of a triple-tuning filter. High harmonic levels, which exceed the IEEE 519-2014 standard limits, can reduce system efficiency and power quality. The research method includes a literature study and simulation using MATLAB software. This simulation designs a triple-tuning filter with three LC resonance branches to suppress fifth, seventh, and eleventh order harmonics. The prototype design was tested based on electrical load condition data at the Electrical Engineering Department Building of Medan State University. The simulation results show that the triple-tuning filter significantly reduces the Total Harmonic Distortion (THD) value. The initial THD value of 31.8 percent was successfully reduced to below the standard limit of five percent. In conclusion, the triple-tuning filter has been proven to be an effective and applicable solution in harmonic mitigation in power systems, while also providing practical and academic contributions in the field of Electrical Engineering.
