Abstract

Bat habitats often coexist with human life, especially in homes, these mammals usually perch on the roofs of rooms or warehouses. In general, bats are parasites and pests for human life, therefore researchers have designed an automatic bat pest-repellent tool based on a microcontroller. This study aimed to create an automatic bat pest-repellent tool based on a microcontroller and electronic components as support for the circuit. This research method used three parts, namely input, output, and control. Where Arduino functioned as a controller for the entire circuit, while the ultrasonic sensor functioned as input while the Df player and speaker functioned as output. In this study, the researcher conducted 10 tests to determine the performance of the designed tool. After conducting 10 tests, the speaker produced a sound to repel bats, and the ultrasonic sensor was used as a detector of bat movements, in this test the distance of the ultrasonic sensor detected bats has been programmed, it was 5 cm to 50 cm.

Abstract

  The increasing complexity of modern engineering systems and the demand for efficient, cost-effective, and high-performance designs have driven the adoption of intelligent computational strategies in mechanical engineering and physical sciences. Traditional simulation and optimization techniques often struggle with nonlinear, multi-objective problems that span both material and structural design spaces. This study aims to develop a unified smart algorithmic framework capable of optimizing both mechanical systems and material properties concurrently. The research focuses on integrating data-driven models with physics-informed techniques to improve predictive accuracy, computational efficiency, and practical applicability. The proposed framework combines artificial neural networks (ANNs), physics-informed neural networks (PINNs), genetic algorithms (GAs), and Bayesian optimization to form a hybrid multi-objective optimization system. A case study on an electric vehicle (EV) suspension system is used to validate the approach. Surrogate models were trained on finite element analysis (FEA) data and applied within a Pareto optimization loop to explore trade-offs among mass, fatigue life, and material cost. The framework achieved a 27% reduction in structural mass, a 35% increase in fatigue life, and a 13% decrease in material cost. Surrogate models attained R² values exceeding 0.90, with validation showing less than 5% deviation from FEA results. Sensitivity analysis confirmed design robustness under input variation. The findings demonstrate the effectiveness of smart algorithms in co-optimizing systems and materials. The proposed framework enhances the speed, accuracy, and physical validity of intelligent engineering design.

Abstract

This research discusses the Internet of Things (IoT)-based Public Street Lighting (PJU) system to improve energy efficiency and remote monitoring. The background problem is the need to improve operational efficiency and energy savings in the PJU system. This final project aims to design and test an IoT-based PJU system that transmits real-time data between nodes and gateways using LoRa technology and the MQTT protocol. The research process involves hardware and software design, as well as system testing under various conditions. The tests measured the data transmission time and analyzed the delay using LED indicators on the gateway and dashboard devices. The test results showed significant variations in data transmission time compared to the programmed time. The programmed transmission time was 10 seconds for node 1 and 20 seconds for node 2, but the test results showed an average time of about 15 seconds for node 1 and 21.89 to 36.02 seconds for node 2. This variation is due to factors such as network communication delay, processor load, and LoRa system efficiency.

Abstract

LTE (Long Term Evolution) is a fourth-generation wireless communication technology that is currently under development, necessitating the use of efficient antennas. This research focuses on the design and realization of a Multiple Input Multiple Output (MIMO) microstrip antenna operating at a frequency of 2.4 GHz, which is essential for LTE applications. The MIMO technique employs multiple antennas on both the transmitter and receiver sides, aiming for a correlation coefficient below 0.2 to enhance communication quality and channel capacity without requiring additional bandwidth. The antenna design was simulated using CST Studio Suite 2019 software, followed by fabrication. The simulation results indicated a return loss of -25.411 dB, a Voltage Standing Wave Ratio (VSWR) of 1.113, a gain of 6.464 dBi, an omnidirectional radiation pattern, and a bandwidth of 20 MHz. Upon fabrication, the measured return loss was -18.071 dB, with a VSWR of 1.285 and an increased bandwidth of 50 MHz. The results demonstrate that the designed antenna meets the necessary specifications for LTE applications, confirming its suitability for practical use in modern wireless communication systems.

Abstract

The rapid development of Radio Frequency (RF) usage at this time causes the abundance and waste of radio frequency (RF) electromagnetic wave energy sources in the air. This RF energy source can be used as an environmentally friendly alternative by harvesting energy using the rectenna system . The rectifier antenna (rectenna) system is designed using the serial rectenna system , this system is used to improve the performance of the rectenna in converting electromagnetic waves into a direct voltage (DC) source. To design a serial rectenna system, use 3 antennas and 3 series of rectifiers . The antenna used in the serial rectenna system is a 2.4 GHz circular microstrip patch antenna for WiFi signal reception. Meanwhile, the rectifier circuit uses a 6-stage voltage doubler using a Schottky 2860 diode and a 1nF smd capacitor. From testing and measuring the serial rectenna system , the circular patch microstrip antenna is able to capture and rectify the voltage to DC. Antenna system has return loss values of -26.29 dB, -21.75 dB, and -28.57dB, VSWR 1.11, 1.16, and 1.07, impedances 51.1, 55.56, and 50.22, bandwidth 60 MHz, 60 MHz and 50 MHz with resonant frequency 2.42 GHz, 2.36 GHz and 2.48 GHz. So that the voltage generated by a single rectenna system is 51.3 mV at a distance of 25 cm. Meanwhile, the rectenna serial system can convert direct voltage of 151.3 mV at a distance of 25 cm from the source of the Access Point transmitter.
