Abstract

This study develops a modular CNN encoder–decoder framework for single-image dehazing by replacing the conventional bottleneck with interchangeable token-mixing modules such as FNet, Spatial-FNet, MLP-Mixer, and gMLP-style designs. The pipeline integrates adaptive preprocessing (CLAHE and histogram matching), photometric augmentations, and training on a controlled subset of the SOTS dataset. Comprehensive quantitative and qualitative evaluations demonstrate substantial improvements over a baseline CNN, with mean PSNR increasing from approximately 18.4 dB to the 23.0–24.0 dB range and SSIM rising from about 0.75 to roughly 0.89–0.91. However, several variants require careful hyperparameter selection and loss-weight tuning to achieve stable performance. The results offer practical guidance for deployment in real-world vision systems.

Abstract

Indonesia is an archipelagic country with most of its territory consisting of water, increasing the risk of water-related natural disasters. Seawater waves, influenced by tidal movements, are one such phenomenon, and wind speed significantly affects their height. Faster sea winds can generate higher seawater waves. To obtain related data, a system capable of detecting seawater wave height and wind speed is required. This study aims to test a LoRa (Long Range)-based seawater wave detection system that is both efficient and reliable. The system uses a BNO055 sensor to measure wave height and an anemometer to detect wind speed. The relationship between wind speed and seawater wave height is analyzed using the fuzzy Mamdani method. Results show the BNO055 sensor has 92% accuracy, the anemometer 98.4%, and the fuzzy Mamdani method yields an error rate of only 0.25%. This system is expected to enhance marine monitoring and safety efforts.

Abstract

Improving solar panel performance is challenging due to increasing of solar radiation. This study investigates the effect of variations in the angle of the flat mirror reflector on the surface temperature and electrical performance of a 10 Wp monocrystalline solar panel using an ESP32-based data acquisition system with INA219 and DS18B20 sensors. Reflector angles of 45°, 60°, and 75° were tested from 08:00 to 16:00 WIB. The results indicate that the 45° reflector produced the lowest temperature (≈60 °C), the highest average voltage (19.7–20.0 V), maximum current of 120 mA, and peak power of 2.6 W. In contrast, the 75° angle increased the temperature to 72 °C and reduced the electrical output. The study concludes that a 45° reflector angle is optimal for low-power solar panels in hot tropical environments.

Abstract

Increasing electricity demand in Tulungagung has caused transformers at Substation 1 and 2 to reach critical loading. To address this, PT PLN (Persero) UP3 Kediri added a 60 MVA transformer at the New Tulungagung Substation with load redistribution. This study analyzes the impact of the new transformer on transformer loading, power losses, and voltage profile, and identifies the most efficient network maneuver scheme during maintenance. Simulationsusing DIgSILENT PowerFactory were based on Tulungagung distribution data. results show reduced loading to 62.8% and 70.5%, improved minimum voltage from 0.91 p.u. to 0.93 p.u., and loss reduction from 2.84 MW to 2.71 MW (4.6%). Among three maneuver schemes, the third achieved the best performance with 0.94 p.u. minimum voltage and 3.90 MW losses. The new transformer significantly enhances system efficiency and reliability.

Abstract

This study compares the dimming performance of DALI and 0–10 V using three commercial LED drivers at eight dimming levels. The testing included power consumption, illuminance, and flicker stability. The results showed that DALI was able to maintain a linear dimming curve down to low levels such as 10%, 5%, and 1%, with consistent flicker within the No Risk zone. Power consumption at 0% was also low, making it suitable for applications requiring deep dimming and stable visual comfort. Conversely, the 0–10 V system performed quite well at high levels and was slightly more efficient at low power, but its performance dropped drastically below 30%. At 10%, the illuminance was almost zero and the flicker level entered the High Risk zone. Overall, DALI is more ideal for smart lighting with smooth transitions, while 0–10 V is more suitable for basic installations.

Abstract

LPG gas leaks and unmonitored kitchen environmental conditions can trigger fires and endanger health. This study developed an Internet of Things (IoT)-based kitchen monitoring system to detect Liquefied Petroleum Gas (LPG) leaks and environmental conditions in real-time. The system uses an MQ-2 sensor as an LPG gas detector, a DHT11 sensor for temperature and humidity, an MQ-135 for air quality, and an LDR for light intensity integrated with an ESP32 microcontroller and the Firebase Realtime Database. Sensor data is sent in real-time via a Wi-Fi network and displayed on an Android application with warning notifications. Performance evaluation was carried out by measuring the delay in data transmission from the sensor to the application in household kitchen conditions. Test results showed an average delay in the range of 0.24–0.36 seconds, which still meets the needs of an early warning system. This system is considered effective in improving the safety of LPG-based kitchens through real-time monitoring and fast notifications.

Abstract

Manual treadmills are low-cost and widely accessible but lack electronic systems for measuring running speed, limiting their use in interactive or gamified applications. This study presents a simple embedded system that enables real-time speed tracking on a manual treadmill using a magnetic reed switch and an ESP32 microcontroller. Each roller rotation generates one pulse which is processed through an interrupt-based algorithm to compute linear speed. The data are transmitted to a custom Unity game application to control a running avatar in real time. Experimental results show an average speed error of 2.11% with an RMSE of 0.049 m/s and an end-to-end latency of 48 ± 4.9 ms. The findings indicate that the system is accurate, responsive, and suitable for low-cost exergaming and motion-based training.

Abstract

One way to diagnosing a disease is by examining an image. To display an image on a specific component, an inverse matrix-based algorithmic decomposition technique is used. If the Lambert-Beer Law equation is subjected to a natural logarithmic operation, a linear relationship between intensity level and thickness will be produced. Furthermore, an image can be displayed based on the thickness function. By varying three different wavelengths and three different materials, three types of linear equations are obtained. This variation in wavelength affects the level of decomposition. The results show that the combination of 780 nm-808 nm-980 nm wavelengths is better in quality than other wavelength variations. In this study, a phantom composed of silicone rubber, margarine, and gelatin was used. This phantom material is representative of the human body material.

Variasi nilai resistor gain dan kapasitor pada low pass filter rangkaian analog dianalisis untuk mendapatkan kinerja hasil terbaik. Hasil pengujian menunjukkan bahwa kombinasi filter analog dan digital berhasil meningkatkan Signal-to-Noise Ratio (SNR) dari 4.61 dB menjadi 19.57 dB. Denyut jantung dari sinyal yang telah dioptimasi mencapai 61.60 BPM yang di validasi dengan peak detection yang mampu mendeteksi peak dengan benar. selain itu, Baseline Wander Index (BWI) sebesar 0.18. Hasil penelitian membuktikan bahwa sistem optimasi menghasilkan sinyal PPG yang bersih dan akurat untuk aplikasi monitoring kesehatan
