Abstract

Due to Indonesia's year-round abundance of sunlight, solar energy is one of the renewable energy sources with substantial development potential. Photovoltaic panel output characteristics, particularly open circuit voltage (Voc) and short circuit current (Isc), are impacted by variations in solar irradiation. The purpose of this study is to examine how solar irradiation affects a 50 WP monocrystalline solar panel's Voc and Isc values. Direct measurements were made every five minutes between 10:00 and 11:30 in the morning as part of an experimental approach. Solar irradiance, open circuit voltage, and short circuit current were among the parameters that were measured. The results showed that increasing irradiance significantly affected the Isc value, while Voc tended to remain relatively stable. The highest irradiance value was 982 W/m² with a Voc value of 20.6 V and an Isc value of 3.21 A. The findings indicate that the output current of the photovoltaic panel is more sensitive to irradiance changes than the output voltage

Abstract

Attendance-data validity was essential to support accurate distribution of the Free Nutritious Meals Program. This study designed and implemented a Raspberry Pi 4-based hybrid attendance-verification system with selectable facial and fingerprint recognition. Experimental engineering was applied through device design, dataset preparation, software integration, and subsystem and integrated-system testing. Facial recognition used YOLOv5n as a trigger, MediaPipe for face detection, MobileFaceNet for embedding extraction, and cosine similarity for identity matching. The dataset produced 1,172 valid embeddings from 30 students. Testing achieved 100% fingerprint success, 100% face-detection success, and 94.7% facial-recognition accuracy. All five storage and web-dashboard functions operated as designed. The system supported local, automatic, and integrated attendance recording; however, facial-recognition performance decreased under low illumination.

Abstract

Induction motors are widely used in industrial applications due to their favorable operating characteristics and ease of speed control. However, they exhibit a relatively low power factor caused by a high demand for inductive reactive power. This study aims to improve the power factor of a three-phase slip-ring induction motor through reactive power compensation using a capacitor bank. Tests were conducted at load conditions of 1.6 Nm and 2.1 Nm, utilizing a capacitor bank with eight activation levels and a total capacitance range of 0–30 μF. The results indicate that without compensation, the power factor was 0.29 and 0.33 for the respective load conditions. Optimal compensation was achieved using a combination of switches 2, 3, and 4 (total capacitance of 28 μF), which improved the power factor to 0.83 at a 1.6 Nm load and 0.89 at a 2.1 Nm load, while simultaneously reducing the line current to near-minimum values. Conversely, activating all switches (30 μF capacitance) resulted in over-compensation, causing the load characteristics to become capacitive; consequently, the power factor dropped to 0.50 and 0.43, accompanied by an increase in line current. The findings demonstrate that selecting the appropriate capacitor bank capacity can effectively improve the power factor and reduce line current in slip-ring induction motors.
