Abstract

The Fetal Doppler Simulator for calibration is a device designed to ensure the accuracy and reliability of Fetal Doppler equipment in monitoring fetal heart rate. Traditionally, calibration of Fetal Doppler devices has relied on limited methods with relatively high costs. Therefore, an alternative calibration medium that is more economical, practical, and reliable is needed. This simulator functions by generating fetal heartbeat signals with various rhythm patterns, ranging from normal conditions to pathological variations such as tachycardia and bradycardia. The research method applied was Research and Development (R&D), which included needs analysis, design planning, feature integration, prototype construction, and performance testing. The test results showed that the Fetal Doppler Simulator was able to generate stable heartbeat simulations with measurement values that remained within acceptable tolerance limits (≤5%). Based on these findings, it can be concluded that the development of this Fetal Doppler Simulator is feasible and effective as a calibration medium. This research is expected to offer a practical alternative for healthcare facilities to perform Fetal Doppler calibration at a lower cost.

Abstract

The diagnostic accuracy and success of ultrasound-based intervention procedures depend heavily on the quality of device calibration and the expertise of medical personnel. The development of ultrasound phantoms that can realistically replicate the acoustic and mechanical properties of human soft tissue is a crucial requirement in medical education and the standardisation of electromedical technology. This study aims to develop and evaluate a method for producing soft tissue USG phantoms with modified viscosity and elasticity using polyvinyl alcohol (PVA) material, as well as integrating 3D printing technology to achieve anatomical accuracy. The phantoms were developed using a mixture of low and high viscosity PVA variants with the addition of ethylene glycol as a freeze-protectant. The fabrication process was carried out through a strictly controlled freeze-thaw cycle to manipulate the shear modulus and viscosity separately. Characterisation was performed through longitudinal sound velocity measurements (frequency 5–20 MHz), microstructure evaluation with a scanning electron microscope (SEM), and viscoelastic property testing using shear wave viscoelastography based on the Kelvin-Voigt model. The results show that the use of cryoprotectant produces a more homogeneous microstructure with a shear modulus of approximately 2.17 kPa and a viscosity of approximately 2.0 Pa · s, which is close to the physiological characteristics of human soft tissue. Acoustic parameters showed a sound velocity ranging from 1510–1571 m/s with an attenuation exponent of 1.23–1.38 dB/cm/MHz, meeting clinical range standards. The integration of natural fibres into the bio-elastomer matrix successfully created anisotropic properties resembling fibrous tissues such as muscle. The independent viscosity modification approach and the use of additive manufacturing provide a flexible platform for producing high- precision ultrasonic phantoms. This innovation supports the development of standardised and safe clinical intervention training tools, as well as reliable calibration instruments for the development of future imaging techniques such as elastography. Keywords: Ultrasonic Phantom, viscosity, PVA, 3D Printing, Medical Calibration.

Abstract

The increasing number of vehicles in urban and suburban areas has led to traffic congestion, resulting in longer travel times, higher exhaust emissions, and an increased risk of accidents. Conventional fixed-time traffic signal systems often fail to respond dynamically to changing traffic conditions, leading to inefficient vehicle queues. This study proposes the development of an adaptive traffic signal system that utilizes YOLOv11 and fuzzy logic to detect vehicle volume and adjust green light durations in real time. YOLOv11 is employed to detect vehicles in each lane, while fuzzy logic is used to regulate green signal durations based on the detected vehicle counts. Experimental results demonstrate a detection accuracy of 0.92 and a recall of 0.93. The green light duration varies from 80 seconds for low traffic volumes to 100 seconds for high traffic volumes. The traffic signal cycle is dynamically adjusted according to vehicle density, with a maximum total cycle time of 100 seconds. Overall, the proposed system is proven effective in reducing congestion and improving traffic management efficiency at intersections with high vehicle volumes.

Abstract

The Anemia is a global health issue affecting many individuals worldwide. Traditional anemia detection through invasive blood testing is often costly, time-consuming, and requires trained medical personnel. This study developed a non-invasive anemia detection system based on Photoplethysmography (PPG) technology and fuzzy logic to estimate hemoglobin (Hb) levels and classify the degree of anemia. The system uses a PPG sensor to measure red and infrared light intensities, which are used to calculate the ratio and estimate the hemoglobin levels. The fuzzy logic system then classifies the estimated Hb results into the categories of Severe Anemia, Moderate Anemia, and Mild Anemia. The results of the study indicate that this system provides an estimated hemoglobin level with an accuracy of 88.42%, and can classify anemia degrees with results comparable to conventional blood testing. This system offers a more practical, efficient, and non-invasive alternative for anemia detection and has the potential to be used for self-health monitoring.

Abstract

This community service activity aims to develop a maintenance model for a 3 kWp solar power plant (PLTS) system that is suitable for implementation in small-to-medium public service areas in Sayung, specifically the pilgrimage area of the Tomb of Sheikh Abdullah Mudzaki. The coastal setting of tidal flooding, abrasion, high humidity, and limited field access requires a more disciplined operation and maintenance (O&M) approach than typical inland locations. The methods used include synthesis of evidence from initial scans of Consensus and Scite, verification of official regional and national sources, and in-depth analysis of international standards and literature on PLTS O&M, performance monitoring, humidity/corrosion, and community-based electrification management. The synthesis results indicate that a 3 kW hybrid configuration with a 48 V battery is the most balanced option for locations requiring a steady supply when the grid is disrupted, while an on-grid system is cheaper but dependent on the grid, and an off-grid system is more independent but requires more stringent battery and charge controller design. The recommended maintenance program combines simple daily-weekly inspections by local operators, monthly-quarterly inspections by trained technicians, recording of logbook-based performance indicators, and community training emphasizing occupational safety, module cleaning, connection checks, and disturbance response. This article presents a draft maintenance schedule, training curriculum, cost estimates, monitoring-evaluation indicators, and coastal risk mitigation strategies that are ready to be adapted into a community service journal manuscript.

Abstract

A suction pump requires periodic vacuum-pressure verification to support consistent performance assessment and reliable documentation. This study developed an Internet of Things (IoT)-based Digital Pressure Meter (DPM) that displays pressure in mmHg, Pascal (Pa), and bar and transmits measurement records to Google Sheets. The device integrated an Arduino Mega 2560, an MPX5050DP pressure sensor, a DHT22 sensor, a TFT LCD, and an ESP8266 module. Testing was performed at 0, 50, 100, 150, and 200 mmHg with five repetitions at each point and comparison against a Fluke DPM4. The analysis included mean, standard deviation, coefficient of variation, bias, mean absolute percentage error (MAPE), and linear regression. Across the four non-zero points, the relative error against the set pressure ranged from 1.75% to 4.02%, with a MAPE of 2.68%; the coefficient of variation ranged from 0.40% to 2.95%. The relationship between set pressure and device output was y = 0.9735x + 1.0804 with R² = 0.9996. Relative differences from the reference-device means ranged from 1.12% to 5.02%, averaging 2.61%. The IoT system successfully stored pressure, timestamp, serial number, temperature, and humidity; however, decimal formatting for bar values was inconsistent in Google Sheets. The prototype demonstrated strong linearity and repeatability as a pressure-testing and documentation aid. Further work should establish measurement uncertainty, hysteresis, long-term stability, and metrological traceability before the device is used as a calibration standard.
