Abstract

Holter ECG monitor is a device that records the patient's heart activity throughout the day, but the patient's body movements can cause artifacts that interfere with ECG signal quality. This study aims to improve the performance of Holter Monitor by comparing Infinite Impulse Response (IIR) and Finite Impulse Response (FIR) filters in reducing motion artifacts. Filters were applied at various orders using Butterworth and Window methods. Analysis was performed with Fast Fourier Transform (FFT) to evaluate the effectiveness of the filters in reducing artifacts. The results show that digital filters significantly reduce motion artifacts. FIR filters at high orders (6 and 8) provide a more stable signal with an average SNR value of 10.3282 at order 8. While the IIR filters at low orders (2 and 4) with an average SNR of 12.0281 at order 2, reduced the artifacts well, but at high orders were unstable and resulted in signal distortion. This research is expected to assist medical personnel in analyzing better heart signal data and improve the quality of portable heart monitoring for patients undergoing daily activities, while enabling more efficient data transmission without removing the SD Card.

Abstract

Baby incubator transport is an essential device in supporting the stability of a baby's body temperature during medical transportation. However, one of the main challenges is the efficient use of battery power, which affects the duration of operation without recharging, especially in emergency situations. An inefficient temperature control system can accelerate power drain, thus threatening the safety of the infant during the transportation process. This research aims to analyze the use of temperature control in Baby Incubator Transport with PID-Fuzzy method to assess the efficiency of battery power usage. The main contributions of this research are Improving battery power efficiency and extending battery life thereby reducing the need for battery replacement and saving operational costs, integrating PID-Fuzzy control concepts in medical devices such as baby incubator transport. This research uses a combined PID-Fuzzy method on a baby incubator transport device. This method is done to maintain temperature stability as well as battery power consumption. The research findings show that the use of the PID-Fuzzy control method can reduce power consumption by up to 70%. In addition, temperature stability is better maintained with smaller deviations, making it safer to use during baby transportation. The system is able to respond to temperature changes more quickly and reduce overload on the power system. For further research, it is recommended to replace the battery with a Lipo Lithium-polymer battery, Heater is adjusted to the power consumption and wattage is lowered, Blower Chamber size is replaced with a larger one. In addition, further testing is needed to test the durability of the system in environments with more extreme conditions and longer transportation simulations.

Abstract

Ultrasonography (USG) is an examination technique as one of the diagnostic aids in primary health facilities, including community health centers. With the availability of USG services, it certainly makes it easier for the public to get faster health screening and monitoring. To minimize the disparity between the number of doctors and the number of health facilities, a telemedicine system can be utilized to make services more efficient. This study was designed to create a system that can utilize Raspberry Pi as a storage medium for USG images. To ensure that no image data is lost during storage, Raspberry can be opened on another computer so that it can ensure that the USB function can work normally. The results obtained an error of 0% image loss from the sent USG images, so that it is certain that no images are lost during transmission. It is hoped that the creation of this module can be useful as a basis for developing research on sending images on further USG.

Abstract

Syringe pump is a life support device that functions to provide drugs in the form of fluids through the vein to the patient's body in a measurable and consistent within a period of time. This research is designed to make the syringe pump more stable, equipped with PCA (Patient Controlled Analgesia) mode, and IoT-based flowrate monitoring. The contribution made by the author is to improve the working system of the syringe pump to be more stable which is equipped with a PCA mode that functions to inject liquid according to the patient's needs, and facilitate remote flowrate monitoring using IoT. In this research, the author uses the PID method to improve the stability of the motor according to the flowrate setting. From the test results that have been done, the flowrate stability of the PID system is quite good in all settings. The resulting rise time is good enough to reach the setpoint, the average occurs in seconds 1-5, the fastest rise time occurs at a flowrate setting of 5 ml / h, which is 1 second and the longest rise time occurs at a flowrate setting of 20 ml / h, which is 5 seconds. The highest overshoot occurs at a flowrate setting of 50 ml/hour with a value of 1.98 ml/hour and the lowest occurs at a flowrate of 5 ml/hour with 0.44 ml/hour. The highest and lowest stability occurs at a flowrate setting of 10 ml/hour, which is 1.5% and 6.5%. In PCA mode, the largest error obtained is around 1% in all settings. IoT-based flowrate monitoring is good, the value displayed on the LCD in real time is sent and displayed on the web. Based on the results of the data that has been obtained, the PID system is still not optimal in controlling the stability of the flowrate so that in the future it is necessary to find a suitable and balanced combination of Kp, Ki, and Kd values.

Abstract

The diagnosis of Arrythmia is primarily made through an Electrocardiogram examination. This test is performed as part of a medical screening, or used to assess the administration of medications or medical procedures on the heart. Another common method for diagnosis of heart abnormalities is through heart sound analysis. Phonocardiography can be used to record sounds produced by the opening and closing of heart valves. This study uses threshold-based and time-based rule-based methods for the detection of S1 and S2 peaks in Phonocardiography signals, estimation of Hear Rate and early detection of Arrhythmia, and improves the implementation of real-time Arrhythmia detection. The HR module has been shown to have high accuracy in detecting heart rate in tachycardia, normal, and bradycardia conditions, with minimal error (0% to 4.1%). The measurement results on mannequins and patients showed a small difference between the HR module and the reference standard. PCG is effective for early detection of arrhythmias as a non-invasive alternative to ECG. Using a rule-based approach and time rule-based system, this system can measure the interval between S1 and S2, and S2 to the next S1 which is then used to calculate the heart rate and can detect arrhythmias in real time. The implication of this study is that the use of PCG integrated with rule-based threshold system can reduce the need for time-consuming and expensive manual ECG analysis. This automated system allows for faster and more accurate diagnosis, providing benefits for real-time arrhythmia monitoring.

Abstract

ABSTRACT Hearing loss is a condition in which there is a disorder in the normal hearing process in one or both ears. Hearing loss conditions based on the hearing threshold are mild, moderate, severe, and very severe hearing loss. To find out hearing loss, an audiometry examination can be performed. Audiometry is a tool that functions to determine the function of hearing and the degree of deafness experienced by the patient. The purpose of this study is to apply hearing threshold for the identification of hearing loss using pure-tone audiometry. The results when tested on the module compared with conventional audiometry equipment showed that there was an average value difference between manual mode and audiometry in the left ear, which was between 1.00dB to 5.00dB (1.00% to 20.0%) and in the right ear between 1.25dB to 3.75dB (4.2% to 30.0%). Although there is a difference in the calculation of the average value of the hearing threshold, the average value of the hearing threshold still shows in the same range of hearing threshold degrees of deafness between manual mode, automatic mode and in the audiometry device used as a comparison.

Abstract

Post-stroke rehabilitation often focuses on restoring upper limb mobility, which is critical for regaining independence in daily activities. Upper limb exoskeletons are increasingly used as assistive devices for rehabilitation, enabling controlled, repetitive movements to aid recovery. However, accurate control of these devices remains challenging. This study explores the application of machine learning (ML) to improve the accuracy of upper limb exoskeleton movements by utilizing electromyography (EMG) signals. The system integrates Raspberry Pi Zero 2W, Muscle Sensor V3, and MPU6050 to capture and process EMG signals, extracting features such as Root Mean Square (RMS), Mean Absolute Value (MAV), and Variance. These features are then used to train a Random Forest Regression model to predict joint angles, enhancing exoskeleton movement accuracy. The results demonstrate that the combination of the MAV feature and Random Forest Regression achieved the highest accuracy, with an RMSE of 12.197 and an R² of 91.6%. The exoskeleton system successfully predicts and follows the patient’s intended movements, providing real-time adjustments based on EMG data. This innovation is expected to improve the rehabilitation process for stroke patients by offering personalized, precise movement control. With further development, this system has the potential to significantly enhance the effectiveness of upper limb rehabilitation.

Abstract

Body temperature is an important parameter in medical diagnosis. Thermogun, a non-contact temperature measuring device based on infrared technology, needs to be calibrated periodically to maintain measurement accuracy. This study aims to design a Thermogun calibrator with FUZZY-PID control that uses water as a temperature stabilizer. This system is designed to maintain temperatures in the range of 32°C to 45°C. Testing of the device was carried out using the DS18B20 sensor, as well as the Arduino Mega 2560 microcontroller as the main controller, heater plate for heating and using the Nextion LCD for its display. The test results showed that the system was able to increase the speed of temperature increase with a low level of measurement error (error). From the results of the module data analysis on the standard thermometer, the temperature error using the standard thermometer was 0% at all settings between 32°C-45°C. from the module to 3 Thermoguns using FUZZY-PID control In the experiment conducted, it was found that thermogun 3 had a good average reading of all temperatures that had been measured on the module with an error between the largest 0.625% at various temperature settings. Then on thermogun 1 & 2 had a fairly large error of up to 3.15%. From the measurement results, it can be concluded that FUZZY-PID control can be used as a temperature stability control on a thermometer calibrator. This study succeeded in achieving the desired temperature with accurate accuracy and the tool functioned properly.
