Abstract

Cardiovascular disease is a leading cause of global death, with early detection of heart rate anomalies key to preventing complications such as arrhythmias. However, conventional monitoring systems are often expensive, non-portable, and less accessible in remote areas. This study aims to develop an affordable and portable Internet of Things (IoT)-based heart rate monitoring system using the MAX30100 sensor and an ESP32 microcontroller. The system is designed to measure heart rate in real time, transmit data to the Blynk IoT platform, and provide automatic notifications when the heart rate is outside the normal range (60–100 beats per minute). The research methods include system design, hardware and software implementation, and testing on 10 subjects aged 20–40 years. Heart rate data was processed using a moving average filter to reduce motion noise. The test results showed heart rate measurement accuracy with an average relative error of 2.57%, an average data transmission latency of 1.39 seconds, and a notification response time of 1.8 seconds. The system is also power-efficient with a consumption of 80 milliamperes, making it suitable for long-term use. This research has successfully produced an efficient and accessible heart rate monitoring solution, supporting early detection of heart disorders in resource-limited settings.

Abstract

Single-phase induction motors are widely used in domestic and light industrial applications, but their performance is often affected by variations in power supply frequency, which affect rotor speed, torque, and energy efficiency. This study aims to analyze in depth the effect of frequency on the performance of a single-phase induction motor through an experimental approach, focusing on the relationship between frequency, rotor speed, torque, and energy efficiency. Tests were conducted on a 1 horsepower motor using a variable frequency drive at a frequency range of 30 to 70 hertz. Rotor speed (in revolutions per minute), torque (in newton-meters), and energy efficiency (in percent) were measured under no-load and mechanically loaded conditions. The results show that the rotor speed increases linearly from 820 revolutions per minute at 30 hertz to 1850 revolutions per minute at 70 hertz under loaded conditions. Torque peaks at 2.30 newton-meters at 50 hertz, while energy efficiency increases from 21.18% at 30 hertz to 40.00% at 70 hertz. This research provides a model of the relationship between frequency and motor performance that can be used to optimize motor operation in practical applications, especially to improve energy efficiency in the domestic and light industrial sectors.

Abstract

Starting an induction motor can lead to a substantial initial current surge, causing a voltage drop that may surpass permissible limits. This surge, known as starting current, is characterized by a sudden and high-value current that occurs during the operation of a transformer or motor. Therefore, it is imperative to implement a proper starting method for a 3-phase induction motor. This study focuses on a 10 hp or 7.5 kW induction motor and employs Matlab simulation to analyze the starting characteristics. The simulation results reveal that an increase in the source voltage correlates with a proportional rise in the starting current. Adjusting the source voltage entering the Autotrafo provides a means to regulate and reduce the magnitude of the starting current. In the case of direct starting, the simulation indicates a starting current of 108.5 A at a speed of 1476 rpm, contrasting with a normal current of 9.218 A at a speed of 1464 rpm. On the other hand, starting with the autotransformer method yields a starting current of 76.14 A at a speed of 1467 rpm, with a normal current of 9.078 A at a speed of 1424 rpm. This results in a notable difference in starting current of 32.36 A. Comparatively, direct starting generates the highest starting current, emphasizing the necessity to avoid this method to prevent rapid motor breakdown. The autotransformer method proves to be a more efficient alternative, showcasing a reduced starting current and providing a more reliable and sustainable approach to initiate the induction motor.

Abstract

The main problem in this research is a policy problem, namely the problem of legal policy in regulating the rules of legal certainty for health facilities. Therefore the approach to this problem is a policy-oriented approach. However, considering that the main target of this research is legislative policy in formulating legal certainty for health facilities in carrying out their duties and functions, the approach is mainly taken with a juridical-normative approach. This research was conducted at the Blangkejeren Public Health Center, Lhoksukon City, Central Aceh, with literature studies at the Panca Budi University Library and internet searches. The data sources of a research are primary data and secondary data. Because this research is a normative legal research, the sources studied are secondary data sources. Legal certainty of payment for health services has provided legal certainty to Health Service Providers (PPK) as regulated in Presidential Regulation Number 19 of 2016 concerning the Second Amendment to Presidential Regulation Number 12 of 2013 concerning National Health Insurance (JKN). However, this change still does not provide legal certainty for BPJS patients when problems occur related to the amount of payments that must be paid by BPJS to Health Service Providers, if there are patients who experience/require to be treated with costs that exceed the rates determined by BPJS. Legal consequences if there is no legal certainty for health services

Abstract

Automatic door opening system with facial recognition is an application that is widely used to improve security and comfort in various fields, such as offices, homes, and other limited areas. This study implements the Local Binary Pattern Histogram (LBPH) algorithm in an ESP32-based automatic door opening system integrated with an OV2640 camera. LBPH was chosen because of its superiority in recognizing faces even with varying lighting conditions and imperfect image quality. This system works by capturing facial images through an OV2640 camera, then processing the image using the LBPH algorithm to extract facial features. The results of facial recognition are then sent to the ESP32 which controls the automatic door locking system. In this implementation, the ESP32 is used as a microcontroller to connect the camera, data processing, and control the door actuator. Tests were conducted to measure the accuracy of facial recognition and system performance in opening the door. The test results show that the system can recognize faces with a high level of accuracy and open the door automatically in a short time, thereby increasing the efficiency and security of the system.
