Abstract

Heart is a vital organ in the human body. The heart functions circulated the blood throughout the body. The volume of blood in a body organ will vary due to blood pumping by the heart. Photoplethysmograph (PPG) is a device that can detect changes in blood volume using optical sensors. The purpose of this research is to make Photoplethysmograph monitoring system online. That is a device to monitor blood volume changes and display the change graph. Fluctuations in blood volume changes are influenced by the rhythm of blood pumping by the heart. Each peak on the PPG signal is correlated with one heartbeat. Photoplethysmograph charts can be used to determine the condition and abnormalities of a person's heart. Photoplethysmograph system online is realized in the form of sensors, amplifiers, LPF, ADC, and microcontroller as a serial interface, wiz610wi module, and web applications as online PPG graph viewer. Sensors composed of red LED and photoresistor (LDR) are placed on the fingers. The rays emitted by the LEDs are received by the LDR. The signals received by the LDR vary according to the volume of blood changes. The sensor output signal is then amplified and filtered. Incoming filter output signal ADC, serial interface by AT89C2051 then by wiz610wi module transmitted for display and monitored. Obtained Devices and apps created have worked well. The signal shown is pretty good, clean of noise. Transmission distance measured up to 70 m with delay less than 200 ms. The average heart rate calculation was in error 3%

Abstract

To stir and homogenize chemical solutions and other liquid substances, a magnetic stirrer is required. This study aims to create a magnetic stirrer device with three speed levels based on the Arduino Uno microcontroller. This stirrer tool is made up of a DC motor, a Microcontroller with the IC ATmega 328P, a speed control circuit, a buzzer, and an LCD display. The IC controller will initialize commands to the LCD circuit and the speed control circuit when the device is turned on, according to the tool's working principle. When the set timer button is pressed, the speed set menu appears; on the speed set menu, press the high, low, and normal buttons to select the speed.The motor's speed is controlled using the PWM principle, which involves setting the duty cycle to 25% (Low) for low speeds where the voltage supply to the DC motor is 1.25 volts, 60% for medium speed (Normal) where the voltage supply is 3 volts, and 100% for high speed (High) where the voltage supply is 5 volts. Then press the Start button to begin stirring. If the motor is turned on, the tool will run for a predetermined time ranging from 1 to 15 minutes. Then, press the required speed start button. Then, press the start button to begin stirring; if the motor runs, the stirrer tool will run for the duration specified. To determine the speed of a DC motor at low speeds. Low speed DC motor speed measurements yielded a speed of 2673 rpm, normal speed yielded a speed of 3294 rpm, and high speed yielded a speed of 4438 rpm. The buzzer will sound when the stirring process is complete.

Abstract

Chronic kidney disease (CKD) patients, especially those with hemodialysis, frequently struggle with mental health issues like anxiety and depression. Psychotherapy has been known to treat psychological problems, but its effectiveness in managing CKD patients is still rarely scientifically proven. The aim of this study was to analyze the role of psychological treatments in improving the mental health of CKD patients with hemodialysis. We comprehensively reviewed the related studies published in PubMed, Google Scholar, ScienceDirect, and Clinical Key over the last ten years, up to June 7, 2023. A keyword combination was used in the search engine strategies, and all articles about CKD patients receiving hemodialysis and psychotherapy were included. Based on the eligibility criteria, 716 patients were included in 13 out of 18,830 studies in the final analysis. Psychological problem was complained by 399 CKD patients. The psychotherapy included cognitive behavioral therapy (reported in four studies, n=4), diaphragmatic breathing relaxation (n=1), meditation (n=1), hypnotherapy (n=1), Kidney Optimal Health Program (KOHP) (n=1), psychological intervention (n=1), murottal Al-Qur'an therapy (n=3), and spiritual therapy (n=1). These interventions were performed once to four times a week, for ten minutes to five hours during hemodialysis for two to ten weeks. Meditation and KOHP showed no significant improvement in anxiety and depression. The remaining psychotherapies significantly improved the quality of life by reducing anxiety and depression in hemodialysis patients and enhancing sleep quality, self-esteem, hopefulness, medication adherence, and physical condition. In conclusion, psychotherapy should be considered in an interdisciplinary team to treat CKD patients comprehensively. Further studies are still necessary to determine the efficacy of each psychological intervention in CKD patients with psychiatric problems.

Abstract

Indonesia, an archipelagic country located along the equator, is highly vulnerable to natural disasters. At the same time, its geographical conditions require reliable telecommunications to strengthen connectivity across its many islands. One effective solution is the utilization of High-Frequency (HF) communication technology, which enables long-distance communication and supports broadcasting-based telecommunications. This approach can expand available frequency channels, making HF radio communication an important tool for disaster-prone regions like Indonesia. To optimize HF communication, researchers have developed various models of HF channel radio systems, often represented statistically and implemented through channel simulators. Among these approaches, the Auto Regressive Integrated Moving Average (ARIMA) model has been identified as particularly suitable. This is because ARIMA can handle the non-stationary characteristics of time-series data, such as those found in HF channel attenuation measurements. In the modeling process, several ARIMA configurations were tested, including ARIMA (0,1,1), (0,0,5), (1,0,0), (1,0,1), (1,0,2), and (0,0,4). From these options, two models—ARIMA (1,0,0) and ARIMA (1,0,2)—showed the closest fit to the observed data. The final selection was made using the Akaike Information Criterion (AIC), where the ARIMA (1,0,2) model emerged as the best. This model provides the most accurate representation for predicting HF channel attenuation, supporting more reliable telecommunications systems for Indonesia.

Abstract

This research developed a water quality monitoring system using fuzzy logic and an ESP8266 microcontroller with temperature, humidity, pH, and Total Dissolved Solids (TDS) sensors. The system processes data in real time by converting sensor values ​​into linguistic categories, then produces water quality that meets WHO standards. The system is also connected to an IoT platform to facilitate remote monitoring. Simulation results show that the system is able to recognize overlapping water conditions, for example, at pH 7.5 which falls into the "Good" and "Medium" categories simultaneously with different weights. With sensor conditions of 28°C temperature, 65% humidity, pH 7.5, and TDS 400 mg/L, the system produces a quality score of 12.6, indicating excellent water quality. Field testing and comparison with laboratory results show an accuracy level of up to 92%. Fuzzy logic has proven to be more reliable than simple threshold methods, especially when conditions change rapidly or sensors experience shifts. However, the system's results are highly dependent on sensor calibration and regulations need to be adjusted to standards in each region. The computational limitations of the ESP8266 also mean that fuzzy processing must be done on a computer or in the cloud.
