Alat Pendeteksi Efek Membaca Ayat Suci Al-Qur’an terhadap Saturasi Oksigen dan Denyut Nadi dengan Menggunakan Sensor MAX30102 Berbasis Internet of Things (IoT)

Abstract

Reading the Qur'an is one of the recommended practices to remember Allah SWT and Rasulullah SAW. The tool to detect the effect of reading the Qur'an on oxygen saturation and pulse rate using the MAX30102 sensor is made based on the Internet of Things (IoT) in order to motivate people to diligently read the Qur'an. The sound detected by the MAX9814 sensor and good breathing while reciting the Quran may increase oxygen saturation. The tool is designed to be able to detect the effect of reading the Qur'an on oxygen saturation and pulse rate using the MAX30102 sensor based on real time with RTC DS3231 whose sensor readings can be stored using an SD Card, displayed on a 16x2 LCD screen, and sent to the internet so that it can be viewed via an SD card. blynk application on mobile. The touch of a finger to the MAX30102 sensor will allow the sensor to sense blood flow in the finger and read changes in output voltage which are processed on the ATmega328 microcontroller and then converted into heart rate (bpm) and oxygen saturation (%). Sensor reading data will also be saved to a file with the SD card module and displayed based on the actual time on the 16x2 LCD. The test was carried out by measuring the pulse/heart rate and oxygen saturation values for 5 students majoring in Physics-D3 2019 FMIPA USU. The measurement time for pulse/heart rate and oxygen saturation was done 5 minutes before reading the Qur'an, 5 minutes while reading the Qur'an, and 5 minutes after reading the Qur'an. After the measurement, it was found that the decrease in value with an average decrease in pulse/heart rate before reading the Qur'an and after reading the Qur'an was 12.08%. While the oxygen saturation obtained an increase in value with an average increase before reading the Qur'an and after reading the Qur'an is 1.69%. From the results of this study obtained error values for measuring pulse/heart rate and oxygen saturation of 7.06% and 0.67%, this indicates that the MAX30102 sensor is good enough to be used to determine the effect of reading the Qur'an on oxygen saturation and pulse.
