Abstract

Pengembangan alat diagnostik berbasis IoT yang akurat dan terjangkau sangat penting untuk memajukan layanan kesehatan. Penelitian ini bertujuan untuk mengevaluasi kinerja alat Diagnostic Pocket dalam mengukur suhu tubuh, saturasi oksigen (SpO₂), dan denyut jantung (BPM) dengan membandingkannya terhadap alat standar (thermogun dan pulse oximeter). Sebanyak 54 subjek dilibatkan dalam studi perbandingan ini. Analisis statistik dilakukan menggunakan uji paired t-test atau Wilcoxon signed-rank test untuk signifikansi perbedaan, analisis Bland-Altman untuk menilai tingkat kesepakatan, dan korelasi Pearson/Spearman untuk kekuatan hubungan. Hasil penelitian menunjukkan bahwa Diagnostic Pocket memiliki kinerja yang baik dalam mengukur SpO₂ dan BPM, dengan tingkat kesepakatan dan korelasi yang memadai terhadap alat standar. Namun, untuk pengukuran suhu, alat ini masih menunjukkan perbedaan yang signifikan secara statistik dan kesepakatan yang rendah. Disparitas pada pengukuran suhu diduga disebabkan oleh perbedaan sensitivitas sensor, kalibrasi, atau lokasi pengukuran. Variasi pada BPM mungkin dipengaruhi oleh kondisi fisiologis subjek. Simpulannya, Diagnostic Pocket menjanjikan untuk pemantauan SpO₂ dan BPM, namun diperlukan penyempurnaan lebih lanjut pada komponen sensor suhunya.

Abstract

The ability to detect hearing impairment early is an important aspect of preventive efforts in the field of ear and hearing health. An audiometer is a device used to measure a person's hearing threshold by presenting sound stimuli at various frequencies and intensities. This research aims to design and build a simple digital audiometer that can be used as a means of early hearing screening at primary healthcare facilities. The developed audiometer system uses a microcontroller as the control center, equipped with a user interface based on an LCD screen and buttons for adjusting frequency and sound intensity. Sound output is channeled through headphones and calibrated within the frequency range of 125 Hz to 10,000 Hz with intensity levels from 0 dB to 10 - 100 dB. The value obtained from the measurements after making improvements on TP 1 (Input adapter) showed an error of 0.03% TP 2 (Nextion LCD input) at 5.12 V which is still within tolerance. TP 3 (Arduino Input) at 11.64 V which is still within tolerance. TP 4 (Input IC LM2956) at 11.66 V which is still within tolerance. The function of this audiometer tool was tested using a digital multimeter. The highest error value is at a frequency of 500 Hz, which is 0.152%. This is partly due to the tolerance values of the components used. Based on the data collection using a sound level meter, the furthest difference in sound intensity values at the point of 40 dB was found to be 3.46 dB. This is due to the influence of noise in the surrounding measurement area.

Abstract

A Blood Type Detector is an electronic device used to detect human blood types. Blood type detection and observation are generally carried out through a series of experiments on blood samples, namely antiserum reactions (anti-A, B, AB, and D). Currently, determining a person's blood type is still done manually. This will certainly be complicated and require extra attention if the blood sample to be tested is quite large in number, it will take a lot of time and is inefficient. The purpose of research on a Blood Type Detector Tool with an Arduino Uno-Based Color Sensor is to improve the efficiency, accessibility, and quality of health care as a whole. As well as ease of access and data processing for users. This tool is designed using a Color Sensor so that it can detect the occurrence of agglutination or non-agglutination reactions from blood samples that have been mixed with antigens. The working system settings of this tool are based on Arduino Uno, the results of which will be displayed on the LCD, then a sound will appear from the results of the blood type being read. In the blood type test function test process, a blood sample and antigen are required, where the blood sample and antigen are mixed together, the ratio is one drop of blood with one drop of antisera, then stirred together, so that agglutination or non-agglutination occurs in the blood sample that has been mixed with the antigen. After sampling, the blood type tester will detect the four blood samples dropped onto the sample card. When the blood sample in anti-A and AB coagulates, the sensor will read a value of >200 for blood type A.
