Desain Dan Implementasi Sistem Telemedicine Untuk Periksa Kesehatan Mandiri Menggunakan Qr Code Authentication Berbasiskan Android

Abstract

Abstrak
Dalam mencegah penyebaran virus COVID-19, pasien dianjurkan untuk tidak pergi ke
fasilitas kesehatan kecuali dalam keadaan yang darurat. Pengaplikasian sistem telemedicine
untuk diagnosis dan monitoring kesehatan dari jarak jauh sangat dibutuhkan. Maka dari itu
Tugas Akhir berpusat pada desain dan implementasi sistem telemedicine untuk periksa
kesehatan mandiri dengan menggunakan aplikasi android “Self Checkupâ€. Sistem ini
dirancang menggunakan framework React Native untuk memeriksa kesehatan pengguna
dengan melihat data secara realtime dari tiga IoT healthcare device yaitu Weight Scale Device,
Body Temperature Device, dan IoT Healthcare Device melalui NodeMCU ESP32 dengan
protokol komunikasi Bluetooth Low Energy. Pairing antara aplikasi android dengan IoT
device menggunakan metode otentikasi dengan QR Code. Kemudian data yang diterima dari
IoT device dienkripsi dengan algoritma AES 256-bit lalu dikirimkan ke cloud server. Hasil
pengujian Quality of Service dari ketiga IoT healthcare device ke aplikasi android
memperoleh nilai rata-rata delay sebesar 97 ms, throughput sebesar 2.424 Kbps dan packet
loss sebesar 0%. Nilai rata rata delay dari aplikasi android ke cloud server sebesar 203 ms,
throughput sebesar 4.624 Kbps dan packet loss sebesar 0%. Hasil pengujian performansi
algoritma AES 256-bit memiliki rata-rata waktu enkripsi sebesar 54 ms dan dekripsi sebesar
72 ms.

Abstract
In preventing the spread of COVID-19, patients are advised not to go to health facilities except
in an emergency. Telemedicine system application for remote health diagnosis and monitoring
is urgently needed. Therefore, the final project focuses on the design and implementation of
the telemedicine system for independent health checks using the android application â€Self
Checkupâ€. This system was designed using the framework React Native to check the user’s
health by looking at the data in real-time from three IoT healthcare devices, which are Weight
Scale Device, Body Temperature Device, and electrocardiogram device through NodeMCU
ESP32 with Bluetooth Low Energy communication protocol. Pairing between the android
application and the IoT device is conducted by using an authentication method based on QR
code. Then the data received from the IoT device are encrypted with a 256-bit AES algorithm
before being sent to the cloud server. The quality of service (QoS) experiments from the three
IoT healthcare devices to the Android applications show that the average delay value is 97 ms,
throughput is 2.424 Kbps and packet loss is 0%. Meanwhile, the QoS experiments between the
Android application and cloud server show that the average delay is 203 ms, throughput is
4.624 Kbps and packet loss is 0%. As for the security performance of the 256-bit AES
algorithm, the average encryption is 54 ms and AES decryption is 72 ms.
