ABSTRAK
Penyakit jantung merupakan salah satu penyakit yang berbahaya dan banyak ditemui pada manusia, penyembuhan atau terapi bagi pengidap penyakit jantung cukup rumit diantaranya kondisi jantung harus dikontrol sesering mungkin berikut dengan melihat kemajuan perkembangannya membaik atau memburuk. Jika proses kontrol perkembangan kesehatan jantung terhambat, tidak jarang penyakit jantung berlanjut ke serangan jantung dimana serangan jantung termasuk kondisi mematikan.
Dari kendala yang disebutkan diatas maka dikembangkan suatu sistem monitoring keadaan kesehatan jantung pasien dengan metode analisis hamburan cahaya yang dipantulkan oleh kepadatan aliran darah serta mampu mentransmisikan data melalui jaringan Internet of Things (IoT), sistem pendeteksi menggunakan sensor cahaya dimana setiap perubahan aliran darah dari denyut nadi akan merubah intensitas cahaya yang diterima pada sensor cahaya, dari proses ini dilakukan kalkukasi interval waktu setiap perubahan intensitas cahaya sehingga hasil akhir diperoleh nilai denyut nadi dalam satuan menit yang siap di transmisikan melalui jaringan Internet of Things(IoT).
Setelah melakukan implementasi dan analisis didapatkan kesimpulan akurasi sensor detektor sinyal dengan nilai 95,7%. Akurasi pembacaan data minimum Analog to Digital Converter sebesar 99,4%. kemudian akurasi pembacaan data maksimum Analog to Digital Converter adalah 99,7%. Untuk koneksi Interenet of Things dilakukan pengujian jitter berdasarkan data dan didapatkan hasil sebesar 0,0756 detik pada kondisi Message Queue Telemtry Transport (MQTT) Broker online.
ABSTRACT
Heart disease is one of the most dangerous diseases and is commonly found in humans, cures or therapies for people with heart disease is quite complicated, such as heart conditions should be controlled as often as possible following the progress of development progressively improved or worsened. If the process of controlling the development of heart health is inhibited, not infrequently the heart disease continues to heart attack where the heart attack including the deadly condition.
From the above mentioned constraints developed a system monitoring the state of heart health of patients with light scattering analysis method reflected by the density of blood flow and capable of transmitting data through the Internet of Things (IoT) network, detection system using light sensor where any change of blood flow from the pulse will change the intensity of light received at the light sensor, from this process is calculated the time interval of each change of light intensity so that the end result is the value of the pulse in units of minutes ready to be transmitted through the Internet of Things (IoT) network.
After doing the implementation and analysis got the conclusion of accuracy of signal detector with the value of 95,7%. Accuracy of Analog to Digital Converter minimum reading is 99.4%. then the maximum reading accuracy of Analog to Digital Converter is 99.7%. For Interenet of Things connection is done jitter test based on the data and obtained the result of 0.0756 seconds in the condition of Message Queue Telemtry Transport (MQTT) Broker online.
