EVALUASI GERAK JATUH DAN JONGKOK DENGAN MENGGUNAKAN SISTEM PENDETEKSI JATUH BERBASIS SENSOR ACCELEROMETER
Abstrak
Pada penelitian ini, sensor accelerometer digunakan sebagai sistem pendeteksi jatuh secara Wireless, Wearable dan Ambulatory guna mengevaluasi pergerakan berdiri-jatuh dan siklus berdiri-jongkok. Sistem ini terdiri dari dua bagian yaitu bagian pengirim dan bagian penerima yang masing-masing dilengkapi sistem komunikasi wireless, dengan frekuensi radio 2,4GHz untuk mengirimkan data accelerometer antara kedua bagian tersebut. Sensor accelerometer diletakkan pada bagian pengirim untuk mendeteksi nilai tiga sumbu percepatan gravitasi dan nilai magnitude pada saat terjadi jatuh dan jongkok melalui pengolah data kontroler ATMEGA328. Sistem pengirim ditempatkan pada pinggang naracoba untuk diuji dalam mendeteksi posisi jatuh ke depan, ke belakang, dan siklus berdiri-jongkok. Dari hasil pengujian pada 10 orang naracoba didapatkan bahwa karakteristik tiga sumbu pada posisi jatuh ke depan bernilai 0,123g, -0,473g, -0,888g, ke belakang bernilai -0,084g, 0,495g, 0,628g, dan jongkok bernilai -0,739g, -0,262g, -0,493g. Adapun nilai rata-rata magnitude pada jatuh ke depan bernilai 2,916g, ke belakang bernilai 2,580g, dan jongkok bernilai 0,344g.
