Abstract
Penelitiaan tentang pengendalian kursi roda elektrik dengan sensor electromyograph (EMG) dapat membantu penyandang cacat, karena kursi roda elektrik tersebut mampu bergerak ke arah yang diinginkan hanya dengan menggerakkan otot tertentu. Namun hal tersebut terdapat kelemahan bagi penyandang cacat yang memiliki kekuatan fisik lemah yaitu memiliki respon yang lambat jika dibandingkan dengan orang normal, sehingga kemungkinkan orang tersebut tidak dapat mengendalikan kursi rodanya dengan baik yang berakibat kursi roda berpotensi membentur objek disekitarnya. Dalam Tugas Akhir ini akan dibuat sistem pengaman kursi roda elektrik berbasis sensor jarak dengan kendali sensor EMG. Penggunaan sensor jarak bertujuan agar ketika pengguna lalai kursi roda elektrik dapat terkendali sebelum menabrak objek disekitarnya.
Sensor jarak yang digunakan adalah sensor ultrasonik, sensor ini bekerja dengan memancarkan gelombang ultrasonik dan terpantul kembali ketika gelombang tersebut membentur suatu objek. Terdapat 6 buah sensor yang terpasang di sekeliling kursi roda. Jika sensor mendeteksi objek yang berjarak kurang dari 50 cm, maka mikrokontroler akan menghentikan kursi roda pada jarak aman. Pada pengujian sistem pengaman kursi roda yang dilakukan telah didapatkan jarak aman antara objek dengan sensor depan dan belakang adalah 40 cm, serta kanan dan kiri adalah 30 cm.

Research on the control of electric wheelchairs with Electromyography (EMG) sensors is able to help people with disabilities, because the electric wheelchair is able to move in the desired direction just by moving the specific muscles. But there are weaknesses for people with disabilities who have weak physical strength. People with weak physical strength have a slow response when compared with normal people, so it is possible that the person can not control the wheelchair spontaneously which result in a wheelchair hitting the object arround it. In this Final Task will be made an electric wheelchair safety system based range sensor with EMG control. The use of range sensor aiming when the user was careless the electrical wheel chair is under control before hitting the object arround it.
The range sensor which used is an ultrasonic sensor, this sensor works by reflecting an ultrasonic wave and reflected back when that wave hitting an object. There are 6 sensors mounted around the wheelchair. If the sensor detects an object less than 50 cm away, then the microcontroller will stop the wheelchair in the safe range. In the electrical wheelchair safety system tests conducted have been obtained the safe distance of the wheelchair with the front and rear sensor is 40 cm, also right and left sensor 30 cm.
