Abstract
Kursi roda elektrik merupakan salah satu alat bantu yang bisa digunakan untuk menunjang mobilitas seseorang yang mengalami kelumpuhan pada bagian kaki. Pada umumnya kontroller pada kursi roda elektrik menggunakan joystick. Tetapi penggunaan joystick sulit untuk orang yang telah lanjut usia dan orang yang menderita kuadriplegia. Oleh sebab itu dilakukan penelitian mengenai pengolahan sinyal elektromiografi (EMG) sebagai perintah kontrol untuk kursi roda elektrik. Sinyal EMG diakuisisi dengan menggunakan rangkaian instrumentasi EMG. Hasil sinyal yang didapatkan dari rangkaian instrumentasi lalu diproses oleh mikrokontroller dan dikirim ke laptop untuk memonitor sinyal otot dan memberikan perintah kontrol pada kursi roda elektrik. Hasil rata-rata persentase keberhasilan sistem untuk perintah kontrol maju sebesar 89.33 %, perintah kontrol belok kiri 97.33 %, belok kanan 97.33 %, dan berhenti 100 %.
