Abstract
Sendi lutut memiliki peranan yang sangat penting dalam mengakomodasi tegangan yang tinggi dengan tetap mempertahankan mobilitas dan stabilitas tubuh manusia. Pergerakan sendi lutut tersebut pasti mempunyai kecepatan. Akan tetapi kecepatan pergerakan sendi lutut tersebut sulit untuk kita ukur. Pada pengujian keausan sebelumnya, harga kecepatan diambil dari asumsi. Ada beberapa cara yang dapat dilakukan untuk melakukan pengukuran kecepatan. Dalam melakukan pengukuran tersebut, digunakan beberapa metode antara lain menghitung secara manual, menggunakan alat ukur seperti tachometer dan lain-lain. Pada tugas akhir ini dilakukan metode pengukuran kecepatan melalui perantara kamera digital. Analisa dilakukan dengan mengambil gambar suatu gerakan dari orang yang sedang berjalan diatas treadmill yang diberi titik pada tiap persendian pada kaki orang tersebut dan diatur kecepatannya. Yang menjadi acuan bahwa orang tersebut bergerak, yaitu titik tersebut mengalami perpindahan posisi. Dari data perpindahan tersebut akan diproses menjadi data kecepatan dan percepatan. Dari hasil penelitian didapatkan kecepatan kumulatif, kecepatan sudut pada tibia, kecepatan sudut femur, percepatan sudut tibia serta percepatan sudut pada femur pada saat melakukan aktivitas berjalan, berlari, menaiki, dan menuruni tangga.
