Aktivitas berjalan pada manusia menyimpan energi kinetik yang bisa dimanfaatkan sebagai sumber energi alternatif terbarukan. Salah satu metode yang terbaru ini dilakukan adalah mengubah energi kinetik pada gerak berjalan manusia menjadi energi listrik dengan menggunakan material piezoelectrik dan prinsip elektromagnet yang dapat dikenakan di lutut, sepatu atau di lantai sebagai permukaan pijakan berjalan. Pada Tugas Akhir ini dianalisa potensi dari energi kinetik pada gerak berjalan manusia yang ditunjukkan dengan pola gerak berjalan serta gaya reaksi permukaan pijakan kaki. Potensi energi kinetik pada gerak berjalan manusia didapatkan dengan menganalisa kinematika-kinetika gerak berjalan manusia menggunakan prinsip vektor dan hukum newton tentang gerak. Di dalam memodelkan gerak berjalan manusia ini dilakukan pengamatan gerak berjalan menggunakan kamera video yang diletakkan pada sisi samping (saggital plane) sehingga didapatkan data koordinat posisi x,y dari 13 titik segmen pada bagian tubuh. Pengambilan data dilakukan terhadap tiga orang laki-laki normal dengan tinggi rata-rata 176.67m, massa rata-rata 60.33kg dilakukan dua kali percobaan. Data yang diperoleh ini digunakan sebagai inputan untuk mendapatkan pola gerak berjalan yang ditunjukkan dengan lintasan perpindahan posisi, kecepatan dan percepatan linier serta perubahan sudut, kecepatan sudut, percepatan sudut dari pusat massa dari tiap bagian tubuh. Kemudian dari data ini dapat dilakukan perhitungan gaya reaksi permukaan pijakan kaki. Dari Tugas Akhir ini didapatkan: pola gerak berjalan (posisi, kecepatan, percepatan linier dan sudut), hubungan antara gerak berjalan dengan gaya reaksi permukaan pijakan kaki manusia. Hasil Tugas Akhir ini dapat digunakan sebagai dasar rancang bangun pembangkit listrik tenaga gerak berjalan manusia.


Human walking Activity have kinetic energy that can be used as a source of renewable alternative energy. One of the methods is transform kinetic energy of human walking motion into electricity by using the material piezoelectric and elektromagnet principles that can be used on the knee, shoes on the floor or footing as a walking surface. This final project is analyzed potential of kinetic energy of human walking motion that indicated by human gait and reaction force of surface feet. Potential of kinetic energy of human walking is obtained by analyzing kinematic-kinetic human walking using the principles of law and the Newton vector of motion. Modeling motion of human walking observation was conducted using video camera placed on the side (saggital plane) so that the data obtained coordinate position x, y point of 13 segments in the body. The data carried out on three men with high normal average 176.67m, the mass average 60.33kg experiment performed twice. The data obtained is used as input to get the motion pattern is shown with a walking track motion position, velocity and acceleration linier and changes angle, angle speed, angle acceleration of the center of mass of each body part. Then the data from this calculation can be done reaction force of surface feet. End of this final project was found: gait or walking motion pattern (linier angle position, speed and acceleration), the relationship between gait with the reaction force of surface feet. End result of this final project can be used basic design of harvesting of human motion.
