Abstract

Sejak tahun 2018 hingga 2022, data penyandang disabilitas semakin meningkat. Salah satu komponen disabilitas yang tertinggi adalah kesulitan dalam berjalan yang diakibatkan adanya gangguan anggota gerak bagian bawah akibat faktor penyakit dan cedera sendi yang terjadi pada atlet. Sehingga untuk mengatasi keterbatasan tersebut diperlukan alat bantu Ankle Foot Orthosis. Oleh karena itu, sangat penting untuk merancang orthosis dengan aspek biomekanis dan kenyamanan pengguna. Pada penelitian ini dilakukan dengan memberikan pengaruh perubahan massa struktur pada AFO jenis articulated dan non-articulated dan dilakukan simulasi untuk mengetahui respon dinamis yang terjadi. Dalam simulasi menggunakan software ANSYS Workbench dengan 3 modul sekaligus. Dalam merencanakan struktur AFO, menggunakan beban dinamis manusia berjalan dengan gait cycle. Selanjutnya akan dilakukan pembuatan prototype AFO dengan metode 3D printing berdasarkan desain optimum kenyamanan pengguna. Hasil yang didapatkan yaitu desain Articulated mempunyai tegangan dan deformasi yang lebih tinggi dibandingkan dengan non articulated, namun unutk tegangan per masing-masing sistem cenderung menurun dari ketebalan 2mm ke ketebalan 5mm, namun perlu diperhatikan terhadap aspek bobot. Desain akhir untuk Non-articulated adalah 3mm sedangkan untuk Non-Articulated adalah 4mm.

From 2018 to 2022, data on persons with disabilities has increased. One of the highest components of disability is difficulty in walking which is caused by disorders of the lower limbs due to disease and joint injuries that occur in athletes. So to overcome these limitations, an Ankle Foot Orthosis tool is needed. Therefore, it is very important to design the orthosis with biomechanical aspects and user comfort. This research was carried out by giving effect to changes in structural mass on articulated and non-articulated AFO types and a simulation was carried out to determine the dynamic response that occurred. In the simulation using ANSYS Workbench software with 3 modules at once. In planning the structure, using a dynamic load of a walking human with a gait cycle. Finally, the AFO prototype will be made using the 3D printing method based on the optimum design for user convenience. The results obtained, that Articulated designs have higher stresses and deformations compared to non-articulated, but for each system the stresses tend to decrease from 2mm to 5mm thick, but it is necessary to pay attention to heavy aspects. The final design for Non-articulated is 3mm while for Non-articulated it is 4mm.
