Abstract

Cidera ligamen anterior cruciatum (ACL) merupakan salah satu cidera yang umum terjadi pada atlet dan sering kali memerlukan tindakan rekonstruksi dengan bantuan interference screw (IFS). Material yang digunakan dalam pembuatan IFS memiliki peranan penting dalam menentukan keberhasilan fiksasi. Penelitian ini bertujuan untuk menganalisis tegangan dan distribusi beban pada IFS berbahan titanium alloy menggunakan pendekatan Finite Element Analysis (FEA) dengan perangkat lunak Ansys. Desain IFS direkayasa ulang berdasarkan produk Smith & Nephew dengan dimensi panjang 25 mm dan diameter 9 mm. Simulasi dilakukan pada dua skenario pembebanan, yaitu torsi sebesar 2000 N.mm dan gaya tarik (pullout) sebesar 200 N. Hasil simulasi menunjukkan bahwa tegangan maksimum pada pengujian torsi adalah sebesar 41,021 MPa dengan deformasi 0,108 mm, sedangkan pada pengujian pullout sebesar 42,628 MPa dengan deformasi 0,095 mm. Nilai tegangan yang dihasilkan masih jauh di bawah batas yield strength material titanium alloy (930 MPa), yang menunjukkan bahwa desain dan material IFS mampu menahan beban kerja yang disimulasikan. Dengan demikian, penggunaan titanium alloy sebagai material IFS dinilai layak dan efektif secara mekanis berdasarkan hasil simulasi ini.

Abstract

The research aims to design and develop an electric wheelchair based on the Arduino Uno microcontroller as a mobility solution for individuals with disabilities. A conventional wheelchair was modified by integrating an electric drive system controlled by an analog joystick, which is connected to the Arduino Uno and DC motors via a BTS 760 motor driver. The wheelchair design complies with ISO 7176-5 standards and is adapted to the anthropometric dimensions of Indonesian users. Test results indicate that the control system functions effectively, allowing responsive control of wheelchair movements forward, backward, left, and right according to joystick operation. However, several challenges were encountered during the chain adjustment and gear welding processes, requiring further development to achieve optimal performance. This study demonstrates that utilizing the Arduino Uno as the central control unit enables the production of an electric wheelchair at a more affordable cost.
