Abstract

Rehabilitation methods for the physically disabled can be done by utilizing movement aids or prosthetics. However, most prosthetic fingers on the market only focus on aesthetic functions without paying attention to the function of finger mechanics so that not all people with disabilities who lose fingers can utilize various types of prosthetic fingers. The purpose of this research is to develop a prosthetic finger design to be more affordable for people with disabilities with a high level of accuracy and organization and produce prosthetic finger products that have good performance and strength, and in accordance with the needs and desires of users. This research involves experimental methods and iterative testing. The use of this prosthetic finger is limited to people with disabilities who have lost their fingers. The success in this research shows that the components used in the prosthetic finger function properly until the prosthetic finger can move effectively with a delay between the TTP223 touch sensor module and the finger moving 132 milliseconds to 148 milliseconds from 0 degrees to 180 degrees.

Abstract

Penelitian ini bertujuan untuk mengembangkan dan menganalisis desain prostetik jari tangan dengan mekanisme crosscable menggunakan material Polylactic Acid (PLA) melalui pendekatan Metode Elemen Hingga (FEM). Proses pemodelan dan simulasi dilakukan menggunakan software Autodesk Fusion 360 untuk mengevaluasi kinerja dan ketahanan desain sebelum pembuatan prototipe. Hasil simulasi menunjukan bahwa deformasi maksimal yang terjadi pada prostetik jari dengan beban 40 N adalah sebesar 0.299 mm, tegangan maksimal mencapai 6.484 MPa, dan regangan maksimal sebesar 0.05. faktor keamanan yang diperoleh adalah 8.00, yang melebihi batas minimum faktor keamanan sebesar 1.00. Berdasarkan hasil analisis ini, dapat disimpulkan bahwa desain prostetik jari berbahan PLA ini aman, fungsional, dan siap untuk fabrikasi, sehingga diharapkan dapat memberikan solusi yang lebih terjangkau dan ramah lingkungan untuk pengguna prostetik jari.
