Penderita diabetes melitus berisiko tinggi mengalami amputasi pada bagian kaki akibat komplikasi luka kronis. Amputasi bawah lutut, terutama pada pasien diabetes, berdampak pada penurunan kualitas hidup karena terbatasnya mobilitas dan kemandirian. Penelitian ini bertujuan merancang kaki palsu ergonomis dengan pendekatan antropometri untuk meningkatkan kenyamanan dan fungsi gerak pasien pasca-amputasi. Data antropometri diperoleh dari 100 pasien (50 laki-laki dan 50 perempuan) di Klinik Pratama Universitas Syiah Kuala. Analisis dilakukan melalui uji keseragaman, kecukupan, kenormalan, perhitungan persentil dan pembuatan size chart sebagai ukuran untuk mendesain kaki palsu. Sebagai referensi perbandingan, dilakukan benchmarking terhadap dua produk, yaitu Kaki Palsu OSSUR Cheetah Xpolore High Performance Prosthetic dan Kaki Palsu Bawah Lutut – Kurnia Putra Ortopedi. Hasil benchmarking digunakan untuk mengevaluasi aspek teknis dan ergonomis sebagai dasar perbaikan desain. Berdasarkan hasil tersebut, dikembangkan tiga kategori ukuran kaki palsu, yaitu kecil (S), sedang (M), dan besar (L), agar sesuai dengan variasi tubuh pasien secara lebih akurat. Rancangan kaki palsu ini terdiri dari lima komponen utama: socket berbahan carbon fiber, shank dari pylon aluminium, ankle-foot bertipe multiaxial foot, pengait buckle fastener, dan baut dari stainless steel. Komponen tersebut dirancang untuk menunjang kenyamanan, stabilitas, dan fleksibilitas gerak pasien. Desain akhir dimodelkan menggunakan software Autodesk Inventor dengan mempertimbangkan aspek ergonomi dan kenyamanan jangka panjang. Hasil rancangan ini diharapkan menjadi solusi prostetik yang lebih adaptif, fungsional, dan sesuai kebutuhan pasien diabetes di Indonesia.

Diabetes mellitus significantly increases the risk of lower-limb amputation due to chronic wound complications, particularly affecting the feet. Below-knee amputation in diabetic patients often leads to a decline in quality of life due to limited mobility and independence. This study aims to design an ergonomic prosthetic leg using an anthropometric approach to improve comfort and mobility for post-amputation patients. Anthropometric data were collected from 100 patients (50 males and 50 females) at Klinik Pratama, Universitas Syiah Kuala. The data were analyzed through uniformity, adequacy, and normality tests, percentile calculations, and the development of a size chart to serve as the basis for prosthetic design. For comparison, benchmarking was conducted on two existing products: the OSSUR Cheetah Xpolore High Performance Prosthetic and the Below-Knee Prosthetic by Kurnia Putra Ortopedi. The benchmarking results were used to evaluate technical and ergonomic aspects as a foundation for design improvements. Based on the analysis, three prosthetic leg size categories were developed—small (S), medium (M), and large (L)—to better match patient body variations. The prosthetic design consists of five main components: a carbon fiber socket, an aluminum pylon shank, a multiaxial ankle-foot, a buckle fastener, and stainless steel bolts. These components are designed to support patient comfort, stability, and movement flexibility. The final design was modeled using Autodesk Inventor software, considering ergonomic principles and long-term comfort. The resulting prosthetic is expected to offer a more adaptive, functional solution tailored to the needs of diabetic patients in Indonesia.
