Penelitian ini bertujuan untuk melakukan studi kekuatan rangka mesin pengayak biji kopi menggunakan pendekatan simulasi Finite Element Analysis (FEA). Analisis dilakukan untuk mengetahui respons mekanik struktur terhadap pembebanan statis berdasarkan parameter tegangan, regangan, deformasi, dan faktor keamanan. Model rangka dibuat menggunakan Computer Aided Design (CAD) dengan material ASTM A36 dan dianalisis pada tiga variasi profil hollow, yaitu 40×40×1,8 mm, 35×35×1,8 mm, dan 40×40×2,0 mm. Pembebanan statis sebesar 560 N diberikan berdasarkan total massa komponen mesin. Hasil simulasi menunjukkan bahwa nilai tegangan maksimum yang diperoleh berada pada rentang 16,404–17,460 MPa, nilai regangan sebesar 0,000071–0,000121, deformasi sebesar 0,206–0,301 mm, dan faktor keamanan sebesar 4,9–9,1. Seluruh nilai tegangan yang diperoleh masih berada di bawah tegangan luluh material ASTM A36 sebesar 250 MPa sehingga struktur rangka masih berada dalam kondisi aman terhadap pembebanan yang diberikan. Hasil penelitian menunjukkan bahwa variasi dimensi profil memengaruhi respons mekanik struktur, namun seluruh model yang dianalisis memenuhi kriteria kekuatan dan keamanan berdasarkan parameter tegangan, regangan, deformasi, dan faktor keamanan.
