Penelitian ini bertujuan menganalisis kekuatan struktur boom pada alat peraga EV (Electric Vehicle) Mini Excavator menggunakan metode Finite Element Analysis (FEA) berbasis SolidWorks Simulation. Objek penelitian berupa boom berbahan baja ASTM A36 dengan ketebalan 2,5 mm yang dianalisis melalui simulasi pembebanan statis menggunakan kombinasi gaya aktuator dan beban kerja maksimum. Parameter yang dievaluasi meliputi tegangan von Mises, displacement, dan factor of safety (FoS). Hasil simulasi menunjukkan tegangan von Mises maksimum sebesar 108,916 MPa, masih berada di bawah yield strength ASTM A36 sebesar 250 MPa, sehingga struktur tetap berada pada daerah elastis. Nilai displacement maksimum sebesar 0,434 mm menunjukkan deformasi yang sangat kecil dan tidak memengaruhi fungsi struktural boom. Nilai factor of safety minimum sebesar 2,295 berada di atas batas aman yang direkomendasikan untuk struktur alat berat. Tegangan maksimum terkonsentrasi pada area pangkal boom di sekitar lubang bearing sebagai lokasi konsentrasi tegangan akibat perubahan geometri. Berdasarkan hasil tersebut, desain boom pada alat peraga EV (Electric Vehicle) Mini Excavator dinyatakan aman terhadap pembebanan statis yang disimulasikan dan layak digunakan sebagai dasar pengembangan desain maupun penelitian lanjutan.
