Abstract

Radiasi ultraviolet (UV) dan panas akibat paparan sinar matahari dapat memengaruhi kinerja bilah turbin angin, khususnya pada material polimer untuk aplikasi luar ruangan. Penelitian ini bertujuan menganalisis pengaruh radiasi UV terhadap respons termal dan mekanik pada bilah turbin angin sumbu vertikal Savonius airfoil shaped blade FX 74-CL5-140 berbahan Polylactic Acid (PLA), Acrylonitrile Butadiene Styrene (ABS), dan Polyethylene Terephthalate Glycol (PETG). Analisis dilakukan menggunakan Computational Fluid Dynamics (CFD) dengan solar radiation dan Static Simulation pada variasi sudut putar 0°, 30°, 60°, dan 90° untuk mengevaluasi distribusi temperatur, tegangan Von-Mises, dan total deformation. Hasil simulasi menunjukkan bahwa temperatur maksimum tertinggi diperoleh PLA sebesar 52.33°C, diikuti ABS 52.16°C, dan PETG 51.22°C. Tegangan Von-Mises maksimum tertinggi diperoleh PLA sebesar 7.361 MPa, diikuti PETG 5.768 MPa, dan ABS 4.237 MPa. Sementara itu, deformasi maksimum tertinggi diperoleh PLA sebesar 1.079 mm, diikuti ABS 1.034 mm, dan PETG 0.961 mm. Berdasarkan keseluruhan analisis menggunakan metode Multi Criteria Decision Making (MCDM) dengan TOPSIS, material ABS dipilih sebagai material paling optimal untuk bilah turbin angin vertikal Savonius airfoil shaped blade FX 74-CL5-140 yang digunakan di luar ruangan dengan paparan radiasi matahari.
