Abstract

Penelitian ini bertujuan untuk merancang dan mengembangkan sepeda statis ergonomis yang mempertimbangkan parameter antropometri pengguna serta kekuatan struktural rangka. Metode yang digunakan adalah Research and Development (R&D) dengan pendekatan rekayasa produk, meliputi tahap perancangan model 3D, simulasi numerik, fabrikasi, dan pengujian pembebanan. Material rangka menggunakan baja hollow 40×60 mm dengan sistem pembebanan kampas rem. Analisis kekuatan struktur dilakukan menggunakan Software SolidWorks Simulation dengan beban desain maksimum 150 kg. Parameter yang dianalisis meliputi tegangan Von Mises, displacement, dan faktor keamanan. Hasil simulasi menunjukkan bahwa tegangan maksimum berada di bawah batas luluh material dengan faktor keamanan >1. Pengujian pembebanan langsung menggunakan massa pengguna ±100 kg tidak menunjukkan deformasi permanen maupun kegagalan struktural sehingga desain dinyatakan layak. Kesimpulannya, desain sepeda statis yang dikembangkan memenuhi standar ergonomi, mampu menahan beban pengguna, dan aman digunakan sebagai alat olahraga dalam ruangan. ***** This research aims to design and develop an ergonomic stationary bicycle by integrating anthropometric parameters and structural strength considerations into the product development process. The study adopts a Research and Development (R&D) approach with an engineering-based workflow consisting of 3D modeling, numerical simulation, fabrication, and load testing. The bicycle frame is constructed from 40×60 mm mild steel hollow square tubes and equipped with a mechanical felt-pad resistance system. Structural analysis was performed using SolidWorks Simulation under a maximum design load of 150 kg. Key evaluation parameters include Von Mises stress, displacement, and factor of safety. The simulation results show that the maximum stress remained below the material yield strength and produced a factor of safety greater than one. Direct load testing with a user weighing approximately 100 kg showed no permanent deformation or structural failure, confirming the feasibility of the design for actual operation. It is concluded that the developed stationary bicycle meets ergonomic requirements, supports user load safely, and is suitable for indoor exercise applications
