Abstract

The amount of waste from used tires in Indonesia continues to grow each year. Since used tires are challenging to decompose, various efforts are being made to repurpose and reduce this waste. One such solution involves using a tire shredder machine, which breaks down tires into smaller pieces, making them easier to recycle or use as raw materials in various industries. This machine helps mitigate the environmental impact of used tires by preventing them from accumulation. The components for developing this machine are readily available, and it features a user-friendly system that is easy to operate. The manufacturing process of the tire shredder machine involves several steps: material and tool preparation, measurement, cutting, welding, turning, drilling, and time management. Once assembled, the production cost (HPP) and production time are calculated. A test run is then performed to ensure the machine achieves the desired shred size. The machine frame is constructed from hollow steel (50 x 50 x 2 mm). Based on the calculations, the production cost (HPP) amounts to IDR 19,882,976.31, with a total production time of 225.86 seconds.

Abstract

The shaft is a crucial component in mechanical systems because it serves to transfer power and rotational motion throughout the machine. This research aims to assess the structural strength and operational performance of shafts used in a tire shredding machine through numerical simulation methods in order to achieve a safe and efficient design. The study involved several stages, including the development of shaft geometry models, the determination of boundary conditions, load application, mesh generation, and stress analysis using the finite element method. Two shaft configurations were examined: a 59 mm diameter shaft made from AISI 1045 steel and a 49 mm diameter shaft manufactured from ASTM A36 steel. The simulation results indicate that the 59 mm shaft experiences a Von Mises stress of 8.9 × 10⁻⁵ MPa, with a maximum displacement of 0 mm and a safety factor of 15. Similarly, the 49 mm shaft shows a Von Mises stress of 8.4 × 10⁻⁵ MPa, no measurable displacement, and a safety factor of 15. These findings confirm that both shaft designs are capable of safely withstanding the applied working loads. In addition, cutting system tests revealed that a 24-tooth blade achieved an efficiency of 26.9%, while a 40-tooth blade reached only 22.3%, indicating that the 24-tooth configuration provides better performance.
