Recycled Materials in the Development of Shin Guards for Sepak Raga Tuju: A Green Innovation Supporting the Sustainable Development Agenda (SDG 9 and SDG 12)

Abstract

Awareness of sustainability in sports product design is increasing, especially through the use of recycled materials to reduce environmental impact. This study aimed to design and develop an eco-friendly foot protection prototype for the traditional sport of Sepak Raga Tuju, by integrating green innovation in the local context. The development process involved the use of readily available waste materials such as insulation pipes and polyethylene foam, which were selected for their lightweight and environmentally friendly properties. The study methods included product design and fabrication, material composition analysis using Fourier Transform Infrared Spectroscopy (FTIR), and evaluation of mechanical properties through ASTM D638 Tensile Testing. In addition, user acceptance evaluation was also conducted through the distribution of questionnaires to players and coaches. The FTIR test results confirmed the presence of the characteristic chemical structure of polyethylene, while the mechanical test showed a maximum elongation of 80.2% and a breaking stress of 0.219 MPa, which reflects the basic shock absorption capacity. Overall, the prototype demonstrated adequate basic protection functions while contributing to the reduction of material waste. This study supports the Sustainable Development Goals (SDG 9 and SDG 12) and offers an innovative approach that combines aspects of sports safety, environmental sustainability and the economic value of recycling in the development of traditional sports equipment.
