Abstract

Indonesia is one of the countries with abundant availability of palm fiber composite, yet its application in advanced material technology remains limited. On the other hand, most motorcycle helmets available in the market are made from ABS plastic, which has limitations in impact energy absorption and may increase the risk of head injuries during accidents. This study aims to develop helmet composites based on palm fiber and epoxy resin by varying the fiber volume fractions (15%, 25%, and 35%) and alkali soaking durations (75, 150, 225, and 300 minutes). The impact strength test results showed that the combination of 35% fiber volume and 225-minute alkali soaking produced the highest specific impact energy (SIP) of 0.142 J/mm². As a comparison, SNI-compliant helmets made from ABS plastic only reached an EPS value of 0.00972 J/mm², indicating that palm fiber-based composite helmets could improve impact energy absorption efficiency by more than 14 times. The results conclude that increasing the fiber volume fraction and optimizing the alkali treatment duration significantly enhances the impact resistance, making ijuk-based composite helmets a promising alternative for safer and more eco-friendly protective gear.

Review

This study presents a compelling investigation into the potential of palm fiber (ijuk) reinforced epoxy resin composites for advanced helmet applications, addressing both material innovation and safety concerns. The research is highly relevant given Indonesia's abundant natural resources and the pressing need for safer motorcycle helmets. By systematically varying fiber volume fractions and alkali treatment durations, the authors aim to develop an eco-friendly alternative to conventional ABS plastic helmets, which are noted for their limitations in impact energy absorption. The core objective of enhancing impact resistance for improved head protection is clearly articulated, setting a strong foundation for the experimental design. The findings demonstrate significant promise for ijuk-based composites. Specifically, the combination of 35% fiber volume and a 225-minute alkali soaking duration yielded an impressive specific impact energy (SIP) of 0.142 J/mm². This result is particularly noteworthy when compared to SNI-compliant ABS plastic helmets, which registered a significantly lower EPS value of 0.00972 J/mm². The reported improvement of over 14 times in impact energy absorption efficiency highlights the exceptional potential of these bio-composites to drastically enhance rider safety. This innovative approach to material selection and processing offers a viable pathway toward more sustainable and high-performing protective gear. While the abstract provides strong evidence of superior impact strength, a comprehensive journal article would ideally delve deeper into other critical aspects of helmet performance. Future work should consider evaluating additional mechanical properties crucial for helmets, such as penetration resistance, crush strength, and dynamic shock absorption characteristics under various environmental conditions. Furthermore, aspects like the long-term durability, weight optimization, manufacturing scalability, and cost-effectiveness of these composites would be essential for practical implementation. Nonetheless, this study lays robust groundwork, concluding that optimizing fiber volume and alkali treatment profoundly enhances impact resistance, positioning ijuk-based composite helmets as a highly promising and environmentally conscious alternative for the protective gear market.
