August 15, 2025 – A team of UNNES Faculty of Engineering students consisting of Dimas Eka Firmansyah, Lorensius Bima Atmaja, and Fadil Nur Hidayat, along with their supervisor, Muhammad Irfan Nuryanta, S.T., M.Eng., won first place in the prestigious Creativity and Innovation Competition (Krenova) 2025, held by the Semarang City Regional Research and Innovation Agency on August 15, 2025.
This competition is a prestigious event that brings together innovators from various regions and categories to showcase creative and innovative ideas that benefit society.
In this year’s competition, the UNNES Mechanical Engineering Team presented an innovation entitled “Development and Implementation of 3D Printing Products Using Recycled PET-Based Filament with Natural Fiber Reinforcement.”
This innovation is a technology for processing PET (Polyethylene Terephthalate) plastic waste, such as used beverage bottles, into environmentally friendly 3D printing filament. This filament is reinforced with natural fibers, which have good mechanical strength and are environmentally friendly.
This technology is considered capable of providing a real solution to environmental problems, particularly reducing the accumulation of plastic waste, which is difficult to decompose in nature.
Furthermore, the use of natural fibers as reinforcement can reduce dependence on synthetic fibers, thereby supporting energy savings and reducing carbon emissions.
In the long term, the application of this innovation also has economic and social potential, as it opens new business opportunities in the circular economy and raises public awareness of the importance of technology-based recycling.
The use of natural fibers not only improves the mechanical properties of the filament but also saves production energy and reduces carbon emissions. This achievement led the UNNES Mechanical Engineering Team to win first place in the prestigious 2025 Creativity and Innovation Competition (Krenova) held by the Semarang City Regional Research and Innovation Agency.
Looking ahead, this research has broad prospects. In addition to contributing to the circular economy by opening business opportunities based on recycling technology, its application is also expected to raise public awareness of the importance of creative waste management.
The research team plans to develop a more efficient production process and explore partnerships with the manufacturing industry to expand the use of this environmentally friendly filament across various sectors.
The research also impacts SDG 9 (Industry, Innovation, and Infrastructure), providing an opportunity for UNNES engineering students to continue innovating and creating brilliant ideas to realize UNNES’s vision of becoming a Pioneering University of Educational Excellence.
