In his presentation, Prof. Hermawan emphasized the crucial role of polymer composite materials in addressing global challenges, particularly issues of global warming and energy efficiency. According to him, the transportation sector remains one of the largest contributors to carbon emissions.

“The heavier the vehicle, the more fuel it consumes, and consequently, the higher its emissions. This is where lightweight yet strong materials become the key to energy savings and reducing carbon emissions,” said Prof. Dr. Ir. Hermawan Judawisastra, M.Eng.

Polymer composites, especially Fiber-Reinforced Plastics (FRP), are among the solutions being developed as they possess strength and stiffness surpassing steel while being significantly lighter. In addition, these materials are corrosion-resistant, making them ideal for use in automobiles, aircraft, infrastructure, and modern construction.

He also explained the various types of composites that have been researched, ranging from layered composites, sandwich composites, and biocomposites, to studies on composite degradation and failure simulations.

“All of this research stems from a simple question: how can we create materials that are stronger, lighter, and more environmentally friendly,” he remarked.

His team even succeeded in developing a functional integrated structural battery—a material that not only serves as a structural component of a vehicle but also stores energy like a battery, thereby reducing overall vehicle weight and improving efficiency.

However, the development of biocomposites still faces several challenges. Prof. Hermawan noted that the mechanical properties of biocomposites tend to vary and they are prone to absorbing water, which makes them susceptible to environmental degradation.

“The issue of interface degradation between fibers and the matrix is extremely important. That is why we conduct extensive research focusing on fiber–matrix interface modification to enhance biocomposite performance,” he explained.

Beyond experimental research, simulation approaches and artificial intelligence (AI) are also being utilized to accelerate the prediction of composite material properties. This method allows for more efficient design evaluation compared to conventional simulations. According to Prof. Hermawan, this opens up significant opportunities to accelerate the adoption of composites on an industrial scale.

At the conclusion of his oration, Prof. Hermawan emphasized that the future development of composites cannot be pursued in isolation. “Synergy among academia, industry, and government is essential to establish a self-reliant and competitive ecosystem of research, innovation, and production,” he affirmed.

He also expressed his gratitude to his mentors, colleagues, students, and family for their continuous support throughout his academic journey leading to his appointment as a Professor. The scientific oration reaffirmed ITB’s commitment to advancing research driven by societal needs while making tangible contributions to sustainable development.
