“Three Unsoed teams successfully presented their work to an international jury at the final stage. “We have to compete with 15 other countries, including Malaysia, the Philippines, Thailand, Sri Lanka, South Korea, Poland, Saudi Arabia, and Vietnam,” he told the media.
He added, “The participation of Unsoed students in this event proves that Unsoed students can compete on an international scale and can motivate other students from various disciplines to continue to innovate and participate.” (*/est)
