Priyo Prasetyo, a Physics student at UIN Sunan Kalijaga, the final months of 2024 were unlike any other. Through the Student Mobility Program 2024, Priyo had the opportunity to take part in an international internship at the Faculty of Science, Prince of Songkla University (PSU) in Thailand. From October 2024 to January 2025, he found himself not only immersed in advanced scientific research—but also in a new culture, language, and way of life.

Research with Real-World Impact

At PSU, Priyo joined the Material Physics Laboratory, working under the supervision of Assoc. Prof. Dr. Chatchai Putson. His project focused on studying the dielectric properties and energy storage potential of PVDF-HFP/PMMA/GNP thin-film nanocomposites—materials with the potential to revolutionize batteries and supercapacitors.

What made the work even more meaningful was its purpose: helping improve energy efficiency and durability in electronic storage devices, with the broader goal of reducing electronic waste. Day after day, Priyo spent nearly nine hours in the lab, conducting experiments, analyzing results, and refining his understanding of materials science.

“It wasn’t just about doing the work—it was about learning how structured, goal-oriented research is done in an international setting,” Priyo shared. “I gained new insight into how science can have a lasting impact on real-world problems.”

A Lesson in Confidence and Communication

Beyond the lab bench, Priyo also challenged himself in other ways. Working in a foreign country required him to communicate in English, collaborate across cultural boundaries, and adapt quickly to new routines. Conversations with his supervisor and labmates helped him grow more confident in speaking and presenting in English—a skill he knows will be essential for his future academic and professional goals.

He reflected,

“It’s easy to feel overwhelmed or even lazy sometimes. But when you take responsibility for your growth, even small steps make a big difference. If you prepare yourself, you’ll be ready when an opportunity comes.”

Discovering Thailand: More Than Just Research

Outside of the lab, Priyo made the most of his time in Thailand. He often visited the campus library, built friendships with local students, and participated in cultural events organized by PSU’s International Relations Office.

One of the most memorable moments was joining the Loy Krathong Festival, a beautiful Thai tradition where people float small offerings on water to show gratitude and let go of negativity. The event included traditional costumes, music, dance, and even a runway competition—something he never expected to witness during a physics internship.

Priyo’s story is proof that learning doesn’t only happen in classrooms or labs. It happens when we step outside our comfort zones, embrace new cultures, and challenge ourselves to grow. His experience in Thailand is more than an academic milestone—it’s a life-changing chapter that will continue to shape his journey as a scientist and global citizen.
