International mobility programs continue to contribute to the improvement of doctoral research quality and the development of global academic collaboration. Tika Elviana, a doctoral (Ph.D.) student in Science Education at Universitas Pendidikan Indonesia (UPI), participated in a Ph.D. Student Exchange Program at Prince of Songkla University, Phuket Campus, Thailand, from October 2025 to April 2026.

This program reflects UPI’s ongoing effort to strengthen international academic engagement and expand research networks. During her time in Thailand, Tika was hosted by the Faculty of Technology and Environment at Prince of Songkla University, where she conducted research under the supervision of Assoc. Prof. Thongchai Suteerasak.

The success of this program is closely related to consistent academic supervision and collaboration between institutions. At UPI, Tika’s doctoral research is supervised by Prof. Dr. Andi Suhandi, M.Si., whose guidance supports the continuity and development of her research throughout the exchange period.

During the program, Tika took part in various academic and research activities, contributing to studies in science education and environmental technology. Her research focuses on energy systems, particularly in analyzing energy flow and evaluating energy sufficiency in a solar-battery IoT-based weather station operating in tropical environments.

As part of the program, Tika delivered her final presentation organized by the Faculty of Technology and Environment. She presented her research entitled “Empirical Energy Flow Analysis and Energy Sufficiency Margin Evaluation of an Undersized Solar-Battery IoT Weather Station in a Tropical Environment,” which forms part of her doctoral dissertation.

Her research has shown strong academic contribution and has been accepted for publication in a Scopus Q2 indexed international journal. This achievement reflects both her research capability and the increasing global engagement of UPI’s doctoral students.

In addition to research activities, the program also provided opportunities to engage with international scholars, exchange ideas, and develop academic networks. These experiences help broaden academic perspectives and support future research collaboration.

Overall, this international exchange highlights the value of global mobility in doctoral education. It not only broadens academic perspectives but also supports research productivity and international collaboration in science education.
