Dr. Rajibussalim, S.Si., M.Sc., M.InfoTech, is a faculty member in the Department of Physics, Faculty of Mathematics and Natural Sciences (FMIPA), Universitas Syiah Kuala (USK), with research interests in computational physics, web design and databases, computer networks and systems, disaster and environmental applications, STEM education, and integrated science. He earned his Bachelor’s degree in Physics from USK, a Master of Information Technology from Flinders University, Australia, a Master of Science in Computing from the University of Sydney, and a Ph.D. in Sciences and STEM Education from Queensland University of Technology, Australia. He heads the Theoretical and Computational Physics Laboratory and the Physics Theories and Computation Research Interest Group, and serves nationally as an LPDP scholarship interviewer and assessor for the National Accreditation Board (BAN-PDM). His recent projects include STEM-based learning media for thermodynamics and global warming, the integration of ISLE in science instruction to enhance STEM teaching (in collaboration with Rutgers University through the PEER-USAID program), and studies on industry-based learning for STEM students. His publications cover molten salt breeder reactor core simulations, disaster-mitigation STEM modules, and IoT- and LoRa-based mini weather stations and electronic learning platforms. Dr. Rajibussalim is a member of the Physical Society of Indonesia (PSI), is active in national education and scholarship committees, and teaches in both the Bachelor’s and Master’s programs in Physics at USK.
