Dini Rizqi Dwi Kunti Siregar, S.Si., M.Si., is a Senior Lecturer in the Department of Physics, Faculty of Mathematics and Natural Sciences (FMIPA), Universitas Syiah Kuala (USK), with research interests in material physics and instrumentation physics. She earned both her Bachelor’s and Master’s degrees in Physics from Universitas Sumatera Utara (USU), Indonesia, completing her M.Si. in 2021. Her research and development work focuses on superconducting materials, including the development of MgB₂ intermetallic alloy–based multifilament wire as a high magnetic field generator for medical brain tumor scanning devices, the superconductivity of carbon-doped Bi-2223 prepared via sol–gel and repeated sintering methods, and the effect of Mg addition on the heat treatment of MgB₂ superconductors, supported by funding from the National Research and Innovation Agency (BRIN) and the Indonesian Institute of Sciences. She is actively involved in national collaborations on superconductor technology for MRI efficiency and sustainable energy applications, and has published on enhancing superconducting properties in BPSCCO and Bi, Pb-2223 systems, as well as on multi-objective optimization methods for decision support systems. Dini is a member of the Physical Society of Indonesia (PSI) and teaches in the Bachelor’s program in Physics at USK.
