Dr. Mursal, S.Si., M.Si., is an Associate Professor in the Department of Physics, Faculty of Mathematics and Natural Sciences (FMIPA), Universitas Syiah Kuala (USK), with research interests in modern physics, semiconductors, electronic materials, and the structure and physical properties of materials. He earned his Bachelor’s degree in Physics from USK and both his Master’s and Doctoral degrees in Physics from Institut Teknologi Bandung (ITB). His recent research focuses on photocatalytic and renewable-energy materials, including Fe₃O₄–TiO₂ nanoparticles for the degradation of phenolic compounds and pesticide waste; Mg-doped TiO₂ photoelectrodes and natural dyes for dye-sensitized solar cells (DSSC); and the development of wave learning media using MEMS technology and Tracker through an ISLE-based STEM approach. He has also worked on coconut-shell-based biocomposites using waste plastic as an adhesive and spent coffee ground biocomposites, in collaboration with industrial partners such as PT Solusi Bangun Andalas. His publications cover photocatalytic performance of Fe₃O₄–TiO₂ derived from natural iron sand, magnetization studies of Sabang iron sand, optical characterization of natural dyes for DSSC, organic nanoparticle-based biocomposite boards, and hydrogen desorption properties of MgH₂-based systems. A member of the Physical Society of Indonesia (PSI), Dr. Mursal teaches in both the Bachelor’s and Master’s programs in Physics at USK.
