Intan Mulia Sari, 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 teaching responsibilities in the Bachelor’s program in Physics and a research interest in medical physics and STEM-based physics education. She earned both her Bachelor’s and Master’s degrees in Physics from USK, completing her M.Si. in 2021. Her master’s research focused on developing an Investigative Science Learning Environment (ISLE)-based mechanics learning module using MEMS technology and Tracker applications, funded by DRPM-Ristekdikti. Over the past five years, she has been actively involved in research and community service related to STEMC learning modules, including preparation, training, and curriculum support activities in collaboration with the Aceh Education Office and CSR-PLN Aceh Region. Her recent publications cover topics such as spatial assessment of soil erosion using the RUSLE model for coastal ecosystem sustainability, the effectiveness of block programming and educational robots in enhancing computational thinking through STEMC, smartphone microscope-based learning outcome measurement, integration of STEMC in Indonesia, and MEMS- and IoT-based ISLE STEM physics learning media. Intan is a member of the Physical Society of Indonesia (PSI).
