This research aimed to develop interactive multimedia based on scientific inquiry to improve student mathematics problem-solving as a provision for the era of Society 5.0. The research method used is the Agile Method, a software development method. One hundred twenty students of Madrasah Ibtidaiyah Teacher Education Department, Universitas Muhammadiyah Sidoarjo were involved in this research. The results of the development of Interactive Mobile Mathematics Inquiry (IMMI) were valid and proven to improve student problemsolving abilities. In particular, this increase is significant in planning and implementing student plans for a problem. The significance is due to the training in the inquiry aspects during the use of IMMI. This educational technology research implies that IMMI can be a preliminary study and a pioneer for lecturers, experts, and practitioners. Thus, IMMI can be developed further to improve students' mathematical problem-solving skills in higher education as preparation for media availability following the values of technological advances in the Society 5.0 era.
