The dissemination activity which was carried out on Friday 17 November 2017 with the title Differential Equations and Their Applications was delivered by Nikenasih Binatari, M.Si. and Kusprihantoso K, M.Si. who are lecturers at the Mathematics Education Department, FMIPA UNY. The participants were 80 Mathematics study program students. This event went smoothly where the resource person delivered material and continued with a question and answer discussion about the Partial Differential Equations application. This activity is a continuation of the Partial Differential Equations workshop in Palembang which was attended by three lecturers, namely Nikenasih, Kusprihantoso, and Fitriana Yuli S. Furthermore, the material received from the workshop was delivered to students to increase their knowledge about Partial Differential Equations. Apart from that, the implementation of this activity is expected to provide preparation and material for students' final assignments.
