The emergence of the idea of the National Mathematics and Applied Seminar, abbreviated as SiManTap, was initiated by the Regional Board of IndoMS on 2010 by Bpk. Syahril Efendi, who currently serves as the Governor of the IndoMS in Aceh-North Sumatra region, where the first SiManTap organizer is the Department Mathematics FMIPA USU. Since 2011, this activity is an annual IndoMS agenda. This SiManTap activity aims to make the forum for researchers, lecturers, teachers and students to exchange ideas, experiences, research and application in the field of mathematics and mathematics education. In its implementation, SiManTap is held alternately in the Provinces of Aceh and North Sumatra. The 13th SiManTap in 2023 will be held on November 28-29, 2023 at Potensi Utama University
