The Department of Mathematics UGM once again held a Statistical Computing Colloquium which was held virtually on September 7, 2021. The colloquium which was initiated by the Head of Statistical Computation Laboratory, Prof. Dr.rer.nat. Dedi Rosadi, S.Si., M.Sc., took the theme “Statistical Approaches for Data Science” and invited two speakers who have experience in the fields of statistics and data science, namely Dr. RB Fajriya Hakim, S.Si., M.Sc. from the Statistics Study Program at Universitas Islam Indonesia and Dr. Fatia Fatimah, S.Si., M.Pd. from the Mathematics Study Program at Universitas Terbuka Padang.

The colloquium started at 09.01 WIB and was officially opened by the Secretary of the UGM Mathematics Department, Dr. Nanang Susyanto, S.Si., M.Sc.. The event was then continued by presentations from the two speakers. The first session was given by Dr. RB Fajriya Hakim, S.Si., M.Sc. with title “Towards the development of soft social set analysis approach on social media”. In his presentation, he explained various types of data that exist in the world of social media and how important soft-sets are in analyzing and making decisions from the data in the world of social media. Continuing the discussion regarding soft-sets, the second session was then filled with presentation from Dr. Fatia Fatimah, S.Si., M.Pd. who talked about “N-Soft Sets: Theory, Application, and Research Potential”. The N-Soft set theory is a new theory she developed during her doctoral study at UGM and it has been used as a basis for research by many researchers around the world. The applications and research potentials of this theory are quite diverse, starting from the fields of topology, game theory, decision making, data science, social science, medical diagnosis, forecasting, and others.

In general, the event which was held via zoom went smoothly and was attended by more than 200 participants. Hopefully, from this colloquium, participants will not only gain knowledge, but also can get motivated to participate in developing/collaborating/applying existing/new theories to other fields.
