Community Building is one of the agendas of the SEGA Department of BEM FEB UNAIR. Community Building activities are organized by the Department of Arts and Sports BEM FEB Unair. For Esports, the game genres that will be provided are Mobile Legend and PlayerUnknown's Battlegrounds Mobile. In its implementation, a fun match activity will be held which will be attended by students from each department at FEB who are interested in online games which will be held 3 (three) times in 1 (one) period. From this Community Building activity, an Esports team will also be selected to represent FEB to compete in every national and international competition. For Bands, a separate team will be formed which will later fill various events at FEB UNAIR.
