Community service activities through formal host training were carried out by the Indonesian Language Student Association on July 23, 2023, at MA Raudhatul Islamiyah, Jalan Alam Roh, Paku Alam Village, RT. 01, Paku Alam Village, Sungai Tabuk District, Banjar Regency, South Kalimantan Province. This activity aims to provide training to all students on how to become a Host of Formal Events, in this case especially the Host of Formal Flag Ceremonies. Bearing in mind, the flag ceremony is a routine activity carried out by all schools in Indonesia starting from the elementary, junior high and high school levels. The flag ceremony is a sacred moment and to create this moment the presenter or commonly known as the MC becomes a very important and influential part because it has a role to guide how the activity goes.
