Ilham Daeng also discussed the concept of modernity. According to Ilham Daeng, Modernity is a historical concept that becomes a reading tool in breaking down complexity in the existing time span. Modernity can also be said as an attempt to explain more variously the reality of urban history in Indonesia. After the first session was finished, then the second session was started at 3:00 to 17:00 in the same time by Verena H. Meyer who discussed the Two Kauman Sons: Collective Memory in Muhammadiyah and NU.
