Strengthening the Brotherhood, Straightening the Path to Realizing Da'wah "Say "this is my (religious) path, I and the people who follow me invite Allah (preaching) with real arguments. Glory be to Allah, and I am not of the polytheists” (QS Yusuf: 108) Da’wah is not something that can be borne alone but must be borne together and organized. The long journey of da’wah indicates that there must be a foundation of shared perception to bring da’wah to run according to the goals that have been set. Along with the change in the management of the MOSAIC FEB UNAIR Student Activity Unit, it is necessary to hold an introductory activity to all new management that is internal to the organization to strengthen the relationship between members. It is hoped that when this activity has been carried out, all ranks who are included in the management of the organization can understand, comprehend and be able to carry out the duties and obligations that have been mandated to them during the management period without any obstacles. MOSIAC (Moslem Students Association of Economics and Business faculty) as a student activity unit of the faculty in the field of Islamic spirituality held an upgrading activity for internal MOSAIC itself. The upgrading was held on Saturday and Sunday, February 29 – March 1, 2020 at Lawang Adventure Camp Malang. This activity was carried out to equalize perceptions and strengthen the internal brotherhood of MOSAIC in carrying out its first year of management. Aligning perceptions and solid brotherhood are necessary because da'wah cannot run alone, just as organized crime is more frightening than unorganized goodness, so da'wah needs to be organized. Therefore, MOSAIC FEB UNAIR held an Upgrading activity through the Muslim Resource Empowerment Division (PSDM). Through this activity, it is hoped that all administrators for the 2020 period will be able to apply the organization's operational standards.
