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 one of the polytheists" (QS Yusuf: 108) Da'wah is not something that can be carried alone but must be carried together and organized. The long journey of da'wah indicates that there must be a foundation of common perception to bring the da'wah according to the stated goals. Along with the change in the management of the MOSAIC FEB UNAIR Student Activities Unit, it is necessary to hold an introductory activity for all new internal management of the organization to strengthen the relationship between members. It is hoped that when this activity has been carried out, all levels involved in the management of the organization will 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 faculty student activity unit in the field of Islamic spirituality held upgrading activities for MOSAIC itself internally. Upgrading was carried out on Saturday and Sunday, 29 February – 1 March 2020 at Lawang Adventure Camp Malang. This activity was carried out to equalize perceptions and strengthen MOSAIC's internal brotherhood in carrying out one year of management. The equalization of perception and unity of the Ukhuwah is necessary because da'wah cannot work alone, just as organized crime is more frightening than unorganized goodness, so da'wah needs to be organized. Therefore, MOSAIC FEB UNAIR held Upgrading activities through the Muslim Resources Empowerment Division (PSDM). Through this activity, it is hoped that all administrators for the 2020 period will be able to apply the organization's operating standards.
