Uwais Al Qarni Mosque (UAQ) is located on the northern outskirts of Makassar city, precisely on Jl. Manuruki Batara Ugi Housing, Sudiang Raya Village, Biringkanaya District, Makassar. One of the stages that will be realized in the construction of this mosque is the procurement, installation and installation of a sound system. In connection with this problem, PKM activities are to help partners, namely the Uwais Mosque Management. The form of this PKM Cooperation is the procurement, installation and installation of a loudspeaker system (sound system). This activity began with a visit to the location on June 26, 2022, the purpose of which was to review the installation of the sound system and discuss with the mosque management. Furthermore, the purchase of sound system equipment and supporting equipment, then installation and installation is carried out before carrying out the Eid al-Adha prayer 10 Dzulhijjah 1443H. In accordance with the target, the installation and testing of the sound system has been completed and is used during the Eid al-Adha prayer until now. The sound of the Azan can be heard by the surrounding community every time for the five daily prayers and other announcements. The hope of the local community is that there are other PKM activities that can be carried out at the mosque.
