It indicates that the quality of the existing concrete of the Al-Hidayah Mosque does not meet the requirements of SNI 2847-2019 Article 19.2 concerning the minimum allowable normal concrete quality, then the design is carried out according to space requirements and a structural analysis is carried out on the planned design. The planned design is based on the existing space and land requirements which are 15 m x 14 m with a height of 3.5 m per floor and structural analysis is declared safe.
