The priority of maintaining the reliability of sustainable construction at the Ampel Mosque Surabaya

The Ampel Mosque was founded in 1421 by Raden Mohammad
Ali Rahmatullah (Sunan Ampel). The Ampel Mosque is located in Ampel
Village, Semampir subdistrict, Surabaya City, East Java, Indonesia. The
Ampel Mosque was built with a Javanese architectural style and nuances of
Arabian Islam. The mosque is influenced by the acculturation of local
culture (local wisdom) and Hindu-Buddhism as seen in the architecture of
the building. This study aims to determine the priority of maintaining the
reliability of sustainable construction at the Ampel Mosque. The method
used was Importance Performance Analysis (IPA) and Quality Function
Deployment (QFD). The data obtained from the research concluded that
the highest demand requirements are the convenience and accessibility
levels, in terms of structural components’ maintainability. The highest
priority variable to be increased is non-hazardous building materials. The
highest target is the guarantee of the design and configuration of nonhazardous construction systems. These variables can be considered in the
repair and improvement of the maintenance of the Ampel Mosque by the
mosque management institution.
