Performance Evaluation of Indonesian Prefabricated Modular School Building

Indonesia, in the Pacific Ring of Fire and at the convergence of three tectonic plates, is vulnerable to natural disasters. Disasters cause property damage and disruptions. Therefore, accelerating post-disaster reconstruction is essential to speed recovery and normalize community life. The Indonesian government has developed modular prefabricated concrete technologies— Simple and Healthy Instant House (Rumah Instan Sederhana Sehat/RISHA), Excellent Home Instant Panel System (Rumah Unggul Sistem Panel Instan/RUSPIN), and Interlocking Frame Building Concrete Construction (Bangunan Rangka Interlok Konstruksi Beton/BRIKON)—to rebuild detached housing for disaster victims since 2015. RISHA is the most popular technology and has many certified applicators, so it has also been used to speed up public infrastructure reconstruction, including school reconstruction. This study will evaluate these three technologies, which have design limitations for school buildings, using assessment parameters developed for this research to achieve optimal results. To establish these assessment parameters, literature reviews, site observations, and structured interviews focused on design, production, and construction, weighting these parameters with the Analytical Hierarchy Process (AHP). Technique for Order Preference by Similarity to Ideal Solution Analysis (TOPSIS) was used to choose the best technology. For modular prefabricated schools, RUSPIN outperformed RISHA and BRIKON in design, production, and construction.
