Proposed Bamboo School Buildings for Elementary Schools in Indonesia

Indonesia has serious problems of educational infrastructure where thousands school facilities are in poor condition. In 2011 182.500 classrooms were moderately damaged and 110.598 ones were in severe condition. In order to find a cheap, quick and sustainable solution for the problem above, a design of bamboo building for school is proposed. In this research, internal forces were analyzed by computer software, Structural Analysis Program 2000 v11. Bamboo used for elements of structure is wulung bamboo (Gigantochloa atroviolacea widjaja) and the analysis based on SNI-5 2002 (Standard for Timber Construction Design Procedures in Indonesia). Construction cost was estimated based on SNI (Indonesian National Standard). For bamboo elements which the unit price calculation guidance is not available yet, data survey from the bamboo contractors were used. From the design, most of the elements require bamboo with external diameter of 10 cm. The construction cost estimation range from IDR742,398.02/m2 to IDR795,145.22/m2 (1 USD = 10,000 IDR) in Yogyakarta per May 2013, depend on the design type. The proposed design save construction cost up to 50% compared to conventional building (Rp 1,500,000/m2) in Yogyakarta.
