Bamboo Reinforcement Concrete Beam as Innovation for Low-cost Earthquake Resistant House

The aim of study is to know about shape, specification, strength, and reduction bamboo reinforced concrete cost construction percentage against reinforced concrete. This study was conducted with a comparative quantitative method. The comparison examined includes cost reduction that occur when using bamboo. Study was using one of bamboo species called Bambusa Vulgaris which has great growth potential in Tidore City, especially Rum District. Bambusa Vulgaris is a strong and recommended bamboo for application as a construction material. Based on the analysis results, bamboo reinforced concrete has enough strength to replace the type of steel-reinforced concrete construction on sloof beam and ring beam. The use of bamboo as reinforced concrete for simple houses projects could save projects cost up to 10.4 million rupiahs. It reflects that Rum Village and Tidore City has tremendous bamboo potential to be used as a structural material. That fact expected that the results of this study can be empirically tested in the laboratory to determine mechanical properties of bamboo reinforced beams originating from Tidore City. For the long term, it is hoped that the local government can move together with the society of the Tidore City to cultivate bamboo seriously and sustainably.
