OSB (Oriented Strand Board Green Building): Utilization of OSB Betung Bamboo (Dendrocalamus asper (Schult. F.) Backer ex Heyne) by Testing Physical and Mechanical Properties to Optimize Eco-Friendly Construction in Indonesia

Abstract

Abstract The National Institute of Building Science (US) states that building materials that come from nature can produce greenhouse gas emissions such as 35% of carbon dioxide, 49% of sulfur dioxide, and 25% of nitrogen oxides. These gasses cause the construction will be unfriendly for the environment, so we need a green construction materials. Bamboo is one of the alternative green constructions because the easiest way to build, elastic and resistant to earthquake, as well as easily repaired in case of damage. OGB (Oriented Strand Board Green Building) is a solution in the use of betung bamboo for green building construction by conducting several tests. This test aims to determine the physical and mechanical properties of betung bamboo by using phenol-formaldehyde (PF) with adhesive contents of 6%, 7%, and 8%. The results showed that the differences in adhesive content of 6%, 7%, and 8% significantly affect the value of density, moisture content, water absorption, thickness, and internal bonding. OGB can be used as a solution for improving eco-friendly building construction in Indonesia.
