ABSTRACT
Assembling bamboo as a building construction material becomes challenge to using a sustainable technology. One technique for assembling bamboo is to unite bamboo using ropes or items with long threads, made from various materials, such as coconut fiber, artificial fibers, plastic, etc. some of which are spun. The principle is to use the frictional force between the surface of material that is tied to material of the strap. This study aims to show the behavior of use various materials that are often used in tying bamboo for building construction and recommend the type of fastening connection. The research was conducted by observation and experimental testing to make a bonding model on bamboo and then described it descriptive. The problem that occurs is that over time the construction of buildings from bamboo using tying techniques will experience changes in shape due to loosening of the bonds at the joints which disrupt the stability of the building construction. The cause is the occurrence of expansion or shrinkage of the bamboo stem and its binding tools.
