Good post, Roof of rumbia is a kind of roof something built from the foundation of Rumbia staple. In principle, the roof of rumbia is made up of "bones" or known as "bengkawan", which is made from the grout of the reeds or the small wood that is folded on the leaves of rumbia to form like a wing and stitched by using rattan or Bemban basic skin to bind it. In the present, because it is difficult to get the basic skin of the bemban, plastic or nylon straps are used for roofing. this interesting post, thanks @rebatesteem for sharing for all of us, this is very useful for us all
