Abstract

Angklung Gubrag is an ancient angklung that originated from Cipining Village, Bogor. The community of Cipining beliefs that Gigantochloa pseudoarundinacea is preferred as angklung's raw material compared to Gigantochloa atroviolacea. This study aimed to compare the fiber characteristic and sound intensity of G. atroviolacea and G. pseudoarundinacea culms as raw material of Angklung Gubrag. The study was conducted between February to December 2016. Methods used to compare the fiber characteristic of bamboo culms was maceration, while sound intensity was measured by sound level meter. Maceration samples were observed under microscope at Bio Imaging Laboratory, Department of Biology, Universitas Indonesia. The results showed that sound tube of Angklung Gubrag G. atroviolacea have lower sound intensity than Angklung Gubrag G. pseudoarundinacea. Fibre length of G. atroviolacea is longer that G. pseudoarundinacea. We also found that the fiber diameter, lumen diameter, and fiber wall thickness of G. pseudoarundinacea sound tube at third note was higher than G. atroviolacea sound tube at the same note. These showed similar results with the perception of Cipining community in choosing G. pseudoarundinacea as a raw material of Angklung Gubrag.
