Abstract

This research was conducted to determine the physical and mechanical properties of a single bamboo fiber with alkali treatment for two hours with a concentration of 0%, 2,5%, 5%, and 7,5%. In this research the material used was bamboo apus (Gigantochloa apus). The method used for the testing process is a tensile test with ASTM D3379-75 standart and Scanning Electron Microscope (SEM) test. Based on the research that has been done, the author has obtained good and sufficient test results to obtain optimal value from a single bamboo fiber. In the tensile test the highest tensile strength was found at 5% NaOH concentration tensile stress 714.975 Mpa, strain 2.67% and elastic modulus 268,183 Mpa while the lowest strength on bamboo fiber without alkali treatment, with tensile stress 366,057 Mpa, 2% strain and elastic modulus 183,028 Mpa. In the Scanning Electron Microscope (SEM) test there was a significant change in the shape of the surface of bamboo fiber without alkali treatment and alkali treatment. The shape of the surface of bamboo fiber without alkali treatment is still covered by layers such as lignin and hemicellilose, whereas in the alkali treatment the layers of lignin and hihelellulose experience peeling, the more the percentage of alkaline NaOH the cleaner the bamboo fiber layer.
