Abstract

The use of environmentally friendly materials is getting serious attention from countries in the world today. One of them is the use of natural fibers, namely coconut fiber. This study was conducted to determine the physical and mechanical properties of single coconut fiber with alkaline NaOH treatment at the time of fiber immersion for 2 hours and with a concentration of 2.5%, 5% and 7.5% NaOH solution. In this study the method used for the process fiber testing was the tensile strength test of a single fiber and SEM to determine the shape of the surface morphology of the fiber without treatment and with the alkali treatment of NaOH. The selected coconut fiber is immersed in an alkaline solution for 2 hours with a solution concentration of 2.5%, 5% and 7.5% NaOH. Fiber drying process by drying in open space for 7 days. Fiber with 5% alkali treatment has the most tensile stress optimalis 136.091 Mpa. So the treatment of NaOH increases the tensile stress on the fiber. In the test Scaning Electron Microscope (SEM) results of fibers with the treatment of 7.5% NaOH concentration optimally can clean lignin and hemicellulose attached to the fiber surface.
