Figure 1 shows the morphology of the untreated coconut fiber. It can be observed that the fiber surface is covered with protrusions which indicated by oval shape and also some small voids and long crack. It has been reported that the surface of the untreated coconut fiber was covered with a layer of substances; these may include pectin, lignin and other impurities. The surface was not smooth, spread with nodes and irregular stripes [3]. Figure 2 indicates EDS analysis that performed at a micro region of the fiber surface indicating the presence of carbon, oxygen (organic impurities) chlorine and potassium elements in the fiber (inorganic impurities).
