### Effect of Location of Enset Bundle Fiber Physical Properties  
The distribution of physical properties of Enset fiber along fiber sections was investigated quantitatively. By analyzing the fiber sections throughout the length of the four segments, EV-I, EV-III, and EV-IV, it was noted that the mass distribution was 5.9 \(\pm\) 1.85, 5.5 \(\pm\) 1.7, 5.1 \(\pm\) 1.6, and 4.9 \(\pm\) 1.6 mg for each section, respectively, as presented in Table 1. The results indicated that the mass distribution along the fiber sections from the bottom to the top decreased by 18.3%, and the minimum value was noted at the top section, as presented in Figure 2, using Origin Software. In addition, the linear density also followed a similar trend, as presented in Table 1, and it was reduced by 18.75%. It was observed that the tenacity of the fibers significantly improved for the fibers with a medium linear density. This is not in agreement with [PERSON] et al. 's analysis, who reported that the tenacity of the fiber improved for the fibers with a low linear density [22]. The reduction in mass distribution and linear density along the fiber sections could be due to the variation in chemical composition, which occurs between the bundle fibers. [PERSON] et al. arrived at similar conclusion [23]. Additionally, the bundle diameters and cross-sections of EV-I, EV-II, EV-III, and EV-IV were evaluated. The analysis indicates that the fiber diameters were 158 \(\pm\) 31.3, 153 \(\pm\) 28 \(\upmu\)m, 140 \(\pm\) 30 \(\upmu\)m, and 134 \(\pm\) 30 \(\upmu\)m for the EV-I, EV-II, EV-III, and EV-IV samples, respectively, as demonstrated in Table 1 and Figure 3. This indicates that the diameter of Enset bundle fibers ranged from 134 to 158 \(\upmu\)m; this value is in agreement with the investigation by [PERSON] [24], and the standard deviation was found to be 30, which is a similar result to that of [PERSON] et al. [25]. The evidence of the Enset fiber family of _Musaceae_ showed that the shape of the Enset fiber is elliptical rather than circular [26]. The bundle diameter versus the fiber portion categorized for the four fiber sections is shown in Figure 3. The investigation of the fiber portions indicates that the fibers' diameters decreased from the bottom to the top by 15.19%. Similarly, the cross-sectional area of Enset fiber varied with fiber portion along the length. With the fiber portion increasing from the bottom to the top, Enset fiber showed a distinct decrease in its cross-sectional area. As a numeric expression, the cross-sectional area decreased from bottom to top from 0.0205 \(\pm\) 0.008 to 0.015 \(\pm\) 0.005991 mm\({}^{2}\), a decrease of 26.8%. This is the reason why the tensile strength of the fibers decreases as the fiber's transverse dimension increases; i.e.,there is a smaller ratio of the cell walls in the fiber cross-section. The variations in the Enset bundle fiber's cross-sectional area and diameter are correlated to its position within the Enset plant sheath. The tensile strength decreased as the transverse dimension of the fibers increased, namely in the Enset fibers. The lumen size of the tested fibers increased as the transverse dimension of fibers increased, and the mass of the material bearing the fiber diminished simultaneously. This difference may be due to the variation in fiber composition within the bundle fiber in the cross-sectional area. This information is supported by the authors of [5; 23; 27]. The non-uniform fiber cross-section adds to the high variability in the fiber's mechanical properties [28]. bundle fibers, the physical examination of the diameter, cross-sectional area, linear density, and mass distribution of the fiber revealed a broad variance over segments of the length and reduced as the length increased from bottom to top [29]. There may be a rare case during the decortication process where fibers may be fibrillated, and a maximum value is noted at the top portion of the Enset fiber.
