This paper presents the results on dielectric properties of pulverized material based on agricultural waste namely oil palm frond and pineapple leaf fiber for microwave absorber application in the X-band frequency range. The investigation is started by identifying the pulverized materials permittivities and loss tangents using coaxial probe technique, followed by density measurement comprising the determination of bulk and solid densities. Then, by using dielectric mixture model, the solid particle dielectric properties were determined. It is observed that the air properties give quite an effect on the permittivity and loss tangent of the pulverized materials. It is also found that the lower the material density the higher material dielectric constant will be. Furthermore, the results show that, both oil palm frond and pineapple leaf fiber are potential to be X-band absorber with average dielectric constant of 4.40 and 3.38 respectively. The loss tangents for both materials were observed to be more than 0.1 which mark them as lossy materials.

To determine the the fiber fineness in different parts of the old and young leaves. the pineapple leaf fiber of smooth cayenne was used as raw material, The results showed that, the length of fiber extracted from the old leaves of smooth cayenne pineapple ranged from 80 cm to 100 cm, and the average fiber fineness of the the tip and root were 14.40 dtex and 18.53 dtex, respectively. While the length of fiber extracted from the young leaves of smooth cayenne pineapple ranged from 50 cm to 70 cm, and the average fiber fineness of the the tip and root were 13.27 dtex and 14.77 dtex, respectively. Variance analysis reveals that the fiber fineness of root and tip in the old pineapple leaf showed significant difference (P<0.05) in smooth cayenne pineapple.
