    Tissue engineering, especially in bone scaffolds, significantly demands to act as the replacement for the defection of bone. Cross linker in the fabrication of scaffold plays a major role to optimize the connection between the pores. In this study, four different scaffolds of the concentration of crosslinker were fabricated using Monosodium Glutamate (MSG). The fixed ratio of HA: starch: 40: 60, was used in the fabrication of the scaffold. The concentration of the MSG were varied into 0%, 10%, 20% and 30%. Solvent - casting and salt leaching was used as scaffold fabrication technique. The scaffold's mechanical and the morphological properties were characterized by mechanical testing and water adsorption test. Scaffold with 10% concentration of MSG as a crosslinking agent shows the highest mechanical properties and the lowest in the water adsorption test, therefore, further study should be made to investigate the biochemistry reaction which happened at this percentage which shows the best crosslinking affect among all.

    Dielectric properties of rambutan wood (Nephelium Lappaceum) were investigated in three anisotropic directions, namely miters-cut, cross-cut, and rib-cut. Dielectric constants and dielectric loss factors were measured at ambient temperatures by using an impedance analyzer. The dielectric constant decreased as frequency increased from 4 to 1 MHz. Among the wood specimens, the rib-cut direction has the lowest dielectric constant, while the cross-cut direction has the highest value. A dielectric dispersion occurred within frequencies 100 Hz to 10 kHz, which corresponding to a relaxation peak as observed on dielectric loss factor spectra. The relaxation peak value of the dielectric loss factors shifted towards higher frequencies in the sequence of rib-cut, miters-cut, and cross-cut specimen. Above 500 Hz, the cross-cut specimen has the highest value conductivity than others. Generally, these variations were subjected to the anatomical structure in the wood, such as parenchyma, ray cell, vessel cell, and fiber cell.
