Research to utilize natural polymers continues to be driven primarily by utilization as an environmental friendly energy-generating and storage material. The high porosity makes cellulose acetate (CA) a good candidate as a dielectric material as the basis of the supercapacitor device. Various dopants and compositions have been widely used, but the nano size morphological differences of the same material are rarely reported. Two types of ZnO are prepared, i.e., nanoparticles and nanorods deposited with CA and deposited on ITO glass substrate. The CA-ZnO / ITO composite film was fabricated through spin coating technique. This study focused on ZnO morphological difference on the microstructure and the dielectricity of CA-ZnO /ITO composite films. The morphology of nanoparticles and nanorods of ZnO were analyzed more detail with respect to its microstructure and dielectric properties. It is revealed that the change of ZnO morphology from nanoparticles to nanorod increase the capacitance and dielectric constant significantly from the order of the nano to the micro and decrease the dielectric loss. The dielectric constant of CA-ZnONP/ITO and CA-ZnONR/ITO are respectively of 2569 and 97159 at 100 Hz. The capacitance and dielectric loss of CA-ZnONP/ITO and CA-ZnONR/ITO reach to 69.809 nF; 678 and 2,15765 ÂµF; 13,23 respectively.Â

This study aimed to explore the effectiveness of modeling instruction based on a system for improving student’s understanding of energy concepts on high school students. This Research was a mixed-method design with an embedded experimental model. The subject of this study was the 62 students of 11th grade, at Senior High School in Nganjuk, Indonesia. Modeling instruction based on system learning could significantly improve students' understanding of concepts better than conventional learning. Based on the calculation of the effectiveness of learning using N-gain obtained for 0.33 (medium or low medium category) for the treatment class and 0.18 (low category) for the control class. It concluded that improved students' conceptual understanding of the treatment class was better than the control class. This research also was identified student’s difficulties especially in differentiating forces and work. Students propensity to use p-prime in solving problems rather than using energy theorems.
