Abstract

Teacher competency standards serve as benchmarks that can be utilised to assess the attributes deemed essential for professional competence in educators. Educators play a crucial and strategic role in the pursuit of national development objectives, particularly within the realm of education. However, the objective of education appears to be a reduction in competency standards at the conclusion of each academic year for specific subjects, particularly in the realm of science and Basic Physics. Consequently, this initiative seeks to inspire educators and students in secondary education to enhance their understanding of the educational process by engaging in the study of science, specifically Basic Physics, utilising appropriate tools and resources. The suggested mode of engagement involves the processes of instruction and education within secondary educational institutions across the Meranti Islands Regency, encompassing SMA, MAN, MTs, and SMP levels. This activity further offers insights into experiments and demonstration tools for educators in the realm of science and Basic Physics, facilitating a comprehension of concepts that range from simple to intricate natural phenomena through accessible demonstration media designed for practical application. In this manner, educators are anticipated to exhibit motivation and enthusiasm throughout the learning process, accompanied by a thorough and nuanced comprehension of the subject matter. To enhance teacher competency standards significantly, ensuring they become more qualified and professional.

Abstract

Crystal structure visualization and X-ray diffraction pattern simulation of various types of ZnO microstructures have been successfully carried out using the VESTA software program. The purpose of this study was to obtain the relationship between the shape of the structure, microstructure, and composition to changes in the pattern and peak diffraction. The software program produces information on the shape of the crystal structure and representative X-ray diffraction patterns for ZnO microstructures. This program requires input in the form of coordinates of each constituent atom, lattice parameters, and spatial symmetry. The output obtained is a graph of the diffraction pattern and crystal structure that provides an overview of the profile and type (phase) of the ZnO microstructure. The results showed that the peak position and intensity of the diffraction pattern were influenced by the arrangement of atoms in the unit cell. In variations in structure and microstructure, the position of the diffraction peak provides a different picture for each type of structure depending on the arrangement of atoms in the unit cell, where each crystal structure has a different position and spatial symmetry, resulting in different diffraction patterns. The nanorod structure has a monoclinic crystal system (a ≠ b ≠ c) with a space group of C 2 / c and lattice parameters a = 15.4170 Å, b = 25.3560 Å, and c = 14.3840 Å. The nanowire structure has a triclinic crystal system (a ≠ b ≠ c) with lattice parameters a = 12.0380 Å, b = 2.4910 Å, c = 16.8890 Å and a space group of P-1 and is the simplest form of symmetric lattice. The nanoflower structure has an orthorhombic crystal system (a ≠ b ≠ c) with lattice parameters a = 9.47310 Å, b = 13.52960 Å, c = 29.0220 Å and space group P b c a.
