Abstract

Misconception is a condition where students' concept understanding is different from the opinion of experts. Many misconceptions occur in physics learning, one of which is motion material. The purpose of this study is to mapping research on misconceptions on the concept of motion so that it can be a further reference for research on misconceptions in motion materials. The database was obtained through the Scopus web for 20 periods (2005 to 2024). The data search resulted in 353 relevant research articles. The results of data analysis show that the development of research on misconceptions in motion material shows an increase in the number of publications. The most popular development of research on misconceptions in motion material occurred in 2020. The country that produces the most articles about research on misconceptions in motion material comes from the United States. Most of the published articles are in journals indexed in the Scopus database. The author affiliation with the most publications came from Padang State University. This study successfully used bibliometric analysis to describe the development of research on misconceptions in motion materials.

Abstract

This study aims to synthesize ferrite (Fe₂O₃) nanoparticles using the green synthesis method based on cermai leaves extract (Phyllanthus acidus) and analyze its functional group, morphology, element composition, and electrical properties. The synthesis process is carried out with calcination temperature variations of 500 °C, 600 °C, and 700 °C. FTIR characterization shows the formation of Fe–O bonds as well as reduced organic residues as calcination temperatures increase. SEM results show an almost spherical particle morphology with a tendency to increase grain size and agglomeration at higher temperatures. EDX analysis confirmed that the material is composed of elements Fe and O without significant impurities, with compositions closest to stoichiometry Fe₂O₃ obtained at intermediate calcination temperatures. Electrical properties tests show that an increase in calcination temperature leads to an increase in the dielectric constant and a decrease in resistivity, which is related to grain growth and an increase in the regularity of the crystal structure. The results of this study show that cermai leaf extract has the potential to be a green synthesis agent in producing Fe₂O₃ nanoparticles with good electrical properties and environmentally friendly.
