Abstract

Molecular dynamics method has been applied to model the phase transition of the aluminium (Al). We used the LAMMPS molecular dynamics code to simulate the physical process of the phase transition and observing the dynamics of atoms by using Jmol vizualitation code. From the simulation data we found that the phase transition where the melting point of the material is, can be observed at temperature T = 1059,75 K. In this view we may use the molecular dynamics method as an innovative model of physical learning model in senior high school level, as an alternative of dry lab. Keywords: Molecular dynamics method, Phase transition, Melting point, LAMMPS.

Abstract

For the design of fast nuclear reactors, usually it use the lead metal alloys for coolant materials. Researches about lead coolants, has been carried out experimentally. However, experimental studies in the nuclear material field, besides being expensive, usually also require high safety. In particular, research on the corrosive properties of liquid lead for structural materials requires serious treatment if carried out experimentally. In this case, the computational method is very helpful to overcome these obstacles. In our research we use the molecular dynamics simulation method to know the effect of temperatures and effect of liquid lead corrosion attack to iron material. We want to know that which one is most crucial that causing the damage of the materials: it is due to temperature or due to liquid lead attack. It has been observed from MSD curves of simulation results that the liquid lead can make iron material experiencing most damage if compared with temperature effect The interactions among atoms are described by the Lennard-Jonnes interaction potential. The simulations was run and supported using Moldy and Ovito software.Keywords: Corrosion of molten lead, fast nuclear reactor, molecular dynamics simulation, Moldy, MSD, Ovito.

Abstract

Changes in learning patterns that are taking place rapidly due to Covid-19 have made every educational institution able to quickly adapt, especially in the use of learning technology. Teacher readiness in optimizing the use of technology to support the learning process is a new problem that arises when the concept of digital learning begins to be echoed. The use of technology can help teachers visualize material (such as in science learning Physics) and assist teachers in conducting evaluation activities in a practical and efficient manner. The limitations of teachers, especially in several educational institutions in South Tangerang to utilize technology in learning, are the background of the importance of training activities carried out. The results obtained after implementation refer to the evaluation of tasks and practices observed during the training process, indicating that there was an increase in teacher skills in utilizing technology to support the learning process. The teachers who have attended the training have been able to integrate the use of virtual laboratory applications and evaluate student learning outcomes using the quizizz application. The training on the use of learning technology is one of the forms of support from the Physics Education Study Program of FKIP UT to assist and assist teachers in carrying out technology-based learning activities, especially in Physics Science learning during the Covid-19 pandemic.

AR provides an effective learning experience because it displays 3D images so that it is easily accepted by students and makes students interested in learning. This study aims to develop augmented reality media to increase students' understanding of the eye optical system material. The type of research to be carried out in Research and Development, with the chosen development model being ADDIE. Product evaluation is carried out based on test results and product implementation. The population of this research is students of the Physics Education Study Program, FKIP UT, who are enrolled in the 2021.2-semester lectures and tutors for the Physics Education Study Program, FKIP UT. The research sample was students of the UT FKIP Physics Education Study Program who attended several 18 people (from UPBJJ UT Bogor, Jakarta, and Serang and tuweb tutors for the optics course). The data collection method consisted of administering a questionnaire. To determine the level of understanding of student material on system material eye optics, test results given to students were analyzed descriptively. Questionnaire analysis from tutors and students regarding the need for AR media was analyzed descriptively and quantitatively. The sampling technique used was random sampling, in which the entire population has the same rights and opportunities to be involved in research Based on the results of the needs analysis, it shows that 81% of students agree and need AR media to study the optical system of the eye, 72% of students agree that the material for the optical system of the watch has the potential to cause misconceptions if studied without using media. Based on the results of the needs analysis, consists of 3 main topics, namely regarding the structure of the eye, the process of seeing in the eye, and eye defects. The results of the trial analysis using AR media used a paired sample t-test to see the effectiveness of AR media. The results of the analysis of the paired sample t-test showed a Sig.2 tailed value > 0.05 so it can be concluded that there was a significant difference between before and after using AR media. In other words, it is easier for students to understand the material after being treated in the form of AR media on the concept of eye optics.
