Abstract

This research was motivated by the low scores obtained by grade 8 students of Bintang Mulia Junior High School in Science-Physics subjects about simple harmonic vibrational materials. The influence of teachers who are very dominant and students who are less active causes a lack of student understanding of the subject matter, resulting in 52% of students obtaining scores below KKM 71. This is what encourages learning improvements that emphasize improving teacher performance in using teaching aids and applying the STAD type learning model. Learning improvement aims to increase students' understanding in science learning, especially harmonious vibration material. This research was conducted in grade 8 of Bintang Mulia Junior High School, Bandung city in the first semester of 2022. The method carried out in this study is Classroom Action Research which consists of two cycles of learning improvement. The instruments used in this study were teacher performance reflection sheets and student learning outcomes tests. Data from teacher performance research in applying learning outcomes were also obtained student learning results about harmonic vibrations from cycle I (73.4) and cycle II (91.4). After teachers improve their performance by using the Student Team Achievement Division (STAD) learning model and using teaching aids in the 1st and 2nd cycle learning process, it can be concluded that there is an increase in student learning outcomes. Thus improving teacher performance using the Student Team Achievement Division (STAD) learning model can be applied in other materials and in other schools.

Abstract

Atomistic simulation based on computational physics of methods is used to develop accurate interatomic potentials based on DFT (density functional theory) data. The accuracy of predicting the physical properties of a material is highly dependent on the quality of the interatomic potential used. The purpose of this study is to determine the Lennard-Jones potential parameters of Al metal (epsilon and sigma) from fitting the DFT simulation output data. The use of a “robust” fitting method to reduce the influence of outliers on the potential results is very important and therefore a machine learning method is used to help find the right potential parameters. The method used is a hybrid method using DFT to generate training data, using ML (machine learning) to fit DFT data to the Lennard-Jones (LJ) potential model, and using the MD (molecular dynamics) method to validate the LJ potential parameters. Python-based programming is applied to facilitate how the three methods can be connected. The results of this study are that Al metal has an epsilon value = 0.5000 eV and sigma Al = 3.2072 Å, with a regression coefficient R2 = 0.9441 so that it can be concluded that this study can be said to be quite good and the hybrid method can be further developed to obtain the LJ potential parameter values of various other materials, especially metals.
