Abstract

Lagrange's equation is a formula in analytical mechanics used to solve problems with physical system dynamics. It allows mathematical modeling to simplify complex mechanical problems by changing the coordinate system, thus providing a deeper understanding of motion. In this research, a literature study was conducted using the Systemic Literature Review (SLR) method from 30 data sources, 24 of which were indexed by Scopus. A total of 11 articles have been reviewed with a focus on the application of Lagrange's equation in various technologies. The review results show that Lagrange multipliers provide a powerful tool for optimizing energy flow within complex smart grids. The benefits extend beyond smart grids. Lagrange's equations are a powerful mathematical tool applicable to various engineering challenges that involve finding optimal solutions under constraints.

Abstract

Purpose of the study: This article will focus on the validity criteria, with the aim of this research being to assess the extent to which the physics learning media specific to the parabolic motion subtheme in the form of videos developed can be considered valid. Methodology: This study used research and development (R&D) with the Alessi and Trollip model. The data collection technique was carried out through a validation sheet instrument conducted by 5 expert validators. The development of learning videos was carried out for class XI Senior High School 22 Palembang. Main Findings: The assessment of the content aspect of the material resulted in a CVI value of 0.93. Furthermore, the evaluation of the media presentation aspect attained a CVI score of 1, and the validation of the productivity and innovation aspects of the material also scored 1. Since the CVI scores are all at 1, it can be inferred that the instructional video created is both valid and appropriate for educational purposes. Novelty/Originality of this study: This research makes a real contribution in answering the needs of modern learning with the STEM approach and AI technology. The results of this media validation are expected to be a reference for further research and become an inspiration for educators in developing innovative learning media.

Abstract

The rapid development of technological advances has changed the paradigm in education, especially in learning innovation. This service aims to improve the quality of teachers in designing and making products in the form of animated videos. The technological innovation guided in this service is to produce animated videos as learning media. Participatory Action Research (PAR) is a method used in the implementation of service activities with stages: 1) giving an initial test, 2) service implementation activities, 3) evaluation and reflection stages, and 4) then giving the final test. The target participants of the service activities were the MGMP teacher community of science subjects in Palembang City. Based on the data obtained, there is an increase in test results with an N-gain of 0.56 which is included in the moderate category. Based on the above results, the training participants strongly agreed that this service activity could improve the skills and insights of teachers in making animated videos as science learning media
