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 research aims to analyze the needs of students in learning physics related to energy literacy by utilizing the potential of waterfalls as a reference for developing e-modules in Edupark. Methodology: The methodology of this study is survey- quantitative descriptive research. Data collection through questionnaires given to respondents using google form. The research location is at Senior High School 1 Prabumulih, Senior High School 04 Ogan Komering Ulu, Senior High School 1 Merapi Timur, Senior High School 6 Prabumulih, Senior High School 1 Makarti Jaya, Senior High School 1 Bayung Lencir, Senior High School 10 Palembang, Senior High School 2 Palembang, Senior High School 1 Unggulan Muara Enim. Main Findings: The findings of this study tentang Do you think physics is a difficult subject to learn percentage 64%, Have you ever visited a waterfall before percentage 50,1%, Have you ever been taught energy related concepts on waterfalls percentage 31,5%, Have you ever been taught using E-Modules related to waterfall eduparks percentage 51%, Have you ever heard of hydropower before percentage 87,1%, Do you agree that hydropower can provide more stable energy than other renewable energy sources percentage 89,1%. Novelty/Originality of this study: The novelty of this study lies in the e-module associated with the waterfall edupark towards students' energy literacy. The findings can provide new insights in the context of education and researchers to develop appropriate innovations to improve e-modules.
