The Implementation of Strain Liquefaction Learning Package to Cultivate the Critical Thinking of High School Students

Abstract

This study aims to explain the potential of liquefaction in Padang Lekat Village and Pasar Ujung Village Kepahiang District, explaining the feasibility of developed learning packages, and explaining students' critical thinking skills after learning the wave material through the learning package "Strain Liquidity Learning". The type of study used was research and development which aims to develop digital-based physics learning packages that are integrated with disaster mitigation education on the basic competencies of waves in high school education units. This research was conducted using ADDIE development research procedures. The results of research on the analysis of liquefaction potential based on microtremor data using the Ground Shear Strain method, zoning indication of liquefaction potential due to geological conditions and seismic potential, generally Padang Lekat Village and Pasar Ujung Kepahiang Village are areas that have no potential to experience liquefaction. However, there are a number of locations indicated by potential liquefaction, although not significantly. Learning Package Book "Learning Liquid Strain" compiled based on the analysis of liquefaction potential based on expert validation is appropriate to be used as a learning medium for seismic and liquefaction waves. In its application with distance learning, the compiled learning package book has been able to improve critical thinking skills in students even though the N-gain improvement obtained is still in the low and medium categories.
