Abstract

The spread of COVID-19 makes learning at every level of the education unit conducted from home online or distance learning. However, this is not an easy thing for teachers to do. Teachers are required to innovate in delivering materials so that students can easily understand and learn actively. Indonesia is an agricultural country where most of the population has a livelihood as farmers. As a form of contextual learning and alternative distance learning during the COVID-19 pandemic, teachers can take advantage of rice farming activities in Indonesia, known as rice Tandur (reverse planting), as physical science teaching materials. Therefore, this research aims to explore the concept of physical science contained in rice Tandur activities to be used for physical science learning. This research is descriptive research to describe the idea of physical science in rice planting activities. Data collection was conducted by documentation of rice planting activities as well as literature studies. After the documentation is collected, the analysis uses Kinovea software to find out the center of gravity (COG) and the corners formed by the limbs. Based on the results of analysis and literature studies, the concept of physics was obtained in the form of a third-class lever arm that can be used for science materials in high school classes. In addition, there is a center of gravity and torque concept in the torso's movement, which can be used as a material for learning physics in high school.

Abstract

The Covid-19 pandemic has impacted various fields, especially education, namely the implementation of distance learning. One of the activities carried out by teachers is the implementation of independent practicum by students so that teaching and learning activities continue to run even though the students are at home. This study aims to analyze the motion of jumping cats using a tracker application that can be used as a practicum activity independently in science subjects of motion material in grade VII by using cats that are in the environment of learners as the subject of the study. This research method uses a hands-on experimental approach by taking videos of jumping cats' motion and processing them with a tracker app. The results of data processing with the help of tracker application are processed by using Microsoft Excel program so that obtained KD, KB, TB, K and E relationship graphs cat jump has a constant or stable speed indicated by linearity graphs. In addition, data processing using a tracker application is more accurate and consistent compared to the acceleration value by manually calculating so that it can be concluded the use of application-assisted jumping cat video analysis is worth using in science learning.
