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

This research aimed to determine the effectiveness of electronic-based student worksheets (E-LKPD) on student learning outcomes. The method used was a quasi-experiment with one group pretest-posttest design. The sample taken in a cluster random sampling were 32 students of class VII SMPN 2 Ngemplak Sleman School Year 2021/2022. The instrument used was a problem sheet in the form of a description. The results of the study were analyzed using quantitative descriptive methods. The results of the analysis of the increase in the pretest and posttest obtained an average of N-Gain 0.60 in the medium category. The average pretest value was 6.94 while the average posttest value was 8.80. Test results of t sig value (2-tailed) < 0.05 showed a significant improvement between pre-test and post-test.  This indicated that E-LKPD-based SETS was effective for improving students' cognitive learning outcomes.
