Abstract

This research aims to determine the effect of the thickness of composite boards made from egg cardboard on sound absorption and water absorption. Composite boards are produced by crushing egg cartons with a blender, mixing them with water and tapioca glue to form slurry and then molding them to thicknesses varying from 1, 2, and 3 cm. The sound absorption results were measured using a Sound Level Meter GM1352, while the water absorption capacity was determined using the mass ratio before and after immersion. The results show that the sound absorption capacity of a composite board made from egg cardboard with a thickness of 1 cm is 6.58%, a thickness of 2 cm is 10.87%, and a thickness of 3 cm is 16.05%, while the water absorption capacity of a composite board made from egg cardboard with a thickness 1 cm is 29.41%, 2 cm thickness is 31.43%, and 3 cm thickness is 32.91%. This shows that the greater the thickness of the composite board made from egg cartons used, the greater the sound absorbed. Likewise, with the water absorption test, the results showed that the thicker the composite board made from egg cartons used, the greater the water absorption capacity produced.

Abstract

Innovation in science learning is highly recommended by various studies and education experts. Through this learning innovation, teachers create learning that facilitates students' curiosity by getting them involved in learning, which ultimately helps them understand science in depth. However, the current trend is that science classes "fail" to create innovative learning that can foster students' interest in science, so that many students do not understand science well. This research aims to determine the impact of flipped classroom learning on simple harmonic motion material assisted by computer simulations on students' conceptual understanding. A pre-experiment with a one-group pretest-posttest design was used in this research. Class X of the MIPA program was chosen as the experimental object in this research, and 30 students were used as samples. The test given is a multiple-choice test with explanations. The results showed that the average post-test score was better than the pre-test. The N-gain score is 0.79, which indicates that there is an increase in students' understanding in the high category. This shows that flipped classroom learning assisted by computer simulations can increase students' understanding of the concept of simple harmonic motion. By implementing computer simulation activities that are integrated into flipped classroom learning, learning alternatives can be enriched to help students understand science.
