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

The development of information and communication technology in Indonesia has developed very rapidly. This can be seen in smartphone users, the number of bloggers in Indonesia, Facebook or other social media users, and internet users. One of the information and communication technologies that is starting to develop in Indonesia is Virtual Reality. This technology in Indonesia is still not much developed. Virtual Reality technology that has entered Indonesia is mostly only in the form of games. There are not many Virtual Reality developers in Indonesia. The Indonesian government itself is currently promoting the digitization of school (learning) materials, one of which is through the Electronic Book Series from the Ministry of Education and Culture for elementary school, junior high school high school and vocational school children. Electronic Series Books are still limited to masters or digitalized books, while the development of Virtual Reality in the education sector in Indonesia is still not large and has not yet developed. In Indonesia, almost no elementary schools utilize Virtual Reality technology in their learning process and mathematics is one of the school materials that is very feared by students, apart from English and regional languages ​​(Javanese). From the above background, researchers developed a mathematics learning application for the elementary school level based on Virtual Reality technology. With this Virtual Reality technology, children are invited to play and learn so that children are able to work on math problems in a fun way

Abstract

Performing experimental activities in a laboratory using the available equipment is not as straightforward as it may seem. In practice, conducting experiments can be challenging, and various factors can contribute to erroneous measurement results. One such factor is systematic errors, which occur due to inaccuracies in the measurement tools used. Additionally, error sources from external factors can also influence the measurement results. It is important to be aware of these potential errors and take appropriate measures to minimize their impact during experimental procedures. Tracker software is a valuable tool that can enhance the accuracy of experimental activities conducted in laboratories. This software assists in generating more precise data by tracking and analyzing various elements of the experiment. By utilizing tracker software, researchers can closely monitor the movement and behavior of objects, making it easier to measure and record data accurately. This technology plays a significant role in improving the reliability and efficiency of experimental procedures in the laboratory setting. From the study's objectives, it can be deduced that the restitution coefficient values obtained through manual data collection for the bekel ball are 𝑒 = 0.5136 ± 0.004214, and for the ping pong ball, it is 𝑒 = 0.4566 ± 0.01736. On the other hand, when using tracker software for data collection, the restitution coefficient value for the bekel ball is 𝑒 = 0.5397 ± 0.0008731, and for the ping pong ball, it is 𝑒 = 0.5115 ± 0.001154.

Abstract

Natural science learning is a process of discovery, therefore science learning includes systematic exploration activities, which means not only mastering systematic accumulation but also the process of discovery. It's helps aid participants in solving problems. However, the phenomena encountered show that students' problem-solving abilities are still quite low. The low problem-solving ability is also influenced by students' self-efficacy. Therefore, it is necessary to innovate the development of science learning tools using appropriate models. One model that can be use is the integrated PBL model with the STEM approach. The development carried out aims to increase students' problem-solving abilities and self-efficacy. This type of research is R&D research with the ADDIE development model. Study findings indicate that students' problem-solving abilities have increased by 0.81 in the high category and their self-efficacy has increased by 0.30 in the medium category. These findings are based on the acquisition of the N-gain value. Consequently, it is beneficial to increase students' problem-solving skills and self-efficacy to design science learning resources that incorporate the PBL model and the STEM approach.
