E-Learning Utilizing Schoology: Teaching Theory of Relativity Using Online

Physics is not only learning through the presentation of concepts or formulas, but many events can be understood through various learning media. Evidently, students better understand the material if they can interact directly with the topic of the lesson. In addition, the rapid internet makes teachers are required to actively develop learning media. This research aims to develop physics learning using E-Learning learning media on the Special Theory of Relativity material for high school students in class XII. This study uses research and development methods that refer to the ADDIE model. This research is limited to making applications. Based on the results of research, this development has produced products that function well and present features that support student learning. Available features include quizzes, learning videos, materials and simulations that students can access. E-learning developed using Schoology can support learning through the online platform. E-learning using Schoology can display the stages of stimulus that can be determined by educators when using this e-learning. Therefore, e-learning learning that utilizes Schoology on relativity material can be designed and developed according to the needs of teachers and students in the learning process in class

PENGEMBANGAN BUKU BHINEKA NUSWAPADA MODEL POP-UP SEBAGAI MEDIA PEMBELAJARAN LEGENDA INDONESIA

Nowadays, most teenagers don't like Indonesian legends because they are considered as old-fashioned and boring stories. The results of a survey of 124 respondents who are teenagers resulted in 85% of respondents consider the legend is not interesting. Whereas 10% of respondents answered interestingly and 5% answered relatively. This study aims to: (i) develop pop-up books that present Indonesian legends for junior high school students, (ii) provide unique and interesting short stories and (iii) illustrate the comparison of student responses before and after using pop-up books as an alternative learning medium. The research method is research and development (R&D). Based on the results of this study, it was concluded that (1) this research produced a product in the form of a pop-up book entitled "Bhineka Nuswapada", 2) a pop-up book worth using as indicated by the results of the student questionnaire responses of 91.15% with the interpretation of the criteria very good and (3) based on the results of the media effectiveness test, after using the pop-up book media there was an increase in student learning outcomes with an N-Gain value of 0.41 on the medium criteria. Therefore, Bhineka Nuswapada is the best alternative medium for learning legend for students

Virtual Reality Media: The Simulation of Relativity Theory on Smartphone

Learning physics science is ideally accomplished through the experiments, although the theory of special relativity is challenging to understand. It is difficult because this topic has not occurred in real experience, and no technology has launched at the speed of light. To understand this theory, Virtual Reality (VR) can potentially visualize the actual concept of relativity by presenting an artificial environment to the students. The aim of this research is to develop the virtual reality application as a learning media for special relativity. This Research and Development uses the Lee and Owens Model, which consists of analysis, design, development, implementation, and evaluation. The system development method used is black-box testing. The result of the development of this system is the creation of a VR application to explain the material of relativity. From the results of black-box testing, the test results show that the percentage of application system success is 83%, which indicates that the application is functioning correctly on smartphone usage so that this application can be used on the theory of relativity simulation users using virtual reality devices

The Defect Analysis of Carbonsteel Pipe Welding Connections Using Non-Destructive Testing with the Penetrant Test Method

In a welding process carried out on metallic materials is sometimes found defects in the material being tested, it is caused by many factors, such as the lack of good materials used and the lack of perfection of the welding process. At testing, it aims to know the surface defects in carbonsteel pipes to know the defects arising after welding. This test is performed with non-destructive tests (NDT) using Dye Penetrant testing method. This test uses 3 types of liquids, including; Cleaner, Penetrant, and developer. The results of these tests will then be observed whether defects occur after welding and what factors affect it. From the test, results there are known 10 locations defects on the surface of the carbonsteel pipe welding with a type of rounded indication of defects that are then followed up by re-welding on indications of such defects
