Abstract

This development research aims to create a product in the form of Power Point Visual Basic Application (PPT VBA) media based on the Numbered Heads Together (NHT) cooperative model on valid, practical, and effective business and energy materials, so that it can be used to measure motivation and mastery of concepts. students at school. The type of research used is research and development (Research & Development) with the ADDIE model, namely analysis, design, development, implementation, and evaluation. Data collection techniques were obtained from the results of filling out the validation sheet by 6 validators, namely 3 expert validators and 3 practitioner validators using a Likert scale. Practicality is obtained from the results of student response questionnaires. Effectiveness was obtained from a learning motivation questionnaire and a concept mastery test. Validity is obtained from the results of the validity assessment by expert validators and practitioners, namely 84% and 89%, respectively, with very valid categories. Practicality is obtained from the results of the student response questionnaire with an average value of 99.45% in the very practical category and gets a positive response. The effectiveness is obtained from the results of the motivation questionnaire after learning with an average value of 71.09% in the high category and the results of the concept mastery test calculated using N-Gain getting an average value of 0.59 in the medium category. So that it can be concluded, the development of PPT Visual Basic Application media based on the cooperative model of the NHT type is valid, practical, and effective to increase learning motivation and mastery of students' concepts on business and energy materials in school learning

Abstract

The aircraft used in this study is the upper wing type which has the advantage of flight stability. This upper wing aircraft was designed by the researchers themselves with three different types of wings with a wing span of 1.35m and a fuse lag of 0.925 meters. There are four main forces that work when the plane is in the air, namely lift, thrust, air resistance and gravity. From the results of this study, it can be concluded that the heavier the aircraft unit being flown, the greater the minimum thrust required to fly the aircraft. The measurement results of the 3 aircraft weights, namely 917 grams, require a thrust of 2030 grams of force, whereas for a total aircraft weight of 1,230 grams a thrust of 2510 grams is required, and at an aircraft weight of 1495 grams a minimum thrust of 3040 grams is required. The results also show that the thrust generated is not linear with the throttle position

Abstract

This study aims to analyze the use of Google Forms as an evaluation tool for learning physics in Phase F at SMAN 1 Masbagik. The analysis was divided into two, namely students' mastery of physics concepts on Fluid Statics in terms of the question categories and students' responses to the use of google forms. This study used 18 respondents from Phase F at SMAN 1 Masbagik, East Lombok Regency, West Nusa Tenggara. This research was conducted in an odd semester of the 2022 school year. The link to the evaluation questions given to respondents contained 15 questions with 5 answer options, namely A, B, C, D, and E. Links to student response questionnaires for using the evaluation tool in the form of a Google form containing 10 attitude statements, with an assessment using a scale of 4. The results showed that students who answered correctly in the easy category were 72.2%, the medium category was 50.0%, and the difficult category was 33.3%. Students who expressed interest in the Google form as an evaluation tool amounted to 35.7%, and students who stated that they were very satisfied with the Google form as an evaluation tool amounted to 42.9%. Thus, teachers need efforts to train students in working on questions that fall into the difficult category or Higher Order Thinking Skills (HOTS). The Google form can be an alternative evaluation tool in physics learning, especially during the COVID-19 pandemic which limited direct learning interactions in class
