Abstract

Abstract:This research is an experimental study that aims to support the temperature and variation of doping in making thin films. The temperature variations at room temperature annealing, 50, 100, 150, and 200oC, and doping variations of 0, 5, 10, 15, 20, and 25%. The method used in this study is sol-gel spin coating. The results showed that thin films at low temperatures were more transparent than higher temperatures and the increase percentage doping causing thin films to be more transparent. Keywords:Thin Films; SnO2; Indium, Sol-gel, Spin Coating.

Abstract

Abstract: This study aims to produce a product in the form of a science learning model for the acquisition of motion material concepts in valid objects, with the development path using a 4D model consisting of 4 stages of development namely define, design, develop, and disseminate. Learning tools developed are syllabus, Lesson Plain, SAS and tests of critical thinking skills and student learning outcomes. However, at this writing focused on the process of validation testing through validation tests on the development of devices made. The final result of this study is to produce valid learning development products. Keywords: Learning Devices, Validation

Abstract

Abstract: This study aims to produce learning media in high school grade XII science quantum phenomenon material. This research is development research that uses the research and development model of Borg and Gall with ten stages, but in this study only followed until the fifth step. Data from development research results in the form of a percentage of the validity of learning media from the validation sheet in the form of responses and suggestions obtained from the test results by material experts and media experts. This learning media is supported by a syllabus, learning implementation plans, and student worksheets as well as instruments for understanding students' concepts and critical thinking skills. The focus of this research is the validity test by material experts, media experts on the media developed. The results of the learning media validation from the test subjects were declared appropriate for use. Keywords: Learning Media; Quantum Phenomenon; Validation
