Abstract

Waves are vibrations that propagate at any time. Waves are divided into two, namely mechanical waves and electromagnetic waves. In the world of health, what we often encounter are tools whose use is accompanied by one of the physics concepts, namely optical waves. Optical waves in the world of health are very important to apply because they are the basis for learning in health science or in the sense that the concepts that are developed in health science use the concept of optical waves. Optical waves are known as electromagnetic waves, because these waves describe visible light rays, infrared, and ultraviolet rays, so these rays are used as materials for the use of optical instruments. There are many kinds of optical instruments, including loupes which are used to magnify small things, microscopes as a tool to see objects that are far away with the sense of sight, binoculars as a tool to see the distance of objects that are far from the surface of the earth, and the eye as a tool for our vision. Then scientists applied the wave concept with optical tools to serve as a reference in the world of health. Waves according to Prof. Yohanes Surya, Ph. in the title of the book Vibrations and Waves (2019), propagating vibrations produce energy and move at a certain speed, and do not drag the material they pass through. The use of optical waves is widely applied in medical science, including X-rays as a detector for internal body elements to clarify broken parts such as bones or other things. From the explanation above, it can be concluded that waves are the basis in the world of health, which are of course used in optical equipment, and are a reference for the health team and as a basic concept in physics learning. This underlies the fact that optical waves are not only used in the world of education but are very It is also needed in the world of health.

Abstract

Scientific creativity is an important thing that every individual must have to answer the challenges of the 21st century. However, in reality, the results of physics research show that the science abilities of Indonesian students are still relatively low, especially in the fields of creativity and innovation. This study aims to produce project-based student worksheet (LKPD) integrated with valid and reliable PhET. This study uses the research and development (RD) method with a 4D development model, which consists of four stages, namely definition, design, development, and dissemination. The instruments in the study used to collect data were validation sheets and student response questionnaire sheets. The results showed that the LKPD integration of PhET obtained an average validity score of 3.95 and a reliability level of 96.25%, including in the very valid and reliable category. The results of the student response questionnaire showed that 93% responded in the very positive category. The conclusion is that this LKPD integration of PhET is proven to be valid and reliable so that it can be an effective learning material for learning physics on global warming and climate change. This study contributes to the development of innovative and relevant learning media to improve the quality of students' physics learning. The limitations of this study have limitations on the application of the 4D model, which only covers the development and Validation stages. Therefore, the implementation of LKPD in the field is needed to improve the scientific creativity of high school students
