The Validity Of The Integrated Physics Ebook On Landslide Disaster Mitigation Materials Based On A Problem Based Learning Model

Education aims to prepare students to have a number of competencies and abilities to face life's challenges. One form of life's challenges is the threat of natural disasters from the environment where students live, such as landslides disaster. Landslides have a bad impact on the environment and can even threaten survival. The impact of landslides can be minimized by mitigating disasters. Mitigation is an effort made to reduce and minimize the consequences of a disaster, which includes preparedness, alertness and capability. Mitigation activities can be carried out through education in schools by integrating landslide disaster mitigation materials into teaching materials for physics subjects. This study aims to determine the validity of the integrated physics ebook on landslide disaster mitigation materials based on a problem-based learning model. This research uses the research and development (R&D) method with the Plomp model which is limited to the second stage, namely the development or prototyping phase. The developed physics ebook was tested for validity by experts. The instrument used in this study was a validity questionnaire consisting of four aspects, namely the feasibility of the content, the feasibility of presentation, the feasibility of language and the feasibility of graphics. The results showed that the integrated physics ebook on landslide disaster mitigation materials based on the problem-based learning model was in the valid category so that it could be used in physics learning in schools
