Abstract
The 2013 curriculum requires a balance between developing attitude competence, knowledge and skills. In addition to equipping students with knowledge and skills, students need to develop attitude competence. In the learning process, it is also necessary to use ICT. This study aims to determine the effectiveness of using physics e-books based on problem-based learning, which is integrated with landslide mitigation material on attitude competence. This study describes the results obtained during the assessment phase, especially on attitude competence. This type of research is Research and Development (R&D). The development model used is the Plomp development model, which consists of three stages: the preliminary phase, the development or prototyping phase, and the assessment phase. The instrument used in this study was a self-assessment questionnaire. This study concludes that the problem-based learning physics e-book with the theme of landslides effectively develops students' attitudes. This research implies that there is a development in students' problem-solving skills and that students understand how to mitigate landslide disasters.
