This study aims to analyze the concept understanding and concept understanding constraints of students of class XI IPA 1 SMA Negeri 1 Dolok Batu Nanggar on thermodynamic material in physics lessons.

The research method used in this research is a quantitative descriptive method with a research sample of 30 students of class XI IPA 1 SMA Negeri 1 Dolok Batu Nanggar. The instrument used is a questionnaire containing questions about thermodynamic concepts.

The results showed (1) The understanding of the concept of students in class XI IPA 1 at SMA Negeri 1 Dolok Batu Nanggar is categorized as moderate in terms of understanding the concept of Thermodynamics material in physics lessons with a percentage of 50%. (2) The highest obstacle experienced by students of class XI IPA 1 at SMA Negeri 1 Dolok Batu Nanggar in understanding the concept of thermodynamic material in physics lessons is the lack of supporting resources such as textbooks or additional learning materials which makes thermodynamics difficult to understand by students with a percentage of 80%. (3) The concept of thermodynamics that is most difficult to understand by students of class XI IPA 1 at SMA Negeri 1 Dolok Batu Nanggar in thermodynamics material is that students find it difficult to understand the carnot cycle series shown in a graph with a percentage result of 63.3%.

This research aims to determine the development of digital literacy-based learning videos mitigating flood and landslide disasters that meet valid and effective criteria. This type of research is research and development (R&D) with the DDD-E development model consisting of the stages of decide, design, develop, and evaluate. The subject of this study consisted of 2 validators, 1 educator and 22 students of class VII Junior High School Negeri 1 Masamba. The determination of the validity criteria of the magazine uses the aiken V index test with three components of material expert assessment criteria, namely material, presentation, and language aspects, as well as three media expert assessment criteria namely display, sound and text, and presentation. The results of this study showed that the video met the validity criterion with aiken index values V= 0.83 and V=0.81. The effectiveness rate of the magazine showed that 79% of the overall number of learners and 100% of educators responded very positively after using the magazine. In addition, learning results obtained by learners after using digital literacy-based learning videos based on flood and landslide disaster mitigation were obtained 100% of learners obtained learning knowledge above KKM and in test analysis t-1 samples obtained a significant value of 2 tailed < 0,05. Based on these data it can be concluded that digital literacy-based learning videos of flood and landslide disaster mitigation are valid and effective.
