This research aims to determine the effect of physics learning media assisted by the Canva application on interest in learning. The type of research used is quasi-experimental, with a nonequivalent control group design. The population is all students in class XI Science, with samples taken from class XI IPA 1 and class Based on the pretest results that have been analyzed, the average score is 87.8 for the experimental class, while in the control class the average score is 87.1. This shows that the initial abilities in both classes are almost the same. Based on the posttest results that have been analyzed, it can be seen that there was an increase in interest in learning in physics subjects after being given treatment in the form of learning media assisted by the Canva application in the experimental class, which can be seen in the average score of 119.0, whereas in the control class which only used media. conventional power points obtained an average score of 107.9. So it can be concluded that interactive learning media such as Canva has an influence on interest in learning. Because by using Canva as a learning media that is interesting and relevant to students' daily lives, it can trigger curiosity with various kinds of critical questions which then motivate students to get involved in the physics learning process, so that they can increase interest in learning physics learners.

This research aims to develop a physics learning module integrated with the concept of Islamic-science at Madrasah Aliyah which is sought to meet the criteria of valid, practical and effective in the learning process. This module is designed by integrating Al-Quran verses and hadith on each subject matter of physics discussed. This research uses a Research & Development approach with the ADDIE model which includes the stages of Analysis, Design, Development, Implementation, and Evaluation. The research was conducted at MAN 1 Majene, West Sulawesi. Data were collected through questionnaires and learning outcome tests. The results of the development of Islamic-science integrated physics learning modules are (1) declared valid with an average score of 3.05 from 3 expert validators; (2) declared practical by getting positive response scores from students during the learning process in terms of its use; (3) analysis of learning outcomes from all three aspects (cognitive, psychomotor, affective) is classified as effective with a good category. Based on these results, the physics learning module integrated with Islam-science meets the criteria of valid, practical, and effective.

Development of a Three-Tier Multiple Choice Diagnostic Test to determine the level of misconceptions of SMA/MA students regarding temperature and heat.The use of a three-tier multiple choice diagnostic test instrument can determine the level of student misconceptions. This research and development aims to determine the level of student misconceptions regarding temperature and heat material. This research is R&D research with a 4D development model. This research used 3 validators and 30 research subjects in class XII MIA 2 MAN Binjai. The percentage of students who experienced the most misconceptions was 90% in question 10. The average percentage of students who experienced misconceptions was 58.2%. Based on the results obtained, the three-tier multiple choice diagnostic test instrument developed was effective in determining the level of misconceptions experienced by students regarding temperature and heat material so that the questions could be distributed.

Development of Local Wisdom-Based Physics Teaching Materials for Grade X Students at SMAN 4 Maros. Aims to assess the validity and reliability of physics teaching materials based on local wisdom, as well as evaluate students' conceptual understanding and responses to these materials. The research and development method used is the 4-D model, which includes defining, designing, developing, and disseminating. However, dissemination was not conducted in this study due to time and budget constraints. The product was validated by media experts, subject matter experts, and physics teachers, with the research subjects being tenth-grade students at SMAN 4 Maros. The product's instrument sheets were tested for validity and reliability, and the assessment results were analyzed descriptively. Several findings indicate that the evaluation of the teaching materials showed high validity in the material aspect with a score of 3.5 (Very Valid) and a reliability of 0.947 (Very Strong), as well as in the media aspect with a score of 3.55 (Very Valid) and a reliability of 0.947 (Very Strong). The average evaluation score of the students was 13.125 (Very Good). Additionally, the questionnaire results indicated a "Very Positive" response to the physics teaching materials by 87% of the 40 participating students. Based on these assessments, the developed module is deemed highly suitable for use.

PENGARUH PENGGUNAAN ALAT PERAGA SMART TRASH BIN TERHADAP PEMAHAMAN KONSEP FISIKA MATERI TEKNOLOGI DIGITAL

Pengaruh Penggunaan Alat Peraga Smart Trash Bin Terhadap Pemahaman Konsep Fisika Materi Teknologi Digital. The purpose of this study is to determine the understanding of the concept of digital technology classes taught and not taught using smart trash bin props, knowing the difference in understanding the concept of digital technology classes taught and not taught using smart trash bin props. The type of research is experimental with a posttest-only control design. The instrument used tests the understanding of concepts. Data analysis techniques use descriptive and inferential analysis. The average score of concept comprehension test results in classes taught using smart trash bin props was 80.42, with a very high category, while in classes that were not taught using smart trash bin props, it was 76.04, with a high category. The average value of the concept understanding test results taught with smart trash bin props is greater than the average value of the concept understanding test results that are not taught using smart trash bin props, so it can be concluded that the use of smart trash bin tools has a positive influence on the understanding of the concept of digital technology material. Meanwhile, the results of hypothetical testing obtained a significant value of 0.194 > 0.05, meaning that there was no significant difference in understanding of concepts between classes taught and not taught using smart trash bin props.

Rectal cancer is one of the deadliest cancers in Indonesia. Treatment of rectal cancer is often done with radiotherapy. External radiotherapy of rectal cancer uses linac which has several methods of irradiation. This study aims to determine the distribution of photon doses through the Conformity Index (CI) and Homogeneity Index (HI) values as well as the doses received by healthy tissue around cancer tissue. This study also aims to find out better methods of external radiotherapy. Making treatment planning using Xi-O TPS software. This study on the 3DCRT method produced HI values of 0.084 ± 0.017 and CI values of 0.98 ± 0.02. In the IMRT method, the HI value is 0.099 ± 0.028 and the CI value is 0.96 ± 0.03. Based on HI and CI analysis, it was found that the 3DCRT method was better than IMRT in the treatment of rectal cancer but not significantly. Meanwhile, the IMRT bowel bag method has a lower average dose compared to the 3DCRT method and the results are significant. In bladder and femoral tissues, the IMRT method is better than the 3DCRT method but is not significant. In rectal cancer, the IMRT technique is better because it can minimize the dose of OAR.
