Abstract

The process of utilizing electromagnetic radiation from the radiometric values (Near-Infrared/NIR) and RED in the Normalized Difference Vegetation Index (NDVI) on Sentinel-2 imagery involves measuring light reflection at specific wavelengths reflected by vegetation. NDVI is computed by taking the difference between NIR and RED reflectance, then dividing it by their sum. In-depth analysis of electromagnetic wave interaction and plant spectral characteristics, such as NIR light reflection in healthy leaves, enables mapping vegetation health levels. The research aims to process image data and create a model visualizing vegetation health in the Sentinel-2 research area. Across the total area of 601,971,281.26 m2, 30.37% is healthy vegetation, 12.52% is moderate, and 53.33% is low or unhealthy. The least healthy area has an NDVI of -0.2006, while the healthiest area has a value of 0.6043.

Abstract

The use of conventional teaching materials with less innovative learning models results in a lack of problem solving skills possessed by students. This study aims to produce teaching materials in the form of vibration material e-modules through effective and feasible physics modeling learning to improve students' problem solving skills using the ADDIE development model. The subjects of the research were 34 class XI C students of SMAN 5 Banjarmasin. Data collection techniques using learning outcomes tests through pre-test and post-test. The results showed that the electronic module was stated to be very effective in terms of the average n-gain score for measuring problem solving skills of 0.78 in the high category. As well as there was a significant increase between before and after using the e-module through the paired sample t-test. Thus, the vibration material e-module through physics modeling learning is declared effective and significant in improving students' problem solving skills

Abstract

In the learning process, the learning media acts as a tool. Along with the development of technology, various learning media in the learning process can be used. This study aims to develop web-based interactive learning media on static electricity class IX with a tutorial model and analyze the feasibility of the media in terms of validity, practicality, and effectiveness. The development of learning media uses research and development methods with ADDIE development procedures. Data collection techniques using validity assessment, questionnaires, and tests. The results showed that: (1) this learning media was built using HTML, CSS, Javascript, JSON, and Firebase technologies. (2) the learning media is declared valid in terms of the assessment of the validity of the material and media, practicality in terms of student and teacher response questionnaires is declared practical, effectiveness in terms of student learning outcomes tests with a classical completeness percentage of 80%. Based on the results of the study, it can be concluded that web-based interactive learning media on static electricity class IX with a tutorial model is appropriate to be used as a learning tool.

Abstract

Students' scientific argumentation ability is important in physics lessons but is still not optimal. Therefore, a teaching module is needed that can help develop this ability. This study aims to produce teaching materials in the form of momentum and impulse modules through effective and feasible physics modeling learning to improve students' scientific argumentation abilities. This study uses the ADDIE development model. The subjects of the research trial were 20 students consisting of 2 classes XI A Boys and XI A Girls of SMA IT Arafah Sampit. The effectiveness of learning reviewed from the student learning outcome test obtained an effective category with an average n-gain score of 0.58 which is categorized as effective in measuring scientific argumentation abilities. Thus, it is found that the use of physics modeling learning through momentum and impulse modules can improve students' abilities in scientific argumentation.
