Abstract

This research aims to develop interactive learning media based on PowerPoint in the learning of Natural and Social Sciences (IPAS) for the material of plant body parts in elementary schools. The research method uses the ADDIE development model (Analysis, Design, Development, Implementation, Evaluation). The analysis stage is used to identify learning needs and student characteristics. At the design stage, the media is designed with relevant visual content and supports interactivity. The results of the development are then implemented in the classroom and evaluated through observation, interviews, and questionnaires. The results show that this learning media improves students' understanding plant body parts material and increases learning motivation. Features such as animation and multiple choice evaluation help students understand the material more concretely and interestingly. Teachers also find it helpful as it presents the material in a systematic and structured way. With this media, the learning process becomes more effective, interesting, and relevant to the needs of students in the digital era. This research recommends training for teachers and further development for other IPAS materials.

Abstract

The Alpine region of Europe, which covers several countries including France, Switzerland, Italy, Austria and Germany, is characterised by its complex geology and significant geothermal potential. This research investigates the geochemical characteristics of geothermal water in the Alpine region, focusing on understanding the origin, evolution, and potential applications of these geothermal resources. Through comprehensive hydrochemical and isotopic analyses, we have identified key geochemical signatures that distinguish the various geothermal systems in the region. The results show that these geothermal waters are mainly influenced by deep magmatic processes, extensive water-rock interactions, and mixing of meteoric and magmatic fluids. Elevated concentrations of elements such as sodium (Na), lithium (Li), and chloride (Cl), as well as different stable isotopes, provide insights into the thermal and geochemical environments of geothermal reservoirs. Based on isotopic analysis oxygen (δ¹⁸O) and hydrogen (δ²H), the most of the geothermal water in the Alpine mountain region of Europe is of meteoric origin (derived from meteoric waters). The isotopic composition can reveal the mixing between meteoric and magmatic water. Intermediate values between GMWL and magmatic water compositions indicate such mixing, helping to understand the fluid dynamics within geothermal systems. This research underlines the importance of integrating geochemical studies in the exploration and management of geothermal resources in tectonically active regions such as the Alps.

Abstract

Proton therapy is an advanced treatment method for cancer that uses protons to irradiate tumors with high precision. However, the high energy of protons requires effective shielding to protect the surrounding environment and personnel from radiation exposure. In this research, the radiation shielding performance of Portland material was evaluated using the PHITS version 3.351 simulation software. The study focuses on assessing the attenuation of radiation within the cyclotron room under various operational conditions. The effectiveness of radiation shielding made from Portland material in a 230 MeV, 300 NA cyclotron room for a proton therapy facility was investigated. The results from PHITS simulations provide insights into the potential of Portland material in reducing radiation levels in proton therapy rooms, contributing to the safety and efficiency of such facilities. This analysis is essential for optimizing shielding design and ensuring compliance with safety regulations in proton therapy facilities.

Abstract

Research this aiming for develop and describe validity as well as practicality of learning media based on Articulate Storyline 3 in the material classification creature life with approach scientific at Junior High School 2 Panti. Research using the 4D development model to stage distribution limited. Products validated by experts materials, media, language, and practitioners, then tested its practicality through trial scale small (10 students) class VIII) and scale large (32 students) class VII). The validation results show a very high level of validity with average scores from each validator: subject matter experts scored 95.31%, media experts scored 96.25%, language experts scored 100%, and practitioners scored 100%. Furthermore, the practicality test results showed a score of 88.75% in the small-scale test and 91.07% in the large-scale test, which falls into the “very practical” category. With thus, the learning media developed stated to be very valid and practical for used in science learning.
