Abstract

Rare earth elements are part of one of the strategic minerals and are included in the "critical minerals". Concentrations of rare earth elements are economically precious deposits that can be used as mining commodities. Pumice is the result of volcanic eruptions and it is one of the minerals containing the rare earth elements, one of which is found in Sigura-Gura, North Sumatra. The research aims to determine the composition of rare earth elements, the relationship between rare earth elements and magnetic mineral concentration, and to determine the concentration of magnetic minerals in pumice in Sigura-gura. The method employed is rock magnetic method with Bartington Magnetic Susceptibility Meter Sensor type B (MS2B), and X-Ray Fluorescence (XRF). Results indicated that Sigura-Gura pumice samples, and Sigura-Gura Waterfall have quite varied magnetic mineral concentrations with a range of values from 111,3 x 10-8m3/kg to 349,9 x 10-8m3/kg, with antiferromagnetic magnetic properties and grain types with almost no SP grains. Samples of Sigura-Gura pumice contain elements of Eu, Ce, and Y, while samples from Sigura-Gura Waterfall contain elements of Eu and Y. There is a correlation between the amount of magnetic minerals and rare elements, and the more elements are present in a sample, the lower the value that is produce, and the greater the percentage of elements obtained, the smaller (%) is obtained.

Abstract

City Park Cindua Mato is a green open space located in the center of Batusangkar city and serves as a place for recreation, sports, and social interaction. The existence of facilities such as basketball courts and reflection stone rides make this park an environment rich in phenomena that can be studied scientifically. Despite having the potential of an environment rich in physical phenomena, its utilization in the context of education is still very limited. Problems found based on direct observation show that students often have difficulty in understanding physics concepts because the teaching materials used tend to be theoretical. Observations also show a lack of learner involvement in learning because the media used has not been able to attract their attention, especially those with visual learning styles. In addition, the teacher said that the current teaching materials have not utilized local potential as a source of learning, so students feel that the material presented is less relevant to their daily lives. This research aims to identify the needs of teaching materials that are in accordance with the characteristics of students and the surrounding environment. This research is a preliminary study of the research and development method with the EDUPARK model, which at this stage is focused on the EDU stage. Data were collected through interviews with 3 physics teachers and distributing questionnaires to 31 students of Class XI Phase F Moving Physics 1 SMAN 1 Sungai Tarab. The results of the analysis show that the available teaching materials have not accommodated the local potential and learning styles of students optimally. Therefore, a teaching material is needed in the form of a physics enrichment book integrated with City Park Cindua Mato Batusangkar that is in accordance with the characteristics of students and their learning environment.

Abstract

This research is motivated by the low scientific literacy of students as indicated by the PISA 2022 results, as well as the continued dominance of printed teaching materials in schools. This condition limits students’ opportunities to engage in scientific thinking, interpret data, and use scientific evidence effectively. The purpose of this study is to analysis the need for developing an interactive e-book based on the Dual Space Inquiry Framework (DSIF) on the topic of global warming to improve students’ scientific literacy. The study employed a needs analysis approach within the Analysis stage of the ADDIE development model by collecting quantitative data related to scientific literacy indicators and the frequency of teaching material usage. The analysis shows that all scientific literacy indicators fall into the low category with an average score of 70.3%, particularly in the abilities to interpret data and evaluate scientific arguments. The data on teaching material usage also reveal a dominance of printed books at 91%, while digital teaching materials are used by only 37% of students and interactive e-books by merely 12%. These findings not only illustrate the low level of scientific literacy but also highlight an urgent need for more interactive digital learning media. Based on this analysis, the Analysis stage of ADDIE emphasizes the necessity of developing a DSIF-based interactive e-book as an innovative solution that will proceed to the Design and Develop stages to produce teaching materials capable of supporting inquiry, conceptual understanding, and scientific thinking skills.
