Abstract

Eucalyptus is a plant that is able to absorb gold (Au) particles from the soil and store them in the leaves. Eucalyptus roots have the ability to penetrate the soil of the calcrete zone, which is rich in the mineral calcium (Ca). Calcium is a chemical element with the symbol Ca and atomic number 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. and contains Au particles as impurities, making this plant a potential natural indicator (biogeochemical) of potential Au metal mining. The Au content in eucalyptus leaves can be determined by using the XRF (X-Ray Fluorescence) instrumentation material analysis method for qualitative analysis and AAS (Atomic Absorption Spectroscopy) for quantitative results. The form of XRF characterization of the intensity versus energy spectrum of certain elements from the XRF analysis results obtained is a spectrum with a peak power of 9.731 keV which indicates the presence of Au metal in the sample. The results obtained qualitatively are the Au metal content in the eucalyptus leaf sample of (9.0 ± 0.5) ppm. However, the Au metal content in each leaf sample was different. This provides information that Eucalyptus from different plants has the potential to be a biogeochemical indicator of potential Au metal mining in Indonesia

Abstract

21st-century learning presents chemistry teachers with new challenges in teaching abstract chemistry concepts with various technologies that continue to develop. One of the media that can visualize abstract chemical concepts is Augmented Reality (AR). AR media developed in chemistry learning needs to be valid so that it can be used properly. Therefore, this study aims to examine the validity of the Android-based AR media developed. Four education practitioners carried out the validation as experts, and 13 students participated as respondents. The instrument used is a questionnaire with a Likert scale. The data obtained were analyzed quantitatively with the Rasch model using the facet software. The results of the analysis show that the Exact Agreements are 41.10%, and the Expected Agreements are 42.20%. The most challenging aspect to achieve is media design, while profit is the most easily agreed-upon aspect. Based on this assessment, in the development of augmented reality media, it is necessary to pay attention to display aspects and 3D objects suitable for viewing a material so that it is easier for users to understand the material.

Abstract

Behind the successful of teaching using the problem-based learning (PBL) model, -in our best knowledge- it seems that the factors that make its implementation successful in the classroom have not been mentioned, this is related to the purpose of improving student learning outcomes. For this reason, the study of the implementation of the PBL model needs to be explored further. Specifically, the aim of our current study is to evaluate student learning outcomes in implementing the PBL model and reflecting on the learning process using this model. This study is a Classroom Action Research (CAR), which is an examination of activities or actions that are intentionally conducted in a teaching. In the context of this study, the observation is carried out by evaluating student learning outcomes, while the activity or action that is carried out is Problem-Based Learning (PBL) which is carried out in two learning cycles. The subjects for implementing the PBL model were 21 students in an Islamic school (MTs NW - equivalent to Junior High School) in Central Lombok, Indonesia. Quantitative and qualitative approaches were used to analyze student learning outcomes and the learning process using the PBL model. The results of the study showed that there was an increase in student learning outcomes from the first cycle to the second cycle. Individual and classical completeness has been achieved in accordance with predetermined criteria. Finally, we recommend the use of the PBL model for the purpose of improving student learning outcomes. In the PBL model, the role of motivation, cues, encouraging active student participation, and the use of scaffolding are important aspects in the successful implementation of the PBL model

Abstract

To promote the application of the STEM approach in science learning, it is necessary to provide cheap, easy-to-obtain, and effective STEM project support materials. In addition, science teachers should try to plan and implement STEM in their teaching, even for simple projects. To overcome the problem of the length of time on projects in science teaching, we propose "STEM at Home", a term that means that STEM projects are carried out by students at home under the supervision of parents or families. In order for this home project-based learning to be effective, we have prepared a STEM at Home Kit and Worksheet for Junior High Schools students. We chose the topic Simple. The STEM at Home Kit and Worksheet that have been developed, have received expert approval as learning media that are suitable for use. One-to-one evaluation with 3 participants, and a small group evaluation with 14 participants, were carried out to obtain feedback on students’ difficulties in using the product, their perceptions of the product, and their perceptions of the potential impact produced by the instructional product. The results of this evaluation showed that the STEM at Home Project Kit and Worksheet are valid and practically used in science learning, especially on the topic of Simple Machine
