Abstract

Geological structures in the Bukit Gadang geothermal area have been identified using the geomagnetic method to determine the type of fault. Data was measured using a magnetometer in the area with dimensions of 1200 m × 1200 m consisting of 144 points at 12 tracks, and the spacing between points was 100 m. Magnetic anomaly data performed diurnal and IGRF (International Geomagnetic Reference Field) corrections. Furthermore, reduced to poles and continuous upwards processes were carried out to remove noise and separate local and regional anomalies. The magnetic field anomaly ​​in the study area ranges from -1771.8 nT to 1089.9 nT, dominated by negative values, indicating the presence of heat sources and the influence of demagnetization of subsurface rocks. The 2D modeling results show that two primary rocks dominate the study area; pyroclastic flow units and andesite lava rock, which come from the Jantan and Batino volcanic formations. The caprock rock layer was identified in the upper layer with a depth of 850 meters. The reservoir rock layer with low susceptibility values ​​was below the caprock layer. The 3D modeling results show a normal fault with a depth of 300-800 meters or at the border of the Jantan volcanic formation with the Batino volcanic formation. The fault line leads to the southeast-northwest (N160°E). The faults obtained from the 2D and 3D models are suspected to be the outflow of geothermal fluid from the reservoir rock layer and form a manifestation in the form of a hot spring at Bukik Gadang.

Abstract

Moringa (Moringa oleifera L.) is a plant belonging to the moringaceae family. Moringa seeds contain oil which can be used as a raw material for making azelaic acid. Azelaic acid is used as an anti-acne in the pharmaceutical and cosmetic industries. Azelaic acid can be obtained from the oxidation process of fatty acids in moringa seed oil using potassium permanganate as an oxidizing agent. The resulting azelaic acid is in the form of white crystals with a conversion percentage of 72.17%. The results of the FT-IR characterization showed the formation of azelaic acid characterized by widening of the hydroxyl group at 3448.46 cm-1 followed by a shift of the ester group at absorption of 1633.46 cm-1. The ester bond is strengthened at a wavelength of 1115.95 cm-1.

Abstract

The implementation of Case-Based learning in chemistry learning has grown rapidly in the last ten years. To find trends and issues in the application of case-based learning in chemistry learning, a systematic review is needed. This study aims to analyze the types of CBL and forms of CBL cases used in chemistry learning. The research method used is a systematic review of articles published in the Scopus journal obtained from the Scopus database for the last 10 years (2011-2021). Search articles using titles, abstracts, or keywords that meet logical conditions (“Case-Based Learning”) or (“Case Method”) and (“Chemistry”). The population of this study was 200 articles published in the Scopus database and the sample used was 93 articles. The findings showed that the CBL learning model has a learning syntax that includes four (4) stages, namely: Case Orientation (determining the object to be tested), Peer Instructions (choosing cases that are relevant to the object being studied), Case Review (building initial theory and reviewing literature), Evaluation (collecting, organizing data, analyzing data and developing conclusions). The CBL model presents complex cases in the form of factual news related to the essence of the problem context in the form of story descriptions and integrates information sources in the context to solve cases. The percentages of the 93 articles analyzed were 32% PBI, 31% PBL, and 30% PJBL. Thus, it can be concluded that CBL learning is implemented in three (3) learning approaches, namely CBL in Inquiry-Based Learning, CBL in Problem Based Learning, and CBL in Project-Based Learning

Abstract

The goal of this study is to create an E-worksheet product based on discovery learning that will help students improve their decision-making skills and scientific attitudes. This E-worksheet was created using the 4D development methodology, which includes the processes of define, design, develop, and disseminate. Students in class XI science SMAN 6 Mataram served as test subjects for this study. The limited trial is taught in one lesson, while the wide trial is taught in two classes. The ANCOVA test, descriptive percentage techniques, and percentage of agreement were used to analyze the data. The practicality data analysis revealed that teachers and students responded with a percentage of 80 and 86.42 percent, respectively, showing that the E-worksheet evolved in the practical category. The results of the effectiveness test using the ANCOVA test obtained Fcount > Ftable (8.28 > 3.98) on decision-making skills and Fcount > Ftable (6.94 > 3.98) on scientific attitude with a significant level of 5%. The null hypothesis (H0) is rejected, which means that E-worksheet influences discovery learning to improve students' decision-making skills and scientific attitudes in grade-eleventh science students. The E-worksheet based on discovery learning is practical and successful for enhancing students' decision-making skills and scientific attitudes toward grade-eleventh science students, according to the research objectives and findings.
