Abstract

Cancer is still one of the leading causes of death in the world. Angiogenesis is the formation of new blood vessels, which plays a vital role in the growth of cancer cells. As a result, inhibition of proangiogenic factors such as vascular epidermal growth factor (VEGF) could be used as a cancer treatment strategy. Black garlic (BG) is processed fresh garlic (Allium sativum L.) for several days under controlled high temperature and humidity. The research aims to investigate the effect of Indonesian local BG on antiangiogenic activity through in vivo and in silico studies. The in vivo test was carried out by observing the formation of new blood vessels using the Chorio-Allantoic Membrane Assay (CAM). The in silico study was performed by docking analysis of BG bioactive compounds on the VEGF receptor (VEGFR). The results showed that ethanol extract, ethyl acetate fraction, and n-hexane fraction of BG inhibit new vessel blood formation, with n-hexane fraction having the highest efficacy. The molecular docking assay indicated some similarities in the amino acids involved in the interaction between the BG bioactive compounds and the native ligand in binding to VEGFR. This similarity may lead to interference with VEGFR resulting in angiogenesis inhibition. The study suggests that BG has the potential to be developed as an anticancer agent, which might be through the mechanism of inhibiting the angiogenesis process

Abstract

This study aims to analyze the characteristics of hydrocarbon chemicals in the Merdeka curriculum and curriculum 13, as well as explore variations of hydrocarbon materials taught by teachers in various schools under the Merdeka Curriculum. The type of research used is descriptive qualitative through survey methods. Respondents in this study involved 24 chemistry teachers who worked in DKI Jakarta and Yogyakarta. The selection of respondents was random. The results of this study show that there are differences in the characteristics of hydrocarbon materials taught in the 2013 curriculum and the Merdeka curriculum. In the Merdeka curriculum, most chemistry teachers still do not differ much from each other even though they have been given freedom in teaching, with only slight variations in the selection of the material. Teachers consider materials in hydrocarbon topics very important and must be taught thoroughly because they will be useful in learning the next topic. In making decisions to teach hydrocarbon material, teachers should increase their understanding of learning objectives, student heterogeneity, limited reference sources, school facilities, and students' initial knowledge.

Abstract

Involving students in active learning is associated with positive learning outcomes. Despite the evidence supporting the positive learning outcomes of active learning, the adoption of active learning has been slow. Numerous education researchers have documented their application of active learning. However, there is no research yet that systematically analyzes these studies regarding the type of active learning implementation in science education. This systematic review analysis study was conducted to review the type of active learning implementation in science education. The main criteria for the selection of articles is the implementation of active learning in the field of science education with a period ranging from 2012 to 2022 from the well-known international database. There were 20 articles were obtained that fit into the criteria using the Active Learning keyword. The review was focused on the course, type of active learning, aims, method, samples, and data collection tools. The results show that the most studied course is interdisciplinary chemistry. Active learning types coded Not applicable, Others, Hybrid learning, Group work, Online-based learning, Hands-on Learning, and Inquiry. Articles aim to investigate active learning effects using quantitative methods. Undergraduate student samples enriched these studies, with data collected through surveys and descriptions. These findings can inspire science educators to adopt suitable active learning strategies, impacting students' achievements in science education.

Abstract

The Aloe vera plant has been widely used as a food ingredient, medicine and cosmetics. This research aims to test the gel and ethanol extract of Aloe vera leaves as an antioxidant and absorber of UV light in vitro, as well as predicting the interaction mechanism for ROS1 kinase and collagenase receptors in silico.The antioxidant activity test method was carried out in vitro using DPPH (1,1-Diphenyl-2-Picrylhydrazyl-Hydrazine) reagent. Activity as a UV light absorber is carried out by calculating the sun protected factor (SPF) value. The antiaging activity test was carried out by predicting the interaction mechanism of the ROS1 kinase and collagenase receptors in silico using several phenolic compounds that have been found in Aloe vera. The total phenolic content of Aloe vera ethanol extract was 379.136 ± 0.34 GAE/g sample, while that of Aloe vera gel was 0.0619 ± 0.04 GAE/g sample. Aloe vera ethanol extract showed moderate antioxidant activity with an IC50 of 101.9 µg/mL, and is able to absorb UV light at concentrations of 0.05% and 0.1% with ultra protection criteria. Several phenolic compounds found in Aloe vera plants showed high binding energy to ROS1 kinase and collagenase receptors. Isoquercitrin showed the highest binding energy to the ROS1 kinase receptor, while isovitexin showed the highest binding energy to the collagenase receptor. The conclusion of this research showed that Aloe vera leaves contain compounds that have potential as antioxidants and antiaging. Keywords: Aloe vera, antioxidant, antiaging, ROS1 kinase, collagenase

Abstract

The research sought to explore how employing the Student Team Achievement Division (STAD) cooperative learning model, along with concept maps, impacts the enhancement of students' self-efficacy and grasp of thermochemistry concepts. This study employed a quasi-experimental approach using a pretest-posttest control group design. It was carried out among 127 11th-grade science students from MAN 1 Bengkulu City, chosen through cluster random sampling. The information was gathered by utilizing self-efficacy questionnaires and conceptual understanding tests and was analyzed using Multivariate Analysis of Variance (MANOVA). The findings indicated that the obtained p-value was less than 0.05 (p<0.05), revealing a statistically significant difference in self-efficacy and conceptual understanding between students in the experimental and control groups. This suggests that students in the experimental group showed greater enhancements in self-efficacy and conceptual understanding when compared to those in the controlled group. Thus, These findings revealed that STAD-cooperative learning with concept maps had a better influence in enhancing self-efficacy and student conceptual understanding of thermochemistry.

Abstract

Science learning based on local wisdom is increasingly gaining attention in the context of learning, especially ethnoscience approach that connects science with traditional knowledge of the local wisdom. This study aims to make science learning more relevant and contextual for students by connecting scientific concepts with local wisdom in the community. The research method used literature review study by collecting reference sources from Google Scholar. Literature studies that examine various studies related to the application of science learning based on local wisdom to use local wisdom in science education in schools. The data analysis technique used in this literature study research is content analysis that contains science process skill and critical thinking skills. The journals that are in accordance with the topic consist of 10 articles. The results of this study indicate that the application of ethnoscience through local wisdom can improve students' understanding of scientific concepts, strengthen their involvement in the learning process, can improve students' science process skills, such as observing, experimenting, analysing, and concluding data, and encouraging the development of critical thinking skills.
