Abstract

This research was conducted because there are learning activities that do not use learning media, especially technology-based; teaching materials still only use books, and still use the lecture method, causing students to get bored easily, and less interested when learning material is explained, causing a lack of knowledge, apart from critical thinking skills. students are still relatively low. The aim of this research is to improve students' critical thinking skills through MABER, which is the learning media used in this research. This interactive multimedia contains material examples of energy and energy changes in everyday life, media in science and technology subjects in grade IV SDN 05 Ngasem Batealit Jepara. This research uses the Pre Experimental Designs type, with a research design namely One Group Pretest-Posttest. Non-test data collection techniques include observation and interviews and test techniques in the form of pretest and post-test questions. The data analysis technique uses the N-Gain test to determine the increase in students' critical thinking by giving pretest and post-test questions with MABER media. Improving the critical thinking abilities of class IV students through MABER media was carried out through One Group Pretest-Posttest research by giving questions according to critical thinking indicators before and after using MABER learning media. The aim was to determine the increase in students' critical thinking abilities. The results of the pretest and posttest were tested using the N-Gain test. This research showed an increase in the critical thinking skills of class IV students by 0.60 in the medium category. In conclusion, the existence of MABER (Interactive Multimedia in the Form of Energy) media has succeeded in improving the critical thinking skills of fourth-grade elementary school students.

Abstract

This study aimed to evaluate the effectiveness of Video-Based Laboratories (VBL) in enhancing critical thinking skills among state Islamic senior high school (Madrasah Aliyah Negeri) students in Hulu Sungai Tengah, Kalimantan Selatan, specifically in the context of rotational dynamics. Using a quasi-experimental design, we compared the performance of an experimental group that utilized VBL with a control group that followed traditional teaching methods. Data were collected through pretest and posttest assessments on critical thinking skills, and various statistical analyses were performed, including the paired samples t-test, Wilcoxon signed-rank test, and Mann-Whitney U test. The findings indicated significant improvements in critical thinking skills for both groups; however, the experimental group demonstrated substantially greater gains. This suggested that VBL, through interactive and hands-on learning methods, effectively enhanced critical thinking skills in physics education. The results underscored the potential of integrating VBL into physics curricula to foster deeper understanding and reflective reasoning. Future research should explore the long-term impacts of VBL and its application in diverse educational settings.

Abstract

Hazardous and Toxic Waste (B3) from laboratories, especially those containing heavy metals (Hg and Cr) and several physical factors such as pH, TSS, and color, poses a serious threat to the environment if not managed properly. This study aims to estimate the adsorbent for the development of laboratory-scale wastewater treatment equipment based on the adsorption method using biochar, zeolite, and activated alumina. The research method involves preparing adsorbent materials, testing their effectiveness in reducing the content of heavy metal pollutants, and designing a waste treatment device. The combination of biochar, zeolite, and activated alumina was chosen due to their complementary abilities in removing heavy metal content from B3 waste in the Soil Chemistry laboratory. The treatment results showed significant reductions (p < 0.05) in heavy metal (Hg and Cr) levels in laboratory waste. The optimal combination is a formulation of biochar, zeolite, and activated alumina (1:1:1). Innovations in adsorbent technology for processing heavy metal waste in soil chemistry laboratories can be applied and further developed to create a clean and healthy environment.

Abstract

Education in Indonesia requires the utilization of technology to improve the quality of learning. The Web-Enhanced Course (WEC) model offers flexibility in accessing learning materials while supporting the effectiveness of face-to-face instruction. Google Sites serves as a relevant medium, integrating text, video, and interactive features that foster students’ motivation and engagement. This study aims to develop physics learning media based on the Web Enhanced Course model using Google Sites, focusing on renewable energy topics, to evaluate its feasibility and assess students’ responses in grade X of senior high schools. This research employed a development method adapted from the Borg and Gall model, which consists of seven stages. Data collection instruments included expert validation sheets for media and material, as well as student response questionnaires. Data were analyzed using descriptive statistical analysis to determine the level of feasibility and attractiveness of the developed media. The results indicated that the physics learning media based on WEC, with the aid of Google Sites, were highly feasible, with material expert validation reaching 85% and media expert validation at 86%. The small-group trial obtained 89%, and the field trial achieved 90%, both categorized as very interesting. Educators and students responded positively to the media in terms of ease of use, material relevance, and engaging presentation. The media has the potential to enhance students’ conceptual understanding of renewable energy and strengthen the integration of digital technology in physics learning. More broadly, this study contributes to the development of 21st-century learning models that are collaborative, interactive, and grounded in digital literacy. Further research is recommended to examine the effectiveness of this media on other physics topics and in diverse educational contexts.

Abstract

The Microteaching course trains students to understand basic teaching skills and apply them in teaching practice with fellow students. The purpose of this study was to determine students' explanation skills during teaching practice in the microteaching course. The study was conducted with Biology Education students enrolled in the Microteaching course, class A, during the 2024/2025 academic year. Data were collected using observation sheets during student teaching practice through peer teaching. The instrument used was derived from indicators' explanation skills, with answer choices on a 1-5 Likert scale. The data were analyzed descriptively by calculating the scores obtained by each indicator on the observed explanation skills, then 5 categories were created: very poor, less good, quite good, good, and very good. The results of observations on all observed explanation skills indicators showed that, on average, students were able to apply explanation skills in teaching practice in micro teaching courses with a good category. However, there were still students with very poor and poor presentations, with an emphasis on important points, and feedback indicators. It can be concluded that, on average, students were able to apply explanation skills in teaching practice; however, they still need to continue practising so that, later, when facing school field practice or when becoming real teachers in schools, they become accustomed to using these skills.

Abstract

Environmental attitudes among university students play a crucial role in supporting the achievement of the Sustainable Development Goals through the development of responsible and sustainable behaviors. This study aims to analyze university students’ environmental care attitudes in the context of the Sustainable Development Goals (SDGs). A descriptive quantitative approach was employed, involving 121 students from the Chemistry Education Program, Faculty of Teacher Training and Education, Universitas Mataram. Data were collected using a 5-point Likert scale questionnaire covering three primary dimensions of environmental attitude-cognitive, affective, and conative-along with a commitment dimension toward the SDGs. The results indicate that all dimensions fall within high to very high categories, with the highest averages observed in the cognitive (4.32), affective (4,18) and SDGs commitment (4.25) dimensions. The conative dimension scored slightly lower (3.89), suggesting the existence of an attitude–behaviour gap between awareness and actual practice. Students demonstrate strong environmental knowledge and moral commitment, but have not fully translated these into consistent, sustainable behaviors. These findings underscore the need for more contextually relevant and action-oriented learning strategies based on the SDGs, such as project-based learning and eco-campus programs, to translate environmental awareness into tangible actions. Overall, the study emphasizes the strategic role of higher education in cultivating knowledgeable, committed, and sustainable-minded youth aligned with SDG 12, SDG 13, and SDG 15.

Abstract

Calotropis gigantea (L.), commonly known as biduri, is a plant recognized for its pharmacological properties, including antioxidant and anti-inflammatory activities, largely attributed to its secondary metabolites, particularly flavonoids. The concentration of these bioactive compounds is strongly influenced by the environmental conditions in which the plant grows. Geothermal manifestation areas, characterized by extreme abiotic conditions, can induce metabolic responses in plants, potentially enhancing flavonoid production. This study aimed to determine and compare the total flavonoid content in ethanolic leaf extracts of C. gigantea collected from geothermal and non-geothermal areas in Aceh Province. Extraction was conducted using 96% ethanol, and total flavonoid content was quantified using UV-Vis spectrophotometry via the aluminum chloride (AlCl₃) complexation method. Quercetin served as the standard, and flavonoid levels were expressed as milligrams of quercetin equivalents per gram of extract (mg QE/g). The calibration curve showed a linear relationship between quercetin concentration and absorbance, with a regression equation of y = 0.0101x – 0.0098 (r = 0.9417). The results demonstrated significant differences in flavonoid content between samples from geothermal and non-geothermal sites. C. gigantea plants from geothermal areas exhibited altered flavonoid levels compared to those from non-geothermal regions, indicating that environmental factors play a role in modulating the biosynthesis of these bioactive compounds.

Abstract

Science education plays a critical role in shaping students' scientific literacy and attitudes. Teachers' perspectives on the nature of science (NoS) are central to how science is taught in classrooms, particularly at the elementary level. This study aims to analyse the views of elementary school teachers in Indonesia on the fundamental characteristics of science and how they implement these views in their teaching practices. Using a descriptive quantitative approach, complemented by Focus Group Discussions (FGD), data were collected from 52 teachers across diverse geographical regions, including West Nusa Tenggara, Java, and East Nusa Tenggara. The data were analysed based on four core aspects of the nature of science: science is interesting to study, science is useful in life, science continues to develop, and science is a global human endeavour. The results show that most teachers have very positive views on the first three aspects, while their understanding of the global dimension of science is categorised as good. Further analysis revealed no significant differences in teachers' views based on length of service, gender, or PPG (Teacher Professional Education) status. These findings suggest the need to enhance teachers' pedagogical competence through globally oriented training programs and contextualised science teaching approaches. This study contributes to improving the quality of science education by encouraging a more holistic and globally relevant understanding of science among primary school teachers.

Abstract

Scientific literacy is an important indicator in the implementation of science education, which must be integrated systematically at all levels of education. This study aims to investigate the differences in scientific literacy skills between classes taught using interactive learning media and those taught using conventional learning media, with a focus on the sub-topic of the circulatory system. Additionally, it aims to assess the changes in scientific literacy skills before and after the use of interactive learning media on the sub-topic of the circulatory system. The type of research employed was quasi-experimental, utilising a non-equivalent control group design with data collection techniques that included pretests and posttests of scientific literacy. These tests were used to evaluate the hypothesis through independent sample t-tests and paired sample t-tests. The study's results showed differences in scientific literacy abilities between classes taught using interactive learning media and those taught using conventional learning media in the sub-material of the circulatory system. The results of this study also indicated a difference in scientific literacy skills before and after the use of interactive learning media in the sub-material of the circulatory system. This study demonstrates that the use of interactive learning media that present content related to scientific phenomena can enhance students' scientific literacy skills. This research highlights the importance of utilising interactive learning media for teachers in enhancing students' scientific literacy.
