Abstract

The quality of measurement instruments is an essential factor in ensuring accurate and meaningful learning assessments. However, many test instruments have not undergone empirical validation, which reduces their reliability and accuracy. This study aimed to develop and empirically validate a conceptual understanding test on dynamic electricity for high school students. A quantitative descriptive design was employed involving 66 students who had studied the topic of dynamic electricity. Item analysis included validity, reliability, discrimination index, and difficulty level tests. The results showed that 11 multiple-choice items met the criteria for validity and reliability with appropriate levels of difficulty and discrimination. These findings indicate that the developed instrument has good quality and can consistently measure students’ conceptual understanding. Therefore, this test instrument can be used by teachers and researchers as a representative and high-quality tool to evaluate students’ conceptual mastery and improve the quality of physics learning assessment.

Abstract

This study analyzes the management of vocational learning for students with special needs at SLB Negeri 1 Padang by applying the POACE framework: Planning, Organizing, Actuating, Controlling, and Evaluating. The research addresses the problem of inconsistent learning management and limited alignment between vocational programs and students’ functional needs. Using a qualitative descriptive design, data were collected through in-depth interviews, classroom observations, and document analysis involving school leaders, vocational teachers, and students. The data were analyzed through Miles and Huberman’s interactive model: data reduction, data display, and conclusion drawing. The results show that the implementation of POACE is present but uneven. Planning is not yet based on comprehensive student assessments; organizing is hindered by mismatches between teacher expertise and assigned tasks; actuating is limited by insufficient adaptive learning resources; controlling lacks structured monitoring instruments; and evaluation does not include competency measurement or pathways to employment readiness. Overall, the study concludes that vocational learning management requires more systematic, data-driven, and inclusive strategies. Strengthening each POACE component is essential to improving the relevance and effectiveness of vocational education for students with special needs.

Abstract

The transformation of education in the Society 5.0 era has accelerated the integration of digital technology into teaching and learning. This study examines the use of application-based learning media by elementary school teachers in Palembayan Subdistrict, Agam Regency, and explores the factors influencing teachers’ digital competence and the challenges encountered in implementation. Using a mixed-methods approach, data were collected from 99 teachers through questionnaires addressing five core aspects, supported by interviews and field observations. Results show that application usage falls within a moderately favorable range, with most teachers using applications two to three times per week. Frequently used platforms include Canva and Wordwall, valued for their ease of use and support for interactive visual learning. Teachers’ digital skills are influenced by variables such as teaching experience, educational background, device access, and internet stability. Key challenges include limited technological infrastructure, unstable connectivity, and difficulties adapting application features to curriculum content. Despite these barriers, many teachers demonstrate adaptability through independent learning and collaboration. The study highlights the need to strengthen digital competence through ongoing training, promote the development of user-friendly educational applications, and improve infrastructure to ensure inclusive and effective digital transformation in elementary education.

Abstract

This study aims to produce differentiated student worksheets that are valid, practical, and effective in improving students' critical thinking skills. The research and development (R&D) design was conducted using the 4-D model, which consists of four steps: define, design, develop, and disseminate. The research subjects were 15 students in a small-scale trial and 66 students in a large-scale trial, all from class XI of SMA Negeri 1 Seputih Surabaya with cluster random sampling. The trial design used by the researcher was a non-equivalent control group design. The instruments used were needs analysis questionnaires, validity questionnaires, practicality questionnaires, learning implementation observation sheets, and pretest-posttest of critical thinking skills. Data analysis techniques for validity and practicality use descriptive percentage analysis, while data analysis for effectiveness uses statistical analysis (independent sample t-test, paired sample t-test and one-way anova). The results of the development research indicate that differentiated student worksheets are highly valid (94%); differentiated student worksheets are practical for improving students' critical thinking skills in terms of learning implementation; differentiated student worksheets were effective in improving students' critical thinking skills with a large effect size (0.99). The conclusion is that differentiated worksheets on the human digestive system have been developed that can improve students' critical thinking skills.

Abstract

This study examines the factors that influence the success of Industrial Work Practice (PKL) implementation in the Mechanical Engineering Program at SMK Negeri 1 Sumatera Barat. Using a quantitative research design with Partial Least Squares (PLS), data were collected from 58 students who participated in the 2023 internship program. The research investigates the contribution of five variables: productive subjects, general subjects, curriculum alignment, school mentoring, and industrial mentoring. The findings show that productive subjects have the strongest influence on PKL success, followed by school mentoring and industrial mentoring. In contrast, general subjects and curriculum alignment do not demonstrate a significant effect. These results highlight the crucial role of technical competence and consistent guidance in ensuring effective internship experiences. The study emphasizes the need for stronger collaboration between schools and industry to enhance the relevance of vocational learning. It also suggests aligning instructional practices with workplace expectations to better prepare students for real industrial environments. Overall, this research provides empirical evidence that reinforces the importance of practical skills and structured mentoring in improving internship outcomes within vocational education.

Abstract

This study explores high school students’ understanding and attitudes toward environmental conservation grounded in local wisdom as a preliminary step to developing ethnoconservation-based teaching materials. A descriptive quantitative survey was administered to students in coastal and non-coastal areas using a Google Form questionnaire with dichotomous (Yes/No) items. Analysis identified five domains of perception: the importance of integrating local cultural values into science learning, interest in cultural knowledge related to environmental preservation, ability to explain cultural roles in conservation, difficulties in linking ecological concepts with cultural practices, and perceived relevance of local wisdom in science learning. Most students support the integration of local wisdom into science education and express strong interest in learning cultural practices related to conservation. However, many still struggle to conceptually connect scientific concepts with cultural traditions. The study concludes that there is an urgent need for contextualized, culturally responsive teaching approaches that integrate scientific knowledge with local environmental practices to strengthen students’ ecological literacy and multicultural awareness.

Abstract

This study addresses the problem of low science learning outcomes among elementary students by examining whether the Banathy Instructional Design Model can improve performance across different motivation levels. The objective was to compare the effects of the Banathy model and conventional instruction on fourth-grade students’ science learning outcomes while also analyzing the interaction between instructional model and student motivation. A quasi-experimental design with a nonequivalent control group was employed, involving one experimental group taught using the Banathy model and one control group receiving conventional instruction. Data on learning outcomes were collected through a standardized posttest and analyzed using comparative statistical techniques. The results show that students in the experimental group achieved significantly higher science learning outcomes than those taught conventionally. Further analysis indicates that the Banathy model benefits both high- and low-motivation students, although highly motivated students demonstrate the greatest improvement. Notably, even students with lower motivation exhibited better performance when taught using the Banathy model. These findings suggest that the Banathy Instructional Design Model is effective for heterogeneous classrooms and can enhance science learning outcomes regardless of students’ initial motivation levels.

Abstract

Reduced graphene oxide (rGO) is a carbon-based material with high surface area and chemical stability, making it an effective adsorbent for water purification. This study investigates the green synthesis of rGO using Aloe vera extract as a natural reducing agent and its application in treating surface water from the Kapuas River, Indonesia. Graphene oxide was reduced with Aloe vera extract under varying time conditions, and the resulting rGO samples were characterized to confirm the reduction process. The structural and compositional analyses revealed that increasing reduction time enhanced oxygen removal and improved surface morphology. The application tests showed that rGO substantially improved water quality: color decreased from 225 to 95 PCU (57.8% reduction), turbidity dropped from 16.2 NTU to 1.2 NTU (92.4% removal), and dissolved iron concentration decreased from 0.65 ppm to 0.37 ppm (43.07% removal), with pH remaining stable near 6.5. Among all samples, rGO reduced for 120 minutes achieved the highest purification efficiency. These findings demonstrate the feasibility of Aloe vera-reduced rGO as a sustainable adsorbent for surface water purification.

Abstract

Alzheimer disease is one of the causes of dementia that could make the patient lose their memories until they unable to do normal activities. It is caused by accumulation of protein in the brain called Amyloid-β42 (Aβ42), that often used as biomarker for alzheimer by enzyme-linked immunosorbent assay (ELISA). To increase the sensitivity and accuracy, capture antibodies are conjugated with labels such as Horseradish Peroxidase (HRP) and Biotin. However, the two conjugates also differ in sensitivity and specificity, therefore this research is to find which is more optimum and stable for ELISA usage. The molecular mass of the conjugated antibodies was characterized with SDS-PAGE, result shows the pre-conjugated antibody has 150 kDa bands, conjugated antibody with labels is heavier than the pre-conjugated due to the addition of each label. Conjugated antibody tested with tetramethylbenzidine (TMB), then analyzed by ELISA reader. The measurement precision decided with %CV value with results shows dillution from 10-1 to 10-4 has %CV less than 10%, while Biotin is from 10-1 to 10-5. Optimization done by determining fixed antigen with the conjugated antibody, the optimal concentration for HRP is 10-3 while biotin is at 10-4. Stability of the conjugated antibody was also determined, HRP measurement started to unstable around second month and third month, while biotin start to unstable around fourth month, this shows the biotin is more stable than the HRP.

Abstract

Breast milk is the primary source of nutrition for newborns, providing not only essential nutrients but also rich bioactive components with immunological functions. It plays a critical role in the development and modulation of the infant’s immune system, through both innate immune components such as lactoferrin, lysozyme, and immune cells (macrophages, lymphocytes), and adaptive components like secretory immunoglobulin A (sIgA). Stunting in Indonesia is associated with a number of factors, including poverty, low levels of education, poor parenting techniques, and repeated infections that hinder the absorption of nutrients. This review aims to examine the role of breast milk in supporting the infant immune system, particularly in preventing infections, promoting the colonization of healthy gut microbiota, and stimulating mucosal immune development. The method used was a literature review of scientific articles published over the last 10 years (2015–2025) sourced from PubMed, ScienceDirect, and Google Scholar. The findings reveal that exclusively breastfed infants have a lower risk of respiratory and gastrointestinal infections, as well as atopic dermatitis, and demonstrate a more mature immune response compared to non-breastfed infants. The conclusion of this study confirms that breastfeeding significantly contributes to strengthening the infant immune system through immunoprotective and immunomodulatory mechanisms.
