Abstract

This study aims to analyze the content and construct validity of the Ethnoscience–Project-Based Learning (E-PjBL) model for biology education in higher education. The study employed a Research and Development (R&D) approach guided by Nieveen’s educational design framework, focusing on the initial validation stage of model development. The validation process involved six expert validators with expertise in biology education, ethnoscience, instructional model development, and educational research. Research instruments consisted of content validity and construct validity validation sheets using a five-point Likert scale. The collected data were analyzed using descriptive quantitative analysis by calculating mean validity scores and inter-rater reliability using the percentage of agreement method. The results of the study indicate that: (1) the content validity of the E-PjBL model is categorized as very valid, with an overall mean score of 4.97, indicating that the model is developed based on actual learning needs and supported by state-of-the-art theoretical and empirical foundations; (2) the construct validity of the E-PjBL model is also classified as very valid, with an overall mean score of 4.91, demonstrating strong internal consistency among model components, including instructional syntax, learning objectives and impacts, as well as the learning environment and social system. These findings provide empirical evidence that the E-PjBL model is conceptually sound and theoretically feasible for further testing at the stages of practicality and effectiveness in higher education biology learning

Abstract

This study examines respondent and university type responses to science process skills instruments integrated with automated feedback on science practicum performance assessments at 2 state college and 2 private college in West Nusa Tenggara Province. A Kruskal-Wallis test was performed utilizing case study and cluster random sampling. Data was collected using online survey, interviews, and direct observations. Three hundred seventy-six university students and teachers from four universities were studied. Since there was no standard instrument, science process skills performance was not assessed. The assessment results show no statistically significant difference (p > 0.05) between state and private college in measuring science process skills integrated with real-time feedback on science practicum. This suggests that neither university has conducted such an assessment. No significant difference in responses between university students and lecturers regarding the measurement of science process skills on performance assessments integrated with real-time feedback in science practicum (p > 0.05), implying that university students and lecturers have the same experience. This study advises developing science process skills measurement on performance assessment for real-time science practicum feedback.

Abstract

The development of the cosmetics industry in Indonesia is currently very rapid with average market growth reaching 9.67 % per year. The high market potential gives rise to tight business competition in the cosmetics industry, thus encouraging manufacturers to continue to innovate to create new product variations to meet society's demands for cosmetics as a complement to an attractive everyday appearance. This study aims to evaluate the physical characteristics of facial masks, body scrubs and sunscreens from Nyamplung (Calophyllum inophyllum) seed extract at various concentrations (5%, 10%, 15%). The test results showed that the three preparations met the standard physical property test parameters (organoleptic, pH, viscosity, spreadability, etc.). The facial mask formula with 10% extract was most liked by the panelists. Body scrub and sunscreen formulas with 10-15% extract also provide the best physical test results. The SPF value of sunscreen increases with increasing extract concentration up to the ultra category (SPF 17.42 at 15%). This study concludes that Nyamplung seed extract has the potential to be used as a natural ingredient for facial masks, body scrubs and sunscreen with an optimum concentration of 10-15%. Further research is needed regarding antioxidant activity and product stability testing. Overall, the three cosmetic preparations from Nyamplung seed extract show good prospects for development by paying attention to the best extract concentration of each product

Abstract

The problem-based learning (PBL) model is a form of learning that emphasizes the learning process and developing problem-solving skills. The low level of environmental awareness is increasingly worrying. Ecological awareness, in this case ecotourism, is decreasing along with technological developments. For this reason, scientific literacy and environmental awareness are needed, especially in character formation. This article research conducted a systematic literature review using PRISMA approach, namely carrying out a synthesis of studies from articles on the theme of the ecotourism-integrated problem-based learning (PBL) model to increase scientific literacy and environmental awareness. The articles used in this paper are from Google Scholar, scopus and science direct with the application of proportional sampling techniques, 15 of the 72 articles that meet the inclusion criteria, the year of publication between 2020 until 2024, the languages used are Indonesian and English, the research subject is Problem-Based Learning (PBL). The research results show that PBL has positive potential in increasing scientific literacy and environmental awareness. Both the use of the PBL model directly and with integration show an increase in scientific literacy and concern for the environment

Abstract

Multidisciplinary training involving ethnomedicine and ethics, phytochemistry, and antioxidant bioassay analysis requires students to integrate normative reasoning, chemical concepts, and quantitative data analysis. Therefore, foundational competency and assessment quality must be established before diagnostic application. This study evaluated the first psychometric effectiveness of a multidomain idea test and outlined pre-intervention baseline performance across the three domains. The examination was administered to fifth-semester undergraduate pharmacy students enrolled in the Phytochemistry course at the Faculty of Health and Science, UNIQHBA Bagu. A 28-item mixed-format assessment, comprising multiple-choice, constructed-response, and numerical items (maximum score of 32), was administered to N = 41 pupils. Subsequently, descriptive statistics and indices from Classical Test Theory were computed, including Cronbach's alpha, item difficulty (p), D27 discrimination, and adjusted item-total correlations. The most challenging and simplest collections of objects were employed to encapsulate the extreme items. The average total score was 19.90 out of 32 (62.20% ± 13.05%), the median was 20, the range was 11 to 29, and 9 students (about 22.0%) achieved the ≥70 criterion. The performance in the domain was inconsistent. Ethnomedicine and ethics achieved a score of 7.88 ± 1.25 (78.80% of the maximum), phytochemistry received 7.29 ± 2.15 (72.90%), and DPPH–IC50 interpretation got 4.73 ± 2.54 (39.40%). The reliability was acceptable (alpha = 0.756), but the item diagnostics revealed floor and ceiling effects, along with DPPH–IC50 items that were notably challenging. The technique is suitable for initial diagnostic profiling and highlights DPPH–IC50 quantitative interpretation as the main baseline gap, thereby promoting targeted scaffolding and item adjustment to improve differentiation across the ability spectrum

Abstract

This study aimed to determine the effect of the Discovery Learning model assisted by e-modules on students’ physics learning outcomes. This study employed a quasi-experimental design with a nonequivalent control group design. The population consisted of all students of class XI A at SMAN 1 Kediri in the 2025/2026 academic year. Saturated sampling was used, with class XI A2 as the experimental class consisting of 20 students and class XI A1 as the control class consisting of 21 students. The research instrument was a multiple-choice test consisting of 25 items that had been tested for validity, reliability, item difficulty level, and discrimination index. Data analysis techniques included normality testing, homogeneity testing, and hypothesis testing using the t-test. The results showed that the implementation of the Discovery Learning model assisted by e-modules significantly affected students’ physics learning outcomes. This learning model increased students’ engagement in the learning process and encouraged them to actively discover concepts independently. These findings indicate that Discovery Learning assisted by e-modules not only improves students' physics learning outcomes but also promotes active engagement, independent learning, and conceptual understanding in digital learning environments.

Abstract

This study aims to (1) describe the level of student learning activity, (2) describe the level of student physics learning outcomes, and (3) analyze the relationship between learning activity and physics learning outcomes in the implementation of Problem-Based Learning (PBL). This research employed a correlational design with a quantitative approach. The population consisted of all 168 students in the eleventh-grade science classes, and a saturated sampling technique was used so that the entire population become the sample. Descriptive analysis was used to determine the levels of student learning activity and physics learning outcomes. For hypothesis testing, non-parametric statistics (Spearman correlation) were used because the data were not normally distributed. The results showed that (1) the level of student learning activity was 20,8% high, 49,4% medium, and 29,8% low; (2) the level of student physics learning outcomes was 1,2% high, 83,9% medium, and 14,9% low; (3) the Spearman correlation test revealed a significant positive correlation between the two variables (sig. 2-tailed = 0,003 < 0,05) with a low correlation level (correlation coefficient = 0,226). Based on the coefficient of determination, the contribution of learning activity to physics learning outcomes was only 5,1%. Thus, it can be concluded that there is a significant positive relationship between learning activity and physics learning outcomes, although this relationship is low and contributes only slightly.
