Abstract

Heart disease is one of the leading causes of mortality in Indonesia, yet early detection remains a challenge due to limitations in data and suboptimal classification methods. This study aims to improve the accuracy of heart disease prediction by integrating the Naïve Bayes algorithm with Particle Swarm Optimization (PSO) for feature selection. A dataset of 303 patient records was processed using RapidMiner across three configurations: Naïve Bayes with split validation (80:20), Naïve Bayes with 10-fold cross-validation, and Naïve Bayes with PSO-based feature selection. The results showed that incorporating PSO increased accuracy from 87.60% to 89.26%, along with improvements in precision and recall, while maintaining a high AUC value (0.933). These findings demonstrate that PSO effectively identifies the most relevant features and enhances the performance of heart disease prediction models. The study also underscores the importance of validation methods and model interpretability in the application of artificial intelligence in healthcare.

Abstract

This study aims to isolate and identify terpenoid compounds from kluwih leaves (Artocarpus camansi). Extraction was done using methanol solvent, followed by n-hexane fractionation, which produced a concentrated blackish green extract. Compounds were separated through column chromatography with silica gel as the stationary phase and n-hexane as the mobile phase, and a mixture of n-hexane: ethyl acetate, producing eight fractions. The third fraction, obtained as green crystals, exhibited a positive reaction to the Liebermann-Burchard reagent, a specific test for the presence of terpenoid compounds. The observed colour change indicated the presence of terpenoids, making this fraction a promising candidate for isolation and detailed analysis. After recrystallisation, white needle-shaped crystals were obtained with a melting point of 141–142.8°C. Purity testing using thin layer chromatography (TLC) showed a single spot in various eluents, indicating that the isolated compound was pure. Further characterisation using UV spectroscopy showed maximum absorption at 210.2 nm, while IR spectroscopy showed the presence of OH, methyl, and non-conjugated C=C double bonds. Based on these data, the isolated compounds can be identified as terpenoid compounds. This study provides a basis for further studies on the structure and biological activity of kluwih leaves.

Abstract

Indonesia’s position as the world’s second-largest contributor to plastic waste reflects deeply rooted patterns of unsustainable consumption. Addressing this critical issue requires innovative educational strategies to cultivate environmental responsibility and creative problem-solving in future teachers. This study examines how a guided research-based learning (GRBL) model can transform the perceptions of prospective primary school teachers regarding plastic waste management—shifting from conventional 3R (Reduce, Reuse, Recycle) actions to designing environmentally friendly bioplastics. Employing a one-shot case study design, the research was carried out over one semester in a science education course involving 214 fifth-semester students enrolled in a primary teacher education programme. They were divided into 54 groups. Data were collected through observation sheets, student worksheets, and creativity assessment rubrics. The findings suggest that GRBL prompted students to critically engage with sustainability issues by exploring the biodegradability of various natural materials. Most participants selected starch-based substances due to their accessibility and assumed ecological benefits. However, the resulting bioplastic products predominantly exhibited characteristics of modification and imitation rather than originality or innovation. The proportion of students proposing plastic from organic materials increased significantly from 22.2% to 66.7%, with 27.8% suggesting edible straw ideas. While these developments are promising, the ideas lacked originality and were limited to modifications and imitations. This indicates that while GRBL broadened students’ views on waste solutions, their creative outputs remain limited by insufficient scientific exploration and design experience. The study concludes that GRBL has strong potential to foster sustainability-oriented thinking in teacher education, especially when paired with deeper inquiry and iterative practice. These findings highlight the need for science teacher education to embed structured, hands-on research experiences that connect scientific knowledge with real-world environmental issues, preparing future educators to promote both creativity and ecological awareness in the classroom.

Abstract

Science practicum has an important role in fostering students' scientific skills, but its implementation at the junior high school level still faces various obstacles, such as limited laboratory equipment and practicum guidelines that are not optimal. This study aims to analyze the needs of teachers and students for the implementation of science practicum as a basis for developing guided inquiry-based guidelines. The research method used was descriptive qualitative with data collection techniques through surveys and in-depth interviews. The research subjects consisted of 219 students and 52 junior high school science teachers in the South Sumatra region. The results of the analysis showed that 98.6% of students and 98,1% of teachers stated the importance of practicum guides, while only 34.4% of students and 40% of teachers had used or made inquiry-based guides. The majority of respondents supported the use of the guided inquiry approach because it is believed to be able to improve science process skills. However, limited tools and teacher understanding are the main obstacles to implementation. Therefore, the results of this study emphasize the need to develop guided inquiry-based science practicum guides that are systematic, applicable, and relevant to the context of junior high school learning.

Abstract

The advancement of science and technology requires students to possess strong scientific literacy, particularly in understanding physical phenomena such as elasticity. However, students often demonstrate a low conceptual understanding of elasticity in real-life contexts, posing a challenge in physics education. This study aims to analyze students’ physics literacy skills using the Nature of Science Literacy Test (NOSLiT) instrument. This research employed a descriptive quantitative approach with a sample of 30 students from classes A, B, and C. Data were collected through a written test based on the NOSLiT framework, which consists of six scientific literacy indicators, and analyzed quantitatively using achievement categories. The findings revealed that students' overall scientific literacy achievement was categorized as low (43.2%). The highest achievement was on the scientific evidence rule indicator (58.8%, moderate category), while the lowest was on science process skills (24.3%, very low category). These results suggest the need for more interactive and experiment-based instructional strategies to enhance students’ conceptual understanding. Students' responses were mostly descriptive and lacked evidence-based reasoning, with misconceptions about relationships among physics variables still apparent. These findings emphasize the importance of incorporating scientific practices—such as experimentation, evidence utilization, and contextual problem-solving—into teaching. This study was limited to a single school and instrument, which restricts the generalizability of the results. Future research should include a broader sample and adopt a mixed-method approach to obtain more comprehensive insights. Moreover, the development of inquiry-based learning models is crucial to support the advancement of students' scientific literacy.

Abstract

This study addresses the gap in understanding how personal context influences students’ numeracy skills, particularly in the context of the Minimum Competency Assessment (MCA) in Indonesia. The research problem centers on the challenge of engaging students with numeracy tasks that are not only mathematically relevant but also relatable to their personal experiences. While the MCA assesses mathematical reasoning and problem-solving, students often struggle to apply these skills to real-world scenarios, particularly when the context of the problems is unfamiliar or disconnected from their daily lives. This study aims to analyze the numeracy skills of eighth-grade students in solving problems with a personal context within the Minimum Competency Assessment (MCA). The study employed a mixed-methods design, integrating both quantitative and qualitative data. Quantitative data were analyzed using content validity analysis (Aiken’s V) and inter-rater reliability (Cohen’s Kappa) to assess the validity and consistency of the MCA questions. Descriptive statistics were used to analyze the students' numeracy scores. For qualitative analysis, semi-structured interviews were conducted to explore students' reasoning and problem-solving strategies. The triangulation of data from the MCA tests and interviews provided a comprehensive understanding of how students engaged with mathematical problems and applied their numeracy skills in real-world contexts. A total of 17 eighth-grade students were selected, and three students from each numeracy category; high, medium, and low were chosen using a categorization method based on standard deviation. Results showed that students with high numeracy abilities demonstrated effective problem-solving and reasoning skills, while medium and low numeracy students struggled with complex problems and real-world application. The study suggests that while personal context can enhance student engagement, its effectiveness depends on a solid foundation in numeracy skills. The findings recommend a balanced approach in teaching, strengthening foundational skills alongside contextualized learning. In conclusion, while the personal context in MCA increases student engagement and relevance, particularly among high-performing students, its effectiveness is contingent on a solid foundation in basic numeracy skills. A balanced approach that strengthens basic numeracy skills while incorporating personal contexts is necessary to foster critical thinking and effective application of mathematics across all ability levels.

Abstract

This study aims to evaluate the sensory quality and consumer acceptability of Banjarbaru-produced rice, including fortified (Fortivit), biofortified (Nutri Zinc), and conventional (Inpari 32) varieties, through hedonic testing and sensory attribute analysis. The research was conducted in Banjarbaru City, South Kalimantan, covering five sub-districts. A total of 25 respondents participated in sensory assessments evaluating color, aroma, taste, texture, and shape on a 4-point Likert scale. In addition to sensory analysis, the study investigated zinc retention during typical household preparation practices, including repeated washing and standard cooking procedures. Micronutrient content was analyzed using standard laboratory methods, while sensory data were statistically tested using one-way ANOVA. Results showed that Fortivit rice exhibited the highest consumer preference across most sensory attributes, particularly in texture (mean score 3.60) and color (3.44), and demonstrated superior zinc retention (86.2%) compared to Nutri Zinc (69.8%) and Inpari 32 (74.3%). Statistically significant differences were observed in the attributes of color, texture, and shape (p < 0.05), confirming Fortivit’s sensory advantage. Nutri Zinc, while nutritionally valuable, received lower scores and suffered higher micronutrient losses during washing and cooking. The findings highlight the dual importance of both nutritional resilience and sensory appeal in increasing consumer acceptance of fortified rice. Fortivit’s extrusion-based fortification technology offers an effective strategy for micronutrient delivery, particularly in stunting-prevalent regions like South Kalimantan. This study supports the promotion of fortified rice as a feasible public health intervention and emphasizes the need for continued innovation and region-specific consumer education to ensure adoption success.

Abstract

The Indonesian People’s Accelerograph (ARI) is an innovative ground motion recording device developed using predominantly local, cost-effective components to accurately monitor and record seismic-induced ground acceleration for disaster mitigation. This study aimed to evaluate the instrument response of ARI Type I, which utilizes a MEMS sensor (MPU6050) to capture dynamic acceleration data crucial for earthquake early warning systems. The research involved a comprehensive methodology comprising hardware design, field testing, and in-depth analysis of the instrument’s response by determining key parameters such as gain, poles, and zeros under various seismic conditions. The hardware was meticulously designed using KiCAD, with the final assembly enclosed in a 3D-printed casing that integrates the ESP32 microcontroller, sensor, SD card, and LCD, while data communication was achieved via I2C and WiFi protocols, and time synchronization was maintained using NTP. Field tests conducted at the UNILA site demonstrated that ARI Type I records ground acceleration on all three axes at a density of 50 signals per second. Data retrieved and processed through Python into a DataFrame confirmed the system’s high sensitivity and reliability, with a measured gain of approximately 3637.48 V/g, poles of 1.39133434×10⁻⁸ and 9.10426934×10⁻², and zeros of –1.52128433×10⁻⁶ and –4.69561707×10³. These promising results validate the potential of ARI Type I as an effective tool for seismic monitoring, contributing to the development of robust early warning systems and enhancing disaster resilience in earthquake-prone regions.

Abstract

Understanding how young people perceive renewable and non-renewable energy sources is essential for aligning education with Sustainable Development Goals (SDGs). This study explores the perspectives of 748 Indonesian high school students on solar panel versus fossil fuels through an open-ended question. Different from previous studies, this work uses semantic network analysis to map the conceptual connections in students’ understanding, which provides us a structural perspective on students’ perceptions. Using semantic network analysis with NetMiner, 748 Indonesian students’ responses were categorized into five ideas: Fossil fuels formation (G1), Solar panel role in sustainability (G2), Practical benefits of solar panels (G3), Non-renewable resource concern (G4), and Unsustainable fossil fuels use (G5). The findings indicate that students have a basic understanding of environmental and resource-related issues. Most responses remain surface level with limited demonstration of critical thinking. Furthermore, students’ ideas primarily address the environmental and economic pillars of Education for Sustainable Development (ESD) while the social pillar is rarely discussed. These results highlight the need to improve ESD practices in Indonesia by explicitly integrating social dimensions into sustainability education. Empowering students to consider who is affected by sustainability decisions, and how they can contribute to fairer, more inclusive solutions can help to increase not only environmental awareness but also foster civic responsibility and empathy.
