Abstract

The growing demand for sustainable materials in additive manufacturing has driven interest in biocomposite filaments reinforced with natural fillers. In this study, ABS-based biocomposite filaments reinforced with oil palm empty fruit bunch (OPEFB) microfibrillated cellulose were successfully fabricated using a single-screw extrusion process. The OPEFB cellulose content was varied from 0 to 30 wt.% to evaluate its effect on filament dimensional stability, morphology, and chemical structure. Filament extrusion was performed at a processing temperature of 220 °C and an extrusion speed of 850 to ensure stable melt flow and minimize thermal degradation. The results show that the filament diameter remained relatively stable within the range of 2.50-2.80 mm across all compositions, indicating good dimensional control during extrusion. This study highlights the novelty of successfully fabricating ABS-based biocomposite filaments reinforced with OPEFB microfibrillated cellulose using a simple process. SEM analysis revealed that low OPEFB content (2 wt.%) resulted in uniform filler dispersion and good interfacial bonding, while higher filler loadings led to increased porosity, agglomeration, and surface roughness, which may adversely affect filament quality and printability. The current findings demonstrate that OPEFB can enhance filament characteristics even at low composition scales. The presented results are comprehensive enough for initial filament characterization, including dimensional stability, morphology, and chemical structure, which adds to the interest of this study and has not been previously presented. FTIR analysis confirmed that no chemical modification occurred between the ABS matrix and OPEFB cellulose, with interactions dominated by physical bonding. Overall, the findings demonstrate that ABS-OPEFB biocomposite filaments with low to moderate cellulose content can be effectively produced and show potential for fused deposition modeling applications, offering a sustainable alternative to conventional ABS filaments.

Abstract

This study aims to analyze research trends regarding the Argument-Driven Inquiry (ADI) model in science education. A Systematic Literature Review (SLR) was conducted using the Scopus database, following PRISMA 2020 guidelines. From an initial 20 records identified, 11 high quality original articles published between 2019 and 2025 met the strict inclusion criteria. The findings indicate that while publication numbers appear to fluctuate, this is largely attributed to ongoing data indexing for the year 2025 rather than a decline in academic interest. The ADI model is most frequently implemented at the secondary school level, particularly in Physics and Chemistry. Results demonstrate that ADI significantly enhances scientific argumentation, conceptual mastery, and critical thinking. Furthermore, technical modifications such as rADI and MADI have proven effective in addressing diverse student needs and classroom constraints. In conclusion, ADI serves as a robust framework for 21st-century science learning, though future research must prioritize long-term sustainability studies and teacher professional development to ensure successful implementation across broader educational contexts.

Abstract

Diabetes mellitus is a degenerative disease closely associated with oxidative stress, with a high prevalence in Indonesia reaching 19.5 million cases in 2021. Stevia leaves and soursop leaves have an antioxidant composition with the ability to protect humans from free radicals and prevent oxidation. Soursop leaves and stevia leaves are one contain bioactive compounds with antioxidant and antihyperglycemic properties, making them potential ingredients for functional beverages. This study aimed to formulate a herbal tea combining soursop and stevia leaves and to evaluate its bioactive content, product quality, toxicity, and antihyperglycemic effectiveness. Three formulation ratios (75%:25%, 50%:50%, and 25%:75%) and brewing times of 3, 5, and 7 minutes were investigated. The evaluated parameters included total soluble solids, color intensity, pH, total phenolic content, antioxidant activity, sensory characteristics, and heavy metal contamination analyzed using ICP-OES. The best formulation was obtained at a 25%:75% ratio with a brewing time of 7 minutes. The selected product was further assessed for toxicity using the Brine Shrimp Lethality Test (BSLT) and for antihyperglycemic activity in alloxan-induced male mice, with ethical approval No. 1306/KEPK/USU/2025. Data were analyzed using two-way ANOVA followed by Tukey’s test (α = 0.05). The BSLT results showed an LC₅₀ value of 562 ppm, indicating low toxicity. In the antihyperglycemic test, a dose of 5.6 mg/kg body weight resulted in the greatest reduction in blood glucose levels (46.15%). Overall, the herbal tea combining soursop and stevia leaves was found to be safe and demonstrated potential as a functional beverage for diabetes prevention.

Abstract

The rapid advancement of digital technology and artificial intelligence has reshaped the landscape of physics education, emphasizing the need for instructional models that effectively promote students’ critical thinking skills. This study aims to synthesize and map the development of Hybrid STEM–Project-Based Learning (STEM–PjBL) models supported by web-interactive learning environments and deep learning approaches in physics material education. A hybrid review method was employed, integrating a Systematic Literature Review (SLR) and bibliometric analysis of 30 peer-reviewed articles indexed in Scopus and SINTA from 2020 to 2026. The SLR results indicate that STEM-oriented PjBL consistently enhances students’ critical thinking, problem-solving, and conceptual understanding, particularly when implemented through authentic and interdisciplinary projects. Bibliometric findings reveal a growing research trend toward web-based learning and artificial intelligence, with deep learning emerging as a promising yet underexplored component within STEM–PjBL frameworks. However, empirical integration of adaptive deep learning mechanisms in physics material learning remains limited. This study contributes by highlighting critical research gaps and proposing a conceptual Hybrid STEM–PjBL Web-Interactive Model with Deep Learning, which integrates pedagogical design, digital interactivity, and intelligent adaptability to optimize critical thinking development. The findings provide theoretical, practical, and methodological insights for advancing AI-enhanced STEM education.

Abstract

This study aims to develop and implement instructional media in the form of Canva-based animated videos to improve students’ conceptual understanding of Food Webs in the Natural and Social Sciences (IPAS) subject for Grade V elementary school students. The development model employed is the Alessi & Trollip model, which consists of three main stages: planning, design, and development. The research subjects were Grade V students who participated in the learning process using the developed media. Research instruments included expert validation sheets, practicality questionnaires, and learning achievement tests in the form of pretests and posttests. The validation results indicate that the media achieved a very valid category, with an average score of 87.07%, covering language, content, and media aspects. Practicality testing conducted through individual trials and small group trials also showed very high results, with percentages of 97.33% and 74.40%, respectively. Effectiveness testing at the field trial stage revealed a significant improvement in students’ learning outcomes, with an average N-Gain score of 0.63, which falls into the moderate category. These findings demonstrate that Canva-based animated videos are effective in enhancing students’ conceptual understanding through the presentation of material that is visual, interactive, and contextual. Therefore, this instructional media is feasible to be implemented as an innovative alternative in IPAS learning at the elementary school level to strengthen concept mastery and increase students’ learning motivation

Abstract

Health promotion media is a communication tool designed to accelerate education towards sustainable development (SDGs) in the health sector. Digital learning is an option to reduce limitations in the learning process. This study aims to determine the effectiveness of knowledge of health promotion media before and after digital learning. The research method is a pre-experiment with a one-group pretest-posttest design without control. The number of samples was 38 Level I students in the odd semester of the 2026/2027 academic year, obtained by purposive sampling. The data collection method used a critical knowledge instrument in the form of a questionnaire. The results of the normality test showed that the data were not normally distributed, with a Wilcoxon pairwise correlation test p-value <0.05, meaning there was a difference in the average ability of participants in knowledge of health promotion media before and after digital learning. The average grouping of student knowledge based on the N-Gain value ≥0.30, namely 0.33 - 1.00, concluded that students' abilities in knowledge of health promotion media after effective digital learning improved better (medium category). This is because digital learning is a supporting factor in the health education movement.

Abstract

This study aims to develop and evaluate a digital Student Worksheet (LKPD) for IPAS learning on the topic of plant parts for fourth-grade elementary school students. The research employed a Research and Development (R&D) approach, which included the stages of needs analysis, design, development, and product testing. Expert validation was conducted by subject-matter experts, media experts, and language experts to assess the feasibility of the content, visual design, language use, and usability of the digital LKPD. Practicality testing was carried out through one-to-one evaluation and small group testing, while effectiveness was analyzed by comparing pretest and posttest scores and calculating students’ N-gain values. The results indicate that the digital LKPD demonstrates a high level of validity and practicality, with the content, media, and language aspects categorized as very valid, and good ease of use and acceptability observed in the practicality tests. Analysis of learning outcomes shows an increase in students’ average scores from pretest to posttest, with the average N-gain falling into the high category, indicating that the digital LKPD supports students’ conceptual understanding of plant parts. This study concludes that the use of digital LKPD can serve as an alternative interactive learning medium that promotes active student engagement; however, further testing on other subject matter and with larger samples is needed to strengthen these findings.

Abstract

Abortion represents a public health challenge at the intersection of clinical safety, ethics, and law; limitations on access to safe abortion services are likely to incite a channel push to informal/illegal abortion, specifically via digital modalities. The legal framework in Indonesia is primarily restrictive with limited exceptions, which means that uncertainty around legal boundaries, stigma and barriers to accessing care can generate demand for information and illegal abortions. This study combines an evidence mapping integrated review using the PICo/PEO framework to synthesize the cross-disciplinary evidence across three pillars, including sexual-reproductive health (SRH) science, transcendental ethics, and legal literacy (criminal–health–pharmaceutical–digital regulation). The search was performed through health, education and legal databases and a two-stage selection process as per the PRISMA principles and extraction was performed from a thematic-operational matrix. The review invariably found that the strongest prevention hinges on the development and implementation of a three-pillar curriculum, along with case/vignette-based pedagogy, medico-legal risk literacy, and online information sorting competency. Evidence mapping the strengthening of legal literacy and design due diligence platform as a strategic node to reduce demand and suppress the circulation of illegal abortion drugs.

Abstract

Urbanization pressures and land conversion in Probolinggo City in recent years have increased the risk of discharge reduction and degradation of recharge zones at three main springs: Senthong, Grinting/Sumber Wetan, and Umbul/Ganesha. This study aims to analyze the distribution of power, interests, and conflicts in urban spring conservation. The approach used is a qualitative case study through in-depth interviews, focus group discussions (FGDs), and policy document analysis. The analysis is grounded in Stakeholder Theory using a power–interest matrix instrument to map actor configurations and their relational dynamics. The findings indicate that local government and the water distribution operator (PDAM) occupy dominant positions (high power), while business actors fall into the category of powerful beneficiaries. In contrast, local communities have high interests but low power. This pattern produces pseudo-collaboration practices, in which communities are only involved at the socialization or ceremonial stage, with no role in determining tariff policies, distribution allocation, or conservation priorities. This imbalance triggers latent conflict between exploitation-oriented interests and ecosystem protection agendas. The study concludes that spring conservation requires a governance design that corrects power asymmetry through the establishment of formally legalized cross-actor collaborative forums and the granting of community-based management rights over recharge areas as a mechanism for strengthening substantive participation.

Abstract

Limited rain gauge coverage and uneven station distribution remain major challenges for hydrological analysis in ungauged watersheds. This study calibrated and evaluated GPM IMERG satellite rainfall for estimating annual maximum daily rainfall (AMS) in the Rea Watershed, Indonesia. AMS data from four rain gauge stations (Tepas, Taliwang, Seteluk, and Pototano) were used as ground observations, while nine GPM grid cells represented spatial rainfall over the watershed. A rainfall-range-based multiplicative correction was applied using gauge–satellite AMS pairs. Performance was evaluated using Percent Bias (PBIAS), Root Mean Square Error (RMSE), Mean Absolute Error (MAE), and Sum of Squared Errors (SSE), followed by leave-one-station-out (LOSO) validation. Uncorrected GPM data showed systematic underestimation, with PBIAS of -17.7%, RMSE of 66.64 mm, and MAE of 48.67 mm. After optimized correction, PBIAS shifted to +13.8% and MAE slightly improved to 47.97 mm, but RMSE increased to 75.82 mm and SSE to 201,213 mm2. These results indicate that the correction reduced bias but did not improve overall accuracy. LOSO validation produced RMSE values of 50.83-72.13 mm, indicating sensitivity to station omission. Overall, GPM rainfall can support preliminary AMS estimation in ungauged areas, but its application should be treated cautiously because of persistent uncertainty in extreme rainfall estimation.
