Abstract

This study aimed to evaluate the effectiveness of cassava starch-based edible films enriched with Senduduk fruit extracts (Melastoma malabathricum) and tomato fruit extracts (Solanum lycopersicum) in preserving the quality of galamai during storage. Galamai is a traditional food product prone to oxidation and quality deterioration, necessitating packaging that can extend its shelf life. Edible films were selected as a biodegradable packaging alternative that functions not only as a barrier against oxygen and water vapor but also as a carrier for natural bioactive compounds capable of enhancing product stability. A Completely Randomized Design (CRD) was employed, utilizing various concentration combinations of the senduduk and tomato extracts. Observed parameters included the antioxidant activity and physical characteristics of the edible films, as well as the chemical and sensory quality of the galamai during storage. The results indicated that the incorporation of senduduk and tomato extracts into the edible films influenced antioxidant activity, film physical properties, and galamai quality stability. A balanced combination of senduduk and tomato extracts yielded the best results in preserving *galamai* quality during storage, evidenced by increased antioxidant activity, maintained physical film characteristics, and the inhibition of lipid oxidation in the product. Furthermore, *galamai* packaged with these edible films demonstrated superior sensory acceptance compared to other treatments. Overall, the combination of senduduk and tomato extracts in edible films shows potential as an effective active packaging solution to extend the shelf life of *galamai* by enhancing antioxidant stability and inhibiting oxidative degradation during storage.

Abstract

Indonesia continues to face a high maternal mortality rate (MMR), partly due to low compliance with antenatal care (ANC) visits despite the national recommendation of at least six check-ups during pregnancy. This study aimed to evaluate the effectiveness of digital technology-based health education in improving ANC compliance among pregnant women in several Puskesmas working areas. A longitudinal intervention study with a quantitative pretest–posttest design was conducted involving 30 respondents selected using G-Power and distributed across three Puskesmas. The intervention consisted of structured health education delivered through digital media. The findings showed a significant increase in ANC compliance after the intervention in all locations, with statistical analysis indicating p < 0.05, confirming the effectiveness of digital-based education in improving routine examination adherence. The results demonstrate measurable behavioral change following the intervention, reflected in higher compliance levels post-education. This study contributes to science-based health education by demonstrating that digital learning media can function as an applied, contextual approach to strengthening maternal health literacy and promoting evidence-based behavioral change

Abstract

Atopic dermatitis increases susceptibility to Staphylococcus aureus colonization, while increasing antibiotic resistance underscores the need for alternative antibacterial agents. This study provides antimicrobial activity and synergistic potential of limonene and salicylic acid—two essential oil components commonly found in Indonesian plants—against S. aureus ATCC 25923. The antibacterial effect was measured using the inhibition zone diameter (IZD) and minimum inhibitory concentration (MIC) assays. Limonene produced the largest inhibition zone at a concentration of 400–500 mg/mL, while salicylic acid showed optimal inhibition at 100 mg/mL. The combination of the two with a 1:9 ratio produced the largest inhibition zone of 20.35 mm, with the volume ratio significantly affecting the IZD value (P < 0.001). The MIC results showed that limonene and salicylic acid had MIC values of 62.5 mg/mL and 6.25 mg/mL, respectively. The 1:9 combination substantially reduced the MIC to 0.12 mg/mL (0.01 mg/mL limonene and 0.11 mg/mL salicylic acid). A FICI value of 0.01 indicates a very strong synergistic effect (FICI ≤ 0.5). Overall, the combination of limonene and salicylic acid demonstrated significantly enhanced antibacterial activity compared to the individual compounds, supporting their potential as a synergistic alternative natural antibacterial for managing S. aureus-associated skin infections

Abstract

This study aimed to synthesize empirical evidence on the effects of inquiry-based learning on senior high school physics learning outcomes through a Systematic Literature Review (SLR). The review followed the PRISMA 2020 guidelines. Relevant studies were identified from Google Scholar, Scopus, Springer, and ERIC using predefined search terms. Articles were selected through identification, screening, eligibility assessment, and quality appraisal based on explicit inclusion criteria. Twenty peer-reviewed studies published between 2020 and 2025 were included in the final synthesis. The findings indicate that inquiry-based learning consistently improves students’ critical thinking, conceptual understanding, science process skills, learning motivation, and engagement. However, its impact on cognitive learning outcomes varies depending on teacher guidance, instructional quality, students’ readiness for inquiry, learning modalities, and the integration of digital technologies such as PhET simulations and virtual laboratories. The review also identifies guided inquiry, teacher readiness, learning resources, and process-based assessment as key moderating factors influencing implementation effectiveness. Overall, inquiry-based learning is an effective instructional approach for senior high school physics when supported by appropriate instructional design, adequate learning resources, and authentic assessment practices. These findings provide evidence-based recommendations for educators, curriculum developers, and future research on inquiry-based physics education

Abstract

The role of visual learning media is crucial in enhancing the education experience, helping students engage with the material, understand abstract science concepts, and improve learning achievements, especially in the topic of Plant Body Parts in science learning. However, the integration of interactive and technology-based media in classroom learning remains limited. This study aimed to develop a valid, practical, and effective Augmented Reality (AR)-based BUCARA Flipbook for fourth-grade students. The novelty of this study lies in integrating AR technology with an interactive flipbook designed to support elementary science learning through visual and contextual experiences. This research employed a Research and Development (R&D) approach using the ADDIE model and involved 29 fourth-grade students at SD Negeri Gunungpati 02 Semarang. Data were collected through observation, interviews, questionnaires, and pretest–posttest assessments, then analyzed using quantitative and qualitative methods. The results showed that the AR-based BUCARA Flipbook was categorized as very feasible with a validation score of 95% and received highly positive responses from teachers and students. The paired-sample t-test indicated a significant difference between pretest and posttest scores (Sig. 2-tailed = 0.000 < 0.05). In addition, the N-Gain score of 0.7374 indicated a great improvement in students' learning outcomes. In conclusion, the AR-based BUCARA Flipbook is an innovative and effective learning medium for improving elementary students' IPAS learning outcomes.

Abstract

The increasing demand for sustainable electricity generation highlights the importance of efficient wind power optimization, particularly in island regions with variable wind resources such as Ambon City, Indonesia. This study proposes an intelligent optimization framework based on the Queen Honey Bee Migration (QHBM) algorithm to improve wind power generation performance. A simulation model of a grid-connected wind energy conversion system was developed, integrating aerodynamic turbine modeling, generator dynamics, and power conversion stages. The optimization process aims to determine optimal operating conditions that maintain the turbine at an optimal tip speed ratio (λ) by adjusting controllable operational parameters, including blade pitch angle (β) and generator operating conditions. The proposed QHBM approach is evaluated using representative wind speed profiles ranging from 6–14 m/s derived from seasonal coastal wind conditions in Ambon. For benchmarking purposes, the algorithm performance is compared with Particle Swarm Optimization (PSO) under identical simulation settings. Results show that QHBM achieves higher power extraction performance, with an average improvement of 15.90% at a representative wind speed of 10 m/s. Statistical evaluation across 30 simulation runs indicates that QHBM also exhibits greater robustness, with significantly lower output variability. Furthermore, the algorithm achieves MPPT tracking efficiency of up to 96.80% under dynamic wind conditions. These results demonstrate that the migration-based search mechanism of QHBM enhances the ability to maintain optimal turbine operating conditions, leading to improved energy yield and operational stability for wind power systems in island environments.

Abstract

Tukad Sumaga tangerine (Citrus reticulata) is a local citrus cultivar with potential as a horticultural genetic resource; however, its morphological characteristics and volatile chemical profile require systematic documentation. This study aimed to characterize the morphological traits and fruit quality of Tukad Sumaga tangerine and identify volatile compounds in its leaf extract using gas chromatography–mass spectrometry (GC-MS). Morphological characterization was conducted based on citrus descriptors, covering roots, stems, branching patterns, leaves, flowers, fruits, and seeds. Fruit quality was assessed based on total soluble solids (TSS), while leaf samples were extracted using 70% ethanol through maceration and analyzed by GC-MS. The plants exhibited a woody taproot system, upright cylindrical stem, sympodial branching with a spreading habit, ovate to elliptic glabrous leaves, actinomorphic white flowers, and ovoid to pyriform fruits with relatively rough peel surfaces. Fruit TSS reached 16 °Brix, with three to five seeds per fruit. GC-MS identified 15 compounds with similarity indices of 95–99%, including 3-hexanone, 2-hexanone, 3-hexanol, 2-hexanol, linalool, bicycloelemene, β-elemene, trans-β-caryophyllene, germacrene-D, and bicyclogermacrene. These findings provide baseline information for identification, conservation, and further investigation of Tukad Sumaga tangerine as a local citrus genetic resource

Abstract

The poultry feed industry in Belu Regency faces the challenge of seasonal corn availability, which has the potential to disrupt production continuity. This research aims to design an optimal corn procurement system thru a dynamic system modelling approach. The methodology includes stakeholder data collection, the creation of Causal Loop Diagrams and Stock and Flow Diagrams using Vensim PLE, as well as model validation thru MAPE testing, face validation, and sensitivity analysis. The verified model was then simulated in three procurement scenarios: involving farmers and distributors, the implementation of the Government Purchase Price (HPP) with BUMDES/Cooperative institutions, and mass procurement each harvest season. The simulation results show that the HPP Scenario yields the lowest total cost of Rp25.74 billion, stabilizes prices and supply, and minimizes the risk of overstock and raw material damage. In contrast, the bulk procurement scenario carries a high risk of excessive storage costs, while the basic model results in more expensive fluctuating costs. In conclusion, the intervention of government benchmark pricing policies and the strengthening of local storage institutions are the most effective strategies to balance industrial supply and demand. This scenario is recommended as a strategic blueprint to ensure production sustainability and operational cost efficiency
