Abstract

The purpose of this study is to systematically identify and analyze global research trends in early childhood science education for children aged 3-8 years, focusing on prevalent instructional approaches and their effectiveness. A systematic literature review was conducted following the PRISMA guidelines. The Scopus database was queried for relevant, accredited articles published between 2015 and 2025. After applying strict inclusion criteria, a final corpus of seven key publications was selected for in-depth qualitative analysis to identify dominant themes and patterns. This review provides a synthesized analysis of the most recent and impactful pedagogical strategies in early childhood science education. It confirms the dominance of concrete, experience-based learning and reveals the significant effectiveness of role-playing and multimodal visualization techniques in making abstract scientific concepts accessible to young learners. A key novel insight is the identification of critical contextual factors for successful implementation, highlighting that teacher acceptance of new methodologies is highest when they align with existing pedagogical values and daily practices. Furthermore, the study underscores the influential role of the teacher and the intentional design of the learning environment in fostering scientific engagement. The primary contribution is a clear, evidence-based argument for developing holistic, play-based, and contextually relevant curricula. These findings offer a foundational framework for educators, researchers, and policymakers to design effective, developmentally appropriate, and engaging science learning strategies for the modern era.

Abstract

Digital literacy has become an essential competency for students in the 21st century, particularly in science learning that integrates technology and contextual learning resources. However, appropriate assessment instruments to measure students’ digital literacy skills are still limited. This study aimed to develop a valid and reliable instrument for assessing junior high school students’ digital literacy skills using Zep Quiz media in the context of ecoprint batik learning. The research employed a Research and Development (R&D) method using the Borg and Gall model, which was modified into several stages: problem analysis, planning, product design, expert validation, product revision, small-scale testing, operational revision, and large-scale testing. The participants of this study were 125 junior high school students. Data were collected through observation, questionnaires, and digital literacy assessment tests. The results of expert validation indicated that the developed instrument was highly valid. Item validity analysis showed that all test items met the validity criteria. Furthermore, the reliability coefficient of the multiple-choice test in the large-scale trial reached 0.762, which is categorized as high reliability. These findings indicate that the developed instrument is valid, reliable, and feasible to measure students’ digital literacy skills in science learning using Zep Quiz media integrated with ecoprint batik materials.

Abstract

Mangrove ecosystems are important habitats for various benthic organisms, including bivalves, which play a role in maintaining the ecological balance of aquatic environments. The Jenggalu Mangrove Forest Tourism Park in Bengkulu City has high potential for biodiversity, but information on the structure of the bivalve community in this area is still limited. This study aims to determine the structure of the bivalve community, including species composition, abundance, and environmental conditions that influence their existence in the Jenggalu mangrove ecosystem. The study was conducted using a survey method with direct sampling techniques at several observation points in the mangrove area. Each bivalve individual found was then identified based on morphological characteristics, counted, and analysed for community structure using ecological indices such as diversity, evenness, and dominance. The results showed that the bivalve community in the Jenggalu mangrove area consisted of several species with different abundance levels at each observation location. The diversity index value was in the moderate category, indicating that environmental conditions were still sufficiently supportive of bivalve life. The relatively stable evenness value indicated a fairly even distribution of individuals between species, while the low dominance value indicated that no species was overly dominant. The results of this study indicate that the mangrove ecosystem in this area still has environmental conditions that are sufficient to support bivalve life. This information is expected to form the basis for efforts to manage and conserve the mangrove ecosystem and preserve the diversity of aquatic biota in the area.

Abstract

This study aims to analyze the morphometric characteristics of Anura found in Rajolelo Forest Park, Central Bengkulu. Data collection was conducted from November 2025 to January 2026 using the Visual Encounter Survey (VES) method in two habitat types, namely secondary forest and lakeshore. Each individual found was identified and measured using 13 morphometric characters with the help of a caliper. The results showed that the Anura community found consisted of three families, namely Dicroglossidae, Ranidae, and Rhacophoridae, with five species and a total of 20 individuals. Morphometric analysis showed that there were variations in body size and limb proportions between species related to habitat differences. Species found in water tend to have larger body sizes, while species living in vegetation or secondary forests have longer limbs that support the ability to jump and move in vegetation. Thus, morphometric variations in Anura indicate morphological adaptations to different habitat conditions.

Abstract

The present study reports the design, development, and evaluation of DeepCrit, a deep learning (DL)–driven intelligent tutoring system (ITS) intended to enhance students’ critical action skills in science education. While ITS research has expanded rapidly alongside advances in adaptive learning and learner modeling, few systems explicitly target higher-order skills such as critical action—a dimension of critical consciousness involving the capability to analyze socio-scientific issues, design evidence-based solutions, and enact transformative actions. This study addresses this gap through a multiphase mixed-method evaluation integrated with Design-Based Research (DBR). The research involved preliminary needs analysis, conceptual design, prototype development, expert validation, and classroom implementation with 62 secondary school students. DeepCrit integrates deep knowledge tracing, multi-task learner profiling, a knowledge graph–based domain model, and a pedagogical engine driven by a deep Q-network to provide adaptive and dialogic scaffolding around socio-scientific issues. Quantitative results demonstrate significant improvements in critical reflection, critical motivation, and critical action, alongside gains in conceptual science mastery. Qualitative findings reveal that DeepCrit supports students’ movement through praxis cycles—reflection, decision-making, and action—thereby strengthening their scientific agency. This study contributes a pedagogical and technical framework for designing ITS that support transformative science learning aligned with the demands of the 21st century.

Abstract

This research is motivated by the need for contextual learning media that is able to increase the reading interest and science literacy of elementary school students in the material of the human digestive system. The research aims to analyze the need for the development of Big Books with ethnoscience content as the basis for designing learning media that is relevant to local culture. The research is a preliminary study with a mixed descriptive approach (qualitative and quantitative). The research was carried out in Muruk Rian District, Tana Tidung Regency, North Kalimantan, namely SDN 004, SDN 005, SDN 016, and SDN 024 Tana Tidung, involving 27 students and 4 teachers. Data were collected through observation, science literacy cognitive tests, closed questionnaires, and interviews. The results showed that students' reading interest was relatively high, but there were emotional barriers and uneven reading experiences. The attitude of students' science literacy is positive, but epistemic understanding and involvement in environmental issues is still limited. Students' science literacy skills are in the sufficient category, while procedural skills and scientific inquiry design are relatively low. Teachers and students expressed a high need for contextual and easy-to-understand visual media. These findings confirm the potential of the Big Book containing ethnoscience as a relevant medium to relate science concepts to local culture and become the basis for development and effectiveness testing at the next stage of research.

Abstract

Tissue culture propagation of Kappaphycus alvarezii Maumere variety at SEAMEO BIOTROP Bogor produced planlets exhibiting an unusual color shift from the original brown (LC) to green (LH) at a mutation ratio of 1:50 within culture bottles. This study aimed to characterize the molecular identity and genetic relationships of these color-variant planlets using the Internal Transcribed Spacer (ITS) DNA barcoding marker and phylogenetic reconstruction in MEGA X. DNA sequencing using ITS primers revealed that both color variants (LH and LC) confirmed as K. alvarezii based on NCBI BLAST analysis (Query Cover: 92%; Percent Identity: 87.52%; Accession No. JN673973.1). The nucleotide compositions showed T(U): 23.84%, C: 22.48%, A: 25.48%, G: 28.20% (LH) and T(U): 25.28%, C: 26.40%, A: 25.42%, G: 22.89% (LC), with total nucleotide lengths of 734 and 712 bp, respectively. No single nucleotide polymorphism (SNP) was associated with the color characteristic detected between the two variants. Genetic distance analysis indicated a close relationship between LH and LC (distance: 0.155), while both showed considerable divergence from the reference K. alvarezii KC905270.1 (0.626 and 0.629, respectively) and from Eucheuma isiforme (0.565 and 0.563). The phylogenetic tree confirmed that LH and LC belong to the same species with a distinct color phenotype potentially attributable to epigenetic or physiological factors. These findings provide molecular baseline data for the utilization of tissue-culture-derived K. alvarezii Maumere variety in seaweed aquaculture programs in Indonesia.

Abstract

Indonesia's high disaster vulnerability significantly impacts elementary school students' physical and psychosocial well-being. Post-disaster, children often experience declines in physical fitness, fundamental movement skills, anxiety, and social interaction—directly affecting their learning readiness. This study aimed to develop and examine the effectiveness of a Deep Learning Pedagogical and Ecopedagogy-Based Fundamental Movement Learning Model (DL-Eco Model) as a holistic recovery intervention for post-disaster elementary school students. Employing a Research and Development (R&D) design with the ADDIE framework, the model was developed through systematic analysis, design, development, implementation, and evaluation stages. Effectiveness was tested using a quasi-experimental nonequivalent control group design across four elementary schools in one disaster-affected province (n ≈ 120 students, grades IV–V). Instruments included the Fundamental Movement Skills (FMS) test, the Indonesian Physical Fitness Test (TKJI), the Child Resilience Scale, and the Psychosocial Well-being Scale. Content validity was established using Aiken's V (≥ 0.80), and data were analyzed through descriptive and inferential statistics (independent t-test, ANCOVA, Cohen's d, and N-Gain). The DL-Eco Model integrates four instructional phases: experience orientation, movement exploration, meaningful reflection, and ecological action. This integration simultaneously addresses motor competence, reflective learning, social development, and ecological awareness—filling a conceptual and methodological gap in disaster-responsive physical education. The model is expected to contribute to the advancement of disaster-responsive pedagogy and broaden Physical Education's role as a school-based holistic recovery instrument.

Abstract

Piper retrofractum (Javanese long pepper) is an economically important medicinal plant valued for its piperine content. However, its productivity and quality remain inconsistent under tropical agroecosystems due to suboptimal nutrient management and light conditions. This study aimed to evaluate the interactive effects of fertilizer types and shading levels on growth, yield, and piperine content, as well as to determine the relationships among these variables. A factorial completely randomized design was employed with two factors: fertilizer types (NPK, biofertilizer, local microbial liquid organic fertilizer, and a combination of NPK and biofertilizer) and shading levels (0%, 40%, and 60%), resulting in 12 treatment combinations with three replications. The observed parameters included number of productive branches, dry fruit weight per plant, and piperine content. Data were analyzed using ANOVA, followed by DMRT at 5%, and strengthened with Pearson correlation and multiple regression analyses. The results showed that the combination of NPK and biofertilizer under no shading significantly produced the highest values for all parameters. Productive branches exhibited a very strong positive correlation with dry fruit weight (r = 0.88**) and moderate correlation with piperine content (r = 0.61*), while dry fruit weight showed a strong correlation with piperine content (r = 0.69**). The regression model (R² = 0.88) indicated that both productive branches and dry fruit weight significantly contributed to piperine content, with dry fruit weight having a greater influence. These findings highlight that optimizing fertilization strategies and light conditions can simultaneously enhance yield and bioactive compound accumulation in P. retrofractum under tropical conditions.

Abstract

Coastal settlements along the northern coast of Java face escalating environmental pressures due to tidal flooding, land subsidence, and sea level rise. While sea wall development has been widely implemented as a macro-scale mitigation strategy, it remains insufficient in addressing vulnerabilities at the settlement level, particularly within informal fishing communities. This study examines adaptive housing as an alternative strategy for coastal settlement planning and evaluates its contribution to regional resilience and national defence. An embedded mixed-method approach was employed, combining qualitative analysis with quantitative data collected from 100 respondents in Muara Angke, North Jakarta. The findings reveal that adaptive housing through elevated and floating structures significantly reduces structural damage, lowers flood exposure, and improves access to clean water and sanitation. Community participation also increased substantially, indicating strengthened social resilience. In addition, the use of modular construction enhances efficiency in both time and cost. This study proposes the Integrated Coastal Settlement Resilience Model (ICSRM), which integrates macro-level infrastructure, micro-level adaptive housing, and community capacity as a unified resilience framework. The results demonstrate that adaptive housing not only improves environmental and socio-economic conditions but also contributes to territorial resilience within the broader context of non-military national defence. The study highlights the importance of multi-scalar integration in achieving sustainable coastal resilience.
