Abstract

This study aims to determine the argumentation skills of grade 10th students towards socio-scientific issues at one of the senior high schools in Cileungsi, Bogor. This study was conducted using test and documentation techniques. The research method used is quantitative descriptive. Sampling was carried out using a purposive sampling technique; there are 128 students from 4 classes. The instruments used in this study were 5 standpoint questions related to the phenomenon of the spread of monkey pox and the test scores for virus material. The results of the study revealed that the quality of the written argumentation skills of class X students was mostly at levels 2 and 3, with an average percentage of 30.30% and 45.62% respectively. The findings imply that students are still in the process of developing higher-order thinking and scientific reasoning skills when engaging with socio-scientific issues. Therefore, science educators are encouraged to incorporate explicit argumentation-based learning strategies to promote deeper analysis, evidence-based reasoning, and the ability to construct coherent scientific arguments in response to real-world problems.

Abstract

Data literacy is an essential aspect in science and education, yet its integration in biology education remains underexplored. Competence in data literacy is essential for biology education students to conduct learning evaluation analyses that increase student learning performance. Grounded in Bandura’s social cognitive theory, this study investigates biology education undergraduates’ self-efficacy in data literacy during a statistics course. A convenience sample of 70 students completed a questionnaire assessing confidence (7 items), experience (4 items), and attitude (4 items) of data on a 5-point Likert scale. Additionally, students completed a data interpretation test (with biology-based data scenarios), rated their confidence on a 4-point Likert scale, and provided reasoning. Result revealed high levels of self-efficacy across all domains, consistent confidence during data interpretation tasks, and positive attitudes towards learning with data. The study contributes conceptually by linking perceived confidence and performance-based evidence of data literacy, highlighting implications for improving quantitative reasoning in biology education

Abstract

The global environmental crisis is not just a warning, but a call to action, and education is key. NSA Surabaya High School addresses this challenge through the unique learning innovation of kokedama, a Japanese art of farming that combines aesthetics and sustainability. More than just the practice of planting, kokedama is a powerful medium to instill ecological awareness in the younger generation. With a hands-on method combined with affective reflection, students not only learn farming skills, but also develop a deep empathy for nature and a real sense of ecological responsibility. This finding proves that contextual education can be a concrete solution to instill environmental awareness, solution to instill environmental awareness from an early age. We recommend this activity as a revolutionary strategy to create a generation of high school students who not only care but are also ready to lead the change for the sustainability of our planet.

Abstract

Metro City (Lampung, Indonesia) contains five urban forests, including Linara and Tejosari, whose fern (ferns and lycophytes) diversity has not been comprehensively documented. This study inventoried fern species composition, abundance, conservation status, and general ecological roles in both urban forests using a systematic plot approach (four 5 × 5 m plots per site; 100 m² per site). All individuals within plots were recorded and counted; taxa were identified using vegetative characters supported by field photographs, and scientific names were standardized using Plants of the World Online (POWO). Diversity was quantified using the Shannon–Wiener index (H’), and conservation status was checked using the IUCN Red List. A total of 48 species were recorded across both sites; Linara showed higher diversity (H’ = 3.23; high category) than Tejosari (H’ = 2.65; moderate category). The most abundant species differed between sites, with Drymoglossum piloselloides dominating Linara (564 individuals) and Cystopteris fragilis being most frequent in Tejosari (32 individuals). Taxonomically, species richness was concentrated in a few families, especially Polypodiaceae (16 species), while other families contributed fewer species. Differences between sites are indicate that the two locations provide different microhabitat conditions, particularly regarding the availability of shaded and humid areas that support the existence of ferns. The findings of the dominance fern family and differences in the most abundant species in each location confirm that variations in habitat structure and levels of disturbance in urban green spaces have the potential to shape local fern communities. Therefore, urban forest management needs to prioritize the maintenance of key microhabitats and habitat continuity to maintain fern diversity.

Abstract

The demands of 21st-century education require students not only to master conceptual knowledge but also to develop essential skills such as collaboration and problem-solving. These skills are particularly important in biology learning, which often emphasizes real-world applications and teamwork. This study aims to determine the effect of the Bio-entrepreneurship-based Project-Based Learning (PJBL) model on students' collaborative problem-solving (CPS) skills. This study was conducted at a public high school in Tasikmalaya City in the even semester of the 2024/2025 academic year using a quasi-experimental method and a matching-only post-test control group design. The population consisted of 432 tenth-grade students from 12 classes, with samples selected through purposive sampling: class XE-9 as the experimental group and class XE-12 as the control group. Data were collected using an 18-item CPS questionnaire on a 1–4 Likert scale. The results showed that the experimental class achieved a higher mean CPS score (M = 3.01) compared to the control class (M = 2.80). Based on the independent sample t-test, the significance value was 0.043 (p < 0.05), indicating that the Bio-entrepreneurship-based PJBL model had a significant effect on students’ collaborative problem-solving skills in biotechnology learning. These findings imply that integrating entrepreneurial contexts into biology instruction can effectively enhance students’ 21st-century skills, particularly collaborative problem-solving

Abstract

The Flores Sea in eastern Indonesia is a marine biodiversity hotspot within the Wallacea region, yet its bacterial community remains largely unexplored. This study aimed to characterize bacterial diversity in Flores Sea surface water by re-analyzing publicly available metagenomic data. Public shotgun metagenomic data was obtained from the NCBI Sequence Read Archive (SRA) under accession number SRR37631993 (Bioproject: PRJNA1437532), comprising 40,285,030 paired-end reads (2×150 bp) generated using the MGI DNBSEQ G50 platform. Quality trimming was performed using fastp v1.1.0. Taxonomic classification was conducted using Kraken2 v2.1.3 against the standard database (k2_standard_08gb_20230605), followed by species-level abundance estimation with Bracken. Diversity indices (Shannon, Simpson) were calculated based on relative abundance. The results showed that 13,041,976 reads (64.8% of total) were successfully classified, identifying 4,477 bacterial species with significant abundance. The Shannon diversity index (H') was 3.95, indicating very high diversity. The Simpson index (1-D) was 0.94, demonstrating high community evenness. The bacterial community was dominated by halophilic bacteria, with Halomonas meridiana as the most abundant species (19.7%), followed by Chromohalobacter salexigens (5.1%) and Idiomarina loihiensis (4.9%). The dominance of halophilic bacteria reflects adaptation to the marine environment. These findings provide the first baseline data on bacterial diversity in Flores Sea surface water based on a single public metagenomic sample, establishing a foundation for future microbial monitoring in the understudied Wallacea region.

Abstract

Integrating Education for Sustainable Development (ESD) into teacher education requires shifting from theoretical knowledge to practical action competence. This study aims to describe how an Ethnobotanical Inventory Project empowers pre-service biology teachers to navigate the complexities of community-based conservation. Employing a qualitative case study design, the research focuses on three student working groups at UIN Siber Syekh Nurjati Cirebon who investigated distinct cultural sites: the Mundu coastal area, the Buyut Trusmi sacred site, and the Singkup agrarian village. Data were collected through field observations, semi-structured interviews, and analysis of student artifacts. The results demonstrate that the project successfully cultivated sustainability agency. Students developed interpersonal competence by negotiating access with traditional custodians (Paraji and Kuncen) and demonstrated scientific literacy by validating local knowledge with botanical taxonomy in their dissemination products (Pocket Books). Furthermore, the inventory highlighted a dichotomy in plant conservation: "Cultural Keystone Species" driven by ritual needs in Mundu and Trusmi (e.g., Jasminum sambac), versus pharmacologically validated medicinal plants in Singkup (e.g., Curcuma xanthorrhiza). It is concluded that incorporating local wisdom into biology learning serves as a strategic pedagogical tool to foster future teachers who are scientifically literate, culturally sensitive, and capable of leading sustainability actions.

Abstract

Climate change is an ongoing critical issue that has impacted all countries globally, including Indonesia. The major problem in environmental learning is how affected society can adapt and mitigate climate change. The public can quickly obtain information regarding climate change, but educational information on methods to adapt and mitigate climate change still needs to be improved. Students are crucial in assisting the government in educating the public on methods of adapting to and mitigating climate change. In response to rapid technological advancements, Electronic Information of Adaptation and Mitigation (EI-AME) was developed as an interactive digital learning module to support environmental education. This study aims to examine the improvement of students’ communication skills in climate change education through the implementation of EI-AME. The experimental method was used in this research, with a sample of 146 students from two universities in Jakarta, Indonesia. This research's design is a pretest-posttest with a control class. The instrument used consisted of 14 essay questions with 4 different aspects of communication skills. The research outcome revealed that students' communication skills scores significantly increased in the experimental class compared to the control class. This shows that EI-AME can be an innovative teaching material in the future for strengthening students' communication skills. Further research should be conducted to highlight how such communication skills can help students transfer information in society.

Abstract

The increasing ability of bacteria to develop resistance to antibiotics highlights the urgent need for alternative antibacterial agents that are safe, affordable, and environmentally friendly. One promising option is eco-enzymes produced through the fermentation of fruit peel waste. This study aimed to compare the antibacterial activity of eco-enzymes derived from pineapple peel (Ananas comosus), dragon fruit peel (Hylocereus polyrhizus), and a mixture of both against Escherichia coli and Staphylococcus aureus. An experimental study was conducted using a post-test only control group design. The eco-enzymes were anaerobically fermented for three months and subsequently evaluated for antibacterial activity using the Kirby–Bauer disc diffusion method on Nutrient Agar (NA), with bacterial cultures prepared in Nutrient Broth (NB). Each treatment was performed in triplicate, and inhibition zone diameters were analyzed using quantitative descriptive analysis. The results showed that pineapple peel eco-enzyme produced the largest inhibition zones against S. aureus (12.5 mm) and E. coli (9.6 mm), which were classified as moderate to strong antibacterial activity according to Clinical and Laboratory Standards Institute (CLSI) criteria. In contrast, dragon fruit peel eco-enzyme exhibited no inhibitory effect on either bacterium, while the mixed eco-enzyme demonstrated weak to moderate inhibition against S. aureus (6.6 mm) and E. coli (3.7 mm). Overall, pineapple peel eco-enzyme displayed the highest antibacterial effectiveness and shows potential for development as a natural antibacterial agent derived from organic waste.

Abstract

The Penunggul mangrove ecosystem has undergone continued rehabilitation, but the extent to which recent spatial changes reflect changes in aboveground carbon remains unclear. This study evaluated changes in mangrove extent and canopy-density classes between 2021 and 2025, estimated aboveground carbon stock (AGC) using the InVEST model and field-based allometry, and examined the relationships of NDVI and field-measured canopy cover with plot-level AGC. Sentinel-2 imagery was classified using a Random Forest algorithm, while vegetation structure and canopy cover were measured in ten field plots. Mangrove area increased from 18.94 ha in 2021 to 19.95 ha in 2025 (an increase of about 1.01 ha, or 5.33%), accompanied by an expansion of the high-density canopy class from 16.62 to 18.37 ha. The classification produced apparent Overall Accuracy and Kappa coefficients of 1.00 in the validation dataset. Field measurements recorded tree and sapling densities of 3,460 and 1,100 individuals ha⁻¹, respectively, with Rhizophora mucronata as the dominant taxon. Field-derived AGC was 71.92 Mg C ha⁻¹, whereas the 2025 InVEST estimate reached 280.10 Mg C ha⁻¹, indicating substantial overestimation by the class-based model. NDVI showed virtually no relationship with field-derived AGC, while canopy cover exhibited a positive linear association that was not supported by the Spearman correlation and should therefore be interpreted cautiously. These findings indicate that Sentinel-2 and InVEST are useful for assessing broad spatial patterns, but field measurements and spatially matched validation remain necessary for reliable local carbon estimation.
