Abstract

Soil-borne fungal pathogens represent a persistent threat to plant health due to their ability to colonize the rhizosphere and infect root systems, yet information on their diversity in non-industrial palm species remains limited. Siwalan (Borassus flabellifer L.) is a drought-tolerant palm of ecological and socio-economic importance, but its rhizospheric fungal communities have not been systematically characterized. This study aimed to (1) isolate soil-borne fungi from the rhizosphere of siwalan and (2) identify potential pathogenic fungi based on macroscopic and microscopic morphological characteristics. Rhizosphere soil samples were collected at depths of 5–20 cm and processed using the soil dilution plate method. Fungal isolates were cultured on potato dextrose agar (PDA), purified through subculturing, and identified using colony morphology and microscopic structures observed through slide culture and lactophenol cotton blue staining. Data were analyzed descriptively by comparing fungal traits with standard taxonomic determination keys. Five soil-borne fungal taxa were successfully isolated and identified, namely Aspergillus flavus, Trichoderma longibrachiatum, Aspergillus oryzae, Aspergillus caelatus, and Aspergillus niger. The isolates exhibited distinct differences in colony pigmentation, growth rate, hyphal structure, vesicle morphology, and conidial characteristics. Among them, A. niger showed the fastest radial growth and highest sporulation intensity, whereas T. longibrachiatum and A. oryzae exhibited relatively slower growth. These morphological variations indicate functional diversity and differing adaptive strategies among fungi inhabiting the siwalan rhizosphere. This study provides the first systematic morphological baseline of soil-borne fungi associated with the rhizosphere of B. flabellifer. The findings contribute novel information on fungal diversity in an underexplored palm species and highlight the importance of early fungal characterization as a foundation for future molecular identification, pathogenicity testing, and the development of sustainable disease management strategies for siwalan cultivation systems.

Abstract

Foodborne diseases pose a critical global health threat, exacerbated by the alarming rise of multidrug-resistant (MDR) bacterial strains like Staphylococcus aureus, Escherichia coli, and Salmonella typhi. Conventional antibiotics are increasingly ineffective, necessitating the development of alternative therapeutic and biocontrol strategies. This study aims to evaluate the efficacy and stability of a bacteriophage cocktail as a potential non-antibiotic alternative for controlling a consortium of foodborne pathogenic bacteria. The research employed an experimental design using revived cultures of the three bacterial species and three phage isolates (ϕSZUT-01, ϕSZIP-01, ϕSZIP-02) as research samples. Data collected included bacterial growth kinetics, observation of lysis zones, and phage stability at various pH levels and storage temperatures. Data analysis was conducted descriptively, followed by one-way ANOVA at a 95% confidence level to determine differences among treatments. Three two-phage cocktails were formulated and tested, with all treatments consistently demonstrating strong lytic activity, evidenced by large and clear plaques. Lysis kinetics, monitored through OD600 measurements, confirmed rapid bacterial elimination beginning approximately 180 minutes post-infection. Notably, the bacterial consortium exhibited resistance to the positive control (Chloramphenicol), reinforcing the need for alternative interventions. Additionally, the phage cocktail demonstrated excellent stability, maintaining infectious titers across a broad pH range and during storage at both refrigerated (4°C) and room temperatures (21°C). This high stability supports its potential applicability in food safety systems and resilience in gastrointestinal environments. Overall, the bacteriophage cocktail demonstrated effective antibacterial activity against a consortium of foodborne pathogenic bacteria, as evidenced by the formation of clear lysis zones and exhibited high stability, supporting its potential application as a non-antibiotic alternative for controlling foodborne diseases.

Abstract

Breast cancer, particularly the estrogen receptor-positive (ER-positive) subtype, remains a significant global health challenge. Although Aerva sanguinolenta (AS) has shown Anti-cancer potential, its comprehensive mechanistic effects on breast cancer are still largely unknown. This study aims to uncover the pharmacological effects of AS bioactive compounds on breast cancer using an integrated network pharmacology and molecular docking approach. Bioactive compounds in AS were identified through GC-MS. Compound-target and breast cancer gene interactions were obtained from various databases, followed by protein-protein interaction, Gene Ontology, and KEGG pathway analyses. Molecular docking studies were then used to confirm key interactions. We found that 4 of 103 AS compounds met strict screening criteria, identifying 712 potential gene targets, 33 of which were directly related to breast cancer, including hormonal (ESR1) and apoptosis (AURKA) pathways. Further analysis and molecular docking confirmed the strong binding affinity of Bakuchiol and Afzelin compounds to their main targets, which are involved in critical biological processes such as estrogen receptor signaling, cell cycle regulation, and pathways related to cell proliferation and breast cancer development. In conclusion, this study provides a comprehensive understanding of the potential mechanisms of AS bioactive compounds Afzelin and Bakuchiol against breast cancer, demonstrating their therapeutic potential through Network Pharmacology and docking scores.

Abstract

Ipomoea reptans is a widely consumed vegetable in Indonesia, but it is known as a hyperaccumulator of mercury, posing a risk to human health. The use of arbuscular mycorrhizal (AM) fungi has the potential to inhibit mercury translocation from roots to shoots, although comparative studies among AM fungal species remain limited.  The study aimed to evaluate various types of AM fungi that have the potential to inhibit mercury translocation in shoot tissues and to analyze the effect of AM fungi on the growth of I. reptans in mercury-contaminated soil. The type of research is experimental research. I.  reptans was either uninoculated or inoculated with Acaulospora tuberculata, Glomus sp., mixed inoculum among Acaulospora, Glomus, Gigaspora, and Scutelospora and then grown in soil with mercury contamination of 0, 4, and 8 mg Hg/kg dry soil. Plants were harvested 35 days after showing, and the phosphorus and mercury content in the shoot were determined using a UV-Vis spectrophotometer and AAS, respectively. Plant growth data and phosphorus content in the shoot were analyzed using two-way ANOVA. The results showed that AM fungi application enhanced plant growth by increasing shoot dry weight and leaf area. Inoculation with A. tuberculata and Glomus sp. reduced mercury concentration in shoots, with the lowest level observed under A. tuberculate alone, while mixed inoculum increased mercury uptake. Overall, A. tuberculata showed strong potential as an amelioration agent for sustainable agriculture on heavy metal-contaminated soil, although further molecular and field studies are necessary.

Abstract

Learning that integrates the green/blue economy through the ASICC model has improved students' critical thinking skills. However, there was currently no scientific explanation for this case. Therefore, this study was aimed to reveal how the ASICC learning model can improve students' critical thinking skills. The case study was conducted in a class that implementing the ASICC learning model. Data of critical thinking skills was collected using a critical thinking test instrument integrated with essay test questions for conceptual understanding. Learning activity scores at each stage of the ASICC model are assessed using a rubric that has been developed. Multiple regression analysis was used to obtain contribution scores for each stage of student learning activities. This study revealed that the interpretation stage has the highest influence or contribution compared to other stages, namely reaching 51.71% towards increasing students' critical thinking scores. In order to improve students' critical thinking scores through the ASICC model integrated with green/blue economy issues, teachers should allocate sufficient time to students at the interpretation stage.

Abstract

Understanding the concept and hands-on skills in microbiology is crucial for science teachers because they help students develop critical thinking and retain information. This study aimed to develop a team-based project worksheet using a kitchen microbiology approach to improve students’ concept understanding and hands-on skills in identifying fungi from orange peels (Citrus spp.). The research employed a modified Borg and Gall R&D method to develop the worksheet (planning, product development, limited trials, and product revision). A limited trial was conducted to assess the students’ performance in a small-scale study involving 9 students selected from the Science Education Undergraduate Study Program at Universitas Negeri Semarang, using a one-group pretest-posttest design. The worksheet was validated, and all data were analyzed quantitatively. The results of worksheet validation by media and content experts indicated the worksheet is highly feasible (average >93%). Results showed a significant improvement in concept understanding and hands-on skills, with an N-Gain of 0.71. In conclusion, the kitchen microbiology-based worksheet effectively enhanced students’ concept understanding and hands-on skills while requiring further refinement. Its novelty lies in the use of everyday kitchen materials as educational media, the integration of teamwork and scientific communication, and the interdisciplinary blend of microbiology and sustainability, positioning it as a promising contextual learning model with both practical and social impact.

Abstract

Traditional medicinal and personal care plant use remains an important component of community health practices in rural Indonesia, yet integrated quantitative ethnobotanical documentation is still limited. This study aimed to identify plant species used for medicinal and cosmetic purposes, document their parts and preparation methods, and analyze their cultural importance using quantitative ethnobotanical indices. A qualitative descriptive ethnobotanical design was applied through semi-structured interviews and participatory field observations involving 30 informants across 20 sites in Talun and Doko, Blitar. Data were analyzed using Use Value (UV) and Informant Consensus Factor (ICF) to evaluate species importance and agreement levels among informants. A total of 25 plant species from 19 families were recorded, with leaves as the most frequently utilized plant part and internal medicine as the dominant use category. The highest UV values were found in Peperomia pellucida (0.87) and Physalis angulata (0.80). The highest consensus occurred in eye care (ICF = 1.00), followed by internal medicine and skin treatment (ICF = 0.83). These results indicate strong cultural reliance and shared knowledge patterns in local plant use. The findings provide quantitative support for prioritizing culturally important species and offer applied potential for biodiversity conservation and contextual biology education.
