Abstract

This literature review explores the multifaceted role of Pseudomonas syringae, a bacterium renowned for its ice-nucleating properties. Pseudomonas syringae significantly influences atmospheric processes, agriculture, and various ecosystems. These bacteria, equipped with ice nucleation proteins (INPs), facilitate ice formation at temperatures warmer than the typical freezing point, impacting weather patterns by initiating snow and hail formation. While its ice-nucleating activity can lead to frost damage in agriculture, it is also harnessed for artificial snow production. This review synthesizes findings on the bacterium's characteristics, morphology, physiology, and ecology, drawing from diverse studies. It highlights its widespread presence in various environments, including plant surfaces, water bodies, and atmospheric samples, emphasizing its adaptability and ecological significance. By employing content analysis on secondary data sources, this study provides a comprehensive understanding of Pseudomonas syringae's unique ability to mediate ice formation and its broader implications for environmental balance and biotechnological applications.Keywords:  INA bacteria, Pseudomonas syringae, ice formation, InaZ  protein

Abstract

There are several main indicators that can be used to assess the quality of sourdough starter, namely pH, dough volume, and the presence and diversity of Lactic Acid Bacteria (LAB). Meanwhile, the addition of natural ingredients such as fermented Ambon bananas is considered to be able to improve the quality of sourdough starters, by increasing the number and diversity of LAB. This study is a comparative exploratory study that compares the quality of sourdough starters made with fermented Ambon bananas (Type III) and those made without Ambon bananas (Type I), and identifies the diversity of LAB in both. This study showed that all parameters are better in type III than in type I, where the pH is lower, the dough develops faster and has a larger volume, and the number of LAB is higher. Meanwhile, the LAB contained in Type III is more diverse (Lactobacillus pentosus, Lactobacillus plantarum, and Lactobacillus paraplantarum) compared to Type I, which only contains one isolate (Lactobacillus pentosus). Based on the results found, sourdough with the addition of Ambon banana fermentation can produce better starter quality and contains more diverse LAB, namely heterofermentative and homofermentative.Keywords: sourdough starter, fermented ambon banana fruit, lactic acid bacteria.

Abstract

This study aims to examine the alignment between the planning and implementation of biology learning based on the 2013 Curriculum in public high schools in Biringkanaya District, Makassar City, with a focus on the integration of 4C skills and Higher-Order Thinking Skills (HOTS). This study uses mixed methods involving four 11th grade biology teachers. Data were collected through analysis of lesson plans, observation of classroom teaching, and teacher questionnaires, then analyzed descriptively and inferentially using the chi-square test. The results showed that the quality of lesson plan preparation and biology teaching implementation was generally very low, especially in the formulation of Competency Achievement Indicators and learning objectives, which were still dominated by low-level thinking skills (C1–C2). The observation results also revealed limitations in the use of authentic stimuli, HOTS questions, and meaningful discussions, so that the development of students' 4C and HOTS skills was not optimal. The chi-square test showed a significant relationship between teachers' ability to design lesson plans and the quality of classroom teaching. These results emphasize the importance of strengthening teachers' pedagogical competencies in designing and implementing biology learning that is aligned with and oriented towards 21st-century skills.Keywords: lesson plans, learning implementation, biology.

Abstract

The growing crisis of antimicrobial resistance has intensified the search for new antibacterial agents, and the diverse tropical flora of Lampung offers a promising natural reservoir of bioactive compounds. This review synthesizes current evidence on plant and algal phytochemicals from Lampung that have been evaluated against two clinically important pathogens, Escherichia coli and Staphylococcus aureus. Following the PRISMA 2020 guidelines, a systematic search conducted on 31 July 2025 using Harzing’s Publish or Perish and databases such as Google Scholar and PubMed identified 200 records. After screening and eligibility assessment, 20 studies published between 2015 and 2025 were included in the analysis. Most investigations employed disc diffusion and minimum inhibitory concentration assays and consistently reported antibacterial activity, with stronger effects generally observed against S. aureus. The predominant classes of active compounds included flavonoids, alkaloids, tannins, saponins, and essential oils. Several species, such as Anredera cordifolia, Mangifera indica peels, Citrus aurantifolia, Syzygium polyanthum, and Cymbopogon nardus, emerged as notable candidates. The findings highlight opportunities for the development of phytopharmaceuticals and natural food preservatives, while key research gaps relate to the limited availability of in vivo data, lack of standardized extraction protocols, and insufficient exploration of molecular mechanisms. Overall, this review underscores the strategic value of Lampung’s biodiversity as a source of potential antibacterial agents effective against E. coli and S. aureus.Keywords: Phytochemicals, Antibacterial activity, Escherichia coli, StaphylococcusAureus, Lampung
