Abstract

Biology learning, particularly the abstract topic of the Excretory System, demands high visualization, which is often lacking in conventional media. This Research and Development (RD) study, utilizing the ADDIE model and focusing on the validation stage, aimed to develop and assess the academic feasibility of a digital learning medium based on Lecture Maker software. Following a thorough analysis of curriculum objectives and student needs, the product was designed to integrate text, images, animations, and videos to present complex physiological concepts. Product validity was rigorously assessed by both subject matter and media experts, yielding an average total score of 4.15, which categorizes the medium as "Valid". Detailed results showed high scores for design/structure (4.19) and language (4.50), while the content/substance aspect received the lowest rating (Sufficiently Valid, 3.76), indicating specific areas for revision concerning the simplification of scientific language and enhanced visualization. In conclusion, the developed Lecture Maker-based medium is declared academically feasible and valid, fulfilling the criteria for quality educational media and is ready to be utilized in the subsequent implementation stage to assess its practical effectiveness on student learning outcomesKeywords:  Lecture Maker,  Learning Media,  Excretory System,  Validation,  ADDIE Model

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 implementation of the Merdeka Curriculum requires biology teachers to adapt to more flexible, student-centered, and competency-based learning approaches; however, in practice, they still face various challenges at the school level, including at SMAN 1 Kolaka. This study aims to explore the implementation of the Merdeka Curriculum by a Biology teacher at SMAN 1 Kolaka and to identify various challenges encountered during the learning process. A descriptive qualitative approach was employed, with data collected through structured interviews conducted with a Biology teacher of Grade X. The data were analyzed using thematic analysis, which included transcription, coding, and interpretation. The findings indicate that the Merdeka Curriculum has been implemented and is considered more efficient, fostering a more meaningful and enjoyable learning experience for students. However, the teacher still faces difficulties in delivering material to students with diverse cognitive abilities. The study concludes that enhancing teacher competence in designing adaptive lesson plans (RPP) and utilizing technology are crucial strategies to overcome instructional challenges and optimize the implementation of the Merdeka Curriculum. Keywords:  Merdeka Curriculum, Biology Teacher, Curriculum Implementation, Lesson Plan (RPP).

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
