The Merdeka Curriculum in Indonesia represents a transformative educational reform emphasizing holistic student development. However, conventional assessment methods have proven inadequate in comprehensively evaluating these desired learning outcomes. This study employs bibliometric analysis to systematically examine the research landscape surrounding the multiple assessment in the context of Merdeka Curriculum. Through data mining from the Google Scholar database spanning 2018 to 2023, the findings reveal a significant gap between the substantial academic interest in multiple assessments, as evidenced by 2,727 citations from 660 publications, and the limited number of studies (92 articles with 187 citations) explicitly focused on developing new assessment instruments. Keyword analysis further highlighted the under representation of terms like "assessment instrument" and "development," signaling a need for intensified research efforts in this domain. The study's findings underscore the urgent necessity for developing innovative assessment tools that transcend traditional knowledge-based testing methods. These new assessments hold the potential to elevate the quality of education in Indonesia, better preparing students to navigate the complexities of the 21st century global landscape.

Red betel (Piper ornatum) is an ornamental plant with potential antibacterial and antioxidant properties due to its bioactive compounds, including alkaloids, flavonoids, steroids, triterpenoids, saponins, and tannins. This study aimed to determine the relationship between flavonoid content, antioxidant activity, and antimicrobial activity in red betel leaves. Ultrasound-Assisted Extraction (UAE) was employed using three solvents of varying polarity: n-hexane (non-polar), ethyl acetate (semi-polar), and ethanol (polar). Total flavonoid content was determined spectrophotometrically based on flavonoids' ability to form complexes with AlCl3. Antioxidant activity was assessed using the DPPH (2,2-diphenyl-1-picrylhydrazyl) method. Antibacterial and antifungal properties were evaluated through Minimum Inhibitory Concentration (MIC) and Zone of Inhibition (ZOI) tests. MIC was determined using the agar dilution method, while ZOI was measured using the disc diffusion method. Results showed that the 96% ethanol extract yielded the highest flavonoid content (4.748%) and the strongest antioxidant activity (IC50 = 47.185 ppm, classified as very strong). The n-hexane extract at 25% concentration exhibited the best antibacterial activity against Streptococcus mutans (ZOI = 17.43 mm), while the 96% ethanol extract at 25% concentration demonstrated the highest antifungal activity against Candida albicans (ZOI = 17.02 mm). In conclusion, red betel leaf extracts show promising potential as strong antioxidants and antimicrobial agents against C. albicans and S. mutans.

Giant ginger is a rhizome plant known as a spice and herbal medicine originating from South Asia, for preventing or treating various diseases because it contains gingerol. To increase the production of giant ginger plant seeds besides cultivation it can be done by utilizing in vitro culture techniques. The aim and novelty of the research is to obtain a new in-vitro medium that is suitable for producing ginger plant seeds with good and uniform quality.The research was carried out in January-December 2023. The explants used were giant ginger culture in vitro collected from the Tissue Culture Laboratory, Center for Biotechnology and Agricultural Genetic Resources. The explants were grown on MS media with the addition of a combination treatment of growth regulators BAP (0, 1, and 5 mg L-1) and TDZ (0.0, 0.1 and 0.2 mg L-1) then continued with the acclimatization process. The experimental design used was a Completely Randomized Factorial Design. The research results showed that in in-vitro the combination of 1.0 mg L-1 BAP treatment without the addition of TDZ was chosen as the ZPT concentration treatment level because it produced the best response to the growth of large white ginger explants. And in ex-vitro, the treatment combination of BAP 1.0 + TDZ 0.1, BAP 1.0 mg L-1 without the addition of TDZ, and control was chosen as the ZPT concentration treatment level because it produced the best response to the growth of giant ginger explants.
