Abstract

            Starfruit wuluh, scientifically known as Averrhoa blimbi L., contains secondary metabolites such as flavonoids and tannins, which function as antibacterial agents. The extract of starfruit wuluh leaves is formulated into a ointment for easy application. The selection of a suitable ointment base is crucial to achieve the formulation's effectiveness. Understanding the influence of using different bases, specifically oil-in-water emulsion base and water-soluble ointment base, on the stability of ointment containing ethanol extract of starfruit wuluh leaves is the aim of this research. Stability testing is conducted for two weeks at room temperature. Physicochemical tests include organoleptic evaluation, homogeneity, adhesiveness, pH, and spreading ability of the formulation. The results indicate that the variation in the type of base does not affect organoleptic aspects, homogeneity, and pH during storage but does impact adhesiveness and spreading ability of the ointment containing starfruit wuluh leaf extract during storage

Abstract

Turi is one of the plants that has activity as an antimicrobial, antifungal, anti-inflammatory and antioxidant. The content of secondary metabolites in turi leaves are flavonoids, tannins, and alkaloids. Tannins are phenol compounds with hydroxy groups and several other groups such as carboxyl. This study aims to determine the difference in total tannin levels in turi leaf extracts of red and white varieties. The extraction process with maceration using 70% ethanol solvent. Then the extract obtained was carried out screening tests, thin layer chromatography tests, and determination of tannin levels by UV-Vis spectrophotometry. Parameters of analytical method validation were carried out by determining linearity, accuracy, precision, LOD and LOQ. The results of the validation of the linearity analysis method obtained a linear regression equation y = 0.0038x + 0.3153 r value = 0.9985. The accuracy results obtained are in the range of 97-103%, RSD value of 0.18% and the LOD value is 6,213 ppm and LOQ is 20,711 ppm. The measurement results of total tannin content in turi leaf extracts of red and white varieties at a wavelength of 750 nm are 7.876% w / w TAE and 9.195% w / w TAE, respectively. Independent sample T-test results show there is a significant difference (p < 0.05) in the total tannin content of turi leaf extracts of red and white varieties.

Abstract

This study evaluates the implementation of the Merdeka Curriculum in strengthening literacy and numeracy learning at an elementary school in Grobogan Regency, Indonesia. Despite the policy emphasis on flexible and student-centered learning, schools often face difficulties translating curriculum reforms into effective classroom practices. This study applies the CIPP (Context, Input, Process, Product) evaluation model integrated with the Taba curriculum development approach to analyze curriculum implementation and teacher practices. A qualitative case study design was used involving one school principal and six teachers at SD Negeri 7 Kuripan. Data were collected through semi-structured interviews, participatory classroom observations, and document analysis of curriculum and literacy programs. The data were analyzed using thematic analysis aligned with the CIPP framework and validated through data triangulation. The findings show the need to strengthen literacy–numeracy learning, improve instructional resources, support reflective teacher practices, and enhance the organization of school literacy programs. The study provides practical insights for improving curriculum implementation in elementary education.
