Abstract

This study aims to develop and test the effectiveness of the STEMpreneur Herbal Model as a STEM-based learning innovation integrated with local wisdom through the use of herbal plants to improve students' 21st-century skills. Using a mixed-methods approach with an explanatory sequential design, the study involved 32 Grade XI students from SMA Negeri 1 Karas Magetan through six weeks of project-based learning. Quantitative data were collected through critical thinking tests, creativity questionnaires, collaboration, and entrepreneurial literacy, while qualitative data were obtained from observations and interviews. The results showed a significant increase in critical thinking (Cohen's d = 1.21), creativity (+36.7%), collaboration (+25%), and entrepreneurial literacy (+30%), with the first three variables being the main predictors of entrepreneurial literacy. Qualitatively, students showed high engagement, appreciation for local knowledge, and increased motivation to learn. The Herbal STEMpreneur model proved effective in fostering 21st-century competencies, strengthening the Pancasila Student Profile, and contextualising science in real life. Wider implementation is recommended through interdisciplinary teacher training, adaptation of a curriculum based on regional potential, and collaboration with MSMEs and universities to support the sustainability of relevant and character-building STEM education.

Abstract

The purpose of this study was to examine the impact of corn flour substitution on the sensory characteristics of mocaf-based tartlet skin, while determining the most optimal formulation. Variations of corn flour substitution consisting of four levels (10%, 20%, 30%, and 40%) to mocaf flour were tested using a completely randomized experimental design. The hedonic quality test involved 30 semi-trained panelists who assessed four sensory attributes including color, aroma, taste, and texture using a rating scale of 1 to 4. Data were analyzed using the Kruskal-Wallis non-parametric test followed by a post-hoc test using Dunn-Bonferroni with a correction of α' = 0.05/6 = 0.0083. The results showed that corn flour substitution had a significant effect (p < 0.05) on the color (p < 0.001), aroma (p = 0.006), and texture (p = 0.003) of mocaf-based tartlet skin, but had no significant effect on the taste (p = 0.200). The best formulation was found in sample A4 (60% mocaf: 40% corn flour) which produced a characteristic brownish yellow color, dominant corn aroma, and the crispiest texture.

Abstract

The substitution of rice bran flour and the incorporation of moringa leaf powder were examined in relation to their effects on the sensory acceptability of soft cookies, evaluated across the parameters of color, aroma, taste, and texture. A quantitative experimental design was employed, comprising six treatment combinations: B1K1 (10% rice bran flour and 5% moringa leaf powder), B2K1 (20% rice bran flour and 5% moringa leaf powder), B3K1 (30% rice bran flour and 5% moringa leaf powder), B1K2 (10% rice bran flour and 10% moringa leaf powder), B2K2 (20% rice bran flour and 10% moringa leaf powder), and B3K2 (30% rice bran flour and 10% moringa leaf powder). Preference levels were evaluated by 30 semi-trained panelists through a five-point hedonic test, and all collected data were subsequently analyzed using Two-Way ANOVA. The results indicated that the substitution of rice bran flour did not exert any significant effect on the product's color, aroma, taste, or texture. The addition of moringa leaf powder at a concentration of 10% influenced aroma, taste, and texture as the primary sensory attributes, whereas the addition at 5% produced a significant effect only on aroma, with no notable impact on color, taste, or texture. Moreover, the analytical findings confirmed that no interaction effect existed between the two treatment factors across any of the sensory attributes assessed.
