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

Donuts are bakery products widely consumed by the public and are generally produced using wheat flour as the main ingredient. The high dependence on wheat flour encourages the utilization of local food resources as alternative raw materials, one of which is gembili flour (Dioscorea esculenta L.). This study aimed to examine the effect of gembili flour substitution on the sensory quality and consumer acceptance of donuts. The research employed a single-factor experimental design with five substitution levels: P1 (10%), P2 (20%), P3 (30%), P4 (40%), and P5 (50%). Sensory attributes evaluated included color, aroma, taste, and texture, while hedonic assessment consisted of color, aroma, taste, texture, and overall liking. The use of gembili flour influenced product characteristics due to its high starch content and the absence of gluten, which affected dough structure, elasticity, and the final texture of the donuts. Data were analyzed using One Way Analysis of Variance (ANOVA) followed by Duncan’s multiple range test at a 5% significance level. The findings indicated that the level of substitution significantly affected sensory quality and consumer acceptance. Treatments P1 and P2 achieved the highest scores and showed no significant differences for most parameters, whereas higher substitution levels tended to reduce product acceptability. Therefore, gembili flour substitution up to 10-20% is considered optimal for producing donuts with acceptable sensory quality and consumer preference.

Abstract

Kopi merupakan stimulans yang banyak dikonsumsi oleh dewasa awal dan berpotensi memengaruhi fungsi kognitif serta indikator stres. Namun bukti hubungan antara konsumsi kopi dan kecenderungan stres masih kontradiktif. Penelitian ini bertujuan mengetahui hubungan antara konsumsi kopi (ekspektasi efek kafein) dan kecenderungan stres pada dewasa awal. Desain korelasional dengan pengumpulan data melalui kuesioner daring. Sampel terdiri dari 120 responden dewasa awal (usia 18–25 tahun). Instrumen yang digunakan adalah Caffeine Expectancy Questionnaire (CEQ) untuk mengukur konsumsi/ekspektasi kopi dan Perceived Stress Scale (PSS-10) untuk mengukur kecenderungan stres. Analisis meliputi uji asumsi normalitas (Kolmogorov–Smirnov) dan korelasi Pearson. Sampel (N = 120) terdiri dari 60,0% perempuan (n = 72) dan 40,0% laki-laki (n = 48); 78,3% mahasiswa dan 21,7% pekerja muda. Frekuensi konsumsi kopi: 57,5% (1–2 kali/hari), 32,5% (3–4 kali/hari), 10,0% (>4 kali/hari). Rata-rata skor CEQ = 3,21 (SD = 0,82; rentang 1,45–5,62) menunjukkan ekspektasi efek kopi pada tingkat sedang. Rata-rata skor PSS-10 = 22,84 (SD = 5,71; rentang 9–36) menunjukkan tingkat stres sedang. Hasil korelasi Pearson menunjukkan koefisien r = 0,312 dengan p = 0,071 (df = 118), yang berarti hubungan positif namun tidak signifikan secara statistik (p > 0,05) dan ukuran efek tergolong kecil atau lebih rendah. Pada sampel dewasa awal ini tidak ditemukan hubungan yang signifikan antara konsumsi/ekspektasi kopi dan kecenderungan stres meskipun arah korelasi positif (r = 0,312). Temuan mengindikasikan bahwa konsumsi kopi bukan penentu utama stres pada kelompok ini; faktor lain (mis. beban akademik, kualitas tidur, strategi koping) kemungkinan memiliki peran lebih besar. Disarankan penelitian lanjutan dengan desain longitudinal atau pengukuran dosis kafein kuantitatif untuk mengeksplorasi efek sebab-akibat.
