Abstract

Edible film is a thin layer used to coat food or placed between food components, and it is consumable. This research aimed to assess the effect of adding teak leaf powder on the physical, chemical, and antibacterial properties of the edible film. The experiment was designed using a Completely Randomized Design (CRD), with teak leaf powder (J) as the independent variable. Four treatments were applied: J0 (0 g), J1 (0.25 g), J2 (0.50 g), and J3 (0.75 g) of teak leaf powder. Each formulation was tested for moisture content, thickness, tensile strength, elongation, water vapor transmission rate (WVTR), and antibacterial activity against environmental bacteria and Escherichia coli. The data obtained were analyzed using ANOVA followed by Tukey’s post hoc test at a significance level of α = 0.05. Physically, the addition of teak leaf powder increased the thickness of the edible film but decreased its tensile strength, elongation, and WVTR. The chemical parameter, moisture content, remained relatively stable across all treatments. In terms of antibacterial properties, the inhibition zone against environmental bacteria increased significantly. For Escherichia coli, no inhibition zone was observed in treatment J0, while treatments J1 to J3 demonstrated comparable antibacterial effectiveness.

Abstract

Corn noodles are a gluten-free and high-fiber food product, but contain relatively low levels of β-carotene. To enhance their nutritional value and visual appeal, pumpkin puree (Cucurbita moschata Duchesne), known for its high β-carotene content and natural coloring properties, was added to the formulation. This study aimed to evaluate the effects of pumpkin puree addition on the physical, chemical, and organoleptic characteristics of wet corn noodles. A completely randomized design with one factor was used, comprising four treatment levels: 10%, 20%, 30%, and 40% pumpkin puree based on the total flour weight. The results showed that pumpkin puree significantly increased moisture contents and β-carotene levels (p<0.05), with the highest values found in formulation F4 (40%)—moisture contents of 65.40% and β-carotene of 287.07 µg/100 g (db). However, formulation F3 (30%) demonstrated the most balanced attributes, including bright colour (a = 4.41and b 22.77), optimal texture (cohesiveness 0.21 and adhesiveness 1.89), and the highest overall anelist preference score (overall score 3.0). Therefore, adding 30% pumpkin puree is the optimal formulation for producing wet corn noodles that are nutritious, visually appealing, and well accepted by consumers.

Abstract

Mathematical ability is considered essential and plays a significant role in helping students solve problems in their daily lives. One important component of mathematical ability is mathematical literacy, which refers to an individual's capacity to formulate, use, and interpret mathematics in various real-world contexts. However, many students still struggle to apply mathematical concepts to everyday situations. Therefore, a learning approach that enhances students’ mathematical literacy is needed, including the use of appropriate learning media. This study employed a systematic literature review of experimental and developmental studies to examine mathematics learning media that enhance students’ mathematical literacy. The reviewed literature consisted of national and international journal articles indexed in SINTA and Scopus, published between 2015 and 2025, with students as the research subjects. The results of this study indicate that learning media such as Virtual Mathematics Kits, GeoGebra, Wingeom, Scratch, Wordwall, Kahoot, e-modules, e-LKPD, mathematics comics, Math City Map, and the selection of appropriate learning models are consistently effective in improving students’ mathematical literacy. Digital and interactive media enhance mathematical literacy through visualization, interactivity, and dynamic exploration of mathematical concepts, while contextual and non-digital media strengthen students’ abilities to formulate, employ, and interpret mathematics through real-life problem-solving and meaningful learning experiences across educational levels.

Abstract

The demands of 21st-century pedagogical competencies necessitate that Prospective Mathematics Teachers (PMTs) be proficient in the integrated application of technology and differentiation. This study aims to assess the competence of PMTs in implementing technology-enhanced differentiated instruction within an inductive learning framework, evaluated through seven key elements referencing the frameworks of Prince & Felder and Tomlinson. Utilizing a descriptive qualitative approach, this study analyzed in-depth peer teaching video recordings from the entire cohort of 15 students in a mathematics education program. The novelty of this research lies in its focus on the integrated operationalization of these three complex pedagogical elements. Data analysis was conducted rigorously using the interactive model of Miles, Huberman, and Saldana, supported by source triangulation to ensure the credibility of the findings. The results indicate that PMTs achieved high competence in inductive learning and differentiation (implemented by 93%–100% of PMTs). However, the implementation of technology-enhanced learning showed significant variance, being adequately achieved by only 67% of PMTs. It is concluded that while PMT training is robust in instructional design and differentiation strategies, the integration of technological tools requires further optimization and focused development to meet the demands of 21st-century skills.
