Yellow pumpkin (Cucurbita moschata) is a nutrient-rich horticultural commodity with considerable potential for development into various food products, including pudding. However, scientific information regarding the effects of pumpkin incorporation on the physicochemical and sensory characteristics of pudding remains limited. This study aimed to evaluate the influence of different proportions of pumpkin (30%, 50%, and 70%) on the physicochemical properties, vitamin C content, and sensory acceptance of pumpkin pudding. A Completely Randomized Design (CRD) was employed with three replications for each treatment. The analyses included syneresis at two storage conditions (refrigerated and room temperatured), total dissolved solids (TDS), texture (hardness), color parameters (L*, a*, b*), vitamin C content determined by iodometric titration, and a hedonic test involving 30 untrained panelists. Data were analyzed using ANOVA followed by Duncan’s Multiple Range Test (DMRT) at a 5% significance level. The results showed that increasing the proportion of pumpkin had significant effects on TDS, texture, color attributes, vitamin C content, and most sensory parameters. Higher pumpkin concentrations decreased TDS and hardness values while increasing syneresis due to higher free-water content within the gel matrix. Lightness (L*) and vitamin C levels increased proportionally with the amount of pumpkin added. Sensory evaluation revealed that the 30% pumpkin formulation received the highest scores for color, aroma, texture, taste, and overall acceptance, whereas the 70% formulation received the lowest scores, particularly for color and chewiness. These findings indicate that the 30% pumpkin incorporation provides the most optimal balance of physical quality, nutritional enhancement, and consumer acceptability.

The accelerating global environmental crisis demands the integration of sustainability within higher culinary education. This study aims to analyze the implementation of the Green Curriculum (GC) framework at Universitas Negeri Surabaya (UNESA) and Universiti Pendidikan Sultan Idris (UPSI). Utilizing a qualitative content analysis with simple frequency quantification involving 50 participants, the findings reveal that implementation is in a transitional phase marked by three fundamental gaps. First, a significant gap exists between the high level of philosophical awareness among internal stakeholders and the lack of systemic action, despite new demands for sustainability competencies. Second, implementation is critically impeded by the university support system; infrastructure ('Facilities & Infrastructure,' f=84) was the most frequent concern, creating a 'hidden curriculum' conflict in which poor facilities (e.g., wastewater treatment) contradict pedagogical goals. Third, the framework is overwhelmingly inward-looking, rendering the community participation pillar the least emphasised (frequency <2%). This research concludes that achieving a mature GC requires a radical shift from conceptual adoption to tangible systemic alignment, prioritizing investment in critical infrastructure and the institutionalization of external partnerships for holistic operational reality.

This study evaluated the effect of wheat flour substitution with purple sweet potato flour on the physical characteristics of white bread. The experiment was conducted using a Completely Randomized Design with a single factor, namely the level of purple sweet potato flour substitution at 0%, 15%, 30%, 45%, and 60%. The physical parameters analyzed included color (L*, a*, b*), texture (firmness), porosity, and dough expansion.The results showed that increasing levels of purple sweet potato flour substitution significantly affected all physical parameters of the bread (p < 0.05). Higher substitution levels resulted in a decrease in lightness (L*) and an increase in a* values, indicating darker crumb and crust color due to the presence of anthocyanin pigments. Bread firmness increased from 6.45 ± 0.13 N in the control sample to 50.16 ± 2.90 N at 60% substitution, while porosity and dough expansion decreased markedly from 45.34 ± 0.42% to 22.13 ± 1.19% and from 89.09 ± 0.02% to 15.71 ± 3.24%, respectively.Substitution of purple sweet potato flour at 30% produced bread with acceptable physical characteristics, characterized by a balanced texture, porosity, and dough expansion. Substitution levels above this threshold resulted in a significant decline in bread quality. These findings indicate that purple sweet potato flour has strong potential as a functional ingredient in white bread formulation. Keywords: flour substitution; physical characteristics; purple sweet potato flour; white bread.

The use of learning media will help educators in delivering learning materials so that they can be well understood by students. However, in culinary learning, especially in the material of plant-based food cuts, the learning media used is still dominated by conventional learning methods such as lectures. The media cannot be used to visualize the shape and technique of the pieces in the material, this causes students to tend to be passive and less interested in understanding the material presented. Thus, innovative and interactive learning media is needed to improve students' understanding. Augmented Reality (AR) was chosen as a solution because it is able to display real visuals in 3D so as to help students understand the material visually and realistically. This research aims to develop flashcard learning media with Augmented Reality (AR) on plant-based food ingredient materials, to determine the feasibility of the material and the feasibility of the media for the learning media that has been developed. The type of research and research model used is ADDIE, but the research is limited to the development stage. The subjects of this study are class X students totaling 34 students, while the object of this study is flashcard learning media with augmented reality (AR). The instruments used in this study include validation sheets of material experts and media experts on the media used. The results of this study were concluded that flashcard media with AR is in the form of printed products that include material cut from plant-based foodstuffs, the results of the material validation show a feasibility value of 91% which is included in the very feasible category. Media validation obtained an average score of 97% with a very decent category.

The availability of assessment instruments that measure Higher Order Thinking Skills in basic food processing techniques is still limited. Therefore, an appropriate instrument is needed to evaluate students’ higher-order thinking abilities. This study aimed to develop and examine the quality of a HOTS-oriented test instrument on basic food processing techniques. The research employed a Research and Development (R&D) method using the 4D model (define, design, develop, and disseminate). The test was implemented through Wayground, an online interactive learning platform used to create and administer digital quizzes and assessments. The research subjects consisted of 59 students. Data analysis included item validity using Product Moment correlation, reliability using Cronbach’s Alpha, as well as analysis of item difficulty, discrimination index, distractor effectiveness, and completion time. The results indicated that 28 out of 55 items (50.9%) were valid. The reliability coefficient reached 0.81, categorized as very high. The difficulty level was dominated by moderate items (57%), followed by easy (39.5%) and difficult items (3.5%). The discrimination index showed fair (32%), good (43%), and very good (25%) categories. Distractor effectiveness was mostly in the good (57%) and very good (25%) categories. The fastest average completion time was 22 seconds, while the longest was 1 minute and 17 seconds. These results indicate that the instrument is feasible for measuring students’ higher-order thinking skills in basic food processing techniques.

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.
