Perceived Determinants of Daily Food Choices among University Students
Food choice behavior among university students is an important public health issue because eating patterns developed during young adulthood may persist into later life. This study aimed to examine students’ perceived determinants of daily food choices using the Food Choice Questionnaire (FCQ). A quantitative descriptive design with a cross-sectional survey approach was applied to 150 undergraduate students from the Culinary Education Program at Universitas Negeri Semarang, Indonesia, selected through random sampling based on the Slovin formula. Data were collected using the FCQ consisting of 36 items across nine dimensions and analyzed using descriptive percentage analysis. The results showed that price was the most influential determinant of daily food choices (86.28%), followed by mood (83.78%), convenience (83.63%), sensory appeal (83.58%), and health (83.14%). Natural content (79.56%) and weight control (72.39%) were perceived as moderately influential, while ethical concern was the least influential determinant (68.83%). These findings indicate that students’ food choices are shaped primarily by economic, emotional, and practical considerations, suggesting an intention–behavior gap in which health awareness does not consistently translate into daily food choice behavior.

Nutritionally, fish balls have been shown to have a higher protein content and a better amino acid profile than meatballs made from red meat, and have the potential to be a source of omega-3 fatty acids and functional minerals. Bibliometric analysis shows a growing research trend since 2018, although gaps remain in method standardization, the relationship between microstructure and sensory perception, and evaluation at the MSME scale. Thus, further research needs to be directed at an integrated approach that connects instrument analysis, sensory testing, and quality predictive models to support innovation, standardization, and application of research results on an industrial and MSME scale.
Application of Ribbon Quilling Sakura Flower Embellishment on Daytime Party Dress as a Center of Interest
This study aims to explore the application of ribbon quilling technique as a decorative element in fashion design, focusing on cherry blossom motifs applied to a daytime party dress. Quilling, originally a 17th-century European paper craft, is adapted using grosgrain ribbon to create flower-shaped ornaments with a soft and elegant visual character. The novelty of this research lies in the use of ribbon-based quilling as an alternative approach for decorating formal wear, which has been scarcely explored in fashion design practice. This study employs a practice-led research approach through four main stages: exploration, design, realization, and evaluation. The exploration stage involves gathering visual references and adapting the quilling technique to the characteristics of grosgrain ribbon; the design stage includes sketch development and ornament placement; the realization stage covers the creation and application of quilling on the dress; and the evaluation stage is conducted based on the principles of unity, balance, and proportion by a fashion design expert. The results demonstrate that ribbon quilling technique can enhance the aesthetic value of formal wear by combining handcrafted skills with contemporary design approaches. These findings open opportunities for further development in accessories, costumes, and bridal wear, as well as contributing to fashion education and the preservation of handcraft-based decorative techniques.
The Effect of Fixator Type on the Color Fastness of Cotton Fabric Dyeing with Mango Leaves Extract (Mangifera indica L.)
The effect of different fixatives—alum (Al₂(SO₄)₃·18H₂O), ferrous sulfate (FeSO₄·7H₂O), and lime (Ca(OH)₂)—on the color fastness of cotton fabric dyed with natural dye extracted from mango leaves (Mangifera indica L.) was investigated. The dyeing process involved boiling fresh mango leaves, applying multiple dyeing cycles, and subsequent fixation treatments. Color fastness to washing (ISO 105-C06) and wet rubbing (ISO 105-X12) was evaluated using the gray scale, and data were analyzed with the Kruskal–Wallis test followed by Dunn’s post-hoc test. Results showed that fixative type significantly affected wash fastness (p = 0.018), with lime providing the highest mean rank, followed by alum and ferrous sulfate. In contrast, fixative type had no significant effect on wet rubbing fastness (p = 0.264). These findings indicate that alkaline fixation with lime enhances wash durability of mango leaf dyes, while wet rubbing resistance is less influenced by fixative selection. This study supports the potential of mango leaf extract as an eco-friendly dye source and provides insights for optimizing mordant selection in sustainable textile dyeing applications.
Exploring the Quality of Eco-Prints from Floral Waste Across Fabric Variations
Textile dyes are commonly used in the production of fashion products. However, to reduce reliance on synthetic textile dyes, the use of natural dyes has become an important alternative. One sustainable method for applying natural dyes is the eco-print technique. This study aimed to examine: (1) the quality of color fastness to soap washing in eco-print results on cotton, linen, and silk fabrics; and (2) the quality of color aging in eco-prints using kenikir flowers on cotton, linen, and silk fabrics. The research employed an experimental method by producing eco-prints on cotton, linen, and silk fabrics. The materials used for eco-printing included kenikir, insulin, grass, and frangipani flowers, applied through a steaming technique. Sample testing was conducted at the UII Textile Laboratory to assess color fastness to soap washing and color aging. Data were analyzed descriptively, based on three repetitions of each test. The findings revealed that the average score for color fastness to soap washing was 4–5, which falls under the good criteria. Meanwhile, the results of the color aging test showed values of 97.66 for cotton, 101.61 for silk, and 114.99 for linen. Among these, silk fabric demonstrated higher results, indicating that the eco-printed motif appeared older or darker in color compared to cotton and linen.
The Influence of Paylater Usage in E-Commerce on Impulsive Buying of Fashion Products
This research aims to determine the influence of paylater usage in e-commerce on impulsive buying of fashion products. This research uses a survey method with a quantitative approach. The sample for this research was 120 with sampling using accidental sampling technique. The data analysis technique used is the chi square test. The results of data analysis show that there is no influence between the use of the payLater payment system in e-commerce and impulsive buying of fashion products. From the results of this research, it can be concluded that consumer behavior tends to be impulsive in purchasing fashion products on e-commerce, whether using paylater or not using paylater.
Application of Digital Pattern Techniques in Ready to Wear Fashion Based on CLO3D Software
Abstract. Fashion patterns serve as the basic templates for garment creation, playing a crucial role in ensuring the fit and comfort of the resulting clothing. Advances in digital technology, particularly in fashion, have significantly transformed the design and production processes. CLO3D software allows designers to create fashion patterns in a digital 3D format, which accelerates design, reduces costs, and supports sustainability by minimizing waste. This research employs the Research and Development (R&D) method to develop a user guide for using CLO3D. The research findings indicate that digital pattern techniques enhance efficiency, accuracy, and creativity in design. Validation of the user guide by experts shows a high level of validity with a consensus index of 1.0, indicating its relevance and effectiveness in learning. This study concludes that CLO3D not only improves the quality of designs but also contributes significantly to education and skill development in the fashion field.
