Abstract

This study aims to examine the effect of participation in the Berkain campaign on social media on students’ understanding of batik. A quantitative approach with a survey method was employed. Data were collected through questionnaires to measure campaign participation and multiple-choice tests based on Bloom’s cognitive taxonomy at levels C1 (knowledge), C2 (understanding), C3 (application), and C4 (analysis) to assess students’ understanding of batik. The research population consisted of students of the Fashion Design Education Study Program at Jakarta State University from the 2022–2025 cohorts. Stratified random sampling was applied, resulting in a total of 163 respondents. Data analysis was conducted using simple linear regression. The results indicate that participation in the campaign shows a positive relationship with students’ understanding of batik; however, the t-test revealed a significance value of 0.064 (Sig. > 0.05), indicating that the effect is not statistically significant. The coefficient of determination (R Square) of 0.021 suggests that campaign participation explains only 2.1% of the variance in students’ understanding of batik, while the remaining variance is influenced by other factors outside the research variables. It can be concluded that although students’ participation in the Berkain campaign on social media is classified as moderate to high, it does not significantly affect their cognitive understanding of batik. Therefore, strengthening batik comprehension within Fashion Design Education courses is necessary. Keywords : batik,  fabric campaign, participation, understanding

Abstract

Skin hydration plays a critical role in maintaining skin health and preserving skin barrier integrity, while impairment of the barrier may increase transepidermal water loss and lead to dry, sensitive, and irritated skin. The growing interest in biomolecule-based cosmetic ingredients has encouraged the development of innovative moisturizers containing Salmon DNA (Sodium DNA), a purified nucleic acid fragment with potential hydrating properties. This study aimed to formulate and characterize Selvique DNA Salmon Hydra Moist, a moisturizer incorporating Sodium DNA together with humectants, emollients, and skin-conditioning agents to support skin hydration and barrier function. The formulation was prepared using Sodium DNA, glycerin, butylene glycol, saccharide isomerate, allantoin, caprylic or capric triglyceride, cyclopentasiloxane, and complementary excipients, followed by physicochemical and microbiological evaluations. The resulting product exhibited desirable characteristics, including a white cream appearance, odorless profile, pH of 5.27, viscosity of 110,000 cPs, and specific gravity of 1.0092 g/mL. Microbiological analysis demonstrated compliance with cosmetic quality requirements, with total plate count and yeast-mold count of 0 cfu/mL and negative results for Staphylococcus aureus, Pseudomonas aeruginosa, and Candida albicans. The formulation was also classified as non-hazardous according to the ASEAN Cosmetic Directive and remained stable under normal storage conditions. These findings indicate that the developed Salmon DNA-based moisturizer possesses acceptable physicochemical stability and microbiological quality, supporting its potential use as a biomolecule-based cosmetic formulation designed to maintain skin hydration and promote skin barrier function.
