Abstract

Dodolan Hijab is a hijab shop located on Jl. Medayu Utara Gg. VIII A No.19, Medokan Ayu, Surabaya. This shop offers various types of hijab, with Hijab Paris being one of the most popular and in-demand products. However, for some time, there has been a significant problem related to the high level of damage to Hijab Paris products, which includes 33% torn hijabs, 35% slanted cuts, and 32% pulled threads. This study aims to identify the types of defects that cause the high defect rate in Hijab Paris products over 12 month, as well as to analyze the factors that affect their quality. For this reason, the Six Sigma, New Seven Tools, and Kaizen approaches were applied to analyze the root cause and provide improvement solutions. Of the 11,745 hijabs produced, 281 units were found to be damaged. The results of the study showed that torn hijab defects were a top priority to be repaired in order to improve overall product quality. The suggested improvements were expected to make the production process more efficient, enhance the quality of Paris hijab products, and ultimately increase customer satisfaction.

Abstract

This study's goal was to compare the usability of the websites for the Industrial Engineering and Chemical Engineering departments at a university. Since these sites are critical for new students seeking information, a user-friendly interface is essential for efficient and accurate information retrieval. To conduct the study, a user performance test was administered to 40 new students, all with less than a year of study. They were asked to complete three specific tasks: downloading a form, finding a "kaleidoscope" (a summary of activities), and locating information about oral exam registration. The researchers collected data on the time students took to complete the tasks (efficiency) and the number of errors they made. This data was t hen analyzed using a Two-Way ANOVA statistical method. The results showed significant differences in usability between the two websites, with a very strong interaction effect for both efficiency and error rates. The Industrial Engineering website was most efficient for downloading a form but proved to be the least efficient for finding the kaleidoscope. Conversely, the Chemical Engineering website was most efficient for finding the kaleidoscope but was the least efficient for form downloads. Regarding errors, finding the kaleidoscope and downloading a form presented the most significant challenges, while registering for the oral exam was the least error-prone task. These findings highlight the importance of making specific, tailored improvements to academic web design to enhance the user experience on these platforms.   Keywords – Usability; University Website; User Experience; Efficiency; Error Rates

Abstract

Peningkatan daya saing UMKM di era digital penting untuk direalisasikan dan tentunya memiliki tantangan utama, terutama di Kelurahan Kertajaya, Surabaya, yang memiliki potensi besar tetapi masih kurang dalam aspek pemanfaatan media digital dan branding. KKN 57 UPN "Veteran" Jawa Timur melakukan pengabdian ini dengan pendekatan partisipatif-edukatif melalui sosialisasi literasi digital dan strategi pemasaran, pembuatan katalog UMKM, dan sosialisasi literasi keuangan. Pelaku usaha di RW 3, 6, dan 7 yang turut terlibat dalam kegiatan ini. Hasil menunjukkan bahwa pelaku UMKM lebih memahami strategi promosi visual dan pengelolaan usaha yang lebih terstruktur. Meskipun keterbatasan waktu dan kesiapan individu menjadi kendala, keterlibatan aktif peserta dan dukungan wilayah menjadi keuntungan program. Melalui pendampingan lanjutan dan kolaborasi berbagai pihak, program ini memiliki potensi untuk berkembang secara berkelanjutan. Aktivitas ini penting sebagai pondasi untuk pemberdayaan ekonomi lokal yang fleksibel dan kompetitif di era digital.

Abstract

Brand XYZ is a global apparel company that emphasizes comfort, durability, and design aesthetics in its product offerings. This study aims to examine the influence of clothing material type on purchase interest among consumers aged 18–22 years. A quantitative research approach was applied, using data collected from 50 respondents via a structured questionnaire on a 5-point Likert scale. Statistical analyses were performed using SPSS, including the Kolmogorov–Smirnov test for normality, a linearity test, Pearson correlation analysis, and simple linear regression. The results show that the data met the normality assumption (p = 0.859) and revealed a strong positive correlation between clothing material type and purchase interest (r = 0.810, p < 0.001). The regression model was found to be significant (F = 91.728, p < 0.001) with the equation Y=1.932+0.859XY = 1.932 + 0.859XY=1.932+0.859X and an R2R^2R2 value of 0.656, indicating that 65.6% of the variance in purchase interest can be explained by the clothing material type. The findings highlight the critical role of material selection in influencing consumer behavior. Practical recommendations for Brand XYZ include diversifying high-quality material options, improving transparency in fabric information, and implementing targeted consumer education campaigns to enhance brand loyalty and purchase intention.

Abstract

This study addresses the critical need to design a safe and functional food storage solution by re-engineering a lunch box product based on consumer requirements. The research problem centers on the prevalent use of harmful materials like BPA and lead in existing products, which poses health risks to users. Our methodology combines Quality Function Deployment (QFD) and the Theory of Inventive Problem Solving (TRIZ) to tackle this issue. QFD was used to transform detailed customer needs, identified through a Voice of Customer (VOC) survey, into specific technical specifications. The resulting House of Quality (HoQ) revealed two primary contradictions: one between ensuring food-grade material safety and offering a product warranty, and another between using high-quality, safe materials and maintaining an affordable price. To resolve these conflicts, TRIZ principles, specifically Cheap Short-Living Objects and Composite Materials, were applied. This approach led to a product design that is not only robust and practical, with features such as high-density seals and segregated compartments, but also scientifically sound in its use of safe materials. The findings demonstrate a successful integration of market needs and creative problem-solving to develop a product that is both commercially viable and fundamentally safer for consumers.
