Abstract

The rapid expansion of online shopping has reshaped consumer behavior; however, offline shopping remains preferred under certain conditions. This study examines satisfaction dimension gaps between online and offline shopping among university students using a repeated binary measures design. Data were collected through a questionnaire containing eight satisfaction indicators measured on a dichotomous scale (yes/no) from 26 respondents. Cochran’s Q test was applied to assess whether satisfaction proportions differ across dimensions, followed by McNemar’s test as an exploratory post-hoc procedure to provide diagnostic insights into the largest dimension gaps. The findings reveal meaningful variation across satisfaction dimensions. Online shopping demonstrates stronger satisfaction in convenience and payment security, while offline shopping shows higher satisfaction in product trial experience and perceived product assurance. Nevertheless, offline shopping exhibits comparatively lower satisfaction in service-related dimensions, indicating a potential weakness in interpersonal service delivery. These results confirm that consumer satisfaction is multidimensional and that satisfaction gaps across shopping channels are not uniform. The study offers practical insights for businesses to formulate channel-specific strategies to improve service quality and customer experience in both online and offline retail environments.

Abstract

Kegiatan pengabdian kepada masyarakat ini dilatarbelakangi oleh permasalahan keterbatasan alat pengolahan jagung dan praktik pembakaran limbah pascapanen yang merusak lingkungan di Desa Kolam, Kecamatan Percut Sei Tuan, Kabupaten Deli Serdang. Hal ini berdampak pada rendahnya nilai ekonomi petani dan masalah lingkungan. Program ini bertujuan untuk meningkatkan efisiensi pascapanen, meningkatkan nilai ekonomi jagung pipil, serta mendorong praktik pertanian berkelanjutan melalui pemanfaatan limbah menjadi silase. Pendekatan yang digunakan adalah deskriptif-kualitatif dengan teknik observasi lapangan, pelatihan teknis penggunaan mesin pipil jagung, serta pelatihan pembuatan pakan fermentasi (silase) berbasis limbah pertanian. Hasil kegiatan menunjukkan adanya peningkatan efisiensi pascapanen, kenaikan nilai jual jagung pipil, serta terwujudnya praktik zero-waste melalui pemanfaatan limbah sebagai silase. Selain itu, program ini memperkuat kapasitas petani dan mendorong integrasi sistem pertanian-peternakan berkelanjutan. Program pengabdian ini berhasil menjawab permasalahan petani melalui adopsi teknologi tepat guna dan inovasi pengelolaan limbah. Selain meningkatkan kesejahteraan petani, kegiatan ini mendukung pencapaian SDGs Nomor 15 dan dapat direplikasi di wilayah agraris lain.

Abstract

The development of digital technology has transformed student consumption patterns, with Shopee becoming one of the most popular marketplaces thanks to its easy access, diverse payment methods, and aggressive promotional strategies. This study analyzes the influence of flash sales and discounts on student purchasing decisions. The method used was a quantitative survey with a questionnaire for student Shopee users, analyzed descriptively and inferentially. The results show that flash sales and discounts both have a significant influence, but their mechanisms differ. Flash sales tend to trigger impulsive decisions through urgency and FOMO, while discounts are perceived as more rational due to the financial benefits they offer. However, the emotional aspect of flash sales proved more dominant in driving purchases, even for non-priority products. These findings confirm the effectiveness of limited-time promotions in digital marketing strategies and provide critical reflection for students to be more discerning when shopping online
