Abstract

This study examines the influence of Discount Programs and Special Offers on consumer Purchasing Decisions at Matahari Department Store, Thamrin Plaza Medan. The research is important because promotional strategies are widely used in retail, yet different promotional formats may generate unequal consumer responses. A quantitative explanatory design with a cross-sectional survey approach was employed. Primary data were collected through questionnaires administered to 70 consumers selected from a population of 230 customers using incidental sampling. The data were analyzed using multiple linear regression, partial t-tests, simultaneous F-tests, and the adjusted coefficient of determination with SPSS version 16. The findings show that Discount Programs have a positive but statistically insignificant effect on Purchasing Decisions, with a regression coefficient of 0.242, a t-value of 1.698, and a significance value of 0.094. In contrast, Special Offers have a positive, significant, and dominant effect, with a coefficient of 0.686, a t-value of 5.869, and a significance value of 0.000. Simultaneously, both variables significantly affect Purchasing Decisions and explain 44.9% of their variation. These findings imply that retailers should prioritize relevant, transparent, and value-added Special Offers while using conventional discounts selectively. The originality of this study lies in revealing the differential and complementary effects of two promotional mechanisms within an offline department-store context, showing that consumers respond more strongly to additional value, urgency, and exclusivity than to price reductions alone.

Abstract

This overseas lecturer community service program aimed to strengthen knowledge exchange through cooperation between Yayasan Lembaga Manajemen Indonesia/Institut Bisnis dan Komputer Indonesia and Yayasan Basmi Kemiskinan Selangor Malaysia. It was conducted on 30 July 2026 in Petaling Jaya, Selangor, Malaysia, through planning, preparation, implementation, and evaluation stages. The activity focused on the strategic role of international cooperation in improving lecturer research and community service, including strengthening research networks, exchanging academic experiences, improving lecturer competence, and supporting the implementation of the Tri Dharma of Higher Education. The material presentation was followed by discussion and oral evaluation to determine participants’ understanding of the topics delivered. The results showed that participants understood the material well and valued the exchange of knowledge and institutional experience. Continued cooperation between both institutions is expected to strengthen lecturer competence, expand international academic collaboration, and improve the implementation of research and community service activities.
