Data dianalisis menggunakan regresi linear berganda, uji t, uji F, serta uji asumsi klasik. Hasil penelitian menunjukkan bahwa promosi berpengaruh positif dan signifikan terhadap keputusan mahasiswa, dengan nilai t sebesar 8,040 (sig 0,000), serta menjadi variabel yang paling dominan. Biaya pendidikan juga berpengaruh positif dan signifikan dengan nilai t sebesar 3,490 (sig 0,001). Secara simultan, kedua variabel berpengaruh signifikan terhadap keputusan mahasiswa dengan nilai F sebesar 68,097 (sig 0,000) dan kontribusi sebesar 50,6%. Disimpulkan bahwa promosi yang efektif dan biaya yang terjangkau menjadi faktor penting dalam meningkatkan keputusan mahasiswa memilih perguruan tinggi.

Abstract

Kegiatan Kuliah Kerja Nyata ini bertujuan untuk mengoptimalkan mobilitas masyarakat melalui inventarisasi data wilayah dan pembuatan penunjuk arah di Desa Sisobambowo, Kecamatan Mandrehe, Kabupaten Nias Barat. Permasalahan utama yang ditemukan adalah belum optimalnya informasi tata letak wilayah, keterbatasan data administrasi berbasis dusun, serta minimnya papan penunjuk arah menuju fasilitas dan dusun strategis. Metode pelaksanaan menggunakan pendekatan partisipatif melalui observasi lapangan, wawancara dengan perangkat desa dan masyarakat, pendataan kartu keluarga pada Dusun I sampai IV, perancangan papan penunjuk arah, pembuatan, pemasangan, pendampingan, dan evaluasi kegiatan. Hasil kegiatan menunjukkan tersusunnya rekapan data wilayah, meningkatnya pemahaman masyarakat dan pelajar mengenai pemanfaatan teknologi digital secara aman, terlaksananya kegiatan kebersihan lingkungan, serta terpasangnya papan penunjuk arah pada titik strategis menuju dusun, kantor desa, dan akses menuju Desa Gunung Cahaya. Kegiatan ini memperkuat fungsi pelayanan desa, mempermudah orientasi masyarakat dan pendatang, serta mendorong partisipasi warga dalam pemeliharaan fasilitas publik. Program ini direkomendasikan dilanjutkan melalui pemutakhiran data wilayah dan perawatan papan penunjuk arah secara berkala.

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.
