Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh promosi dan kualitas pelayanan terhadap keputusan pembelian konsumen di Samudra Supermarket Madiun. Penelitian menggunakan pendekatan kuantitatif dengan metode survei terhadap 96 responden yang dipilih menggunakan teknik purposive sampling. Data dikumpulkan melalui kuesioner dan dianalisis menggunakan regresi linier berganda. Hasil penelitian menunjukkan bahwa secara parsial promosi berpengaruh positif dan signifikan terhadap keputusan pembelian dengan nilai t hitung sebesar 2,887 dan signifikansi < 0,05. Kualitas pelayanan juga berpengaruh positif dan signifikan terhadap keputusan pembelian dengan nilai t hitung sebesar 5,248 dan signifikansi < 0,05. Secara simultan, promosi dan kualitas pelayanan berpengaruh signifikan terhadap keputusan pembelian dengan nilai F hitung sebesar 64,818 > F tabel 3,094. Nilai koefisien determinasi (R²) sebesar 0,582 menunjukkan bahwa 58,2% variasi keputusan pembelian dapat dijelaskan oleh kedua variabel independen tersebut, sedangkan sisanya dipengaruhi oleh faktor lain di luar model penelitian. Dengan demikian, dapat disimpulkan bahwa peningkatan promosi dan kualitas pelayanan mampu meningkatkan keputusan pembelian konsumen di Samudra Supermarket Madiun.

Abstract

The primary objective of this study is to analyze the contributions of price perception, electronic word-of-mouth (e-WOM), and product quality to the purchasing decisions regarding culinary MSME products among Generation Z in Bangkalan Regency. The study employs a descriptive quantitative approach using a survey method with a sample of 100 Generation Z respondents selected via purposive sampling. Data were collected using a 20-item questionnaire covering four operational variables and analyzed through multiple linear regression. Instrument testing confirmed the validity of all items, with calculated r-coefficients (0.785–0.897) consistently exceeding the critical r-table value (0.197). Internal consistency was also established, with Cronbach’s Alpha values ​​ranging from 0.907 to 0.921. Partial regression results indicate that price perception has a positive and significant impact on purchasing decisions (B=0.283; t=4.166; p<0.001). Similarly, e-WOM (B=0.342; t=4.581; p<0.001) and product quality (B=0.434; t=5.619; p<0.001) were found to exert positive and significant influences. Simultaneously, the combination of these three predictors significantly influenced the dependent variable (F=72.005; p<0.001). The Adjusted R-Square value of 0.683 indicates that 68.3% of the variation in purchasing decisions is explained by the independent variables under study, while the remaining 31.7% is attributed to external factors outside the model. Product quality emerged as the most dominant determinant.
