The rapid advancement of smartphone technology has shaped consumer buying behavior, especially among students who depend on these devices for learning and social interaction. This research examines how product features and price perceptions influence students’ decisions to purchase Oppo smartphones in Malang City. Using a quantitative research design, data were obtained through questionnaires distributed to 428 respondents and processed using multiple linear regression analysis. The findings indicate that both product features and perceived price positively and significantly affect purchasing decisions, with product features demonstrating a more dominant role. The proposed model accounts for 66.2% of the variance in purchase decisions, suggesting that these two factors play a substantial part in shaping consumer choices. The results highlight the need for manufacturers like Oppo to focus on continuous feature improvements and maintain competitive pricing to strengthen market appeal. It is also suggested that future studies integrate additional variables such as brand image, marketing promotions, or user experience to offer a broader and more in-depth explanation of the determinants influencing smartphone purchase behavior.

This study aims to determine the effect of promotion, price, and brand image on consumer purchasing decisions in the Cap Fajar Chips Home Industry. The study uses a quantitative approach with a survey method. The study population is consumers who have made purchases at the store, with a total of 150 respondents selected as a sample. The data collection method is carried out through distributing questionnaires, then the data is analyzed using multiple linear regression techniques to test the effect of each independent variable, both partially and simultaneously, on purchasing decisions. The results of the analysis show that the promotion variable (X1) does not have a partial significant effect on purchasing decisions, as evidenced by a significance value of 0.502 (> 0.05). This indicates that the intensity or form of promotion carried out is not enough to directly influence consumer purchasing decisions. In contrast to promotions, the price variable (X2) is proven to have a positive and significant effect on purchasing decisions. A significance value of 0.000 (< 0.05) indicates that competitive and affordable pricing is an important factor that encourages consumers to choose Cap Fajar chips products. Similarly, the brand image variable (X3) has a partial significant influence on purchasing decisions, with a significance value of 0.013 (<0.05). This indicates that consumers' positive perceptions of brand reputation and quality can strengthen the desire to purchase. Simultaneously, the three variables—promotion, price, and brand image—have a significant influence on consumer purchasing decisions. This finding is evidenced by a significance value of 0.001 (<0.05). Based on the results of the study, it can be concluded that price and brand image are the dominant elements that determine purchasing decisions for Cap Fajar chips, while promotions require a more effective strategy to provide a real impact.

This study aims to analyze the influence of brand ambassadors, sales promotions, and brand image on the purchase intention of Mie Lemonilo products in Balikpapan. The research utilizes both primary and secondary data. Primary data were collected through a questionnaire distributed to followers of the Mie Lemonilo Instagram account in Balikpapan, while secondary data were gathered from various supporting sources. The population in this study consisted of all followers of the Mie Lemonilo Instagram account in Balikpapan, with a sample size of 100 individuals. The results of the study indicate that Brand Ambassador (X1) does not significantly influence the purchase intention of Mie Lemonilo. This suggests that the impact of the brand ambassador on consumer purchasing decisions in Balikpapan is not strong enough, possibly due to insufficient engagement or connection between the brand ambassador and consumers. In contrast, Sales Promotion (X2) has a significant positive impact on the purchase intention of Mie Lemonilo. This indicates that sales promotions, such as discounts or special offers, have a substantial effect in attracting consumer interest and increasing purchase intention in Balikpapan. Meanwhile, Brand Image (X3) does not show a significant influence on the purchase intention of Mie Lemonilo. This may be due to other factors being more dominant in influencing consumers’ purchase decisions, such as product price, quality, or social factors and market trends. This study provides insights that, although brand image is important, sales promotions play a more significant role in driving purchase intention for Mie Lemonilo products in Balikpapan. Therefore, the company should focus more on promotional strategies to increase sales while continuing to consider the role of brand ambassadors and brand image in their marketing strategies.

This study aims to examine the influence of independent variables—Social Media, Pricing, and Promotion—on the dependent variable, Repurchase Decision, at Kedai Kopi Bersahaja. A quantitative research method was employed, utilizing multiple linear regression analysis with the assistance of SPSS 25 software. The population of the study consisted of 226 consumers, and a sample of 107 respondents was selected using incidental sampling techniques. Data were collected through questionnaires distributed to visitors who had made at least one purchase at the coffee shop. The results of the analysis indicate that each independent variable—Social Media, Pricing, and Promotion—has a positive and statistically significant partial influence on the Repurchase Decision. Additionally, the variables collectively demonstrate a strong simultaneous influence, suggesting that an integrated marketing approach is crucial for fostering customer retention and encouraging repeat purchases. Among the three, Social Media showed the most dominant influence, emphasizing the growing role of digital presence and online engagement in shaping consumer preferences and purchasing patterns. Based on these findings, it is recommended that Kedai Kopi Bersahaja maximize the use of social media platforms such as Instagram, TikTok, and Facebook by creating engaging, relevant, and interactive content that resonates with the target audience. Content strategies may include customer testimonials, behind-the-scenes videos, product highlights, and limited-time offers. Pricing should be evaluated periodically to remain affordable yet profitable, considering both market competition and perceived customer value. Meanwhile, promotion efforts can be diversified through the use of loyalty programs, bundle offers, student discounts, and digital coupons. The synergy between these three marketing factors—if consistently and strategically applied—is expected to enhance customer loyalty, strengthen brand image, and significantly increase the likelihood of repurchase decisions. These efforts are essential for building sustainable business growth in the competitive food and beverage industry.

This study aims to analyze the influence of Product Quality, Price, Sales Promotion, and Advertising on consumer purchasing decisions on the Bukalapak online store platform. This study used a quantitative approach with descriptive methods, aiming to illustrate the relationships between variables based on empirical data. Primary data were obtained by distributing questionnaires to 120 respondents who were active Bukalapak users in the West Medan District. The data analysis technique used was multiple linear regression with the aid of SPSS software to determine the effect of each independent variable on the dependent variable. The analysis results indicate that, partially, the variables Product Quality, Sales Promotion, and Advertising have a positive and significant influence on purchasing decisions. This means that the higher the product quality, the more effective the promotion, and the more attractive the advertisement, the greater the likelihood of consumers making a purchase. Conversely, the variable Price showed a negative and significant influence, indicating that inappropriate pricing can reduce purchase intention. Simultaneously, all four variables have a significant influence on purchasing decisions. The Adjusted R Square value of 70.4% indicates that this research model is able to explain 70.4% of the variation in purchasing decisions, while the dependent variable is influenced by factors outside the model. This study recommends that Bukalapak continue to improve product quality, develop competitive pricing strategies, strengthen promotions, and create creative advertising. Further research is recommended to consider additional variables such as product reviews, brand image, and service quality to enrich the analysis.
