The Impact of Quality, Price, Brand Image, and Social Media Promotion2025-09-04T18:15:55+07:00Gita Amalia Putrizainal.zawir@yarsi.ac.idZainal Zawir Simonzainal.zawir@yarsi.ac.id<p>This study was conducted to investigate the impact of Product Quality, Price Perception, Brand Image, and social media promotion on purchasing decisions for Skintific Skincare. The samples used in this study were users and users of Skintific. The sampling technique used a non-probability sampling method, with a purposive sampling technique. The data collection method used a questionnaire. Data analysis used multiple linear regression analysis. The study's results showed that product quality has a partial and significant positive effect on purchasing decisions. (2) Price perception does not have a significant effect on purchasing decisions. (3) Brand image does not have a significant effect on purchasing decisions. (4) Promotion has a positive and significant effect on purchasing decisions. The managerial implications of this study are that Skintific can improve purchasing decisions by strengthening product quality and promotion strategies on social media, as these two factors have been shown to have a significant effect. In addition, although price perception and brand image do not have a significant effect in this study, the company still needs to consider competitive pricing strategies and strengthen brand image to increase competitiveness in the market.</p>2025-09-25T00:00:00+07:00Copyright (c) 2025 Gita Amalia Putri, Zainal Zawir Simonhttps://sanscientific.com/journal/index.php/reb/article/view/499Macroeconomic Determinants of Stock Returns in the Indonesian Food and Beverage Industry2025-09-04T18:04:13+07:00Fahri Gunawan Siagianpardomuan.sihombing@mercubuana.ac.idPardomuan Sihombingpardomuan.sihombing@mercubuana.ac.id<p>The objective of this study is to examine the influence of macroeconomic variables specifically exchange rates, interest rates, and inflation on stock returns, both directly and indirectly through beta, within the food and beverage sector. Additionally, it explores the impact of the COVID-19 pandemic. This research adopts a quantitative approach, targeting companies listed on the Indonesia Stock Exchange within the food and beverage industry. Secondary data, sourced through library research, underpins the study, which employs panel data analysis as a primary method. The findings indicate that inflation does not negatively affect stock returns, similar to interest rates and exchange rates, which also show no adverse impact. Furthermore, the COVID-19 pandemic was found to have no positive influence on stock returns in this sector. Regarding systematic risk, beta appears to diminish the effect of inflation, interest rates, and exchange rates on stock returns, while it does not amplify the impact of the COVID-19 pandemic. These results carry significant implications for managers and investors, suggesting that external macroeconomic conditions and beta are not the key determinants of stock returns.</p>2025-09-26T00:00:00+07:00Copyright (c) 2025 Fahri Gunawan Siagian, Pardomuan Sihombinghttps://sanscientific.com/journal/index.php/reb/article/view/418The Power of Brand Love: Unlocking Loyalty Through Image, Trust, and Satisfaction2025-09-04T18:18:50+07:00Dody Hadi Wijayaamin.mansur@yarsi.ac.idAmin Mansuramin.mansur@yarsi.ac.id<p>This study evaluates the influence of Brand Image, Brand Trust, and Customer Satisfaction on Brand Loyalty, with Brand Love as a mediating variable. The research targeted Pantene Shampoo customers in the Kelapa Gading area, using questionnaires for data collection and multiple regression analysis for testing. Results show that Brand Image significantly affects Brand Love, while Brand Trust has a positive but insignificant effect. Customer Satisfaction, however, exerts a significant positive impact on Brand Love. In terms of Brand Loyalty, Brand Image has a positive yet insignificant effect, whereas both Brand Trust and Customer Satisfaction significantly strengthen loyalty. Brand Love itself also significantly enhances Brand Loyalty. Furthermore, Brand Image and Brand Trust have significant indirect effects on Brand Loyalty through Brand Love, while Customer Satisfaction does not demonstrate such an indirect effect. The managerial implications highlight the importance of strategies that go beyond functional value to build emotional connections with consumers. Companies should focus on strengthening Brand Love, as it plays a central mediating role. This can be achieved through consistent brand communication, maintaining product quality, and fostering authentic consumer engagement, all of which contribute to stronger and more sustainable loyalty.</p>2025-09-26T00:00:00+07:00Copyright (c) 2025 Amin Mansur, Dody Hadi Wijayahttps://sanscientific.com/journal/index.php/reb/article/view/414Unraveling the Impact of Psychological Contract Breach on Work Engagement and Life Satisfaction in Generation Z2025-09-04T18:11:44+07:00Alfiah Fill Kholqi Yusupalfiahfill@gmail.comHendryadi Hendryadialfiahfill@gmail.com<p>This study examines the relationship between psychological contract breach, work engagement, and life satisfaction in Generation Z individuals working in various sectors in Jakarta. Using a quantitative approach, data were collected through questionnaires distributed to 158 respondents aged 21 to 27 years working in various sectors. The sampling technique employed was purposive sampling, while data analysis was conducted using Structural Equation Modeling (SEM) with Confirmatory Factor Analysis (CFA) and regression tests via Jamovi software. The study's results indicate that psychological contract breach has a negative and significant impact on life satisfaction. In contrast, life satisfaction has a positive and significant impact on work engagement. In addition, psychological contract breach also harms work engagement, both directly and indirectly, through its impact on life satisfaction. This study provides new insights into the complex dynamics between psychological contract breach and work engagement, especially in understanding the engagement of Generation Z employees.</p>2025-09-26T00:00:00+07:00Copyright (c) 2025 Alfiah Fill Kholqi Yusup, Hendryadi Hendryadihttps://sanscientific.com/journal/index.php/reb/article/view/515Measuring Stock Value: The Impact of Financial Ratios on a Company's Stock Price2025-09-23T10:59:18+07:00Mutia Karimamuhammad.ghazali@yarsi.ac.idMuhammad Ghazalimuhammad.ghazali@yarsi.ac.id<p>This study aims to analyze the effects of the Debt-to-Equity Ratio (DER), Price-to-Book Value (PBV), Price-to-Earnings Ratio (PER), and Return on Assets (ROA) on stock prices. This study utilized a sample of food and beverage consumer goods industry companies listed on the Indonesia Stock Exchange (IDX) for the period from 2019 to 2021. The sampling technique employed in this study was purposive sampling, involving 12 companies. The method employed in this study is quantitative and utilizes secondary data. The research model employs multiple linear regression, utilizing the SPSS version 25 application. The results of this study are partial, specifically that the DER, PBV, PER, and ROA variables do not have a significant effect on stock prices. Simultaneously, all variables namely, DER, PBV, PER, and ROA do not affect stock prices. This research is expected to focus not only on the company's profit but also on its ability to generate cash, as it is only an illustration of the company's short-term performance. In addition, investors also need to pay attention to the performance of the company's organizational governance tools, so that they can obtain better corporate action information to inform their investment decisions.</p>2025-09-27T00:00:00+07:00Copyright (c) 2025 Mutia Karima, Muhammad Ghazali
