Abstract:This study examines the effects of the Dow Jones Industrial Average (DJIA), world gold prices, world oil prices, and the rupiah exchange rate on the Composite Stock Price Index (CSPI) in Indonesia. The study uses monthly…
secondary data from January 2015 to December 2025, comprising 132 observations. CSPI data were obtained from the Indonesia Stock Exchange, DJIA, gold price, and oil price data were obtained from Investing.com, while exchange rate data were sourced from Bank Indonesia. The analysis employed the two-step Engle-Granger Error Correction Model (EG-ECM) to identify long-run relationships and short-run adjustment dynamics. The long-run results show that gold prices, world oil prices, and the DJIA have positive and significant effects on the CSPI, whereas the rupiah exchange rate has a negative but insignificant effect. In the short run, the exchange rate has a negative and significant effect on the CSPI, while gold prices, oil prices, and the DJIA have positive and significant effects. The Error Correction Term coefficient of -0.1325 is negative and significant, indicating that approximately 13.25% of short-run disequilibrium is corrected each month toward long-run equilibrium. These findings imply that investors and policymakers should closely monitor global market conditions, commodity price movements, and exchange rate volatility to support investment decisions and maintain Indonesian capital market stability

st as a mediating variable. The background of this study is based on the decline and fluctuations in BuatMudah e-course sales amidst the growth of the EdTech industry and increasing competition in the educational market for content creators. This study used a quantitative approach with a survey method. Primary data were obtained by distributing questionnaires to 355 BuatMudah e-course customers. The research instrument was designed based on indicators of paid social media advertising, digital marketing content quality, customer trust, and purchase decisions. Data were analyzed using Structural Equation Modeling (SEM) and the Sobel test to examine the mediating role. The results show that paid social media advertising has a positive and significant effect on customer trust, with a path coefficient of 0.72 and a calculated t-value of 16.17. The quality of digital marketing content also has a positive and significant effect on customer trust, with a path coefficient of 0.75 and a calculated t-value of 14.41. Furthermore, paid social media advertising had a positive and significant effect on purchasing decisions with a path coefficient of 0.25 and a calculated t-value of 4.35. Meanwhile, the quality of digital marketing content had a positive and significant effect on purchasing decisions with a path coefficient of 0.14 and a calculated t-value of 2.31. Customer trust was shown to have a positive and significant effect on purchasing decisions with a path coefficient of 0.39 and a calculated t-value of 5.03. The Sobel test results indicate that customer trust mediates the effect of paid social media advertising on purchasing decisions and also mediates the effect of digital marketing content quality on purchasing decisions. Thus, purchasing decisions for the BuatMudah e-course are determined not only by advertising effectiveness and content quality, but also by the ability of these two digital marketing stimuli to build customer trust.
Abstract:This study examines service quality and social media marketing activities as determinants of revisit intention, with customer satisfaction as an intervening variable at Flui Restaurant & Cafe Bogor. The research was motivated…
vated by the decline in customer visits despite the restaurant’s strategic location, unique waterfall concept, and active social media promotion. A quantitative explanatory approach was applied using a cross-sectional survey of 400 customers who had visited Flui Restaurant & Cafe Bogor. Data were collected through a structured questionnaire using a five-point Likert scale and analyzed using Structural Equation Modeling with LISREL 8.80. The results show that service quality has a positive and significant effect on customer satisfaction and revisit intention. Social media marketing activities also have a positive and significant effect on customer satisfaction and revisit intention. Furthermore, customer satisfaction significantly influences revisit intention and partially mediates the relationship between service quality and revisit intention, as well as between social media marketing activities and revisit intention. These findings indicate that increasing revisit intention requires an integrated strategy involving consistent service quality, interactive social media marketing, and customer satisfaction improvement
Abstract:This study aims to analyze the effect of service quality and sales promotion on consumer loyalty at Ihsan Mart in Kubu Raya. This study used an associative quantitative approach with 100 respondents selected through purposive…
osive sampling. Data were collected using questionnaires with a five-point Likert scale and analyzed using multiple linear regression with the assistance of SPSS. The results show that service quality and sales promotion have positive and significant effects on consumer loyalty, both partially and simultaneously. The regression results indicate that sales promotion has a greater contribution than service quality in increasing consumer loyalty. However, the coefficient of determination shows that service quality and sales promotion explain 16.3% of consumer loyalty, while the remaining 83.7% is influenced by other factors outside this study. These findings imply that local retail management should not only improve service quality and sales promotion programs, but also consider other factors such as customer satisfaction, product quality, price competitiveness, store atmosphere, and consumer trust to strengthen long-term consumer loyalty.
Abstract:This study examines the effect of inflation, interest rates (BI7DRR), and exchange rates (USD/IDR) on stock returns of PT Telkom Indonesia (Persero) Tbk., with the Jakarta Composite Index (IHSG) as an intervening variable.…
e. Using a quantitative explanatory research design, monthly secondary data spanning January 2016 to December 2025 (120 observations) were analysed using Pearson correlation and two-stage path analysis (OLS regression). Results indicate that inflation and exchange rates significantly influence IHSG, while the BI Rate does not. However, neither macroeconomic variables nor IHSG significantly affect Telkom's stock returns either directly or indirectly. The model explains only 2.7% of the variation in stock returns, suggesting that company-specific and sectoral factors dominate return determination. These findings imply that IHSG does not serve as an effective mediating channel between macroeconomic conditions and individual stock returns for Telkom. Investors in the telecommunications sector should prioritise fundamental and sectoral analysis over macroeconomic indicators when making portfolio decisions
Abstract:This study examines the effects of health, education, economic, and infrastructure expenditures, economic growth, investment, and the Labor Force Participation Rate (LFPR) on the Human Development Index (HDI) in Indonesia.…
a. It also compares the determinants of HDI between Western and Eastern Indonesia. Using a quantitative approach, the study applies panel data regression with the Common Effect Model and Ordinary Least Squares method. Secondary data from 2012–2021 were obtained from Statistics Indonesia, the Ministry of Finance, and other official institutions. The results show that all independent variables simultaneously have a significant effect on HDI. Partially, education expenditure, infrastructure expenditure, and investment have positive and significant effects, while health expenditure, economic expenditure, economic growth, and LFPR are statistically insignificant. Regional analysis reveals different determinants of HDI. In Western Indonesia, education expenditure, infrastructure expenditure, economic growth, and LFPR significantly affect HDI. In Eastern Indonesia, infrastructure expenditure, investment, and LFPR are significant determinants. These findings demonstrate that regional disparities in human development are associated with differences in economic capacity, infrastructure quality, investment distribution, connectivity, and development governance. Therefore, place-based development policies are required to improve the effectiveness and equity of human development, particularly in Eastern Indonesia.
Abstract:This study aims to analyze the simultaneous and partial effects of job satisfaction, employee loyalty, and work commitment on employee performance at PT Sulsel Citra Indonesia (Perseroda). This research adopts an associative…
tive quantitative approach. Data were collected through structured questionnaires distributed to 54 respondents drawn from a population of 114 permanent employees using simple random sampling. Multiple linear regression analysis was conducted using SPSS version 26. The finding that The F-test result (Fcount = 60.515 > Ftable = 2.196; sig. = 0.000) confirms that all three variables simultaneously exert a positive and significant effect on employee performance. Partially, job satisfaction (t = 3.485; sig. = 0.001) and work commitment (t = 11.685; sig. = 0.000) each have a positive and significant effect on employee performance, while employee loyalty (t = -3.080; sig. = 0.003) shows a negative and significant effect. The adjusted R² of 0.771 indicates that 77.1% of the variance in employee performance is explained by the three predictors. Work commitment emerged as the dominant predictor of employee performance, followed by job satisfaction. The negative effect of employee loyalty suggests that loyalty alone does not directly translate into higher performance unless it is accompanied by adequate motivation, job satisfaction, and organizational support. These findings are consistent with previous empirical studies conducted in the plantation and service sectors
Abstract:The transformation of the Islamic banking industry requires the integration of financial performance, customer trust, and customer loyalty as the foundation for institutional sustainability. This study aims to map the intellectual…
tellectual evolution of this field of study and identify dominant themes, development trends, and opportunities for research gaps in the international literature. The method employed is a bibliometric analysis based on a Systematic Literature Review (SLR) using the PRISMA procedure on Scopus articles from 2018 to 2025. From a selection process of 2,009 documents, the study identified 37 articles meeting the inclusion criteria, which were then analyzed using co-authorship, co-occurrence, network, overlay, and density visualizations. The results indicate that the themes of customer loyalty, service quality, customer satisfaction, and customer trust form the core of the intellectual structure with the highest connectivity, while the themes of financial performance, digital trust, banking mergers, and Sharia banking mergers remain in low-density areas, signaling opportunities for research development. The novelty map also reveals a shift in focus from traditional loyalty models toward digital banking, customer experience, and e-CRM. The novelty of this study lies in its proposal of a new research agenda model that integrates financial performance–customer trust–customer loyalty within the context of digital transformation and the consolidation of Sharia banks. Thus, it is hoped that this study can provide a conceptual foundation for future cross-national empirical research
Abstract:This study aims to examine the role of competition law in regulating corporate conduct, protecting consumers, and enhancing economic efficiency in contemporary market economies. Amid increasing market concentration, digital…
tal platform dominance, and the emergence of data-driven business models, competition law has become an essential regulatory instrument for ensuring fair competition, safeguarding consumer interests, and promoting sustainable economic development. This study employs a Systematic Literature Review (SLR) based on the PRISMA 2020 framework. Relevant literature was systematically collected from six major academic databases, namely Scopus, Web of Science, ScienceDirect, SpringerLink, Emerald Insight, and Taylor & Francis Online. The review process included identification, screening, eligibility assessment, and inclusion stages. A total of 78 peer-reviewed articles published between 2015 and 2025 were selected and analyzed using thematic synthesis techniques. The findings reveal that competition law performs four interconnected functions. First, it serves as a regulatory mechanism that shapes corporate behavior and prevents anticompetitive practices, including monopolization, cartel agreements, price-fixing, and abuse of dominant positions. Second, competition law enhances consumer welfare by promoting competitive prices, product quality, innovation, and consumer choice. Third, effective competition policy contributes to allocative, productive, and dynamic efficiency, thereby supporting long-term economic growth. Fourth, digital markets introduce new challenges associated with data concentration, platform dominance, network effects, and algorithmic pricing, requiring adaptive regulatory frameworks and strengthened institutional capacity.This study contributes to the literature by integrating Economic Efficiency Theory, Consumer Welfare Theory, Competition Policy Theory, and Regulatory Governance Theory into a comprehensive analytical framework that explains the relationship between competition law, corporate conduct regulation, consumer protection, and economic efficiency.The findings provide policy recommendations for competition authorities and governments, particularly in developing economies, regarding digital competition governance, institutional strengthening, cross-border enforcement cooperation, and data-driven market regulation.Unlike previous studies that focus on isolated dimensions of competition law, this research offers a holistic synthesis of legal, economic, consumer welfare, and governance perspectives. It further highlights how competition law can address emerging challenges in the digital economy while simultaneously promoting consumer protection and economic efficiency.
Abstract:This study analyzes the effect of Debt to Equity Ratio (DER), Return on Assets (ROA), and Asset Growth on Firm Value with Good Corporate Governance (GCG) as a moderating variable in industrial sector companies listed on…
the Indonesia Stock Exchange during the 2022–2024 period. The research method uses a quantitative associative approach with a sample of 65 companies and a total of 195 observations. The analysis technique used is Moderated Regression Analysis (MRA). The simultaneous test results show that DER, ROA, Asset Growth, GCG, and the moderating interaction variable have a significant effect on Firm Value with a significance value of 0.000 < 0.05. Partially, DER has a positive and significant effect on Firm Value, while ROA and Asset Growth do not have a significant effect on Firm Value. Good Corporate Governance has a positive and significant effect on Firm Value. Good Corporate Governance is able to moderate the effect of DER on Firm Value. Good Corporate Governance is not able to moderate ROA on Firm Value, and weakens the effect of Asset Growth on Firm Value
