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 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 aims to analyze the influence of Price and Social Media Marketing on the Decision to Use GrabFood in Pontianak City. This study employed an associative quantitative approach. The sample consisted of 100 respondents…
dents who were residents of Pontianak City, owned the Grab application, and had used GrabFood services. The main data were collected through questionnaires using a 5-point Likert scale, while observation, interviews, and secondary data were used as supporting data. The data were analyzed using multiple linear regression, supported by validity tests, reliability tests, classical assumption tests, correlation coefficient analysis, coefficient of determination, and hypothesis testing through t-tests and F-tests. The results show that all research instruments were valid and reliable. Partially, Price has a positive and significant effect on the Decision to Use, with a t-value of 4.069 and a significance value of 0.000. Social Media Marketing also has a positive and significant effect on the Decision to Use, with a t-value of 3.946 and a significance value of 0.000. Simultaneously, Price and Social Media Marketing have a significant effect on the Decision to Use, with an F-value of 28.950 and a significance value of 0.000. The coefficient of determination (R²) of 0.374 indicates that 37.4% of the Decision to Use GrabFood can be explained by Price and Social Media Marketing, while the remaining 62.6% is influenced by other factors outside this study.
Abstract:This study examines the reaction of the Indonesian capital market to the escalation of the Iran conflict in 2026 using an event study approach focusing on energy sector firms listed on the Indonesia Stock Exchange. Market…
t reactions are measured using Average Abnormal Return (AAR) and Trading Volume Activity (TVA). The observation period includes an 11-day event window (t−5 to t+5) and a 100-day estimation period. Statistical tests employed include the Shapiro–Wilk normality test, one-sample t-test, paired sample t-test, and Wilcoxon Signed Rank Test.
The findings indicate that abnormal returns are only significant around the event date but do not differ significantly between pre- and post-event periods. In contrast, trading volume activity shows consistent and significant changes. These results suggest that geopolitical conflict information is more strongly reflected in trading behavior than in price adjustments. This study contributes to the literature by providing sector-specific evidence from an emerging market and highlighting behavioral market responses.
Abstract:This study aims to analyze and compare the financial performance of PT Indofood CBP Sukses Makmur Tbk (ICBP) and PT Mayora Indah Tbk (MYOR), two leading companies in the food and beverage subsector listed on the Indonesia…
a Stock Exchange. This research employs a quantitative approach with a descriptive comparative method through financial ratio analysis, including Earnings Per Share (EPS), Price Earnings Ratio (PER), Price to Book Value (PBV), Return on Equity (ROE), Debt to Equity Ratio (DER), and Dividend Yield (DY) for the 2019–2023 period. The study uses secondary data obtained from annual financial reports and the official website of the Indonesia Stock Exchange. The results indicate that PT Indofood CBP demonstrates more stable and efficient financial performance than PT Mayora Indah, particularly in profitability and capital efficiency ratios. Meanwhile, PT Mayora Indah shows promising growth potential but tends to experience fluctuations due to high operating costs and aggressive expansion strategies. The managerial implication emphasizes the importance of balancing operational efficiency and growth strategies to enhance corporate value and long-term investment attractiveness.
Abstract:This study explored how cost structure, land productivity, and price efficiency shape the income of micro scale shallot farmers in Brebes Regency based on farmers' reported financial experiences and informants' financial…
narratives. Using an exploratory qualitative approach, data were collected from five shallot farmers, one agricultural extension officer, and one farmer group leader through semi-structured interviews, non-participant observation, and documentation. The data were analyzed through thematic analysis supported by source and technique triangulation. The findings show that reported income is highly vulnerable to variable production costs, particularly labor, seed, and pesticides. Land productivity is closely related to land ownership status and farming scale, while price efficiency is constrained by farmers' weak bargaining position and dependence on intermediaries. Farmers apply adaptive strategies such as delaying sales, drying harvested shallots, and converting part of the harvest into seed stock. However, these strategies are limited by liquidity needs, storage capacity, product quality, and market uncertainty. The study concludes that improving farmers' income stability requires integrated cost control, asset productivity, price information access, post-harvest support, and stronger farmer institutions.
Abstract:This study aims to analyze the factors that affect rice consumption in South Sulawesi Province using a panel data approach for 2018–2024. The dependent variables used are rice consumption (tons), while the independent variables…
variables include per capita income, household size, rice production, human development index (HDI), and percentage of poor population. The analysis was performed with a panel data regression model using R software, with a series of model specification tests including the Chow test, the Hausman test, and the Lagrange Multiplier (LM) test. The best model obtained is the Fixed Effect Model (FEM). Partially, the variables of household size and rice production had a significant negative effect on rice consumption, while HDI had a significant positive effect. The variables of per capita income and poverty level have a negative but not significant effect. These results indicate that rice consumption in South Sulawesi is more influenced by social aspects and quality of life than purely economic factors. These findings affirm the importance of food security policies that focus on improving human development, rice distribution efficiency, and strengthening social protection programs to maintain the stability of household food consumption.
Abstract:This study examines the rapid expansion of the coffee shop industry in Makassar City as a phenomenon that creates not only economic opportunities but also increasing competitive saturation. As coffee shops in Makassar have…
ve developed beyond places of beverage consumption into urban social spaces linked to lifestyle, sociability, symbolic visibility, and identity formation, competition has become denser and more complex. The study aims to gain an in-depth understanding of how coffee shop owners and managers experience, interpret, and respond to this increasingly crowded market. Using a qualitative phenomenological approach, the research employed in-depth semi-structured interviews with business actors involved in strategic and operational decision-making, supported by contextual observation and business-related documents. The findings reveal five main themes: market growth is experienced as both opportunity and pressure; similarity among coffee shops increases vulnerability and reduces perceived distinctiveness; entrepreneurs rely on continuous adaptation rather than fixed strategies; business sustainability is understood as stability, relevance, and survival rather than expansion alone; and competition is shaped not only by product and price, but also by ambience, visibility, symbolic value, and lifestyle alignment.
Abstract:This study investigates factors driving purchase intention toward reject fashion products at factory outlets in Makassar, Indonesia. Reject products garments that fail manufacturer quality control standards but are sold…
legally at discounted prices represent an underexplored segment of circular fashion consumption. Drawing on the Theory of Planned Behavior and the Value-Based Adoption Model, this study tests a structural model in which four antecedents defect transparency, price perception, environmental consciousness, and store reputation influence purchase intention through the mediating role of perceived value. A quantitative survey was conducted with 250 consumers who visited factory outlets in Makassar. Data were analyzed using PLS-SEM via SmartPLS 4.0. Common Method Bias was confirmed absent using Harman's Single Factor Test and Full Collinearity VIF. Results indicate that all four antecedents positively influence perceived value, which strongly predicts purchase intention. Price perception is the dominant driver, followed by store reputation, environmental consciousness, and defect transparency. Perceived value fully mediates the effect of defect transparency and partially mediates the remaining three antecedents. These findings contribute to circular fashion consumer behavior literature and offer practical guidance for factory outlet operators in Eastern Indonesia.
Abstract:This study aims to analyze the influence of international prices, the rupiah–rupee exchange rate, non-tariff measures, and India’s import volume on the export value of Indonesian cloves to India. The research utilizes secondary…
s secondary data for the period 2015–2024. The analytical method employed is the Autoregressive Distributed Lag (ARDL) model to examine both short-run and long-run relationships, complemented by stationarity tests, cointegration tests, ECM estimation, and diagnostic and stability tests. The results show that international prices have a positive and significant effect on Indonesia’s clove export value, consistent with export-supply theory which states that higher global prices increase export incentives. The rupiah–rupee exchange rate displays a positive but insignificant relationship, indicating that exchange rate volatility is not sufficiently strong to influence changes in export value. Non-tariff measures, including SPS and TBT standards, are found to have a significant effect, reflecting the role of regulations in increasing compliance costs while simultaneously enhancing Indian consumer confidence in the quality of Indonesian cloves. India’s import volume also has a significant influence, showing that India’s domestic demand remains a major driver of Indonesia’s export value during the study period. This study is expected to provide insights for policymakers and industry players in strengthening trade strategies, particularly in enhancing the competitiveness of Indonesian clove exports through quality improvements, exchange rate stability, and compliance with non-tariff standards.
