This study examines the influence of leverage, profitability, and capital structure on earnings management in consumer non-cyclicals companies listed on the Indonesia Stock Exchange (IDX) during the period 2019–2023. Earnings management has become a central issue in financial reporting, as it reflects managerial discretion in presenting financial information that may not fully align with the company’s actual economic condition. Understanding the determinants of earnings management is therefore essential to enhance transparency, credibility, and stakeholder trust in corporate financial reports. The research employed a quantitative approach using multiple linear regression analysis, with data processed through SPSS version 25. The sample consisted of 104 company-year observations, which were selected using purposive sampling techniques and subsequently refined through outlier testing to ensure data validity and reliability. The independent variables analyzed were leverage, profitability, and capital structure, while earnings management served as the dependent variable. The empirical findings demonstrate that leverage and profitability exert a significant influence on earnings management practices. Specifically, companies with higher leverage tend to engage in earnings management as a mechanism to meet financial obligations and reduce the risk of violating debt covenants. Similarly, higher profitability motivates managers to manipulate earnings in order to sustain investor confidence and maintain a favorable corporate image. In contrast, capital structure is found to have no significant effect on earnings management, indicating that financing decisions between debt and equity may not directly influence managerial behavior in financial reporting. These results highlight the importance of monitoring leverage and profitability indicators as potential predictors of earnings management. For corporate management, the findings suggest the need to implement stronger internal control systems and uphold ethical financial practices. For investors and regulators, the study provides useful insights into assessing company performance beyond reported earnings, thereby supporting more informed decision-making and promoting the integrity of capital markets.

Advancements in information technology have influenced changes in consumer behavior, particularly in making purchasing decisions, especially with the emergence of the Electronic Word of Mouth (EWOM) phenomenon on social media and e-commerce platforms. EWOM refers to the electronic dissemination of information or reviews about products, which many consumers rely on before deciding to purchase a product. This study aims to analyze how three main aspects of EWOM—intensity, Valence of Opinion, and content quality—affect purchasing decisions for Barenbliss lip cosmetic products in Bandar Lampung. This study uses a quantitative-descriptive approach, with data collected through a questionnaire distributed to consumers who have used Barenbliss products and have seen digital reviews about the product. The sample selected consists of consumers with direct experience with the product and who can provide insights into the influence of digital reviews on purchasing decisions. The data collected was analyzed using SPSS 25.0. The results show that all three independent variables—intensity, Valence of Opinion, and content quality—have a significant positive impact on purchasing decisions, either individually or collectively. All hypothesis tests showed significance values below 0.05, indicating that the hypotheses are accepted. These findings suggest that the more frequently consumers are exposed to product reviews, the higher the likelihood they will make a purchase. Positive reviews (Valence of Opinion) were found to enhance consumer trust in the product, while informative and high-quality content further strengthened the intention to purchase. Overall, this study emphasizes that EWOM plays a significant role in shaping consumer purchasing decisions. The intensity of reviews, positive Valence of Opinion, and content quality work together to increase the likelihood of purchasing Barenbliss products in Bandar Lampung.

In the digital age, consumer awareness of sustainable products has increased significantly. Recent research (2023-2025) shows that 84% of Indonesian consumers have used eco-friendly products, driven by a desire to preserve the earth. The purpose of this study is to analyze how digital information, particularly Electronic Word-of-Mouth (E-WOM), perceptions of sustainable packaging, and environmental concerns influence consumer perceptions and purchasing decisions in Indonesia. The proposed method is a quantitative approach using multiple linear regression analysis, preceded by classical assumption testing and instrument reliability testing. Key findings from the supporting literature indicate that E-WOM has a strong influence on purchase interest, even mediating the relationship between green marketing and purchase intention. In addition, product information transparency (ecological labels) is significant in increasing trust. The conclusion confirms that effective digital strategies must prioritize positive E-WOM communication and sustainability data transparency.

The importance of data mining in Indonesia is increasing along with the growth of big data in various strategic sectors. Data mining plays an important role in transforming complex data into useful information to support data-driven decision making, which is urgently needed in the face of competitive challenges and operational complexity. This research aims to examine the development of data mining techniques and applications in Indonesia over the last decade (2015-2024). Through a systematic literature review approach, data was collected from academic publications in SCOPUS indexed databases. From the initial 95 papers found, a further selection was made based on accessibility, title, and abstract until 64 papers were included in the article review. The results show that techniques such as K-Means, Naive Bayes, and Decision Tree are most commonly used. In the business sector, clustering through K-Means is widely applied for market segmentation and consumer pattern analysis. The healthcare sector mainly utilizes classification techniques, such as Naive Bayes and Decision Tree, for disease risk prediction and early diagnosis. Meanwhile, the education sector uses data mining to assess student performance and predict potential dropouts, assisting institutions in optimizing learning strategies.

The policy default case by PT Asuransi Jiwasraya caused widespread unrest among the public and became an important precedent in assessing the effectiveness of legal protection for consumers in the financial services sector, especially life insurance. This research aims to analyze the form of legal protection provided to consumers, identify the regulations governing it, and evaluate the role of the Financial Services Authority (OJK) in supervising and handling the default case. The method used is a normative juridical approach by analyzing laws and regulations, legal doctrines, and court decisions, and supported by literature reviews from various scientific journals. The results show that although the regulatory framework governing consumer protection in the insurance sector is quite complete, such as Law Number 40 of 2014 concerning Insurance and Law Number 8 of 1999 concerning Consumer Protection, its implementation is still weak. OJK's role as a supervisor has proven to be not optimal, both in early detection of Jiwasraya's financial crisis and in taking action against violations of the prudential principle by company management. The conclusion of this study states that legal protection of consumers in the Jiwasraya case has not been functionally effective, and needs to be strengthened through supervisory reform and regulatory improvement. This research is expected to contribute to the formulation of policies and the improvement of the consumer protection system in the future.  

This study aims to examine the influence of price and store atmosphere on repurchase decisions, with customer satisfaction as a moderating variable among Beocca Coffee consumers in Malang Regency. A quantitative explanatory approach was employed, involving 130 respondents selected through purposive sampling. Data were collected via an online questionnaire and analyzed using Partial Least Square–Structural Equation Modeling (PLS-SEM). The results show that price, store atmosphere, and customer satisfaction have a positive and significant effect on repurchase decisions. However, customer satisfaction was not proven to moderate the relationship between price and repurchase decisions, nor between store atmosphere and repurchase decisions. These findings indicate that price and store atmosphere influence repurchase decisions directly, regardless of customer satisfaction levels. The practical implication is that coffee shop managers should focus on offering competitive prices and creating a pleasant store atmosphere. Although customer satisfaction does not act as a moderator, it remains a crucial direct factor affecting loyalty. Future studies are encouraged to expand the research scope geographically and include additional variables such as customer loyalty, perceived quality, or digital marketing strategies to deepen the understanding of repurchase behavior in the local coffee shop industry.
