Abstract:Companies listed in the Jakarta Islamic Index 70 (JII70) provide a unique research context because they operate within an Islamic capital market framework that applies sharia screening criteria and financial requirements.…
. Despite being guided by the same sharia principles and regulatory environment, JII70 companies still show variations in financial performance. Although previous research has examined the factors that affect financial performance, empirical evidence regarding the influence of efficiency, market ratios, liquidity, and leverage still shows inconsistent results, particularly in companies that comply with sharia principles. Therefore, this study aims to analyze the influence of efficiency, market ratio, liquidity, and leverage on the financial performance of companies listed on JII70 by using Return on Assets (ROA) as a performance indicator. This study uses a quantitative approach by utilizing secondary data obtained from the annual reports of 57 non-financial companies during the period 2021–2025, resulting in 285 company-year observations. Panel data regression analysis was performed using the Fixed Effects model with Driscoll–Kraay error standard to overcome the problems of heteroscedasticity and autocorrelation. The results show that efficiency measured by Total Asset Turnover (TATO) and market ratio measured by Price-to-Book Value (PBV) have a positive and significant effect on financial performance. Meanwhile, liquidity measured by Current Ratio (CR) and leverage measured by Debt-to-Asset Ratio (DAR) have a positive but not statistically significant effect on financial performance. The findings of this study support the Signaling Theory by showing that efficiency and market ratio provide stronger signals regarding company quality and financial performance in the context of the Islamic capital market in Indonesia. These findings provide practical implications for managers in improving company performance as well as for investors in making more informed investment decisions
Abstract:This study aims to analyze stock market reactions to Cum-Ex Dividend announcements for companies listed on the Indonesia Stock Exchange (IDX) in 2024. Market reactions were measured through abnormal returns and stock trading…
ding volume before and after Cum-Ex Dividend announcements. This study was motivated by differences in investor behavior in responding to dividend distribution information, which is regarded as a positive signal for the market. The research employed a comparative quantitative method with an event study approach. The sampling technique used was purposive sampling. Secondary data were obtained from the Indonesia Stock Exchange, comprising a sample of 88 issuers that distributed cash dividends. Research variables consisted of stock prices and stock trading volume. Data analysis was performed using dummy regression and the Wilcoxon Signed Rank Test with EViews 12 software. The results showed that the majority of issuers (81.82%) experienced significant market reactions to the Cum-Ex Dividend announcement. A total of 56.82% of issuers showed significant negative reactions consistent with the dividend drop theory, while 25% showed significant positive reactions, indicating that investors viewed dividends as a positive signal for company prospects. Meanwhile, 18.18% of issuers showed no significant reaction to dividend announcements. This study demonstrates that Cum-Ex Dividend announcements affect abnormal returns and stock trading volume, thus providing a basis for investor consideration in making investment decisions in the capital market.
Abstract:This study analyzes the dividend policy of PT Telkom Indonesia (Persero) Tbk (TLKM) during the 2020–2025 period using a quantitative descriptive approach and a longitudinal case study based on secondary data from audited…
ed financial reports. The variables analyzed include Dividend Per Share (DPS), Earnings Per Share (EPS), Dividend Payout Ratio (DPR), Dividend Yield, and Free Cash Flow (FCF), with trend analysis using the Compound Annual Growth Rate (CAGR). The results show that DPS grows 6.05% per year, higher than EPS of 1.87%, resulting in DPR increasing from 80.00% to 93.95% in 2024. Nevertheless, strong and stable operating cash flow ensures that dividends remain supported by FCF, so there is no indication of financial distress. However, the increasing FCF-to-dividend ratio indicates the company's increasingly limited reinvestment space. The decline in net profit of 20.48% in 2025 also increases the risk of dividend policy sustainability. Furthermore, the increase in dividend yield was more influenced by stock price declines than dividend growth. This finding suggests that SOE dividend stability reflects not only fundamental performance but also institutional pressure from the government as the controlling shareholder, supporting the relevance of Agency Theory and Catering Theory in explaining dividend policy of state-owned enterprises in emerging markets
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 develops a practical framework for evaluating AI-generated brand visuals in a marketing communication context. Using a qualitative case study of an Indonesian sustainable startup (I-NewBee), the research employs…
ys photo-elicitation interviews to compare consumer evaluations of brand assets generated by three text-to-image tools (Midjourney, Neural Love AI, and Leonardo AI). Twelve target-market participants assessed anonymized visual sets (A/B/C) produced under a standardized prompt structure, using a semi-structured protocol informed by attention-stage cues from the AISAS model. Expert input from a visual communication design practitioner was used to triangulate judgments on visual quality and brand fit. Data were analyzed through iterative coding and thematic synthesis to identify recurring evaluation dimensions and decision cues. The findings suggest that perceived brand fit is shaped by visual realism, compositional clarity, brand-consistent signals, and message interpretability, while prompt ambiguity and inconsistent visual cues reduce credibility. The paper contributes an actionable evaluation framework expressed as evaluation dimensions and prompt-design considerations for startups seeking to deploy generative AI responsibly in brand communication
Abstract:This study aims to analyze the effect of Human Resource Accounting (HRAC) disclosure on firm value, with financial performance as a mediating variable. This quantitative study uses secondary data in the form of annual reports…
ports and sustainability reports from 14 companies during the 2020–2024 period, with a total of 70 observations. HRAC disclosure is measured using the Human Resource Disclosure Index through a content analysis approach. Firm value is proxied by Net Asset Value (NAV) transformed into the natural logarithm, while financial performance is measured using ROA. Data analysis was performed using path analysis with SPSS software, and the Sobel test to examine the role of financial performance as a mediating variable. The results show that HRAC disclosure affects firm financial performance, but does not directly affect firm value. Financial performance is proven to affect firm value in a negative direction. The results of the Sobel test indicate that financial performance plays a significant role as a mediating variable in the relationship between HRAC disclosure and firm value. These findings indicate that HRAC disclosure affects firm value indirectly through financial performance. ASDM disclosure functions as supporting information and additional signals for investors, but is not yet able to become the main determinant in the direct formation of company value.
Abstract:The increased integration of operational technology (OT), Internet of Things (IoT), and business IT systems has allowed sophisticated attackers to circumvent isolated security features and launch cross-platform assaults.…
Current fragmented techniques, with discrete detectors monitoring Modbus, Kubernetes, MQTT, or other domain-specific protocols, cannot handle cross-system risks. These methodologies overlook 68% of multi-vector marketing that uses both physical and digital channels. This study introduces a transfer learning architecture to integrate detection capabilities by correlating threats across protocols, devices, and settings. The architecture generates a unified feature space that extracts behavioral semantics from industrial control system logs, cloud telemetry, network traffic, and device-level signals to produce protocol-agnostic threat representations. Adversarial domain adaptation and semantic graph embeddings enable cross-domain knowledge transfer with minimum retraining. Security teams may now discover kill chains like infected cloud containers preceding illegal PLC command execution every 23 minutes. Validated against real-world attack datasets from water treatment facilities (OT) and cloud infrastructure (IT), the system achieved 93.4% cross-platform attack recall, a 41.3 percentage point improvement over prior methodologies. It reduced OT data labeling by 89% and false positives by 93.5%. This paradigm shift transforms threat correlation from a reactive, domain-specific process to adaptive intelligence, boosting resilience for critical infrastructure, industrial ecosystems, and smart environments facing cyber-physical hazards. The framework's practical validation in energy, industry, and vital infrastructure shows its importance in protecting an increasingly linked world.
Abstract:This study investigates the role of acquisition premiums in mergers and acquisitions (M&A) and their impact on shareholder wealth, focusing on five major Indian deals in pharmaceuticals, retail, banking, steel, and renewable…
able energy sectors. Potential synergies often justify acquisition premiums ranging from approximately 15% to 40% above target companies’ market values. However, market responses suggest that such premiums may not consistently result in value creation for acquiring firms' shareholders. Empirical findings reveal mixed outcomes: Sun Pharma’s acquisition of Ranbaxy led to a 9.8% share price increase within five days, while Tata Steel’s high-premium acquisition of Bhushan Steel saw only a 1.7% gain. In contrast, deals like Reliance–Future Retail and Tata Power–Welspun Power showed minimal or negative returns, despite sizable premiums. These patterns indicate that premium size alone is not a reliable predictor of post-deal shareholder wealth creation. The study concludes that M&A success depends more on strategic fit, market timing, and sectoral dynamics than on the premium offered. This analysis contributes to the broader M&A discourse by offering evidence-based insights into how premium valuations can either maximise or dilute shareholder value, aiding investors, corporate strategists, and policy analysts in deal assessment
Abstract:Signal interference or noise is one of the main problems in data transmission that can reduce information quality in both analog and digital systems. This study aims to visually analyze the effects of noise using audio software.…
oftware. The method used is simulation-based, where a pure signal is used as an initial reference before being subjected to various levels of interference. The analysis results show that in analog signals, noise causes permanent waveform distortion that is difficult to recover. In contrast, digital signals tend to maintain data integrity as long as the interference does not exceed a certain threshold. These differences in signal characteristics can be visually observed through waveform displays in the software. The results indicate that digital systems have advantages in maintaining signal quality in noisy environments and have the potential to be used as educational media for basic telecommunication and signal processing studies.
Abstract:Stock prices represent the market’s consensus regarding the fair value of a business entity, formed through a rational assessment of both financial and non-financial information. Within the frameworks of signaling theory…
ry and market efficiency, financial ratios serve as fundamental indicators reflecting a company's ability to generate profit, manage assets, and maintain short-term liquidity stability. When the market faces systemic disruptions, such as the COVID-19 pandemic, and transitions toward post-pandemic normalization, investor sensitivity to internal indicators tends to increase due to heightened external uncertainty. Consequently, a deep understanding of the internal determinants of stock prices becomes increasingly critical for data-driven investment decision-making. This study aims to empirically examine the effect of the Current Ratio (CR), Return on Assets (ROA), and Total Asset Turnover (TATO) on stock prices, both partially and simultaneously, in companies listed on the Indonesia Stock Exchange (IDX) during the 2020-2024 period. A quantitative approach was employed, using a descriptive-verificative design and secondary data drawn from audited financial statements and annual closing stock prices. The sample consisted of 91 companies selected through purposive sampling, and the data were analyzed using multiple linear regression with SPSS version 27. The analysis results indicate that all three independent variables have a positive and significant impact on stock prices, both individually and collectively. This study contributes to the capital market literature by highlighting the relevance of financial ratios in explaining stock price fluctuations in the post-pandemic period, a topic that remains underexplored in the context of developing countries.
