academic English literacy among Indonesian undergraduates. Using a quantitative quasi-experimental design with a pre-test and post-test control group, 60 students were divided into experimental and control groups. Instruments included comprehension tests, learner autonomy questionnaires, and rubric-based writing assessments. Results showed significant improvements in the experimental group. Academic text comprehension increased, particularly in vocabulary mastery (+12%), rhetorical structures (+15%), and recognition of formal registers (+10%). Copilot usage positively predicted learner autonomy, with gains in goal-setting (+14%), strategy selection (+11%), and self-evaluation (+13%). Writing performance also improved, especially in coherence (+13%), argumentation (+16%), and adherence to conventions (+12%). The findings confirm Copilot’s role as both corrective aid and developmental partner, fostering academic literacy and learner autonomy. Implications suggest integrating AI tools into EFL curricula to strengthen academic discourse and independent learning.

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

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.

ucted using the financial ratios TATO, ROE, EPS, CR, DER, and DPR. The results show that UNVR and KLBF demonstrated high efficiency in asset management, while BBCA and BMRI exhibited strong profitability. JSMR had an aggressive capital structure but was supported by adequate liquidity. Meanwhile, UNVR and BBRI stood out for their generous dividend distribution policies. Stock valuation was carried out using two approaches: PER and PBV. Based on PER, nine issuers were classified as undervalued because their intrinsic values exceeded market prices, while two issuers (DSNG and SMGR) were considered overvalued. In contrast, the PBV approach indicated that ten issuers were overvalued, with only DSNG being undervalued. These differing results suggest that PER focuses more on a company’s earnings performance, whereas PBV emphasizes its book value. Therefore, stock investment assessment should be carried out comprehensively by considering more than one valuation method.
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.
