This study aims to analyze the development of regional financial performance and its effect on economic growth in Jambi Province during the 2019–2023 period. Regional financial performance is measured using the Regional Financial Independence Ratio and the Fiscal Decentralization Degree (FDD), while economic growth is proxied by Gross Regional Domestic Product (GRDP). This research employs a quantitative approach using secondary data obtained from the Central Statistics Agency (BPS), the Directorate General of Fiscal Balance (DJPK), and regional government financial reports covering 11 regencies/cities in Jambi Province. The analytical method applied is panel data regression using the Random Effect Model (REM). The results indicate that both regional financial performance and economic growth in Jambi Province experienced fluctuations throughout the study period. Partially, the Fiscal Decentralization Degree (FDD) has a positive and significant effect on GRDP, with a probability value of 0.0138. In contrast, the Regional Financial Independence Ratio does not have a significant effect on GRDP, as indicated by a probability value of 0.8843. Simultaneously, FDD and the Regional Financial Independence Ratio significantly affect GRDP, with an F-statistic probability value of 0.0390. The coefficient of determination (R²) is 0.1173, indicating that 11.73% of GRDP variation can be explained by the two variables, while the remaining 88.27% is influenced by other factors outside the research model. This study concludes that strengthening regional fiscal capacity through the optimization of local own-source revenue and fiscal decentralization policies is essential for promoting sustainable economic growth in Jambi Province.

Predictive maintenance (PdM) plays a crucial role in modern industrial systems by minimizing downtime, reducing maintenance costs, and optimizing asset performance. However, many predictive models operate as “black box” systems, limiting transparency and making it difficult for operators to interpret their outputs. This study aims to integrate Explainable Artificial Intelligence (XAI) techniques with Remaining Useful Life (RUL) prediction models to improve both accuracy and interpretability. Various machine learning and deep learning approaches, including Support Vector Machines (SVM), Random Forest (RF), XGBoost, Long Short-Term Memory (LSTM), and Convolutional Neural Networks (CNN), are employed to predict RUL using real-time sensor data from rotating machinery. XAI methods such as SHAP, LIME, and attention mechanisms are applied to provide human-understandable explanations of model predictions. The models are evaluated based on accuracy, Root Mean Square Error (RMSE), and interpretability scores. The results show that XAI-enhanced models outperform traditional approaches in predictive performance while offering greater transparency. These explanations help maintenance engineers better understand the factors influencing predictions, thereby improving decision-making and trust in the system. Nevertheless, the integration of XAI introduces additional computational complexity, which may pose challenges for large-scale industrial implementation. Overall, this study highlights the potential of combining XAI with RUL prediction to develop more reliable, transparent, and effective predictive maintenance solutions.

The study investigates the impact of governance on firm value, along with the moderating role of institutional ownership, among companies operating in the consumer cyclicals and consumer non-cyclicals sectors listed on the Indonesia Stock Exchange (IDX) over the 2021-2023 period. Drawing on a sample of 42 companies and 126 observations, a quantitative panel data approach was adopted, with data gathered through purposive sampling. The Bloomberg Governance Score was used to measure governance, Tobin's Q served as a proxy for firm value, institutional ownership was the moderating variable, and firm size, leverage, and profitability were included as control variables. Model selection was conducted using the Chow and Hausman Tests in EViews 14, which indicated that the Random Effects Model (REM) was the most suitable estimation approach. The findings reveal that governance does not exert a significant influence on firm value. Furthermore, institutional ownership is unable to strengthen the relationship between governance and firm value. These results suggest that ESG-based governance signals have not yet been optimally absorbed by investors in the Indonesian capital market; hence, reinforcing governance reporting standards and enhancing investor ESG literacy are considered essential steps toward integrating non-financial information into investment decision-making.

This study empirically investigates how the degree of transparency in sustainability reporting influences earnings management practices among listed companies in Indonesia's energy sector on the Indonesia Stock Exchange, covering the period from 2021 to 2024. Grounded in three theoretical perspectives Agency Theory, Stakeholder Theory, and Legitimacy Theory this study argues that when companies disclose their sustainability information more comprehensively, management's capacity to manipulate reported earnings becomes increasingly constrained, owing to reduced information asymmetry and heightened external scrutiny. The independent variable is measured through the Sustainability Reporting Disclosure Index (SRDI), constructed based on the GRI Standards 2021, while earnings management is proxied by the absolute value of discretionary accruals derived from the Modified Jones Model. Firm size and leverage are incorporated as control variables. Using purposive sampling, 32 companies were selected, generating a total of 128 observations. The data were analysed through panel data regression employing a Random Effects Model with White's cross-section robust standard errors. The results reveal that sustainability reporting transparency does not exert a statistically significant effect on earnings management. This finding suggests that, within Indonesia's energy sector, sustainability reporting tends to function more as a legitimacy-seeking tool rather than a genuine expression of corporate transparency. Firm size was found to have a significant negative effect on earnings management, whereas leverage did not demonstrate a meaningful influence. This study contributes to the growing body of literature examining the relationship between sustainability reporting and earnings management, with particular relevance to the energy sector in the Indonesian context.

This study examines the application of Transparent Artificial Intelligence (AI) for fraud detection in public welfare programs using publicly available administrative data. Persistent challenges in welfare governance such as misallocation, fraud, and data inaccuracy necessitate analytical frameworks that are both effective and explainable. The research aims to design and evaluate an interpretable anomaly detection system capable of identifying irregularities in welfare distribution while maintaining transparency and accountability. Methodologically, the study employs two unsupervised models Isolation Forest and Local Outlier Factor (LOF) to detect anomalies in sub-district-level welfare data, incorporating features such as population size, number of beneficiaries, and coverage ratio. An Explainable AI (XAI) framework integrating surrogate Random Forests, Permutation Feature Importance (PFI), and local linear surrogates (LIME-like) is applied to ensure interpretability of both global and local model behaviors. Findings reveal that receivers per 1000 population and percentage coverage are dominant determinants of anomaly scores. Fifteen administrative units were flagged for potential inconsistencies suggesting over- or under-reporting of beneficiaries. Cross-validation between IF and LOF models confirmed consistency in identifying anomalous regions. The integrated XAI explanations enhance transparency, enabling policymakers and auditors to trace the rationale behind detected anomalies. In conclusion, the proposed Transparent AI framework demonstrates that combining anomaly detection with interpretability tools can strengthen accountability and fairness in welfare administration. It offers a reproducible, ethical, and data-driven approach to social program monitoring, reinforcing public trust and supporting responsible AI governance.

This research benchmarks multiple machine learning (ML) algorithms for large-scale loan default prediction using a real-world dataset of 255,000 borrower records, where default cases represent only ~9–12% of total observations. The study addresses the persistent gap in comparative analyses of ML models that balance predictive accuracy, interpretability, and computational efficiency for credit risk assessment. Six algorithmic families were evaluated Logistic Regression, Random Forest, XGBoost, LightGBM, CatBoost, Artificial Neural Networks (ANN), and Stacked Ensemble—using standardized preprocessing, hybrid imbalance handling (SMOTE, class weighting, under-sampling), and comprehensive evaluation metrics (AUC, F1, Recall, Precision, PR-AUC, and Brier Score). Empirical results show Logistic Regression achieved the highest AUC of 0.732, outperforming nonlinear models under the baseline configuration, while LightGBM attained perfect recall (1.0) but low precision (0.116), indicating over-prediction of defaults. Gradient boosting models demonstrated robust calibration (Brier ≈ 0.114–0.116) and the best computational efficiency, with LightGBM showing the fastest training and lowest memory use. CatBoost exhibited strong recall but the slowest computation, and ANN underperformed on tabular data (AUC ≈ 0.56). The Stacked Ensemble delivered balanced results with AUC = 0.664 and improved overall stability. These findings confirm that boosting-based models, particularly LightGBM and CatBoost, offer superior scalability and calibration, whereas Logistic Regression remains a valuable interpretable baseline. The study concludes that effective default prediction requires integrating rebalancing, calibration, and threshold optimization to enhance recall and operational deployment reliability in large-scale credit ecosystems.

The development of Digital Marketing and Electronic Word of Mouth (eWOM) has encouraged hospitals to adopt digital communication strategies to attract patients’ visit intentions. However, in public hospitals, the effectiveness of these strategies in influencing patient behavior still requires empirical validation. This study aims to analyze the influence of Digital Marketing and eWOM on patient visit intention, with Brand Awareness as an intervening variable at RSUD Cengkareng.This research employed a quantitative approach with an explanatory design. Data were collected from November to December 2025 from 100 general outpatient respondents selected using the Slovin formula and a simple random sampling technique. The data were gathered through structured questionnaires and analyzed using Structural Equation Modeling (SEM) with AMOS software.The results show that Digital Marketing and eWOM have a positive and significant effect on Brand Awareness. Both variables also significantly influence patient visit intention, with eWOM demonstrating the strongest effect. These findings indicate that information shared through digital platforms and patient recommendations plays an important role in shaping potential patients’ decisions to visit the hospital. However, Brand Awareness does not have a significant effect on patient visit intention and does not mediate the relationship between Digital Marketing, eWOM, and visit intention. This suggests that, in the context of RSUD Cengkareng as a public hospital, patients’ visit decisions are more directly influenced by digital information exposure and the credibility of online recommendations rather than by brand recognition alone.

The research population included all tenth-grade students of SMA Negeri 3 Tarakan in the 2024/2025 academic year. The research sample consisted of two classes selected randomly: one experimental class receiving discovery learning with an aptitude treatment interaction strategy and one control class receiving conventional learning. The research instruments consisted of a test measuring mathematical concept understanding on trigonometry material and a self-efficacy questionnaire. The data obtained were tested for prerequisites through normality and homogeneity tests before being analyzed using inferential statistical tests in the form of an independent samples t-test with the assistance of SPSS software version 26.0. The research results show that the implementation of the discovery learning model with the aptitude-treatment interaction strategy has a significant impact on students' mathematical concept understanding and self-efficacy simultaneously, with a significance value of 0.006 < 0.05. Partially, this learning model has a significant effect on students' mathematical concept understanding, with a significance value of 0.018 < 0.05. However, the effect of the discovery learning model with the aptitude-treatment interaction strategy on students' self-efficacy is not statistically significant, as indicated by a significance value of 0.089 > 0.05, even though there is a tendency for increased self-efficacy among students participating in the experimental class learning. Nevertheless, the influence of the discovery learning model with the aptitude treatment interaction strategy on students' self-efficacy is not statistically significant in partial terms, although there is a tendency for an increase in self-efficacy among students participating in the experimental class. These findings suggest that the discovery learning model with the aptitude treatment interaction strategy is effective in improving students' understanding of mathematical concepts in trigonometry material and has the potential to support the development of self-efficacy in mathematics learning.
