Abstract

On-time student graduation is one of the important indicators in evaluating higher education performance. However, the classification of on-time graduation in academic data often faces the problem of imbalanced class distribution, which can affect the performance of machine learning models. This study aims to develop a classification model for student on-time graduation using the CatBoost algorithm optimized through Grid Search Cross-Validation within the Educational Data Mining framework. The research dataset consists of 951 students with a class imbalance ratio of 1.83:1. Imbalance handling was performed using the Synthetic Minority Oversampling Technique (SMOTE), while hyperparameter optimization was conducted using stratified 5-fold cross-validation with a total of 108 parameter combinations. The results show that the optimized CatBoost model achieved better performance than the default model, with an accuracy of 91.10 percent, a weighted F1-score of 91.20 percent, and a ROC-AUC of 96.09 percent, improving from the default model’s accuracy of 89.01 percent, weighted F1-score of 89.20 percent, and ROC-AUC of 95.39 percent. Feature importance analysis shows that accumulated credits and academic performance in the middle to final semesters are the most influential factors in the classification results. This study demonstrates that hyperparameter optimization plays an important role in improving CatBoost performance on academic data with imbalanced class distribution. The developed model represents classification based on students’ longitudinal academic records, rather than an early prediction system based on initial-semester data, because the features with the highest predictive contribution come from the middle to final semesters.

Abstract

This study aims to develop an integrated digital marketing governance model for products made by inmates in correctional institutions. The research addresses the lack of integration in the marketing activities of inmate-produced products, where product management, digital promotion, sales transactions, and activity reporting are largely performed through fragmented and manual processes. The study adopts the Design Science Research (DSR) methodology, encompassing the stages of system requirements identification, model design, system architecture development, business process visualization, and conceptual evaluation through expert review and focused group discussions. The proposed model integrates product management, digital promotion, sales transactions, activity documentation, digital monitoring, and institutional oversight into a unified digital marketing governance framework. The conceptual evaluation involved four experts, comprising two correctional rehabilitation officers and two vocational program managers, who confirmed that the proposed model adequately addresses the digital marketing management needs of correctional institutions. The findings further demonstrate that the use of social media, online marketplaces, and digital communication platforms can effectively support the marketing of inmate-produced products while maintaining appropriate institutional oversight and security controls. This study contributes by proposing an institutionally governed digital marketing model that can be implemented through a low-cost digital architecture, making it particularly suitable for organizations operating in environments with strict digital access restrictions.

Abstract

The Academic Information System (SIAKAD) is a core service that supports higher education operations and requires effective information technology (IT) governance to ensure regulatory compliance, data quality, risk management, and service continuity. This study aims to identify IT governance priorities for the STIE AMA Salatiga Academic Information System using the COBIT 2019 Design Factors before conducting a capability assessment. A qualitative research approach was employed, utilizing a structured COBIT 2019 assessment based on observations, interviews, and Design Factors questionnaires. The analysis evaluated the ten COBIT 2019 Design Factors to determine the importance scores of the 40 governance and management objectives. The results indicate that service stability orientation, regulatory compliance, risk management, and dependence on cloud/SaaS services collectively define eight priority objectives: MEA03, EDM03, APO12, APO14, DSS05, DSS02, APO08, and DSS04. The findings further reveal that, within a cloud/SaaS environment, IT governance priorities primarily focus on regulatory compliance, risk management, data governance, service security, external service provider management, and service continuity. The study demonstrates that the COBIT 2019 Design Factors provide an effective mechanism for identifying relevant governance and management objectives prior to capability assessment, thereby establishing a structured basis for prioritizing IT governance evaluation and improvement in accordance with organizational characteristics.

Abstract

The utilization of information technology (IT) in retail micro, small, and medium enterprises (SMEs) is essential for improving operational efficiency and service quality. However, limited resources and dependence on external vendors pose significant operational risks. Swalayan Pasar Pagi in Tegal utilizes a locally hosted Inti Accounting System supported by external technical services, making it vulnerable to system downtime and weak internal controls. This study aims to evaluate the governance of the system using the COBIT 2019 framework through an analysis of design factors and the governance system design workflow. The research adopts a qualitative descriptive approach, with data collected through semi-structured interviews, observations, and documentation. The results indicate that the supermarket’s strategy focuses on cost efficiency and improving customer service, with primary objectives including enhancing the quality of management information, optimizing business processes, and increasing operational efficiency. Critical risks identified include vendor dependency, reliance on local server infrastructure, and the absence of internal audits. COBIT 2019 mapping identifies BAI10, EDM05, APO14, and APO12 as priority governance and management objectives. The recommended improvements include the establishment of Service Level Agreements (SLAs), regular data backups, periodic system audits, and training for non-IT staff. This study provides practical contributions to strengthening IT governance in retail SMEs and extends the literature on the application of COBIT 2019 in small enterprises, which remain underexplored. The findings also demonstrate that adapting the COBIT 2019 framework is effective in enhancing operational efficiency and reducing IT-related risks in retail SMEs.

Abstract

This study aims to determine the effect of financial distress and regional independence on the probability of corruption in the local governments, of Indonesia. This study used panel data from local governments in Indonesia in 2012 and 2013 with 785 local governments. Data in 2012 and 2013 was used since the trial process for fraud cases takes a long time to get to the permanent legal power decision (inkracht). Data were analyzed using logistic regression analysis. The study results found that financial distress did not affect the probability of corruption. In contrast, regional independence positively affected the likelihood of corruption in the local governments, in Indonesia. If regional independence is high, then the probability of corruption in the local government is also high, and vice versa. The study findings were also robust in an independent analysis when the additional test was carried out. Empirically, this study found that the independence of funding sources, independence ratios to meet regional needs, and regional income could be used to detect corruption in Indonesian local governments. While the budget solvency ratio, financial performance ratio of budget, the financial performance ratio of fund equity, and regional financial efficiency could not. The pressure to commit corruption occurs because the region is in an independent state. Therefore, supervision of the implementation of fiscal decentralization needs to be done so that corruption does not happen.
