Abstract

The accumulation of student databases can occur if students are unable to complete their studies, namely graduating at a predetermined time. Data mining techniques are often used to process student data so that they can produce predictions of student graduation in order to graduate at a predetermined time. One of the data mining techniques that is often used is the Support Vector Machine (SVM) algorithm. This study aims to analyze the performance of the SVM algorithm to produce a predictive model of student graduation in order to graduate at a predetermined time in the Public Health Study Program, Faculty of Public Health, Deli Husada Health Institute. The method used in this study is a linear SVM algorithm starting from data retrieval by selecting the attributes that will be used for the next stage, data processing consists of cleaning data whose contents do not exist and data transformation which is the determination of the category of each data, modeling is done with the SVM algorithm. from training data and testing and evaluation data to validate and measure the accuracy of the model. The test results with the amount of training data as much as 70% and testing data as much as 30% shows that the linear SVM algorithm provides an accuracy value of 90%

Abstract

This study presents a comprehensive analysis of the evolution of digital leadership in education, tracing its development from the initial concept of e-leadership to Leadership 4.0 amid the era of digital transformation and artificial intelligence (AI). "A selection of relevant scientific publications from the period of 2010–2025 was systematically analyzed using a Systematic Literature Review (SLR) approach were thematically analyzed to identify conceptual shifts, theoretical trends, practices, and implementation barriers. The findings reveal a paradigm transition from a technology-focused leadership to a strategic role emphasizing agility, data-driven innovation, and ethics. Modern digital leaders are no longer just technology managers but ecosystem orchestrators tasked with balancing technology, pedagogy, and equity to address infrastructural, capacity, and cultural challenges. Although theoretical frameworks like transformational and distributed leadership are widely used, longitudinal and comparative research remains limited. This review positions digital leadership as an adaptive, ethical, and systemic practice, proposing a future research agenda focused on theory integration, cultural diversification, human-centered ethics, and policy translation to build equitable and intelligent educational systems

Abstract

Effective information system design requires a clear and comprehensive understanding of the desired ideal system conditions in order to support organizational objectives. The TO-BE approach is a business process modeling method that describes future system conditions as a conceptual and strategic basis for improving existing AS-IS conditions. This study aims to analyze the effect of implementing the TO-BE approach in information system design on the clarity of system requirements, overall process efficiency, and the quality of system design outcomes. The research method used is descriptive-analytical research with a qualitative approach, employing data collection techniques such as literature review, direct observation, and in-depth analysis of system design documents. The results show that implementing the TO-BE approach in information system design provides a more structured and systematic overview of business processes, minimizes mismatches between system functionality and user needs, and improves the effectiveness and efficiency of business processes. Furthermore, the TO-BE approach assists system developers and analysts in designing system solutions that are aligned with organizational goals, operational requirements, and user expectations. Thus, implementing the TO-BE approach positively impacts the overall quality of information system design and is recommended as a critical and essential step in information system development initiatives.

Abstract

Perkembangan teknologi informasi mendorong meningkatnya kebutuhan akan sistem informasi yang andal dan sesuai dengan kebutuhan pengguna. Keberhasilan pengembangan sistem informasi sangat dipengaruhi oleh pemilihan model pengembangan perangkat lunak yang tepat. Salah satu model yang masih banyak digunakan hingga saat ini adalah model Waterfall. Penelitian ini bertujuan untuk menganalisis penerapan model Waterfall dalam pengembangan sistem informasi serta menilai efektivitasnya dalam menghasilkan sistem yang sesuai dengan kebutuhan pengguna. Metode penelitian yang digunakan adalah pendekatan kualitatif dengan studi literatur, yaitu mengkaji berbagai buku dan artikel jurnal yang relevan dan diterbitkan di atas tahun 2019. Hasil kajian menunjukkan bahwa model Waterfall efektif diterapkan pada proyek pengembangan sistem informasi dengan kebutuhan yang jelas, stabil, dan terdefinisi sejak tahap awal. Struktur tahapan yang sistematis serta dokumentasi yang lengkap membantu menjaga kesesuaian antara kebutuhan pengguna dan sistem yang dikembangkan. Namun demikian, keterbatasan fleksibilitas terhadap perubahan kebutuhan menjadi kelemahan utama model Waterfall, terutama pada proyek yang bersifat dinamis. Oleh karena itu, penerapan model Waterfall perlu disesuaikan dengan karakteristik proyek agar sistem informasi yang dihasilkan dapat memenuhi kebutuhan pengguna secara optimal. Kata kunci: model Waterfall, sistem informasi, pengembangan sistem, kebutuhan pengguna, studi literatur

Abstract

Safeguarding digital assets is a critical element in overseeing corporate information infrastructures, becoming vital within the financial services landscape, including private pawnshops. This research focuses on fortifying data protection at PT Budi Gadai Indonesia by adopting the performance-based COBIT 2019 system and evaluating its operational impact. Using a descriptive-qualitative methodology, the study examines security management practices and their integration with the DSS and EDM areas of the framework. Conducted as a longitudinal evaluation (2020–2025), the deployment followed a systematic multi-phase strategy. Empirical evidence indicates that integrating this governance model bolstered security through rigorous access monitoring, refined audit logs, and structured risk mitigation. Specifically, the activation of DSS05 and DSS06 protocols lowered breach vulnerabilities by 68% and ensured stricter regulatory adherence. Notably, the integrity maturity rating surged from 2.22 to 4.24, representing a 91% enhancement. These outcomes suggest that international security standards are instrumental in securing information systems within the private pawn brokerage sector.

Abstract

The purpose of this study is to evaluate the School Management Information System and student data governance at Medan 1 Public High School (SMAN 1 Medan) using the COBIT 2019 framework. The evaluation was conducted across three key domains: grade and NISN (National Student Identity Number) data integrity (DSS06), e-learning availability (DSS05), and student data security. A quantitative approach was employed, with data collected through questionnaires, interviews, and direct observation of operational systems. The survey participants consisted of 45 individuals, including the principal, vice principal, teachers, IT staff, and system administrators. The analysis indicated that SMAN 1 Medan's IT governance maturity was at "Level 2 (Managed)" with an average score of 2.45 out of 5. The scores by domain were 2.38 for DSS06 (Business Process Control Management), 2.52 for DSS05 (Service Request and Incident Management), and 2.45 for the Data Security domain. Key findings from the study included the identification of several areas requiring improvement: (1) insufficient documentation for grade and NISN data management procedures, (2) e-learning infrastructure limitations that caused periodic downtime, and (3) suboptimal implementation of student data security policies. The study offers strategic recommendations for raising IT governance maturity to "Level 3 (Established)" through the implementation of standard operating procedures (SOPs), infrastructure improvements, and strengthening of information security policies.
