Abstract

Digital transformation in the education sector has accelerated the growth of internet-based learning platforms that offer learners greater flexibility in accessing educational content. Among the various foreign language programs available online, Japanese language courses have gained considerable popularity due to their ability to provide unrestricted learning access regardless of location or time. However, course providers frequently encounter significant data governance challenges, including inconsistent record-keeping, data duplication, and the fragmentation of learner information, class schedules, payment transactions, attendance records, assessment results, and certificate issuance across disconnected systems. These issues impede efficient data retrieval and reporting, while reliance on manual recording processes raises the risk of errors and delays. This study focuses on constructing a database architecture for an online Japanese language course information system, with the primary objective of achieving data consolidation and enhancing the quality of operational information management. The modeling approach encompasses three stages: entity mapping through an Entity Relationship Diagram (ERD), conceptual structuring via a Conceptual Data Model (CDM), and physical implementation using a Physical Data Model (PDM), complemented by a visual monitoring dashboard design for administrators. The findings demonstrate that a well-structured and integrated database design successfully consolidates all operational course data into a single centralized repository, substantially reduces data duplication, and streamlines the processes of management, visual monitoring, and information reporting within the online Japanese language course platform.

Abstract

Reda Printing is a printing business that still relies on manual recording for raw material inventory and operational transactions. This condition causes various issues, such as stock mismatches, sudden depletion of production materials, and the absence of a structured transaction track record, which ultimately burdens the management that relies heavily on a single administrator. This study presents the design of an integrated relational database system to address these problems. The design was carried out through three main stages: Entity Relationship Diagram (ERD) for logical modeling, Conceptual Data Model (CDM) as a conceptual representation, and Physical Data Model (PDM) for technical implementation. This system integrates five core entities—Barang, Supplier, Transaksi_Masuk, Order, and Detail_Order—which are implemented into MySQL. The added value of this design is the application of database-level automation using Triggers and Views, which function to update stock automatically and provide early warnings (smart alerts) when stock reaches its minimum limit. The results of this database design are expected to serve as the foundation for developing a reliable, accurate, and efficient operational information system to support Reda Printing's productivity.

Abstract

Manual management of boarding houses remains a widespread problem faced by many boarding house owners in Indonesia. Various issues such as errors in recording tenant data, unmonitored late rent payments, difficulties in monitoring room status, and undocumented facility complaint communications present real challenges in conventional boarding house management. This study aims to design and model a database for the Smart Kos Information System as an integrated digital solution. The design was carried out using Entity Relationship Diagram (ERD), Conceptual Data Model (CDM), and Physical Data Model (PDM) approaches to produce a structured and consistent database model. The designed entities cover tenant data, rooms, rent payments, and facility damage reports.

Abstract

The development of digital-based transportation technology demands a fast, accurate, and environmentally friendly data management system, particularly in electric motorcycle rental services. However, the complexity of managing operational data regarding fleets, battery conditions, and payment transactions often triggers risks of data redundancy and slow application performance if not supported by a robust database structure. This study aims to design a structured and efficient database architecture for the Electric Motorcycle Rental Information System. The research method was carried out progressively through data modeling phases, including Entity Relationship Diagram (ERD), Conceptual Data Model (CDM), and Physical Data Model (PDM). The results successfully mapped five core system entities: Pelanggan (Customer), Motor_Listrik (Electric Motorcycle), Stasiun (Station), Penyewaan (Rental), and Pembayaran (Payment), which are fully integrated through One-to-Many and One-to-One cardinality rules. The transformation from CDM to PDM generated a production-ready physical database blueprint with specific data types and proper implementation of Primary Key and Foreign Key mechanisms. In conclusion, this database design successfully creates a ready-to-use physical database schema capable of maintaining data integrity and preventing data redundancy to support efficient rental system operations.

Abstract

Digital transformation is Indonesia's principal national development strategy, pursued through the Making Indonesia 4.0 roadmap (2018) and the Indonesia Digital Roadmap 2021–2024. IT governance nevertheless confronts policy fragmentation, cyber vulnerability, and access disparities that threaten Indonesia's ambition of becoming one of the world's ten largest digital economies by 2030. This study conducts a systematic literature review following PRISMA 2020 guidelines, screening 1,248 initial articles in stages, narrowing to 456 after title and abstract screening and finally to 20 articles after full-text review, drawn from six major databases covering 2021–2025. The process identified five COBIT 2019 domains, with risk management (15 of 20 articles; 75%) and strategic alignment (14 of 20 articles; 68%) as the highest priorities, while performance measurement remained the weakest dimension. Thematic analysis using NVivo 14 yielded 22 major themes and informed the Indonesian IT Governance Index (IITGI), an initial score of 0.68 combining 38 OECD Digital Government Index indicators with 10 Indonesia-specific contextual indicators covering disaster resilience and sharia-economy inclusiveness. Indonesia falls outside the coverage of the OECD Digital Government Index and cannot be benchmarked directly against member countries; this limitation is itself part of the rationale for developing the IITGI. The findings recommend establishing a National IT Governance Council, a civilian national cyber security coordination body, and a real-time performance dashboard. The theoretical contribution lies in mapping the five COBIT domains and the resulting IITGI score onto Fountain's Technology Enactment Framework, grounding the framework's adaptation in empirical findings. This is translated into a 2026–2028 roadmap for the Ministry of Communication and Digital Affairs aimed at inclusive and sustainable digital transformation.
