Abstract

There are numerous frameworks that can be utilized to develop information technology governance when examining corporate governance. COBIT is an auditing framework that auditors use to control and manage IT governance. PT. XYZ is a newcomer in the paint and coating production industry in Indonesia, and to compete with competitors and accommodate corporate goals, a design in IT Governance is required to determine what must be changed. The research aimed to provide an IT governance design that tailored based on what the company needs. The governance design is compiled by using the latest COBIT 2019 framework, which involved interview and quantification of each Design Factor values from the interview. We conducted interviews with prominent IT personnel within the company using the COBIT 2019 framework Design Factor (DF), which includes: enterprise strategy, enterprise goals, risk profile, and I&T related issues, threat landscape, compliance requirement, role of IT, model of IT, and finally IT implementation methods. The results suggest that five core models, including EDM05, APO06, APO14, MEA03, and MEA04, are advised to have a competency level of 2. There is one core model for which a skill level of 3 is indicated, which is BAI09. This study is only concerned with developing an IT governance design; there is no evaluation of the core model or methodology.

Abstract

Effective information technology governance (ITG) is vital for managing risks and ensuring proper oversight of IT in government organizations and enterprises. However, many organizations struggle with implementing effective ITG strategies, resulting in a higher likelihood of cybersecurity breaches, operational inefficiencies, and financial losses. This study addresses the urgency of improving ITG by assessing the capability level of ITG within the Ministry of Communication and Information Technology (KOMINFO) in Bitung, North Sulawesi, using the widely recognized COBIT 2019 framework. By conducting interviews with key IT personnel, the study quantifies the capability level of eleven core models and highlights areas that require improvement. The results underscore the critical importance of designing and implementing effective IT governance to mitigate risks and enhance IT oversight in government organizations and enterprises. The study's findings can serve as a foundation for future efforts to improve IT governance in KOMINFO and other organizations, ultimately contributing to a safer and more secure IT environment.

Abstract

The main purpose of this research is to create a predictive model of the ARIMA method on the daily stock price of PT. Garuda Indonesia, Tbk during the Covid-19 pandemic. This study uses daily secondary data from April 22, 2019, to April 20, 2020. The results of research using the ARIMA model shows that data from April 22, 2019, to April 20, 2020, can be used to predict stock closing prices from April 21, 2020, to July 13, 2020. The ARIMA model obtained the results of daily stock price predictions of PT. Garuda Indonesia, Tbk on the Indonesia Stock Exchange from 21 April 2020 to 13 July 2020 tend to experience a decline. This is presumably because investors tend to hold back their capital due to the government's prohibition on going home, which resulted in the cessation of operations in the aviation sector. Keywords: Covid-19, Garuda Indonesia, stock price, ARIMA method.

Abstract

Information Technology (IT) governance is crucial for the success of companies in the current digital era. PT. Bitung Branch Fisheries, which operates in the fisheries sector in the Bitung area, faces challenges in effective IT management and governance. Adopting the COBIT 2019 framework, the company hopes to improve operational efficiency, reduce security risks, and ensure regulatory compliance. This research aims to explore the implementation of COBIT 2019 at PT. Bitung branch fisheries, identifying problems and potential improvements, as well as the impact on IT performance and governance. Focus on PT's unique context. The Bitung branch fisheries differentiate it from previous studies, hoping that the results will benefit companies and the IT governance community. Through a comprehensive literature review and research methodology, we analyze the design factors influencing IT governance and COBIT 2019 implementation. The results highlight APO04 as a priority object, indicating the company's attention to IT innovation. However, gaps were found in the current level of capability. We recommend strengthening the implementation of APO04, increasing managerial capabilities, and strategic collaboration to improve IT governance and innovation at the PT. Bitung branch of fisheries. In conclusion, this research provides valuable insights for companies and the IT governance community in implementing COBIT 2019 to improve performance and compliance in the ever-evolving digital era.

Abstract

Untuk mencapai tujuan finansial inklusi, yaitu meningkatkan pertumbuhan ekonomi dan kesejahteraan masyarakat, sebagian besar dimungkinkan oleh keuangan digital. Dengan meningkatnya perdagangan elektronik (e-commerce) dan teknologi finansial (fintech), pembayaran digital-salah satu komponen utama keuangan digital-menjadi semakin penting. Selain keuntungan-keuntungan tersebut, terdapat kekhawatiran bahwa keuangan digital dapat memperburuk risiko sistemik dan merusak stabilitas sistem keuangan. Tujuan dari penelitian ini adalah untuk memastikan bagaimana variabel-variabel risiko berhubungan dengan stabilitas keuangan dan hubungan keuangan digital. Selama sepuluh tahun (2010 hingga 2019), 120 sampel data panel digunakan dalam penelitian ini dengan menggunakan Model Regresi Linier Berganda dan Moderating Regression Analysis (MRA). Peningkatan risiko sistematis akan mengurangi efek menguntungkan dari keuangan digital terhadap stabilitas keuangan, karena hasil penelitian menunjukkan bahwa risiko pasar dapat mengurangi manfaat keuangan digital terhadap stabilitas keuangan.Kata kunci: Keuangan Digital, Pembayaran Digital, Risiko Sistematis, Stabilitas Keuangan, Inklusi Keuangan

Abstract

The rapid development of Information Technology (IT) has made IT governance essential for organizations to align business objectives, manage risks, and optimize resources. PT PLN (Persero) Unit Induk Wilayah Suluttenggo, a key player in electricity distribution in North Sulawesi, Gorontalo, and Central Sulawesi, requires a structured IT governance framework to ensure operational efficiency and compliance. This study evaluates the organization's IT governance maturity using the COBIT 2019 framework, focusing on its Design Factors and Governance Objectives. The research employs a structured methodology, starting with problem identification, a literature review, and the selection of relevant COBIT 2019 domains. Data collection is conducted through structured interviews using the COBIT 2019 Design Toolkit, analyzing ten key Design Factors, including Enterprise Strategy, Risk Profile, IT-related issues, and Compliance Requirements. The findings indicate that PT PLN prioritizes customer service, digital transformation, and regulatory compliance while facing challenges in IT risk management, project execution, and IT investment optimization. Through a detailed assessment of IT governance maturity, this study identifies key gaps and provides recommendations for improvement. Strengthening IT governance practices will enable PT PLN to enhance operational efficiency, mitigate IT-related risks, and align IT initiatives with corporate strategy. The study contributes to both academic research and practical applications by demonstrating the effectiveness of COBIT 2019 in IT governance evaluation.
