https://ejournals.umn.ac.id/index.php/SI/article/view/3410
<p>Investment in Indonesia during the COVID-19 pandemic increased. One of the significant and good indices in describing the condition of stocks in Indonesia is LQ45. Dlaam LQ45 The largest market capitalists are held by the financial sector Specifically the bank subsector therefore it needs to be further researched regarding these stocks. One of the interesting things is whether these stocks deserve to be considered a good investment instrument. One of the efforts to assess investment instruments is through the valuation stage. The valuation method used there are two, namely relative valuation with price to book value benchmarks and price earnings ratio and absolute valuation with dividend growth model method and some modifications of the model. From the results obtained, the recommendation of the position of the four financial stocks in LQ45 varies depending on the valuation technique used. On this basis, it can be said that it is important to know, know, and ethically the valuation techniques used are appropriate, good, and correct.</p>Ferry Vincenttius Ferdinand, Edison Hulu, Gracia Shinta S.

https://ejournals.umn.ac.id/index.php/SI/article/view/3473
<p class="Abstract"><span lang="EN-GB">IT governance is the responsibility of the board of directors and executive management of a company that ensures the company information technology supports and expands the company strategy and objectives. But IT governance that does not support departments can have a negative or detrimental impact on the department. For this reason, it is necessary to take measurements to see the level of IT governance that is currently being implemented. The Facility Management Department is a department of PT Permata Graha Nusantara which is engaged in building management services that wants to see whether the ongoing IT system provides support to operational activities and provides better services to customers. To measure the capability of IT governance, the COBIT 5.0 framework is used as a reference in this study. Domain selection is done according to COBIT 5.0 standard and on the selection of the department 5 domains are tested, namely APO05 Manage Portfolios, APO10 Manage Suppliers, APO11 Manage Quality, BAI04 Manage Availability and Capacity, and DSS03 Manage Problems. Each domain chosen to have different aims and objectives and measured using standards set by the COBIT 5.0 framework. The measurement results are Capability Level which has levels from level 0 to 5. The target expected by the Facility Management department is level 4, but the results obtained are not in line with expectations and get level 3 in each domain tested, so this department must make improvements based on recommendations made based on the COBIT 5.0 framework.</span></p>Alexander Alvin Chui, Wella Wella

https://ejournals.umn.ac.id/index.php/SI/article/view/3475
<p>Information technology (IT) management is a process that a corporation or organization must carry out, particularly in terms of data management. The research employs a case study of a pipe manufacturer that has implemented a human resources system to manage employee information. To avoid problems in the data management process that can impede company performance, the company must have good information technology governance capabilities in the data management process. This research will focus on measuring and evaluating the capability of information technology governance at the company, as well as making recommendations to improve the company's existing IT governance. The COBIT 2019 framework will be used to assess the company's IT governance capabilities using qualitative data collected from collaborative interviews with the company and supported by previous research literature. The measurement focus will be on IT infrastructure for data management and operations management to support the data management process. APO01 - Managed I&T Management Framework, APO14 - Managed Data, and DSS01 - Managed Operations are the COBIT 2019 processes to be monitored. The study's findings include the realization of IT governance capabilities in the APO01 domain and a lack of IT governance capabilities in the other two domains, namely APO14 and DSS01. The capability level is stopped at level 2 for the APO14 and DSS01 domains, which is one level below the declared aim of level 3. The recommendations will center on enhancing the IT governance skills of the two domains that fail to meet the company's capability targets.</p>Jason Nathanael Holman, Ririn Ikana Desanti

https://ejournals.umn.ac.id/index.php/SI/article/view/3483
<p><em>Abstract</em>—Stakeholders are parties affected by a project, with both positive and negative impacts. In a project, the expectations of these stakeholders must be managed properly, and a project manager plays an important role in satisfying and balancing the interests that exist between them. The stakeholder analysis process needs to be carried out in detail. It must also be supported by the right tools so that it can reveal new insights that may have been hidden behind the stakeholder data. In this research, two techniques are proposed to increase the acuity of two tools that are often used in the stakeholder analysis process, namely the salience diagram and the power grid diagram. Improvements were made by using vectorization techniques for salience diagrams and applying Gartner's magic quadrant method to power grid diagrams. Both improvements can show more clearly the position of stakeholders in the categorization formed according to the two tools. Of course, this will further assist the project team in determining the right strategy for each stakeholder so that all elements support the project’s success.</p>Cornelius Mellino Sarungu

https://ejournals.umn.ac.id/index.php/SI/article/view/3566
<p>This study aims to evaluate the usability of a mobile-based application used to facilitate passengers in purchasing train tickets, the Access by KAI application. As an application widely used by the public, the usability evaluation is essential. The evaluation was conducted by measuring usability in three aspects: effectiveness, efficiency, and user satisfaction. The measurement involved 10 respondents who actively use the application. They performed the experiment at the usability laboratory. The level of effectiveness and efficiency was measured using task analysis, analyzing the final results of each respondent after performing five predetermined tasks. The results show that the effectiveness and efficiency of the application are good. However, the measurement of user satisfaction aspect using the SUS (System Usability Scale) method indicates less favorable results. This obviously results in poor user experience (UX) for users. Therefore, the practical implication of this study is the need for improvements to the application, both in the user interface (UI) and existing business processes, to enhance the user experience.</p>Lisana Lisana, Dea Almira Bena, Jessica Levina Sutanto, Evan Novandyanta, Kevin Kevin

https://ejournals.umn.ac.id/index.php/SI/article/view/3590
<p>The adoption of Population Information System is crucial to enhance work effectiveness and serves as a manifestation of transparency in population data management. The complexity from design to implementation of such a population information system poses its own challenges. There are at least three main issues in system design, namely time estimation, team management, and ensuring the quality of system being developed. These issues must be addressed early on to prevent potential team management problems during the design and development stages of the application. One suitable method that can be employed for the design of the population information system is the Scrum methodology. Scrum is a software development framework that emphasizes a collaborative and adaptive approach. It falls under the Agile methodology, aiming to produce products that are more responsive to changes and enabling teams to adapt quickly in a dynamic environment. Scrum also promotes transparency in the development process, aiding in monitoring system progress and information accuracy. Compared to the commonly used Waterfall method, the Scrum approach offers greater flexibility in dealing with changes in requirements or needs that may arise during the development process. While the Waterfall method tends to follow predefined in linear steps. The novelty of this research lies in the proactive approach to addressing the complexity of designing population information systems by implementing Agile methodologies such as Scrum. Thus, it is expected that the implementation of Scrum will bring significant changes in improving the effectiveness and transparency in the development of population information systems.</p>Putry Wahyu Setyaningsih, Arita Witanti, Krisna Widatama
