In the contemporary digital era, the increasing incidence of fraud and unwanted communications has become a serious concern, driving the adoption of security apps like GetContact. This study aims to analyze public perception of the GetContact app by conducting a systematic sentiment analysis of user reviews on the Google Play Store. Using a text mining framework, 990 user reviews were collected, processed to ensure data quality, and then classified using the Naive Bayes algorithm to determine sentiment polarity. Quantitative results show a significant dominance of negative sentiment, comprising 419 reviews (42.3%), followed by positive sentiment, comprising 291 reviews (29.4%), and neutral sentiment, comprising 280 reviews (28.3%). Qualitative analysis through data visualization reveals that the primary user complaints center on basic functionality issues such as login difficulties, while positive sentiment is driven by the perception that the app is very helpful. These findings provide critical actionable insights for developers to prioritize improvements in areas of greatest user concern. This study advances sentiment analysis by demonstrating the efficacy of Naive Bayes in classifying unstructured app reviews, offering a scalable approach to evaluating user feedback in mobile app development.

IT Governance (ITG) ensures an organization's technological capabilities align with its business strategy. Although frameworks like COBIT 2019 offer structured guidelines, many assessment techniques rely on qualitative measures, which can compromise objectivity. This paper proposes a novel quantitative approach that integrates Factor Analysis (FA) and Structural Equation Modeling (SEM) to measure IT Governance maturity. By mapping each COBIT 2019 domain—EDM, APO, BAI, DSS, and MEA—onto a latent construct, organizations gain empirical insights into their governance status. Exploratory and confirmatory factor analyses validate these domains, while SEM reveals the magnitude and significance of each domain's impact on overall IT Governance maturity. A real-world example from a financial services company, "FinServEU," demonstrates how this framework can prioritize improvements, enhance regulatory compliance, and promote continuous monitoring. The results highlight that quantitative ITG modeling provides a reliable basis for informed decision-making and optimal resource allocation, bridging the gap between broad qualitative assessments and actionable strategies. This approach is crucial for the field of informatics and computer science, as it offers a robust, reproducible, and objective framework for evaluating a key aspect of digital transformation, ensuring that technological progress is guided by sound, data-driven principles.

Learning media is currently widely used in the teaching and learning process. Technology and information are two things that cannot be separated from one another in the ever-evolving digital era. Likewise with the education sector which underwent a significant transformation. The Learning Management System is a software application for online learning that supports delivering material online, discussing with students, and controlling student performance. This technological advancement has made many tertiary institutions use web application-based information technology. The current problem is the lack of complete features and less interactive functions to support the Learning Management System. In addition, when the user wants to be more interactive in learning, the Learning Management System generally has a separate feature, which requires the user to switch platforms to use the feature. The development of this Learning Management System is expected to become a more interactive learning platform and have complete features compared to other systems. System analysis is done by describing a system as a whole into its component parts. This is intended to identify and evaluate problems that will later find weaknesses and strengths in the system. The method used in this study is the waterfall starting from making the design of the system to implementing the system that runs in a production environment. The results of this study have several features needed for in-person and online learning which generally do not exist in other Learning Management Systems such as video conferencing, docs & files, group chats, automatic check-ins.

High electricity bills are often caused by a lack of monitoring the use of electronic equipment in the household. One common problem is forgetting to turn off appliances that are not in use, which causes electricity to continue flowing and increases electricity bills. Currently, although there are several technologies that allow the control of appliances, their features are still limited, especially in lamps. This research focuses on developing Internet of Things (IoT) technology in the field of energy and control. One of the implementations is using a Raspberry Pi microcontroller to monitor the use of electrical energy in households. In order to make the use of IoT components more efficient and easier, a NODE-RED-based system is used which serves as a link between end users and IoT equipment. For monitoring IoT components, a web dashboard using the Laravel framework was also built. This allows users to view the components used and the activities that occur on their IoT equipment.

One of the benefits of implementing enterprise architecture is creating harmony in between business and information technology for the needs of organization, beside that information system architecture is also a management practice and technology that is useful to improve company performance by allowing them to see themselves in terms of a holistic and integrated view of strategic direction, business practices, information flows and technological resources (Wiranti et al., 2020). The application of enterprise architecture is inseparable from how to plan an organization but also in designing enterprise architecture. In carrying out the design required a complete and easy methodology. TOGAF (The Open Group Architecture Framework) as a framework for building generic enterprise architectures provides complete and easy-to-understand and implement stages. Currently there are not many applications or systems that provides local city information, communication and social media (events, tourist sites, business listings, communities, so on and so forth). Although there is, the application or system does not provide information in an informative manner, the information is scattered in various sources. KotaKita is a product which will be build by startup organization to fill the gap and providing the information on the locality of areas throughout Indonesia, KotaKita can be used as a means of communication of local regional social communities. The Implementation of enterprise architecture (EA) in startup organizations is not a must, but the implementation of enterprise architecture will be very useful in building an architectural blueprint that can be used to make better plans and decisions.
