Abstract

Data and information are essential in various fields today, as well as in the field of education, especially in universities. Some universities already have information systems that support data and information needs. However, the system has not been integrated, so it cannot provide data and information needs quickly and in an integrated manner. Information systems in universities are still primarily departmental because each was built at a different time and uses another platform. The departmental nature of this information system causes inaccuracies and inconsistencies of data that drive the information produced in reports and data reused in transactions to be invalid. Invalid data, in the end, also impacts decision-making taken by management. This study aims to develop a data warehouse at a university to integrate academic data using a star schema. The method used is the Nine Step Methodology. The result of this research is data warehouse architecture used in the academic field; fact tables and ERDs have been designed at the current stage of designing a Prototype of the Study Program Performance Sheet (LKPS).

Abstract

PT Rapier Technology International applies scrum in developing the BBLobster Content Management System (CMS). Scrum is a framework for developing an iterative, flexible, and effective BBLobster CMS designed to deliver significant value quickly. This study aims to identify the problems encountered in scrum implementation and validate the factors that influence the interaction with Scrum adoption during the BBLobster CMS development process using variable measurements. The measurement variables are the team factor variable, individual factor variable, technology factor variable, organizational factor variable, and scrum adoption variable. They analyzed the measurement of the data model (outer model) and structural model (inner model) using SmartPLS 3.0 after data collection using a questionnaire via google forms. The results of this study show that the analysis of the structural model test conducted by knowing the value of R-Square (R2) is a team factor variable, individual factor, technological factor, and organizational factor that has an influence of 67.4% on scrum adoption.

Abstract

The current era is marked by rapid technological advancements, with e-commerce being one of the most prominent innovations that caters to people's needs and saves time. In this study, we examine the factors that significantly influence user satisfaction in Shopee, a popular e-commerce platform, using the End User Computing Satisfaction (EUCS) method. Data was collected through the distribution of questionnaires to students in the DKI Jakarta area. Our analysis revealed that Content, Accuracy, Format, Ease of Use, Timeliness, and Fulfillment are all significant factors that affect user satisfaction. Together, these factors explain 78.7% of user satisfaction. Additionally, through T-tests, we found that only three variables have a significant and positive impact on user satisfaction: Ease of Use, Timeliness, and Fulfillment. These findings indicate that e-commerce platforms should prioritize these factors to enhance user satisfaction.
