Abstract

Attendance is the process of recording and managing attendance data that is carried out daily during working hours at each company. Errors in recording employee attendance greatly affect employee earnings. So, the validity of the recording is needed. The attendance recording system manually is error-prone and its recapitulation takes a long time. To overcome this, it is necessary to develop an attendance system that can be done quickly and produce valid reports regarding the time of entry and exit. In this study, a presence application will be developed using QR Code scanning by applying the Extreme Programming (XP) method. The extreme programming (XP) method offers stages in a relatively short time. Based on black box testing, the generated QR Code presence application is in accordance with user needs with a functionality test value of 100%

Abstract

In the world of education knowing the personality type of students is very important. This is because a person's personality is influential in his learning activities and how he digests and captures the material presented by the teacher. For this reason, knowing the classification of students' personalities needs to be identified so that teachers or students themselves can optimize self-change in a better and positive direction. This study aims to develop a psychological classification system for student personality types using the C.45 decision tree algorithm. The personality type used as a class in the classification is based on psychology, including: Sanguine, Phlegmatic, Choleric and Melancholic. In this study, a web-based system was developed, so that it is easy to use for teachers and students to recognize the personality of these students. To determine the personality of students psychologically, students answer questions in the system, then the system will classify based on the answers from these students. The C.45 decision tree algorithm serves to find knowledge or patterns of characteristic similarity in a particular group or class. From the test results, the pecision value is 90%, the recall is 85% and the accuracy is 88%. This shows that the C.45 decision tree algorithm can perform personality type classification well

Abstract

D’Amore Café is a micro-scale culinary business that previously relied on manual financial recording methods, such as handwritten ledgers and spreadsheets (Rizal et al., 2021). This approach was prone to human error, reporting delays, and difficulties in real-time financial monitoring (Suryani & Suharsono, 2020). To address these issues, a web-based financial application was developed to automatically record, store, and display structured financial data in an accessible way for non-technical users. Built using PHP, JavaScript, MySQL, the system followed the Waterfall model, including planning, analysis, design, implementation, testing, and maintenance (Kumar & Bhatia, 2019). Features include inputting expenses, importing revenue data from Excel, generating reports, calculating balances, and printing outputs. Results showed improved operational efficiency by up to 60%, faster daily/weekly reporting, and more accurate access to financial data. User testing confirmed its intuitiveness and effectiveness for MSMEs without technical skills (Praditha & Wibowo, 2022). The system also enhances data security, accuracy, and transparency in financial management. For future development, mobile compatibility, cloud integration, and advanced analytics are recommended to support scalability (Wibowo et al., 2023). This digital solution enables better cash flow management and strategic planning for small business owners, helping them make informed decisions based on reliable financial insights.

Abstract

This research aims to design and evaluate an information system or technology-based application specifically developed to enhance efficiency and accuracy in data management. In today’s rapidly evolving digital landscape, organizations face increasing demands for reliable, high-performance systems capable of managing complex datasets with precision and speed. To meet these demands, this study focuses on the creation of a robust system that not only fulfills functional requirements but also ensures optimal performance, user-friendliness, and scalability for potential integration into various operational environments. The system was developed through a structured and systematic methodological approach, encompassing key stages in the software development lifecycle. These stages included comprehensive requirement analysis, conceptualization and design of the system architecture, implementation of modular components, and rigorous testing of both functionality and overall system performance. Each phase was carried out iteratively to ensure alignment with end-user expectations and to identify and mitigate potential issues early in the development cycle. This phased methodology contributed significantly to minimizing errors during deployment and ensured that the final product met all specified performance benchmarks. The data used in this study were collected through simulations and real-world usage scenarios to ensure high validity and reliability in practical implementation contexts. Simulated data allowed for.
