In the current digital era, managing sales transactions manually is inefficient and prone to recording errors. This research aims to develop a web-based Point of Sale (POS) application for the Phi Phi Thai business using the Extreme Programming (XP) software development methodology. XP was chosen for its support of rapid iteration, adaptability to changing user requirements, and strong collaboration between developers and stakeholders. The developed application includes key features such as user registration and login, product ordering, menu and customer management, expense tracking, and financial and sales reporting. Testing was conducted using the Black Box Testing method to ensure that all functionalities performed according to specifications. The implementation results indicate that the application improves operational efficiency, reduces transaction errors, and provides real-time information for business owners to support better decision-making. Furthermore, the application of Extreme Programming (XP) methodology in the development process allows time for regular evaluation and refinement of the application based on feedback from end users. Each iteration produces a version of the software that can be immediately tested and used, minimizing the risk of system failure during final implementation. This approach also encourages lightweight yet relevant documentation and open communication between the technical team and business owners. Thus, the developed Point of Sale application not only meets current functional requirements but also has a high degree of flexibility for further development as Phi Phi Thai's business grows in the future.

Technology that develops very rapidly brings many changes, especially in the development of medical records in hospitals that are increasing. Electronic medical records bring many benefits, one of which is improving the quality of services in hospitals. The medical records used at Hermina Arcamanik Hospital are mostly electronic-based, including reporting. However, problems were found in the medical record installation, namely, there were several reports that had not been managed optimally. This is because reporting still uses google spreadsheets which requires data to be moved manually one by one, so it takes a long time, and the quality of reporting becomes less accurate. A real example of this problem can be seen in the process of reporting patient Mortalitys. Meanwhile, accurate and systematic reporting of Mortality data is essential in supporting decision-making in hospitals. Therefore, the design of a patient Mortality reporting information system is urgently needed to make time efficient and improve the quality of reports. The method used in designing this system is extreme programming and web-based. The results of this information system design are able to shorten the time to make Mortality reports and can produce accurate data

This literature review discusses the application of Agile methodology in modern software development. Agile offers a flexible, iterative approach that contrasts with traditional waterfall models. The objective of this study is to provide insights into how Agile frameworks such as Scrum, Kanban, and Extreme Programming have influenced development speed, software quality, and team collaboration. Methodologically, the study synthesizes findings from recent academic and industrial literature from the last five years. The results show that Agile enhances adaptability and customer satisfaction, although challenges remain in large-scale implementations.  

Construction management is vital for coordinating and overseeing projects to ensure alignment with planned objectives. Factors such as time, cost, and quality demand strict control, as discrepancies between initial plans and actual execution can cause significant challenges. In ship construction, delays in material execution and delivery are frequent bottlenecks, leading to schedule disruptions and negatively affecting project outcomes. Addressing these issues requires effective management and robust risk mitigation strategies. This study proposes a web-based ship construction project monitoring system using the Laravel framework and MySQL database. The system is developed using Extreme Programming (XP), an agile methodology that emphasizes iterative improvement, stakeholder collaboration, and adaptability. XP practices, including test-driven development, pair programming, and continuous integration, ensure the system is reliable, adaptive, and responsive to evolving user needs. Frequent stakeholder feedback and incremental development cycles enable the system to tackle dynamic challenges, optimize resource utilization, and ensure timely project delivery. By incorporating XP principles, this study demonstrates the potential of agile methodologies to enhance construction project management. The resulting system provides a flexible and efficient solution for mitigating delays and improving the overall success of ship construction projects.

Information system is an important component of any institution, a proper information system could bring a lot of benefits. An example of this is the attendance system. Chinchin Production faced a difficult challenge of managing human resources because previously employees had to sign their attendance manually, which is proven to be inefficient. The solution to this challenge is a proper attendance system to replace the old manual attendance system. The development methodology used is Extreme Programming (XP). Extreme Programming (XP) is an Agile project management methodology that aims for speed and simplicity. The prototype is designed using Unified Modeling Language (UML) as a modelling tool to visualize the structure of the system, as well as Figma to design the User Interface (UI) of the system. This attendance system helps Chinchin Production in managing human resources.

The Bengkalis Regency Education Office (Disdik) provides Local Children's Scholarships to students in an effort to help students to alleviate the dependents of the Single Tuition Fee (UKT) in pursuing education. In determining the recipient of the Tempatan Children's Scholarship, the Education Office government carries out several stages manually such as collecting all the files of students who register, after which the Education Office checks the completeness of the student files one by one, gives a value for each predetermined criterion and manually calculates the value of the criteria. A decision support system for recipients of web-based Local Children's Scholarships is needed to help determine recipients of Local Children's Scholarships to be faster and more accurate. This system is made using the Simple Additive Weighting (SAW) method and Multi Attributive Border Approximation Area Comparison (MABAC) to facilitate the calculation and comparison of the value of each alternative in the system, by determining the ranking based on the largest value as the best alternative. The result of the application of the SAW and MABAC methods in the system is that the system displays alternative data sequentially based on rankings that can help in determining the recipient of the Local Children Scholarship. From 60 field data, the application of SAW and MABAC methods on this system has an accuracy of 83.3%. The development method used is the Extreme Programming method.

With the changing times, technology has become more sophisticated and powerful. Even all circles of society also feel the impact, as time goes by many people have taken advantage of this technology, thus making it easier for users to carry out activities in each of their activities. Especially in this millennial era, which predominantly uses everything digital. For example, new students who study to the next level at a dominant university from outside the region who need a temporary residence or what is commonly called a boarding house. The difficulty encountered at first was the difficulty of getting information and locations that were easily accessible by students to campus. In this way researchers take advantage of existing problems by utilizing technology to create an information system. With this application, it is hoped that it will make it easier for students to find boarding houses that match the student's wishes and assist the owner of the boarding house in promoting his boarding house. By making this boarding house application, it is a form of utilizing existing technology so that it can be used anywhere and anytime. By using this extreme programming method, it is software development that gives users access rights to add or change application processes. So a website was created to build applications for boarding houses in the city of Sukabumi.
