Abstract

This study presents an overview of the research aimed at optimizing library information retrieval through the utilization of the Vector Space Model (VSM) method in a computer science context. Libraries, as publicly financed collections, provide extensive knowledge resources, eliminating the need for individual book purchases. However, the challenge lies in efficiently navigating the expanding library collections. To tackle this issue, the study employs information retrieval techniques, particularly the VSM method, which assesses term similarity by assigning weights to terms, enabling document and query representation as vectors. The relevance between documents and queries is measured through vector similarity. This approach, integrated with indexing, streamlines collection retrieval in libraries. Employing the Waterfall model for system development, the research outlines phases like analysis, design, coding, testing, and implementation. While effective, the model's rigidity in accommodating evolving requirements poses limitations. The VSM method's numerical representation of text documents facilitates precise similarity calculations, supported by TF-IDF values indicating term importance in documents relative to the corpus. The study further extends to system design using UML diagrams and a visitor interface, integrating VSM for efficient search functionality. Black-box testing confirms the robustness of the system components and interfaces. Overall, this research presents a systematic approach to enhance information retrieval in libraries, emphasizing the VSM's pivotal role in optimizing document searches within expansive collections.

Abstract

Bhayangkara Palembang Hospital is a hospital classified as a Level III Bhayangkara Hospital, which is at least capable of providing health services in the form of eleven basic specialists in providing non-medical logistical needs. The system used by Bhayangkara Palembang Hospital is still very limited, starting from submitting non-medical logistics needs from each section, approval of the procurement of non-medical logistics needs by the leadership, and managing non-medical logistics data by the admin section. With the non-medical logistics procurement system that is currently running, Bhayangkara Palembang Hospital requires more time because the request to procurement process has to go through a fairly long process. This will affect the quality of service at Bhayangkara Hospital in Palembang because non-medical logistics supplies cannot be fulfilled quickly before old supplies run out. Therefore, to improve the quality of service at Bhayangkara Palembang Hospital, especially in the procurement of non-medical logistics, changes are needed to the current system by implementing the non-medical logistics information system at Bhayangkara Palembang Hospital so that it can simplify and speed up the process of submission, approval, data management, and procurement of non-medical logistics.

Abstract

In this study, the challenges faced by Tanjung Kerang Village in providing optimal community administration services using conventional methods are highlighted. The village, despite having a relatively large population, faces issues such as long queues, delays due to forgotten requirements, and difficulties in accessing data for administrative processes. To address these challenges, the study proposes the implementation of a community service administration information system using the Prototype Model in software development. The Prototype Model, characterized by quick iterations, user involvement, and continuous refinement, is chosen as the methodology for system development. This approach allows for the creation of a preliminary version of the software that undergoes testing and refinement in multiple cycles. The iterative nature of the model, coupled with user feedback, facilitates the gradual convergence towards a final, fully functional system. In conclusion, the Prototype Model proves instrumental in addressing the identified challenges, offering a systematic and iterative approach to enhance community administration services. The proposed information system has the potential to significantly improve service delivery, making it more effective and efficient for both administrators and the community.
