Abstract

The development of the photography industry today is not only determined by the quality of the final photos but also by the convenience and ease of service received by customers. CloudPhoto Studio Ciamis still relies on manual methods to serve its customers, such as through WhatsApp and Instagram, which often lead to problems such as delayed confirmations, poorly organized data, and inconsistent services. This condition highlights the need for a more structured and interactive web-based information system to improve service quality. This research applies the concept of Customer Relationship Management (CRM) in the development of a web-based information system designed to enable customers to make reservations, access package and price information, view portfolios, and experience faster, more efficient, and personalized services. The prototype method was used in this study, emphasizing user involvement at every stage. The process begins with communication to gather requirements, quick plan to outline a simple strategy, quick design to produce the initial interface, construction of prototype to develop the system prototype, and delivery & feedback to refine the system based on user input. The results show that the implementation of this web-based CRM system can improve service efficiency, strengthen the professional image of CloudPhoto Studio, and maintain customer loyalty through more personalized services. Furthermore, the system also creates opportunities for the studio to expand its market reach more effectively. Thus, the development of a CRM-based information system can be considered a crucial strategy to support the sustainability and competitiveness of the photography industry.

Abstract

PT. Global Nikel Multiguna still applies a manual system in leave management. This process causes delays, risks of recording errors, data manipulation, and document accumulation. This study was conducted to design a more effective and efficient web-based leave information system using the Rational Unified Process (RUP) method with four main phases: inception, elaboration, construction, and transition. Research data were collected through observation and interviews with the company, then analyzed to formulate system requirements. System modeling was carried out using the Unified Modeling Language (UML) method, followed by interface design in the form of wireframes, and an initial implementation using the Laravel framework. To ensure the functionality works as intended, functional testing was conducted using the black box method. The results show that the designed system can perform basic functions, namely leave submission, leave approval, employee data management, and report generation according to the company’s needs. However, this study is still limited to the design and initial testing stages, thus it does not yet include deployment and direct user evaluation, and further development is required so that the system can be fully implemented in the company.

Abstract

This study aims to address inventory management problems at Rizki Wholesale Store, which still relies on manual record-keeping. The lack of an accurate prediction system often leads to overstocking of certain items or stock shortages for products that are in high demand by consumers. By applying data mining techniques using the K-Nearest Neighbor (KNN) method, this study processes historical transaction data from January to December 2024 to classify 50 types of products into the categories of “Best-Selling” and “Non-Best-Selling.” The analysis results indicate that the KNN algorithm is capable of providing accurate classification based on the proximity distance between sales data points. These findings offer strategic guidance for the store owner in managing inventory procurement, particularly for essential products such as food items and cleaning supplies, which consistently demonstrate high sales performance.

Abstract

Water scarcity and mismanagement represent critical global challenges exacerbated by climate change and rapid urbanization. In response, Artificial Intelligence (AI) and Machine Learning (ML) have emerged as pivotal technologies optimizing equitable water distribution, real-time monitoring, and sustainable conservation strategies. This study conducts a Systematic Literature Review (SLR) based on the PRISMA guidelines to synthesize the current landscape of computational AI applications targeting water conservation. From an initial identification of 1,449 records gathered from the Scopus database, stringent inclusion criteria filtered specifically for English publications within the Computer Science structural domain spanning the years 2015-2025. This uncompromising filtration yielded exactly 19 empirical, high-impact peer-reviewed articles for qualitative synthesis. A robust thematic analysis reveals three primary domains mapping this niche research architecture: (1) Precision Agriculture and Smart Irrigation Systems leveraging IoT, (2) Predictive Modeling and Real-time Grid Monitoring for urban leakages, and (3) Water Quality and Biodiversity Modeling. Finally, this review highlights critical future research directions, including the demand for explainable AI (XAI) models in hydrology, resolving data privacy and sparse data scenarios using federated learning, and integrating extreme-event climate indices into dynamic resource planning algorithms.
