This study compares the scalability and maintainability of three prominent programming paradigms-functional programming (FP), object-oriented programming (OOP), and declarative programming (DP)-in the context of distributed data processing systems. The research aims to evaluate how each paradigm performs under increased data volume and its ability to handle complex operations, while also assessing the ease of maintenance through code readability, modularity, and the flexibility of updating and debugging. The study employs a comparative experimental design, implementing identical data processing tasks, such as data aggregation, filtering, and transformation, across each paradigm. Key findings indicate that FP and DP outperform OOP in terms of scalability, with their stateless nature and high-level abstractions enabling efficient parallel processing and task distribution. FP, with its emphasis on immutability and concurrency, and DP, with its focus on describing desired outcomes rather than implementation specifics, both demonstrate superior performance in handling large datasets. However, while OOP excels in modularity and flexibility, its reliance on mutable state and shared resources hampers its scalability in distributed environments. In terms of maintainability, both FP and DP offer clearer, more maintainable code due to their abstraction levels, making them easier to update and extend. OOP, while modular, presents challenges in managing mutable state, complicating maintenance. This paper concludes with practical recommendations for developers on when to use each paradigm based on system requirements and suggests areas for future research, such as hybrid paradigms and long-term maintainability studies in real-world applications.

The traditional homes of indigenous communities in Indonesia are highly vulnerable to natural disasters, particularly earthquakes, due to Indonesia's location in the Pacific Ring of Fire, which experiences high seismic activity. This situation demands the strengthening of traditional buildings to withstand potential earthquakes. Stilt houses, as a form of traditional architecture, possess characteristics that actually support earthquake resilience, such as flexible structures, the use of lightweight materials, and the application of local wisdom passed down through generations. With the development of modern construction techniques, stilt houses have the potential to become safer and more adaptable dwellings to earthquake shocks. However, indigenous communities, particularly those living in earthquake-prone areas and with lower levels of education, often face limited knowledge and skills related to the basic principles of earthquake-resistant construction. This lack of understanding results in traditional house construction without considering structural safety aspects, ultimately increasing the risk of serious damage and even collapse during an earthquake. These impacts not only threaten life but also cause significant material losses. This community service activity aims to improve the preparedness and resilience of the Sentani Indigenous community by developing earthquake-resistant stilt house models, increasing knowledge and skills in earthquake-safe house construction and maintenance, and encouraging the use of innovative technology and materials. The expected outcomes are the creation of model houses that can serve as examples and the dissemination of information on earthquake-resistant construction technology.
