Yahya Nur Ifriza, & Widhiya Ninsiana Introduction The decline in interest in learning Javanese can be attributed to several factors.
First, the influence of globalization and modernization has shifted peopleAos attention away from regional languages, including Javanese, creating challenges for both teachers and students in integrating culturally rooted materials into modern learning contexts (Daniar et al.
, 2.
The widespread use of Indonesian and foreign languages across media and formal education further diminishes the perceived relevance and necessity of learning Javanese.
Second, the limited availability of innovative educational resources and supportive curricula also contributes to this decline (Bilqis et , 2.
When school curricula do not emphasize the importance of understanding and preserving Javanese, learnersAo motivation to study the language tends to weaken.
Moreover, lifestyle changes influenced by increasingly urban and modern environments play a role in reducing interest in Javanese (Elika & Nurhayati, 2.
Individuals heavily exposed to international pop culture may feel that understanding or using Javanese is no longer essential in their daily lives.
Therefore, efforts to revitalize interest in learning Javanese must employ creative and contextually relevant approaches that resonate with contemporary experiences (Tahyudin & Sholihati, 2.
The development approach used in this research integrates the System Development Life Cycle (SDLC) and User-Centered Design (UCD).
SDLC is a structured system development framework that outlines the main stages of development, typically consisting of five key activities:
analysis, design, implementation, testing, and maintenance (Widharma, 2.
Meanwhile.
UCD is an approach that prioritizes user involvement, both current and potential users, throughout the processes of data collection, design evaluation, and testing (Hartawan, 2.
Together, these approaches support the development of digital Javanese literacy initiatives aimed at addressing the ongoing decline in Javanese language use in todayAos digital era.
The use of Javanese as part of cultural heritage and tradition has decreased due to the increasing dominance of Indonesian and foreign languages in digital spaces.
The development of Novaja.
id through the SDLC framework is expected to ensure that the application offers reliable and stable functionality while remaining adaptable to evolving technological demands.
SDLC
provides a systematic structure for planning, developing, testing, and maintaining applications, which is essential for ensuring the long-term sustainability and effectiveness of Novaja.
id (NakiN et , 2.
In parallel, the application of User-Centered Design emphasizes the importance of understanding user needs, preferences, and experiences at every stage of development.
By centering the design process on users.
Novaja.
id is expected to become more intuitive, accessible, and aligned with the expectations of Javanese-speaking users, ultimately increasing their interest in reading Javanese novels (Christanto & Singgalen, 2.
The proposed problem-solving approach for developing the Novaja.
id Javanese Novel Library application consists of a series of planned and structured steps.
First, the use of the System Development Life Cycle (SDLC) enables the research to proceed systematically from the planning stage through to maintenance, ensuring that each phase of Novaja.
idAos development is clearly organized and well executed.
These phases include user needs analysis, system design, implementation, testing, and maintenance, with a strong focus on application reliability and Furthermore, the User-Centered Design (UCD) method is applied to prioritize an optimal user experience.
This involves identifying potential user characteristics, collecting feedback from users throughout the development process, and tailoring the user interface to their preferences and needs.
By actively involving users at every stage of the development cycle.
Novaja.
id is designed not only to offer adequate technical features but also to remain easily accessible and usable for Javanese-speaking users (Laato et al.
, 2.
This integrated approach aims to create an application that is not only technically robust but also relevant and user-friendly.
By combining SDLC and UCD, this solution is expected to make a positive contribution to Javanese language Diglosia: Jurnal Kajian Bahasa.

id application as a form of Javanese cultural preservation literacy and reading interest, address the challenges of the digital era, and support the preservation of local culture.
The development of regional language literacy-based applications continue to evolve alongside advancements in technology.
Although several applications have been created to enhance regional language literacy, many still face limitations, particularly in integrating comprehensive development methods such as the System Development Life Cycle (SDLC) and User-Centered Design (UCD) (Sylvain & Chaniaud, 2.
Some platforms also lack attention to the long-term sustainability of regional language use in the digital era.
In response.
Novaja.
id, the Javanese Novel Library, offers a more integrated solution by combining a robust development methodology with a user-centered approach (Lidya Maukar et al.
, 2.
The uniqueness of this research lies in its comprehensive approach to developing a Javanese literacy application by adopting the SDLC framework to ensure a stable and well-tested system and implementing User-Centered Design to create a user-friendly interface (Kim et al.
, 2.
Its strong focus is on the sustainability of regional languages and literacy positions Novaja.
id as an innovative contribution to cultural preservation and the enhancement of reading interest within the Javanese-speaking community, while also serving as a model for the development of similar solutions in other regional cultural and linguistic contexts.
The roadmap for the development of the Novaja.
id Javanese Novel Library application from 2022 to 2026 begins with planning and needs analysis.
In 2023, the system and user interface are designed using the User-Centered Design approach.
The year 2024 focuses on implementation and testing, followed by maintenance activities in 2025.
Finally, in 2026, the applicationAos impact on literacy and reading interest within the Javanese community will be evaluated.
This roadmap reflects a strong commitment to supporting literacy development and preserving Javanese culture .

Novaja.
id has been designed by carefully considering the needs and preferences of these primary users.
The main aspects implemented include: first, clear navigation: ensuring that users can easily find the information or features they need without confusion.
Second, contrasting colors: using color combinations that make interface elements easy to see and distinguish, thereby increasing readability and visual comfort.
Third, easy-to-read typography: selecting appropriate font types and sizes to ensure that text can be read comfortably by users.
Forth, user personas:
focusing on students with relatively high digital literacy ensures that the interface supports their technological capabilities while remaining intuitive, efficient, and accessible.
A low-fidelity interface is an early representation or simple prototype of a user interface (UI) design created with minimal detail, which does not yet depict the final product, similar to a sketch.
Its main purpose is to test basic ideas and concepts before investing significant time and resources in developing a more detailed and refined design.
Low-fidelity interfaces typically use rough blackand-white lines, basic geometric shapes, and placeholder text.
They do not include details such as colors, images, or complex typography.
Instead, these prototypes emphasize the arrangement of elements, navigation, and user flow rather than visual appearance and aesthetics.

id application has proven effective.
SDLC ensures a systematic development process, from planning to maintenance, while UCD ensures that user needs, and preferences are at the center of every stage of development.
Advantages success in development: The application was successfully developed according to plan, with the features desired by users.
This shows that the implementation of SDLC has succeeded in maintaining the timeline and quality of the product.
Focus on users: The implementation of UCD makes the application more user- friendly, as evidenced by the results of usability testing.
Users find the application interface intuitive and easy to use.
The disadvantages are time and resources:
The iterative UCD process requires more time and resources, which can be a challenge if there are budget or time constraints.
Adaptation to feedback: The application needs to be continuously developed to adapt to changing user needs.
Therefore, improvements and additions to features must be made periodically.
