Abstract

Digital libraries play an important role in improving information accessibility and supporting digital literacy. However, many digital library applications still face usability challenges, particularly in navigation, collection retrieval, and digital reading experiences. In addition, previous studies have often focused on either interface design or usability evaluation separately, resulting in limited integration between user-centered design and usability assessment. This study aims to design and evaluate a digital library application by integrating Design Thinking and the System Usability Scale (SUS). The Design Thinking approach was implemented through five stages: empathize, define, ideate, prototype, and test, to identify user needs and develop a clickable prototype using Figma. Usability evaluation was conducted with ten respondents using the SUS instrument. The proposed prototype includes key features such as book search, category-based catalogs, digital reading, and an administrative dashboard. The evaluation produced a SUS score of 77.75, indicating a good level of usability and positive user perception. This study contributes by integrating Design Thinking and SUS within a unified development process to create a user-centered and quantitatively validated digital library prototype.

Abstract

This study develops a web-based home sales application to support In-House Mortgage (KPR In-House) financing at PT Nirwana Propertindo Sejahtera. The previous manual process led to administrative delays, limited transaction traceability, and a high risk of data loss. However, studies addressing an end-to-end digital KPR In-House system that integrates online applications, payment gateway–based installment payments, and standardized usability evaluation remain limited. The system was developed using the Waterfall model within the System Development Life Cycle (SDLC) and includes housing catalogs, installment simulation, online KPR applications, and integrated installment payments. Evaluation was conducted using Black Box Testing and the System Usability Scale (SUS). The results show that all system functions operate as expected and achieved a SUS score of 88.25, indicating high usability. The implementation improves transaction traceability, reduces the risk of document loss, and supports payment transparency. This study contributes an end-to-end digital KPR In-House process model, payment gateway integration, and empirical usability evidence.
