%X This study discusses the implementation of Software Quality Assurance (SQA) on the Swagger Petstore dummy API using the Agile methodology, specifically through the Grafana K6 tool, standardized by ISO/IEC 25010. The research is motivated by the lack of attention to the role of SQA in software development, especially within startups that prioritize efficiency. The objective is to integrate SQA into Agile through iterative sprints and apply performance-based testing metrics aligned with established software quality standards. The methodology involves a simulated project using the Scrum framework, where each sprint tests one of the three main API endpoints (user, store, and pet) across five ISO/IEC 25010 software quality characteristics: performance efficiency, compatibility, usability, maintainability, and reliability. Grafana K6 was chosen as the testing tool for its lightweight execution, JavaScript-based scripting, and comprehensive reporting features. The results of this study show that Software Quality Assurance (SQA) can be effectively integrated into each stage of Agile development, with the test results serving as a reference for evaluating API quality. This aligns with the use of Grafana K6, standardized by ISO/IEC 25010, and builds upon previous related research. These three components (Agile methodology, K6, and ISO/IEC 25010) have proven to support the SQA process in a practical and efficient manner within an Agile project context. This research is expected to serve as a reference for implementing Agile-based SQA using international standards in API testing. %I Fakultas Teknik Universitas Sultan Ageng Tirtayasa %A Dhimas Tyas Granadi %D 2025 %L eprintuntirta53330 %T SOFTWARE QUALITY ASSURANCE PADA API SWAGGER PETSTORE DENGAN PENDEKATAN METODE AGILE MENGGUNAKAN TOOLS GRAFANA K6 YANG DISTANDARDISASI ISO/IEC 25010 %K Agile, Grafana K6, ISO/IEC 25010, Software Quality Assurance, Swagger Petstore
