Abstract

The development of information technology requires the industry to transform into a digital system to improve efficiency and service. CV. Tjahaya Logam, as a nail manufacturing company, still uses a manual ordering system that has the potential to cause recording errors and late confirmation. To overcome these problems, the NailFlow application interface was designed using the Design Thinking method with five main stages: Empathize, Define, Ideate, Prototype, and Test. The purpose of this design is to produce a user interface (UI) and user experience (UX) design that is intuitive, efficient, and meets the needs of customers and company admins. The design results in a prototype application with key features such as digital ordering, real-time order tracking, and stock management. Testing using the Black Box Testing method shows that all interface elements function as expected. With this interface design, it is hoped that NailFlow can improve the efficiency of the ordering process, reduce errors, and provide a better service experience for CV. Tjahaya Logam customers.

Abstract

This study evaluates the performance and quality of an external alarm system using the ISO/IEC 25010 software product quality model. The evaluation focuses on eight quality characteristics, namely functional suitability, performance efficiency, compatibility, usability, reliability, security, maintainability, and portability, to provide a comprehensive assessment of the system. A quantitative approach was employed, and data were analyzed using a measurement model to test construct validity and reliability. The results of the validation test show that all indicators have outer loading values above 0.70 and Average Variance Extracted (AVE) values exceeding 0.50, confirming satisfactory convergent validity. Reliability testing also indicates strong internal consistency, with Cronbach’s Alpha and Composite Reliability values for all constructs exceeding the recommended threshold of 0.70. These findings demonstrate that the proposed measurement model is valid and reliable for evaluating external alarm systems. Overall, the study confirms that ISO/IEC 25010 provides a robust and effective framework for assessing software quality and performance in safety-critical alarm systems.

Abstract

This study assesses the performance and quality of an external alarm system using the ISO/IEC 25010 framework. The evaluation covers eight quality characteristics: functional suitability, performance efficiency, compatibility, usability, reliability, security, maintainability, and portability. Data were collected through structured questionnaires and analyzed using Partial Least Squares–Structural Equation Modeling (PLS-SEM). The measurement model results indicate that all constructs meet the required validity and reliability criteria. Outer loadings range from 0.730 to 0.956, exceeding the recommended threshold of 0.70. The Average Variance Extracted (AVE) values are above 0.50, confirming convergent validity. Furthermore, Cronbach’s Alpha and Composite Reliability values exceed 0.70 for all constructs, demonstrating strong internal consistency. These findings confirm that the external alarm system meets established software quality standards and performs reliably across multiple dimensions. The validated model provides a robust foundation for further structural analysis and quality improvement strategies.
