Abstract

Marketplace is one of the fastest growing digital innovations in the current technological era, which offers increased effectiveness and efficiency in product and service transactions. In the children's equipment and toy rental sector, it has the potential to help connect service providers and renters practically. However, the current rental process still faces several challenges, including manual procedures, lack of complete information, and low transaction efficiency, all of which hinder the rental experience and reduce user satisfaction. Therefore, it is important to design the UI/UX of a marketplace application that meets user needs and achieves a high level of usability. This study aims to design the UI/UX of the Kiddy Rent application, a marketplace specifically created for renting children's equipment and toys, using the User-Centered Design (UCD) approach to ensure that the final solution is tailored to user needs. The UCD stages applied include Understanding the Context of Use, Specifying User Requirements, Producing Design Solutions, and Evaluating Against Requirements. The resulting prototype was evaluated using two methods, namely Heuristic Evaluation and Usability Testing based on the ISO 9241-11 standard, by applying the System Usability Scale (SUS) to measure satisfaction. The evaluation results show that the application obtained a SUS score of 85.5, which is categorized as "Excellent", and entered the B grade with an acceptance level of "Acceptable". These findings indicate that the developed design not only meets user expectations but also has strong potential to provide an effective, efficient, and satisfying experience in the digital rental process.

Abstract

This study develops a Decision Support System (DSS) to assist in selecting the best employees by combining the Analytical Hierarchy Process (AHP) and Simple Additive Weighting (SAW) methods. Manual employee evaluations often result in subjectivity and bias, potentially impacting fairness and strategic HR planning. Therefore, a structured and objective evaluation system is crucial to enhance decision-making accuracy. AHP is applied to determine the weight of each evaluation criterion through pairwise comparisons and consistency analysis, ensuring reliable and valid weight values. These weights are then used in the SAW method to normalize employee performance scores and compute the final rankings. The DSS is built using the Extreme Programming (XP) methodology, emphasizing iterative development and active user feedback to ensure usability and functionality. The evaluation process is based on five benefit-type criteria: Innovative, Creative, Experimental, Agile, and Visionary. Results indicate that Employee 2 achieved the highest final score of 95.58, and was selected as the best employee. Black-box testing was conducted to validate the system’s functionality, and all modules such as employee data input, criteria management, score computation, and ranking display performed correctly. This DSS promotes fairness, transparency, and accountability in performance evaluation and provides a scalable framework that can adapt to organizational needs. Future enhancements may include integrating data visualization and expanding criteria dynamically. Overall, the system supports strategic human resource decisions and ensures objective evaluations through a reliable and systematic approach.
