Abstract

The automotive industry requires fast and accurate sales services, particularly in vehicle credit simulation processes. At Mazda dealerships, credit simulations are still commonly conducted using conventional tools such as printed installment tables or static PDF documents, which often cause delays and calculation errors. This study aims to design and develop a mobile-based vehicle credit simulation application using the Human-Centered Design (HCD) approach and the Flutter framework. The HCD method was implemented through the inspiration, ideation, and implementation stages to ensure that the application meets the real needs of Mazda sales representatives. The application supports flexible credit calculations based on vehicle on-the-road price, down payment, loan tenor, interest rate, and insurance schemes, including All Risk and combination insurance. Usability testing results show that the proposed application significantly improves calculation speed, accuracy, and overall user experience compared to conventional methods. Therefore, the application effectively supports sales performance, minimizes human error, and enhances professionalism in automotive sales services.

Abstract

The rapid development of information technology has encouraged organizations to improve the quality of information technology services in order to support the effectiveness and efficiency of business processes. PT Teknologi Informatika Solusindo, as a company engaged in information technology services, faces several challenges in managing helpdesk services, including manual ticket recording, delays in handling user complaints, difficulties in monitoring problem resolution status, and a lack of transparency in service processes. These issues have the potential to reduce service quality and user satisfaction. This study aims to analyze and design a web-based helpdesk system that can improve report management effectiveness, accelerate problem resolution processes, and provide more accurate and integrated service information. The system development method used is the Prototype model because it facilitates continuous communication and evaluation with users, resulting in a system that better meets organizational requirements. Furthermore, software quality testing is conducted based on the ISO 25010 standard to ensure that the system satisfies quality aspects such as functional suitability, usability, reliability, performance efficiency, security, compatibility, and maintainability. The results of this study indicate that the designed web-based helpdesk system simplifies ticket management, improves service response time, facilitates monitoring activities, and supports decision-making through structured and well-documented information. Therefore, the developed system can serve as an effective solution for improving the quality of information technology services at PT Teknologi Informatika Solusindo.
