Application of Kansei Engineering Method and Quality Function Deployment (QFD) in Designing Motorcycle-Based Ride-Hailing Backrest

The development of a passenger backrest for motorcycle-based ride-hailing services is a vital innovation to enhance both comfort and safety, with a particular focus on female users. This study utilizes Kansei Engineering to capture the emotional and ergonomic needs of passengers, complemented by Quality Function Deployment (QFD), to transform these needs into actionable product specifications. By integrating anthropometric data specific to Indonesian women, the resulting design aims to provide optimal stability and comfort during travel. The analysis using the House of Quality (HoQ) framework prioritizes key attributes such as material strength, ergonomic dimensions, and cushion thickness, which are critical for user satisfaction. Despite its strengths, the study acknowledges limitations, including a small respondent sample and the exclusion of cost considerations from the design process. To address these gaps, future research is encouraged to include large-scale field trials, cost analysis, and the exploration of sustainable materials. The proposed design offers a promising solution to enhance passenger experience, reduce travel-related discomfort, and mitigate safety risks. This study underscores the potential of integrating Kansei Engineering and QFD methodologies to create user-centric innovations that can significantly contribute to the transportation industry's development.
