Perancangan dan Pengembangan Produk Flow Bottle Berdasarkan Kebutuhan Konsumen dengan Metode QFD

Abstract

Increasing public awareness of healthy lifestyles and the reduction of single-use plastic waste has encouraged the demand for practical, comfortable, and consumer-oriented drinking bottle products. This study aims to design and develop a Flow Bottle product based on consumer needs using the Quality Function Deployment (QFD) method. The research employed a quantitative descriptive approach, with data collected through questionnaires distributed to 17 respondents. The research stages included identifying the Voice of Customer (VoC), determining Customer Requirements, establishing Functional Requirements, and constructing a House of Quality (HOQ) to translate customer needs into technical product specifications. The results indicate that the most important consumer requirements are strong bottle material and leak-proof performance, each receiving an importance level of 94.1%, followed by ease of carrying (88.2%), affordable price (70.6%), and attractive design (58.8%). The HOQ analysis reveals that the primary priorities for product development are improving material quality and enhancing the leak-proof system, as these factors have the strongest relationship with customer requirements. Furthermore, the Customer Competitive Assessment shows that the Flow Bottle has competitive advantages in terms of affordability and leak resistance compared to competing products. This study demonstrates that the QFD method is effective in translating consumer needs into technical product characteristics, thereby enabling a more systematic, focused, and customer-oriented product development process.
