Abstract

This paper aims to design an innovative tofu pressing tool using the Quality Function Deployment (QFD) to increase the productivity of tofu in Small and Medium-sized Enterprises (SMEs). A case study was carried out at the Wardi Tahu enterprise in Indonesia. The QFD method was adopted in this study to integrate the customer’s needs into the design process for the tofu press device. The House of Quality (HoQ) was developed to determine the relationship between technical characteristics and the customer's needs to obtain the design decision for the tofu pressing device. The determination design of the tofu press tool resulted in an innovative pneumatic system: tofu mould covers with perforated plates, removable tofu mould covers, corrosion-resistant materials, electric actuators, simple switching sys-tem, hygienic, modular design, formability and machinability, and easily accessible components. As a result, in this study, a pneumatic system tofu pressing machine has advantages over a manual tool, such as no longer need to lift a bucket filled with water as ballast, being easy to operate, being safe when operating, and simple, the tool can press faster, corrosion resistant and hygienic material of tool, easy to clean tool, increase the amount of production and hygiene process of tofu production.
