Abstract

PT. Kereta Api Indonesia (Persero) is a company engaged in the field of freight and human transportation services. At this time train passengers have complaints regarding the design of train passenger seats that are still not ergonomic. Based on this, it is necessary to design railroad passenger seats by taking into account aspects of consumer needs and anthropometric data. The purpose of this study is to provide a proposal for an ergonomic train passenger seat design in order to provide comfort when sitting with good passenger posture using the Ergonomic Function Deployment (EFD) method. The Ergonomic Function Deployment (EFD) method is a development of the Quality Function Deployment (QFD), namely by adding a new relationship between consumer desires and the ergonomic aspects of the product. The EFD method is used to make it easier during the design process, decision making is "recorded" in the form of matrices so that it can be re-examined and modified in the future, usually to find out whether the design results are ergonomic or not. Evaluation of work posture using REBA produces a score of 5 which is included in the medium risk level with the need for improvement in the form of further investigation and changes immediately. Based on the results of the passenger seat design using the Ergonomic Function Deployment (EFD) method, it is obtained that the passenger seat design improvement is in the form of seat back height 71.152 cm, seat back width 49.535 cm, seat base length 49.726 cm, seat base height 40.179 cm, and the addition of armrests with backrest height hand 18.663 cm.
