Abstract

Bus is one of favorite transportation used in Indonesia. The comfort aspect of passenger seat of the economy class bus is still not  a top priority in the bus transportation services. The design of economy class bus seats is still based on experimental results, so that the design does not match the body shape (anthropometry) of Indonesian people. Based on a survey conducted by the research team found that the design of the economy class bus seat is not comfortable for the posture of the people of Indonesia. In this research has been designed design of bus seat ergonomically using Ergonomic Function Deployment (EFD) method. By using Ergonomic Function Deployment (EFD) method, the design of ergonomic economy class bus passenger seat is obtained. The design of the ergonomic chair is given the following dimensions of the height of the backrest is 956 mm, the holder length of is 370 mm, the width of the holder is 457 mm, the length of the armrest is 267 mm, the height of armrest is 89 mm, seat height is 349mm.
