    WORK DESIGN AND ERGONOMICS ?

    The history started during the World War II when psychologists, physiologists, anthropologist, doctors, and egineers began to applied technology and human sciences together.

    Ergonomics : the study of the interaction between people andmachines and the factors that affect the interaction (Bridger,2003).

    Ergonomics : from the Greek words ergon (work) and nomos (law) (Dul and Weerdmeester, 2008).

    Ergonomics ~ Human Factors/Ergonomics (HFE)

    Work design/engineering : study of principles and techniques toestablish the best work design (human, materials, environment) optimal effectivity, efficiency, and productivity

    WORK DESIGN AND ERGONOMICS ?

    Ergonomics and work design goals to get optimal productivity along with health and safety

    Ergonomics remains one

    of main factors causinginjury/disease.

    PRODUCTIVITY AND COST

  • 8/10/2019 PKE 1. Desain Kerja Dan Produktivitas 2

    21/23

    WORK SPEED AND ERROR

    1. Two factors as productivityinput : - Amount/number of outputs

    achieved- Time needed to complete a

    job/task

    2. Productivity rate increasemust consider quality controlof the product.

    Work speed and error aregenerally correlated, considering: age, experience, ability

    WHAT IS WORK DESIGN ANDERGONOMICS ?

    The science of matching the job to the worker, and the product to theuser

    The scientific study of human work

    Fitting the task/job to the human

    Worker ? User/customer ?
