Decreasing Musculoskeletal Complaints by Developing Product Design based on Ergonomics Participatory [ ]


The farming tools are vary, but nevertheless there are still some design of farming and building tools only consider the function but do not consider the wants and needs of users. Farmer are given product that are ready to use produced by large industry while construction workers only hammering the nail using ready to use hammer every day. Some tools only consider the function and have not adjusted to anthropometry of hands so that there are potential of force postures in operating, handle is not comfortable, early Complaints frequently happen when operating tools which is signed by spontan rest. Using of tools which does not consider the wants of users will effect to increase of postural stress of workers. Therefore design that considering the wants and needs of users by using participatory ergonomic approach is needed. This research is an experimental research using the post test only control group design because population of farmer considered homogen. Subjects totaled 46 are chosen randomly. Musculoskeletal complaints are measured by questionnaire Nordic Body Map (NBM). Result of questionnaire are compared and analyzed. Result shows that there is meaningful decrease between average score of musculoskeletal complaints when using conventional sickle with new design of sickle, but in use of hammer, there is no meaningful decrease because the change is only 3.681%. Redesign of tools based on user need could decrease musculoskeletal complaint as 15.517%
