This research aims to apply the principles of ergonomics society in the design of rubber mitkrit rubber plantation. Step by step, starting from study to assess the suitability of the use of the current tyre mitkrit. Using a query of mitkrit tires and assess suitability of posture by RULA methods (Rapid Upper Limb Assessment) study found that 85 percent of the samples feel not satisfied in using mitkrit resin and the average of the scores of RULA's body left and right.Naradap that should be monitored and should be changed to work shortly. Researchers have made the design of rubber mitkrit rubber plantation farmer. Based on the measurement data, the proportion of body samples and evaluating abnormal index (Index Adnormality; AI) of a sample of 400 people found that the assessment of a sample of the items in question contain more values. The average score of RULA's body left and right, and evaluation of abnormal index (Index Adnormality; AI) of samples from very resistant until an issue is not.
