Abstrakt: Ergonomics is the study of the work people do, the environment and the tools they use to perform the work. Jowar roti or Jowar rotti is a flat and thin bread made from jowar (sorghum flour), very common in North Karnataka. The dough is prepared by mixing the hot water with jowar flour, and then the roti/rotti is spread on a stone by tapping using the palm. The present work focuses on identification of ergonomic deficiencies in the Jowar Roti (Sorghum flat bread) making units and associated problems of musculoskeletal disorders (MSDs), workstation design, postural issues and safety and health issues. Roti making is the most laborious and stressful process. Incorrect postures sustained (sitting on floor) for a long period of time while performing roti making activities gives rise to musculoskeletal problems. The study consists of selecting 30 workers randomly from 6 different units as working group and 30 women participated in the study as control group. Self reported Body Part Discomfort questionnaire was administered and the hand grip strength was measured before and after work. Rapid Upper Limb Assessment (RULA) was done on selected awkward postures from different activities. RULA results indicated (46.66%) postures in high risk and (33.34%) in medium risk. Statistical tests ANOVA between grip strength of two groups showed significant difference (F value - 94.52683, p < 0.01). CATIA V5 software was used for RULA analysis which indicated high risks (scores of 6 or 7). The workstation is redesigned and a standing workstation is modelled in CATIA V5 and RULA analysis for changed workstation indicated low to medium risks (scores of 3 or 4). The findings of the study highlights several environment and safety concerns for which suitable suggestions and recommendations are made to overcome the ergonomic and Occupational Health and Safety issues.
