Assessment of Performance and Ergonomics Analysis for Cassava Sieving Machine
Year: 2025
Type: article
Abstract: The study is focused on assessment of performance and ergonomic analysis for cassava sieving machine. To achieve this, determination of level of exposure of musculoskeletal discomfort using questionnaire analysis, performance evaluation of the existing and improved cassava sieving machine, determination of anthropometric characteristics of cassava processors, establishment of design dimensions were obtained and factored into the development of the improved sieving machine. ResultsofdatacollectedandanalysedrevealedthatadjustableSeatheightrangeof 37-47cm, machine height of 80cm, and width of 48cm obtained from anthropometric body analysis of cassava processors was adopted. Also, the result obtained for the existing sieve showed 69% efficiency, 0.42kg/min sieve capacity, while the improved sieve showed 2.1kg/min sieve capacity and 89% efficiency. Questionnaire analysis indicated that 80% of users preferred the improved sieve based on comfortability criterion while 20% preferred the existing sieve. Energy expenditure result of users obtained showed 3.87KJ/min and 2.8KJ/min for existing and improved sieve respectively.
