Increasing Labor Productivity by Reducing Waste Caused by Unnecessary Motions in Swine Fattening Farming Processes by Implementing ECDRS Principles in Loei Province
Main Article Content
Abstract
This research aimed at studying waste and its causal factors in swine production. The study proposed a way to increase labor productivity by reducing motion waste according to the Eliminate, Combine, Divide, Rearrange and Simplify (ECDRS) principles. Mixed methodology was used to conduct the study. Regarding the qualitative data, individual units of analysis were gathered via participant observation and in-depth interviewing. A target group of 18 people were selected using purposive sampling. Quantitative data were gathered using questionnaires and systemic sampling with a sample size of 101. Data analysis was conducted using a flow process chart, operations flow chart, causal factors, Integrated Definition (IDEF) process chart, and ECDRS principles. The study found that waste caused by unnecessary motion in the swine production process resulted in a work time of up to 57.04 minutes. Operator factors were found to be the strongest causal factor of motion waste. Labor productivity was measured at 63.16 units per hour worked. This study suggests a way to increase labor productivity, reducing the work period from 57.04 to 53.11 minutes. This will raise labor productivity to 66.11 units per hour worked. The researcher recommends swine farmers give importance to increasing labor productivity by reducing waste, which will in turn promote work efficiency.
