Omax Application on a T-Shirt SME for Productivity Improvement

Abstract

Titik Terang Convection is a small industry (SME) that produces t-shirts. They have yet to be able to meet targets according to customer demand. The production activity from May to July 2022 shows the company’s completion rate is 95%. Failure to achieve this target causes a decrease in consumer satisfaction levels. Therefore, this research aims to determine the factors that influence productivity and provide suggestions for efforts that need to be made to increase company productivity. The method used to measure productivity is OMAX (Objective Matrix). These measurements showed that the main factor causing the company’s productivity not to be achieved was low production output, mainly due to inefficient work elements during the production process. This resulted in delays in finished products and decreased consumer satisfaction. Improvement was done by creating a flow process chart (FPC) so that less efficient work elements could be detected and corrected according to the initial chart. The results of this study show improvements by increasing productivity by up to 65% while reducing cycle time by 5.58%. This shows that OMAX can help to see the main factors of low productivity, and FPC supports re-engineering the work elements to make them more efficient.
