The Inspection Division is an important part of a business in the textile and textile product (TPT) industry, including PT. XYZ Purworejo which produces gray fabric with custom woven and construction because of the make to order (MTO) system. Currently, the textile industry is one of the sectors that is prepared to become a mainstay in the application of industry 4.0 in Indonesia. The growth of an industry is certainly accompanied by increasing demand, which creates demands for workers to achieve production targets. To fulfill this, it is important for companies to pay attention to the operator's workload in order to have a maximum level of performance. The purpose of this study was to determine the workload of the Inspection Division operator at PT. XYZ and proposed improvements that can be implemented by the company to increase productivity. The results showed that the inspection division operators had an average workload of 1,216 (overload). To overcome this, additional operators, purchase of new machines, and preventive maintenance can be carried out.
