Optimization of Fabric Production through Linear Programming to Maximize Profit of a Textile Industry

Abstract

This study aims at maximizing a business profit in a textile industry. By using a descriptive quantitative approach, the study was conducted in the district of Cikokol, Tangerang, Indonesia by collecting data from a textile company producing yarn and woven fabrics for the years 2016 until 2017. The data was analyzed by using linear programming to maximize a business profit. In its daily process, the company faced many problems or constrains in its production planning. Uncertain demand fluctuation has caused shortage or overproduction. Other problems are the constrain of raw materials, machine working hour, labour working hour, spindle hour per unit, loom hour per unit, and demand of products. The result of the study showed that the total profit earned by the company to produce 6.67 dozen (80 pcs) of T/C woven fabric is US$ 133.400. On the other hand, total profit to produce 6.67 dozen (80 pcs) of cotton fabric is US$ 100.050, with the assumption that the profit is in accordance with fixed objective and constrain function.
