Abstract
PT Cipta Oggi Furindo is a manufacturing company that produces various types of knock down furniture, such as office desks, cabinets, and television stands, with particle board as the main raw material. The company faces problems in inventory control that cause warehouse overcapacity and high inventory costs. This study aims to optimize inventory control by considering limited warehouse capacity to minimize total inventory costs. In the initial condition, the total space requirement exceeds the warehouse capacity. After optimization using the Lagrange Multiplier method, the space requirement is 128.59 m³, thus fulfilling the warehouse capacity. The total inventory cost using the Lagrange Multiplier method is Rp 61,349,841,- lower than the company's method of Rp 64,882,040,-, resulting in savings of Rp 3,532,199,- or 5.45%. This study shows that the Lagrange Multiplier method is effective in overcoming capacity limitations, optimizing order sizes, and minimizing inventory costs. The optimal order size for the next one-year period is 425 sheets of 25 mm particle board, 629 sheets of 15 mm particle board, and 1,926 sheets of 12 mm particle board.
