Abstract
The textile and textile product industry plays an important role in supporting the needs of society, so proper management of raw material supplies is necessary to maintain a smooth production process. CV Hasta Ningrat is a company in the textile industry with Cloth Diaper AIO Regular as its highest demand product. The company faces raw material inventory control issues because its ordering policy is not integrated with actual needs and warehouse capacity, resulting in increased inventory costs. The objective of this study is to control raw material inventory in order to minimize total inventory costs. The methods used in this study are Lagrange Multiplier and Reorder Point (ROP). The results show that with a warehouse capacity of 15,064 m³, the optimal order quantity is 16 rolls of microfiber fabric, 22 rolls of microfleece fabric, and 21 rolls of PUL waterproof fabric, with reorder points of 7 rolls, 12 rolls, and 18 rolls, respectively. The application of these methods resulted in a total inventory cost of IDR 22.194.689, which is lower than the company's method of IDR 23.965.625, resulting in savings of IDR 1,770,963 or 7%. Thus, the application of these methods can improve the efficiency of raw material inventory control
