| dc.description.abstract | PT Intrafood Singabera Indonesia faces challenges in managing its ginger raw material
inventory due to the use of conventional inventory control methods. Throughout 2023,
the company recorded 107 procurement activities and experienced an excess inventory
of 115,550 kg, leading to high storage costs and operational inefficiencies. This study
focuses on designing an inventory planning system for ginger raw materials using the
Continuous Review System (CRS) method, based on projected demand for 2024. The
implementation of CRS, with an optimal order quantity (Q) of 36,562 kg, a reorder
point (ROP) of 9,916 kg, and a safety stock of 1,953 kg, successfully reduced the
total inventory cost from Rp 43.995.000 to Rp 12.893.515, while also decreasing the
order frequency to 32 times. Demand forecasting for ginger raw materials in 2024 was
conducted using the linear regression method, identified as the best-performing model.
The projected demand reached 1,472,210 kg, representing an increase of approximately
27% compared to the previous year. Based on this forecast, the CRS simulation for 2024
resulted in updated parameters of Q = 40,832 kg, ROP = 11,747 kg, and safety stock
= 1,588 kg. The total estimated inventory cost was Rp 14.340.278, with an ordering
frequency of 36 times—an increase of only around 11% despite the substantial rise in
demand. To ensure the practical applicability of CRS, this study assumes collaboration
with farmer associations equipped with cold storage facilities, allowing the company to
place periodic orders without absorbing the entire harvest at once. The CRS method
proves to be an effective and efficient strategy for sustainable inventory control. | en_US |
