Indonesia merupakan negara dengan populasi muslim terbesar di dunia, yang mendorong pertumbuhan pesat industri fashion muslim. Namun, banyak perusahaan lokal menghadapi tantangan dalam perencanaan dan pengendalian persediaan bahan baku, khususnya akibat keterlambatan pengadaan impor yang menyebabkan kekosongan stok (stockout). Penelitian ini bertujuan untuk merencanakan dan mengendalikan persediaan bahan baku Voil Japan pada salah satu perusahaan fashion muslim di Jakarta Barat, khususnya untuk bahan baku produk hijab paris dengan kode warna PPP01, PPP02, PPP03, PPP04, dan PPP12. Penelitian ini menggunakan data periode Januari 2024 hingga Desember 2024 dengan menggunakan metode Wagner-Within Algorithm yang digunakan untuk memberikan solusi optimal dalam pengendalian persediaan bahan baku hijab paris. Hasil penelitian menunjukkan bahwa penerapan metode Wagner-Whitin Algorithm tertinggi terdapat pada bahan baku Voil Japan PPP01 sebesar Rp272.363.115. Nilai safety stock dan reorder point (ROP) pada Voil Japan PPP01 masing-masing sebesar 20,526 yard dan 603,831 yard. Sementara itu, nilai total persediaan dengan menggunakan metode Wagner-Within Algorithm terendah terdapat pada bahan baku Voil Japan PPP02 yaitu sebesar Rp190.769.621. Nilai safety stock dan reorder point (ROP) pada Voil Japan PPP02 masing-masing sebesar 10,625 yard dan 417,093 yard.

Indonesia has the largest Muslim population in the world, which drives the rapid growth of the Muslim fashion industry. However, many local companies face challenges in the planning and control of raw material inventories, particularly due to delays in imported procurement that lead to stockouts. This study aims to plan and control the inventory of Voil Japan raw materials at a Muslim fashion company in West Jakarta, specifically for hijab paris raw materials with color codes PPP01, PPP02, PPP03, PPP04, and PPP12. The study uses data from the period of January 2024 to December 2024, employing the Wagner-Whitin Algorithm method to provide optimal solutions in managing hijab paris raw material inventory. The results show that the highest total inventory cost using the Wagner-Whitin Algorithm was found in Voil Japan PPP01, amounting to IDR 272.363.115. The safety stock and reorder point (ROP) values for Voil Japan PPP01 are 20,526 yards and 603,831 yards, respectively. Meanwhile, the lowest total inventory cost was found in Voil Japan PPP02, amounting to IDR 190.769.621. The safety stock and reorder point (ROP) values for Voil Japan PPP02 are 10,625 yards and 417,093 yards, respectively.
