Jenis penelitian kuantiitatif, digunakan untuk mengkaji penerapan metode Economic Order Quantity (EOQ) dalam pengendalian persediaan bahan baku di Salsa Bakery Jepara. Hasil penelitian diperoleh jumlah persediaan optimal dengan metode Economic Order Quantity (EOQ) tepung terigu pada triwulan 4 tahun 2012 sebanyak 112 karung frekuensi 7 kali, persediaan pengaman 19 karung, melakukan pemesanan ulang (ROP) ketika persediaan di gudang tersisa 39 karung, total biaya sebesar Rp 2.308.133. Triwulan 1 tahun 2013 sebanyak 100 karung frekuensi 8 kali, safety stock 19 karung, reorder point 39 karung, total biaya Rp 2.499.363. Triwulan 2 tahun 2013 sebanyak 100 karung frekuensi 8 kali, safety stock 14 karung, reorder point 34 karung, total biaya Rp 2.533.428. Triwulan 3 tahun 2013 sebanyak 102 karung frekuensi 8 kali, safety stock 14 karung, reorder point 35 karung, total biaya Rp 2.562.375.
