Pengendalian persediaan obat antibiotik di RS Puri Cinere menunjukkan belum adanya keseimbangan antara pembelian dengan pemakaian obat. sehingga perlu untuk dilakukan analisis pengendalian persediaan obat antibiotik di gudang medik RS Puri Cinere. Jenis penelitian ini adalah studi kasus untuk melihat pengendalian persediaan obat antibiotik yang memiliki nilai investasi paling besar pada periode Januari hingga Desember 2011. Penelitian ini memperlihatkan bahwa pengendalian persediaan obat antibiotik di Gudang Medik belum optimal walaupun kebijakan mengenai persediaan obat telah mendukung kegiatan pengendalian persediaan obat. Hal ini dapat dilihat dari belum ada perhatian khusus terhadap jenis persediaan obat antibiotik dengan analisis pareto berdasarkan nilai pemakaian dan investasi. Penentuan jumlah pemesanan belum menerapkan perhitungan Economic Order Quantity (EOQ). Perhitungan EOQ dalam menentukan jumlah optimal dapat meningkatkan efisiensi pada persediaan obat antibiotik sebesar Rp149.818.987,00. Penentuan nilai stok minimal masih berdasarkan asumsi darinilai pemakaian lalu. Nilai stok minimum saat melakukan pemesanan bervariasi antara 4-353 unit. Frekuensi pemesanan bervariasi antara 69-249 kali dalam satu tahun. Demand forecast belum dapat mendukung pelaksanaan pengendalian persediaan di Gudang Medik karena belum menggunakan peramalan sebagai pertimbangan dalam menentukan jumlah pemesanan obat. Rumah Sakit Puri Cinere telah mempunyai kebijakan berupa Standard Operating Procedure (SOP) yaitu ; prosedur perencanaan pembelian, penerimaan obat dari supplier, pendistribusian obat, alur invetorisasi dan Surat Keputusan (SK) tentang Standarisasi Obat dan Alkes. Kebijakan yang tertulis dalam SOP dan SK telah sesuai dengan panduan dari Kementrian Kesehatan. Penulis menyarankan Instalasi Farmasi perlu memberi perhatian pada perencanaan pembelian sebagai awal titik pengendalian persediaan antiobiotik. Sebaiknya Instalasi Farmasi mengendalikan persediaan obat antibiotik dengan penggunaan pareto untuk mempermudah pengendalian variasi jenis obat, perhitungan EOQ dimana biaya pemesanan dan penyimpanan dipertimbangkan dalam menentukan jumlah pemesanan, perhitungan ROP untuk menentukan batas stok minimum, dan penggunaan demand forecast sebagai informasi masukan perencanaan pembelian.
