Pengelolaan obat di puskesmas sangat penting dalam menjamin ketersedian dan keterjangkauan pelayanan obat yang efektif, efesien dan rasional. Kekosongan stok obat dapat mengindikasikan buruknya manajemen persediaan dan mengurangi kualitas pelayanan kesehatan. Untuk mencegah terjadinya kekosongan stok obat, maka perlu dilakukan evaluasi dan penentuan stok optimum persediaan obat di Puskesmas Kecamatan Ciracas. Metode yang digunakan adalah kuantitatif deskriptif observasional, dengan menggunakan data dari Lempar Pemakaian dan Lembar Permintaan Obat (LPLPO). Analisis data dilakukan menggunakan Microsoft Excel untuk menghitung stok optimum. Hasil evaluasi dan penentuan stok optimum obat melibatkan stok kerja, stok selama waktu tunggu dan stok pengaman. Perhitungan evaluasi stok optimum untuk tahun 2022 dan penentuan stok optimum tahun 2023 berbeda karena terjadi perpanjangan waktu tunggu pemesanan obat hingga empat minggu karena kelangkaan obat di distributor. Namun, kekurangan stok obat dapat diatasi melalui peminjaman obat dari puskesmas lain. Penetapan stok optimum dapat membantu dalam upaya perbaikan kondisi manajemen logistik obat dan pengendalian stock out obat di Puskesmas Kecamatan Ciracas.

Effective drug management in puskesmas (community health centers) is crucial to ensure the availability and accessibility of effective, efficient, and rational drug services. Drug stockouts can indicate poor inventory management and compromise healthcare quality. To prevent drug stockouts, an evaluation and determination of optimal drug stock levels were conducted at Ciracas Subdistrict Community Health Center. A quantitative descriptive observational method was employed, utilizing data from the Drug Usage and Request Form (LPLPO). Data analysis was performed using Microsoft Excel to calculate optimal stock levels. The evaluation and determination of optimal drug stock involved working stock, stock during waiting time, and safety stock. The calculation of optimal stock evaluation for 2022 and the determination of optimal stock for 2023 differed due to an extension of the drug ordering waiting time to four weeks caused by drug shortages at distributors. However, drug stock shortages were mitigated through borrowing drugs from other health centers. Establishing optimal stock levels can aid in improving drug logistics management and controlling drug stockouts at Ciracas District Community Health Center.
