PENGENDALIAN ANTIBIOTIK BERDASAR METODE KONSUMSI ABC DENGAN PENERAPAN MINIMUM-MAXIMUM STOCK LEVEL TERHADAP EFISIENSI PERSEDIAAN FARMASI RUMAH SAKIT

Inefficient planning and control of drug supplies, apart from causing shortages or excess stocks, can also lead to inefficiency in hospital operating costs. This study aims to determine the effect of applying the Minimum-Maximum Stock Level (MMSL) method on the efficiency and effectiveness of drug supply in the Pharmacy Installation of RSU. Sanggau Medical Center. The sample group of class A antibiotics from the ABC consumption method as many as 22 types of drugs were taken purposively from retrospective data from January - June 2021, and applied the MMSL method prospectively in October - December 2021. Data analysis was carried out on inventory values, month-stock, and ITOR (Inventory Turn Over Ratio) before and after the application of the MMSL method using the Wilcoxon Signed Rank Test statistical test.The results of statistical tests showed the effect of applying the MMSL method to the month-stock ratio of the antibiotic group before the intervention was 2.87 and after the intervention was 2.03 with a p value of 0.021 (p <0.05). While the ITOR value before the intervention was 13.73 times/year and after the intervention was 19.16 times/year with p value = 0.006 (p<0.05). Although it did not show a significant difference in the inventory value of the antibiotic group between before the intervention (Rp. 62,497,441,) - and after the intervention (Rp. 54,072,358,-), with p value = 0.236 (p>0.05), but shows an efficiency of 13.48%. The application of the MMSL method has a positive impact on increasing the efficiency of drug control in hospitals by decreasing the inventory value and month-stock ratio, as well as increasing ITORPerencanaan dan pengendalian  persediaan obat yang tidak efisien selain dapat menyebabkan kekurangan atau kelebihan stok, juga dapat menyebabkan inefisien dalam biaya operasional rumah sakit. Penelitian ini bertujuan untuk mengetahui pengaruh penerapan metode Minimum-Maximum Stock Level (MMSL) pada efisiensi dan efektifitas persediaan obat di Instalasi Farmasi RSU. Sentra Medika Sanggau. Sampel kelompok obat antibiotik golongan A dari metode konsumsi ABC sebanyak 22 jenis obat diambil secara purposive dari data retrospektif bulan Januari - Juni 2021, dan dilakukan penerapan metode MMSL secara prospektif pada  bulan Oktober - Desember 2021. Dilakukan analisa data nilai persediaan, month-stock, serta ITOR (Inventory Turn Over Ratio) sebelum dan sesudah penerapan metode MMSL menggunakan uji statistik Wilcoxon Signed Rank Test. Hasil uji statistik menunjukkan pengaruh penerapan metode MMSL terhadap rasio month-stock kelompok antibiotik sebelum intervensi sebesar 2,87  dan sesudah intervensi 2,03 dengan nilai p = 0,021  (p<0,05).   Sedangkan nilai ITOR sebelum intervensi 13,73 kali/tahun dan sesudah intervensi 19,16 kali/tahun dengan nilai p = 0,006 (p<0,05). Meskipun tidak menunjukkan perbedaan yang bermakna pada nilai persediaan kelompok antibiotik antara sebelum intervensi (Rp. 62.497.441,)-  dan sesudah intervensi (Rp. 54.072.358,-), dengan nilai p = 0,236  (p>0,05), namun menunjukkan efisensi sebesar 13,48%. Penerapan metode MMSL memberikan dampak positif terhadap meningkatnya efisiensi pengendalian obat di Rumah Sakit dengan menurunnya nilai persediaan dan rasio month-stock, serta meningkatkan  ITOR
