Abstract
Latar Belakang: Pengendalian persediaan yang tidak optimal dapat menimbulkan risiko kerusakan atau kedaluwarsa obat, dan kekosongan stok obat. Data instalasi farmasi RSUD R. Ali Manshur mencatat peningkatan jumlah obat kadaluarsa dari 103 item (19,76%) pada tahun 2024 menjadi 144 item (27,63%) pada tahun 2025. Peningkatan ini diduga disebabkan oleh proses perencanaan pengadaan obat yang selama ini hanya mengandalkan metode konsumsi, padahal metode tersebut hanya akurat apabila data penggunaan obat bersifat lengkap dan konstan dari tahun ke tahun.
Tujuan: mengevaluasi efisiensi pengadaan obat kategori penting, utama, dan tambahan menggunakan pendekatan ABC-VEN yang diintervensi dengan metode EOQ
Metode: Penelitian ini adalah kuantitatif dengan Populasi seluruh item obat periode pemakaian Januari – Desember tahun 2025 dan besar sampel adalah seluruh item obat yang menjadi populasi.
Hasil: Kategori obat penting diperoleh penghematan sebesar Rp. 8.775.737 (1,52%). Obat utama menghasilkan efisiensi sebesar Rp. 39.058.265 (2,12%), obat tambahan memberikan penghematan sebesar Rp. 12.332.437 ( 1,92%). Hasil analisis statistik menggunakan uji Wilcoxon Signed-Rank Test memiliki nilai signifikansi sebesar 0,000 (p < 0,05) menunjukkan terdapat perbedaan yang bermakna antara nilai persediaan obat sebelum dan sesudah penerapan metode EOQ
Kesimpulan: Kombinasi metode ABC-VEN dan EOQ terbukti mampu meningkatkan efisiensi pengelolaan persediaan obat secara signifikan di Instalasi Farmasi RSUD R. Ali Manshur Tuban.
================================================================================================
Background: Suboptimal inventory control can create risks of drug damage or expiration, as well as drug stockouts. Data from the pharmacy installation of RSUD R. Ali Manshur recorded an increase in the number of expired drugs from 103 items (19.76%) in 2024 to 144 items (27.63%) in 2025. This increase is suspected to be caused by the drug procurement planning process, which has so far relied solely on the consumption method, even though this method is only accurate when drug usage data is complete and constant from year to year.
Aims: To evaluate the efficiency of procurement for essential, vital, and non-essential (auxiliary) drug categories using the ABC-VEN approach combined with the EOQ (Economic Order Quantity) method
Methods: This was a quantitative study with a population consisting of all drug items used during the January–December 2025 period, and the sample size comprised all drug items in the population.
Results: The essential (E) drug category achieved savings of Rp. 8.775.737 (1.52%). The vital (V) drug category produced efficiency gains of Rp. 39.058.265 (2.12%), and the non-essential (N) drug category yielded savings of Rp. 12.332.437 (1.92%). Statistical analysis using the Wilcoxon Signed-Rank Test showed a significance value of 0.000 (p < 0.05), indicating a meaningful difference between drug inventory values before and after implementation of the EOQ method.
Conclusion: The combination of the ABC-VEN and EOQ methods has been proven to significantly improve the efficiency of drug inventory management at the Pharmacy Installation of RSUD R. Ali Manshur Tuban
