ABSTRAK
Kelebihan persediaan yang terjadi di UD. KS PRO sepanjang tahun 2023 telah menimbulkan kerugian finansial yang signifikan akibat tingginya biaya penyimpanan, yang mencerminkan adanya ketidakefisienan dalam pengelolaan persediaan. Permasalahan ini diidentifikasi sebagai akibat dari belum optimalnya sistem pengendalian persediaan yang diterapkan. Penelitian ini dilakukan untuk mengatasi isu tersebut dengan mengaplikasikan dua metode pengendalian persediaan, yaitu Periodic Review dan Continuous Review. Melalui penerapan simulasi Monte Carlo, permintaan dapat diproyeksikan secara lebih akurat, sehingga parameter kebijakan seperti titik pemesanan ulang, stok maksimum, dan jumlah pemesanan dapat ditentukan secara lebih efisien dan tepat sasaran. Hasil penelitian menunjukkan bahwa metode Continuous Review (s, S) lebih unggul dibandingkan Periodic Review, karena mampu menurunkan total biaya persediaan hingga 78,16% serta memberikan kontrol yang lebih responsif terhadap fluktuasi permintaan dan risiko overstock maupun stockout. Dengan demikian, metode Continuous Review direkomendasikan untuk diterapkan oleh perusahaan yang bergerak di sektor produksi dan distribusi, guna meningkatkan efisiensi operasional dan memperkuat daya saing dalam menghadapi dinamika pasar yang kompetitif.
ABSTRACT
The excess inventory that occurred at UD. KS PRO throughout 2023 has caused significant financial losses due to high storage costs, reflecting inefficiencies in inventory management. This issue was identified as a result of the suboptimal inventory control system being implemented. This research was conducted to address the issue by applying two inventory control methods, namely periodic review and continuous review. Through the application of Monte Carlo simulation, demand can be projected more accurately, allowing policy parameters such as reorder point, maximum stock, and order quantity to be determined more efficiently and precisely. The research results show that the Continuous Review (s, S) method is superior to the Periodic Review method, as it can reduce total inventory costs by up to 78.16% and provide more responsive control over demand fluctuations and the risks of overstock and stockout. Therefore, the continuous review method is recommended for implementation by companies in the production and distribution sectors in order to improve operational efficiency and strengthen competitiveness in facing the dynamics of a competitive market.
