Abstract

English

This research discusses about the comparison of raw material inventory control CV. Dirga Eggtray Pinrang. It starts with forecasting inventory for the next 12 periods using variations of the time series forecasting method, where the linear regression method provides accurate forecasting results with a Mean Absolute Percentage Error (MAPE) value of 1,9371%. The probabilistic models of inventory control used are the simple probabilistic model, Continuous Review System (CRS) model, and Periodic Review System (PRS) model. The CRS model with backorder condition is a model that provides the minimum cost of Rp. 969.273.706,20 per year compared to another probabilistic model with the largest difference of Rp. 1.291.814,95 per year, with the optimum number of order kg, reorder level kg, and safety stock kg.

Bahasa Indonesia

Pada penelitian ini membahas tentang perbandingan model pengendalian persediaan bahan baku CV. Dirga Eggtray Pinrang. Diawali dengan melakukan peramalan persediaan untuk 12 periode kedepan menggunakan beberapa variasi metode peramalan time series, dimana metode regresi linear memberikan hasil peramalan yang akurat dengan nilai nilai Mean Absolute Percentage Error (MAPE) sebesar 1,9371%. Model probabilistic pengendalian persediaan yang digunakan adalah model probabilistic sederhana, model Continuous Review System (CRS) dan model Periodic Review System (PRS) pada kondisi pemesanan ulang dan kehilangan penjualan. Model CRS pada kondisi pemesanan ulang merupakan model yang memberikan biaya total paling minimum yaitu sebesar Rp. 969.273.706,20 per tahun dibanding model probabilistic lainnya dengan selisih terbesar yaitu Rp. 1.291.814,95 per tahun dengan jumlah pemesanan optimum q0*=9072,65 kg, reorder level r*=14621,74 kg dan besarnya safety stock ss=164,70 kg.
