Perencanaan dan Pengendalian Persediaan Produksi Crude Palm Oil dan Palm Kernel dengan Model Economic Production Quantity Multi Item (Studi Kasus : PT. Socfin Indonesia)

Abstract

Production is a process of converting input value into an output value where a continuous process occurs repeatedly over time so that the output obtained is in accordance with the design specifications that have been set based on the wishes of a market. Economic Production Quantity (EPQ) Multi Item or optimal production level is the quantity of products produced by minimizing the total cost of inventory, including production setup costs and storage costs on two or more items. In overcoming the shortage or excess, each company needs to do planning in controlling production so that there is no loss and no profit is achieved. In this study, demand forecasting is used and carried out to obtain an estimated value for the following year, for the forecasting method used based on historical CPO data is single exponential smoothing where the estimated amount of demand each year is 5,514,552 kg, while from historical PK data the forecasting method used is double exponential smoothing where the estimated amount of demand each year is 471. 072 kg, so that the number of production cycles (production run) in 12 months or one year is 2.7 cycles, so that the ideal EPQ value for one cycle of each item of goods is for CPO of 1,904,648.89 kg and PK of 174,471.111 kg with a production time of 5 days per cycle. By planning and controlling using EPQ Multi Item, the company will be able to minimize total costs by 21% each year.
