摘要
库存控制是对工业生产过程中原材料库存数量进行管理的一项主要活动。PT. Pertamina RU II Dumai从事石油和天然气业务活动,在燃料生产过程中使用原油作为主要原料。初步观察发现,在2019-2020年期间,avtur燃料的需求不稳定,下降到54%,而柴油则上升到17%。因此,这对原油订单数量和库存管理都有影响。本研究旨在确定2019 - 2020年大流行疫情前后的最优库存量、安全库存量、再订货点以及原材料使用量的比例分析。提出了经济订货量(EOQ)方法,以最适合其需求的数量下订单。本研究结果表明,2019年和2020年采用EOQ方法采购的原材料数量分别为3,525,563,777桶和2,427,392.443桶。2019年的总安全库存为10031,979.39桶,而2020年为8,733,637.21桶。2019年的再订货点数量为3,035,881,925桶,2020年为2,321,768,481桶。对于这种原材料的经济采购量,发现原油的订单量在疫情发生后下降了31.1%左右。
ANALISIS PENGENDALIAN JUMLAH CRUDE OIL SEBELUM DAN SESUDAH PANDEMI COVID-19 DENGAN PENDEKATAN ECONOMIC ORDER QUANTITY
Inventory control is a main activity for managing the amount of raw material inventory of the industry production process. PT. Pertamina RU II Dumai which engaged in oil and gas business activities have used Crude Oil as the major raw material in the fuel production process. Based on preliminary observation, it was found that the demand for avtur fuel was unstable during the period 2019-2020, decreasing to 54% whereas diesel fuel increasing to 17%. Consequently, this has an impact on the number of Crude Oil orders and also the inventory management. This study aims to determine the optimal amount of inventory, safety stock, the reorder point, and the ratio analysis of the amount raw material used during the era before and after pandemic covid-19 situation 2019 to 2020. Economic Order Quantity (EOQ) approach is proposed to place orders in the amounts that best fit its needs. The results of this study indicate that the number of purchases of raw materials using the EOQ method in 2019 and 2020 amounted to 3,525,563,777 BBL and 2,427,392.443 BBL. Total safety stock in 2019 was 10,031,979.39 BBL, while in 2020 it was 8,733,637.21 BBL. The number of reorder points in 2019 was 3,035,881,925 BBL and in 2020 it was 2,321,768,481 BBL. Regarding to this economic purchase of raw material quantity, it is found that the order size of Crude Oil decreased around 31.1% after the pandemic hit.
