Abstract
NaOH merupakan senyawa kimia dengan alkali tinggi. Dalam proses produksi pupuk, NaOH berperan sebagai activator resin senyawa ion anion dan kation pada proses demineralisasi air untuk umpan boiler, Begitupun alur produksi pupuk yang diterapkan pada PT Petrokimia Gresik. Penelitian ini bertujuan untuk menganalisis persediaan pada gudang III berupa bahan penolong NaOH di PT Petrokimia Gresik. Metode yang digunakan adalah Economic Order Quantity (EOQ), dan Just In Time (JIT). Hasil penelitian mendapatkan bahwa penggunaan metode EOQ mampu menekan total biaya persediaan hingga 48,52% lebih rendah dari biaya yang diterapkan pada perusahaan, sedangkan metode JIT mampu menekan total biaya persediaan hingga di angka 73,89% lebih rendah dibandingkan dengan yang diterapkan kebijakan perusahaan. Sehingga metode JIT mampu melakukan saving yang lebih banyak untuk dialokasikan pada kebutuhan lain. Studi ini memberikan wawasan dan menambah keilmuan mengenai kajian efisiensi persediaan melalui pendekatan EOQ dan JIT.
NaOH is a chemical compound with high alkalinity, in the fertilizer production process, NaOH acts as an activator of anion and cation ion compound resins in the water demineralization process for boiler feed, as well as the fertilizer production flow applied to PT Petrokimia Gresik. This study aims to analyze inventory in warehouse III in the form of NaOH auxiliary materials at PT Petrokimia Gresik. The methods used are Economic Order Quantity (EOQ), and Just In Time (JIT). The results found that the use of the EOQ method was able to reduce total inventory costs up to 48.52% lower than the costs applied to the company, while the JIT method was able to reduce total inventory costs to 73.89% lower than those applied by company policies. So that the JIT method is able to save more to be allocated to other needs. This study provides insight and adds knowledge to the study of inventory efficiency through EOQ and JIT approaches.
