Abstract

PT Petrokopindo Cipta Selaras faces challenges related to its production facility layout, resulting in relatively long material handling distances and potential conflicts in heavy equipment movement paths. This study aims to redesign the facility layout using the Systematic Layout Planning (SLP) approach. The methods employed include material handling distance analysis, From-To Chart (FTC), Activity Relationship Chart (ARC), and Activity Relationship Diagram (ARD). The results indicate a total material handling distance of 534.37 meters with a material transfer time of 10.63 minutes. The proposed layout improvement was developed by rearranging facility positions based on the degree of activity relationships to create a more efficient and organized material flow. This proposed layout is expected to improve material handling efficiency, minimize potential conflicts in heavy equipment movement and enhanced the overall production process.

Abstract

CV. XYZ is a company that produces household appliances made from Oriented Polypropylene (OPP) plastic pellets. The company is experiencing an excess of raw material inventory due to orders still being based on estimates without considering actual production needs. In 2025, the average remaining inventory reached 4,020 kg with an estimated storage cost of Rp12,288,885 per year. This condition resulted in high storage costs and inefficiencies in inventory management. This study aims to develop a production schedule using the Run Out Time (ROT) method as the basis for determining raw material needs, as well as to determine optimal inventory control using Economic Order Quantity (EOQ), safety stock, and reorder point. The research results show that the ROT scheduling produces a total of 412,508 pcs from April to June 2026. The EOQ method results in an optimal order quantity of 5,447 kg per order, a safety stock of 3,731 kg, and a reorder point of 5,091 kg. The total inventory cost using the EOQ method is Rp4,167,928, which is 31.8% lower than the company's policy of Rp6,115,000, resulting in savings of Rp1,947,072.
