Abstract

This study aims to redesign the raw material yarn warehouse layout at PT. XYZ using the Class Based Storage method to improve storage and retrieval efficiency. The main problem identified in the warehouse is random item placement, resulting in relatively long retrieval times of approximately 10–15 minutes per pallet. This research applies a descriptive quantitative approach using a case study method. The data used consists of inbound, outbound, and inventory records of yarn raw materials from November 2024 to April 2025. The analysis was conducted using the FSN (Fast Moving, Slow Moving, and Non-Moving) method through the calculation of consumption rate and average stay, combined with ABC classification to determine storage priority. The results show that 9 types of yarn are classified as Class A, 11 types as Class B, and 11 types as Class C. Based on this classification, a new warehouse layout was designed by placing Class A items near the input-output area, Class B items in the middle area, and Class C items in the back area of the warehouse, thereby improving storage efficiency and reducing retrieval time.

Abstract

Ineffective spare part inventory planning may lead to supply delays and reduced compliance with lead time supply key performance indicators (KPIs). This study aims to implement the Collaborative Planning, Forecasting, and Replenishment (CPFR) method in spare part inventory planning at PT XYZ and to compare lead time supply performance before and after the implementation of the CPFR method. This research utilizes spare part usage data from January to June 2025, focusing on fast-moving spare parts. Demand forecasting is conducted using an error forecasting approach with the moving average method. Forecast accuracy is evaluated using the Mean Absolute Deviation (MAD) and Mean Absolute Percentage Error (MAPE). Furthermore, inventory planning is carried out through the calculation of safety stock and reorder point (ROP) as the basis for determining replenishment decisions. The results indicate that the simulated implementation of the CPFR method provides a more structured and anticipative inventory planning process. The comparison of performance before and after the application of CPFR shows an improvement in lead time supply compliance with the established KPIs. Therefore, the CPFR method has the potential to support improved spare part inventory planning performance at PT XYZ.

Abstract

PT XYZ, perusahaan manufaktur tekstil, menghadapi kendala rendahnya efisiensi tata letak fasilitas yang ditandai dengan jarak perpindahan material yang jauh (mencapai 73,5 meter antara stasiun Sizing dan Weaving A) serta rendahnya utilisasi ruang aktual (34,4%). Kondisi ini menyebabkan tingginya waktu tunggu (idle time) dan beban operasional. Penelitian ini bertujuan merancang ulang tata letak fasilitas untuk meminimalkan jarak perpindahan material, menekan biaya operasional, dan meningkatkan produktivitas melalui integrasi metode Systematic Layout Planning (SLP) dan algoritma BLOCPLAN. Metodologi diawali dengan normalisasi luas area secara bottom-up, mencakup dimensi mesin, ruang pergerakan operator, penumpukan Work-In-Process (WIP), dan area keselamatan. Kedekatan antar-departemen kemudian dipetakan menggunakan Activity Relationship Chart (ARC) pada tujuh departemen produksi utama. Hasil iterasi BLOCPLAN menetapkan Layout 10 sebagai usulan terbaik dengan Adjacency Score 0,72. Implementasi tata letak ini berhasil meningkatkan efisiensi jarak perpindahan sebesar 37,64% (dari 1.898,5 m menjadi 1.184 m per hari). Secara kuantitatif, optimasi ini berdampak pada penghematan waktu perpindahan sebesar 28,05% dan penurunan Ongkos Material Handling (OMH) sebesar 37,65%. Perancangan ulang ini secara efektif mereduksi pemborosan pergerakan dan waktu tunggu, memberikan peningkatan produktivitas yang signifikan bagi PT XYZ
