Abstract

Spare parts inventory plays an important role in the smooth operation of a repair shop because it directly affects service time and customer satisfaction. However, stock determination often still depends on experience, which risks causing shortages of frequently needed parts or accumulation of rarely sold parts. This study aims to analyze spare part purchasing patterns and segmentation to support inventory management decision-making at CV. XYZ. The data used consists of spare part sales transactions from February to December 2024, totaling ±33,000 lines from approximately 7,543 transactions. The research process followed the CRISP-DM stages. Purchasing patterns were analyzed using association rule mining with the FP-Growth algorithm at a minimum support parameter of 0.01 and a minimum confidence of 0.25, resulting in 81 association rules. Spare part segmentation was performed using K-Means clustering with 3 clusters, which were then mapped into fast, slow, and no moving segments. Cluster 0 (fast) consisted of 114 items, Cluster 1 (slow) consisted of 176 items, and Cluster 2 (non) consisted of 39 items. The analysis results were implemented in a Streamlit dashboard to aid in interpretation and stock priority recommendations. Evaluation through interviews showed that the dashboard was deemed suitable for the workshop's operational needs and feasible for use as a decision support tool.
