Abstract
The distribution of non-subsidized fertilizer plays a crucial role in supporting the sustainability of agricultural production. PT XYZ faces distribution challenges such as fluctuations in demand, seasonal demand, and system capacity mismatches that could potentially cause delivery delays. This study aims to examine the performance of non-subsidized fertilizer distribution at PT XYZ and to analyze a dynamic system model to improve distribution performance. The methods used include descriptive analysis and dynamic systems analysis through the development of a Causal Loop Diagram (CLD) and a Stock and Flow Diagram (SFD), model validation, and policy simulation using Vensim PLE. The results show that distribution performance is influenced by the interaction between fluctuating demand particularly from March to June and is affected by raw material inventory, production, finished goods inventory, and distribution. Seasonal demand patterns occur in January, May, November, and December. The developed model has a MAPE value of 0.03%, indicating that it is capable of representing the company’s actual conditions. The variables used for the simulation were Shipments, Queues, and Delivery Lead Time. Based on the simulation results, Scenario 1 is the recommended scenario because controlling non-PO orders has been shown to reduce distribution queues and shorten delivery lead times. Therefore, the company needs to implement controls on non-PO orders through quota restrictions, order fulfillment scheduling, and stock allocation to improve distribution performance.
