Abstract

PT Pupuk Kujang, as one of Indonesia’s national fertilizer producers, faces inventory accumulation problems of NPK fertilizer in warehouses due to an imbalance between production capacity, storage capacity, and seasonal market demand. Excessive stockpiling exceeding standard storage limits, reaching up to 40 stacks, leads to increased operational costs and product damage risks of up to 20–30 percent, thereby reducing operational efficiency. This study aims to analyze the management of NPK fertilizer accumulation in warehouses and to determine optimal production scheduling and storage capacity policies through simulation methods and sensitivity analysis. The research applies a system dynamics approach using Causal Loop Diagram (CLD) and Stock Flow Diagram (SFD) models developed with AnyLogic software, complemented by supply chain simulation using SCM Globe. The study utilizes secondary data on NPK fertilizer production and distribution at PT Pupuk Kujang from 2015 to 2017. Simulation results indicate that inventory accumulation is primarily caused by inflexible production schedules that do not adequately adjust to seasonal demand fluctuations influenced by planting cycles and weather conditions. Sensitivity analysis results show that the scenario with a warehouse capacity of 25 stacks represents the most optimal condition, as it significantly reduces inventory buildup without disrupting distribution activities. This study recommends implementing more adaptive production scheduling and optimizing warehouse capacity and distribution systems to enhance operational efficiency and minimize the risk of product damage.

Abstract

The food industry, particularly the cookie sector, is growing rapidly as lifestyles evolve and consumers increasingly seek practical, innovative, and high-quality products. Using the TOWS analysis approach, this study aims to evaluate J&C Cookies’ marketing strategies in addressing competition within the cookie industry. The method used is qualitative descriptive, utilizing secondary data from company documents, marketing literature, and information on business strategies to examine the company’s internal and external aspects. Data analysis was conducted through data reduction, followed by the creation of a TOWS matrix to generate alternative marketing strategies. To enhance the company’s competitiveness in both local and international markets, the developed strategies include enhancing product reputation during festive occasions, creating new product variations, and expanding market distribution. These strategies are expected to strengthen J&C Cookies’ competitiveness in both local and global markets
