Community Service Activities (CSA) were carried out in the Cipulir sub-district. The activity participants are MSMEs who live in Cipulir sub-district. The people at the location generally work as traders and small industries. MSMEs often face problems with shortages or excess supplies which have the impact of hampering business activities. The causes of shortages or excess inventory include: a) MSME actors do not forecast sales, so MSME actors only order inventory according to previous order history. This causes ambiguity between the production plan and the raw material requirements plan, which is the reference for purchasing inventory, b) the absence of safety stock, which is useful for guarding against the possibility of stock outs, c) the absence of clear inventory management, with no there is evidence of inventory recording, as well as inventory control. Based on an analysis of the situation faced by partners, the Community Service Team intends to provide solutions to partner problems by increasing knowledge and understanding regarding inventory management for MSMEs. The method used in this activity is sharing sessions and discussions, which are then given training related to inventory management. Then the activity continued with questions and answers and case study simulations. The results of the evaluation showed that most participants understood the material presented. The evaluation results also illustrate that all participants felt they had benefited from this activity, and were satisfied with the implementation of this activity.
