Reog is one of the distinctive cultural practices of Ponorogo. Typically, this art is performed in an open space with many entertainers. Reog Ponorogo enthusiasts will primarily purchase trinkets and handicrafts. Numerous artisans in Reog Ponorogo are members of Micro, Small, and Medium-Sized Enterprises (MSMEs). However, because of the global Covid-19 pandemic, Reog Ponorogo artisans have encountered numerous challenges, beginning with the procurement of raw materials, and continuing through the production process and marketing. This even put them out of business with the Reog artisans. A knowledge Management System (KMS) is one of the technologies that can be utilized to surmount the problem under these conditions. Knowledge Management System (KMS) is a centralized database utilized to organize, store, and disseminate organizational knowledge with employees and customers. In this study, the KMS was developed to assist MSME actors in acquiring information and knowledge concerning MSME Products in Reog Ponorogo Handicrafts. Currently, information about Reog Ponorogo is widely available in print and digital media, but it is not governed by a comprehensive information management system. Therefore, building KMS for Reog Ponorogo Handicraft MSMEs is still necessary. In this research, a modified variant of the Knowledge Management System Life Cycle (KMSLC) was used to develop the KMS. This research was conducted in multiple phases, including infrastructure evaluation, team formation, knowledge capture, and KMS design. This study contributes to the creation of a knowledge management system for MSME Reog Ponorogo artisans based on the life cycle of knowledge management systems. This study's findings serve as the basis for the Reog Ponorogo craft knowledge management system. Further research can concentrate on developing the Reog Ponorogo UMKM KMS on Android and iOS mobile phones, enhancing the KMS user interface, and granting both experts and UMKM administrative access to the KMS.
