Micro, Small, and Medium Enterprises (MSMEs) play a central role in the national economy, including the Kentucky Crispy Mushroom Home Industry in Medan Sunggal, which has been operating for 13 years. However, several obstacles remain, particularly in financial record-keeping, operational efficiency, and less than optimal digital marketing. This Community Service program aims to strengthen partners' capacity through mentoring in accounting, operational management, and digital marketing. The methods used include an initial survey, counseling, training, and ongoing mentoring involving lecturers and students. Implementation of this program includes the provision of production equipment such as baglog steamers, deep fryers, and continuous sealers, systematic financial record-keeping training, digital promotion strategies, and rebranding the business as "Salwa Oyster Mushrooms" with modern packaging and marketing through e-commerce platforms. This program has proven to improve product quality, strengthen brand identity, and expand partners' market reach. Recommendations include continuous innovation and optimization of digital marketing to ensure the business's sustainability and competitiveness.
