This activity aims to develop and implement an information application that can strengthen digital marketing strategies for oyster mushroom and citrus processed products for farmers in Danda Jaya Village, Rantau Badauh Sub-District, Barito Kuala Regency, South Kalimantan Province. Based on the initial survey and interview to the farmers, an information application was built that offers informative content, product promotion, and direct interaction with consumers through various features such as product information, recipes, and online ordering services. The implementation of this application is expected to increase visibility and consumer engagement, as well as expand the market reach for processed oyster mushroom and citrus products. Evaluation of application effectiveness is carried out through monitoring digital marketing performance, analyzing user data, and feedback from application users. It is hoped that the results of this activity can contribute to the development of digital marketing strategies for the food industry, especially in increasing market penetration and strengthening sales of processed oyster mushroom and orange products so that they can contribute to improving the economic welfare of the surrounding community.
