The service activity is carried out with the aim of providing health promotion in order to increase public knowledge about stunting prevention with high protein foods which is carried out in the form of virtual meetings. Online activities are carried out because they are in a pandemic condition where direct physical meeting activities are limited. This service, which is integrated with KKN, is implemented in Margajaya Village, Tanjungsari District and Sumedang Regency. Steps in implementing activities include online mentoring, developing health promotion content, workshops through virtual meetings, and monitoring and evaluation. The results of service activities can be seen from the knowledge among posyandu cadres. The knowledge of the Posyandu cadres in Margajaya Village regarding stunting is fairly good. This is shown by the initial pre-test of the activity with the average score obtained is 80.88 out of 19 executive representatives in each RW. However, critical elements such as stunting indicators are still not well understood by certain Posyandu cadres. After receiving education, this number increased to 100 on the post-test results. The process requires assistance for cadres regarding the use of virtual meeting technology so that they can actively participate in service activities. These results show that the use of virtual meeting technology can be performed fairly well with the use of applications such as Whatsapp, Zoom and Trello, so that it can help with health promotion activities during a pandemic.
