The digestive system plays an important role in maintaining the immune system. Gastrointestinal problems in developing countries, including Indonesia, are generally diarrhea and gastritis due to high morbidity and mortality. Based on data from the Yogyakarta city health office in 2021, the incidence of diarrhea reached 270/1,000 while data from the Sleman district health office showed an increase in the incidence of diarrhea from 2017 to 2019 of 16% -17%. In Ngemplak, Donoharjo, Ngaglik, Sleman, DIY, based on the recap of the results of the posbindu health checks it was found that around 10% of the hamlet residents experienced digestive disorders including diarrhea and gastritis. Digestive problems are influenced by consumption patterns and the surrounding environment. There is still a lack of knowledge of residents about the importance of environmental hygiene and personal self being the main factor. The provision of knowledge and community counseling can be provided by groups of residents who are routinely involved in Posbindu activities, namely the cadres of Family Welfare and Empowerment (PKK). Based on this, the aim of the activity is to provide assistance, training, and counseling regarding digestive health to the PKK groups so that they can become initial counselors for residents regarding knowledge of digestive health and its disorders. The method of activity is periodic assistance and counseling to groups of PKK both offline and online by the community service team. Assistance and counseling are provided in the form of providing material regarding digestive health, digestive health disorders, causative factors and prevention. At the beginning of the activity a pretest was given to participants to find out the level of initial knowledge of PKK mothers on digestive health then continued with the counseling, mentoring and training process for participants periodically online and offline. At the end of the activity an evaluation was carried out a post test to find out the level of knowledge of the participants after receiving assistance to measure the level of knowledge of the participants. the results of the initial screening level of knowledge of 18 participants showed an average of 64.45 and experienced an increase in the average score on the post-test, namely 73.34. From the results of the paired t-test, the increase in participants' knowledge showed no significant difference (p>0.05).
