ABSTRACT The nutritional problems of toddlers and children in the Anak Dalam Tribe are malnutrition and stunting. One of the factors is the lack of a sanitary and healthy living behavior in the community. The condition of environmental health and environmental sanitation that meets the requirements is only 50%, the decline in the behavior of mothers in monitoring the growth and development of children at the Posyandu and monitoring of nutritional status in schools tends not to be carried out. It is necessary to educate the public regarding sanitary and healthy living behavior and monitoring the nutritional status of toddlers and school-age children in Nyogan Village. Community service activities are carried out through counseling activities for school children at SDN 238 and training for toddlers and stunting cadres in Nyogan Village. The results of the activity showed a significant increase in students' knowledge with an average increase of 6.31 points. In the training of cadres, it was also found that there was an increase in cadre knowledge, the average knowledge during the pre-test was 15.63 and increased to 16.25 during the post-test. It is also seen that there is an increase in the skills of cadres in anthropometric measurements which is shown through practical activities in measurement simulations. All the participants of the activity looked enthusiastic and showed seriousness in participating until the end of the event. The results of monitoring nutritional status according to the Body Mass Index according to Age (BMI/U) of students who experience malnutrition are still high, reaching 35.8% and 9% being overweight and obese. This activity is expected so that students and families can apply sanitary and healthy living behaviors, both at school and at home, and the school can monitor the nutritional status on a regular basis for toddlers and school-age children both at Posyandu and in screening activities for school children through the program.
