ABSTRACT High-risk pregnancies could affect the condition of the mother and fetus and could lead to pathological labor processes. The health condition of pregnant women played an important role in preventing pregnancy complications. The government's strategy to prevent the risk of pregnancy complications was through a family-based approach using the MCH Book from the pregnancy period. In 2021, the MMR was 4/100,000 live births. The coverage of Pregnancy Visits (K6) in Popoh village had not reached the target of 100%, achieving only 33.33%. The target for pregnancy complications was 15-20%, but 38.89% was achieved, and the handling of obstetric complications reached 57.14% of the target of 100%. Meanwhile, the detection of high-risk pregnancies by the community reached 5.56% of the target of 20%. The goal of this activity was to increase community knowledge and awareness through the empowerment of cadres and families based on the MCH book as an effort to prevent pregnancy complications in Popoh village, Wonoayu District, Sidoarjo. The counseling was conducted over three days and was attended by 23 cadres and 18 families of pregnant women with lectures, Question and Answer sessions, pre-tests, and post-tests. The results of the activity included an improvement in the quality of cadres, marked by an increase in knowledge with an average post-test score of 92%, skills with an average score of 83.53%, and the formation of a joint commitment to support the use of the MCH book as an effort to prevent pregnancy complications. The outcomes were an increase in understanding and skills of the cadres and families, intellectual property rights, modules, and journals.
