Abstract : The health of pregnant women is an important problem to be considered because it impacts the health status of all the people of an area. The importance of this issue is reflected in the United Nations' efforts to address pregnant women’s health: the Sustainable Development Goals (SDGs). Develop an effort model for pregnant women's health through Qanun on the prevention and control of Chronic Energy Deficiency (CED) in pregnant women at the village level to reduce cases of CED and become a reference for other regions. This study uses mathematical modelling to support regional policies with qualitative and quantitative approaches. The application of this mathematical model assesses the success of the Qanun implementation in the prevention and control of CED in pregnant women. The subjects measured were Tuha Peut and pregnant women. Interventions were given to research subjects at the empowerment stage in the form of (1) implementing the Qanun and the Tuha Peut empowerment model, (2) analysing the perception of Tuha Peut, which includes behavioural domains, (3) strengthening the capacity of Tuha Peut to become the agent of change, (4) measuring Tuha Peut's behavioural practices, (5) measuring the acceptability of maternity care services, (6) strengthening coordination with the Health Service Center or Puskesmas, (7) increasing the Tuha Peut’s Capacity in the Qanun implementation, and (8) monitoring the Qanun implementation. The success of Qanun implementation was measured by (1) analysing program operations (indicators of input, process, output, or outcome), (2) measuring Tuha Peut's efforts in shaping positive behaviour of pregnant women regarding local food consumption, (3) measuring changes in eating behaviour in pregnant women, (4) providing supplementary food for pregnant mothers suffering from CED, (5) decreasing the prevalence of CED events, (6) implementing continuous Qanun and other village policies, and (7) evaluating the Qanun implementation. The contribution of Tuha Peut empowerment modelling in maternal health policies, which can be a reference for other regions, was measured by (1) measuring the prevalence of CED in villages that have implemented the Qanun Gampong, (2) measuring the prevalence of stunting in children born to CED pregnant women who have applied the Qanun Gampong during pregnancy, (3) measuring changes in newly pregnant women's behaviour for Qanun sustainability, (4) scaling up for other villages to develop and implement the Qanun, and (5) making Tuha Peut a peer educator for other villages.
