The groups most vulnerable to malnutrition are pregnant women, infants and toddlers. Nutritional problems on pregnant women, if not addressed immediately will cause mothers to experience Chronic Energy Deficiency (CEC), a solution to overcome the problem of malnutrition of pregnant women are a form of assistance of local food consumption (serwit), by the implementations of Interprofessional Educative- Collaborative Practices (IPE-CP) The aim of the research is to understand the effect of assistance interventions for local food consumption (serwit) with the application of Interprofessional Education- Collaborative Practice (IPE-CP) to the nutritional status of pregnant women. This research is a quantitative research, a type of quasi-experiment research, Pre-post test group design. Sample of 60 pregnant women in the third trimester, which is divided into 30 intervention groups and 30 control groups. Univariate data analysis uses the Mean formula, bivariate analysis uses the Independent Test T test, and the experiment of the influence of hypothesis uses the Cohen's Effec Size test. Results of the assistance intervention in the consumption of local food consumption (serwit) with the application of Interprofessional Education-Collaborative Practices (IPE-CP) on the nutritional status of pregnant women: Maternal weight with a p-value of 0.003, LiLA size of pregnant women with a p-value of 0,000 and blood Hb levels of maternal with a p-value of 0.025. Effec Test which is the most important measure is maternal height with an effect size index: 0.79 standard big categories. The advice should be an existence of need to always apply IPE-CP and to continue to preserve local food consumption (serwit) to improve the nutritional status of pregnant women
