ABSTRACT Stunting is a major threat to the quality of Indonesian people, as well as a threat to the nation's competitiveness. This is because being stunted, not only disrupts physical growth (short stature/stunt), but also disrupts brain development. The aim of this research is to determine the relationship between LBW and exclusive breastfeeding with the incidence of stunting. The type of research used is a descriptive analytical survey with a cross sectional design. The population in this study was all mothers with toddlers who were weighed at the Johan Pahlawan Health Center, Meulaboh City, West Aceh Regency, totaling 50 people. The subject sampling technique used a total sampling of 50 people. The type of data used in this research is primary data. The instruments used in this research were observation sheets and questionnaires to measure birth weight and the incidence of stunting. The variable for exclusive breastfeeding was collected using a questionnaire. Research data analysis was univariate and bivariate analysis using the chi square test. The results of the study explained that there was a relationship between LBW and the incidence of stunting (P = 0.004) and there was a relationship between exclusive breastfeeding and the incidence of stunting (P = 0.008). Based on the incidence of LBW, the majority of respondents were in the not LBW category as many as 32 people (63%) and minority respondents were in the LBW category as many as 18 people (36%).
