Results : There is an influence of internal factors, namely the nutritional knowledge variable with (P value = 0.04), external factors, namely the food texture variable with (P Value = 0.02), food taste with (P value = 0.02), food taste with (P value = 0.04). P Value = 0.05), food variety with (P Value = 0.04) and food aroma with (P Value = 0.04). Meanwhile, the factors that have no influence are internal factors, namely education with (P Value = 0.09) and eating habits with (P Value = 0.76). Conclusion : There is an influence of internal and external factors on the acceptance of pregnant women through food waste during supplementary feeding.
