UJI KADAR PROTEIN AIR SUSU IBU (ASI) DAN SUSU FORMULA PADA BAYI USIA 6-12 BULAN

At the beginning of its growth, humans obtain protein to grow and develop from breast milk (ASI). Breast milk is the best nutrition for babies. Breast milk contains all the nutrients a baby needs to meet his nutritional needs during the golden period and its contents are adapted to the conditions of each baby. There are still many mothers in Indonesia who give formula milk to their children so that the amount of exclusive breastfeeding in Indonesia is still relatively low. This research was conducted to test breast milk levels of infants aged 6-12 months and infant brands of formula X aged 6-12 months which are widely circulating in the market. This study uses the kjehdahl method, determination of protein content by the kjeldahl method is an indirect method, namely through the determination of N levels in the material. There are 2 samples used in this study, they are breastfeeding samples of 9 month old babies and samples of infant formula milk X 6-12 months. Each sample was duplicated to improve the accuracy of the experiment. The results showed that the average protein content of brand formula milk was 8.76 while the content of breast milk protein for 9-month-old infants was 3.48. Protein content in infant formula milk brand X 6-12 months is higher than protein content in breast milk at the age of 9 months. Keywords: Protein, ASI, Susu Formula, Metode Kjehdahl
