Pemberian ASI eksklusif pada bayi telah dianjurkan oleh semua pihak. ASI tidak hanya dapat memenuhi kebutuhan energi bayi, tetapi juga memberikan makronutrien dan mikronutrien yang penting untuk tumbuh kembang bayi. Walaupun demikian, cakupan pemberian ASI eksklusif belum dapat dikatakan optimal. Hal tersebut dipengaruhi oleh kurangnya pengetahuan ibu mengenai kandungan nutrisi ASI dan faktor ibu yang bekerja. Pengabdian masyarakat ini bertujuan untuk memberikan edukasi kepada ibu menyusui mengenai kandungan ASI dan pemberian ASI perah (ASIP). Kegiatan dilakukan secara online melalui Zoom. Kegiatan berupa seminar atau penyuluhan dengan menghadirkan 3 topik dan 3 narasumber. Evaluasi keberhasilan kegiatan dilakukan dengan menilai suasana diskusi dan memberikan pertanyaan tertutup melalui pra dan pascates. Sebanyak 29 ibu menyusui mengikuti kegiatan ini dengan rerata usia 29 tahun dan sebagian besar bekerja (80%). Para peserta antusias memberikan pertanyaan kepada para narasumber. Hasil evaluasi pra dan pascates menunjukkan ada peningkatan pengetahuan ibu menyusui sebesar 31% (p=0,000). Kegiatan pengabdian masyarakat berupa edukasi kandungan ASI dan pemberian ASIP berhasil dilakukan dengan baik. Edukasi mampu meningkatkan pengetahuan ibu menyusui. Edukasi atau penyuluhan dapat dilakukan untuk meningkatkan pengetahuan atau pemahaman masyarakat.Abstrak ditulis dalam bahasa Indonesia dan Inggris.

It fulfills the baby's energy needs and provides nutrients that are necessary for baby's growth and development. However, the coverage of exclusive breastfeeding has not yet been sufficient, that is affected by the mother’s lack of knowledge about breast milk and the mother’s occupation.

Breast milk is the best source of nutrition for newborns.  Breast milk content is composed of water, protein, carbohydrates, fats, vitamins, minerals, antibodies, and enzymes. Breast milk also contains white blood cells and substances that make up the baby`s immune system such as immunoglobulins and lysozyme. The composition of breast milk can change depending on the needs and ages of the baby. Exclusive breastfeeding is recommended by many doctors and other healthcare professionals. One of the factors that influence exclusive breastfeeding is the mother`s knowledge about the content of breast milk. Most breastfeeding mothers do not know the nutritional content of breast milk, both macronutrients, and micronutrients. Breast milk is also rich in immune cells, antibodies, and other bioactive ingredients that help protect the baby from infection until the baby has an effective antibody response in the first few months of life. Breast milk is an ideal nutrient for babies. The mixture of vitamins, proteins, and fats in breast milk can provide the nutrients and calories the baby needs to grow. Babies who have been breastfed for 6 months are more likely to reach their ideal weight.Therefore, the government recommends exclusive breastfeeding for infants up to the age of 6 months.
