ASI memiliki manfaat nutrisional dan non nutrisional baik untuk kesehatan anak dan Ibu. WHO merekomendasikan ASI eksklusif sampai usia 6 bulan  dilanjutkan sampai 2 tahun. Data WHO menyatakan pemberian ASI eksklusif di ASI tenggara seperti Myanmar mencapai 23,6%, Kamboja 65,2% Indonesia 41,5% jumlah penurunan pemberian ASI eksklusif tidak hanya terjadi di negara maju namun juga terjadi di negara berkembang seperti di Indonesia. <em>Breastfeeding Self-Efficacy</em> merupakan faktor yang paling kuat yang dapat mempengaruhi proses menyusui dan keberhasilan pemberian ASI eksklusif.</p><p><strong>Tujuan: </strong>Mengetahui Faktor yang mempengaruhi <em>Breasfeending  Self Efficacy</em> (BSE) dalam Pemberian Asi Eksklusif Pada Ibu Hamil Trimester 3.</p><p><strong>Metode:</strong> Penelitian ini merupakan penelitian deskriptif analitik non eksperimental, rancangan <em>cross sectional.</em> Jumlah responden sebanyak 58 responden dengan teknik <em>accidental sampling</em>.

ASI has nutritional and non-nutritional benefits both for the health of children and mothers. WHO recommends exclusive breastfeeding until the age of 6 months is continued for up to 2 years. WHO data states that exclusive breastfeeding in southeast ASI such as Myanmar reaches 23.6%, Cambodia 65.2% Indonesia 41.5%, the decrease in exclusive breastfeeding does not only occur in developed countries but also occurs in developing countries such as Indonesia. Breastfeeding Self-Efficacy is the most powerful factor that can affect the breastfeeding process and the success of exclusive breastfeeding.<br /> <strong>Objective:</strong> To find out the factors that influence Breasfeending Self Efficacy (BSE) in giving exclusive breastfeeding to trimester 3 pregnant women.</em></p><p><strong><em>Method:</em></strong><em> This study is a non-experimental analytic descriptive study, cross sectional design. The number of respondents is 58 respondents with accidental sampling technique. The instrument in this study used a questionnaire.

This lesson provides evidence that the factors that affect Self-efficacy breeding (BSE) are the need for motivation from the mother, husband's support and support from health workers. Breasfeeding Self Efficacy (BSE) is the most influential factor in the breastfeeding process and the achievement of the success of exclusive breastfeeding in the future.</em></p>
