Besar sampel pada penelitian sebanyak 30 responden ibu nifas yang ada di ruang Nifas RSUD dr. Doris Sylvanus Kota Palangka Raya. Pengambilan sampel menggunakan teknik purposive sampling dan pengujian statistik menggunakan uji statistik Chi-Square.Hasil: Berdasarkan hasil penelitian pada variabel perawatan payudara diperoleh nilai p = 0,048 (P Value a 0, 05) sehingga dapat disimpulkan bahwa ada hubungan perawatan payudara dengan produksi ASI dan pada variabel frekuensi pemberian ASI diperoleh nilai p = 0,009 (P Value a 0,05).Kesimpulan: ada hubungan perawatan payudara dan frekuensi pemberian ASI terhadap produksi ASI sehingga tindakan perawatan payudara yang baik dan secara rutin serta pemberian ASI sesering mungkin dapat membantu meningkatkan produksi ASI. Kata Kunci: Perawatan, Frekuensi, Menyusui dan Produksi ASIBackground: Breast milk can meet the nutritional needs of infants, immunology and psychological.
