Rendahnya cakupan pemberian ASI eksklusif menjadi ancaman serius meningkatnya angka kesakitan dan kematian pada bayi. Persepsi kurang cukup suplai ASI menjadi salah satu penyebab kegagalan pemberian ASI eksklusif. Status gizi ibu terutama selama hamil merupakan salah satu faktor penyebab ibu memiliki persepsi tersebut karena ibu dengan status gizi kurang akan mempengaruhi kemampuan ibu untuk mensintesisi air susu yang menyebabkan bayi tidak cukup ASI untuk pertumbuhan dan perkembangannya. Penelitian ini bertujuan untuk melihat hubungan status gizi ibu selama hamil dengan Persepsi Kemampuan Laktasi (PKL) setelah dikontrol oleh variabel umur, kenaikan berat badan selama hamil, pekerjaan, bimbingan laktasi prenatal, paritas, IMD, berat bayi lahir dan penggunaan kontrasepsi. Desain yang dipakai adalah Crossectional terhadap 87 ibu yang memiliki bayi umur >6-12 bulan diwilayah Kabupaten Karawang tahun 2010. Analisis data yang digunakan adalah uji chi square, Uji T independen dan regresi logistik. Hasil penelitian menunjukkan bahwa 58,6% ibu memiliki PKL mampu laktasi. Hasil analisis bivariat yang terbukti berhubungan secara bermakna adalah status gizi selama hamil (0,009), kenaikan berat badan selama hamil (0,002), pekerjaan (0,034) dan berat bayi lahir (0,030). Hasil analisis multivariat menjelaskan bahwa status gizi selama hamil yang sesuai rekomendasi berpeluang 2,176 kali untuk memiliki PKL mampu laktasi dibanding dengan status gizi yang tidak sesuai rekomendasi setelah dikontrol oleh variabel kontrasepsi, umur, paritas, IMD, kenaikan berat badan selama hamil dan berat bayi lahir. Disarankan untuk bidan/nakes agar memberikan konseling menyusui, mencatat dan memantau status gizi ibu, melatih ibu untuk menilai kondisi bayi yang cukup/tidak cukup ASI, mengajarkan cara penyediaan dan penyimpanan ASI bagi ibu yang bekerja. Bagi Dinas kesehatan mengadakan pelatihan konseling dan penilaian serta pengukuran status gizi, pemberian reward dan mengkaji ulang kebijakan pemberian ASI eksklusif sampai 6 bulan untuk ibu-ibu dengan status gizi kurang.
