Abstract

Abstrak. Pertumbuhan balita merupakan suatu proses pertambahan ukuran, baik volume,
bobot dan jumlah sel yang bersifat irreversible. Pertumbuhan dan perkembangan
balita suatu hal yang perlu mendapat perhatian besar, biasanya dikenal dengan istilah
golden age. Oleh karena itu, pertumbuhan balita harus dilakukan pemantauan dengan
mengukur berat badan setiap bulannya. Pemantauan pertumbuhan balita biasanya
mengacu pada suatu kurva pertumbuhan. Untuk merancang kurva pertumbuhan balita
di Kota Padang yaitu dengan pendekatan spline kuadratik. Pemilihan model terbaik
yaitu dengan cara pemilihan banyak serta nilai titik knot berdasarkan nilai GCV yang
minimum. Dari analisis regresi spline kuadratik diketahui bahwa perubahan pola pertumbuhan
balita di Kota Padang terjadi pada umur 3 bulan, 10 bulan dan 15 bulan
pertama. Sehingga diperoleh model regresi spline kuadratik dengan model dugaan:
by i = 3; 251 + 1; 724x + 0; 0382(xi
