KATA PENGANTAR

Assalamu’alaikum Warrahmatullahi Wabarakatuh

Syukur Alhamdulillah penulis panjatkan kehadirat Allah SWT, atas limpahan

rahmat dan karunia-Nya, sehingga skripsi dengan judul “Optimalisasi Interval Sirkulasi

Nutrisi Secara Otomasi Pada Hidroponik Sistem Dft (Deep Flow Technique) Terhadap

Pertumbuhan Tanaman Kailan (Brassica oleracea L.)” dapat terselesaikan .

Laporan penelitian ini merupakan salah satu persyaratan untuk menyelesaikan

pendidikan tingkat Sarjana pada Jurusan Agronomi,Fakultas Pertanian Universitas

Muhammadiyah Malang. Dalam proses penyusunan skripsi ini, tidak terlepas dari

bimbingan, dukungan dan bantuan dari berbagai pihak.
