Penelitian ini bertujuan untuk: 1) menentukan dosis pupuk petroganik yang paling efektif bagi pertumbuhan dan hasil tanaman kubis bunga, 2) menentukan konsentrasi pupuk organik cair NASA yang paling efektif bagi pertumbuhan dan hasil tanaman kubis bunga, 3) menentukan kombinasi perlakuan dosis pupuk petroganik dan konsentrasi pupuk organik cair NASA yang paling efektif bagi pertumbuhan dan hasil tanaman kubis bunga. Penelitian ini dilaksanakan di lahan pasir pantai Desa Banjarsari, Kecamatan Nusawungu, Kabupaten Cilacap pada bulan Oktober sampai Desember 2018. Rancangan penelitian yang digunakan yaitu Rancangan Acak Kelompok Lengkap (RAKL) dengan 2 faktor dan 3 ulangan. Faktor pertama yaitu dosis pupuk petroganik yang terdiri dari 3 taraf yaitu 0 t/ha, 30 t/ha dan 60 t/ha. Faktor kedua yaitu konsentrasi pemberian pupuk organik cair yang terdiri dari 3 taraf yaitu 0 ml liter-1, 5 ml liter-1 dan 10 ml liter-1. Variabel yang diamati meliputi tinggi tanaman, jumlah daun, panjang akar, luas daun, kadar kehijauan daun, bobot akar segar, bobot akar kering, bobot daun segar, bobot daun kering, bobot tanaman segar, bobot tanaman kering, bobot batang segar, bobot batang kering, bobot bunga segar, bobot bunga kering, diameter bunga, umur pembungaan bunga dan hasil bunga segar. Data yang diperoleh dianalisis menggunakan uji F dan dianalisis lanjut dengan Duncan’s Multiple Range Test dengan taraf kesalahan 5%. Hasil penelitian menunjukkan bahwa dosis pupuk petroganik 47,67 t/ha mampu meningkatkan pertumbuhan dibanding kontrol pada panjang akar 2,02 cm atau 12,7 %, dosis pupuk petroganik 60 t/ha mampu meningkatkan hasil dibanding kontrol pada bobot bunga segar 85,16 g/tanaman atau 133%, diameter bunga 3,37 cm atau 47,5%, mempercepat umur pembungaan 4,67 hari/tanaman atau 12,93 % dan hasil bunga segar tertinggi 3,44 t/ha atau 133%. Pemberian konsentrasi pupuk organik cair Nasa 0 ml liter-1, 5 ml liter-1 dan 10 ml liter-
1 belum mampu meningkatkan pertumbuhan dan hasil kubis bunga. Kombinasi perlakuan dosis pupuk petroganik 60 ton/ha dan konsentrasi POC 2,91 ml/L menghasilkan diameter bunga dan kombinasi perlakuan dosis pupuk petroganik 60 t/ha dan konsentrasi 3,86 ml/L menghasilkan bobot bunga kering.

Kata kunci: kubis bunga, lahan pasir pantai, dosis, konsentrasi.

ABSTRACT
This research aimed to: 1) determine the most effective dose of petroganic fertilizer for growth and yield of cauliflower, 2) determine the concentration of NASA's most liquid organic fertilizer for growth and yield of cauliflowers, 3) determine the combination of petroganic fertilizer dosage treatment and the concentration of NASA's liquid organic fertilizer is most effective for the growth and yield of cauliflower. This research was carried out in the coastal sandy land of Banjarsari Village, Nusawungu District, Cilacap Regency in October to December 2018. The research design used was a Complete Randomized Block Design (RCBD) with 2 factors and 3 replications. The first factor is the dose of petroganic fertilizer which consists of 3 levels, namely 0 t / ha, 30 t / ha and 60 t / ha. The second factor is the concentration of liquid organic fertilizer which consists of 3 levels, namely 0 ml liter-1, 5 ml liter-1 and 10 ml liter-1. Variables observed included plant height, leaf number, root length, leaf area, leaf greenery, fresh root weight, dry root weight, fresh leaf weight, dry leaf weight, fresh plant weight, dry plant weight, fresh stem weight, stem weight dry, weight of fresh flowers, weight of dried flowers, diameter of flowers, flowering age and yield of fresh flowers. The data obtained were analyzed using the F test and further analyzed with Duncan's Multiple Range Test with a 5% error rate. The results showed that the dose of petroganic fertilizer 47.67 t / ha was able to increase growth compared to control at 2.02 cm root length or 12.7%, petroganic fertilizer 60 t / ha doses were able to increase yield compared to control at fresh flower weights 85.16 g / plant or 133%, flower diameter 3.37  cm or 47.5%, accelerating flowering age 4.67 days / plant or 12.93% and the highest fresh interest yield 3.44 t / ha or 133%. Giving the concentration of liquid organic fertilizer in the range of 0 ml liter-1, 5 ml liter-1 and 10 ml liter-1 has not been able to increase the growth and yield of flower cabbage. The combination of the treatment of petroganic fertilizer dosage of 60 tons / ha and POC concentration of 2.91 ml / L produced a flower diameter and a combination of the treatment of petroganic fertilizer dose 60 t / ha and a concentration of
3.86 ml / L produced dry flower weight.

Keywords: cauliflower, coastal sandy land, dosage, concentration.
