Bahzar, MuhammadHafizh (2017) Pengaruh Nutrisi Dan Media Tanam Terhadap Pertumbuhan Dan Hasil Tanaman Pakcoy (Brassica Rapa L. Var. Chinensis) Dengan Sistem Hidroponik Sumbu. Sarjana thesis, Universitas Brawijaya.
Abstract
Produksi pakcoy (Brassica rapa L. var. chinensis) di Indonesia dari tahun 2008 - 2011 mengalami fluktuasi yang dapat dilihat secara berturut – turut : 565,636 ton, 562,838 ton, 583,770 ton dan 580,969 ton. Salah satu upaya untuk meningkatkan produktivitas sawi pakcoy dapat dilakukan dengan teknik budidaya secara hidroponik yang dapat dilakukan pada lahan terbatas. Selain itu, pemberian larutan nutrisi yang tepat dan penggunaan beberapa media tanam akan meningkatkan produktivitas pakcoy. Tujuan dari penelitian ini adalah, untuk Untuk mempelajari interaksi antara larutan nutrisi dan media tanam, dan pengaruh masing-masing perlakuan terhadap pertumbuhan dan hasil tanaman pakcoy. Hipotesis yang diajukan yaitu, terdapat interaksi antara larutan nutrisi dan media tanam terhadap pertumbuhan dan hasil tanaman pakcoy. Selain itu, semakin baik kualitas larutan nutrisi daya serap media tanam terhadap nutrisi akan meningkatkan pertumbuhan dan hasil tanaman pakcoy. Penelitian dilaksanakan di kebun hidroponik milik P.T. Agro Dua Satu Gemilang yang beralamat di Jl. Raya Sawunggaling No. 177 Jemundo, Kecamatan Taman, Kabupaten Sidoarjo, pada bulan Juni sampai dengan September 2016. Penelitian ini adalah percobaan faktorial yang menggunakan RAK (Rancangan Acak Kelompok) yang terdiri dari dua faktor, nutrisi (N) dengan N1 : 3 L AB mix; N2 : 2 L AB mix + 1 L Biourin; N3 : 1 L AB mix + 2 L Biourin; N4 : 3 L Biourin; dan media tanam (M) dengan M1 : Rockwool; M2 : Cocopeat; M3 : Arang Sekam; sehingga mendapatkan 12 kombinasi perlakuan yang diulang sebanyak 3 kali, pada setiap plot terdiri dari 9 tanaman. Pengamatan pertumbuhan diamati setiap minggu (7, 14, 21, 28, 35, 42 HST) dengan parameter tinggi tanaman, jumlah daun dan diameter batang. Selanjutnya, pengamatan panen diamati pada 49 HST dengan parameter luas daun per-tanaman, panjang akar, bobot segar total, bobot segar akar, bobot segar konsumsi, bobot kering total. Selain itu, terdapat parameter penunjang berupa pengamatan keasaman air (pH), dan kepekatan nutrisi (EC). Data yang diperoleh, diolah dengan menggunakan uji F pada taraf 5 %. Hasil data yang menunjukkan pengaruh nyata, dapat dilanjutkan dengan uji BNJ pada taraf 5%. Berdasarkan hasil analisis data tentang pengaruh larutan nutrisi komposisi media tanam terhadap pertumbuhan dan hasil pakcoy (Brassica rapa L. var. chinensis) pada sistem hidroponik sumbu dapat disimpulkan bahwa terdapat interaksi antara larutan nutrisi dan komposisi media tanam terhadap luas daun dan bobot segar total tanaman pakcoy. Perlakuan N1M1, N1M2, N1M3, N2M1, N2M2, N2M3, N3M1, N3M2, dan N3M3 menunjukkan uas daun dan bobot segar total yang lebih tinggi dibandingkan N4M3. Larutan nutrisi berpengaruh nyata terhadap tinggi tanaman dan berat kering total. Perlakuan N1 dan N2 menunjukkan tinggi tanaman dan berat kering total yang lebih tinggi dibandingkan N3 dan N4. Penggunaan media tanam berpengaruh nyata terhadap tinggi tanaman. Perlakuan M1 dan M3 menunjukkan tinggi tanaman yang lebih tinggi dibandingkan M2.
English Abstract
Production of pakcoy (Brassica rapa L. var. chinensis) in Indonesia from 2008-2011 was fluctuated, it can be viewed in sequence: 565.636 tons, 562.838 tons, 583.770 tons and 580.969 tons. One effort to increase productivity of pakcoy can be solve with hydroponic cultivation techniques. Through hydroponic cultivation techniques, agricultural land availability problems of diminishing returns can be overcome. Other efforts to improve productivity of pakcoy be achieved by administering nutrient solution and use some of the planting media. The purpose of this research to study the interaction between nutrient and growing media, and the effect of each treatment on the growth and yield of pakcoy. The hypothesis is, there is an interaction between a nutrient solution and planting media on growth and yield of plants pakcoy. Moreover, the better quality of nutrient and the growing media absorption will increase the growth and yield of pakcoy. Research have conducted in hydroponic gardens of P.T. Agro Dua Satu Gemilang which located at Sawunggaling Street No. 177 Jemundo, District Taman, Sidoarjo regency, in June to September 2016. This research is factorial experiment that used RBD (randomized block design) which consists of two factors, nutrients (N) with N1: 3 L AB mix; N2: 2 L AB mix + 1 L Biourine; N3: 1 L AB mix + 2 L Biourine; N4: 3 L Biourine; and planting media (M) with M1: Rockwool; M2: Cocopeat; M3: Charcoal Husk; so getting 12 combination treatment was repeated 3 times, on each plot consists of 9 plants. The observation of growth observed every week (7, 14, 21, 28, 35, 42 DAP) with the parameters plant height, leaf number and stem diameter. Furthermore, the observation of the yield were observed in 49 DAP with the parameters leaf area, root length, fresh weight, fresh weight of roots, fresh weight of consumption, total dry weight. Then, there are supporting parameters exist of water acidity observations (pH), and the concentration observations (EC). Data obtained, processed using the F test at 5% level. Results of data that shows the real effect, continued with HSD test at 5% level. Based on the data analysis from the effect of nutrient solution and growing media on growth and yield of pakcoy (Brassica rapa L. var. chinensis) in the wick hydroponic system can be concluded that there is an interaction between a nutrient solution and growing media composition on the leaf area and total fresh weight of pakcoy. N1M1, N1M2, N1M3, N2M1, N2M2, N2M3, N3M1, N3M2, and N3M3 showed the higher leaf area and total fresh weight than N4M3. Nutrient solution give the real effect on plant height and total dry weight. N1 and N2 showed higher on plant height and total dry weight than N3 and N4 on both parameters. Use of the planting medium give the real effect on plant height. Treatment M1 and M3 showed higher on plant height than M2.
