Ainy, Syifaul (2019) Pengaruh Umur Bibit Pada Pertumbuhan dan Hasil Tanaman Kailan (Brassica oleraceae) Sistem Ratun Secara Hidroponik NFT (Nutrient Film Technique). Sarjana thesis, Universitas Brawijaya.
Abstract
Kailan (Brassica oleracea) termasuk kedalam hortikultura jenis kubis-kubisan yang memiliki nilai ekonomi tinggi. Prospek pengembangan dan pemasaran kailan sangat menjanjikan karena kebutuhan masyarakat terhadap kandungan gizi pada sayuran kalian sangat tinggi. Konsumsi kailan di Indonesia mengalami peningkatan dari tahun ke tahun, namun kendala pengembangannya di Indonesia ialah peningkatan permintaan kailan didalam negeri tidak diikuti dengan peningkatan produksinya. Apalagi dengan semakin menurunnya luasan lahan yang tersedia untuk budidaya pertanian yang menjadi kendala pada budidaya kailan secara konvensional. NFT (Nutrient Film Technique) dapat menjadi suatu solusi untuk memecahkan masalah tersebut. Menanam kailan menggunakan sistem hidroponik NFT umumnya dilakukan persemaian terlebih dahulu sebelum di pindah kedalam modul (media tanam hidroponik). Biasanya para pengusaha hidroponik seringkali kurang memperhatikan umur bibit sehingga terjadi keterlambatan pemindahan bibit ke modul tanam. Pemilihan umur bibit dapat mempengaruhi kondisi tanaman pada saat dipindahkan ke modul tanam. jika pindah tanam terlambat dilakukan, maka tanaman tidak mempunyai cukup waktu untuk menyelesaikan pertumbuhan vegetatifnya, tanaman lebih cepat menua dan cepat memasuki stadia generatif. Selain itu, upaya peningkatan produksi pada tanaman kailan juga dapat dilakukan dengan penerapan panen sistem ratun (panen dilakukan berulangkali). Penelitian ini bertujuan untuk mempelajari pengaruh umur bibit pada pertumbuhan dan hasil tanaman kailan secara NFT pada penerapan panen sistem ratun. Kemudian, untuk mendapatkan informasi mengenai umur bibit yang optimum berdasarkan pertumbuhan dan hasil tanaman kailan. Hipotesis dari penelitian ini diduga Pertumbuhan dan hasil tanaman kailan paling optimal yakni pada perlakuan umur bibit 25 hari setelah semai. Semakin lama umur bibit dapat menurunkan pertumbuhan dan hasil tanaman kailan. Penelitian dilaksanakan di kebun sayur Surabaya yang terletak di di Jln. Gayung Kebonsari gang XI/15, Jambangan, Surabaya. Rancangan percobaan yang digunakan adalah Rancangan Acak Kelompok (Randomized Block Design) dengan satu faktor yaitu umur bibit dengan enam taraf perlakuan yaitu : B1 = Bibit umur 10 hss, B2 = Bibit umur 15 hss, B3 = Bibit umur 20 hss, B4 = Bibit umur 25 hss, B5 = Bibit umur 30 hss, B6 = Bibit umur 35 hss. Setiap perlakuan diulang sebanyak 4 kali sehingga diperoleh 24 satuan percobaan. Pengamatan dilakukan dengan mengamati tanaman kailan secara non dekstruktif dengan mengambil 3 tanaman contoh untuk setiap perlakuan yang didapatkan pada saat tanaman berumur 7 hst, 14 hst, 21 hst, 28 hst, 35 hst dst. hingga mencapai panen yang kedua. Pengamatan meliputi Komponen pertumbuhan antara lain, tinggi tanaman, jumlah daun, luas daun, umur saat panen pertama, umur saat panen kedua. Sedangkan komponen hasil meliputi bobot segar total tanaman, bobot segar konsumsi tanaman, uji kualitas iv kekerasan batang, kadar air serta indeks panen. Analisa data menggunakan analisis ragam (ANOVA), apabila terdapat pengaruh nyata dilanjutkan dengan uji Bda Nyata Terkecil (BNT) pada taraf 5%. Perlakuan umur bibit berpengaruh nyata terhadap pertumbuhan tinggi tanaman, jumlah daun dan luas daun. Perlakuan umur bibit berpengaruh nyata terhadap bobot segar total tanaman, bobot segar konsumsi tanaman, uji kualitas kekerasan batang, kadar air serta indeks panen. Pertumbuhan vegetatif tanaman kailan serta indeks panen paling baik terdapat pada perlakuan umur bibit 25 HSS. Komponen hasil tanaman kailan antara lain bobot segar total panen, total bobot segar konsumsi, kekerasan batang dan kadar air paling baik terdapat pada perlakuan umur bibit 10 HSS.
English Abstract
Kailan (Brassica oleracea) included into horticulture type of cabbage that have high economic value. Prospects for the development and marketing of kailan very promising because of the social demand for the nutrients in the vegetables you are very high. Kailan consumption in Indonesia has increased from year to year, but the constraints of development in Indonesia is the increasing demand for domestic kailan not followed by an increase in production. Moreover, with the decrease of land area available for cultivation is a constraint on the cultivation of conventional crocheted. NFT (Nutrient Film Technique) can be a solution to solve the problem. Planting Kailan using NFT hydroponics system is generally performed in the nursery before moving into the module (hydroponic growing media). Usually employers are often less attention hydroponic seedlings so that there is delay in transfer of seedlings to planting module. Selection seedling age can affect the condition of the plant at the time of planting was transferred to the module. if transplanting late done, the plants do not have enough time to complete the vegetative growth, faster aging plants and quickly entered the generative stage. In addition, efforts to increase production at the plant kailan can also be done with the application of the system ratoon harvest (the harvest is done repeatedly). The purpose of this research is studied the effect of seedling age on the growth and yield in NFT kailan at harvest application ratun system. Then, to obtain information about the optimum seedling age is based on the growth and yield. The hypothesis of this research is the growth and yield of kailan will be optimal at seedlings age treated 25 days after seedling. The longer the age of the seedlings can reduce the growth and yield of kailan plants. The research was conducted at the Surabaya vegetable garden located at Jln. Gayung Kebonsari gang XI / 15, Jambangan, Surabaya. The experimental design used was Randomized Block Design with one factor, namely the age of the seedlings with six levels of treatment, namely: B1 = Seeds aged 10 hss, B2 = Seeds aged 15 hss, B3 = Seeds aged 20 hss, B4 = Seed age 25 hss, B5 = Seed age 30 hss, B6 = Seed age 35 hss. Each treatment was repeated 4 times to obtain 24 experimental units. Observations were carried out by observing the kailan plants in a non-destructive manner by taking 3 sample plants for each treatment obtained when the plants were 7 days old, 14 days, 21 days, 28 days ago, 35 days ago. until it reaches the second harvest. Components of growth include, plant height, number of leaves, leaf area, age at first harvest, age at second harvest. While the yield components include the total fresh weight of the plant, the fresh weight of plant consumption, test the quality of stem hardness, moisture content and harvest index. Data analysis using variance analysis (ANOVA), if there is a real effect followed by the Less Signicantly Different (LSD) at the level of 5%. Seedling age significantly affected the growth of plant height, number of leaves and leaf area. Seedling age significantly affected the total fresh weight of plants, fresh weight of plant consumption, quality test of stem hardness, water vi content and harvest index. Vegetative growth of kailan plants and harvest index are best found in the treatment of 25 DAS. The components of the kailan plant include fresh weight of total harvest, total fresh weight of consumption, stem hardness and the best water content found in the treatment of 10 DAS.
