Indonesian Abstract

Tanaman Sawi Pak Choi (Brassica rapa, L.) merupakan sejenis sayuran yang digemari masyarakat dan mempunyai nilai ekonomis serta kaya akan zat essensial (protein, karbohidrat, dan lemak), vitamin dan mineral. Sawi termasuk jenis sayuran daun yang mempunyai nilai ekonomi tinggi di Indonesia maupun beberapa negara di dunia. Pak choi (Brassica rapa L.) memiliki prospek yang bagus untuk dikembangkan di Indonesia karena budidayanya yang mudah serta kandungan gizinya. Pak choi dapat tumbuh sepanjang tahun di dataran rendah. Pak choi merupakan sumber vitamin dan mineral seperti 53 mg vitamin C, 3 mg β-karoten, dan 102 mg Ca dalam 100 g bobot segar (Tay dan Toxofeus, 1994). Foth (1990) menyatakan bahwa, pupuk kandang memiliki pengaruh yang sangat baik terhadap sifat fisik dan kimiawi tanah serta meningkatkan perkembangan aktivitas jasad renik. Pupuk kandang ayam kandungan unsur haranya lebih sempurna dan lebih mudah diserap oleh tumbuhan. Kandungan pupuk kandang ayam lebih tinggi dalam nitrogen dari pupuk kandang kuda dan sapi (Adhitya, 2013). Unsur N sendiri sangat dibutuhkan tanaman sawi, khususnya untuk proses pertumbuhan vegetatif tanaman. Karena tanaman sawi merupakan tanaman yang diambil daunnya, sehingga peranan Nitrogen sangat penting untuk pembentukan daun yang hijau segar dan cukup mengandung serat. Pupuk anorganik yang banyak mengandung unsur Nitrogen dan sering dijumpai antara lain adalah pupuk Urea dan pupuk ZA. Dengan pemberian pupuk anorganik atau pupuk buatan, khususnya pupuk ZA, diharapkan akan mampu menambah kandungan N tanah (Tisdale et al, 1990). Penelitian ini bertujuan untuk mengetahui pengaruh media tanam dan tingkat hara dalam tanah terhadap pertumbuhan serta hasil tanaman sawi Pak Choi varietas Green Fortune. Dengan menggunakan media tanam yang berupa campuran tanah, arang sekam, dan pupuk kandang ayam 1:1:1 serta pemberian 75 kg N/ha ( Urea) dan 75 kg N/ha (ZA) dapat meningkatkan pertumbuhan serta hasil tanaman sawi Pak Choi. Penelitian dilakukan di green house kebun percobaan Sekolah Tinggi Teknik Pertanian ( STTP ) Malang Perumahan Ijen Nirwana, dilaksanakan pada bulan Juli hingga Agustus 2014. Peralatan yang digunakan dalam penelitian ini adalah polybag berukuran 10 kg, gunting, tugal, sekop, tray semai, gembor, label, penggaris, timbangan analitik, oven, Leaf Area Meter, plot nama, dan kamera. Bahan penelitian ini menggunakan tanaman pak choi varietas Green Fortune, tanah, arang sekam. Pupuk yang digunakan ialah pupuk kandang ayam, Urea dan ZA. penelitian ini menggunakan Rancangan Acak Kelompok (RAK) yang terdiri dari, K1 : Tanah, Arang Sekam, Pupuk Kandang Ayam dengan perbandingan 1:1:1 ,serta 150 kg N/ha (Urea), K2 : Tanah, Arang Sekam, Pupuk Kandang Ayam dengan perbandingan 1:1:1 serta 150 kg N/ha (ZA), K3 : Tanah, Arang Sekam, Pupuk Kandang Ayam dengan perbandingan 1:1:1 ,serta 75 kg N/ha (Urea) + 75 kg N/ha (ZA), K4 : Tanah, Arang Sekam, Pupuk Kandang Ayam dengan perbandingan 1:1:1 serta 112,5 kg N/ha (Urea) + 37,5 kg N/ha (ZA), K5 : Tanah, Arang Sekam, Pupuk Kandang Ayam dengan perbandingan 1:2:0 serta150 kg N/ha (Urea), K6 : Tanah, Arang Sekam, Pupuk Kandang Ayam dengan perbandingan 1:2:0 serta150 kg N/ha (ZA), K7 Tanah, Arang Sekam, Pupuk Kandang Ayam dengan perbandingan 1:2:0 serta75 kg N/ha (Urea) dan 75 kg N/ha (ZA), K8 : Tanah, Arang Sekam, Pupuk Kandang Ayam dengan perbandingan 1:2:0 serta112,5 kg N/ha (Urea) + 37,5 kg N/ha (ZA), K9 : Tanah, Arang Sekam, Pupuk Kandang Ayam dengan perbandingan 0:2:1 serta150 kg N/ha (Urea), K10 : Tanah, Arang Sekam, Pupuk Kandang Ayam dengan perbandingan 0:2:1 serta 150 kg N/ha (ZA), K11 : Tanah, Arang Sekam, Pupuk Kandang Ayam dengan perbandingan 0:2:1 serta75 kg N/ha (Urea) + 75 kg N/ha (ZA), K12 : Tanah, Arang Sekam, Pupuk Kandang Ayam dengan perbandingan 0:2:1 serta 112,5 kg N/ha (Urea) + 37,5 kg N/ha (ZA). Pengamatan yang dilakukan adalah non destruktif ( tinggi tanaman, jumlah daun), pengamatan destruktif dilakukan pada umur tanaman 7, 14, 21,28 hst dengan cara mengambil 2 tanaman contoh, parameter yang diamati adalah Luas daun pertanaman, Bobot kering total tanaman, sedangkan pengamatan panen dilakukan setelah 30 hst dengan cara mengambil 6 tanaman contoh yang meliputi Umur panen, Bobot segar total tanaman, Bobot segar konsumsi. Dari hasil penelitian dapat disimpulkan bahwa Pada perlakuan K3 dengan pemberian media tanam campuran tanah, arang sekam, pupuk kandang ayam 1:1:1, perbandingan volume serta pemberian 75 kg N/ha (Urea) + 75 kg N/ha (ZA) dibandingkan dengan perlakuan lainnya yang di coba, menunjukkan rata-rata lebih tinggi, yaitu terhadap tinggi tanaman, luas daun tanaman sawi pak choi, bobot kering, bobot segar, bobot segar total, bobot segar konsumsi, dan diameter bonggol tanaman pak choi menjadi tinggi, dan umur panen tanaman sawi pak choi lebih cepat yaitu 38 hst. Pada perlakuan K9, K10, K11, dan K12 pertumbuhan serta hasil tanaman pak choi rendah dari perlakuan yang lain, hal ini juga dipengaruhi oleh campuran media tanam yaitu tanah, arang sekam, pupuk kandang ayam 0:2:1 perbandingan volume yang menyebabkan unsur hara atau kelebihan unsur hara, meskipun jumlah total penyediaan sama dengan jumlah total kebutuhan dan umur panen jauh lebih lambat yaitu 42 hst.

English Abstract

Plant mustard of Pak Choi ( Brassica rapa, L. var. chinensis ) Is a kind of vegetables popular community and have economic value as well as rich a substance essensial ( a protein , carbohydrates , and fat ), vitamins and minerals. Mustard greens included the types of leaf vegetables that have high economic value in indonesia and the countries in the world .Pak Choi ( brassica rapa l . ) having good prospects to be developed in indonesia Because its cultivation that is easily as well as the content of nutrition . Pak Choi can grow throughout the year in the lowlands . Pak Choi is a source of vitamins and minerals like 53 mg of vitamin c , 3 mg β -karoten , and 102 mg ca in 100 g weights fresh ( tay and toxofeus , 1994 ). Foth ( 1990 ) said that , manure having a very good influence on the nature of the physical and chemical land development and increase the activity of microorganisms .Chicken manure content disturbances his element more perfect and more easily absorbed by plants .Manure content chicken in higher nitrogen from manure horses and cattle ( adhitya , 2013 ). N itself is also very element needed plant mustard greens, especially for the process of growth vegetative plants. Because the plant mustard is taken of its leaves, so that the role of nitrogen very important for the formation of fresh green leaves and fairly containing fibers. Many contain a fertilizer inorganic nitrogen and often it was found among others are ZA Urea fertilizer and fertilizer. By the provision of inorganic fertilizer or chemical fertilizer, especially fertilizer ZA, is expected to be able to enhance the womb n the ground ( Tisdale et al , 1990 ). This research aims to understand the influence of the media cropping and the level of disturbances in the ground on the growth and the results of a plant mustard Pak Choi varieties of green fortune. By using the media of cropping mixture of ground , charcoal chaff , and chicken manure 1: 1: 1 and the provision of 75 kg N / ha ( Urea ) and 75 kg N / ha ( ZA ) can improve growth and the results of a plant mustard Pak Choi. The research was done in the green house gardens high school experiment agricultural techniques ( STTP ) malang ijen nirwana housing , carried out in july until august 2014. Equipment used in this research was polybag measuring 10 kg , scissors, tugal, a spade, oscillating semai, gembor, a label, a ruler, scales analytic, an oven, leaf area meters, a plot the name, and the camera. This research material plant use sir choi varieties green fortune, the ground charcoal husks. A fertilizer that is used is chicken manure, Urea and ZA. This research using random design group ( RAK ) which consists of K1: Planting a mixture of media between Soil, charcoal chaff , and chicken manure by comparison 1: 1: 1 and 150 kg of N / ha ( Urea ), K2: Planting a mixture of media between Soil, charcoal chaff, and chicken manure by comparison 1: 1 :1 and 150 kg N / ha ( ZA ), K3: Planting a mixture of media between Soil, charcoal chaff, and chicken manure by comparison 1: 1 :1 and 75 kg N/ha (Urea) + 75 kg N/ha (ZA), K4: Planting a mixture of media between Soil, charcoal chaff, and chicken manure by comparison 1: 1 :1 and 112,5 kg N/ha (Urea) + 37,5 kg N/ha (ZA), K5: Planting a mixture of media between Soil, charcoal chaff , and chicken manure by comparison 1: 2: 0 and 150 kg of N / ha ( Urea ), K6: Planting a mixture of media between between Soil, charcoal chaff , and chicken manure by comparison 1: 2: 0 and 150 kg of N / ha ( ZA ), K7: Planting a mixture of media between between Soil, charcoal chaff , and chicken manure by comparison 1: 2: 0 and 75 kg N/ha (Urea) + 75 kg N/ha (ZA), K8: Planting a mixture of media between between Soil, charcoal chaff , and chicken manure by comparison 1: 2: 0 and 112,5 kg N/ha (Urea) + 37,5 kg N/ha (ZA), K9: Planting a mixture of media between Soil, charcoal chaff, and chicken manure by comparison 0:2:1 and 150 kg of N / ha ( Urea ), K10: Planting a mixture of media between Soil, charcoal chaff, and chicken manure by comparison 0:2:1 and 150 kg of N /ha ( ZA ), K11: Planting a mixture of media between Soil, charcoal chaff, and chicken manure by comparison 0:2:1 and 75 kg N/ha (Urea) + 75 kg N/ha (ZA), K12: Planting a mixture of media between Soil, charcoal chaff, and chicken manure by comparison 0:2:1 and 112,5 kg N/ha (Urea) + 37,5 kg N/ha (ZA). The observation made is non destructive ( higher plants, number of leaves ), destructive observation done at the age of a plant 7, 14, 21, 28 hst by means of took 2 plant example, parameter that observed is broad leaves plant , dry weight total plants, while observation harvest will be done after 30 hst with way to 6 plant an example which includes harvest age, fresh weight total plants, fresh weight consumption. From the research we can conclude that in treatment k3 by the provision of growing media a mixture of, charcoal husks, chicken manure 1: 1: 1, and provision of 75 kg N / ha ( Urea ) + 75 kg N / ha ( ZA ). Compare with other treatments and the result of higher plants, broad leaves of a plant mustard greens Pak Choi, dry weight , fresh weight, fresh the total weight, fresh weight consumption, and diameter of excrescence sir choi plants to high , and the days of mustard harvest plants sir choi faster which hst 38. With increasing the womb N at K9 treatment, K10, K11, K12 .30 % and as much as 0.16 %, 0.23 %, and 0.33 % hence growth and crop yield sir choi lower than other treatment, it is also influenced by a mixture of growing media the land , charcoal husks, chicken manure 0:2:1 deficiency causing organic element or excess organic element, although the total number of the provision of equal to the sum total need for and the days of the harvest is much slower namely 42 hst.
