Abstract

Periurban agriculture actually means agriculture that is found surrounding urban boundary. Due to heavy load for various non-agricultural activity and transportation, it necessary to pay attention on the agro-ecological conditions where each crop could grows well. The quality of environment for growing plantsin periurban influences on composition of biochemistry in plants’ tissue. The purpose of this study is to determine the chlorophyll, carotenoid, and ascorbic acid contents in three species of vegetables, those are bayam (Amaranthus tricolor, L.), kangkung (Ipomoea reptans) and sawi (Brassica juncea L.) which were cultivated in three periurban agriculture areas of Surabaya. Total contents of chlorophyll and carotenoid was measured by spectrophotometer. Vitamin C contents was analyzed by DCPIP dye method. The results showed that bayam which was cultivated in Bangkingan-Lakarsantri has the highest content of chlorophyll (3.046 mg/g ) and carotenoid (375.33 μmol/L). The highest content (4.55 μg/g) of vitamin C was found on sawi which was cultivated in Wonorejo. There was no significant difference on chlorophyll content, carotenoid content and vitamin C content between organic vegetables labeled and those are cultivated on Bangkingan-Lakarsantri periurban area. Kawasan pertanian periurban merupakan daerah pertanian yang dijumpai di sekitar pinggiran perkotaan. Berkaitan dengan tekanan lingkungan yang berat di kawasan periurban, akibat berbagai kegiatan non pertanian dan transportasi, perlu adanya perhatian terhadap kondisi agro klimat yang mempengaruhi pertumbuhan tanaman. Kualitas lingkungan tempat tumbuh tanaman pada kawasan pertanian periurban berpengaruh terhadap komposisi kandungan biokimia jaringan tanaman. Tujuan penelitian ini adalah untuk menetapkan kadar klorofil, karotenoid, dan vitamin C pada sayuran bayam (Amaranthus tricolor, L.), kangkung (Ipomoea reptans) dan sawi (Brassica juncea L.) yang dibudidayakan di tiga kawasan periurban Kota Surabaya. Kadar klorofil dan karotenoid diukur dengan spectrophotometer, sedangkan kandungan vitamin C ditetapkan dengan metode titrasi DCPIP. Hasil penelitian menunjukkan bahwa sayuran bayam yang dibudidayakan di kawasan Bangkingan-Lakarsantri memiliki kadar klorofil (3.046 mg/g) dan karotenoid (375.33 μmol/L) tertinggi. Kandungan vitamin C tertinggi (4.55 μg/g) terdapat pada sayuran sawi yang dibudidayakan di kawasan Wonorejo. Tidak ada perbedaan nyata pada kadar klorofil, karotenoid dan vitamin C antara sayuran organik dengan sayuran yang dibudidayakan di kawasan periurban Bangkingan-Lakarsantri.

Abstract

The developing of urban agriculture is having an important contribution in food supply to the citizen. One of urban agriculture commodity which is marketable is leaf vegetable, as the sources of protein, vitamin, minerals, essential amino acids that is cheap and available everydays. Even though the developing of urban agriculture commodity in the marginal land condition, but the result is a good product. This research conducted to make a comparison of nutrition value the leaf vegetable which planted in surabaya urban agriculture, such as Kangkung (Ipomea aquatic forsk), Mustard green (Brassica rapa), and Spinach (Spinacea oleracea L.), with its similar products which are produced organically. The method  used is descriptive quantitative. The total chlorophyll content and carotenoids are be measured by using spectrophotometric method at a wavelength of 480 nm, 645nm, and 663 nm.The content of vitamin C be measured by using the titration methods solution of Dichlorophenol Indophenol (DCPIP). The findings indicated that vegetable which planed in non organic agriculture, or organic, is having high enough in water content, more than 80%. The high vitamin C level is in non organic Mustard green (2,45 µg/g) and the lowest one in organic spinach (0,68 µg/g). The high chlorophyll level is in non organic spinach (23,81 mg/L) and the lowest one in non organic kangkung (3,29 mg/L). Likewise, the high carotene level is in non organic spinach (263,52 μmol/L) and the lowest one in non organic mustard green (168,02 μmol/L). The results of this study indicate that there is no particular type of leaf vegetables that has all the best nutrition value, both organic and non-organic. Pertanian perkotaan dikembangkan agar dapat memiliki kontribusi penting dalam memasok bahan pangan penduduk kota. Salah satu komoditi pertanian perkotaan yang cukup marketable adalah sayuran daun. Sayuran daun adalah sumber protein, vitamin, mineral, dan asam amino esensial paling murah dan tersedia setiap saat. Meskipun komoditi pertanian perkotaan dikembangkan di lahan yang marjinal, namun menghasilkan produk yang cukup baik. Penelitian ini dilakukan untuk membandingkan nilai gizi sayuran daun yang ditanam di pertanian perkotaan kota Surabaya, yaitu kangkung (Ipomea aquatic Forsk), sawi hijau (Brassica rapa), dan bayam (Spinacea oleracea L.), dengan produk serupa yang dihasilkan secara organik. Metode yang digunakan adalah deskriptif kuantitatif. Kandungan klorofil total dan karotenoid diukur dengan menggunakan metode spektrofotometri pada panjang gelombang 480 nm, 645 nm, dan 663 nm. Kandungan vitamin C diukur dengan metode titrasi larutan Dichlorophenol Indophenol (DCPIP). Hasil penelitian menunjukkan sayuran yang ditanam pada pertanian non organik, maupun organik, memiliki kadar air yang cukup  tinggi, yakni lebih dari 80%. Kadar vitamin C tertinggi pada Sawi non organik (2,45 µg/g) dan terendah pada bayam organik (0,68 µg/g).  Kadar klorofil tertinggi pada bayam non organik (23,81 mg/L) dan terendah pada kangkung non organik (3,29 mg/L). Demikian juga kadar karoten tertinggi pada bayam non organik (263,52 μmol/L) dan yang terendah pada sawi non organik (168,02 μmol/L).

Abstract

Pertanian di sekitar wilayah perkotaan ("periurban agriculture") mempunyai prospek ekonomis yang tinggi dan dapat dipacu menjadi tipe usahatani komersial. Usahatani yang demikian sangat cocok dikembangkan bagi masyarakat sekitar perkotaan yang pemilikan lahan umumnya sempit. Adanya pertanian di sekitar wilayah perkotaan, berarti akan mendekatkan produsen dengan konsumen, sehingga dapat mengurangi kerusakan produk dan biaya transportasi. Pengembangan pertanian periurban perlu dilengkapi dengan data sosial ekonomi usahatani dan karakteristik petani, dalam mengembangkan usahatani ke dalam bentuk agribisnis.    Produktivitas dan kualitas sumber daya manusia, dalam hal ini petani pada pertanian periurban, merupakan indikator dari komponen faktor sosial yang menjadi ciri karakter kawasan periurban. Sedangkan indikator komponen faktor ekonomi meliputi pertumbuhan ekonomi dan struktur ekonomi. Ada beberapa teknis analisis faktor, satu diantaranya adalah menggunakan metode analisis komponen utama (Principal Component Analysis).  Metode ini merupakan cara untuk mengekstraksi variabel asli, di mana terbentuknya faktor-faktor atau variabel laten baru adalah bersifat acak, yang selanjutnya dapat diinterpretasi sesuai dengan faktor atau komponen atau konstruk yang terbentuk. Penelitian ini bertujuan untuk mengidentifikasi karakter petani dan faktor-faktor yang menjadi latar belakang (konteks sosial ekonomi) serta pertimbangan petani untuk menekuni dan mengembangkan pertanian periurban.

Abstract

Various use of non-organic material is often applied in vegetable cultivation, it causes health problems for those who consume while the demand for the community will increase the need for vegetables. So it takes effort in the application of organic vegetable planting by utilizing the surrounding organic materials that are not used. Using of organic material also can increase time of harvesting, so more faster. Time of harvesting depends on growth of plants, more fertile of growing media, more faster plants can be harvested. The objectives of this study were: (1) to analyze the growth of mustard seedlings (Brassica juncea L.) (2) to get the best compositions for mustard seedlings. This research was conducted in Experimental Garden of Faculty of Agriculture of National Development University of "Veteran" East Java, Surabaya. In March to April 2017. This study was prepared in, Completely Randomized Design (RAL), with 8 treatments and 3 replications. The results showed that the addition of organic material can increase the growth rate of mustard plant seedlings in all treatments up to 4%/etmal and increase the percentage of plant growth of mustard seeds up to 90%. The result of the composition of the growing medium of P4 treatment is soil + compost + litter straw (2: 1: 1) can increase the number of leaves by 9,33 strands, plant length 38,80 cm, leaf area 60,80 cm2, dry weight 14,81 g, as well as the average total value of LTT (Plant Growth Rate) of 40% and LAB (Net Assimilation Rate) of 76% compared to using soil growth medium (P0).

Abstract

The use of planting media in a nursery, is crucial to the growing rate of seedlings. Plantingvegetable crops, becoming faster growing with its loose planting media, adequate nutritionand moisture are assured. Physically organic material in the form of compost straw, cocopeat,and corn leaves with indigenous technology capable of crumb soil medium so that the growthof seedling become assured. One factor study was the composition of growth media preparedin Completely Randomized Design (RAL) with 8 treatments and repeated 3 (three) times.Type of treatment as follows: P0 = Soil; P1 = Soil and Urea; P2 = Soil and Compost (2: 1); P3 =Soil, Compost and Cocopeat (2: 1: 1); P4 = Soil, Compost and Straw (2: 1: 1); P5 = Soil,Compost and Corn Leaves (2: 1: 1); P6 = Soil, Compost, Corn and Straw Leaves (2: 1: 1: 1); P7= Soil, Compost, Corn Leaf, Straw and Cocopeat (2: 1: 1: 1: 1). The results showed that thepercentage of seed germination at 5-7 days had reached 88% - 95%, germination rate of 4.53- 4,63 days by using composting medium of straw, cocopeat and maize leaf. The reduction ofsoil media is not significantly different from the use of soil alone or the use of urea + soil. Inthe length parameter of the plant, the number of leaves, leaf area and wet weight of the plantsdid not differ significantly between treatments, tended to be high at P4. P4 medium was ableto increase wet weight of seeds of mustard 53% and 38% compared to medium P0 (soil) andP1 (soil + urea)
