    (2016-07-28) Hasanah, Yaya; Nisa, Tengku Chairun; Hapsoh; Hanum, Hamidah
    Soybean is annual major crops in the world and important legumes in food security. Increased soybean production can achieve through increased in the intensity of soybean cultivation and expansion of soybean cultivation to marginal lands such as dry land. Nitrogen is a limited nutrient at dry land. The objective of this research was to determine the growth analysis of three soybean varieties on dry land with application of Nitrogen sources. Research using randomized block design with 2 factors and 3 replications. The first factor is soybean varieties (Anjasmoro, Wilis and Sinabung). The second factor is the sources of N consists of without application of N, Urea 50 kg/ha, Bradyrhizobium sp., manure 10 tons/ha and combinations of Bradyrhizobium sp. + manure 5 tons/ha. The research result shown that Anjasmoro variety significantly increased the relative growth rate and net assimilation rate 5-6 WAP compared with Sinabung and Wilis. Application of Bradyrhizobium sp. significantly increased the plant growth rate and relative growth rate 5-6 WAP compared with other N treatments. Combination of Bradyrhizobium sp. and manure 5 tons/ha on Anjasmoro variety tent to increase the net assimilation rate 5-6 WAP.

    GROWTH AND YIELD RESPONSES OF GINGER (Zingiber officinale Rosc.) TO SOLID ORGANIC FERTILIZER AND COMPOSITION OF PLANTING MEDIA
    (2016-07-28) Hapsoh; Hasanah, Yaya; Rahmawati, Nini
    The objective of the research was to study the response of ginger (Zingiber officinale Rosc.) grown in baskets system, in terms of growth and yield to the application of solid organic fertilizer and composition of planting media. The research used Factorial Randomized Complete Block Design with 2 factors and 4 replications. The first factor was solid organic fertilizer which consisted of 2 treatments: without and with solid organic fertilizer. The second one was composition of planting media with 4 treatments which consisted of compost: sand=2:1; compost: paddy chaff= 2:1, top soil: cow manure: sand= 3:1:1 and top soil: manure: paddy chaff= 3:1:1. The results showed that solid organic fertilizers had promoting effects on ginger growth and yield as shown by increasing bud number and rhizome weight per plant. The mixture of top soil: manure:sand/paddy chaff of 3:1:1 was the best planting medium for zinger growth

    Isoflavone characters of three soybean varieties under drought stress with application of nitrogen sources
    (2016-07-28) Hasanah, Yaya; Nisa, Tengku Chairun; Hapsoh; Hanum, Hamidah
    Human interest in soybean greathyincreasedin recent years due to the positive effects of secondary metabolites in soybean such as isoflavones for human health. Isoflavones are phytoestrogens worked as the antioxidant and chemopreventive agents for estrogenic compounds that can inhibit cell proliferation. Isoflvones also serves to prevent heart damage, osteoporosis and manaupose syndrome, prevent prostate, colon cancer and breast cancer. Daidzein, genistein and glycitein are the major isoflavones in soybean. A research about isoflavone characters of three soybean varieties under drought stress with application of Nitrogen sources was conducted in green house, Faculty of Agriculture,University of Sumatera Utara. The aim of the research was to study the effect of Nitrogen sources under drought stress on isoflavone characters of three soybean varieties. The experiment used a Factorial Randomized Block Design with three factors and three replications. The first factor was soybean varieties consisted of Anjsmoro, Wilis and Sinabung. The second factor was Nitrogen sources consisted of without N fertilizer application; Urea 50 kg/ha, Bradyrhizobium sp., cow manure 10 t/ha, rice straw compost 10 t/ha. The third factor was soil water content condition namely 50%, 60%, 70 and 80% of field capacity. The parameters observed were isoflavone characters consisted of genistein, daidzein, glycitein and isoflavone total. The result showed that Anjasmoro variety had the genistein, daidzein, glycitein and isoflavone total contents of soybean higher than Wilis and Sinabung. The Application of Nitrogen sources increased the genistein, daidzein, glycitein and isoflavone total contents of soybean compared without application of Nitrogen sources. There is a distinct pattern in the increase in the isoflavone total content in Anjasmoro, Wilis and Sinabung with increasing the drought stress, At Anjasmoro variety, increasing drought stress caused the lower of isoflavone total content, while the varieties Sinabung and Wilis are opposite pattern.

    Isoflavone content of soybean [Glycine max (L). Merr.] cultivars with different nitrogen souces and growing season under dry land conditions
    (2016-07-28) Hasanah, Yaya; Nisa, Tengku Chairun; Hapsoh; Hanum, Hamidah
    The objective of the research was to determine the best N nutrient management for isoflavone content in three soybean cultivars under dry land conditions. Two experiments were experiment I (June to September 2012 growing season) and Experiment II (October to December 2012 growing season). Experimental design was a randomized block design with 2 factors and 3 replications. The first factor was soybean cultivars (Anjasmoro, Wilis, Sinabung). The second factor was N source, with Urea (50 kg/ha), Bradyrhizobium sp., farmyard manure (10 ton/ha), a combination of Bradyrhizobium sp. + farmyard manure (5 ton/ha) and a control with no N. A combined analysis of variance was done to evaluate the production and the content of isoflavone in the two different growing seasons as affected by N source and cultivar. The parameters observed were the content of genistein, daidzein, glycitein and total isoflavone content. Results showed that the October to December growing season had higher genistein, daidzein, glycitein and total of isoflavones than the June to September growing season. The treatment cultivar Wilis plus Bradyrhizobium sp. grown at October to December growing season increased total isoflavone content more than other treatments.

    PENERAPAN TEKNOLOGI BIOAKTIVATOR UNTUK MENINGKATKAN PRODUKSI DAN KUALITAS KOMPOS DARI LIMBAH PERTANIAN
    (2016-08-09) Hapsoh; Hasanah, Yaya; Rahmawati, Nini
    Dewasa ini kesadaran masyarakat dunia terhadap kelestarian lingkungan semakin meningkat. Hal tersebut ditandai dengan adanya trend dunia untuk “kembali ke alam” (back to nature). Masyarakat dunia modern pada abad ini lebih menyukai pertanian organik dan menyadari akan pentingnya pembangunan ramah lingkungan. Pertanian organik mengandung pengertian bahwa semua pupuk dan pestisida yang digunakan terbuat dari bahan-bahan organik, seperti kompos dan pestisida nabati. Desa Cinta Air Kecamatan Perbaungan Kabupaten Serdang Bedagai merupakan salah satu sentra pertanian organik, khususnya jahe dengan sistem keranjang dan jagung. Untuk meningkatkan produksi pertanian organik tersebut para petani di desa ini memerlukan kompos dalam jumlah yang sangat banyak, karena kompos merupakan pupuk utama dalam pertanian organik. Kompos tersebut dipenuhi oleh UKM Bumi Sekar yang terdapat di desa tersebut. UKM Bumi Sekar memproduksi kompos dengan cara yang sangat sederhana yaitu memproduksi kompos dari jerami padi dan limbah kelapa sawit yang telah tertimbun bertahun-tahun dengan cara mengambilnya tanpa pengolahan lebih lanjut. Cara pengambilan kompos demikian beresiko tinggi karena pekerja UKM harus mengambilnya dari sebelah bawah (jerami padi dan limbah kelapa sawit yang telah tertimbun bertahun-tahun), disamping itu kualitas kompos tidak terjamin

    The aim of the research was to know the response of growth and production of ginger in crate system on solid organic fertilizer and the composition of planting media. The research used Randomized Complete Block Design Factorial with 2 factors and 4 replications. The first factor is solid organic fertilizer namely without and with solid organic fertilizer. The second one is manure: sand =2:1, manure : paddy chaff = 2:1, topsoil : manure : sand = 3:1:1, top soil : manure : paddy chaff = 3:1:1.the result research showed that solid organic fertilizer give the good effect on growth and production of zinger was shown by increasing number of buds and rhizome weight/plant. The composition of planting media namely top soil: manure : sand/paddy chaff (3:1:1) gave the best ginger growth. Keywords: ginger, planting media, solid organic fertilizer.
