Abstract

Peatland degradation occurs because of the activities carried out on the land. This study aims to determine the effectiveness of Mucuna bracteata in controlling peat soil degradation in oil palm plantations and the effect of Mucuna bracteata age on peat soil degradation in oil palm plantations. This research was conducted by the survey method. The determination of the research location is done by a purposive sampling method. The type of location is peatland planted with oil palm and applied with Lagume Cover Crop Mucuna bracteata (LCC MB) without LCC MB aged 3, 4, and 5 years. Each location was studied with four replications. The soil physical properties and soil chemical properties (pH, C-organic, N-total, P-available, K-total, CaO, ash content, electrical conductivity, and redox potential) were measured. Peatland planted with oil palm and LCC MB applied was able to control the degradation of physical properties (air holding capacity and volume of weight) and chemical properties (ash content, N-total, P-available, K-total pH, and CaO) compared to those not applied. LCC MB. Peatland planted with oil palm and applied to LCC MB until the age of 3 years was able to control the chemical properties (P-available and K-total), but further increases in the age of LCC MB (4 and 5 years) were no longer effective in controlling the properties of the peat soil. Peatland planted with oil palm and applied to LCC MB was able to control the chemical properties (electrical conductivity and ash content), up to the age of 4 years, but a further increase in the age of LCC MB (5 years) was no longer effective in controlling the properties of the peat soil because it no longer experienced intensive growth.

Abstract

Soybean  is  a  legume  sensitive  to  drought  conditions  resulting  in  decreased  yield  and  seed quality.  Drought stress on plants also inhibits nitrogen uptake.  The objective of the research was to  determine production and physiological characters  of soybean varieties under drought stress through nutrient N management. This research used a randomized block design with  3 factors  and  3  replications.  The  first  factor  was  soybean  varieties  (Anjasmoro,  Wilis  and Sinabung). The second factor was drought stress conditions consisted of 50%, 60% , 70% and 80%   of field capacity (FC). The third factor was the application of N consisted of (1). Without application of N fertilizer (control);  (2). N fertilizer dose of recommendation (50 kg Urea/ha); (3). Inoculation of Bradyrhizobium sp. ; (4). Organic N sources (straw compost 10 tons/ha)  ; (5).  Organic  N  sources  (farmyard  manure  10  tons/ha).  The  results  suggest  that  Anjasmoro variety  improved dry weight of seed per plant compared with Willis and Sinabung.   Increased drought stress ( 80-50 % of FC) resulted in a decrease in dry weight of seed per plant. Sources  of  N  in  the  form  of  urea  or  Bradyrhizobium  sp.  increased  the  dry  weight  of  seeds  per  plant compared  with  treatment  N  sources  straw  and  manure  compost.  The  interaction  between Bradyrhizobium sp.  or Urea and Anjasmoro variety improved  dry  weight of seeds per plant

Abstract

Human interest in soybean greatly increased in 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 cellproliferation. Isoflavones also serves to prevent heart damage, osteoporosis and menopause syndrome, prevent prostate cancer, colon cancer and breast cancer. Daidzein, genistein and glycitein are the major isoflavones in soybean. A research about isoflavone charácters of three soybean varieties under droughtstress 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  andomized Block Design with three factors and three replications. The first factor was soybean varieties consisted of Anjasmoro, 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 charcters consisted of genistein, daidzein, glycitein and isoflavone total. The resultshowed 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 Nitrogensources. 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 elower of isoflavone total content, while the varieties Sinabung and Wilis are the opposite pattern

Abstract

AbstrakRendahnya produktivitas tanaman padi maupun hortikultura di desa Langsat Permai Kecamatan Bunga Raya Kabupaten Siak salah satunya disebabkan karena belum tersedianya air yang cukup untuk budidaya tanaman sehingga perlu dilakukan pengelolaan tata air dengan pembuatan canal blocking untuk dapat dimanfaatkan pada tanaman padi maupun tanaman hortikultura di daerah tersebut. Hal ini dilakukan untuk memenuhi kebutuhan air pada tanaman padi maupun hortikultura apalagi pada saat musim kemarau. Oleh karena itu, dilakukan pendampingan melalui kegiatan IbDM pengelolaan tata air di Desa Langsat Permai Kecamatan Bunga Raya Kabupaten Siak. Selain pengadaan air, peningkatan budidaya pertanian dapat dilakukan dengan memanfaatkan limbah jerami untuk dijadikan kompos dan pakan ternak sehingga dapat membentuk pertanian terpadu antara aspek pertanian dan peternakan. Strategi pendampingan dilakukan dengan berdiskusi secara langsung dengan kelompok tani mengenai dampak pembuatan canal blockingdan praktek langsung dalam pembuatan kompos dan pakan ternak. Melalui kegiatan ini sangat terlihat antusias masyarakat dalam pelaksanaan kegiatan IbDM yang dilakukan melalui peningkatan motivasi masyarakat untuk pengembangan tanaman pangan dan hortikultura serta lebih memanfaatkan jerami padi untuk kompos dan pakan ternak.Kata Kunci : canal blocking, jerami padi, kompos, pakan ternak AbstractThe low productivity of rice crops and horticulture in Langsat Permai village, Bunga Raya subdistrict, Siak regency is caused by the lack of sufficient water for the cultivation of plants, so it is necessary to manage the water system by making canal blocking to be used in rice crops and horticultural crops in the area. This is done to meet the water needs in rice crops and horticulture especially during the dry season. Therefore, assistance is done through the activities of IbDM water management in the Village Langsat Permai District Bunga Raya Siak District. In addition to water supply, improved agricultural cultivation can be done by utilizing the waste of straw to be used as compost and animal feed so as to form an integrated agriculture between aspects of agriculture and livestock. Advisory strategy is conducted by discussing directly with farmer groups about the impact of canal blocking and direct practice in composting and animal feed. Through this activity is very visible enthusiastic community in the implementation of IbDM activities conducted through increased community motivation for the development of food crops and horticulture and more use of rice straw for compost and animal feed.
