Abstract

The potential of  Exotic  Earth worm  Endogeik  (Pontoscolex corethrurus)  for Production Vermikompos    granules (Vermigran) Local Organil-Based Materials. In 2011, total demand for  organic fertilizer in Indonesia was 12.394 million tons and 2.601 million tons  of new available. This requirement will continue to increase until 2015, so the  opportunity   to   develop   great organic fertilizer. One  disadvantage  of the  use of organic fertilizers is very much in    volume (bulky), it is necessary    vermikompos manufacturing  innovation in   the   form   of granules to   be   more efficient   in   the applicationand transport. Research objectives are: (1) study the potential     of earthworms in producing vermikompos Pontoscolex    corethrurus of l local organic ingredients, and (2)produce quality vermikompos in the form of  granules.  The study    was   conducted in   a   greenhouse Fak. Agriculture and in   the   yard   of a house in Ngesrep,   Boyolali, in July-November 2011. The     study design using a Completely  Randomized Design, factorial,two factor. Factor 1 is  composed of three types  of  worms   cedar, and  the  second  factoris  the variation  of the  type of organic material, consisting of 7 cedar. The variablesmeasured were vermikompos nutrient quality and speed  of the  water  solubility  vermikompos   granules. The  results showed  that  Pontoscolex corethrurus high potentialto produce vermikompos  that meet ISO   quality   compost.   Cow   pile, pile quail, water  hyacinth   can  be  used as  a  raw material   vermikompos.   Clay,   starch, starch and claymixture (1:1) can be  used as  an adhesive vermikompos granules (vermigran) soluble in   water at <48 hours. Production vermigran great potential for   developmentas a high-quality organic fertilizer.

Abstract

Utilization of farm wastes in order to realize the concept of integrated farming is a sustainable agriculture community service program in cooperation with two partners , namely : ( 1 ) quail - catfish Breeders Agribird , and ( 2 ) dairy farms and agricultural businesses " Andini Mulyo " . This service activities conducted through outreach / awareness , mentoring and manufacture of demonstration plots . Preparation of demonstration plots to make an example of earthworm cultivation ( vermikultur ) and the making of silage . Testing vermicompost and organic fertilizer from cow dung to plant corn and kale using plots measuring 50 x 9 meters , divided into 3 blocks , each 3 x 50 meters . Outcome in the form of products include : Biomass earthworm number 5 Kg / month ; Vermicompost 50 Kg ; Silage , 300 Kg once manufacture ; and quality organic fertilizer from cow dung , 600 kg / process . Outcome in the form of a test product to the plant : the use of manure , vermicompost fertilizer in Litosol very real increase maize crop which includes fresh weight of corn stover , corn stover dry weight and dry weight of seed corn ; the use of manure and fertilizer plants in the ground grumosol not significantly different with kale stover fresh weight , while the use of vermicompost highly significant increase stover fresh weight of spinach

Abstract

Produksi padi di Indonesia masih belum mampu menutupi kebutuhan nasional. Rendahnya produktivitas ini salah satunya disebabkan oleh penurunan tingkat kesuburan tanah. Salah satu cara untuk meningkatkan kandungan fosfat didalam tanah adalah dengan memberikan pupuk fosfat alam dan juga inokulum azolla. Penelitian ini dilakukan untuk mengetahui dosis yang tepat dari inokulum azolla dan fosfat alam untuk meningkatkan ketersediaan fosfat dan meningkatkan hasil tanaman padi pada tanah alfisol. Penelitian ini menggunakan metode RAL faktorial dengan dua faktor pembanding perlakuan pupuk kandang dan pupuk N,P,K. Analisis data hasil pengamatan menggunakan analisis ragam pada taraf 5% dan apabila terdapat pengaruh beda nyata dilanjutkan dengan uji DMRT taraf 5% untuk membandingkan antar perlakuan. Hasil penelitian menunjukan bahwa perlakuan pemberian inokulum azolla dan fosfat alam dapat meningkatkan ketersediaan fosfat pada tanah alfisol dan mampu meningkatkan hasil padi. Pada parameter P tersedia hasil tertinggi menunjukan pada perlakuan azolla 2,5 ton/ha tanpa fosfat alam dan azolla 5 ton/ha fosfat alam 350 kg/ha yaitu 10,81 ppm. Selain itu pemberian inokulum azolla dan fosfat alam memberikan peningkatan terhadap kadar KTK, bahan organik, N total dalam tanah dan pH tanah.

Abstract

The eruption of Merapi mountain has primary and secondary hazard and may damage to the land. In detail, the hazards are land degradation is a loss of some or many of germplasm and changes in plant biodiversity. The others hazard including loss of water catchment areas, the destruction of forests, and even the closing of the water source, as well as the loss of water channels. The burried of soil and soil formation inhibition were caused by the repeated eruptions of Merapi, beside the loss of roads access to agricultural land and loss of land ownerships boundaries by the eruption and cool lava. Materials of eruption are sand and pyroclastic materials, as well as the nature of cementation require special techniques and technology to use the land as new farmland. Land restoration efforts can be done with the land management by reforestation on government-owned land for water catchment function, agroforestry forage grass based, grazing field on land owned by the village and residents, with the use of organic materials in the eruption sandy soil ameliorant.

Abstract

Endrin residues are still remain in the  land field these compounds are no longer used by farmers and have been banned by the government. This residue can stay in the soil longer and persistant. Microbial enrichment is expected to accelerate the degradation of pesticide residues. Microbes stretcher are Bacillus substillis, Heliothrix oregonensis, Catenococcus thiocycli, and Achoromobacter sp obtained from the preliminary research results  from soil isolation of idegenus in LIPI Cibinong Microbiology Laboratory.  Soil for the planting medium obtained from the village of Karawang, Regency Cilamaya Wetan, Cilamaya District. The experiment was conducted in the field by using lysimeter at the Experiment Jakenan station from July 2013 to December 2013. The objective of the research is to obtain technology of activated carbon-coated urea and biochar which  enriched microbial indegenus. The experiment was used randomized block design (RAK) with 3 replications.  Plant used are rice. Insecticide residue analysis was carried out in the laboratory in Bogor Balingtan using gas chromatography (GC), with the SNI method 06-6991.1-2004. The purpose of this study knowing the capabilities of urea coating with activated carbon enrichment microbia in reducing the concentration of residues endrin. Results of research urea coated activated carbon from coconut shell are enriched with microbes on paddy field can lower pesticide residues of endrin respectively to 33.6%.  This is presumably due to the role of microbes degrading effective as activated carbon as the preferred home. Enrichmentwith microbial indegenuscan improve theeffectivenessof ureacoating biochar andureacoatingactivated carbon coconut shell todecrease concentration endrin.
