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

Recently ecological services by macrofauna diversity to sustainable production function of agroecosystem got a lot of attention. Epigeic macrofauna is diverse of macrofaunas which their life and activities are on the land surface, act as decomposer, litter transformer, and`predator, so they are important to keep ecosystem stability. Inorganic fertilizer usage continually on carrot crop without organic fertilizer can reduce soil macrofauna diversity. Improvement can be done by the use of organic and inorganic fertilizer equally. The aim of this research was to measure epigeic macrofauna diversity and their ecological services to carrot production by giving some proportions of organic and anorganic fertilizer. The research conducted in the end of December 2007 in a farmer field in Tawangmangu. It use RAKL (Random Completly Block Design) with single factor treatment. The treatment was fertilizer type usage proportion of organic and inorganic fertilizer. They were composed of 9 proporsition composition as follows: control, 50% inorganic fertilizer, 100% inorganic fertilizer, 50% organic fertilizer, 50% organic fertilizer added by 50% inorganic fertilizer, 50% organic fertilizer added by 100% inorganic fertilizer, 100% organic fertilizer, 100% organic fertilizer added by 50% inorganic fertilizer, 100% organic fertilizer added by 100% inorganic fertilizer. 100% inorganic fertilizer were composed of Urea 150 kg ha-1, SP 36 200 kg ha-1, and KCL 100 kg ha-1. 100% dosage organic fertilizer was 20 tons ha-1. To recognize the treatment effect is done by F test and close relationship among variables tested by corelation analysis. The result showed that organic and inorganic fertilizer proportion didn’t significant to diversity, population dencity and biomass epigeic macrofauna, but affected to β caroten content of carrot. Hymenoptera was dominant macrofauna in carrot crop. Macrofauna function to increase β caroten of carrot is indirect. Key words: fertilizer proportion, epigeic macrofauna, β caroten, Hymenoptera, ecological service

Abstract

Masalah kekahatan hara cenderung meningkat, termasuk kekahatan sulfur. Penggunaan pupuk NPK berkemurnian tinggi ikut mendorong terjadinya kekahatan hara di lahan pertanian. Masalah kekahatan hara ini dapat diatasi melalui penggunaan sulfur elementer yang disertai denngan pupuk hayati pengoksidasi sulfur. Penelitian bertujuan untuk mengkaji potensi mikrobia pengoksidasi sulfur yang diisolasi dari tanah Andisol Dieng, Jawa Tengah sebagai inokulan untuk pupuk hayati. Tanah Andisol Dieng secara alamiah mengandung sulfur yang cukup tinggi sehingga diperkirakan dihuni oleh banyak mikrobia pengoksidasi sulfur. Penelitian terdiri dari dua percobaan, masing-masing disusun dalam rancangan percobaan acak lengkap dua faktor, yaitu macam isolat mikrobia hasil isolasi dari Andisol Dieng dan lama inkubasi. Percobaan pertama menggunakan medium cair Czapek-dox + sulfur sedangkan percobaan kedua menggunakan medium vermikompos. Tiap-tiap kombinasi perlakuan diulang tiga kali. Variabel yang diamati meliputi jumlah S terlarut, kerapatan sel bakteri atau biomassa jamur dan pH medium. Dari hasil eksplorasi diperoleh satu isolat bakteri I1 dan tiga isolat jamur F1, F2 dan F3 yang menunjukkan kemampuan mengoksidasi sulfur pada medium Czapek-dox+ sulfur elementer agar. Hasil percobaan menunjukkan bahwa proses oksidasi sulfur meningkat seiring dengan bertambahnya waktu inkubasi yang ditunjukkan oleh meningkatnya jumlah S-terlarut, kerapatan sel bakteri atau biomassa jamur dan menurunnya pH medium. Hasil serupa diperoleh dari percobaan kedua. Isolat jamur F2 menunjukkan potensi yang paling tinggi sebagai inokulan pengoksidasi sulfur yang ditunjukkan oleh kemampuannya tumbuh dan mengoksidasi sulfur yang paling tinggi baik pada medium cair Czapek-dox + sulfur maupun pada medium vermikompos.

Abstract

Rice production in Indonesia can not cover the national needs. The low productivity caused by the decline in soil fertility. One way to increase the phosphorus content in the soil is to provide natural phosphate fertilizer and Azolla inoculum. This study was conducted to determine the proper dose of Azolla inoculum and rock phosphate to increase the availability of phosphate and increase the yield of rice plants on land Alfisol. This study uses the two-factor factorial CRD comparative treatment of manure and fertilizer N, P, K. Analysis of the observed data using analysis of variance at 5% level and if there is a significant difference effect followed by DMRT 5% level to compare between treatments. The results showed that treatment of Azolla inoculum and phosphate can increase the availability of phosphate in the Alfisol soil and can increase rice yield. On the parameters available P showed the highest results in the treatment of Azolla 2.5 tons / ha without natural phosphate and Azolla 5 tons / ha of natural phosphate 350 kg / ha which is 10.81 ppm. In addition, administration of Azolla inoculum and phosphate levels give rise to CEC, organic matter, total N in the soil and soil pH.

Abstract

Forest conversion to agriculture systems leads to change on litter input (quantitatively and qualitatively) resulting lower diversity, population density and biomass of earthworm. Litter with ratio C/N <20, or ratio of (lignin (L)+polifenol (P))/N <10 classified as high quality which decomposed rapidly. Six types of litter application were tested i.e. prunning of cofee with the lowest (L+P)/N of 7.5, Gliricidia (L+P)/N of 10, avocado with (L+P)/N of 31, Cofee+Gliricidia with (L+P)/N of 12, Cofee+Gliricidia+ avocado with the highest (L+P)/N of 64. As control soil without litter application was used. Applying tree litters regardless their quality increased significantly (p<0.05) all growth parameters of earthworm, except for Gliricidia application lead to higher level of earthworm mortality starting at 20 days after treatment. Applied a low quality of avocado litter to the soil produced the highest biomass (0.79 g/indiv.), diameter (2.42 mm/indiv.) and length (6.13 cm/indiv.). Mixing coffee litter with Gliricidia litter increased earthworm mortality (5.5% to 42.5%) and reduced production of cocoon (2 become 0 cocoons) compared to coffee applied alone. Coffee+Gliricidia+Avocado lead to longer live earthworm up to 80 days Apparently Gliricidia litter producing chemical substances which harmful to earthworm.Keyword: earthworm, litter quality, forest conversion
