Abstract

Symbiotic nitrogen fixationis a key factor in the low-input farming systemto sustain long time soil fertility. Symbiotic nitrogenfixation involving host-specific symbiotic interactionsbetween root nodule bacteria, termed rhizobia,and legumes. One of the major strategies forenhancing symbiotic nitrogen fixation by legumesin crop production systems is through rhizobialinoculation. But inoculation not always successfuland one reason is the population of indigenous rhizobiumcontained in the soil. Indigenous rhizobium cancompete with rhizobium inoculant through populationdensity and effectiveness. The high populationof rhizobium in one place relating to the type oflegume that ever grew / grown. When the numberof indigenous population is low, not effective or notcompatible with legumes planted the rhizobiuminoculation is required. But when the number ofindigenous rhizobium population is high, effectiveand compatible with legumes that will be planted(based on observations of root nodules and existingplants), inoculation is not required.

Abstract

Salah satu inovasi teknologi yang mampumeningkatkan produktivitas kedelai adalah varietasunggul. Sejak tahun 1918 sampai 2009, setidaknyaada 72 varietas kedelai yang telah dilepas dan disebarkankepada petani. Bermacam-macam mekanismedifusi telah diterapkan kepada petani, tetapitingkat keberhasilannya masih rendah, sehinggabanyak teknologi kedelai yang dihasilkan tidak terpakaioleh petani alias mubazir. Dominasi penggunaankedelai varietas Wilis sampai saat ini oleh petanisudah berlangsung selama 28 tahun sejak dilepasvarietas tersebut. Setelah berjalan 10 tahun varietasAnjasmoro dikeluarkan yakni tahun 2001, nampakmulai ada kecenderungan varietas tersebut untukmenggeser varietas Wilis di petani. Melihat perkembangnanproses difusi teknologi kedelai VUB belumberjalan efektif tersebut betapa cukup lama waktuyang dibutuhkan teknologi tersebut sampai digunakanpetani. Suatu keberhasilan difusi teknologi tidakhanya diperoleh dari satu kegiatan diseminasi, tetapidari berbagai kegiatan yang saling mendukung(penelitian, perbenihan, promosi) dan memerlukanwaktu untuk memperolehnya. Perlu perubahan paradigmadiseminasi yang tidak hanya bersifat seremonialseperti kunjungan dalam panen raya, pameran/temu lapang dengan menyebarkan brosur/leaflet,memutar film (video) tetapi disertai informasi cukupdalam akses kehadiran fisik atau penyediaan barang/benih yang nyata di tingkat pengguna (petani)

Abstract

Bacterial wilt caused by Ralstonia solanacearumis an important disease constraint of groundnut(Arachis hypogaea L.) in tropical and subtropical allover the world. It causing yield losses of 15–35%,and may reach over 65% in groundnut susceptiblevarieties. In Indonesia, the disease have been foundin some areas in North and West Sumatra, Lampung,West Java, Central Java, East Java, Bali, North andSouth Sulawesi. The wilt symptoms can be observedthree weeks after sowing. Infection of plants resultsin rapid wilting of stems and foliage, while leavesretain their green color.There is no desirable method for chemical controlof groundnut wilt, although some bactericidesthat effective against R. solanacearum have beenidentified and available commercially. Other controlstrategy by non-chemically include resistant varieties,healthy seeds, healthy cultivation, biologicalcontrol, and botanical control have been reduced thedisease. Other disease control strategies which ereenvironment-friendly are resistant variety, and theuse of bio control agents. Resistance variety is oneof the most effective means of controlling groundnutwilt and effective to control bacterial wilt in endemicarea and this method could be adopted byfarmer easily. Biocontrol agents i.e. antagonisticbacteria Psudomonas fluorescens (Pf) isolated fromlegumes rhizosphere showed inhibited effect againstbacterial wilt R. solanacearum. The plants extractof some plants such as lemon grass and nut sedgeroots, also showed suppressive effect against bacterialwilt of groundnut.

Abstract

Fresh cassava rots are perishableif not treated immediately after harvest,because it has high of water content (65%). Processingof cassava into intermediate product such as flourcan be developed in the producing areas, because itis easily practiced by farmers with simple equipment.Flour can be further processed into a variety of foodproducts. Cassava flour processing technology is animprovement of cassava flour processing. Currently,modified cassava flour processing technologyhas beendeveloped by adding a starter during fermentation/immersion. This resulted in better quality of theflour, such as whiter colour, reduced spesific aromaof cassava, and the increase in peak viscosity. It canbe used as a substitute of wheat flour, rice flour orglutinous rice flour about 15–30%, for as cakes,muffins, and noodles. Application cassava flour, bothmodification and without modification is prospectiveto be developed in term of supporting food diversificationprogram in Lampung Province as a centerof cassava production in Indonesi

Abstract

Mungbean (Vigna radiata) are resistant to drought and the price relatively high and stable compared than other legumes. In Demak district, mungbeans grown in the dry season after rice in heavy soil (Vertisol), without tillage, wihtout weeding and irrigation. The main problem on mungbean cultivation are drought and pest attacks.The intensity of pest attacks can be suppressed by pesticides. While drought can be avoided by planting 3–5 days after the rice harvested. Planting intimely way, the use of early maturity varieties and uniform maturity of pod (Vima 1) accompanied by an intensive pest control in the Tempuran and Megonten village Demak district can provide high yields, ranging from 1.72 to 1.92 t/ ha. The cost of production is needed between Rp 2.926.000 – Rp3.167.000/ha, can provide benefits ranging between Rp 7.669.000 million – Rp 8.594.000/ha and B/C ratio from 2.42 to 2.90. The application of introduction technology using Vima 1 variety that farmers do a positive impact on benefits which reached Rp 12.210.814,- (B/C ratio3,22), so its worth in the region has developed just as in the areas of agroecology Demak. The use of variety Vima 1 for 2 years after the technology display has covering 2000 ha in the Demak district, in order to accelerate the adoption of the technology it need to be disseminated effectively assembled this technology through the display of this technology insome areas that has the same condition. Local Government and relevant agencies should be involvedso that effective dissemination of technology.
