Club root caused by P. brassicae is the most important disease of Brassicaceae. In the fields, the pathogen can totally fail to harvest. The disease is difficult to control, because the pathogen can persist in soil far years although there is no host. Elimination of the pathogen in the infested soil is become an important tactic in control of soil born disease such the disease. The use of natural agents which save on environment is one of the interesting methods to develop. One of them is rock salt (NaCl). An evaluation of the effectiveness of NaCl for elimination of club root pathogen and its impact on growth of Chinese cabbage as indicator plant has been conducted. A mount of 13 factorial treatments consisted of 5 levels of concentration and 5 levels of frequency of dreanching application have been evaluated. The result showed that the soil drenching of NaCl dilution with some concentration and time application were effective to control club root on Chinese cabbage. A concentration of 0,5-1% NaCl could be considerable for control of club root on Chinese cabbage. Soil drenching of NaCl solution on two or one weeks before planting could be considerable in control of club root.

Efficacy of livestock is very determined by feeds. High or low livestock production depending on amount and feeds quality given, either in sheep production. Sheep will not be optimal production if only given by grass, so it needed supplement by other feeds materials contains high nutrition materials like legume and concentrate.By giving concentrate to sheep, it can improve growth, flesh production and also crabbed weight. But used of concentrate require to be considered. Because it’s costly is price so that can cause the expense of feeds become high. Therefore require to be searched by alternative materials which in big supply, easy to get, its price cheap but can support high production, and have no or a little competition with use for the livestock of other livestock for example poultry and ruminant. One of the materials is industrial disposal processing of soy. At processing of soy become Tempe or ketchup, it is produce waste in the form of Tempe dregs, Tofu dregs and ketchup dregs. Seen from its nutrient content, especially harsh protein and energy, the dregs have potency to be used as livestock feeds, especially upon which supplementation in feeds of sheep livestock.

Tujuan umum penelitian ini adalah memetakan potensi produksi emisi metana pada lahan sawah organik di Desa Sukorejo dan Jetis, Kecamatan Sambirejo, Sragen, yang dapat digunakan untuk memitigasi emisi metana dan meningkatkan produktivitas lahan. Secara garis besar pelaksanaan penelitian dibagi menjadi 4 tahap ; (1) karakterisasi tanah dan lahan, pengungkapan secara mendalam karakter obyek lahan pada setiap satuan penggunaan lahan sawah, (2) pengukuran potensi produksi emisi metana, dengan metode inkubasi sampel tanah di laboratorium, sampel gas yang dihasilkan dianalisis menggunakan kromatografi gas yang dilengkapi dengan flame ionization detector (FID) untuk menetapkan flux CH4, (3) analisa data, taraf perbedaan nilai potensi produksi metana diketahui dengan analisis beda nyata Uji T, dan penentuan faktor yang paling berperan terhadap besarnya potensi emisi metana dengan analisis stepwise regression, dan (4) rekomendasi, pemilihan rekomendasi didasarkan pada praktek budidaya pertanian yang efektif meningkatkan C organik dan menekan produksi emisi metana tanpa mengurangi produktivitas tanaman. Hasil penelitian menunjukkan bahwa ; (1) potensi produksi metana (CH4) berbeda nyata antar satuan penggunaan lahan (SPL) sawah di Desa Sukorejo dan Jetis, (2) iklim, varietas tanaman dan cara budidaya di daerah penelitian tidak signifikan mempengaruhi besarnya potensi produksi metana, dan (3) faktor yang berpengaruh signifikan terhadap besarnya potensi produksi metana di tanah sawah adalah potensial redoks (Eh). Hubungan Eh dengan besarnya potensi produksi metana berkorelasi negatif, artinya penurunan Eh akan menyebabkan peningkatan produksi metana. Mitigasi emisi GRK metana yang dapat dilakukan berdasarkan penelitian ini, bahwa potensial redoks adalah faktor utama penentu potensi produksi metana di dalam tanah sawah, maka alternatif yang memungkinkan adalah dengan pengelolaan air irigasi, yang dalam periode tertentu tanaman padi tidak diairi atau tidak digenangi, atau apabila kondisi air berlebih dilakukan drainase. Usaha ini dilakukan dengan tujuan kondisi tanah tidak terlalu reduktif atau potensial redoks tidak akan turun secara drastis, sehingga akan dapat menghambat aktivitas mikrobia methanogen dalam memproduksi metana.
