Penggunaan varietas unggul merupakan salah satu metode perbaikan teknis budidaya yang sangat eratkaitannya dengan peningkatan produktivitas padi sawah. Kegiatan Kajian Varietas Unggul Baru Inpari 30dilaksanakan di Kelompok Tani Dalima, Kelurahan Situgede, Kec. Bogor Barat, Kota Bogor. Kegiatandilaksanakan dengan menerapkan rekomendasi teknologi dan cara petani pada lahan sawah milik petani denganpetakan alami. Tujuan penelitian untuk mengetahui adaptasi VUB Inpari 30 dan rekomendasi teknologi di wilyahKota Bogor. Peubah yang diamati yaitu: Tinggi tanaman (30, 60 dan 90 HST), komponen hasil (jumlah gabah isiper malai dan jumlah gabah hampa per malai dan produktivitas). Data dianalisis dengan Uji t test. Analisismenggunakan SPSS versi 20 for windows. Hasil penelitian menunjukkan bahwa Teknologi Jajar Legowo Superdengan menggunakan Varietas Unggul Baru (VUB) Inpari 30 mencapai produktiviats sebesar 7,60 t ha-1.Kata kunci : Varietas Unggul Baru, Jajar legowo superABSTRACTThe use of improved varieties of the methods of cultivation technical improvement that is closely related tothe increase of rice field productivity. Assessment of new superior varieties Inpari 30 was conducted at DalimaFarmer Group, Situgede Village, Sub District Bogor Barat, Bogor City. Activities are implemented by applyingtechnology recommendations and farmers fields. This research is to adaptation of New Superior Varieties Inpari30 and the recommendation of technology in Bogor City. The observed variables were: Plant Height (30, 60 and90 Day After Planting), yield component (number of grain fill per panicle and number of empty grain per panicleand productivity). The data were analyzed by t test. Analysis using SPSS version 20 for windows. The resultsshowed that Jajar Legowo Super Technology using New Superior Varieties Inpari 30 achieved productivity of7,60 t ha-1.Key words: New Superior Variety, Jajar legowo super

The modern world popularity of the nai — a traditional Romanian instrument — has identified interest in writing this article. This problematic constitutes the circle of our research interest as a doctoral candidate, but also as a concert performer, a graduate of the Academy of Music, Theater and Fine Arts. One of the most interesting aspects of the study of nai is its technical improvement since 60s of the 20th century, which led to the acquisition of a number of new, innovative skills and performance skills. In this article we have identified some pages of the modern history of the manufacture of this ancient instrument associated with these processes.

<p><em>Abstrak -</em><strong> </strong><strong>Produksi padi di Indonesia setiap tahun mengalami peningkatan, namun peningkatan ini belum mampu memenuhi kebutuhan nasional sehingga impor masih harus dilakukan. Salah satu masalah dalam produksi beras adalah penggunaan pupuk berlebih yang tidak hanya meningkatkan biaya produksi, namun juga merusak kondisi tanah. Aplikasi bakteri tanah sebagai Plant <em>Growth Promoting Rhizobacteria</em> (PGPR) dapat menjadi salah satu solusi terhadap masalah ini. Penelitian ini bertujuan untuk mengisolasi bakteri tanah dari 3 lokasi sawah daerah Bekasi, membandingkan keberadaan total bakteri pada ketiga lokasi tersebut,  dan melakukan karakterisasi isolat berdasarkan karakter yang dapat memicu pertumbuhan tanaman. Dari ketiga lokasi, diperoleh total 59 isolat dan 5 diantaranya berpotensi sebagai PGPR karena kemampuan fiksasi Nitrogen, melarutkan Fosfat, katalase positif, dan motil. Dari ketiga lokasi pengambilan sampel, BK1 memiliki jumlah total bakteri terendah karena aplikasi pemupukan dan pestisida berlebih yang ditandai tingginya kadar P total, serta tingginya residu klorpirifos, karbofuran, dan paration. Kondisi fisik tanah BK1 juga didominasi partikel liat yang menyebabkan tanah menjadi lebih padat. Peningkatan jumlah penggunaan pupuk tidak selalu diikuti peningkatan produktivitas tanaman.</strong></p><p> </p><p><strong><em>Kata Kunci</em></strong><strong><em> </em></strong>- <em>Bakteri tanah, Rhizosfer sawah, PGPR, Pupuk Hayati</em></p><p><strong> </strong></p><p><em>Abstract</em><strong> - </strong><strong>Rice production in Indonesia has increased annually, but this increase has not reached national demand,so imports still done. </strong><strong>One of the problems in rice production is the use of excessive fertilizers that not only increase production costs, but also decreased the soil conditions. The application of soil bacteria as Plant Growth Promoting Rhizobacteria (PGPR) can be the one solution to face this problem. The objective of this study was isolate soil bacteria from 3 locations of rice field in Bekasi, compare the total bacteria in the three locations, and characterize isolates based on the character that can promote plant growth. From three locations, a total of 59 isolates were obtained and 5 of them were potential as a PGPRs due to its Nitrogen fixation activity, Phosphate solubilization, positive catalase, and motility. From three sampling sites, BK1 has the lowest TPC value because of excessive  fertilizers and pesticides application which indicated by high total P levels, and also high chlorpyrifos, carbofuran and paration residues. The physical condition of BK1 soil is also dominated by clay particles which causes the soil more solid. Increasing of fertilizer application is not always followed by increased plant productivity.</strong></p><p><strong> </strong></p><p><strong><em>Keywords</em></strong> - <em>Biofertilizer, PGPR, Rice field rhizosphere, Soil Bacteria</em></p>
