The method used in this study is a survey method with the case in Kampung Rawa Ants RT / RW 04/12 Margahayu Village, East Bekasi. A total of 30 farmers caisim as respondents. The analysis model used is the Cobb-Douglas models, followed by analysis of the elasticity of production factors. The results showed that (a) chicken manure significantly affect yield while seed, urea fertilizer , KCl fertilizer, NPK fertilizer, TSP fertilizers and pesticides have no effect, (b) the use of factors of production is not efficient KCl fertilizer, chicken manure fertilizer and pesticides, while seeds, urea fertilizers , NPK and TSP fertilizer inefficient.

Kebutuhan pupuk setiap musim tanam semakin meningkat sehingga terjadi kelangkaan pupuk pada beberapa sentra produksi pertanian. Kelangkaan pupuk terutama yang bersubsidi ini terjadi karena perbedaan perhitungan jumlah kebutuhan pupuk antara petani dengan Deptan, adanya pemborosan ditingkat petani karena belum sesuainya dosis, waktu pemberian dan cara pemupukan untuk setiap lokasi, jenis dan fase pertumbuhan tanaman. Selain itu, penyebab terjadi kelangkaan pupuk karena adanya kenakalan dan kemacetan dalam jalur distribusi pupuk bersubsidi dan terjadi penggunaan pupuk bersubsidi untuk industri dan bukan langsung didistribusikan ke petani. Upaya untuk mengatasi kelangkaan pupuk antara lain adalah pengelolaan hara spesifik lokasi, pemanfaatan bahan organik, dan penggunaan pupuk hayati. Selain itu juga dilakukan upaya perbaikan budaya dan karakter semua pelaku yang berhubungan dengan pupuk. Kata Kunci : Pupuk, pupuk organi...

Penyebab banjir di Jakarta adalah (1) peristiwa alam (dinamis), (2) kondisi fisik (statis) dan (3) kegiatan manusia (dinamis). Interaksi ketiga faktor tersebut yang dapat memunculkan banjir apabila terdapat ketidakseimbangan ekologis dan seringkali dipicu oleh kegiatan manusia yang terlalu mengeksploitasi sumberdaya alam. Solusi untuk mengendalikan banjir di Jakarta adalah (1) Peningkatan kapasitas saluran drainase; (2) Mempertahankan dan menghidupkan situ-situ yang masih ada; (3) Pembuatan sumur resapan; (4) Rehabilitasi Daerah Tangkapan Air; (5) Membuat hutan mangrove di sepanjang pantai utara; dan (6) Meningkatkan infiltrasi air di daerah hulu DAS Ciliwung, yakni daerah atas dari Jakarta yaitu dengan cara menggunakan lahan sesuai dengan kaidah konservasi tanah dan air (7) semakin menyadarkan penduduk akan pentingnya pe...

The process of nitrogen fixation by non-symbiotic bacteria requires several conditions : (1) the enzyme nitrogense, (2) the availability of energy resources in the form of ATP, (3) the potential lowering of the electron source, (4) a system of protection of nitrogenase enzyme from inactivation by oxygen, and (5) rapid transfer of nitrogen to prevent the inhibition of the enzyme nitrogenase. The result of nitrogen fixation by non-symbiotic aerobic bacteria was higher than the non-symbiotic fixation by anaerobic bacteria. The mechanism of protection of nitrogenase from oxygen by non-symbiotic aerobic bacteria are consuming excessive O 2 for respiration and Azotobacter which have a capsule mucus (EPS) a thick helping protect the enzyme nitrogenase from O 2 . For anaerobic bacteria oxygen is not a problem because the environmental of bacteria are low oxygen. Keyword : Nitrogen fixation, non-symbiotic bacteria, ni...

Nitrogen is mostly sourced from inorganic fertilizer (urea). Efficiency of urea is low and negative impact on the environment. Utilization of biological nitrogen fixation technology in paddy fields will reduce the use of urea as a source of N, to prevent the decrease soil organic matter and reduce pollution to the environment. Utilization Azospirilum and Azotobacter either single or together have been able to increase yield and N uptake in rice paddies. Use of Azotobacter and Azospirillum inoculant must be balanced with the provision of organic matter and environmental control, especially the supply of oxygen to the success of these microbes in a of these microbes in nitrogen fixation and production of growth regulators.

Quality seeds obtained through a series of seed technology activities starting from seed production, seed processing, seed testing, certification of seeds to seed storage. Storage of seeds is one of the soy harvest handling of the whole technology is important to maintain seed quality. The main objective of seed storage is to maintain the viability of the seeds along as possible and to maintain the fsiologis quality of seeds during the period storage by inhibiting the deterioration speed of the seed. Factors that influence the viability of seeds during storage is divided into internal and external factors. Internal factors include genetic trait, the power to grow and Vigor, skin conditions and initial seed moisture content. External factors such as packaging of seeds, gas composition, temperature and humidity save space. Keywords : soybean seed, seed deterioration, viability, seed storage

Berdasarkan luas panen dan produktivitasnya tanaman pangan unggulan di Kabupaten Bekasi adalah padi, ubi kayu, dan jagung. Berdasarkan R/C komoditas pangan unggulan di Kabupaten Bekasi masih efisien. Hal ini ditunjukkan oleh nilai R/C padi 2.17, R/C jagung 1.74, dan R/C ubi kayu 2.75. Penggunaan faktor produksi pupuk dan pestisida untuk komoditas padi sudah tidak efisien tetapi masih berada dalam kondisi icreasing return to scale, sedangkan untuk komoditas ubi kayu penggunaan faktor produksi biit dan biaya panen sudah tidak efisien, dan komoditas ini sudah berada pada posisi decreasing return to scale. Untuk komoditas jagung penggunaan pestisida dan benih sudah tidak efisien lagi. Kata Kunci : Tanaman pangan unggulan, R/C, efisiensi, dan skala usaha

Remediation of health and fertility of paddy fields can be done by utilizing the integrated biofertilizer with straw compost. This study aims to get a diluent of biofertilizer and available around the farmers as well as to test the ability of biofertilizers in increasing rice yields with two cropping systems (IPAT and Legowo). IPAT application of cropping systems on biofertilizer application with three a diluent (husk, compost and manure) gives the average number of panicles per hill and higher grain yield, respectively for 23,23% and 11,3% compared to treatment legowo cropping systems. Diluents rational biofertilizer is manure and compost, good for cropping systems and Legowo IPAT. The highest grain yield occurred at doses of urea fertilizer application of 200 kg ha -1 , 2 ton ha -1 straw compost and 400 g ha -1 biofertilizer, planti...
