<![CDATA[Pakchoy adalah salah satu sayuran daun yang banyak mengandung berbagai mineral dan vitamin, kayaklorofil (antioksidan).Tujuan penelitian adalah mengetahui pengaruh pupuk organik (bokashi) berbasis biomassaAzolla microphylla(Am) dan Lemna polyrhiza (Lp) terhadap: 1) serapan unsur N tanaman pakchoy, 2)pertumbuhan dan produksi tanaman pakchoy,dan 3) porositas Inseptisols. Penelitian ini adalah percobaan potyang dilaksanakan di rumah plastik Fakultas Pertanian Universitas Jenderal Soedirman, Purwokerto padaketinggian 110m dpl. Penelitian dilaksanakan pada Oktober 2012 sampai Februari 2013.Rancangan yangdigunakan adalah Rancangan Acak Kelompok Lengkap dengan 5 perlakuan dan 4 ulangan. Perlakuan pupukorganik bokashi meliputi : kontrol; 60% biomassa Azolla microphylla + 40% kompos kotoran sapi; 60%biomassa Lemna polyrhiza + 40% kompos kotoran sapi; 100% kompos kotoran sapi; pupuk majemuk NPK.Variabel yang diamati adalah serapan N tanaman,, pertumbuhan, dan hasil tanaman pakchoy, serta BJI, BJP, danporositas Inseltisols. Hasil penelitian menunjukanpemberian pupuk bokashi berbasis Am dan Lp masing-masingmampu: (1)meningkatkanserapan N tanaman 669% dan 512% terhadapkontrol tanpa pupuk, (2) meningkatkanhasil sebesar 263,89 % (hasil 15,72 t/ha) dan 267,82 % (hasil 15,89 t/ha) terhadap kontrol tanpa pupuk, dan (3)menurunkan nilai BJI Inseptisols sebesar 16% dan 23%, dan menurunkan porositas Inseptisols sebesar 23% dan18%.Kata kunci: Azolla microphylla, Lemna polyrhiza, pupuk kandang sapi, pakchoy, pertanian organikABSTRACTPakchoy is one of vegetable contains lot of minerals and vitamins as well as rich in chlorophyll that canserve as antioxidants.This research purpose were to know influence of Bokashi Azolla microphylla (Am) andLemna polyrhiza (Lp) biomass-based on : 1) plant N uptake, 2) growth and yield of pakchoy, and 3)Inceptisolporosity. This research was used polybag to cultivate the pakchoy during October 2012 until February 2013 inscreen house Jenderal Soedirman University, Purwokerto at 110m above sea level. This research used RCBD(Randomized Complete Block Design) with 5 treatments and 4 replications. The treatment tested were: control;60% Am biomass + 40% cattle manure; 60% Lp biomass + 40% cattle manure; 100% cattle manure; NPKfertilizer. Variabel observed plant N uptake, growth and yield of pakchoy, Bulk Density (BD), Particle Density(PD), and porosityof Inceptisols. The result showed that bokashi based of both of Am and Lp biomass, compareto no-fertilizer, it had respectively ability to: (1) increase plant N uptake by 669% and 512%, (2) increase theyield of pakchoy by 263,89 % (yield15,72 t/ha) and 267,82 % (yield15,89 t/ha), and (3) decrease Inseptisols’BDby16% and 23%, anddecrease Inseptisols’ porosity by 23% and 18%.Keywords : Azolla microphylla, Lemna polyrhiza, cattle manure, pakchoy, organic agriculture]]>
