"This study was conducted to determine the influence of various types and doses of fertilizer in the mud media for the silkwon population abudance (tubifex sp). Fertilizer contain high nutrient elements are useful as food for silk worms so that they can grow on silkworms population in the mud medium. This study used 27 aquarium ,size 50 cm x 30 cm x 25 cm. This experiment using a completely randomized factorial design with nine treatments and three replicates. The treatment consist of two factors that the type and dose, includes: chiken manure with a dose of 20%,40% and 60%,with a dose of duck manure 20%,40% and 60% and cow dung with a dose of 20%,40% and 60%.Earthworm population data for 10 days after the study were analyzed by analysis of variance followed by the least significant difference test to determine differences among the treatments. Results from the study indicate that differences in type and dose fertilizer sludge influence on the media (P<0.05) in the population abudance of silk worm (tubifex sp) .Chiken manure fertilizer types and doses of 60% gave the best results with an average population abudance of 215 individuals."

"Polianthes tuberosa L. is a potential flowering plant to be developed in Jatinangor, but, the type of soil inJatinangor belongs to Fluventic Eutrudepts has a lower of pH, medium of available K and potential K. Newstrategy is needed to resolve these problems such as by adding the organic and an-organic fertilizer. This researchwas conducted to determine the effect of the combination organic fertilizer and NPK on soil reaction (pH),available K, Potential K, and fresh weight of tuberose (Polyanthes tuberose L.) on Fluventic Eutrudepts. Theresearch design used was Randomized Block Design (RBD) with ten treatments and three replications, consist of:without organic fertilizer + NPK (control); without organic fertilizer + recommended dosage of NPK;recommended dosage of organic fertilizer + without NPK; ½ recommended dosage of organic fertilizer + ½recommended dosage of NPK; ½ recommended dosage of organic fetilizer + recommended dosage of NPK;recommended dosage of organic fetilizer + ½ recommended dosage of NPK; without organic fertilizer + 1 ½recommended dosage of NPK; 1 ½ recommended dosage of organic fertilizer + without NPK; 1 ½ recommendeddosage of organic fertilizer + ½ recommended dosage of NPK; 1 ½ recommended dosage of organic fertilizer +recommended dosage of NPK. The results show that there were effect of soil reaction (pH), available P, potentialP, and fresh weight of tuberose from combination of organic fetilizer and NPK. Treatments of 1 ½ recommendeddosage of organic fertilizer + without NPK gives the best results of 148,6 g plant-1 with an increase 63,2%compared with no treatment.Sedap malam (Polianthes tuberosa L.) merupakan tanaman hias berbunga indah yang sangat potensialdikembangkam salah satunya di Jatinagor. Tanah di Jatinangor yang termasuk ke dalam sub group FluventicEutrudepts mempunyai reaksi tanah agak masam, K-potensial sedang, K-dd sedang, dan KTK rendah, sehinggaperlu dilakukan upaya untuk meningkatkannya yang salah satunya dengan pemupukan. Percobaan dilakukan untukmengetahui pengaruh pemberian kombinasi pupuk organik dan pupuk NPK terhadap K-potensial, K-dd, KTK danbobot segar tanaman sedap malam (Polyanthes tuberosa L.) pada Fluventic Eutrudepts. Rancangan percobaanyang digunakan adalah Rancangan Acak Kelompok (RAK) faktor tunggal dengan sepuluh perlakuan dan tigaulangan, yaitu terdiri dari : Tanpa pupuk organik + pupuk NPK (kontrol); Tanpa pupuk organik + dosis anjuranNPK; Dosis anjuran pupuk organik + tanpa pupuk NPK; ½ dosis anjuran pupuk organik + ½ dosis anjuran NPK;½ dosis anjuran pupuk organik + dosis anjuran NPK; Dosis anjuran pupuk organik + ½ dosis anjuran NPK; Tanpapupuk organik + 1 ½ dosis anjuran NPK; 1 ½ dosis anjuran pupuk organik + tanpa pupuk NPK; 1 ½ dosis anjuranpupuk organik + ½ dosis anjuran NPK; 1 ½ dosis anjuran pupuk organik + dosis anjuran NPK. Hasil penelitianmenunjukan terdapat pengaruh terhadap K-potensial, K-dd, KTK dan bobot segar tanaman sedap malam akibatpemberian kombinasi pupuk organik dan pupuk NPK. Perlakuan 1 ½ dosis anjuran pupuk organik + tanpa pupukNPK memberikan bobot segar tanaman sedap malam terbaik sebesar 148,6 g tanaman-1 dengan kenaikan bobotsegar 63,2% dibandingkan dengan tanpa perlakuan."

"ABSTRAKPenelitian ini bertujuan untuk upaya peningkatan produksi dan hasil budidaya tanaman bawang merah yangberwawasan lingkungan dengan pemanfaatan pupuk kandang sapi dan pengaturan jarak tanam. Penelitiandilaksanakan selama 8 bulan dari bulan Januari sampai dengan Agustus 2015.Penelitian dilakukan di lahan sawahBrebes, Kabupaten Brebes, jenis tanah alluvial dengan ketinggian tempat kurang lebih 50 m dpl. Penelitian inimerupakan percobaan faktorial 4 x 3 dengan rancangan lingkungan adalah rancangan acak kelompok. Faktorpertama adalah Jarak Tanam: J1 = 20 cm x 20 cm, J2 = 20 cm x 15 cm, J3 = 20 cm x 10 cm. Faktor yang keduaadalah takaran pupuk kandang sapi yaitu K0 = 0ton/ha, K1 = 10 ton/ha, K2 = 20 ton/ha, K3 = 30 ton/ha. Karakterpertumbuhan dan hasil bawang merah diamati pada penelitian ini. Data hasil pengamatan dianalisis dengan uji Funtuk mengetahui keragamannya dan apabila ada perbedaan nyata dilanjutkan dengan DMRT dengan tingkatkesalahan 5%. Hasil penelitian menunjukkan bahwa hasil umbi segar dan kering bawang merah per hektar tertinggidiperoleh pada tanaman dengan perlakuan jarak tanam 20 x 15 cm dengan hasil 20,56 t/ha (umbi segar) dan 18,63t/ha (umbi kering)."
