Tujuan penelitian ini untuk mengetahui respon pertumbuhan dan produksi tanaman kedelai <em>(Glicyne </em><em>max L.)</em> terhadap pemberian kompos limbah Brassica dan pupuk hayati Riyansigrow. Penelitian dilaksanakan di kebun percobaan Fakultas Pertanian Universitas Medan Area yang berlokasi di jalan kolam No. 1 Medan Estate, Kecamatan  Percut Sei Tuan. Penelitian ini dilaksanakan mulai dari bulan Mei  2014, mengunakan Rancangan Acak Kelompok (RAK) faktorial, dengan dua ulangan, 16 kombinasi. Faktor pertama adalah Pupuk kompos limbah Brassica yaitu K0 = tanpa kompos, K1 = diberi kompos 2 ton/ha, K2 = diberi kompos 4 ton/ha, dan K3 = diberi kompos 6 ton/ha. Faktor kedua adalah konsentrasi pupuk hayati Riyansigrow yaitu H0 = tanpa pupuk hayati,  H1 = diberi pupuk hayati 2,5 kg/ha, H2 = diberi pupuk hayati 5 kg /ha dan H3 = diberi pupuk hayati 7,5 kg/ha. Hasil penelitian  menunjukan bahwa pengaruh kombinasi kompos limbah Brassica dan pupuk hayati Riyansigrow mampu meningkatkan pertumbuhan (kecuali tinggi tanaman) dan produksi tanaman kedelai, dibandingkan dengan penggunaan pupuk anorganik. Secara umum penelitian ini menunjukan bahwa penambahan kompos limbah Brassica dan pupuk hayati Riyansigrow dapat meningkatkan pertumbuhan dan produksi tanaman kedelai dengan biaya produksi lebih ekonomis.

The purpose of this study was to obtain data on the ability of cabbage compost (Brassicaceae) and banana weevil liquid organic fertilizer on the growth and production of long bean plants (Vigna Sinensis L.). The method used in this study is a randomized block design (RBD) in factorial, with 2 (two) treatment factors, Namely: 1) Factors Cabbage Compost Fertilizer (K); 2) Faktors liquid organic fertilizer banana weevil (P), each treatment was repeated two (2) times so that there are 32 experimental plots. Each experimental plot consisted of 9 plants with 4 plant samples. The parameters were observed in this study consisted of stem diameter, number of pods per sample plant, pod length per sample plant, pod weight per sample plant, production per plot; From the research has been carried out can be concluded as follows: 1) Provision of POC banana weevil has no real effect on stem diameter, number of pods per sample plant, pod length per sample plant, pod weight per sample plant, production per plot; 2) The administration of cabbage compost has a significant effect on stem diameter, number of pods per sample plant and production per plot, but has no real effect on pod length per sample plant and pod weight per sample plant; 3) The combination of the two treatment factors has no real effect on stem diameter, number of pods per sample plant, pod length per sample plant, pod weight per sample plant, production per plot

AbstrakPenelitian ini bertujuan untuk mengetahui apakah pemberian pupuk Kandang Sapi dan Super Bokasi AOS Amino memberikan respon yang baik terhadap pertumbuhan dan produksi bawang merah. Penelitian dilakukan di kebun percobaan Fakultas Pertanian Universitas Medan Area yang berlokasi di jalan Kolam No.1 Medan Estate, Kecamatan Percut Sei Tuan. Penelitian ini di laksanakan mulai bulan juni sampai dengan Agustus 2014, mengunakan Rancangan Acak Kelompok (RAK) Faktorial, dengan dua ulangan, 16 kombinasi sehingga didapat 32 plot tanaman dari seluruh kombinasi dan ulangan. Faktor pertama yang diuji adalah pupuk kandang sapi yaitu K0 = tanpa pupuk kandang sapi, K1 = mengunakan pupuk dengan dosis 200 gram /plot, K2 = mengunakan pupuk kandang sapi 400 gram/plot, K3= mengunakan pupuk kandang sapi dengan dosis 600 gram /plot. Faktor kedua yang diuji adalah Super Bokasi AOS Amino yaitu A0 = Tanpa mengunakan AOS Amino, A1= mengunakan AOS Amino (1,875 ml/l air), A2 = mengunakan AOS Amino (3,75 ml/l air), A3= mengunakan AOS Amino (5,625 ml/l air). Hasil penelitian menunjukan bahwa pemberian pupuk kandang sapi dan AOS Amino perpengaruh nyata pada pengamatan bobot basah perplot dengan nilai F-hitung 4,13 pada perlakuan AOS Amino dan tidak perpengaruh nyata pada parameter lainya, dan hasil rata bobot umbi perplot menunjukan hasil yang tinggi pada perlakuan A3 (5,625 ml/l air). AbstractThis study aims to determine whether the application of Kandang Sapi fertilizer and Super Bokasi AOS Amino provide a good response to the growth and production of shallots. The research was conducted in experimental garden of Agriculture Faculty of University of Medan Area, located at Medan No.1 Pond Street, Percut Sei Tuan District. This research was conducted from June to August 2014, using Factorial Randomized Block Design (RAK), with two replications, 16 combinations so that 32 plots of plants from all combinations and replications were obtained. The first factor tested was cow manure that is K0 = without cow manure, K1 = using fertilizer with dose 200 gram / plot, K2 = using cow manure 400 gram / plot, K3 = using cow dung manure with dose 600 gram / plot . The second factor tested is Super Bokasi AOS Amino that is A0 = Without using AOS Amino, A1 = using AOS Amino (1,875 ml / l water), A2 = using AOS Amino (3.75 ml / l water), A3 = using AOS Amino (5,625 ml / l of water). The results showed that the application of cow manure and AOS Amino significant effect on the observation of wet weight of the plot with F-count value of 4.13 on the Amino AOS treatment and no significant effect on other parameters, and the average yield of tuber bulbs showed a high result on the treatment A3 (5,625 ml / l water).

The Response Of Liquid Waste Utilization Of Palm Oil On Growth And Production Plant Of Kailan (Brassica Oleraceae L.). Under the guidance of  Ir. Gusmeizal, MP as the commission chairman of counselor and Ir. Ellen L. Panggabean, MP as the commission member of counselor.  This research was conducted at the experimental garden of Agriculture Faculty University of Medan Area, located on Jl. PBSI Medan Estate. This research was conducted began in April 2016 until June 2016. The purpose of this research was to determine the response of liquid waste utilization of palm oil on growth and production plant of kailan. This research was conducted by using Randomized Block Design (RBD) non factorial which consists of 4 levels of treatment are: L0 = Control (NPK 20 g/plot),  L1 = 1 l/plot,  L2 = 2 l/plot,  L3 = 3 l/plot. Parameters observed were height of plants, leaf number, stem diameter, fresh weight of harvest by plot, fresh weight of harvest by sample, fresh weight of sell by plot, fresh weight of sell by sample. The results of research showed that utilization of liquid waste of palm oil did not show significantly different results in all parameters of observation, but the liquid fertilizer from palm oil waste is able to compensate for the growth and production plant of kailan (Brassica oleracea L.) that fertilized with NPK.

Tujuan penelitian ini untuk mengetahui pengaruh pupuk kandang sapi dan Super Bokasi AOS Amino memberikan pengaruh yang baik terhadap pertumbuhan dan produksi kacang hijau. Penelitian dilakukan di kebun percobaan Fakultas Pertanian Universitas Medan Area yang berlokasi di jalan Kolam No.1 Medan Estate. Penelitian ini di laksanakan bulan Mei sampai bulan Juli 2015, menggunakan Rancangan Acak Kelompok (RAK) Faktorial, dengan dua ulangan, 16 kombinasi. Faktor pertama yaitu pupuk kandang sapi yaitu S0 = tanpa pupuk kandang sapi, S1 =  pupuk kandang pada dosis 2,25 kg per plot, S2 = pupuk kandang sapi pada dosis 4,5 kg per plot, S3= pupuk kandang sapi pada dosis 6,75 kg per plot. Faktor kedua adalah Super Bokasi AOS Amino yaitu A0 = Tanpa pemberian AOS Amino, A1= AOS Amino pada konsentrasi 0,375 %, A2 =  AOS Amino pada konsentrasi 0,75 %, A3= AOS Amino pada konsentrasi 1,13 %. Hasil  penelitian menunjukan bahwa perlakuan dosis pupuk kandang sapi ( S ) nyata meningkatkan tinggi tanaman, jumlah daun, dan berat basah per 100 biji tanaman sampel kacang hijau (Vigna radiata L.) varietas vima-1.Perlakuan konsentrasi pupuk super bokasi AOS Amino (A) nyata meningkatkan tinggi tanaman dan jumlah daun kacang hijau (Vigna radiata L.) varietas vima-1. Serta perlakuan dosis pupuk kandang sapi dan konsentrasi pupuk super bokasi AOS Amino (SA) nyata meningkatkan tinggi tanaman dan jumlah daun kacang hijau (Vigna radiata L.) varietas vima-1.
