PENGARUH KONSENTRASI NUTRISI AB-MIX TERHADAP PERTUMBUHAN TANAMAN PAKCOY (Brassica rapaL.) DENGAN MEDIA TANAM HIDROPONIK SISTEM NUTRIENT FILM TECHNIQUE (NFT) DALAM UPAYA PEMBUATAN BROSUR BAGI MASYARAKAT
Keywords:Hydroponics, NFT, AB-Mix Liquid Fertilizer, Pakcoy.
AB-Mix liquid fertilizer contains macro and micro nutrients which are the nutrients needed to support plant growth and yield. The purpose of this study was to determine the effect of AB Mix nutrition (concentrations of 3 ml/L, 7 ml/L, and 11 ml/L) on the growth of pakcoy plants (Brassica rafa L.) using the Hydroponic System Nutrient Film Technique (NFT). The research was carried out at the UNDIKMA Biology Laboratory. Randomized block design (RBD) method with 4 treatments and 6 replications was used in this study. Data analysis from this study used one way ANOVA analysis, with this analysis used to analyze the growth of Pakcoy (Brassica rapa L.) plants, at a significant level of 5% this was done to obtain valid data, if there is a significant to very significant effect then followed by the least significant difference (LSD) test. Based on the results of the research and discussion, it can be concluded that the concentration of AB-Mix liquid fertilizer has a significant effect on the growth of pakcoy plants on the parameters of plant height, number of leaves, and leaf width. The best and most optimal concentration for plant height was found in treatment P2 with a concentration of 7 ml/L, then the parameter for the number of leaves was in treatment P3 with a concentration of 11 ml/L and in the parameter of leaf width there was in treatment P1 with a concentration of 3 ml/L L. The results of the analysis of the qualifications of the brochure assessment which were compiled and validated based on the results of the validators in the field of language experts, materials and appearance were 86.66% and were declared very good.
