Abstract

Hydroponic cultivation is an alternative in utilizing narrow land or land that is not suitable for agriculture. What has an important role in hydroponic cultivation is nutrition, where these nutrients are dissolved in water before being flowed into the hydroponic device. The provision of different types of nutrient solutions and different water concentrations greatly affects the productivity of hydroponic plants. This research was conducted from September to November 2019, at the Sidondo Agricultural Technology Research and Study Installation (IP2TP). The purpose of this study was to determine the concentration of raw water and concentration of AB Mix solution which is good for plant growth in hydroponics. The method in this study used a factorial randomized block design (RAKF) consisting of two factors. The first factor is the type of nutrient solution (Agromax and Hidro J) and the second factor is the concentration of Total Dissolve Solid in raw water (20 ppm and 200 ppm). The type of vegetable used for hydroponic cultivation is water spinach. Each treatment was repeated 3 times. Based on the results of the study, it was found that giving Agromax nutritional solution using a concentration of Total Dissolve Solid raw water 20 ppm gave the best growth results when compared to other treatments, on each yield parameter of kale including plant height, number of leaves, stem diameter, leaf area, root length, root weight, leaf weight, and stem weight.
