- Hydroponic is a known technique in agriculture, using water instead of soil as growingmedia, where specific fertilizer were constinously added. Generally, chemical fertilizer wereused in hydrophonic system, i.e. AB mix fertilizer, a combination of several fertilizer, whichcertainly costly. This research aim to find alternative fertilizer for hydrophonic where growthof the plants/crops is maintained. Two possible fertilizer easily found nearby UNAI campuswere cow urine, and discarded parts of green vegetables. Fermentation of these urine andgreen compost were the main role to produce appropriate fertilizer, known as bokashi.Pakcoy (Brassica rapa L. var. Chinensis) seedling were used from its ready for planting time(approx. 4 days) in rockwool. Hydroponics system utilizing Deep Flow Technique (DFT), Ashape model. Data of pakcoy growth including height of the plants, leaves width and rootlength were measured every week up to 5 weeks. Data were analyzed using Analysis ofVariance (ANOVA) and continued with Duncan Multiple Range Test. The result showedthat, on plants height, each fertilizer was differing each other, where AB mix is higher withaverage 22.71 cm, followed by green bokashi 18.74 cm, and cow urine bokashi 16.38 cm. Onleaves width, AB mix is greater with average 9.22 cm, followed by green bokashi 8.03 cmand cow urine bokashi 7.00 cm. Analysis on root length, AB mix is higher with average49.76 cm, followed with green bokashi 21.33 cm, and cow urine bokashi 21.21 cm. Thisresearch concludes that green bokashi and cow urine bokashi could be use as alternativefertilizer in hydroponics system, although AB mix gives higher growth.
