PENGARUH AERASI TERHADAP PERTUMBUHAN TANAMAN BABY KAILAN (Brassica oleraceae var. achepala) PADA TEKNOLOGI HIDROPONIK SISTEM TERAPUNG DI DALAM DAN DI LUAR GREENHOUSE

Edit
ABSTRACT: This research is aimed to find out the effects of aeration on baby kailan (Brassica oleraceae var. Achepala ) in floating system hidroponic technology inside and outside the greenhouse.  This research used a factorial in a split plot design with 2 factors, namely factor I (weation) and Factor II (aeration).  The first factor had two levels, inside  (N0) and  outside (N1)  greenhouse.  The  second factor  consisted of  3 levels;  mechanical aeration  (A1), hanging  styrofoam  (A2)  and  floating  styrofoam  (A3);  resulting  in  six  treatment  combinations  with  three replications.  The data was analyzed using ANOVA (analysis of variance) at 5 % significant level and folowed by LSD. The results showed that the inside and otsutside greenhouse significantly affected growth and yield. The use of aeration outside the greenhouse had shown maximal production.  The hanging styrofoam system (A2) inside the  greenhouse  showed  the  lowest  production  cost  (fertilizer  and  electricity.    None  of  the  environment  and nutrition  parameters  (EC,  DO  and  pH)  was  significantly  different  during  the  research,  implying  that  the environment and nutrion solution were homogeneous and did not affect the plant growth.
