Abstract

This research is aimed to find out the effects of aeration on baby kailan (Brassica oleraceae var. Achepala ) in
floating systemhidroponic 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 shownmaximal production. The hanging styrofoamsystem (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 solutionwere homogeneous and did not affect the plant growth.
