PENGARUH PENAMBAHAN PUPUK CAIR KULIT PISANG KEPOK (Musa paradisiaca formatypica) TERHADAP PERTUMBUHAN TANAMAN PAKCOY (Brassica rapa L.) BUDIDAYA HIDROPONIK SEBAGAI SUMBER BELAJAR BIOLOGI

Pakcoy (Brassica rapa L.) is a horticultural product that is popular with the public. The
production of pakcoy (Brassica rapa L.) vegetables is constrained by the limited space
or medium to grow. The limitation of soil media as a growing medium for plants can be
anticipated by using hydroponic cultivation methods. However, the high price of AB
Mix fertilizer is a problem because it increases production costs. An alternative
innovation that can be done is by providing organic fertilizer, one of which is liquid
fertilizer of banana peel (Musa paradisiaca formatypica). The purpose of this study is
to find out the effect of giving liquid fertilizers of banana peel (Musa paradisiaca
formatypica) in increasing the growth of pakcoy plants (Brassica rapa L.). This study is
an experimental study with the post test design of a control group that uses 5 treatments
by repeating 5 times, where negative control treatments use water, positive control
treatments use AB Mix, and negative control treatments use water. and 3 treatment
groups using liquid organic fertilizer banana peel with concentrations of 30ml, 40ml and
50ml. The results of the data analysis after the One-Way Anova test showed that there
was a significant effect with the results on the number of leaves, plant height, and plant
weight obtained a value of < 0.001. Based on these results, it can be concluded that the
liquid organic fertilizer of banana peel (Musa paradisiaca formatypica) on the number
of leaves, plant height, and plant weight has an effect on the growth of the pakcoy plant
(Brassica rapa L.).
