PERTUMBUHAN TANAMAN SAWI HIJAU (BRASSICA RAPA VAR. PARACHINENSIS) AKIBAT PERLAKUAN LOGAM BERAT KADMIUM (CD)
ABSTRACT: The use of chemical
fertilizers and pesticides in agriculture in a continuous and excessive manner
can cause damage to the soil, one of which is the increase of the cadmium (Cd)
content. The increased level of Cd will have an effect on plant growth. This
research aims to find out the growth of mustard greens due to the treatment of
heavy metal (Cd) and to determine the concentration of Cd absorbed by plants.
The research was carried out from March to May 2015 in the Biology Laboratory
of the Faculty of Matematics and Naturan Sciences, of Tanjungpura University
Pontianak, and the Cd analysis was conducted in the Laboratory of Agricultural
Product Technology of the Faculty of Agriculture of Tanjungpura University. The
eksperimental design used was the Completely Randomized Design (CRD) which
consisted of 4 treatments and 3 repetitions, i.e. 0 ppm, 50 ppm, 100 ppm and
150 ppm. Research findings showed that the addition of cadmium reduces the
number of leaves, leaf area, fresh weight, dry weight and chlorophyll content
in the plant. The higher the concentration of Cd given to the plant, the higher
the concentration of Cd absorbed by green cabbage.The highest concentration of
Cd absorbed by green cabbage was 0,220 ppm at a treatment concentration of 150
ppm.
