PENGARUH LOGAM BERAT Cd, Pb TERHADAP PERUBAHAN WARNA BATANG DAN DAUN SAYURAN

Edit
Abstract: Cd,  Pb  heavy  metal  absorption  in  aquatic  vegetables:  Genjer  (Limnocharis  flava), Kangkung  air  (Ipomoea  aquatica  Forsk)  dan  Selada  air  (Nasturtium  officinale  R.  Br), studied  to  see  the  relationship  with  green  figure  scale.  The  research  objective  was  to identify the accumulated Cd, Pb in the consumed organ vegetable, and their impacts to the levels  of  green  figure  scale.  The  research  was  undertaken  by  planting  three  kinds  of  the aquatic vegetables to the contaminated pure Cd,pure Pb media, mixture of Cd and Pb with factorial  randomized  block  design.  Data  were  analyzed  by  factorial  One-Way  Anova  and further  test  of  Duncan  and  HSD  to  see  the  difference  of  Cd,  Pb  and  green  figure  scale, regression  and  correlation  to  know  the  contribution  of  Cd,  Pb  in  influencing  the  green figure  scale.  Variety  of  vegetables,  media,  organ,  and  the  interaction  influences  the accumulation of Cd, Pb and level of green figure scale. There is a relationship between Cd, Pb  metal  accumulation  to  the  level  of    green  figure  scale  of  the  aquatic  vegetables,  with negative correlation that Cd, Pb decreased the vegetable green figure scale.
Keywords: the influence of Cd, Pb; aquatic vegetables; green figure scale
