Aktivitas Enzim Peroksidase dan Kadar Klorofil pada Daun Angsana (Pterocarpus indicus) sebagai Peneduh Jalan yang terpapar Timbal
Abstrak: One of emissions in
the air that’s harmful to human health
is lead ( Pb ). The negative effects caused
by lead and then required
solutions for reducing the metal, its called phytoremediation. The Plant which
acts as an agent of phytoremediation is Angsana (Pterocarpus indicus Willd.).
Research to find out the lead content in Angsana’s leaf at four locations,
knowing the influence of exposure to lead against the activity of an enzyme
peroxydases and chlorophyll content in the Angsana’s leaf. The location for
collection of samples conducted in four
location at Purwokerto (1) H.R Bunyamin, (2) Ovis Isdiman, (3) Gerilya,
and (4) Dr. Soeharso. A method of the sample used purposive sampling. Sample were analysed using wet digestion method, then were
analysed using Atomic Absorbance Spectrofotometer (AAS). The activity of
peroxydases and levels of chlorophyll were analysed using spectrophotometer Uv
Vis. Result showed that the lead content in Angsana’s leaf is 0,1
– 0, 25 mg/L, the activity of peroxidases is
600- 1250 unit/g and chlorophyll content is 9,0- 21,0 mg/L. The conclusion was no
relations about chlorophyll content with levels of lead content and the relations about activity
of enzymes peroxydases and lead content is low . Content of lead on Angsana’s leaf of research has been done do not reach 1000
mg/L.
