Analisis Kandungan Timbal (Pb) pada Daun Tamarindus indica dan Samanea saman di Kecamatan Garum Kabupaten Blitar
Abstract: The
increasing number of
motorcycle will increase
the air polution.
For about 2900
motorcycles have increased in
Blitar. Such the negative impact of the lead (Pb) was put out by vehicle’s gas
emission toward human health, it needs an action to reduce Pb from the air, by
utilizing the plants which can absorb Pb. The purposes of
this research are to analyze
the differences of the Pb
contents on the
Samanea saman and Tamarindus indica leaves at the street of
Pojok, Sumberdiren, Bence, and Slorok and make the correlations between traffic
jam and the number of stomata due to the content of Pb.This research was
located in Garum Blitar on May 2015. The researcher measured the lead content
in sample by using AAS (Atomic Absorption Spectrophotometry) through camouflage
method. The calculation of the traffic jam used the handtaly couter. Mean while
the number of stomata’s calculation was done directly by using a microscope
binokuler Olympus CX21LED.The result showed that the content of Pb in Samanea
saman leaves in Pojok, Sumberdiren, Bence, and Slorok were 3,24-0,76 ppm and
the lead content on the Tamarindus indica leaves were 0,73-0,69 ppm. In
conclusion the researcher find that much more lead were found in Samanea saman
leaves. Based on the correlation test there is strong correlation in the number
of pb with traffic jam and the number of stomata.
