dc.description.abstract |
A living environment is said to be polluted if there are changes in the environmental order so that it
is not the same as the original form. If the environment is polluted at a higher level, it will kill more
than the types of organisms that live normally in the environmental order. Heavy metal pollution
increases with industry development. One of the efforts to keep the life order from being polluted or
to become damaged is the existence of a waste management system or the use of the waste to be
used as a more useful product. For example in this study is the utilization of melinjo fruit peel
waste.
This study uses an experimental method with Atomic Absorption Spectrophotometer. Analyzed by
two-way ANNOVA test statistics without interaction.
Pb metal content that can be absorbed by melinjo fruit peel powder is 13.81 ppm for 160 mesh
concentration of 50 ppm; 6.45 ppm for mesh 160 concentration of 75 ppm; 0.89 ppm for mesh 160
concentration of 100 ppm; 32.26 ppm for 50 mesh concentration of 50 ppm; 76.91 ppm for mesh 50
concentration of 75 ppm; 88.87 ppm for 50 mesh concentration of 100 ppm. ANNOVA analysis
obtained the value of Fcount (mesh) = 7.96 and Ftable = 98.49; Fcount (concentration) = 0.42
and Ftable = 99.00; Ho is rejected, Ha is accepted. It was concluded that there was a significant
difference between mesh variation and concentration on metal absorption by melinjo fruit peel
powder. |
