Abstract:
Heavy metals in aquatic environments have been known to cause some damage to aquatic
life. Pb metal is found in waste that pollute the waters. In modern life today many people
have a habit of disposing of garbage disembarang place. Utilization of jengkol skin
powder which is organic waste scattered in the traditional market can be used for the
processing of liquid waste containing Pb metal.
This research used experimental method by using Atomic Absorption Spectrophotometer
which then analyzed statistically using two way ANOVA test without interaction.
From the results of the study found that jengkol skin powder can absorb Pb metal that
exists in the liquid waste in the surrounding environment. After statistical test with twoway
ANOVA test without interaction, Pb metal absorption by jengkol skin powder with pH
and mass ratio, then got value of F count (mass) = 3,763 and F value table = 98,50 while
F value count (pH) = 0,812 with value F table = 99,00 with result Ha rejected and H0
accepted. From the results of this study can be concluded that there is no significant
difference in the absorption of Pb logan using jengkol skin powder in pH and mass
variations.
