Abstract
Jatibarang Landfill, Semarang, produces leachate, which has the potential to pollute the environment because it contains heavy metal compounds, such as Fe (II), Pb (II) and Cr (VI) compounds. To prevent leachate spread, a layer that can be used as an adsorbent is needed, one of which is a composite material consisting of construction waste, bentonite and lime. The objectives of this study include analyzing the migration of Fe (II), Pb (II) and Cr (VI) on the liner with variations in the composition of construction waste, bentonite and lime. Testing the concentrations of Fe (II), Pb (II) and Cr (VI) was carried out for leachate before entering the reactor and when the reactor passed out of the reactor outlet using atomic absorption spectrophotometry (AAS). The ability of mixture of construction waste, bentonite and lime used as a coating on the landfill liner was able to effectively reduce heavy metal compounds Fe (II) by 64.73%, Pb (II) by 94.77% and Cr (VI) by 77.91% with the composition of construction waste, 25% bentonite and 1% lime. Thus a mixture of construction waste, bentonite and lime can be used as an alternative liner in landfill Jatibarang Semarang.
