Abstract

Bio-cover, originated from degraded solid waste also known as aged refuse, is an alternative of daily cover soil for landfill. This study aims to examine the use of aged refuse as a daily cover for landfill. Bio-cover type (old and young aged refuse) and thickness (15, 20, and 30 cm) were used as variables in this research. Result showed that an old bio-cover with 15 cm thickness can reduce 98.10% of methane gas. It can also retain rainfall up to 20.52%. The old bio-cover with 30 cm thickness can also reduce leachate production up to 31.82%. In addition, the results showed that the differences of methane gas and leachate reduction in 15 vs 20 cm bio-cover thickness were significant. However, there was no significant difference between 20 vs 30 cm of bio-cover thickness. It can be concluded that the ideal bio-cover thickness for landfill cover soil was 20 cm.
