Abstract:
Liner has a role as sealing or waterproof layer that was made to prevent water to be
absorbed by the soil. A good liner is made within the minimum hydraulic conductivity (k) within
the requirements of 1.0E-07 cm/s. This study was conducted to determine the extent on
the difference between hydraulic conductivity (k) bentonite and termite nest (Macrotermes gilvus
Hagen) as one of the materials that have the potential to obtain small value of hydraulic
conductivity (k). This research was conducted by examining the effect of hydraulic conductivity (k)
value on the percentage of additives, such as bentonite and termite nest material (M. gilvus Hagen),
and then compared the hydraulic conductivity (k) values of those two materials. The variations in
the additive content percentage are 5%, 15%, and 30% with laterite as a base material. Based on
the results of falling head test at minimum density of 95% γdmax, the smallest hydraulic
conductivity (k) value was obtained by bentonite with 30% mixed percentage level of 6.9390E-08
cm/s and the smallest hydraulic conductivity (k) value of termite nests was 1.2646E-07 cm/s with
the content percentage of 5% mixture.
