Permeability is the ability of garbage to be passed leachate or how much moisture can pass through garbage as long degradation (age) of garbage. Media (garbage) are degraded with the imperfect will affect the value of permeability (k) so as to allow the water did not pass but will flow down the sides of the side of the media (garbage). Permeability of waste will be measured using ASTM method D2434-68 while the gas permeability value was calculated according to Darcy’s Law. The results showed that age of garbage has negative correlation and influential significantly to liquid coefficient permeability (k). Increasing the age of waste samples has an effect on k value, k value tends to decrease with increasing age of garbage. The k value range is 0.10587 cm / s - 0.00525 cm / s, whereas in the intrinsic permeability of gas (K) the age of waste has a negative correlation relationship to the value of K gas but without significantly, the increasing age of the waste sample affects the value of K gas, tends to decline with increasing degradation time. The range of K values is 5.9 x 10-11 m2 - 2.14 x 10-11 m2. <br /> <br />
