Analisis Hubungan Ph Dan Kadar Fe Terhadap Elastisitas Pada Tanahdari Tempa…

A research has been done in analyzing the relationship between pH and Fe level to the elasticity of soil by using on ultrasonic wave principle. The samples have been taken from a TPA in Rumbai district, Pekanbaru. The samples of soil were taken from TPA in the West, Eart, North and South sides with the depths of soil were 10 cm, 20 cm and 30 cm respectively. The modulus elasticity of the sampl…
