Perilaku Penurunan Tanah Terhadap Dry Side of Optimum dan Wet Side of Optimum pada Kepadatan Tanah Organik

Dony Rizky Pratama, Setyanto Setyanto, Muhammad Jafri

Abstract


The decline in soil organic matter due to the burden of its own soil and building construction there
on are not able to with stand the load that lasts. Of these conditions need to know the factors that
affect soil instability, through soil behavior can be observed with the organic content of the soil
water content. The compaction is the beginning of the formation process for testing the strength of
the soil, so that the pattern of behavior can be identified by soil Dry and Wet Side of Optimum Side
of Optimum.
Soil test results Decrease Behavior Against Dry and Wet Side of Optimum Optimum At the Side of
Organic Soil density, Dry Side of Optimum sample / sample with 5% dry compaction over the best
sample for the fastest processing speed and magnitude of soil degradation as well as the smallest
decrease in the reduction process quickly said to be good for the soil more quickly reach the soil
layer in a stable condition and the magnitude of the smallest drop is quite good because the
compression process a smaller type of soil, thereby reducing the risk of damage to the construction
thereon that the Cv value obtained by 0,168cm 2 / sec, Cc for 2.33, and AV 0.28 cm 2 / sec.
Keywords: Organic Soil, Compaction, Dry Side of Optimum, Wet Side of Optimum, and Soil
Declinel.
