Abstract
Tanah dapat dibagi menjadi dua yaitu tanah non-kohesif
(cohesionless soils) atau tanah kohesif (cohesive soils). Tanah ekspansif
merupakan jenis tanah yang mengalami perubahan volume akibat adanya
perubahan kadar air dalam pori-pori tanah. Apabila kadar air dalam pori
tanah meningkat maka volume tanah akan mengembang, sedangkan
apabila kadar air tanah berkurang maka tanah akan menyusut(Chomaedhi
et al., 2007). Perilaku dan sifat-sifat lempung sangat bergantung pada
komposisi mineral-mineralnya, unsur-unsur kimianya, tekstur lempung,
dan partikel-partikelnya serta pengaruh lingkungan di sekitarnya. (Alaa &
Kurniawidi, 2015).Stabilisasi tanah dapat dilakukan pada kondisi tanah
yang buruk. Stabilisasi tanah dapat memperbaiki sifat fisik dan mekanik
tanah. Kondisi tanah pada Proyek Pembangunan Sarana Limbah di Pantai
Utara Lamongan ini memiliki sifat tanah lempung yang buruk, sehingga
perlu distabilisasi.
Penelitian ini bertujuan untuk mempelajari dan mengetahui sejauh
mana pengaruh campuran bahan kapur pada proses terhadap sifat-sifat
fisik, kuat geser tanah lempung campuran yang distabilisasi. Percobaan
dilakukan dengan mencampurkan tanah alami dan tanah kering udara
dengan kadar kapur bervariasi mulai dari 0%, 3%, 5%, 7%, 10%, dari
berat tanah kering. Uji fisik tanah meliputi analisa saringan, gravimetri,volumetri, dan atteberg limit. Sedangkan uji mekanik tanah setelah
dicampur berupa proctor standart, CBR (California Bearing Ratio), UCT
(Unconfined Compression Test) dan uji XRF (X-ray
Fluorescence Spectrometer) dan Uji SEM (ScanningElectron
Microscope).
Hasil penelitian yang didapat menunjukan bahwa tanah asli
memiliki jenis tanah lempung dengan plastisitas rendah. Dengan nilai
berat isi kering 1,52 gr/cm3 dan kadar air optimum 22,91%. Pada tanah
yang distabilisasi mengalami peningkatan nilai pada variasi kapur 3%
dengan nilai berat isi kering 1,53 gr/cm3 dan kadar air optimum 23,38%.
Pada pengujian CBR didapatkan peningkatan nilai terbesar yaitu pada
variasi kapur 3% dengan nilai 1,33% dibandingkan dengan nilai tanah asli
yaitu 0,98%. Pada pengujian UCT didapatkan peningkatan nilai terbesar
yaitu pada variasi kapur 3% dengan nilai 53,02 kN/m2 dibandingkan
dengan nilai tanah asli yaitu 28,44 kN/m2.
======================================================================================================
Soil can be divided into two, namely non-cohesive soils
(cohesionless soils) or cohesive soils (cohesive soils). Expansive soil is a
type of soil that changes in volume due to changes in water content in the
soil pores. If the water content in the soil pores increases, the soil volume
will expand, whereas if the soil moisture content decreases, the soil will
shrink (Chomaedhi et al., 2007). The behavior and properties of clay are
highly dependent on the composition of its minerals, chemical elements,
clay texture, and particles and the influence of the surrounding
environment. (Alaa & Kurniawidi, 2015).Soil stabilization can be done in
poor soil conditions. Soil stabilization can improve the physical and
mechanical properties of the soil. The soil condition in the Waste Facility
Development Project on the North Coast of Lamongan has poor clay
properties, so it needs to be stabilized.
This study aims to study and determine the extent of the influence
of the lime mixture on the process on the physical properties, shear
strength of the stabilized mixed clay. The experiment was carried out by
mixing natural soil and air-dried soil with lime content varying from 0%,
3%, 5%, 7%, 10%, of the dry weight of the soil.Soil physical tests include
sieve analysis, gravimetric, volumetric, and Atteberg limit. While the
mechanical tests of the soil after being mixed were in the form of standard
proctor, CBR (California Bearing Ratio), UCT (Unconfined Compression
vi
Test) and XRF (X-ray Fluorescence Spectrometer) and SEM
(ScanningElectron Microscope).
The results obtained indicate that the original soil has a type of
clay with low plasticity. With a dry weight value of 1.52 g/cm3
and an
optimum moisture content of 22.91%. In the stabilized soil, the value
increased in the lime variation of 3% with a dry density value of 1.53
g/cm3
and an optimum water content of 23.38%. In the CBR test, the
largest increase in value was found in the 3% lime variation with a value
of 1.33% compared to the original soil value, which was 0.98%. In the
UCT test, the largest increase in value was found in the 3% lime variation
with a value of 53,02 kN/m2
compared to the original soil value, which
was 28,44 kN/m2.
