ABSTRAK
Penelitian ini  membahas tentang proses stabilisasi  tanah pada proyek Jalan Tol Trans Sumatera 
Bakauheni  ?  Terbanggi  Besar  paket  2  Sidomulyo  ?  Kotabaru.  Pekerjaan  penggantian 
(replacement) tanah dilakukan di sepanjang ±24 km (setempat) sepanjang jalan tol. Pada tahap 
analisa daya dukung tanah asli, dilakukan pengujian Dynamic Cone Penetrometer (DCP) dan 
Tes  Sondir  guna  mengetahui  kedalaman  tanah  keras.  Kemudian  dilakukan  penggantian 
(replacement) tanah dengan material sesuai spesifikasi. Penimbunan material tanah dilakukan 
secara bertahap  dengan dilakukan  pengujian  Sandcone  di setiap  layer.  Kemudian  dilakukan
penelitian dengan pengambilan sample tanah timbunan pada 68 titik lokasi. Setelah dilakukan 
pengambilan  sample, selanjutnya dilakukan analisa di laboratorium mengenai daya dukung 
pada  sample  tanah tersebut. Parameter daya dukung yang dianalisa  sebanyak  4 jenis, yaitu berat 
jenis tanah (Specific Gravity), kadar air (Water Content), analisa agregat (Sieve Analysis), dan 
batas  konsistensi  (Atteberg  Limit).  Mengacu  pada  parameter  tanah,  dilakukan 
pengklasifikasian  jenis  tanah  sesuai  AASHTO  M145  &  Casagrande  Soil  Classification 
System.  Terdapat lokasi yang mengalami penurunan pasca penggantian (replacement) tanah, 
yaitu  STA  52+000.  Sehingga  perlu  dilakukan  tindakan  stabilisasi  tambahan  yaitu  injeksi 
grouting  semen.  Peneliti  menganalisis  penurunan  (settlement)  tanah  menggunakan  metode 
interpretasi, hasilnya menunjukkan  bahwa  pelaksanaan  penggantian  (replacement)  tanah dan
injeksi  grouting  semen  dapat memperkecil angka  penurunan  (settlement) tanah  dari  sebesar 
15,07 cm menjadi sebesar 0,93 cm.
Kata Kunci :daya dukung tanah, penggantian tanah, injeksi grouting semen.

ABSTRACT
This paper discusses the process of original soil stabilization in Trans Sumatra Bakauheni  -Terbanggi Besar Toll Road Project Package 2 Sidomulyo  -  Kotabaru. The  soil replacement 
process  was  conducted  at  approximately  24  kilometers  along  the  toll?s  main  road.  At  the 
original  soil  bearing  capacity  analysis  stage  were  by  performing  a  Dynamic  Cone 
Penetrometer (DCP) and Sondir test  to analyze of  the deep of hard soil.  A  soil replacement 
was carried out to replace the original soil with soil that has  appropriate specification. the 
piling up process was conducted in stages, which has Sandcone in such of layer. Research did 
about the landfill sample was retaken and collected at 68 points. The stockpile soil samples 
collection was then followed by the analysis which was conducted in the laboratory to find the 
soil  bearing  capacity.  There  are  4  types  of  bearing  capacity  parameters  analyzed,  namely 
specific  gravity,  water  content,  aggregate  analysis  (Sieve  Analysis),  and  consistency  limit 
(Atterberg Limit). Refer to it, then there was classification of soil types according to AASHTO 
M145  &  Casagrande  Soil  Classification  System.  A  point  which  has  settlement  after  soil 
replacement is STA 52+000. So, there need to additional soil stabilization, that is cement grout 
injection.  Reseacher analyzed the soil settlement by interpretation method.  Results showed that 
soil replacement and  cement grout injection  could  decrease  a soil  settlement  about 15,07 cm 
to became 0,93 cm.
