Abstract
Jembatan MERR II-C atau Jalan Middle East Ring Road IIC
(MERR II-C) dibangun sebagai penunjang fungsi sarana
transportasi yang cukup besar dan vital bagi kehidupan khususnya
daerah Surabaya. Berdasarkan hasil pengujian tanah di daerah
sekitar jembatan (sumber: data pengujian tanah di Laboratorium
Mekanika Tanah dan Batuan, Jurusan Teknik Sipil, FTSP – ITS,
Surabaya), jenis tanah sekitar adalah tanah lempung lunak. Pada
tanah lempung lunak, masalah yang akan dijumpai bilamana
harus mengkonstruksikan bangunan di atasnya adalah daya
dukung tanah yang rendah serta kemampatan tanah yang relatif
tinggi (Wirawan,2011).
Pada penelitian ini akan dilakukan analisa mengenai
penurunan tanah pada daerah sekitar Jembatan MERR II-C,
dengan menggunakan metode GPS untuk mendapatkan nilai
penurunan tanah di sekitar jembatan. Titik – titik kontrol yang
diamati ada 12 titik yang tersebar di area sekitar jembatan.
Pengamatan dilakukan 3 kala yaitu pada bulan September,
Oktober dan November 2015.Hasil dari pengamatan 3 kala
tersebut diperoleh nilai titik yang mengalami penurunan tanah
terbesar adalah pada titik 8 sebesar 23 mm dan kenaikan tanah
terbesar adalah 4 mm pada titik 4.

MERR II-C bridge or road Middle East Ring Road II-C
(MERR II-C) constructed as a support function sizeable
transportation and vital to life, especially the area of Surabaya.
Based on the results of soil testing in the area around the bridge
(source: soil testing data on Soil and Rock Mechanics
Laboratory, Department of Civil Engineering, FTSP - ITS,
Surabaya), the type of soil surrounding is soft clay. In the soft
clay soil, the problem will be found when the need to construct
buildings on it are low soil bearing capacity and congestion
relatively high ground (Wirawan, 2011).
In this study will be an analysis of land subsidence in the
area around the bridge MERR II-C, using a GPS to get a
reduction in the value of the land around the bridge. Point - the
point being observed there are 12 control points scattered in the
area around the bridge.
Observations were made 3 time is in September, October
and November 2015.Output of observations obtained when the
point value of land is the biggest decline 23 mm at point 8 and the
largest land rise is 4 mm at point 4.
