Abstract: Tanah mempunyai peran yang sangat penting dalam konstruksi sebuah bangunan, manfaat utama tanah adalah sebagai pendukung pondasi bangunan, oleh karena itu, dilakukan pengujian untuk mengetahui pengaruh derajat kejenuhan tanah gambut terhadap uji konsolidasi. Dalam penelitian ini, tanah yang di uji merupakan tanah gambut yang diambil dari jalan Pantai Labu, Emplasmen Kuala Namu, Kecamatan Lubuk Pakam, Kabupaten Deli Serdang. Pengujian ini dilakukan langsung di laboratorium Mekanika Tanah Universitas Katolik Santo Thomas, Medan. Dari hasil pengujian yang dilakukan, pengaruh derajat kejenuhan tanah lempung terhadap penurunan tanah yang diambil dari daerah Pantai Labu, Emplasmen Kuala Namu, Kecamatan Lubuk Pakam, Kabupaten Deli Serdang. Sampel A derajat kejenuhan 20%, sampel B derajat kejenuhan 25%, dan sampel C derajat kejenuhan 30%, Berdasarkan hasil pengujian konsolidasi didapatkan pada kondisi sampel A memiliki derajat kejenuhan sebesar 20 % nilai koefisien konsolidasi (Cv) 0,067 cm2/detik, nilai indeks pemampatan (Cc) 0,059 dan nilai koefisien konsolidasi (av) 0,017 cm2/kg. Sampel B memiliki nilai derajat kejenuhan sebesar 25 %, nilai koefisien konsolidasi (Cv) 0,061 cm2/detik, nilai indeks pemampatan (Cc) 0,048 dan nilai koefisien konsolidasi (av) 0,026 cm2/kg. Sampel C memiliki derajat kejenuhan 30 %, nilai koefisien konsolidasi (Cv) 0,051 cm2/detik, nilai indeks pemampatan (Cc) 0,082 dan nilai koefisien konsolidasi (av) 0,024 cm2/kg. dan didapatkan penurunan, sampel A dengan derajat kejenuhan 20 % mengalami penurunan sebesar 0,176 cm dengan pengembangan 0,45%, sampel B dengan derajat kejenuhan 25 % mengalami penurunan sebesar 0,146 cm dengan pengembangan 0,3%, dan sampel C derajat kejenuhan 30 % mengalami penurunan sebesar 0,369 cm dengan pengembangan 0,28% Soil has a very important role in the construction of a building, the main benefit of soil is as a support for building foundations, therefore, tests were carried out to determine the effect of the degree of saturation of peat soil on the consolidation test. In this research, the soil tested was peat soil taken from Jalan Pantai Labu, Emplasmen Kuala Namu, Lubuk Pakam District, Deli Serdang Regency. This test was carried out directly in the Soil Mechanics laboratory at Santo Thomas Catholic University, Medan. From the results of the tests carried out, the effect of the degree of clay soil saturation on soil subsidence was taken from the Labu Beach area, Kuala Namu Emplasm, Lubuk Pakam District, Deli Serdang Regency. Sample A has a degree of saturation of 20%, sample B has a degree of saturation of 25%, and sample C has a degree of saturation of 30%. Based on the results of the consolidation test, it was found that in the condition that sample A had a degree of saturation of 20%, the value of the consolidation coefficient (Cv) was 0.067 cm2/second, the compression index (Cc) value is 0.059 and the consolidation coefficient value (ain) 0,017 cm2/kg. Sample B has a degree of saturation value of 25%, a consolidation coefficient (Cv) value of 0.061 cm2/second, the compression index (Cc) value is 0.048 and the consolidation coefficient value (ain) 0,026 cm2/kg. Sample C has a degree of saturation of 30%, a consolidation coefficient (Cv) value of 0.051 cm2/second, compression index (Cc) value 0.082 and consolidation coefficient value (ain) 0,024 cm2/kg. and a decrease was obtained, sample A with a degree of saturation of 20% experienced a decrease of 0.176 cm with an expansion of 0.45%, sample B with a degree of saturation of 25% experienced a decrease of 0.146 cm with an expansion of 0.3%, and sample C experienced a degree of saturation of 30%. decrease of 0.369 cm with expansion of 0.28%.
