Abstract

Soil is the material that serves as a support for the construction base. Each region has different soil characteristics in other areas, there has a carrying capacity of good to bad or poor. Clay and silt soil has a bearing capacity and low soil properties. To overcome this, the need to improve the soil natures with the stabilization method. Stabilization is to improve the physical and mechanical properties of the soil so that it meets certain technical requirements. One way is with a cement stabilization. In this study, the cement used is a cement-type portland cement. This study aimed to compare the value of CBR clay and silt before and after stabilized by the addition of cement and given soaking treatment. Soil used is a type of clay taken from the village of Rawa Sragi, District Jabung, East Lampung district and silt types from  Yosomulyo Village, East Metro District, Metro City. In CBR soaking test with mixture of 9% cement with modified proctor compaction and cured for 28 days, CBR values decrease to 28,7% for clay that soaked for 28 days, while the CBR value for silt soil with the same condition descease to 37,8%. The soaking treatment is proven to decrease the value of CBR significantly compared with the optimum condition of both soil.

Abstract

Soil permeability value for every construction is different. Such differences affect the strength of acivil construction to be built. Therefore it is necessary to attempt to manipulate the soilpermeability value by adding the additive to a soil permeability values obtained in order to meetthe standard of civil construction to be built. Among the many additives are used as soilstabilization materials, one of them is rice husk ash. Some recent researches in the field of CivilEngineering showed that rice husk ash mixture useful as a particularly clay soil stabilization.Because rice husk ash can fill the cavities that exist between the grains of ground.Soil samples tested in this study is clay derived from Perumahan Bhayangkara, KelurahanBeringin Jaya, Kecamatan Kemiling, Bandar Lampung. Rice husk ash used were obtained fromDusun Dantar, Kecamatan Padang Cermin, Kabupaten Pesawaran. This study was conducted todetermine the effect of rice husk ash to the soil permeability values.The results of analysis and calculations performed in the laboratory obtained averagepermeability value (k) for soil with 5% rice husk ash added, 10% rice husk ash added, and 15%rice husk ash added. The permeability value used to be compared with native soil (clay).Key words: clay, rice husk ash, permeability.

Abstract

Kekuatan tanah dasar memegang peranan penting dalam mendukung suatu konstruksi seperti; jalan, bangunan gedung , jembatan dan sebagainya. Dan untuk menilai kekuatan tanah dasar tersebut, dipergunakanlan nilai CBR (California Bearing Ratio). Tetapi seringkali di lapangan, karena keterbatasan transportasi pada daerah pedalaman dan ketersediaan alat pengujian yang cukup memadai, alat yang paling mudah untuk mendapatkan nilai CBR dari tanah dasar tersebut dapat digunakan alat Dinamic Cone Penetrometer (DCP). Dari data pengujian alat DCP tadi, dengan menggunakan fungsi logaritma tertentu sesuai dengan besaran sudut konus dari alat DCP, yaitu 30o atau 60o, yang kemudian digambarkan dalam grafik hubungan antara besaran penetrasi dan jumlah tumbukan, didapatlah besaran nilai CBR. Grafik hubungan yang digunakan adalah perumusan dari Smith dan Pratt, 1983 untuk sudut konus 300 dengan persamaan Log CBR = 2,503 – 1,15 (Log DCP), dan TRL, Road Note 8, 1990, untuk sudut konus 600 dengan persamaan Log CBR = 2,48 – 1,057 (Log DCP). Sebelumnya sudah ada, grafik hubungan DCP dan CBR, akan tetapi untuk menentukan nilai CBR yang dihasilkan, harus menggunakan cara diterawang menggunakan kertas lain, dan hal ini cukup menyulitkan jika titik yang diuji sangat banyak jumlahnya. Dengan perhitungan logaritma yang diaplikasikan ke grafik dan persamaan fungsi, diharapkan dapat mempermudah dan mempersingkat waktu yang dibutuhkan untuk mengolah data DCP yang diuji. Kata kunci : Tanah dasar, grafik DCP, hubungan DCP dan CBR, logaritma DCP

Abstract

Clays and silts have the low strength compressive. Clay is a kind of fine grain soil that has a low bearing capacity and very sensitive to changes in water content. To improve soil conditions then soil reinforcement is done by using lime substance. The clay soil sample is a type of high plasticity clay that taken from Rawa Sragi- Jabung- East Lampung district and then the silt soil sample is taken from Yosumulyo-East Metro- Metro City. Based on previous experiments, that soil is included in soft clay and high plasticity category. Based on Unified Soil Clasification (USCS), clay belong to CL category, While silts belong to Cl-ML category. In unconfined compressive strength test, clays and silts with variation of curing time and unsoaked condition, soil with hydrated lime mixtured with modified proctor compacted, for clays,Qu value increased with the addition of lime content.  It get Qu optimum value increased when it has 12% hydrated lime content, 28 days of curing time. For silts Qu optimum value inscreased when it has 12% hydrated lime content and 28 days of curing time. Hydrated lime adding could inscred unconfined compressive strength but with longer curing time duration (28 days). Because the greater Qu soil value is the greater soil bearing capacity.Keywords: Hydrated Lime, Clay, Silt, Unconfined Compressive Strength, Soil Bearing Capacity
