Abstract

Tanah gambut adalah tanah dengan karakteristik yang khusus, salah satunya adalah memilikikadar air yang cukup tinggi sampai 400%. Penelitian ini bertujuan untuk mengetahui karakteristiktanah gambut dan kuat geser pada tanah gambut desa Lalombi akibat pengaruh temperaturdan waktu pemanasan.Pemeriksaan fisik tanah gambut meliputi pemeriksaan uji kadar air asli dengan tingkatpemanasan dan waktu pemanasan yang berbeda, uji kadar abu dan organik, uji berat isi, ujibatas-batas Atterberg, uji berat jenis, uji penyerapan tanah dan uji kuat geser tanah dengan alatVane Shear Test.Proses pemanasan tanah gambut dengan temperatur dan waktu pemanasan yang berbedadapat mempengaruhi kadar air yang hilang dan kadar air yang tersisa di dalam rongga tanahgambut. Semakin tinggi temperatur dan lama waktu pemanasan, maka kadar air yang hilangsemakin besar. Kadar air maksimum yang hilang mencapai 125,682% dan kadar air yang tersisa didalam tanah gambut mencapai 0.231%. Nilai kuat geser tanah gambut desa Lalombi km. 65meningkat seiring bertambahnya suhu pemanasan dan lama waktu pemanasan, nilai kuat gesermaksimum tanah gambut adalah mencapai 38 kPa pada temperatur 100oC dan lama waktupemanasan 72 jam.

Abstract

The limitation of soil data due to poor soil investigation process is a common problem in civil engineering project. The finite element method was used to analyse the compatibility of foundation to support silos in Liverpool Docks. Both shallow foundation and pile foundation were considered. The results of the analyses are presented by comparing analytical and numerical solution. Parametric study was considered for each case. There are different results for two types of shallow foundation that had been considered. Strip foundation seemed more reliable than pad foundation, while Pile foundation considered to be first choice due to the satisfactory condition for all factors.

Abstract

The use of natural fibers as a reinforcement material in clay becomes an alternative choice of materials widely used in the early decades of soil improvement techniques. This practice is to improve soil strength and resistance to cracks. This preliminary practice was done because the cost of procurement is relatively low cost and also available in almost all areas of Indonesia. Modification of the use of natural fiber with other materials such as synthetic fiber materials has begun to do a lot at this time. The objectives of this research are: (1) Analyzing the physical and mechanical of soft soil mineralogy characteristics, (2) Analyzing the soft soil mechanical behavior by reinforcing  the Palm oil  fiber  (POF) of  the empty fruit bunch of palm oil whether it can increase soft soil capacity, (3) shrinkage and crack intensity factor (CIF) of soft soil in wet-dry cycles. The results showed that the addition of natural fiber on soft soil tends to reduce the level of soil density and increase the water content of the soil, although not too large. The effect is only about max 2.35% on 2% fiber content. While the swelling potential and shrinkageof the soils can be reduced by fiber reinforcement. In the crack potential test showed a substantial reduction of  crack intensity factor, whereas the addition of fibers in the soft soil can reduce cracks up to 444%. This shows that the fiber-soil has great ability in resisting the tensile strength of the soil-fiber interface due to the adhesion properties so that the soil is not easily cracked

Abstract

Sebagian besar wilayah Indonesia terdiri dari tanah lempung termasuk desa Tanamea, kecamatan Banawa Selatan, Kabupaten Donggala, Sulawesi Tengah. Tanah lempung merupakan tanah yang memiliki daya dukung rendah dan penurunan yang besar. Penelitian ini bertujuan untuk membandingkan karakteristik mekanis tanah lempung sebelum dan setelah distabilisasi secara kimia dengan penambahan zat aditif. Dalam penelitian ini bahan stabilisator yang digunakan adalah Magnesium Chloride dan semen dengan variasi kadar campuran zat aditif 0%, 5%, 10%, dan 20% terhadap berat kering tanah lempung. Dalam penelitian ada 3 tahapan, 1.) pengujian sifat fisik tanah untuk menentukan klasifikasi tanah lempung. 2.) pengujian sifat mekanis tanah lempung, dan 3.) pengujian sifat mekanis tanah yang telah dicampur dengan zat aditif. Hasil pengujian sifat fisik tanah lempung menunjukkan bahwa tanah yang digunakan adalah tanah lempung organik dengan nilai LL > 50 yang termasuk dalam plastisitas rendah. Adapun pengujian mekanis tanah yang dilakukan yaitu, pemadatan, kuat tekan, pemampatan dan geser langsung. Hasil pengujian mekanis tanah menunjukkan penambahan campuran zat aditif dengan berbagai variasi kadar campuran pada tanah lempung organik, membuat nilai wopt cenderung menurun hingga 8,85% dan berat isi kering maksimum yang juga ikut menurun hingga 38,25%, meningkatkan nilai kuat tekan bebas tanah mencapai 56,21%, menurunkan nilai penurunan tanah, menurunkan nilai kohesi tanah lempung hingga 64,59%, serta meningkatkan nilai sudut gesek tanah lempung hingga 65,05%. Hal tersebut karena adanya proses sementasi, dimana air didalam pori-pori tanah akan mengikat zat aditif yang mengakibatkan terbentuknya butiran sedimen. Dari hasil penelitian, pencampuran zat aditif membuat tanah menjadi semakin ringan dan lebih padat, sehingga meningkatkan kekuatan tanah. Pada kadar campuran 10% zat aditif pada tanah diperoleh nilai kuat tekan yang terbesar dengan nilai wopt yang terkecil, serta nilai kohesi terendah dan nilai sudut gesek yang tertinggi dari pengujian

Abstract

Problems in the basic soil layer, which is generally sandy soil will greatly affect the life of the planned cracking and rutting in the construction of the paved layer. The purpose of this study was to determine the effect of CBR values on the Subgrade layer on the life of the paved road pavement plan until there began to be a fine crack on the paved road surface and predict the depth of rutting on the road surface when fine cracks began to occur. The method used in this study is the Determination of TYN and RDM Values using the HDM III. Based on the results of the analysis, it can be seen that the higher the CBR value, the longer it takes for a pavement to experience fine cracks as well as at the life of plans of 10, 15, and 20 years where the CBR value is directly proportional to the length of time a fine crack occurs. Predicted intensity of rutting (Decrease) at the time of the fine crack at the age of the 5-year plan, there was a decrease of 3.01 mm after 8.14 years of the road being opened. At the age of the 20-year plan, the value decreased by 2.33 mm after 5.438 years of the road being opened.
