Abstract

The soft clay soil has expansive behavior that expands when exposed to water, this will be very dangerous to the construction to be built on it, because clay soil generally has a low shear strength and high compressibility. To know the parameters and characteristics of strong clay soil shear in an area, can use vane shear test and direct shear test. The soil samples were taken from Jabung, East Lampung for testing laboratory modeling on glass box with vane shear and direct shear tools with a weight of  ± 130,730 grOn the direct shear tests when soil conditions remolded at a depth of 30 cm shear strength values obtained at 0.0743 kg/cm2, on vane shear test obtained 0.38 kg/cm2 with soil bearing capacity of 0.6048 kg/cm2, at a depth of 50 cm obtained a shear strength value of 0.0779 kg/cm2, on vane shear test obtained 0.54 kg/cm2 with soil bearing capacity of 0.6738 kg/cm2. In saturated soil conditions a depth of 30 cm obtained a shear strength value in the direct shear test of 0.0553 kg/cm2, the vane shear test of 0.46 kg/cm2 with a bearing capacity of 0.4116 kg/cm2, a depth of 50 cm obtained shear strength value of 0.0743 kg/cm2, the vane shear testing with a 0.65 kg/cm2 earned bearing capacity of 0.6308 kg/cm2. From the test results direct shear test and vane shear test known that the shear strength in direct shear tests is smaller than the vane shear test. Keywords: Vane shear, direct shear, Clay soil shear strength, Soil bearing capacity.

Abstract

Due to the development of housing in Bandar Lampung so rapidly, its specialty in Housing Bhayangkara, Village Beringin Jaya, District Kemiling. The process of absorption of water into the ground is not going well. Runoff rainwater that falls directly flowing into the drainage channel. Infiltration wells serves as a temporary rainwater that falls on the roof of the house, then the rain water will be absorbed by the soil. In this study determines the permeability coefficient values obtained by means of modified with different diameters, which will then be compared and a determination made as catchment wells. Based on the examination of the physical properties of the original soil, using samples that have been tested in this study, soil samples can be classified in the group of argillaceous soil, while USCS soil samples classified as clay and included in the CL group The results of the analysis and calculations performed, the permeability coefficient obtained for the field test tool diameter 2 ", 3" and 4 "as well as the permeability coefficient in laboratory research. The permeability coefficient used to calculate the amount of recharge wells that efsien. Keywords: clay, permeability, infiltration well

Abstract

Landslide is a natural disaster that often occurs in Lampung Province, particularly in WestLampung regency. The sliding occurs due to an increase in soil pore water stress in the rainyseason. Based on the research on the slopes, there is a safety factor value that can be used as areference for the degree of slope stability. One method to analyze the value of slope safety factoris by using the Geostudio Slope / W 2007 program.In this study, some cross sections of slope were simulated with 4 different water table conditions.The required soil properties index are: cohesion, c; natural angle of repose, φ; and unit weight ofdensity, γ .The analysis result shows that slope transversal cut shape have influence on slope stability. Theanalysis results on slopes with saturated conditions have a safety factor value of <1.25 and areclassified on unsafe slopes. In the unsaturated condition the whole simulation is classified as astable slope with a safety factor value> 1.25. Based on the analysis result, it can be inferred thatthe slope has insecured status. Thus, it is suggested to conduct such actions in order to preventlandslide.Key words : soil, slope stability, safety factor, geostudio slope/w.

Abstract

In order to obtain a good, strong and sturdy foundation layer, good soil carrying capacity is required.  In addition, the soil also serves to support the foundation of a civil construction such as buildings and pavement. Therefore it is necessary to do soil improvement for soil types that have low carrying capacity. In this final project, a research on high plasticity clay soil is taken from Sidorejo area, Sidomulyo district, South Lampung to find CBR value with variation of immersion time.  From this research, we can see the change of CBR value with immersion variations that have been done for 4, 5, 14, and 28 days.From the research conducted in the Laboratory of Soil Mechanics of Lampung University , it is known that the soil originating from Sidorejo area, Sidomulyo District Southern Lampung is classified into A-7-5 clay soil which has a soil bearing capacity value of 7%.  After the improvement of soil with lime additive substances with optimum content of 12% and 3,472 gr of matos stabilizer which is then done with immersion test with a duration of 4, 5, 14 and 28 days, the value of CBR is 24% at 4 days, 22% at 5 days, 15.6% at 14 days and 9% at 28 days.  The value of CBR obtained tends to decrease as the duration of immersion is increased, so it can be concluded the duration of immersion greatly affects the size of soil bearing capacity.

Abstract

This research conducted to study the characteristics of daily rainfall and model making ofsynthetic daily rainfall in Pringsewu regency using periodic model, stochastic model and periodicstochastic models. This research conducted using daily rainfall data with length of 1984-2013from three rainfall stations, Pringsewu, Wonokriyo and Banyuwangi rainfall stations.These models performed by using 512 days annual data. Using rainfall frequency obtained andapplying the spectral method and the least squares method, it can be generated the daily rainfallperiodic models. Rainfall stochastic model assumed as the difference between rainfall data withperiodic rainfall models. Based on data from the series of stochastic, the component wascalculated using the approach of autoregressive models. Stochastic model was presented by usingthe autoregressive model of order three. Periodic stochastic model obtained by merging periodicmodel and stochastic model. Model validation and data obtained by calculating the correlationcoefficient. Based on the results of this research, it can be concluded that daily rainfall time seriescan be very significantly approximately recorded rainfall data. With the the average value ofcoefficient correlation of periodic model is 0.98019, coefficient correlation of stochastic model is0.99808, and coefficient correlation stochastic of periodic model is 0.99993keywords: daily rainfall, autoregresif models, stochastic component.

Abstract

Soils have different types and different carrying capacity. One of them is clay soil that has the low carrying capacity. Viewed from the rapid development of infrastructure in Indonesia, does not rule out the possibility that the infrastructure built in areas with clay soil types. Given the small carrying capacity of the clay, the soil should be improved in order to support the development of a construction.soil improvement with an additional mixture of rice husk ash and matos as stabilizer can improve soil quality. This research was conducted with rice husk ash mixture of 6%, 8%, 10%, and 12% and matos with level 3,3898% gr. Then, curing for 7 days, 14 days, 21 days, and 28 days without immersion. Soil that used in research is from Sidomulyo, South Lampung is a type of clay soil that belongs to the A-7-5 group based on the AASTHO classification. Research in laboratory showed that 28 days of curing with 12% rice husk ash mixture had the highest CBR value from other curing durations. Soil clay CBR value increased from 7.3% to 31.8%. This shows that the ash mixture of rice husk and matos is quite effective in increasing the carrying capacity of clay soil. Keywords : Matos, CBR, Rice Husk Ash
