Abstract

 In building a construction related to the physical condition of the soil, this is because the land It is one of the very material plays an important role in supporting such a construction.Then had to do the testing power support basic land (subgrade) with experimental study testing the California Bearing Ratio (CBR) method of pressure (pressure method) based on the energy compaction. The research using a sample of the soil that came from the area of Tirtayasa, Kec.Sukabumi, Bandar Lampung for land fill. Implementation testing of CBR compactor modification press tool with using three soil samples at each pressure.The pressures used for CBR standard is 0,10 MPa, 0,26 MPa and 0.58 MPa. And for testing using pressure modified CBR 0.437 MPa,1,19 MPa and 2,63 MPa. The results of the research in the laboratory showed that the weight of the maximum volume (γdmaks) of 1.68 g/cm3 of standard proctor method.While of modified proctor testing the the weight of the maximum volume (γdmaks) of 1.77 gr/cm3. Based on the results of testing the value of CBR standard and modified methods of compared that the laboratory testing higher than the CBR based on compaction energy with press modifications. Keywords : CBR, Compaction Energy Tool press the Compactor Modification

Abstract

Rainfall data is one of the data which plays an important role in order to calculate construction project, especially for flood hazard zone nor near the river zone and coastal area. In rainfall data recording sometimes an unwanted thing happened like a rainfall data vacancy in certain area, this is certainly has an impact on the construction’s calculation. On a missing rainfall data, predictions can be made using the method of reciprocal, normal ratio, an algebraic average. The purpose of this sudy is to determine the correlation value from the result of rainfall data predictions by comparing the correlation values of these three methods by using three stations R002,006,R018 in pringsewu regency. This study also aims to determine the fluctuations in the results of these three methods, which methods produces the best correlation and not too fluctuating in order to replace the missing rainfall data. The results of this research that has been done, using the method of reciprocal obtained that standard deviation give the best result among other I 0,22 which is categorized as poor value and the result of correlation average is 0,36 which is categorized as good enough. This result is the best value among the other methods which is calculated using data per years for 34 years.Keywords: algebraic average method, reciprocal method, normal ratio method, missing rainfall data, pearson correlation, standard deviation.

Abstract

Improving the Infrastructure development needs the soil that capable to support the load. It because soil is a material that major the role to support every construction. To identify a good soil is by doing physical and mechanical soil test. Soil compaction is process of increasing the soil density by reducing the particles proximity so it can reduce the air volume. Soil type is influencing to the maximum dry volume weight and optimum water content of that soil. Based on the soil type, compaction is divided into four types. In this research is using two types of compactions that are type A and Type C with purpose to find out the effect of soil particles diameter by passing sieve analysis to soil compaction using standard method.Compaction is done based on blow method and pressure method. In pressure method is using modification compaction tool with 5 Mpa, 10 Mpa, and 15 Mpa pressures.The result of this research is the blow method compaction type A has a higher water content than type C, but the value of maximum dry volume weight Type C higher than type A.  In pressure method it can be concluded that as the higher pressure so the water content and the maximum dry volume weight are also getting higher.Keyword:Soil Particles, Standard Method of Compaction, Blow Method and Pressure Method Compaction

Abstract

The safety level of a slope is influenced by several factors, including factors tilt and loads working on it. Slope conditions with large loads and steep slopes can cause landslides. The influence of heavy rain flushed the majority of the region martapura - baturaja cause landslides and slope at some point in double track train along 50m which have geographic condition consists of the land pile of high steep, so prone to landslides. This is certainly very dangerous for trains, and around the slopes a solution is needed that can be an alternative to make the slope safe from landslide hazards. Based on the laboratory tests that have been carried out of the samples were taken from the site, so the analysis of the existing slopes stability with computer analysis shows the condition of unstable because from the result of numerical safety value analysis 1,731 for condition 1 and 1,732 for condition 2, so that needed reinforcement on the slopes itself. From the analysis of the slopes stability which has been strengthened with a combination of retaining Wall of land and drill pile using the Computer Analysis obtained greater numerical safety value compared by only reinforced with retaining Wall land for 3,978 to condition 1 and 3,983 to condition 2, so the design of strengthening is safe and able to withstand landslide. Keyword : Borehole Data, Geoelectric, Computer Analysis using methods Fellenius

Abstract

Composite beam is a combination of concrete and steel profiles. Nominal flexural strengthanalysis of composite cross-section can be calculated manually, but it takes a long time or are notefficient when calculating the nominal flexural strength analysis of composite beams. In this study,it can be a formulation of the problem is how to apply the analysis to the nominal flexural strengthcomposite into android-based programs. The purpose of this study in this thesis is to simplify thecalculation of the nominal flexural strength analysis of composite beams using android basedapplication program. Object-based research to create a program that profiles IWF android withconcrete (composite beam).In the implementation of this study using two methods: the method of literature study (study oftheory) and methods of software development (analysis, design, coding, and testing).This program has been tested with manual calculations that show the results accordingly. Fromthe test results indicate that the ease of use of program-based program that android is moresimple and easy to use in the field.Keywords: composite beam, android, nominal flexural strength analysis
