Abstract

The soil occupies an important role in the construction of a building, the main benefit of the soil isas a foundation of the construction, there are several soil shear strength tests, such as DirectShear Test, and Vane Shear Test. Each test can produce different test results for the same testobject. This may occur due to different testing procedures and workings of different tools as wellas the main test result targets of each equipment in the determination of soil parameters.Therefore, a careful soil investigation is needed, especially to determine the degree of saturationin peat soils by using soil shear strength test. In this study, the soil tested is a type of peat soiloriginated from the Rawa Seragi area, Belimbing Sari Village, Jabung District, East LampungDistrict.The tests were conducted directly in the laboratory for 12 (twelve) points and at differentdepths with Vane Shear and Direct Shear tools used to calculate the soil and maximum readingability on the torsimeter dial. Based on the test results obtained the average shear strength valueof Vane Shear on saturated soil at 30cm with an average value of 0.0379 and at a depth of 50cmwith an average value of 0.0384 and on unsaturated soil at a depth of 30cm with an average valueof 0.0434 and at a depth of 50cm with an average value of 0.0406 thus obtained a decrease of0.0066.Keywords: Degree of Saturation, Peat Soil, Shear Strength Test

Abstract

Lampung University as one of the first and oldest universities in Lampung Province is one of the best universities in Sumatra and continues to improve its academic quality, and have A Accreditation. The improvement of Lampung University facilities and infrastructure is continuously conducted in order to improve both academic and non-academic quality. The form of non-academic quality improvement is environmental arrangement with the drainage system planning. It is intended to solve some of the flood puddles that occurred during the rainy season due to the lack of optimal condition of existing drainage in the University of Lampung.The analysis conducted in this research includes hydrological analysis and hydraulics analysis. Hydrological analysis aimed to calculate the discharge plan using rational method and hydraulic analysis aims to calculate the capacity of existing drainage channels. So we can know the position of the flood point and planning the new channel dimension.Based on the analysis of the flood point occurred at DN15 cross section with 9.5 m long overflow which is located in front of the entrance portal of Faculty of Mathematics and Sciences. There are also some new drainage section design at DN63 point along 56 m, DN64 along 45 m and DN65 along 67 m as they are still a natural drainage. It is also necessary to give the drainage channel maintenance by channel normalization, garbage retaining lattice installation, and periodic cleaning of channels.

Abstract

The occurrence of floods at Raden Gunawan 2 street, Rajabasa district, Bandar Lampung was caused by the inability of existing drainage channels to accommodate direct run-off discharge and blockage of drainage channels by garbage.Hydrological analysis was performed by using the maximum rainfall data within the last 10 years, then, parameter calculation were performed to calculate the discharge plan using rational method. The wide-scale of watershed is 0.77308 km2 and the drainage coefficient is 0.5132. The hydraulic analysis was conducted to calculate the drainage channel discharge capacity using continuity formula and Manning formula, after that, suitable systems and dimensions were planned.Based on the results of the research, the suitable rain distribution is Log Pearson III Distribution which obtained rainfall value of plan for the 5-year rework time of 109,016 mm and the amount of the biggest discharge at joint segment between primary channel and Kemiling area is 2,8336 m3 / sec. Then, flood heights were found in the research area as high as 10-30 cm, because the existing dimensions were not able to accommodate the discharge plan. Thus, suitable channel dimensions are planned using U-Ditch shaped sections with U100 / 100, U150 / 150, U150 / 250 and U250 / 250 sizes. So, the discharge plan (Qr) is smaller than the discharge channel (Qs). Keywords: drainage, hydrology, hydraulics, distribution.

Abstract

One of the causes of construction failure on asphalt pavement is segregation. Which  is the separation of small and large aggregate grains within a mixture, so that in a part of the coating of the pavement will be concentrated aggregate coarse and in other part will be concentrated fine aggregate. One of the factors causing segregation is the hauling distance from Asphalt Mixing Plant to the slap location. To understand this, task a study on the impact of the transport process on segregation on hot asphalt mixture from Asphalt Mixing Plant to the location of the spread. The mixture used is the Asphalt Concrete-Wearing Course type or the laston coated wear of Asphalt Mixing Plant PT. Gigging Polah Raya for work location which is 28.9 km on Jalan Sultan Agung, Bandar Lampung, Lampung and PT. Rindang Tigasatu Pratama for work location located 53.3 km on Jalan Teuku Cik Ditiro, Bandar Lampung, Lampung. Examination of sample is done trough extraction test and sieve analysis test. From the result of the research, it’s found that there is being segregation during the transport of asphalt mix mixture from Asphalt Mixing Plant to the slap location. For sample PT. Manggung Polah Raya, gradation aggregate is still within the upper and lower limits of the general specification Bina Marga 2010. As for the sample of PT. Rindang Tigasatu Pratama, the aggregate gradation is out of the upper and lower limits of the general specification of Bina Marga 2010. Factors affecting segregation are haulage distances and aggregate density. Keywords: Road Pavement, Asphalt Concrete, Segregation.

Abstract

Feasibility Analysis is an appropriate analysis of parameters to determine a successful implemented project or not. Feasibility analysis is divided into two parts economic and financial analysis that both affect the feasibility of a project. The purpose of this study is to determine the costs incurred in a railway shortcut project, to analyze delay times before and after a railway shortcut, and to find out which railway shortcut project meets the economic and financial feasibility requirements. In this study, an analysis of the economic and financial feasibility and summarize the economic viability benefits of the Tegineneng - Tarahan shortcut project was conduct. A project is declared feasible or not by doing comparison with the feasibility method that is NPV> 0, BCR> 1, PP faster than the specified time, IRR> capital cost, and PI> 1. This study uses full occupancy rate with discount rate of 5% , 10%, and 15%, respectively.Based on the results obtained in terms of economic feasibility analysis that investment evaluation does not qualify due to the amount of benefit is too small so that economic analysis is not feasible. The aspect of financial feasibility analysis and analysis by summing the two financial and economic benefits is eligible so that the Tegineneng - Tarahan shortcut project is categorized as feasible. Keyword : Economic Feasibility, Financial Feasibility, Feasibility Method

Abstract

Water problems consist of three types: flood, drought, and water pollution. Floods are recognized as a significant source of threat to human life. One of the flood prevention actions that can be done is to optimize the drainage channels. Drainage can be defined as a technical action to reduce excess water so that the function of the area or land is not disturbed. University of Lampung is one of the locations prone to flooding. Therefore, a research to overcome the flood that occurred at the University of Lampung has been conducted (Case Study: Zone III Rectorate Area - Faculty of Agriculture). The purposes of this research are to analyze the drainage system of University of Lampung and to design drainage system that fulfill flood discharge plan. The research was conducted by survey in the field. The analysis conducted in this study include hydrological analysis and hydraulics analysis using HEC-RAS4.1.0 application. Calculation of discharge plan using rational method.. Based on the analysis results, there are no channels that are not sufficient for flood discharge, but there are some channels that are disconnected and cause the water to not flow. The disconnected channels are located on the channel with the DN5 and DN62 codes. For that, it is recommended to create a channel connecting DN62 channel with DN63, and make a channel on channel DN5 to DN65. The budget required for the repair of this channel is Rp 207,203,725.00 (Two Hundred Seven Million Two Hundred and Three Thousand Seven Hundred Twenty Five Rupiah).Keywords: Drainage, HEC-RAS, hydrology, hydraulics, floods
