Abstract

Physical properties of organic soils have a very high water content and low carrying capacity.One method to increase the carrying capacity of the soil is by adding or mixing with materials thathave a high carrying capacity. By adding sand on the sample in this study is expected to increasethe carrying capacity of organic soils of compressive strength and strong shear. The study wasconducted in the laboratory of Soil Mechanics Faculty of Engineering, University of Lampung, bymaking a sample of the results of compaction standard, then the samples are given the addition ofsand to the percentage increments of 5%, 10%, 15%, and 20% for the comparison of thecompressive strength (qu), shear angle (φ), and the value of cohesion (c) after the addition ofsand.Results of testing the compressive strength and shear strength showed soil behavior in a state ofthe sample with the addition of sand up to 20% has an increased qu and φ, but a decline in thevalue of soil cohesion. The more increasing mix of sand in the soil samples, the values ofcohesion / coherence on the ground will be more decreased, but the sand has good gradation andstrong grain will be able to withstand the load that works vertically or horizontally.Keywords: Organic Soil, Compressive strength and Shear strength, Friction Angle, and Cohesion.

Abstract

Way Besai river is located in Sumberjaya subdistrict, West Lampung district, Lampung. It is one of the sub river from Tulang Bawang river. Way Besai river has been used as a the electric power source, known as Besai hydropower. Besai Hydropower has decreased energy supply of 40 MW from the supply optimum can reachs 90 MW. his is due to the catcment area conditions of the Way Besai rivers are "metastable" so which effected in the shallowing of the cross-section quickly. So it needs the capacity increased of the cross-section of the river until the early condition where is the supply can reachs 90 MW.For the first step in improving the capacity of the Way Besai river needed hydraulics river simulation process that facilitated by using Hydrologic Engineering Center-River Analysis System (HEC-RAS) Program. HEC-RAS program can help to modeling the flow of cross-section of the river on the existing condition and normalization using the steady flow options and data input including maximum discharge data. The output of modeling using HEC-RAS program can be seen in the form of pictures and a table that presents the characteristics of a cross-section of the river.From the result of the analysis founded that to reach the normalization condition, needs the dredging until the elevation +713,00 level, with 2.435.590,09 m3 of volume capacity of dredging. When the water level of the river reachs Full Supply Level (FSL) elevation that is on elevation +722,00 level founded that the maximum discharge in the downstream in the amount of 57,19 m3/s, with water volume capacity in the 1.471.185,77 m3.
