Abstract

Marshland is a soft soil containing clays, silt and peat. The clay / silt is a type of plastic cohesive which hasadhesive properties between the grains and able to be permanently formed continuously with relativelymoderate pressure without breakage. However, clay or silt becomes inconsistent with loading, resulting in alarge decrease (instability). Marshland has an unstable behavior requires an effort to fix it. One of the effortsto repair the marshland chemically can be done by reusing waste wood and glass bottle waste as stabilizationmaterial. Waste wood is burnt to ash and the waste of glass bottles is recycled by being crushed to becomepowder. Waste wood and waste powder of glass bottles serve as fillers and binders on marshland.Based on the test result, the optimum percentage value of wood waste ash addition and powder of glass bottlewaste in marshland with mixture of 10% wood waste ash and 10% powder of glass bottle waste with 7 days ofcuring with CBR value of 4.5325%. This indicates that the land with the CBR value (CBR 3% - 7%) can beused as a subgrade layer for residential roads or local roads with low traffic

Abstract

Iron ore as a raw material of steel reinforcement in concrete can not endeavor to increase production because it is a natural resource that is not renewable. To overcome dependence consumption of reinforcing steel in the concrete is then used altrenatif other material as the reinforcing steel that is easy, inexpensive to obtain and resistant to corrosion, namely in the form of reinforcement of rattan sticks. It is intended that the natural resources we have can be reused to the maximum. This study uses a cane kind seel as reinforcement concrete beams. Tests conducted by the method of loading one point, cracks are expected in this test is failed bending. Reinforcement made from 1 piece of iron reinforcement and 2 rattan wrapped reinforcement wire reinforcement bendrat round face, it is expected that the adhesion reinforcement with concrete stronger. Testing was done by testing reinforced concrete beam flexural capacity using a type of reinforcement rattan cane plain size OD OD 20 mm and 30 mm. With the quality of the concrete used for fc '= 18.675 MPa. The test specimen concrete beam flexural capacity was only 28 days with the test method fourth point loading system.
