    KARAKTERISTIK PULL-OUT RESISTANCE TULANGAN ROTAN SEBAGAI PERKUATAN PADA TANAH PASIR
    (2013-07-19) Harison, Victor
    Methods of soil improvement by using reinforcement was first introduced by Vidal (1966) and shown to reduce the deformation of both vertical and lateral directions. With previous research on the basis of pull test on soil reinforcement materials, there are other alternatives to conduct similar research with natural ingredients such as reinforcement materials. One of the natural ingredients that have not been used as a reinforcement material is rattan. While the type of soil used was sandy soil. Chosen considering the availability rattan material is so abundant in Indonesia. Association of Indonesian Rattan Furniture and Craft (2011) stated that Indonesia is the largest cane-producing countries in the world. Approximately 85 percent of the raw materials produced by Indonesian rattan. Used for this kind of rattan is Sega (Callamus Caesius) diameter of 8 mm. The purpose of this study was to test how much resistance rattan pull as reinforcement in reinforced soil structures at various levels of changes in water content, and the normal force is given above. Pull out resistance value of the soil reinforcement consists of longitudinal reinforcement frictional resistance and bearing capacity resistance on transverse reinforcement. Frictional resistance rattan reinforcement would be worth the higher ground when the water content of sand are in optimum condition (15%) with a note that the addition of normal stress has reached 0.05 kg/cm2 when laboratory testing. Bearing capacity value of resistance per unit area of rattan reinforcement will be highest when the soil water content of sand on the wet side of optimum conditions (16.5%) with the consideration of taking the maximum value of which does not have a broken rattan reinforcement of 3.422 kg/cm2
