The Behavior of Alternative Kacapuri Foundation on Alluvial Land of Central Borneo

Abstract

One of the traditional substructure forms of Borneo is the kacapuri foundation. Previous research conducted a study on this kacapuri foundation by making an alternative kacapuri foundation model by combining a raft of gelam wood with reinforced concrete pillars. The study was originally applied to peat soil, but in reality, the kacapuri foundation was applied to alluvial soils around riverbanks rather than on peatlands. Therefore, this study looks at how the behavior of bearing capacity of the foundation when it is applied on alluvial soil. The location of the study where is located in the traditional Dayak Ngaju tribe in Mandomai village, Central Kalimantan. As a reference the application of the form of foundation using the model of Dayak house Huma Hai in the form of a house on stage with the main material of ironwood. The burden of each column of the house is 9,93 kN in the middle pole position. From the research, it is found that the ultimate bearing capacity is 298 kN /m2, with its own weight is 4,816 kN.
