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.

Summary

Introduction

In South Borneo, which is a tropical region with many forests, the availability of various types of wood affects traditional building materials that exist. The traditional substructure forms of Borneo community are ironwood pile foundation, gelam wood pile foundation, big stem foundation, and kacapuri foundation. Kacapuri foundation itself is a combination of ironwood pile foundation which is supported by a number of gelam wood in form of a raft. A., et al (2013) [1] 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. This https://doi.org/10.10 51/matecconf /201928004009 alternative design is made because ironwood becomes rare nowadays in the market so it is replaced with a concrete pillar. Gelam wood that is submerged in the swamp continuously has power for tens of years
