Pengujian Model Fondasi Kacapuri dengan Penambahan Strip Plat Kayu Ulin di Tanah Gambut

Abstract

This document serves two fold objectives: as the template as well as the guide for composing your paper. Please write the. The distribution of peat soils with high organic content in the Kalimantan region causes low soil bearing capacity and large soil settlement, which adversely affects construction projects. Local communities commonly use kacapuri foundations made from a combination of ironwood and galam wood, but these foundations are not fully effective in resisting loads. This research modifies the foundation by adding ironwood plate strips modelled through the Plaxis 2D program and continued with prototyping in the laboratory by providing loading tests. The data used is primary data from laboratory testing with soil samples taken from the location on Bondang Street, Palangka Raya City. Laboratory testing of the physical and mechanical properties of peat soil revealed a moisture content = 580.51%, volume weight = 1,06 g/cm³, specific gravity = 1.79, ash content = 4.65%, fibre content = 33.12%, cohesion = 0,0023 kg/cm², inner shear angle = 1.8856°, shear stress from the normal stress and shear stress relationship graph = 0.006 and soil shear strength in the range of 0.0064 - 0,0174 kg/cm². The modelling that has been done provides a modification with four strips of ironwood plate. The prototype made produces a decrease value according to SNI 8460: 2017 standard which is 2.5 cm in the Plaxis experiment the required load is smaller than in the laboratory. In Plaxis, a large load of 356.9 kg is required to achieve settlement, and a load of 380 kg is required in the laboratory settlement test.
