Abstract

Soft soil is not suitable for supporting construction that stands on it because it has low shaman power, high compressive properties, and little stability. The compressibility of the soil certainly affects the existing construction, especially if the settlement that occurs due to the compression of the soil is not permitted. While the low bearing capacity of the soil causes the design load cannot be carried out directly, it is generally given in stages. The advantage of providing the load that gradually causes the density of the soil will increase. The soil with increased density will increase the carrying capacity of the soil so that it can accept the load of the next stage. Increasing in bearing capacity is given due to the magnitude of the land subsidence that occurs. It is necessary to test with laboratory modeling. Soil samples were put in the test basin and given additional water to determine how things were in the field if the soil experienced an increase in water content. Soil samples were loaded and recorded the amount of settlement that occurred. Increasing bearing capacity by conducting direct shear test changes in the soil bearing capacity parameter values is known to correlate the magnitude of the decrease in soil that occurs. In addition, an analysis of changes in water content and soil volume weight was also carried out due to the magnitude of the decrease. From the test modeling results in the laboratory with a test basin, it was found that the greater the value of soil subsidence, the higher the cohesion value of the soil and the lower the shear angle in the soil. For soil, water content is inversely proportional to the decrease, the more significant the decrease, the smaller the water content. Meanwhile, the weight of the soil volume is directly proportional; the more significant the decrease that occurs, the greater the weight of the volume of the soil. Keywords: Settlement, Shear Strength Parameter, Soft Soil, Direct Shear Test.

Abstract

Work at height is a job with a high risk of accidents, such as in the formwork aluma system. Weak supervision and a lack of knowledge of the workforce on potential hazards and risk control of the formwork aluma system are some of the causes of the high incidence of work accidents in this work. This research was conducted on the formwork aluma system of the BRI Gatot Subroto tower project, South Jakarta. The goal is to determine the potential hazards and risk control of aluma system formwork. Risk analysis is carried out using the AS / NZS 4360: 2004 standard to determine the level of risk to the potential hazards of the aluma system formwork. Potential hazards in the formwork aluma system are falling, bumping, being cut, punctured and crushed, with the level of risk being at high, substantial, medium and low levels. Risk control is carried out by the control hierarchy, namely elimination, substitution, engineering, administration, and control of PPE. Keywords: AS / NZS 4360: 2004, Risk Analysis, Hazards, Aluma System Formwork.

Abstract

Many regions in Indonesia have a variety of soil types, one of which is expansive soil. Expansive soil has high shrinkage to be used as one of the road construction materials. The problem that is often faced in road construction with a subgrade layer of expansive soil is the high swelling potential. This research aims to find out the soil bearing capacity of expansive soil as subgrade layer when given a variation in water content above the value of OMC with 2 conditions,  soaked and unsoaked. From research results it was found that the increase of water content and treatment conditions on the soil affected the soil bearing capacity of the soil, where in the  unsoaked conditions, the higher the water content the greater the soil bearing capacity is. In soaked conditions, the higher the water content, the smaller the soil bearing capacity is. The higher the water content is, the smaller the swelling is. Keywords: Expansive Soil, Compaction, OMC, CBR, Shear Strength, Swelling.
