Abstract

Rapid urban growth has caused an increase of infrastructure and building construction projects in recent years in terms of project scale and number. Many of which certainly involve the construction of deep foundation, including pile foundation. In particularly densely populated urban areas, the need for more environmentally friendly pile driving equipment, such as hydraulic static pile driver (HSPD), is therefore inevitable. The aim of this study is to give a problem solving about HSPD productivity using analytical model. The objective of this study is to produce curves model of HSPD productivity. An analytical model has been designed utilizing 252 data of point piling from the four projects and simulation, i.e. size of driven piles, piling depth, and cycle time. The result of model is nomogram of HSPD productivity against piling depth for 3 driven pile size such as equilateral triangle 32 cm, square 25 cm, and square 30 cm. The model average validity is 96.07% and deviation standard is 2.32%. The sensitivity value 95.154% for equilateral triangle 32 cm, 9.376 for square 25 cm, and 94.298% for square 30 cm of driven pile.

Abstract

The condition of buildings in the Semarang City, still needs to improve in reliability, this is because there are already several examples of building failures building before the design life, even up to swallow the casualties. From these problems the Government provides a solution in the form of SLF (certificate suitable function). SLF is a certificate issued by the local government to declare the reliability of a building, before the building is utilized / used. SLF was first listed on the Act No. 28 of 2002 regarding Building, Government Regulation No.36, and guidelines made by the Ministry of Public Works SLF 25 / PRT / 2007. Boundary problem in the research is the implementation of the SLF predicament for government-owned buildings in the city of Semarang by considering the function of government-owned buildings used for public purposes, while giving precedence to SLF buildings intended for public use such as: offices, schools and hospitals. For the implementation of the SLF field still constrained some major factors such as ownership of IMB is still minimal, as well as regulation of the mayors of Semarang on the SLF has not been established. To overcome the existing problems then use SWOT analysis. The use of SWOT aims to find an overview of the strategies of existing problems. In a SWOT analysis and supporting data needed SLF implementation constraints, which are then classified based on the strengths, weaknesses, opportunities and threats. After classifying the data and then given the weight of each. From the results incorporated into the subsequent weighting diagram SWOT analysis and obtained turnaround strategy. This strategy shows that the condition of SLF in Semarang is located on opportunities and weaknesses. Then, in solving problems SLF in the city of Semarang is by taking advantage of opportunities to minimize the weaknesses.

Abstract

Work on the building project requires a material that is more complex and involves many parties so that the building project has a high complexity compared to other civilian buildings. One of the complexity of such problems in the procurement of materials. Some of the things that causes this problem is the existence of an uncertainty in the supply of construction materials. Reinforcement steel is the main ingredient in development , especially the construction of the building. The need of reinforcing steel required at each work ranging from foundation work , beams , plates and columns. Therefore, the availability of steel reinforcement is a major priority so that there should be no delay in procurement. Delays of this material may be caused by uncertainties in procurement activity. Uncertainties in the procurement of materials sourced from four stages: stage supply chain activities supply, control, process, and demand. The stages of the supply chain to be a reference to analyze the possibility of delays in the procurement of a material. Thus, this study aims to determine how much time minimum and maximum time delay procurement of materials, the maximum possible delay in work activities and work activities that are most likely and dominant risk that affects the delay procurement of materials for steel material. The major delays in the procurement of material obtained from the analysis of probability and risk impact with monte carlo method and application assistance crystal ball. In the procurement of steel material analysis showed that a minimum delay of 2.20 days,17.05 days maximum, the maximum possible delay in work activities 15.05 days, and delays in work activities that are most likely 9.24 days. Sources of risk that affect the delay is on the demand stage that ordering additional material due to design changes, material delivery delays due to financial problems, and ordering additional material due to changes of function space.
