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.

Abstract

Labor’s productivity is one of the success factors in construction project. The optimal labor’s performances can be measured using the productivities coefficient of the workers. The coefficient of productivities known as BOW analysis is further updated into SNI analysis. However, the value of labor’s coefficient productivity may be different at each location depending on their performances. For example the steel work labor’s who perform their work either outside or inside the project site. Therefore, this research takes some work sites on the steel workshop and the storey building project. The purpose of this study is to know the coefficient of labor’s productivity of steel working on the workshop and the storey building project. Then, the results of the observation is compare with the benchmarks that presents at this moment, which is BOW and SNI so can be obtained the optimum coefficient values of productivity. The results revealed that the coefficient’s value of steel labor productivity for foreman in workshop, building project, BOW, SNI are 0.0179, 0.0089, 0.00 and 0.004 respectively. The value of coefficient productivity for chief worker in workshop, building project, BOW, SNI are 0.00, 0.0089, 0.255 and 0.007 respectively. In the building project, the foreman and the chief worker do not only do steel working but also doing other types of job so it assumed that both of them are doing only 60% in steel working. The value of coefficient productivity for Vulcan in workshop, building project, BOW, SNI are 0.0359, 0.0592, 0.675 and 0.07 respectively. The value of coefficient productivity for assistant worker in workshop, building project, BOW, SNI are 0.0887, 0.0726, 0.675 and 0.07 respectively. Based on the coefficient value, it can be concluded that the order value of the optimum coefficient productivity of the worker is in the  workshop, building projects, SNI and BOW.

Abstract

Construction project have problems regarding waste, which can be in forms of Physical Construction Waste and Non-Value Adding Activity. The purpose of this research is to evaluate waste that occured in construction projects, while the aim of this research is to know the frequency and impact of waste, as well as the waste cause factor. The object of the research was waste on building project in the area of Semarang. Waste identification was carried outfrom literature, observation and interview and wereanalyzed using fishbone diagram to get waste cause factor variable. Waste variables were divided into four categories, i.e. waiting periods, material, human resources, and operations. Waste cause factor variables were grouped into six categories, i.e. people, professional management, design and documentation, materials, execution and external.Questionnaires were distributed to 100 respondents of 12 different contractors, with response rate of 65%. Data was processed by Weighted Mean Score (WMS) method. The results of this research showed that “extra work” waste had the highest frequency, “rework and repair” waste had the highest impact, and “slow drawing revision and distribution” and “design changes”, were the highest waste cause factors on building projects in the area of Semarang. The results of data processing also showed that structural works was type of work where waste often occurred. The result of risk-waste matrix showed that “extra work” was included into high risk-waste category which means it could cause serious disruptions to the project execution and company’s finance.

Abstract

Flood is a disaster that has the biggest threat, in terms of the number of victims or losses. Semarang City is a city that is classified as a flood prone area, this is due to the geographical location in the lowlands and highlands. The impact of the flood disaster caused damage and losses from various sectors of public infrastructure including the education service sector and health services. Damage and loss of public infrastructure will burden the government in the post-flood recovery phase. An assessment of infrastructure damage and losses from flooding is needed in order to help the Semarang City Government prepare a budget plan and manage rehabilitation and reconstruction. The purpose of this research is to explore the loss of public infrastructure due to the impact of the flood disaster, so that it can accelerate the post-disaster recovery process and management strategies for the risk of further flood disasters. The valuation method used is ECLAC (Economic Commission for Latin American and the Caribbean) Method. This method can identify damage and estimate the losses caused by floods. The results of this study are that each public infrastructure building has a different level of damage and loss and the budget allocation for disaster management each year is still inadequate. A risk transfer strategy is needed with an insurance financing scheme based on the level of risk in each infrastructure building.

Abstract

While the need for water supply infrastructure development keeps increasing, many local governments of Indonesia are facing problems related to limited funding. This condition opens up an opportunity for private sector to invest in water supply infrastructure projects through Public Private Partnership (PPP) scheme. As this scheme is relatively new for many local governments in Indonesia, its complexity and typically long duration of the concession period may raise concerns of potential risks throughout the project life cycle. It is, therefore, very important for public sector as owner of the project to understand and to be able to manage risks properly throughout the concession period. The aim of this research is to evaluate risk management of West Semarang Water Supply PPP Project as perceived by public sector. The objectives are to identify, to analyze, and to allocate risks to the right parties. Qualitative and quantitative approaches have been used for the research method. Data were collected through focus group discussion involving 16 relevant officials of local government of Semarang, including its Regional Water Supply Company (PDAM). This research has identified a total of 66 risks as perceived by the public sector, which are then classified into 11 categories, e.g. political, operation, revenue, etc. The proportions of the level of risks are relatively balanced, as follows; low (37.88%), moderate (28.79%) and high (33.33%). In terms of risk allocation, 46.97% of risks are allocated to the public sector, while 37.88% and 15.15% of the risks are allocated to the private sector and shared by both parties, respectively. The results of this research are valuable for the local government of Semarang and can be used as a guidance in managing risks of the PPP project throughout the concession period.
