Abstract

A housing development project is a project with certain resources and a certain time limit to obtain construction results. However, in practice there are certain risks. Therefore, good risk management is needed to get the desired results. The purpose of this study is to identify risks in the construction of the GRIYA PESONAN INDAH Housing Project and how to respond to risks. Identify risk by using the Risk Breakdown Structure (RBS). Classification of risk between impact and intensity using the Pobability impact matrix. Furthermore, risk analysis uses the Analytical Network Process (ANP). ANP is appropriate to be applied to decision making that faces interrelated factors and systematic feedback. Through RBS can be shown 6 risk groups with 24 risk items. With expert respondents, ANP results show that the most dominant risk group among other risk groups is the risk of the construction process. Meanwhile, among the 24 risk items, the risk of coordination and poor performance is the most dominant risk. Furthermore, from the experts obtained recommendations for solutions to the dominant risk, namely by providing training, tightening evaluation.

Abstract

Trisakti II Port, located in the city of Banjarmasin, South Kalimantan, is one of the ports that uses RTG cranes. Constraints often arise due to the lack of support for the container/CY stockpiling field due to the elevation of the field under the highway. So that when it rains, the container yard is often flooded, causing physical damage to the container and its cargo. And the type of soil in the study area is soft soil, so planning for a good and efficient foundation structure is needed. The purpose of writing this thesis is to determine the comparison of the costs and construction time used in the modified deck on pile and chicken claw structures. Determine which is more efficient between the deck on pile foundation structure and modified chicken claw. With the method of comparing the total cost of the budget and the time required for the implementation of construction. The results of this study are the results of the comparison of time and cost of deck on pile and modified chicken claw on the RTG Pad foundation work is the modified chicken claw foundation structure is 15% more efficient and 26% faster in execution time with a labor ratio that only differs 1 people per day. In terms of time and cost between deck on pile and modified chicken claw, it is found that the use of modified chicken claw structure is more efficient than deck on pile structure in this RTG Pad foundation work.

Abstract

Toll roads are public roads that are part of the road network system and as national roads, for which users are required to pay tolls. The existence of toll roads is very important in the smooth flow of traffic along with the increasing amount of traffic caused by the increase in the number of vehicles and the condition of arterial road pavements that have been damaged (wavy and cracked) at several locations on the road and congestion that occurs due to damaged roads. damaged. The benefits of toll road operations are to influence regional development and economic improvement, as well as increase mobility and accessibility of people and goods, also provide benefits to users in the form of saving vehicle operating costs (BOK) and time compared to passing through non-toll roads, as well as providing returns on investment, maintenance, and toll road development for the Business Entities involved. One form of cooperation between the government and the private sector is the construction of the Pasuruan-Probolinggo (Paspro) Toll Road. Through the Toll Road Business Entity (BUJT) PT. Trans-Java Paspro Toll Road, the government cooperates in the construction of a 31 km toll road. PT. Trans-Java Paspro Toll Road received a 45-year concession to operate the toll road. The purpose of this study was to determine the investment feasibility of the Pasuruan-Probolinggo Toll Road based on the investment feasibility parameters of Net Present Value (NPV), Benefit Cost Ratio (B/C Ratio), Internal Rate Return (IRR), Payback Period (PBP), and determine the length of time. payback period (Payback Period) Pasuruan-Probolinggo Toll Road, and get a comparison of Vehicle Operating Costs (BOK) between Toll Roads and Arterial Roads. The final result of the analysis obtained that the NPV value was negative Rp. -1,773,803,000,000, and the IRR value is 9.56%, which is smaller than WACC = 13.07%, and the BCR value is less than 1.00, which is 0.763 so that it can be seen that the investment is not financially feasible for investors. However, BEP < 45 years concession period is April 2043, so it can be seen that it is still in the feasible category. The Vehicle Operational Cost (BOK) for arterial roads is Rp. 3,647/km for Goal I, Rp. 6,413/km for Gol II, Rp. 9,498/km for Gol III, Gol IV, and Gol V. Meanwhile, BOK for toll roads and added toll tariffs of Rp. 3.226/km for Goal I, Rp. 6,767/km for Gol II, Rp. 7,763/km for Gol III, Rp. 8.113/km for Gol IV and Rp. 8,463 for Gol V. From the analysis it is known that the cost of passing through the toll road is cheaper than going through the arterial road for all vehicle classes and is certainly very beneficial for toll road users.

Abstract

Mojokerto is the main supporting city for the capital of East Java Province. The city is experiencing very rapid development as seen from the local revenue which has increased every year. The city of Mojokerto is one of the areas included in the Surabaya metropolitan area, namely Gerbangkertosusila. Currently, there is the Surabaya - Mojokerto Toll Road, which is often called the SUMO Toll Road. As is the case with Sekar Putih Street in Mojokerto City, this road is an alternative road that connects the Mojokerto city area with Mojokerto district if there is congestion in the Mojokerto city area, especially the Mojokerto bay pass road, then this route will be used as an alternative road with heavy vehicles passing by on this road. But the problem is that Jalan Sekar Putih has poor soil carrying capacity, so the road is often damaged and bleeds quickly, so the city government often has to carry out repairs/maintenance on Jalan Sekar Putih. So it is necessary to do a study by comparing the types of construction that are efficient with the Velue Engineering Method between Flexible Pavement structures and Modified Chicken Claws (results from VE) which are used to solve problems on the Sekarputih road in Mojokerto City.The results of the analysis of cost requirements and their maintenance costs are more efficient. Modified Chicken Claws and time for the construction of the Modified Chicken Claw system are 11.11% more efficient than Flexible Pavement construction.written in Indonesian and English with the following qualifications: 1 paragraph, spaced 1, font size 11 pt, Cambria 250 – 300 words. Abstract contains the background of the research, objectives, research methods, conclusions and contributions of researchers in scientific field.

Abstract

The success of a project cannot be separated from a series of activities which include the stages of planning, implementation and supervision. In the implementation of a project can experience delays, acceleration, or on time according to the schedule of the project plan. This research takes a case study of a futsal field construction project with a duration of 14 weeks. The purpose of this research is to determine the cost and time performance as well as to control the achievement of project completion in accordance with the specified time with the addition of manpower. This study uses the Earned Value Concept method to control project costs and schedules. This method provides information on Cost Variance, Schedule Variance, Cost Performance Index, and Schedule Performance Index for a project in a reporting period. From this method, information is also obtained on the prediction of the amount of costs and the length of time for the completion of all work based on performance indicators when reporting. From the results of the analysis at the end of the review week in week 9, it shows that the costs incurred are lower than the budgeted costs and the implementation time is slower than the planned schedule as indicated by the value of CPI = 1,216 (CPI > 1) and SPI = 0.598 (SPI < 1). The results of the calculation of the estimated final project cost of Rp. 503,278,428 is less than the budget of Rp. 612,000,000 with an estimated completion time of 135 days which means slower than the planned 106 days while the remaining project completion time is 43 days. To control the late project so that the project can be completed according to a predetermined schedule plan, it is necessary to allocate labor: 35 workers, 4 masons, 10 welders, 8 mild steel workers, 2 plumbers, 2 plumbers, carpet fitters. 7 people, 23 painters, 11 electricians, 5 head builders, 2 foremen
