Abstract

Concrete is a mixture of Portland cement or other hydraulic cement, fine aggregate, coarse aggregate and water or without additives to form a solid mass. The researcher aims to find out how much influence the compressive strength of coco fiber concrete has with sea water as a solvent. The method used in this study was an experimental method, cylindrical concrete was printed with a size of 15x30 cm by adding coconut fiber to the concrete mixture with fc' quality of 22.5 MPa and as a comparison the researchers made samples of coconut fiber concrete with fresh water as a solvent. The results of this study with the addition of 1% fiber by weight of cement at the age of 3 days the compressive test reached 10.02 MPa for fresh water concrete and 6.51 MPa for sea water coir concrete. At the age of 7 days, fresh water concrete was 15.76 MPa, while coconut coir concrete was 7.42 MPa. For 28 days the fresh water concrete is 23.78 MPa, while the sea water coconut coir concrete is 14.72 MPa. The conclusion obtained in this research is that the use of sea water as a solvent in coconut coir concrete has decreased in strength by 23.53% compared to coconut coir concrete with fresh water as a solvent for 28 days of age.

Abstract

Column is a part of concrete structure that bears the largest axial compressive load. The use of stirrup reinforcement in columns can maintain strength and stability so that the load is distributed evenly. The Indonesian Structural Concrete Requirements for Building (SNI 2847:2019) requires the use of threaded steel bar in column structures. This research aims to determine the effect of using plain steel bars (BJTP) and threaded steel bars (BJTS) reinforcement with a spacing variation of 3 cm and 5 cm. The research was conducted by conducting cylinder concrete test with a diameter of 15 cm and a height of 30 cm, spiral reinforcement with a diameter of 10 cm, concrete cover of 25 mm, and plain and threaded steel bars with a diameter of 10 mm. The test object is divided into 5 conditions, namely without any reinforcement, plain steel bars reinforcement, threaded steel bars reinforcement, and variations of 3 cm and 5 cm spacing on each steel bar reinforcement. The concrete used is made of local materials Baula splits and Tamboli sands from Kolaka District. The test results on concrete at 28 days showed that the use of spiral reinforcement on cylinder concrete can significantly increase its compressive strength by more than 50%, even reaching above 100% at closer spacing. Spiral reinforcement with threaded steel bars shows better strength increase compared to spiral reinforcement with plain steel bars.

Abstract

One type of infrastructure that falls under the jurisdiction of the government is toll roads. Government restrictions provide investors with opportunities to collaborate in the construction of toll road infrastructure, one of which is the BOT (Build Operate Transfer) system. For investors, there are numerous risks associated with the deployment of toll roads with the BOT system. With research limitations at the construction implementation stage, the goal of this study is to pinpoint variables that could end up becoming hazards for investors during the toll road development process. In this study, observation, interviews, and questionnaires for the targeted target respondents were the methods employed. Quantitative statistical analysis is used in data analysis to create categories in the shape of quadrants. The research's findings identified 17 risk factors that are broken down into three risk sub-categories. According to the results of the quadrant charting, 1 variable (inflation factor) was at moderate risk, 2 factors (field conditions and predicted construction costs) were deemed to be high risk, 7 variables were at substantial risk, and 7 variables were low risk.

Abstract

Every railway infrastructure must be inspected to determine its condition and function, including railroad bridge. The current inspection method is still carried out manually, namely by directly inspecting the components of the railway infrastructure, of course, this will make the inspection time long. Inspection of bridge components in locations that are difficult to reach can use tools such as Unmanned Aerial vehicles (UAV) or Drones. This study aims at bridge components, damaged bridge components and the type of damage that occurs on Welded Through Truss (WTT) bridges. Video results obtained from drones were analyzed based on PM 31/2011 and PM 32/2011. The results of the analysis found that the damage that occurred was on the stringer, floor beam and top lateral bracing with the type of damage, namely corrosion/rust that occurred in all spans of the bridge. The underside of the bridge is still in good condition.

Abstract

Currently, there are risks that have hampered the growth of toll roads construction in Indonesia, one of which is land delays. Land acquisition delays can lead to increased costs and can reduce investment attractiveness. That the Government provides infrastructure guarantee, one of which is land acquisition guarantee. It is hoped that it can attract investors, but investors are required to pay guarantee fee which will add to investment costs. This study uses qualitative and quantitative methods. The results of the analysis show that if there’s no delay in land acquisition, the difference between NPV and IRR of project with guarantee and without guarantee is not too high (0,84% for NPV and 0,033% for IRR). This means that the provision of guarantee on the condition that there is no delay in land acquisition does not significantly affect financial feasibility. However, currently there are still many land delays, the option of using guarantee can be considered because there is compensation that can be used to increased NPV and IRR values in proper conditions when land delay occured and can attract investors to invest by providing certainty for lenders/investors through increasing the credibility of the Government and business entities to be able to repay loans.

Abstract

The design compressive strength (f’c) is 21,7 Mpa / K250 and the chemical liquid was used is Sika Cim.  Variation of Sika Cim adding that used is 0%; 0,3%; 0,5%; 0,8%; 1%; and 1,2% toward the weight of cement used. The each variation consists of 3 sample with 2 sample that will be at compressive strength tested at the age of 7 days, and 2 sample for compressive strength control that tested at the age of 28 days. From these all variations of Sika Cim adding, the optimum point for connection material can be founded and then it will used to fabricated house panel assembling which analise damage model of the connection. Then calculating the cost that used to make connection with the optimum Sika Cim adding, and then compare it with the cost of normal concrete with same quality. From this study can be founded that level of optimum Sika Cim is 2263,54 ml or 0,52% from the cement which used for 1 m3 volume of the concrete.. Level of Sika can increase 11,8 MPa of compressive strength or 58,38% from the normal concrete without Sika Cim. Sika Cim using at K200 concrete to produce K250 concrete is 1182,219 ml/m3, with 7,48% cost from total cost for each K200 readymix concrete. This Sika Cim adding can economize the cost for about Rp. 51.397,67 for each m3 concrete. The composition of the mixture with the optimum Sika Cim applied to the precast column beam connection material, produces a joint that has a good crack pattern.
