Abstract

Congestion problems are common in transportation, congestion can be caused by several things. The construction of the flyover is expected to be able to overcome congestion in the long term. This research was conducted to determine the effectiveness of the flyover construction on the Teuku Umar - ZA Pagar Alam road. This research was conducted during busy hours on Monday at the Teuku Umar road, ZA Pagar Alam and the nearest intersection.. From the results of calculations and analysis, it can be seen that the construction of an elevated bridge has no significant impact on the decomposition of the congestion problem in the Kedaton area and its surroundings, this can be seen from the level of service on all roads in the study area with a value of V / C Ratio <0.75. Meanwhile, the average degree of saturation obtained from the analysis of intersections with signal and no signal> 0.75. Construction of a flyover which illustrates that it will unravel traffic jams, in fact the performance of the flyover and the main road underneath has not increased. This needs to be addressed immediately considering the current traffic flow in Kedaton and its surroundings is already saturated. Therefore, the growth of vehicles is on time, and public transportation facilities need to be improved. So that people begin to switch to public transportation in order to reduce the incidence of congestion on these roads. Keywords : Road Performance, Degree of Saturation, Level of Road Service

Abstract

The flexural strength of rigid pavement is the dominant parameter that influences the concrete pavement performance. In general, concrete is weak against its flexural tensile strength. One alternative that can be used to increase its flexural tensile strength is by adding artificial fibers and/or natural fibers to the concrete mixture. The purpose of this research is to find the effect of adding gelam bark fibers towards compressive strength, split tensile strength, and flexural strength of concrete using PCC cement. In this study, the concrete mixture was added with various percentages of fiber content i.e. 0,2%; 0,3%; 0,4%; 0,6%. The concrete was tested and compared its value of compressive strength, split tensile strength and flexural strength. The results of this study showed that the most influential use of fiber for concrete pavement was 0,4%. The addition of gelam bark fiber by 0,4% could increase the tensile strength of the concrete mixture aged 28 days and 56 days respectively by 6,95% and 23.72% toward the concrete without fibers. The testing of concrete at 28 days age results the split tensile strength value decreased by 4,2% and the compressive strength test decreased by 4,7%.Keywords: Gelam bark fiber, PCC cement, OPC cement, flexural tensile strength, split tensile strength and compressive strength

Abstract

Continuous waves crashing into the coastal area can cause abrasion on the coast and damage facilities and settlements in the area. Therefore, a coastal protection building is needed to reduce wave energy before arriving at the beach such as a breakwater. To design a breakwater it is necessary to pay attention to wave deformation, one of which is wave diffraction. Where the wave when obstructed by an obstacle will bend around the end of the obstacle and enter the protected area behind it. The complex phenomena of nature are described in terms of equations, but they are difficult to solve analytically. So in this study solved numerically with the help of a computer with 2D wave simulation software based on the principle of the hyperbolic equation propagation model. Then get the results in the form of diffraction coefficient values that are close to the results obtained in the physical model research that has been carried out. Changes in wave height occur after passing through the breakwater which indicates a change in energy from before and after passing through the breakwater.

Abstract

The high level of seismic activities in Indonesia causes the planning of building structures to be taken into account against the acceleration of the earthquake on the ground. Earthquake acceleration on the ground is an earthquake parameter that has a direct impact on the structure. Time history dynamic analysis can represent the dynamic properties of earthquake acceleration and structural response. So that this analysis method can provide a more complete description and information on structural responses. Earthquake recording data uses actual 3 earthquake accelerograms which are scaled with the planned earthquake response spectrum. From the results of this study, it is found that according to ATC-40 the building structure is included in the damage control category. Meanwhile, according to SNI 1726 (2019), the Chi-Chi and El Centro earthquakes met the requirements for deviation bricks between permit floors, but in the Kobe earthquake, the building structure did not meet the deviation requirements between permit floors on the 3rd floor.

Abstract

Loss of land due to coastal erosion that occurs naturally by wave abrasion. Therefore, to protect the coast from erosion or other matters, a breakwater is needed which destroys the energy of the waves before reaching the shore. This is the background of the author in taking the title of the thesis about the Performance Analysis of Wave Attenuation in the Hollow Type Breakwater Submerged Type 2-D Physical Modeling. The variables used in this study were incident wave height (Ho), calm water level (ds), and breakwater type. The results of this study indicate that the damping coefficient (Cr) was obtained using a sinking breakwater without a hole with a calm water level (ds) of 2 cm of 0.479 which is the most effective damping produced in an experiment using a breakwater that is free from calm water surface (ds). 2 cm. The wave attenuation obtained from the wave defraction test using 2 types of breakwaters resulted that the breakwater without the damping hole was greater than using a perforated breakwater.
