Abstract

The construction of the Jakarta Kemayoran Tower was carried out using a mechanical coupler connection in the building column construction, because overlapping or conventional connections are not the right way to connect reinforcement. The main reinforcement in the column uses threaded iron with a diameter of 25. The mechanical coupler connection method used in this study is a coupler grip, with the planned tensile strength of the reinforcing steel being 525 N/mm². The column structure that is sampled is the main column with the size of the main steel reinforcement ≥ 32 mm. This study focuses on the analysis of quality tests and cost plans. The analytical approach used is descriptive analysis by looking for a comparison of the two variables. Testing the tensile strength of concrete reinforcement using a mechanical coupler connection showed successive results of 621.04 MPa, 624.86 MPa, 625.41 MPa, these results exceeded the minimum limit specified in SNI-2052-2017, namely 525 MPa. Meanwhile, the calculation of connection costs using the mechanical coupler method requires a total cost of Rp. 139,824,000, - while the cost of using a conventional connection is Rp. 191.161.127,-. From the calculation results, it is obtained that the difference is 37% cheaper than conventional reinforcement connections.This research can be used as a reference in alternative selection of reinforcement joints.

Abstract

The area of West Sumatra which is at the confluence of 2 tectonic plates and 2 faults makes the area prone to earthquakes. One of the cities that has experienced an earthquake is Solok. One of the impacts of earthquakes is liquefaction events, namely the loss of strength of the sand layer due to increased pore water pressure. So that in planning construction in Solok it is necessary to review the potential for liquefaction in order to reduce construction damage and prevent liquefaction. To find out the potential for liquefaction as expressed by the value of the safety factor, it can be analyzed using standard penetration test data, namely N-SPT. The safety factor used in this study is the probability of 500 years and 2500 years. The results of the analysis of the safety factor obtained show that at each depth of the soil layer under review it has a value of < 1 so that the potential for liquefaction is quite high. The lowest safety factor is obtained at a depth of 4 – 6 m for a 500 year probability and 6 -7 m for a 2500 year probability which ranges from 0,12 – 0,16.

Abstract

In terms of transportation, the service of toll road infrastructure is the main factor that must be considered, so it must meet the road geometric technical requirements, so that toll road users are safe and comfortable driving. The influence of centrifugal force that occurs in corners often results in less safety and comfort for toll road users, both drivers and passengers. The object of research is the Six Sections of the Jakarta City Inner Toll Road Section A, the Kelapa Gading – Pulo Gebang section because it is one of the toll roads that has good road geometry for horizontal and vertical alignments. The purpose of this study is to analyze the road geometry on the Six Sections of the Jakarta City Inner Toll Road Section A Kelapa Gading – Pulo Gebang Sta 24+850 – Sta 25+350. The method uses field research methods, analyzes and evaluates the data based on the 2009 Bina Marga. Data analysis is to determine the geometric design of a comfortable and safe toll road. The results showed that the results of the 2009 Bina Marga calculation analysis, obtained a design speed of 77 km/hour with R = 231 m and Ts = 287.51 m, while the actual field speed with a design speed of 77 km/hour R = 233.50 m and Ts = 247 m. So there are differences in the values of R and Ts due to limited land in the field and the maximum speed set is 70 km/hour. In this condition, the geometric design of the road must be in accordance with the conditions of the land in the field and conduct a preliminary survey using the Theodolit Station measuring instrument in order to obtain elevation data for different heights and contour conditions in the area to be built for a road.

Abstract

Congestion on Jalan Lenteng Agung Raya, South Jakarta is a fairly frequent occurrence, such as in the morning when people start leaving for their respective activities and also in the afternoon when they return from their activities. Another cause of congestion is the existence of a U-Turn at railroad crossings that are parallel to the road, so that when the train is passing, the vehicle will automatically stop to queue and wait for the train to finish crossing and be stopped by the occurrence of high side obstacles along the road. Lenteng Agung Raya. That way, the government plans infrastructure development in the hope of reducing the congestion problem, namely the U- Turn flyover. The flyover is expected to reduce congestion. The construction of the Lenteng Agung U-Turn Flyover caused an increase in traffic volume. This condition is analyzed by calculating the volume and capacity of the road per lane, the free flow speed and the degree of saturation, as well as determining the category of road service level. Before the flyover, Jalan Lenteng Agung was traversed by vehicles with a daily traffic volume of 2263 smp/hour per lane, vehicle travel speed of 14.4 km/hour. Q/C Ratio 0.52, including service level category C, where the flow is stable, but the speed and movement of the vehicle controlled by the driver is limited in choosing the speed. After there is an overpass, the daily traffic volume is 2466 smp/hour per lane, the vehicle travel speed is 25.71 km/hour. Q/C Ratio 0.58 is in service level category C where the flow is stable, but the speed and motion of the vehicle controlled by the driver is limited in choosing the speed. The increase in traffic volume and the increase in the speed of vehicle travel that occurs is thought to be due to a change in the reversal crossing which originally passed the railroad tracks so that long queues of vehicles on Jalan Lenteng Agung have been replaced by flyovers.

Abstract

At this time, planning for earthquake-resistant multi-storey buildings in Indonesia is important because Indonesia is in a very active tectonic zone, a position caused by the meeting of the 3 large plates and 9 small plates of the world & forming complex plates meeting paths, this makes Indonesia a countries vulnerable to earthquakes. One method of analytical approach for the performance of earthquake-resistant reinforced concrete structures is push load analysis which is used to reveal the performance of building structures during an earthquake by presenting them using performance levels according to regulations, so this planning is usually called performance-based earthquake resistant planning. The performance level will indicate the collapse behavior of the building during an earthquake according to existing conditions. Pushover analysis & performance evaluation on vertical and horizontal elements is assisted by ETABS software. The results of the pushover analysis show that the performance point of the rusun TNI AU Halim Perdanakusuma building for loading in the X-direction is 440.471 mm with a shear force of 38363.2261 kN, while for the Y-direction the performance point obtained is 457.276 mm with a shear force of 55150.5802 kN. From the performance point, the structural drift resulting from loading in the X-direction and Y-direction is 0.824% & 0.855%, so the structure's performance level is based on the drift limits required by FEMA 356 and ATC-40 including the direct occupancy level. Based on the capacity curve, the maximum base shear force obtained is 46734.5513 kN & the resulting displacement in the X- direction is 710.310 mm & while in the Y-direction, the maximum base shear force obtained is 76055.6401 kN & the resulting displacement is 904.504 mm.

Abstract

The construction of the Kataraja toll road is one of the government programs that are currently being implemented to balance the movement of people by driving. The purpose of this study is to analyze and compare the results of the calculation of the bearing capacity and settlement of the foundation. The foundation is the lowest part of the building structure which has the role of transferring the building load to the underlying soil or rock. The depth of the hard soil that becomes the foundation reaches 30 meters, so use a spun pile foundation. Analysis of pile bearing capacity and settlement needs to be considered to obtain an appropriate foundation plan and meet the requirements. There are several calculation methods in analyzing the bearing capacity and settlement of the foundation, but it is necessary to consider which method is relevant. The method used in the analysis of the bearing capacity of the pile foundation based on the SPT results is Mayerhof, the results obtained are (Qu) 633.92 kN and the calendering results using the Hilley method are (R) 1654.415 kN. Calculation of the efficiency of the pile group using the Coverese-Labbare Formula method, the result is (Eg) 0.574. Analysis of calculating the settlement of a single pile manually using the Vesic method obtained a result of (S) 2.62 cm with a reduction in permits of (Sir) 6 cm so that the single pile settlement requirements are met (SAFE). Analysis of group pile settlement manually with the Vesic method obtained results of (Sg) 5.34 cm and with the Plaxis 3D Application it was 6.71 cm with a decrease in permits referring to (BSN SNI 8460, 2017) of <15 cm, so the requirements on group pile settlement are met (SAFE).
