Abstract

This study was conducted to determine what factors influence the differences in the results of the Bina Marga 2017 method and the AASHTO 1993 method and determine which planning results are more efficient to be applied to Letjen S. Parman Street. The research method used is a comparative method, using the existing data and the latest data from surveys. As a result of analyzing a rigid road plan with a planned age of 40 years, the Bina Marga 2017 method obtained a concrete slab with a thickness of 305 mm, and the AASHTO 1993 method obtained a concrete slab with a thickness of 280 mm. Further differences in results can be seen in the level of traffic load during the service life, the diameter of the dowels, the spacing of the tie bars, and the minimum design height of the subgrade embankment. The differences in the results of these plans are caused by two main factors, namely the factor of using the cumulative traffic growth value (R) in the Bina Marga 2017 method and the direct use of the subgrade CBR value in the AASHTO 1993 method. Based on the data that has been obtained, it is concluded that the 1993 AASHTO method provides more efficient results to be applied with considerations in terms of smaller plate dimensions and fewer connections and reinforcement requirements. Which when calculating the work cost, the AASHTO 1993 methods results give a smaller number of work volumes, so it has the possibility to provide a more economical work cost than the Bina Marga 2017 methods results.

Abstract

The application of graded concrete on structural elements is predicted to increase the capacity of the structural performance, serviceability, and to reduce costs compared to conventional concrete structures. This study aims to analyze (1) the load-deflection relationship, (2) the moment-curvature, (3) the deflection ductility ratio, and (4) the crack pattern. This study used reinforced concrete (RC) beams specimens with the dimension of 13x19x150 cm which was categorized as reference specimens and graded concrete beams. For reference specimens, an RC beam possessing concrete strength of 30 MPa; 40 MPa; 50 MPa were prepared; For the graded concrete beams, two specimens made of 30-40 MPa; 30-50 MPa; 40-50 MPa were prepared. In terms of casting graded concrete beams, low-strength concrete is placed on the tensile fiber of the beam, while on the compressive fiber of the beam, high-strength concrete is placed. The specimens were tested using the four-point bending method. The results showed that the increase in the concrete strength in the compression fiber of the beam contributed to the increase in load capacity, stiffness, and serviceability in the post-crack phase. The increase of concrete strength in compression fibers by 20 MPa is considered effective and has a positive impact on the moment-curvature capacity and is considered efficient in construction costs. The deflection ductility of the beam is classified as partial ductile and is adequate for structural design in earthquake-prone areas. A flexural cracks pattern was found on each specimen.

Abstract

The Epanet model in clean water pipelines is intended for time efficiency in calculating hydraulic behaviour. Calibration of the water pipe network is to compare the simulation results of the model to actual field observations and to see that the model that has been made is truly valid and reliable as a tool to determine the hydraulic behaviour of the network system when a change input into the system is given (e.g. the addition of pipelines and number of customer tapping debits). The pipe roughness coefficient (C) is a number that indicates the amount of energy loss due to friction between the flowing fluid and the pipe wall. The increasing age of the pipe will cause the pipe wall roughness to increase, and the energy loss will be even more significant. This research aims to calibrate the pipe network model by adjusting the C value of the actual pipe roughness coefficient according to the installed age. An initial simulation model was carried out by entering the standard pipe C value in the Hazen Williams energy loss equation in the Epanet link/pipe properties. Then a simulation is carried out by modifying the value of C according to the pipe's service life. For 600 mm steel pipe, change the C value from 150 to 87 (pipe age >30 years), HDPE 315 mm pipe changes in C value from 140 to 100 (pipe age >10 years) and 25-50 mm PVC pipe from 140 to 100 (pipe age >10 years). From the simulation results of the Epanet model-field observations, the average compressive height was obtained for five observation nodes.of 2 tails was performed paired sample test the pressure height value of the model-observation. Before modifying the value of C, the paired mean difference test results showed a significant difference between the simulation results of the model on field observations with a model significance value of 0.004, which means <0.005. There is a considerable difference between the simulations and observations, and the model is considered invalid. However, after modifying the value of C according to the actual age of the pipe, a paired sample test T average value of the compression model-observation was 0.098 > 0.005), which means that there is no significant difference between the simulation and observation. This means that the model made is quite valid. Product moment correlation between the model simulation height - field observations, the value of R = 0.967, the relationship is robust between the two results.

Abstract

Currently, the progress of infrastructure in Indonesia is very rapid, in its implementation the project must be in accordance with the planned time. Therefore there must be project control in terms of performance in terms of the amount of work time. The purpose of this study is to find out how long the delay is on the project and how long the work is completed with the conditions that occur in the field. In the construction project of the Aysha Cibinong Islamic Hospital, West Java, there was a delay from the plan that was supposed to be completed in mid-2021, but must be completed by the end of 2021. This was due to the previous contractor having problems, therefore the implementation of this project was in Take Over which resulted in project completion delay. The method used is the concept of Earned Value Analysis (EVA) to find out how much time the project delay is estimated to be. The budget plan is Rp.9,400,000,000 (nine billion four hundred million rupiah), the planning time is 90 calendar days, while the estimated time for completion of the project or Time Estimate which is influenced by the implementation of project work on the 8th week evaluation is 90 calendar days.

Abstract

From the government's perspective, an electronic tender or e-tendering system in the procurement of goods and services in Indonesia is a platform to acknowledge good governance and public services since it enhances cost efficiency, effectiveness, shorter turnaround periods, delivers excellent public monitoring, fosters competitiveness, and increases government accountability. Nevertheless, numerous tenders have managed to fail during the implementation of e-tendering for construction works. The purpose of this study is to identify the factors that contribute to tender failures throughout the Surabaya City area. The factors that contributed to the tender's failure were identified from the results of the 220 construction tenders stated on the LPSE website. Descriptive statistical analysis was used to obtain factors that cause e-tender failures from the data obtained. Administrative, technical, price, and qualification criteria are the most dominant four failure criteria. The most apparent cause for auction failure is the provider's inability to attach references to previous projects.

Abstract

Productivity is the ability to produce labor in completing the specified number of workers and determines the success of project implementation. Determination of minimum production through worker productivity analysis needs to be considered because it is correlated with the time of completion of work and affects the amount of project implementation costs required. The purpose of this study was to determine the productivity of iron workers in the construction project of the Aysha Islamic Hospital - Perum Accropolis Karadenan Cibinong Bogor. The method used for measuring productivity is work sampling with a productivity assessment approach of 12 (twelve) floor plate iron workers. The productivity value of iron workers varies every day, on the second day the lowest productivity is 28.85 Kg/Hour-Person and 33.55 Kg/Hour-Person on the thirteenth day being the highest productivity value. The average productivity obtained is 31.02 Kg/Hour-Person with a Labor Utilization Rate (LUR) of 74.27% over a span of 7 hours for 14 days.

Abstract

Japura Airport is one of the nodes of transportation that owned by Inderagiri Hulu (Inhu) Regency. The airport is located 14 km from the Pematang Reba. Pematang Reba is public administration office complex in Inhu Regency. This airport has flights within the province and even flights between provinces adjacent to Riau Province. The road that separates of these two cities is considered as the economic lifeblood of Inhu Regency to Riau Province. In addition, this road has fungtion not only to connect two important locations in Inhu Regency but also as only road access from Riau Province to Jambi Province. Because of the importance of this road, the condition of this road must be always maintained. Through this study, an analysis of the Remaining Structural Life (RSL) of the pavement was carried out to determine the most appropriate recommendations for road preservation work. The IRMS method is the method which used in calculating the remaining structural life (RSL) of the flexible pavement. The data requairement are deflection data from the Falling Weight Deflectometer (FWD), road geometric condition data and Average Daily Traffic (ADT). Through calculations, it was found that the apropriate flexible pavement preservation programs for Jalan Japura to Pematang Reba were divided into 3 types. Firstly, Overlays program are needed for STA 3+ 393 to STA 7+712, STA 8+509 to STA 15+70 and STA 16+510 to 16+819. Secondly, segment from STA 7+930 to STA 8+ 312 needs Reconstruction. Thirdly, STA 15+922 to STA 16+303 needs routine maintenance.
