Abstract

The analysis results indicate that the variables of material quality and construction work (X1) and project management and coordination (X2) have a significant impact on project effectiveness and satisfaction (Y), with path coefficients of 0.890 and 0.908, respectively. The R-Square value of 0.946 suggests that 94.6% of the variability in project effectiveness and satisfaction can be explained by these two variables. These findings highlight the importance of improving communication and coordination to achieve more effective and satisfying project outcomes.

Abstract

Electricity transmission towers require a solid foundation to support the structural load, one electricity transmission tower line is often located on diverse land conditions, such as rice fields, forests, plantations, and residential areas. With the closer location of towers to residential areas and limited land, slim type transmission towers that have minimal tower leg spans are an option for space efficiency. The purpose of this study is to determine the soil bearing capacity, tensile force, compressive force, soil settlement and iron diameter used in bore pile. This bore pile foundation stability analysis is located in Pasawahan Village, Dayeuhkolot, Bandung Kidul with tower type 4EE6+33 slim with a bore pile diameter of 60 cm and a depth of 17m. The analysis methods used are Reese & Wright Method, Converse-Labarre Method and janbu, Bjerum, and kjaernsli Method. The results of the analysis of the bore pile tower foundation type 4EE6 + 33 slim show a compressive force of 56.1 tons, a tensile force of 10.98 tons. While the analysis of the 60 cm diameter bore pile foundation at a depth of 17 meters shows the bearing capacity of the pile blanket of 3474.429 kN/m2, the bearing capacity of the pile tip of 721.286 kN/m2, the ultimate bearing capacity of 4159.714 kN/m2 and the allowable bearing capacity of 953.314 kN/m2 and the consolidation settlement analysis obtained results of 24.79 mm < 25 mm. Reinforcement calculation on bore pile tower foundation type 4EE6+33 slim bore pile reinforcement used 12 D19 mm and spiral reinforcement.

The analysis results show that mode 1 without walls is 1.675 seconds and walls are 0.441 seconds, the equivalent shear force in x and y directions without walls is 2284.35 kN and walls is 2478.83 kN, the dynamic earthquake shear force in x and y directions without walls is 2284.36 kN and walls 2479 kN, drift limit drift limit between floors without walls 94 mm and walls 32.9 mm,  stress is 45.357 N. Based on the results of structural behavior analysis of masonry earthquake resisting systems, without walls is more flexible than stiffer walls.

Abstract

The research evaluates the time and cost performance of the Wu Tower Project in Bandung using the Earned Value (EV) method. The scope of the research includes a comprehensive literature study on the concept of Earned Value (EV) and its application in the evaluation of time and cost performance of construction projects. In addition, the research also includes the measurement of the actual time and cost performance of the Wu Tower Project using the EV method, analysis of influencing factors, especially those related to design complexity, scope changes, and labor, as well as comparison of actual time and cost performance with predetermined standards. The performance of the project implementation time in the 1st month (one) to the 8th month (eight) is progressing well as indicated by the SV (Schedule Variant) variant value is positive or the SPI performance index ≥ 1, this indicates that the work is progressing both in schedule and budget. For the 9th (ninth) to 11th (eleventh) month, the SV (Schedule Variant) value is negative, which means that the work is delayed, but the project completion expenditure budget is still quite efficient because the SPI value is ≥ 1. Based on the Performance Index value, the overall SPI value gets an average value of 1.73, which means that the project is progressing towards time performance, while the CPI value generally gets an average SPI value ≥ 1, which means that the costs incurred are more economical, so that the project is more efficient.

Abstract

This research aims to analyze the influence of soil density levels on the California Bearing Ratio (CBR) value, which is one of the important parameters in road construction planning and design. This research was carried out using soil samples from several locations with varying levels of density. CBR testing was carried out in soil conditions with varying densities to evaluate the relationship between soil density and the resulting CBR values. The data obtained is analyzed using statistical methods to determine significant patterns or trends. The research results show that there is a positive correlation between the level of soil density and the CBR value, where an increase in soil density is associated with an increase in the CBR value. These findings provide important insights for road construction planning and soil quality assessment, and can be used as a reference in decision making regarding the selection and maintenance of soil materials for construction projects. The conclusion of this research is that increasing soil density can increase the CBR value, which in turn can increase the stability and bearing capacity of the soil in construction applications.

Abstract

Cost and time efficiency are two crucial aspects that influence the success of a construction project. Conventional methods are usually used because they are considered more flexible and easily adapted to field conditions. However, the precast method is increasingly in demand because it is claimed to be more efficient and faster in implementation. This research uses a case study approach by collecting primary and secondary data from planned work. Cost data is obtained from the detailed cost budget (RAB), while time data is taken from the project implementation schedule (time schedule). The analysis was carried out by comparing the total costs and time duration between conventional and precast methods using the 2018 Bina Marga Specifications. The research results show that the precast method has advantages in time efficiency, with an average construction time that is shorter than conventional methods. However, in terms of costs, precast methods tend to be more expensive in the initial stages due to the high production costs of precast elements.

Abstract

The development of communication technology in Indonesia has grown quite rapidly. The increasing needs of the community for telecommunications make cellular operators continue to improve services. To increase network capacity can be done by adding devices on telecommunication towers. The addition of devices on telecommunication towers brings consequences in the form of increased loads that must be carried by the telecommunication tower. The stability check of a 4-foot SST-type BTS tower with a height of 72m refers to the EIA/TIA-222-G standard and uses the MS Tower V6 program. The check includes several things, namely: the stress ratio that occurs in the tower element, tower sway, tower torsion, tower shift, and the reaction of the support that occurs. If the addition of devices in the telecommunication tower is still within the capacity limit of the tower, the addition of devices is not a problem. If one of the above criteria is passed even though the other criteria are safe, the tower structure is considered unsafe and must be recalculated. The results of the analysis when the tower was given an additional antenna load found that the tower did not meet 1 limit condition because the stress ratio exceeded the standard, which was 1.212 (>1). So it needs to be reinforced at the foot of the tower using the L60x60x6 profile. From the results of reinforcement at the foot of the tower, it was found that the stress ratio value < 1 with a value of 0,938 and the sway value < 0,5, which is worth 0.2303, so the tower has met the requirements.
