Abstract

Environmental damage and global warming has become an issue in the world. Developments in the construction project has a large influence in environmental change on the surface of the earth. Construction activities start from the constructing stage to the operating stage. Green construction is one part of the sustainable development that is required to participate in environmental sustainability. With this background, the author agreed to explain the criteria, stages of difficulty and obstacles in implementing Green Construction. Data collected by questionnaire method and data analysis using SPSS Statistics 26. The results of this study obtained the value of the Green Construction criteria that applied is waste project variables with an average value of 3,748 and the lowest is site project variables with average 3,198. The most dominant factor of difficulty in applying Green Construction is the water usage variable with an average value of 3,283 and the lowest difficulty in applying is the energy variable with an average of 2,817. The most challenging obstacle factor in implementing Green Construction is the cost factor with an average value of 4.00 and the lowest obstacle is the efficient design variable with an average of 2.96. Thus, from the results of this study is expected that the contractor can help more actively in improving the implementation of Green Construction in this construction project. Keywords: Green Construction, Obstacles, Level of Difficulty, Level of Application, Construction Project.

Abstract

The selection of work methods is very important, especially inthe deep pilling installation methode. Hydraulic Static Pile Driver (HSPD) piling equipment is selected since the method uses static pressure without negative impacts (noise and vibration) for residents around the project during piling process. However, it needs to find out effective and efficient levels, and also productivity of this method. This paper will discuss the productivity and some strategies to improve duration level of pilling equipment for Apple 3 Condovilla apartment project. From analysis, it was found that the productivity value was less than one (<1) for day 2 and 4. Several factors affect the productivity of the piling equipment, such as: late start or early quits on the schedule; equipment damage, worker skills, material production, material mobilization, location of pile material, and the final set of piling. Some strategies can be performed to improve duration, such as: workers coordination workers, periodic equipment maintenance, production, mobilization, and placement of materials. Keywords: Hydraulic Static Pile Driver, Pilling, Productivity.

Abstract

In the construction of a building project, one of the important elements in a building project is finishing work. Finishing work is a process of finishing or final completion of a building. The success of finishing work on the building depends on the success of each stage of the workers. Meanwhile, one of the factors influencing the success of a finishing work is the productivity of its workforce. This study aims to analyze productivity and what factors affect the productivity. This research uses the Relative Importance Index (RII) method, used a likert scale or a scale of 1 to 5 based on the perception of the level of interest of each respondent. Based on the results of the analysis, the performance of the project Transit Oriented Development (TOD) Pondok Cina Depok City on wall works is considered not good because the productivity index value is less than 1. Whereas the performance for floor and ceiling work is considered good because the productivity index value is more than 1. Factors that affect the productivity of finishing work are environment, work safety, education level, work experience, wages, and age. Keywords: Building, Finishing Work, Productivity.

Abstract

In a construction project, there are various kinds of very complex activities. Therefore, heavy equipment, especially Tower Cranes is used to assist the work on the construction project. The layout of the Tower Crane must be considered because the optimal location of the Tower Crane will result in efficient cycle times and productivity values. Thus, the purpose of this study is to obtain the factors that must be considered in determining the location of the Tower Crane, and the location of the Tower Crane that is the most optimal and efficient in the project under review. In this study, 3 scenarios will be conducted according to the feasible area and the location of the Tower Crane closing to the building structure in under construction. Scenario 1, is the existing location in project Y. In scenario 2, the setting out of location of Tower Crane 1 is moved to coordinates (152.10; 43.30) and Tower Crane 2 is moved to coordinates (41.36; 29, 38). Scenario 3, the location of Tower Crane 2 is set to coordinates (36.60; 21.38). Analysis and comparison of the cycle time and productivity of Tower Crane were conducted on this paper. Result of the lowest total cycle time of 17277.32 minutes was obtained in scenario 3, 1048.53 minutes faster than the existing condition (scenario 1). In addition, the highest productivity value was obtained in scenario 3, with 5078.00 kg/hour for Tower Crane 1 and 5559.73 kg/hour for Tower Crane 2. From analysis performed for (3) three scenarios, Scenario 3 was also considered as the most optimal scenario based on several consideration factors in determining the location of the Tower Crane. Keywords: Cycle Time, Optimization, Productivity, Scenario, Tower Crane.
