Abstract

In planning and controlling a project, it is often faced with various obstacles, for example, there is a shortage of materials, errors in the work order. In this project there was a delay due to a pandemic which caused the project to be hampered which initially could run according to schedule but became not according to the specified schedule. To minimize the impact of risks that occurred, a project scheduling method was developed using a probabilistic duration, one of which was PERT ( Program Evaluation and Review Technique). In this study, PERT (Program Evaluation and Review Technique) simulation was implemented which was implemented in the Grand Shamaya basement construction project based on the optimistic, pessimistic, and possible durations obtained from the survey results by the project management. PERT calculation using Microsoft Project 2013 software which produces an optimistic duration of 530 days, then for a possible duration of 535 days, a pessimistic duration of 551 days, and finally for a simulation result duration of 534.6 days. The difference in the schedule for the basement construction project of the Grand Shamaya Surabaya apartment when compared to scheduling using the PERT (Program Evaluation and Review Technique) method is the length of duration and the probability of project completion. So the duration of the plan schedule for 535 days produces a probability of 53.19%.

Abstract

Infrastructure and technology development in the construction sector are rapidly evolving, particularly in Indonesia. Because practically every construction building is built of concrete, this supports the increased use of natural materials as raw materials for creating concrete to keep up with the world's rapid development. As a result, new technologies are required to limit the use of substitute elements in concrete mixtures while also minimizing environmental damage. The researchers used clay tile waste and charcoal ash as a substitute for coarse aggregate and cement in the concrete mix in this final project. This study uses an experimental approach with a total of 36 samples of cylindrical samples with a size of 10cm x 20cm, a substitution variation of 20%, 25% of total coarse aggregate, and charcoal ash 5% of total cement weight. On days 3, 7, 14, and 28, the test object will be slumped to see how workable it is and how strong it is. According to the findings, the higher the percentage in the concrete mixture, the lower the slump value, and the compressive strength test results. The highest is the 25% GTL substitution variation. At the age of 28, 5% AA equals 27.3 MPa. The results of testing the compressive strength of concrete with the substitution of tile waste reached the quality of K-225.
