The Most Influential Factor as The Cause of Delays in Aluminum Form Work in The Sakura Project, East Jakarta

Abstract

Project development in Indonesia, especially DKI Jakarta continues to grow, especially in the construction of a multi-storey building concept. These high-rise buildings, including apartments, offices, and flats, have different construction methods. The construction method used in the construction of buildings with multilevel concepts is now more advanced, using a method called aluminum formwork. Aluminum formwork work in several projects in multi-storey buildings sometimes has problems in its work which can cause delays, one of which is in the Sakura Project, East Jakarta. For example, delays that occur in aluminum formwork work, namely in the delivery of materials and the lack of skilled workers on the job. This can also be caused by executors who are used to taking project work for granted and not learning from it. Therefore, with delays in aluminum formwork work, the purpose of this study was to determine the most influential factors causing delays in aluminum formwork work. The research method used is descriptive quantitative with a survey approach where the data collection technique uses questionnaires, interviews and documentation, and is analyzed into factor analysis with the help of SPSS software. The results of this study indicate that the factors that cause delays in aluminum formwork work are labor factors with a value of 65%, material factors with a value of 71%, equipment factors with a value of 62%, place characteristic factors with a value of 69%, managerial factors with a value of value of 58%, financial factors with a value of 72%, and external factors with a value of 68%. Thus, it can be concluded that the factor causing the delay that occurred in the aluminum formwork work at the Sakura Project, East Jakarta, which is the most influential or dominant factor, is the financial factor, while the factor that has the least influence is managerial factor.
