The delay will result in losses for the parties associated especially the owner and the contractor because generally accompanied conflict, the demands of time and cost as well as deviations from the quality of the completion of the project .the research is aimed to know the factors that most affect the delay of the projected Revitalization of the Taman Ismail Marzuki. Data collection techniques used is literature study, observarsi, interviews/questionnaires. The determination of the population in this research is taken from some of the respondents with the use of the sample. Data analysis in research this using validity test, reliability test, correlation test and regression test with the statistical program SPSS 26.Based on the analysis that has been done there are 11 variables that affect the delay of the work structure under the building of the guesthouse on the project to work withk revitalization of the taman ismail marzuki stage 1 and there are 3 variables that are dominant, namely the lack of expertise of most work, the design changes,the number of repair work.

Keywords Project Delays, The Dominant Factor

1.Introduction The project of Revitalization is an attempt to revive or glory with careful planning. The project of Revitalization of the Taman Ismail Marzuki is a form of government attention to the artists in an effort to enliven the back of the venue. With in Revitalisasinya Taman Ismail Marzuki is expected to be the center of arts international (Rahma, 2018) The project of Revitalization of the Taman Ismail Marzuki for phase one includes the construction of the Mosque of , Parking Building, and the Guesthouse. With plans starting time of workmanship from the date of 10 July 2019 targeted up to July 11, 2021 (project data TEAM 2020). On the implementation of the for the work of the structures under his own experience delays of 3% of the work plan of the structure below. The delay in the project will not cause adverse effects for the project. Therefore, the analysis of the causal factors of delay which is very important to be aware. Of the factors that cause delays in the project then it can be evaluated to be the result of the maximum.

2.Literature Review 2.1 Project The project is a set of activities that relate to where there is a start point and end point as well as the specific results, the project is usually cross-functional organization that requires a variety of expertise (skills) from a variety of professions and organizations. Each project is unique, even no two projects are exactly the same (Dipohusodo, 1996).

2.2 Construction Project Delay Delay in construction projects is increasing the execution time of the settlement that has been planned and listed in the contract documents (Hassan et al., 2016).

2.3 Time Schedule or Scheduling Time schedule or scheduling is the translation of the planning of the project into a sequence of steps of the implementation of the work to achieve the goals (Michael R Solomon et al., 2017)

4.1 Test Validation The Output of the test validation is declared valid if r count > r table. On the contrary , if r hitung < r table , then the data is not valid. Then with the number of respondents as many as 31 (three twenty - one) take the level of significance of 5%, table R product momentnya by 0,3009 (Ghozali, 2005).

Table 4.1 Test The Validity Of The Instrument R Var R tables Desc. calculate x1 0,3009 0,700 Valid x2 0,3009 0,288 Invalid x3 0,3009 0,685 Valid x4 0,3009 0,572 Valid x5 0,3009 0,377 Valid x10 0,3009 0,486 Valid x11 0,3009 0,108 Invalid x13 0,3009 0,529 Valid x14 0,3009 0,617 Valid x21 0,3009 -0.061 Invalid x24 0,3009 0,679 Valid

From the analysis of table 4.1, there are 8 (eight) independent variables that meet a condition where the count r> (more massive) than r table, so that the analysis can proceed by performing a reliability test.

4.2 Reliability Test In table 4.2 are the results of the test reliability which shows the value of cronbach's Alpha of 0,753. Where is the item-item instrument variable is declared reliable, because it has a value is greater than 0.60 (Ghozali, 2005).

Y=20.111+1.329 X1+1.039 X3+THE 1,347-X4+0.596 X13+0.547 X14+1.780 X24 Here's an explanation of the linear regression equation above: 1. The regression coefficient of the lack of labor skills is positive value means that the moment happened to the lack of expertise of the labor then the delay that occurs in the project will also increase. Similarly, when the labor skills improved then the delay in the project will also decline. The lack of labor skills will increase the delay in the project amounted to 1.329 2. The coefficient of regression of the change of the design is positive value means that the moment happened many changes to design then the delay that occurs in the project will also increase. Similarly, when the design changes a little bit then the delay in the project will also decline. The design changes will increase the delay in the project amounted to 1.039 3. Regression coefficient of the undercooked scheduling is positive value means that the moment happened scheduling less mature then the delay that occurs in the project will also increase. Similarly, when the presence of scheduling mature then the delay in the project will also decline. The presence of scheduling is that less ripe increase the delay on the project of the 1,347.

4. The regression coefficient of the lack of labor is positive value means that the moment happened to the lack of labor then the delay that occurs in the project will also increase. Similarly, in the event of availability of labor, then the delay in the project will also decline. Lack of manpower increase the delay in the project amounted to 0.596. 5. The regression coefficient of delay the delivery of the material is positive value means that the moment happened late delivery of the material then the delay that occurs in the project will also increase. Similarly, at the time of delivery of material on time then the delay in the project will also decline. Material delivery delays increase the delay on the project of 0.547. 6. The coefficient of regression of the lots of repair work is positive value means that the moment happened many repair work then the delay that occurs in the project will also increase. Similarly, in the event of not much.repair work then the delay in the project will also decline. The amount of work repair increase the delay on the project by 1.780. Having obtained the results of the regression test furthermore, the researchers perform a validation of the expert, i.e. with variable-a variable that has passed the test, next ask kepakar for requested input and suggestions, concerning the varel smoke this is X1, X3, X4, X13, X14 and X24 has an influence. to delay the work of the structure under the building of the guesthouse on the project to work withk revitalization of the taman ismail marzuki stage 1. The following are the results of the final validation by the expert : Tabel 4.7 Validation Expert Experts 1 Experts 2 Experts 3 Experts 4 Number Variabel Conclusion Yes No Yes No Yes No Yes No Lack of x1 workforce √ √ √ √ Yes expartise Design x3 √ √ √ √ Yes changes Undercooked x4 √ √ √ √ No shedulling Lack of x13 √ √ √ √ No manpower Material x14 delivery √ √ √ √ No delay Lost of x24 √ √ √ √ Yes repair work

The results of the validation of the expert obtained three variables are dominant to delay work structure under the building of the guesthouse on the project to work withk revitalization of the taman ismail marzuki stage 1, namely the lack of labor skills, the design changes and the amount of repair work.

5.Conclusion and Suggestions 5.1 Conclusion From the research that has been done on the analysis of the factors delay the work of the structure under the building this in the revitalization of taman ismail marzuki stage 1, it can be concluded: 1. Factors-factors that affect the delay of the work structure under the building of the guesthouse on the project of revitalization of the taman ismail marzuki stage 1 , namely the lack of expertise of tenaga work, the incompleteness of the granting of detail drawings, design changes, scheduling less mature, the lack of proper estimation, the lack of discipline of labor, the weather not support, lack of manpower, material delivery delays, lack of communication or coordination, the number of repair work. 2. The dominant factor causing delay in the work of the structure under the building of the guesthouse on the project of revitalization of the taman ismail marzuki stage 1 , namely the lack of labor skills, design changes, and the amount of repair work. Of the three factors dominant that has been obtained from the validation expert, there is one of the most dominant factors that cause delay in the work of the structure under the building of the guesthouse on the project of revitalization of the taman ismail marzuki stage 1 which is the number of repair work with the results of the regression test most.

5.2 Suggestions From the results of the research that has been done, then to anticipate delays in the work of the project, it is recommended the following things : 1. Due to the factor of the lack of labor skills to be improved regarding the human resource of personnel with the included training support to the progress of the company.
