Abstract

Project delays are a highly unenviable condition. A school project in Waesama Sub-district, Buru Selatan Regency was delayed where 208 days of planning were not achieved, and were realized more than the plan. This study aims to distinguish the duration of the project using CPM and PDM on the project, as well as determine the optimal duration between the two methods. As well as obtaining critical jobs for CPM and PDM. CPM (Critical Path Method) is an AON (Activity on Node) method that only has one constrain, namely FS (Finish to Start). While PDM (Precedence Diagram Method) is an AON (Activity on Node) method that has 4 constrains FS (Finish to Start), SS (Start to Start), SF (Start to Finish), FF (Finish to Finish). The results of this comparative study found that there were differences in activities that were critical, there were also differences in duration after the use of these two methods. Where CPM produces a duration of 203 days, while PDM produces the most optimal duration of 200 days because it saves 8 days more than the duration of project planning. The use of PDM methods were more effective.

Abstract

Occupational Safety and Health (K3) is a science for anticipating, recognizing, evaluating and controlling hazards that arise in the workplace that can impact the health and welfare of workers. The risk of falling is the highest cause of accidents. The use of adequate safety equipment such as guardrails and helmets, as well as the implementation of security procedures such as inspection of non-permanent stairs and scaffolding can reduce the risk of accidents. occupational health on work performance (K3) in the Hitu Village Primary Hospital Development project. Analysis of the data used to calculate the analysis of the application of health and work to the project "Construction of the Hitu Village Pratama Hospital". f test. Based on the results of the analysis it was found that safety (X1) and health (X2) had a positive effect on work performance from the results of testing multiple linear regression analysis from the correlation table or partial correlation, where safety (X1) obtained a value of r = 0.766 with a significance of 0.000 < 0.05 Health (X2) obtained a value of r = 0.592 with a significance of 0.000 <0.05 For the Summary Regression Correlation Model (R) which simultaneously (together) between the variables Health (X1) and Safety (X2) , on Work Performance (Y) a value of r = 0.767 is obtained. Between the two aspects of safety and health on the work performance of the Hospital Development project Hitu Village Primary kit, the most dominant influence from the results of the partial test is the work safety aspect of 0.722 or 72.2%.
