Effect of Work Safety and Health Knowledge on Construction Workers in Cawang-Tomang Cengkareng Toll Road Projects

Safety at the location of road works is an important part that is often overlooked in the construction and maintenance of roads. Management of the safety of the road work location is the responsibility of the road manager. In general, knowledge about Occupational Health and Safety (OSH) is very broad, but there are several OHS components that are considered important to be used as a benchmark for understanding OSH. These components are K3 Definition and Initiation, K3 Management System (SMK3), Personal Protective Equipment (PPE), K3 Facilities and Infrastructure, OHS Risk. Research on the influence of occupational safety and health knowledge on occupational health on construction worker behavior was carried out to determine the effect of K3 knowledge variables together on the behavior of construction workers. And to know the effect of K3 knowledge variables partially on the behavior of construction workers. From the results of the study, it can be concluded that there is a relationship or a low level of correlation between K3 Knowledge and Workers' Behavior while the value of the Determination Coefficient (adjusted r square) is 0.033, which means only 3.3% of K3 Knowledge aspects that affect Construction Worker Behavior and the remaining 96.7% is influenced by other variables. Based on the results of the T-test calculation using the method of calculation of Multiple Linear Regression the value of t count t table, there is no significant effect of K3 knowledge variables (Definition and Initiation, Management Systems, Personal Protective Equipment, Facilities and Infrastructure, Risk) jointly towards Construction Worker Behavior on the Toll Road Development Project.
