<![CDATA[The performance of human resources in the project environment is an important factor affecting the smooth running of the work. Lack of worker performance will affect the process of completing a project. Variables that affect worker performance are ability, motivation, and discipline along with their indicators. The purpose of this study was to determine the effect of the ability, motivation, and work discipline on the performance of building construction workers in Jabodetabek. The research method was carried out by distributing questionnaires to 40 building construction workers in Jabodetabek. Then the data were analyzed using Statistical Variance-Based Structural Equation Modeling (VB-SEM) using the Smart Partial Least Square (SmartPLS). After doing the analysis, it was found that the ability variable has a very significant and strong effect on the performance of workers, meaning that the presence of good worker abilities can cause worker performance to increase. The motivation variable has an effect but not a sign on the performance of workers and the discipline variable has a significant but not strong effect on the performance of workers, meaning that discipline can improve worker performance so that it can help increase company productivity to be optimal.
