Density Rate

The paper reviews the dependence of labor productivity on the number of workers within a unit of working area (i.e. workforce density) in the construction sector. The relevance of the problem is demonstrated. Some limitations of the linear model for the dependence, assumed in the construction sector, are discussed. These limitations are linked up with the neglect of labor productivity reduction due to the increased density. The proposed by some researchers concepts which account for the above factor are listed. Their drawbacks are indicated, and the necessity of further research is shown. A “hyperbolic model” is proposed, in which one worker productivity is constant for a certain workforce density rate and then it drops down with the increasing speed. Work productivity reduction in such model is described by the “hyperbolic growth” function. The primary approbation of the model was done for some construction operations at the nuclear power plant reactor building. The density rate was optimized (as per deadline reduction criterion) for this case according to the “hyperbolic model”.

Organizational performance is the end result of the work done to achieve organizational goals that have been established. All that is determined by the existence of good labor productivity. There are several things that affect the productivity of labor, including the provision of wages and discipline work. One way to reward and acknowledge the existence of manpower is through the provision of wages. In addition to wage factors, labor productivity can also be influenced by work discipline factors. This study aims to determine the effect of wages and discipline of work on the productivity of labor at the company's Duta Trans Jaya Jakarta. The population of the research ani there are 40 employees, so researcher uses saturated samples by using all the popolation. So the sample in this study is 40 people. Based on the above data it can be seen that the value for wage variables, and work discipline (simultaneously) has a significant effect on work productivity, where the significant value of F of 0.000 <0.05 so it can be concluded that Ha accepted and Ho rejected this means that there is A significant influence between wage and work discipline variables on work productivity at PT. Duta Trans Jaya Jakarta. Kata kunci:Provision of Wage, Discipline Work, Productivity of worker

Probabilistic seismic soil-structure interaction (SSI) analysis was performed for the Mu¨hleberg Nuclear Power Plant Reactor and SUSAN Buildings in support of the seismic probabilistic saftety assessment of the plant. An efficient hybrid method, employing computer programs SASSI2000 and CLASSI presented in a companion paper, was used in this analysis. The method takes advantage of the capability of SASSI2000 to analyze embedded structures with irregular geometry and the computational efficiency of CLASSI to rapidly perform the SSI response analysis of large structure models. Fixed base finite element models of the buildings were first developed from which the structure geometry, nodal masses, natural frequencies, and mode shapes were extracted. The structure embedments were modeled using SASSI2000. Impedance functions and scattering vectors were calculated by imposing rigid body constraints to the embedded foundation. The fixed base structure dynamic properties and the foundation impedances and scattering functions were input to CLASSI to perform the response analysis. The probabilistic analysis was performed following the Latin Hypercube Simulation (LHS) approach documented in NUREG/CR-2015. Variables defined by probability distributions were sampled according to a stratified sampling approach. The combination of the parameters for each simulation was determined by Latin Hypercube experimental design. Variables in the LHS included the earthquake ground acceleration time histories, structure stiffness and damping, and soil stiffness and damping. Thirty response simulations were performed using CLASSI in which the variable values were randomly selected. The use of CLASSI has the advantage that the response analysis simulations can be executed in a fraction of the time that would be required with SASSI2000 alone. For each simulation, in-structure response spectra (ISRS) were calculated at selected locations in the buildings. Probabilistic distributions, described by the median and 84th percentile response spectra, were calculated from the thirty simulations. The probabilistic ISRS are subsequently used in the seismic fragility evaluations of selected essential equipment.

Artinya, motivasi berpengaruh besar terhadap penigkatan produktivitas kerja.   The results of the study explained that the motivation variable turned out to be dominated by the opinion that states agree to motivational variables into numbers mayorias by 43%, the answers to which states could not agree by 34%, the answer hesitation by 17%, the answers do not agree 5% and were answered very agreed to have a figure that is equal to 1% minority. Variable labor productivity turned out to be dominated by the opinion that states agree to variable labor productivity into numbers the majority, ie 46%, an answer that states could not agree by 32%, the answer hesitant at 18%, the answers do not agree to 3%, and the answer strongly disagree have minority numbers: 1%. While the magnitude of the effect of motivation to work productivity that is equal to the independent variable (motivation to work) affect the dependent variable (labor productivity) of 50.3% and the balance of 49.7% is expected to be influenced by other factors not examined further by investigators but can ditelitu by other researchers as a benchmark for researched and developed again. The conclusion of this study namely that perediks motivas influence on the productivity of labor is positive. That is, the motivation big influence on the progressive increase in labor productivity.
