Optimalization Physical Environment Effects on Work Productivity for Assembly Operator with Response Surface Methodology

Abstract

The work environment greatly affects the level of work productivity of a person, it affects the increase of production, means and equipment production, occupational safety and health, and atmosphere of the work environment itself. The atmosphere of this working environment can be the lighting and temperature. This study discusses the optimization of lighting and temperature levels on the performance of the assembly operator with Response Surface Methodology. Experiment design using Central Composite Design (CCD). The experiment was conducted at the Industrial Engineering Design Laboratory. The range for lighting is 350 lux -700 lux and the temperature is between 24°C - 27°C. The experiments performed were the assembly of a light sleeper for 10 minutes. Output is the number of completed assemblies. The results showed that the optimal working environment conditions for lighting were 700 lux and temperature 24°C. While the most influential variable on the work of the operator is the lighting with coefficient value of 0.026.
